Embodiment Construction
[0014] The principle and structure of the present invention will be described in detail below in conjunction with the drawings and embodiments.
[0015] Such as figure 1 As shown, the microchannel heat exchanger proposed in the present invention includes several heat exchange units, and the heat exchange unit includes a horizontally arranged liquid header, an obliquely arranged air header, and several heat exchangers arranged between the liquid header and the air header One heat exchange tube, the heat exchange tube connects the liquid collection pipe and the air collection pipe, the air collection pipe is located above or below the liquid collection pipe, one end of the liquid collection pipe is the refrigerant inlet end, the other end is the closed end, the upper end of the first air collection pipe is Refrigerant outlet port.
[0016] In this embodiment, there are two heat exchange units, namely the first heat exchange unit 10 and the second heat exchange unit 20 , and the...

The invention discloses a micro-channel heat exchanger and an air conditioner. The micro-channel heat exchanger comprises a plurality of heat exchange units, each heat exchange unit comprises a liquidcollecting pipe, a gas collecting pipe and a plurality of heat exchange pipes, the heat exchange pipes are used for communicating the liquid collecting pipes and the gas collecting pipes, the gas collecting pipes are located above or below the liquid collecting pipes, one end of each liquid collecting pipe is a refrigerant inlet end, and the other end of each liquid collecting pipe is a closed end. At least two heat exchange pipes are vertically arranged, every two adjacent heat exchange pipes are parallel, the length of each heat exchange pipe from the refrigerant inlet end of the liquid collecting pipe to the closed end of the liquid collecting pipe is gradually smaller or gradually increased, fins are arranged between every two adjacent heat exchange pipes. The invention further provides an air conditioner which comprises the micro-channel heat exchanger in any one of the above. Compared with the prior art, the heat exchanger ensures that the liquid refrigerant entering the heat exchange units can be accumulated in the heat exchanger and can not flow out of the heat exchanger without being vaporized, so that the refrigerant flowing out from the refrigerant outlet is a gaseous refrigerant.
Description
technical field [0001] The invention relates to the technical field of air conditioning, in particular to a microchannel heat exchanger and an air conditioner. Background technique [0002] Microchannel heat exchanger is a new type of high-efficiency heat exchanger, which has the advantages of high heat transfer efficiency, small size, light weight, and less charge. It has been widely used in outdoor single coolers. [0003] However, the existing microchannel heat exchangers have the following problems: when the heat that can be taken away by the air side is greater than the heat required for the liquid refrigerant to be completely vaporized into a gaseous refrigerant, that is, when the liquid refrigerant in the heat exchanger cannot be completely vaporized into a gaseous refrigerant , liquid refrigerant may flow out from the refrigerant outlet. Contents of the invention [0004] In order to solve the problem in the prior art that the liquid refrigerant flows out from the...
