Description
Technical field
The present invention relates to a kind of heat exchanger, especially relate to the heat exchanger of a kind of both sides or employing microchannel, many sides Huo ∕ and thin passage.
Background technology
Although existing microchannel heat sink has good radiating effect, but due to the restriction of its version, yet have the following disadvantages: microchannel too long in flow, fluid flow resistance increases, wind effluent journey is too short, the utilizing status of wind is poor, increase accordingly blower fan power output, thus causes energy waste; Flow is difficult to increase, and is difficult to the heat exchange of formation scale; Be of limited application, heat exchange between liquid and liquid can not be done, be only limitted to gas and liquid or heat exchange between gas and gas.
Before this, Liu little Jiang has applied for an invention " a kind of cellular board fin heat exchanger of pure adverse current and assembly ", application number is: 201210029210.4, also apply for utility model " a kind of cellular board fin heat exchanger and assembly thereof " on the same day, application number is: 201220042482.3, this heat exchanger only has employing microchannel, side or thin passage, opposite side adopts and is suitable for away the fin configuration of gas 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, the heat exchange be only suitable between liquid and gas exchanges.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of heat transfer effect better, can save energy, and the heat exchanger of the wider both sides of the scope of application or employing microchannel, many sides Huo ∕ and thin passage.
The technical solution adopted for the present invention to solve the technical problems: the heat exchanger of a kind of both sides or employing microchannel, many sides Huo ∕ and thin passage, comprise the circulation carrying out exchange heat for different medium, it is characterized in that: described heat exchanger adopts pure countercurrent heat exchange method, described circulation is microchannel Huo ∕ and thin passage, alternating parallel arrangement in order, and have at least the import of side circulation and outlet to be located at the both sides of passage arranged in parallel respectively, described import is connected with respective channel by horizontal shunt conduit, described outlet is connected with respective channel by the channel that confluxes of transverse direction.
Further, the preferred 0.3-1mm of described microchannel diameter, the preferred 1-6mm of thin channel diameter.
Further, the transverse shape of described 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 determines the macroscopic property of molecule to a great extent, as when molecule does warm-up movement, intermolecular mutual collision is exactly a heating power transmittance process.In order to more effectively carry out heating power transmission, the present invention, by changing heat transfer fluid channels structure, all adopts microchannel Huo ∕ and thin passage, makes it more close to the length dimension of fluid molecule free path, thus improves heat exchange efficiency.Due to the raising of heat exchange efficiency, thus relatively can reduce size of heat exchanger, manufacturing cost is reduced, meanwhile, can avoid as existing microchannel too long in flow and cause the phenomenon that microchannel outlet section heat exchange efficiency is lower.
The present invention adopts pure countercurrent heat exchange method, has the advantage of countercurrent flow: not only mean temperature difference is maximum, and temperature gradient field and velocity field can be made to form minimum cosine angle, reaches good field coordination effect, thus improves the coefficient of heat transfer; In addition, side fluid outlet temperature can also be made as far as possible close to opposite side fluid inlet temperature, can temperature efficiency be improved.
Compared with prior art, the present invention can gather the passage that the microchannel of many suitable length flow processs or thin passage form a very big collection sectional area, for the heat exchange of scale; Applied widely, not only can be used for gas and liquid or heat exchange between gas and gas, also can be used for heat exchange between liquid and 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 can realize precursor in the flow direction after, and laggard person first goes out, and can optimize field coordination effect very well, makes cross sectional flow rate reach even, thus is conducive to heat exchange, and improve the coefficient of heat transfer; When fluid viscosity is comparatively large or fluid contains suspended particles, this fluid side adopts thin passage more suitable.
