Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit under 35 U.S.C. § 119 from Korean Patent Application No. 2005-48930, filed on Jun. 8, 2005, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference in its entirety.

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present general inventive concept relates to a heat radiation member usable with a card type electronic component and a display apparatus having the same, and more particularly, to a heat radiation member usable with a card type electronic component, such as a Point Of Deployment (POD) card, and a display apparatus having the same.
2. Description of the Related Art
A Point Of Deployment (POD) card is a type of conditional access card, and refers to a card that is capable of receiving a fee-broadcasting signal when membership is determined by a member's information of a cable TV, a satellite broadcasting, or the like.
Generally, the POD card is a Personal Computer Memory Card International Association (PCMCIA) card type including a smart card, and is disposed at a card mounting part provided in a display apparatus such as a Liquid Crystal Display (LCD), a Plasma Display Panel (PDP), or the like.
FIG. 1 is a perspective view of a conventional heat radiation member for a card type electronic component. A mounting structure of a POD card 40 will be described while referring to FIG. 1. The POD card 40 is disposed at a card mounting part 134 provided in a display driving part 115. The card mounting part 134 is provided with a receiver 133 for accommodating the POD card 40, and a connector (not shown) for connecting with the POD card 40. On a side of the receiver 133, a card withdrawing bar 137 is provided for withdrawing the accommodated POD card 40.
A cooling fan 130 is provided in the card mounting part 134, for dissipating heat generated from the POD card 40. An air inhalation hole 117 is provided in a lateral side of a rear cover 112 corresponding to the card mounting part 134. The POD card 40 generates the heat while in use, and when the generated heat is not properly cooled, the heat is transferred to the display driving part 115 and an image display part, thereby causing malfunction. Therefore, as illustrated in FIG. 1, the conventional heat radiation member is provided with the cooling fan 130 at an upper end of the card mounting part 134 and uses a cooling method to dissipate heat by forcibly producing a convective current using the cooling fan 130.
However, the conventional heat radiation member for the card type electronic component generates noise because of the cooling fan 130, and if the cooling fan 130 does not succeed to efficiently dissipate the heat, image quality deteriorates and the display driving part 115 and the image display part malfunction. Further, manufacturing expenses are increased when using the cooling fan.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Reference will now be made in detail to the embodiments of the present general inventive concept, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. The embodiments are described below in order to explain the present general inventive concept by referring to the figures.
FIG. 2 illustrates a structure of a heat radiation member 30 usable with a card type electronic component according to an embodiment of the present general inventive concept. FIG. 3 illustrates separate parts of the heat radiation member 30 of FIG. 2. As illustrated in FIGS. 2 and 3, a heat radiation member 30 usable with a card type electronic component includes a heat radiator 32 formed with a plurality of cooling fins 35, and a card mounting part 34 having a receiver 33 which couples to the heat radiator 32 and accommodates the card type electronic component to transfer heat generated by the card type electronic component to the heat radiation member 30. Herein, the receiver 33 may be provided with an elastic member 36 to press the accommodated card type electronic component toward the heat radiator 32.
The card mounting part 34 includes the receiver 33 to accommodate a POD card 40. The card mounting part 34, as illustrated in FIG. 3, may be disposed on a display driving part 15, but is not limited thereto, and may be provided anywhere as long as the card mounting part 34 is electrically connecting with a connector 17. The heat radiator 32 may be provided on a side of the card mounting part 34 to dissipate the heat generated from the POD card 40 to the outside. A card withdrawing bar 37 may be provided on a side of the card mounting part 34 to withdraw the POD card 40 from the receiver 33.
The receiver 33 is provided on the card mounting part 34 to accommodate the POD card 40. The receiver 33 may be provided as a pass through hole in which both sides thereof are opened along an insertion path in an insertion direction of the POD card 40, or may be provided as a receiving groove in which one side of the receiver 33 may be opened. When the both sides of the receiver 33 are opened, the connector 17 to electrically connect the POD card 40 is provided in an opposite side of an insertion hole in which the POD card 40 is inserted. If the receiver 33 is provided as the receiving groove, which is opened with only the insertion hole, the connector 17 may be provided on a side opposite to the insertion hole of an inner wall of the receiver 33. In other words, if the receiver 33 has both sides opened along the insertion path, the POD card 40 may be inserted at one side, and the connector 17 is disposed at the other side. However, if the receiver 33 has only one side opened along the insertion path, the connector 17 may be disposed on the inner wall opposite to the insertion hole.
