Detailed description of the invention

This utility model patent is further described by the example shown in below in conjunction with the accompanying drawings.

Such as Fig. 1, shown in 2, this utility model patent provides the heat exchanger of a kind of porous microchannel section bar.Mainly include section bar (1), conduit (2), internal layer collector (3,4), outer layer collector (5,6), refrigerant inlet (7), refrigerant outlet (8), heat transferring medium entrance (9), heat transferring medium outlet (10).For every root type material, on circumference, cold-producing medium microchannel (11～18) number is 8, and internal heat medium channel (19) number is 1.2 fender brackets (20,21) it are provided with outside heat exchanger.

As shown in Figure 3, in the present embodiment, cold-producing medium is conveyed into heat exchanger by the entrance (7) on internal layer collector (3), the chamber of collector (3) directly connects with the cold-producing medium microchannel (11～18) of many root type material (1), and the heat exchanging medium passage (19) internal with section bar (1) does not connects.Heat transferring medium entrance (9) inflow heat exchanger on collector (5), the chamber of collector (5) is connected with the heat exchanging medium passage of section bar (1) by conduit (2), and does not connects with the cold-producing medium microchannel (11～18) of section bar (1).Conduit (2) plays the effect that the heat exchanging medium passage (19) making section bar (1) connects with outer layer collector (5,6).

Cold-producing medium enters internal layer collector (4) through the cold-producing medium microchannel (11～18) of section bar (1)；Meanwhile, heat transferring medium flows into outer layer collector (6) through the heat exchanging medium passage (19) of section bar (1).High Efficiency Thermal exchange between cold-producing medium and heat transferring medium occurs during two kinds of fluids flow in section bar (1) inner passage simultaneously, and two media flow direction in section bar (1) is contrary.After completing heat exchange, cold-producing medium is via outlet (8) outflow heat exchanger of collector (4)；Heat transferring medium is via outlet (10) outflow heat exchanger of collector (6).

Owing to heat exchanging medium passage is closed in heat exchanger, heat exchanger can select fluid that thermal capacitance is high as heat transferring medium, and is not limited to air and aqueous water, is conducive to expanding the range of choice of heat transferring medium, improves heat exchange efficiency.The heat transferring medium of inflow heat exchanger is in stable condition controlled, and the design for heat exchange control system is provided convenience.Heat transferring medium is in use closed in pipe-line system, will not be polluted by impurity.Heat exchanger pipeline system itself will not be conducive to improving the service life of heat exchanger because heat transferring medium is by corrosion failure.Owing to profile design make use of microchannel enhanced heat exchange mechanism, whole heat exchanger size is little, lightweight, compact conformation, can be applicable to narrow space and the occasion of environmental condition harshness.

The purpose of above-described embodiment is to illustrate design and the feature of this utility model patent, is to allow professional will appreciate that the content of this utility model patent and to implement according to this, without limiting the protection domain of this utility model patent.All equivalence changes done according to this utility model patent statement essence, within all should being included in the protection domain of this utility model patent.
