Description

Technical Field

[0001] The utility model relates to the technical field of automotive air - conditioning heat exchange, and specifically, to a connection structure of a variety of partition plates and a liquid collecting pipe. Background Art

[0002] Common existing outdoor heat exchangers for vehicles have the functions of both a condenser and an evaporator. The outdoor heat exchanger is generally installed in the front compartment of the vehicle and mostly borrows the design structure of the traditional condenser. However, when the outdoor heat exchanger is used in the evaporation mode, it often shows insufficient heat exchange capacity. On the basis of keeping the micro - channel heat dissipation tubes and louver heat dissipation belts unchanged, how to improve the heat exchange capacity in the evaporation mode has become a bottleneck for the outdoor heat exchanger. The design of the partition plate with flow - through holes effectively improves the flow distribution in each micro - channel heat dissipation tube and greatly increases the heat exchange capacity in the evaporation mode. For the micro - channel heat dissipation tubes and louver heat dissipation belts, the traditional design can still be borrowed without modification. The design of the partition plate with flow - through holes is simple and has a low manufacturing cost, with small investment and large return for improving the heat exchange capacity in the evaporation mode.