A side of the receiver 33 coupled with the heat radiator 32 may be opened (refer to FIG. 2). In this case, the POD card 40 is directly in contact with the heat radiator 32, thereby efficiently transferring the heat generated from the POD card 40 to the heat radiator 32. The elastic member 36 accommodated in the receiver 33 forces the accommodated POD card 40 toward the heat radiator 32 so that the POD card 40 is forced into close contact with the heat radiator 32. The elastic member 36 may be provided as a leaf spring in which a middle area is bent toward the heat radiator 32. Therefore, if the POD card 40 is accommodated into the receiver 33, the POD card 40 is closely adhered to the heat radiator 32 by the leaf spring, thereby efficiently transferring the heat generated from the POD card 40 to the heat radiator 32. Further, the elastic member 36 may be provided as an elastic pad such as a sponge.
The plurality of cooling fins 35 is provided on a side of the heat radiator 32 to dissipate the heat transferred to the heat radiator 32 from the POD card 40. The cooling fins 35 have large surface areas to perform a maximum amount of heat exchange with external air.
As described above, the heat radiation member usable with the card type electronic component 30 according to the present embodiment provides the heat radiator 32 and the card mounting part 34 separately, so that it is easy to manufacture the heat radiation member 30 for the card type electronic component. Further the POD card 40 is directly in contact with the heat radiator 32, so that the heat is transferred by conductivity, thereby enhancing cooling efficiency. Further, the heat radiation member 30 of present embodiment does not use a cooling fan, thereby decreasing noise and saving additional expenses.
FIG. 4 is a perspective view illustrating a heat radiation member 30′ usable with a card type electronic component according to another embodiment of the present general inventive concept. Some of the components of the present embodiment are similar to components of the embodiment illustrated in FIGS. 2 and 3, and may be referred to by same reference numbers. As illustrated in FIG. 4, the heat radiation member 30′ usable with the card type electronic component according to the present embodiment includes a heat radiator 32 and a card mounting part 34. The heat radiator 32 has a main body 31 formed with a plurality of cooling fins 35, and the card mounting part 34 comprises a receiver 33 to accommodate a POD card 40. Herein, the receiver 33 may include an elastic member 36′ which presses the accommodated POD card 40 toward the receiver 33 (as opposed to the embodiment of FIGS. 2 and 3 where the elastic member presses the POD card 40 towards the heat radiator 32).
The main body 31 may include the receiver 33 to accommodate the POD card 40, and the plurality of cooling fins 35 to dissipate the heat generated from the POD card 40 to the outside. The main body 31 may have various shapes that receive the POD card 40. Further, the main body 31, as illustrated in FIG. 4, may couple to a display driving part 15 of a display apparatus 10 (see FIG. 5), and to a rear cover 12. The main body 31 may be made of a heat conductive material such as aluminum, copper, titanium, and the like.
The receiver 33 may be formed in the main body 31 to accommodate the POD card 40. A shape of the receiver 33 may correspond to a shape of the POD card 40 to be accommodated therein. When using a card type electronic component of a different type, the receiver 33 may correspond to the shape and the size thereof. The receiver 33 may correspond to the size of the POD card 40 so that the POD card 40 is in contact with an inner wall of the receiver 33. In this case, the heat generated by the POD card 40 is conducted through the receiver 33 to be transferred to the cooling fins 35, thereby being discharged and/or dissipated by a heat-exchange between the cooling fins 35 and the external air that surrounds the cooling fins 35.
As illustrated in FIG. 4, the heat radiation member 30′ further comprises the elastic member 36′ to press the POD card 40 toward the receiver 33 so that the POD card 40 is in close contact with the receiver 33. For example, the elastic member 36′ may be provided as the leaf spring or a pad type. The elastic member 36′ applies pressure on the POD card 40, thereby increasing a contact area between the POD card 40 and the main body 31 to conduct more heat to the cooling fins 35.
