Abstract
The utility model discloses a kind of micro-channel heat exchanger, comprise by upper and lower collector and be placed in the heat exchanger body that many flat tubes being communicated with between described upper and lower collector and with it and arranging and fin form, on the right side of described upper header He on the left of lower collector pipe, offering refrigerant inlet and refrigerant outlet respectively; Between described upper and lower collector, perpendicular separation is provided with 56 flat tubes, from right to left between the 25 to 26 flat tube position upper header in be provided with upper spacer, from left to right between the 12 to 13 flat tube position lower collector pipe in be provided with lower clapboard; Described flat tube is porous flat pipe, is of a size of 25.4 × 1.3mm, and described fin is of a size of 25.4 × 8mm.The utility model advantage is that structure is simple, and result of use is good.Cold-producing medium is able to abundant cycle heat exchange, and cold-producing medium can save 20%, and indoor/outdoor temperature-difference is promoted to 9 DEG C by original 7 DEG C.
Description
Technical field
The utility model relates to air conditioner for vehicle, especially relates to a kind of micro-channel heat exchanger.
Background technology
Operationally, heat exchange temperature skewness, speed and the amplitude of cooling are less, and its infrastructure cost is compared with high, large by doses for current air conditioning for automobiles.Flat tube uses 25 × 1.3mm, and fin uses specification to be 25 × 6mm, easily blocks fin, affects its heat transfer effect.
Summary of the invention
The utility model object is to provide a kind of uniformity of temperature profile, heat exchange efficiency efficient micro-channel heat exchanger.
For achieving the above object, the utility model can take following technical proposals:
Micro-channel heat exchanger described in the utility model, comprise by upper and lower collector and be placed in the heat exchanger body that many flat tubes being communicated with between described upper and lower collector and with it and arranging and fin form, on the right side of described upper header He on the left of lower collector pipe, offering refrigerant inlet and refrigerant outlet respectively; Between described upper and lower collector, perpendicular separation is provided with 56 flat tubes, from right to left between the 25 to 26 flat tube position upper header in be provided with upper spacer, from left to right between the 12 to 13 flat tube position lower collector pipe in be provided with lower clapboard; Described flat tube is porous flat pipe, is of a size of 25.4 × 1.3mm, and described fin is of a size of 25.4 × 8mm.
The utility model advantage is that structure is simple, and result of use is good.By upper and lower dividing plate, the flow process of pipeline is changed to 25-19-12 by original 30-22-14, there will not be short circulating phenomenon, cold-producing medium is allowed to be able to abundant cycle heat exchange, flat tube is replaced by 25.4 × 1.3mm high-efficiency multiple flat tube, fin is replaced by the 25.4 × 8mm fin being easier to pass through, cold-producing medium can save 20%, and indoor/outdoor temperature-difference is promoted to 9 DEG C by original 7 DEG C.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, micro-channel heat exchanger described in the utility model, comprise by upper and lower collector 1,2 and to be placed between described upper and lower collector 1,2 and to be communicated with the heat exchanger body that the many flat tubes 3 that arrange and fin 4 form with it, on the right side of described upper header 1 He on the left of lower collector pipe 2, offering refrigerant inlet 5 and refrigerant outlet 6 respectively; Between described upper and lower collector 1,2, perpendicular separation is provided with 56 flat tubes 3, from right to left between the 25 to 26 flat tube 3 position upper header 1 in be provided with upper spacer 7, from left to right between the 12 to 13 flat tube 3 position lower collector pipe 2 in be provided with lower clapboard 8; Described flat tube 3 is porous flat pipe, is of a size of 25.4 × 1.3mm, and described fin 4 is of a size of 25.4 × 8mm.
