The circulation channels are the micro-channels or/and narrow channels and sequentially and alternately arranged in parallel, inlet and outlets of the circulation channels arranged at least one side are arranged on two sides of each of the parallel-arranged channels, the inlets are connected with corresponding channels through transverse distributary channels, and the outlets are connected with corresponding channels through transverse confluence channels. The heat exchanger adopting the micro-channels or/and narrow channels on two sides or multiple sides are good in heat exchange effect, capable of saving energy and wide in application range.
Description
Technical field
The present invention relates to a kind of heat exchanger, especially relate to the heat exchanger that a kind of both sides or many sides adopt microchannel Huo ∕ and thin passage.
Background technology
Though existing microchannel heat sink has better radiating effect; But because the restriction of its version, not enough below yet existing: the microchannel flow process is long, and fluid flow resistance increases; Wind effluent journey is too short; Wind utilize effect relatively poor, correspondingly increased the blower fan power output, thereby caused energy waste; Flow is difficult to increase, and is difficult to the heat exchange of formation scale; Be of limited application, can not do heat exchange between liquid and the liquid, only limit to heat exchange between gas and liquid or gas and the gas.
Before this; Liu Xiaojiang has applied for an invention " a kind of cellular board fin heat exchanger and assembly of pure adverse current ", and application number is: 201210029210.4, also applied for utility model " a kind of cellular board fin heat exchanger and assembly thereof " on the same day; Application number is: 201220042482.3; The side of having only this heat exchanger adopts microchannel or thin passage, and opposite side adopts the fin form of the gas that suits away or walks the circular hole form of high temperature flue gas, and this side must form the import and export form of oneself at two ends; During use, only be suitable for the heat exchange exchange between liquid and the gas.
Summary of the invention
Technical problem to be solved by this invention is, a kind of heat exchange better effects if is provided, can save energy, and the wider both sides of the scope of application or the many sides heat exchanger that adopts microchannel Huo ∕ and thin passage.
The technical solution adopted for the present invention to solve the technical problems: a kind of both sides or many sides adopt the heat exchanger of microchannel Huo ∕ and thin passage; Comprise and be used for the circulation that different medium is carried out exchange heat; It is characterized in that: said heat exchanger adopts pure countercurrent heat exchange method; Said circulation is microchannel Huo ∕ and thin passage, alternately is arranged in parallel in order, and has the import of the logical channel of an effluent and the both sides that outlet is located at the passage that is arranged in parallel respectively at least; Said import links to each other with respective channel through horizontal shunt conduit, and said outlet links to each other with respective channel through the horizontal channel that confluxes.
Further, the preferred 0.3-1mm of said microchannel diameter, the thin preferred 1-6mm of channel diameter.
Further, the transverse shape of said microchannel or thin passage can be circle, trapezoidal, triangle, rectangle, hexagon, semicircle or square.
As everyone knows; Molecule is when doing warm-up movement, and it has free path, and the free path length of different molecular is different; And this free path has determined the macroscopic property of molecule to a great extent, and intermolecular mutual collision is exactly a heating power transmittance process when doing warm-up movement like molecule.In order more effectively to carry out the heating power transmission, the present invention all adopts microchannel Huo ∕ and thin passage through changing the heat exchanging fluid channel design, makes it more near the length dimension of fluid molecule free path, thereby improves heat exchange efficiency.Because the raising of heat exchange efficiency, thereby can relatively reduce the heat exchanger size, manufacturing cost is reduced, simultaneously, can avoid the existing microchannel of picture flow process long and cause the lower phenomenon of microchannel outlet section heat exchange efficiency.
The present invention adopts pure countercurrent heat exchange method, has the advantage of countercurrent flow: not only mean temperature difference is maximum, and can make temperature gradient field and velocity field form minimum cosine angle, reaches a synergy preferably, thereby improves the coefficient of heat transfer; In addition, can also make a side liquid outlet temperature, can improve temperature efficiency as far as possible near the opposite side fluid inlet temperature.
Compared with prior art, microchannel or thin passage that the present invention can gather many suitable length flow processs form a very passage of big collection sectional area, to be used for the heat exchange of scale property; Applied widely, not only can be used for heat exchange between gas and liquid or gas and the gas, also can be used for heat exchange between liquid and the liquid, and good effect of heat exchange; Can be used for the exchange heat between multiple fluid and a kind of fluid, multiple fluid is alternately arranged each other in order; Fluid goes out after on flowing to, can realizing the precursor, and laggard person goes out earlier, can act synergistically fine optimization field, the cross section flow velocity is reached evenly, thereby help heat exchange, and improve the coefficient of heat transfer; When fluid viscosity contained suspended particles than big or fluid, this fluid side adopted thin passage more suitable.

The specific embodiment
Below in conjunction with embodiment the present invention is described further.
With reference to Fig. 1-3, the heat exchanger 1 of microchannel is adopted in the both sides of present embodiment, comprises that being used for medium A carries out the microchannel 1-1 of exchange heat and be used for the microchannel 1-2 that medium B carries out exchange heat, and said heat exchanger 1 adopts pure countercurrent heat exchange method; Saidly be used for microchannel 1-1 that medium A carries out exchange heat and be used for the microchannel that microchannel 1-2 that medium B carries out exchange heat is diameter 0.5mm; And alternately be arranged in parallel in order; The said medium A that is used for is carried out the microchannel 1-1 of exchange heat, is used for import and outlet that medium B carries out the microchannel 1-2 of exchange heat and is located at the both sides of the passage that is arranged in parallel respectively; Said import links to each other with respective channel through horizontal shunt conduit, and said outlet links to each other with respective channel through the channel that laterally confluxes.Certainly, it is the thin passage of 1-6mm that diameter also can be adopted in said microchannel, or the combination of microchannel and thin passage etc.