The receiver 33 may be provided as a pass through hole in which both end sides of the receiver 33 are opened, and may be provided as a receiving groove in which a side of the receiver 33 is opened. When the receiver 33 is provided as the pass through hole, the connector 17 may be provided in an opposite side of an insertion hole inserted with the POD card 40, to electrically connect with the POD card 40. When the receiver 33 is provided as the receiving groove, the connector 17 may be provided in a side of an inner wall of the receiver 33.
The receiver 33 may be provided with a card withdrawing bar 37 (same as illustrated in the embodiment of FIG. 2) to withdraw the POD card 40. The card withdrawing bar 37 may be projected from the receiver 33 when the POD card 40 is inserted. In this case, the inserted POD card 40 pushed by the card withdrawing bar 37 to withdraw the POD card 40 from the receiver 33.
As described above, in the heat radiation member 30′ usable with the card type electronic component according to the present embodiment, the receiver 33 to accommodate the POD card 40 is integrally formed with the cooling fins 35 which discharge and/or dissipate the heat generated from the POD card 40, thereby minimizing a volume of the heat radiation member for the card type electronic component, and enhancing the cooling efficiency by efficiently transferring the heat from the POD card 40 to the cooling fins 35. Because the various embodiments present general inventive concept do not use a cooling fan, there is no noise generated and the additional expenses caused by using a cooling fan are avoided.
An operation of the heat radiation member (30 or 30′) usable with the card type electronic component incorporated in a display apparatus 10 will be described with reference to FIG. 5. The heat radiation member (30 or 30′) usable with the card type electronic component according to the above described embodiments of the present general inventive concept may be employed in the display apparatus 10 illustrated in FIG. 5.
FIG. 5 is an exploded perspective view illustrating the display apparatus 10 having the heat radiation member 30 (or 30′) to dissipate heat generated by the card type electronic component. As illustrated therein, the display apparatus 10 of the present embodiment includes an image display part 13 to display images, a display driving part 15 to drive the image display part 13, and a front cover 11 and a rear cover 12 to respectively accommodate the display part 13 and the display driving part 15 and to form an outer appearance of the display apparatus 10.
The display driving part 15 is provided behind the image display part 13, and a connector (not shown) is provided in an area of the display driving part 15 to electrically connect with a POD card 40. A card insertion hole 16 which corresponds to the receiver 33 is provided in the rear cover 12 so that the POD card 40 is detachably inserted therein from outside the display apparatus 10.
The POD card 40 is inserted into the receiver 33 of the heat radiation member 30 (or 30′) through the card insertion hole 16 provided in the rear cover 12. An end part of the inserted POD card 40 is electrically connected with the connector 17 through the receiver 33, and a remaining part of the POD card 40 (except for the end part) maintains contact with the receiver 33. The elastic member 36′ may press the POD card 40 toward the receiver 33 to force a contact between the receiver 33 and the POD card 40, as described with reference to the embodiment of FIG. 4. Alternatively, the elastic member 36 may press the POD card 40 toward the heat radiator 32, as described with reference to the embodiment of FIGS. 2-3. When the heat radiation member 30 is provided as in the embodiment illustrated in FIG. 2, a side coupled with the heat radiator 32 in the receiver 33 may be opened. In this case, the POD card 40 is directly in contact with the heat radiator 32, thereby efficiently transferring the heat from the POD card 40 to the heat radiator 32. Therefore, the heat generated by the POD card 40 is transferred to the cooling fins 35 through the contacted heat radiator 32, and the heat is dissipated by heat-exchange with the external air around the cooling fins 35.
Therefore, the display apparatus 10 having the heat radiation member 30 (or 30′) usable with the card type electronic component may efficiently dissipate the heat generated by the POD card 40, so that the heat generated by the POD card 40 is not transferred to the display driving part 15 or the image display part 13, thereby preventing deterioration of the image quality and malfunction of the display apparatus 10. Further, because a cooling fan is not used, noise is not generated and the additional expenses caused by using of the cooling fan are avoided.
Although a few embodiments of the present general inventive concept have been shown and described, it will be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the general inventive concept, the scope of which is defined in the appended claims and their equivalents.
