Embodiment Construction

[0017] The principle and specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0018] figure 1 , image 3 It is a structural schematic diagram of a micro-channel aluminum strip tube heat pump type air conditioner heat exchanger. The heat exchanger consists of an upper header 1, a lower header 2, a connecting pipe 3 arranged in parallel between the upper and lower headers, and a connecting pipe 4, the connecting pipe and the connecting pipe adopt the microchannel aluminum strip pipe with ribs 5, and the connecting pipe 3 is provided with two or more, two of which are respectively arranged at the two ends of the lower header, each The root connecting pipe is directly connected with the upper header and the lower header (such as Figure 5 shown); the upper end of the connecting pipe 4 is directly communicated with the upper header 1, and the lower end is communicated with the lower header 2 and penetrat...

Abstract

This invention relates to a micro-channel ribbon tube hot pump air-condition / exchanger composed of an upper collector, a lower collector, micro-channel ribbon tubes and ribs, which are plane or wave ones with drainage grooves distributed slantly against the wind to exhaust condensed water or frost water timely, in which a liquid separation structure is applied for the connection of upper and lower collectors with the micro-channel ribbon tubes to solve the problem that heat-exchange area can't be used fully since cooling agent can't flow uniformly among channels when the heat exchanger is used as an evaporator.

Description

technical field [0001] The invention relates to an air-cooled heat exchanger for air-conditioning, in particular to a micro-channel aluminum strip tube type air-conditioning heat exchanger, which belongs to the technical field of air-conditioning equipment. Background technique [0002] Most existing air conditioners use finned tube heat exchangers. With the current rise in copper prices, the production cost of existing air conditioners has been greatly increased, and it is urgent to adopt new enhanced heat transfer technology to reduce costs and achieve the purpose of energy saving. In recent years, micro-scale heat transfer technology has developed rapidly, and the micro-multi-channel aluminum strip tube heat exchanger, as a new type of heat exchanger, is being widely used in the field of automotive air conditioning. Utility model patent (200510012007.6) discloses a transcritical CO 2 Circulating micro-channel parallel flow heat exchanger and method of manufacture, but i...
