Embodiment Construction

[0016] Such as figure 1 and figure 2 As shown, a kind of automobile heat pump air conditioner adopting the insert type microchannel heat exchanger of the present invention includes the insert type microchannel heat exchanger, and the insert type microchannel heat exchanger includes flat tubes 2 and fins 1, and the Both ends of the flat tube 2 are provided with headers 3 , and the fin 1 is provided with a flat tube groove 11 , and the flat tube 2 is inserted into the flat tube groove 11 of the fin 1 .

[0017] Such as figure 2 As shown, the flat tubes 2 of this embodiment are arranged horizontally, and the fins 1 are arranged vertically. A wing 12 is provided on one side of the flat tube groove 11 on the fin 1 , and the width of the wing 12 is 1 / 5-1 / 3 of the width of the flat tube 2 . In addition, in order to conduct water better when it rains, the wing edge 12 is provided with a water guide line 13, so that the water flow will not flow to core components such as flat tube...

Abstract

The invention relates to the technical field of automobile heat pump air conditioners, in particular to an automobile heat pump air conditioner adopting a patch type micro-channel heat exchanger. Theautomobile heat pump air conditioner adopting a patch type micro-channel heat exchanger comprises a patch type micro-channel heat exchanger, wherein the patch type micro-channel heat exchanger comprises flat tubes and fins; headers are arranged at two ends of the flat tubes; flat tube grooves are formed in the fins; and the flat tubes are inserted into the flat tube grooves of the fins. After thestructure is adopted, the refrigerant filling amount of the invention is small, and when the patch type micro-channel is used as the condenser, the micro-channel heat exchanger can play a role of high-efficiency heat exchange of the condenser; when the patch type micro-channel heat exchanger is used as an evaporator, wing edges can well drain water, reduce wind resistance, reduce thermal resistance and improve heat exchange; and under frosting conditions, the wing edges can well increase frosting time and delay frosting.

Description

technical field [0001] The invention relates to the technical field of automobile heat pump air conditioners, in particular to an automobile heat pump air conditioner using an insert type micro-channel heat exchanger. Background technique [0002] The existing microchannel heat exchanger includes flat tubes, headers and fins. The flat tubes are inserted into the headers, and the fins are wave-shaped, sandwiched between the flat tubes, and welded in a furnace. The width of the fins is equal to that of the flat tube. When used as an evaporator, the water is not easy to flow out, resulting in the loss of flying water and air volume. In the case of frosting, the space for frosting is small, and it takes about half an hour to defrost. The heating effect is poor. Therefore, some automotive heat pump air conditioner manufacturers switch to copper tubes and aluminum fins as heat exchangers, which can ensure the outflow of condensed water and the frosting cycle. However, the weight...
