Description
- 1. Field of the Invention
- The present invention relates to heat spreaders, and more particularly to a heat spreader having a vapor chamber for transfer or dissipation of heat from a heat-generating component and a heat dissipation apparatus using the same.
- 2. Description of Related Art
- Nowadays, heat spreaders are used in electronic products for dissipating heat generated by electronic components such as CPUs. Typically, the heat spreader includes a vacuum vessel defining therein a vapor chamber, a wick structure provided in the chamber and lining an inside wall of the vessel, and a working fluid contained in the wick structure. The heat spreader is arranged to have an intimate contact with the electronic component so as to form a heating area at a middle portion of the heat spreader corresponding to the electronic component and a cooling area at the other portion of the heat spreader.
- As the electronic component is maintained in thermal contact with the heat spreader, the working fluid contained in the wick structure corresponding to the heating area vaporizes. The vapor then spreads to fill the chamber, and wherever the vapor comes into contact with the cooling area of the vessel, it releases its latent heat of vaporization and condenses. The condensate returns to the heating area via a capillary force generated by the wick structure. Thereafter, the condensate frequently vaporizes and condenses to thereby remove the heat generated by the electronic component.
- As progress continues to be made in electronics area, the electronic components are made to be more powerful while occupying a smaller size. Thus, the heating area needs to transfer more heat to the cooling area of the heat spreader. In contrast, the heating area of the heat spreader is decreased as the size of the electronic component is decreased, and the cooling area of the heat spreader is commensurately increased. Therefore, the heat flux density between the heating and the cooling areas of the heat spreader is increased. Accordingly, the wick structure needs to have more powerful heat transfer capability. However, the wick structure of the heat spreader selected from the conventional types, such as mesh, fiber, fine grooves, and sintered powder, cannot satisfy such requirement, which further limits the increase for the heat transfer capability of the heat spreader. Therefore, it is need to provide a heat spreader which contains a wick structure having more powerful heat transfer capability.
- The present invention relates, in one aspect, to a heat spreader for transfer or dissipation of heat from a heat-generating component and a heat dissipation apparatus using the same. The heat dissipation apparatus includes a heat sink and a heat spreader. The heat spreader includes a heating area and a cooling area, and defines a vapor chamber therein. A plurality of artery meshes are arranged in the vapor chamber and extend from the heating area outwardly towards the cooling area. Wick structures are respectively attached to a top surface of a base plate and a bottom surface of a top cover of the heat spreader. The artery meshes are sandwiched between the wick structures. A working medium is contained in the artery meshes and the wick structures. In addition to be transferred vertically upwardly to reach a heat sink on the heat spreader by vaporization of the working medium, heat absorbed by the heating area of the heat spreader can be transferred to the cooling area horizontally via the artery meshes.

Acooling area 13 is formed at the other portion of theheat spreader 10 and surrounds theheating area 11, transferring the heat to theheat sink 30 and dissipating the heat to the surrounding environment. That is, thecooling area 13 directly dissipates the heat to the surrounding environment at a bottom of theheat spreader 10, and transfers the heat to theheat sink 30 at a top thereof. - The
wick structures 15 includes first andsecond wicks base plate 12 and thecovering plate 141, and sixartery meshes 151 sandwiched between the first and thesecond wicks second wicks artery meshes 151 are symmetrically disposed at two opposite sides of theheating area 11.

That is, each of theartery mesh 151 has aninner end 1513 located at theheating area 11 of theheat spreader 10 and anouter end 1514 located at thecooling area 13 thereof. Therefore, the working medium can move horizontally between the heating and thecooling areas artery meshes 151. - Referring to
FIGS. 4 and 5 , theartery mesh 151 is a flexible elongate hollow tube which is woven from a plurality of metal wires such as copper wires, aluminum wires, or stainless steel wires. Alternatively, theartery mesh 151 can also be woven from a plurality of fiber wires. In this embodiment, theartery mesh 151 is woven from a plurality of copper wires. A diameter of the copper wire can be about 0.05 mm. A plurality of pores are defined in awall 1512 of theartery mesh 151. The pores communicate the artery meshes 151 with the first and thesecond wicks heat spreader 10.

In this embodiment, the thickness of thewall 1512 of theartery mesh 151 is about 0.2 mm. - In operation of the heat dissipation apparatus, the working fluid contained in the
second wick 15 b corresponding to theheating area 11 vaporizes due to the heat absorbed from the heat generatingelectronic component 20. The vapor then spreads to fill thevapor chamber 16, and wherever the vapor comes into contact with the coolingarea 13 of theheat spreader 10, it releases its latent heat of vaporization and condenses. The vapor moves vertically upwardly to transfer the heat to theheat sink 30. Furthermore, the vapor moves horizontally along thechannels 1510 of the artery meshes 151 to transfer the heat to thecooling area 13 of theheat spreader 10. The heat is therefore directly dissipated to the surrounding environment at the bottom of theheat spreader 10 and evenly transferred to theheat sink 30 at the top thereof, which further dissipates the heat to the surrounding environment.
