Embodiment 1

[0033] This preferred embodiment discloses a microchannel heat exchanger. like figure 1 and figure 2 As shown, the microchannel heat exchanger includes a left header 11, a right header 12, a plurality of flat tubes 2 communicated between the left header 11 and the right header 12, and a plurality of flat tubes stuck between the left header 11 and the right header 12. fins 3 between tubes 2. A first spacer 41 is inserted in the left header 11, and the left header 11 is divided into upper and lower parts. 54 communicates with the lower cavity of the left header 11. A fourth partition 44 is inserted in the right collector 12 to divide the right collector 12 into upper and lower parts. The fourth partition 44 is provided with a through hole connecting the upper part and the lower part of the right collector 12 .

[0034] In this structure, the refrigerant can be injected into the upper part or the lower part of the right collector 12 through the through hole, the spraying dis...

Abstract

The invention discloses a micro-channel heat exchanger and an air conditioner, and belongs to the field of air conditioners and accessories of the air conditioners. The micro-channel heat exchanger and the air conditioner are designed for solving the problem that a refrigerating agent is distributed unevenly in an existing device. The micro-channel heat exchanger comprises a left collecting pipe, a right collecting pipe, multiple flat pipes communicated between the left collecting pipe and the right collecting pipe and fins clamped between the flat pipes. A first separation sheet is inserted in the left collecting pipe and divides the left collecting pipe into an upper part and a lower part, a first connecting pipe is communicated to the upper part of the left collecting pipe, and a fourth connecting pipe is communicated to the lower part of the left collecting pipe. A fourth separation sheet is inserted in the right collecting pipe and divides the right collecting pipe into an upper part and a lower part, and a through hole through which the upper part and the lower part of the right collecting pipe are communicated is formed in the fourth separation sheet. The air conditioner comprises an outdoor unit which comprises the micro-channel heat exchanger. By the adoption of the micro-channel heat exchanger and the air conditioner, the problem that the refrigerating agent is distributed unevenly is solved, so that the heat exchange performance of the heat exchanger is improved.

Description

technical field [0001] The invention relates to the field of air conditioners and accessories thereof, in particular to a microchannel heat exchanger and an air conditioner equipped with the microchannel heat exchanger. Background technique [0002] The microchannel heat exchanger is a device used in the condenser of the outdoor unit of the household air conditioner or automobile air conditioner. The refrigerant flows between the header and the flat tube, and the air passes through the fins, and the refrigerant exchanges heat with the air. . [0003] When the refrigerant used is a gas-liquid two-phase refrigerant and the header is placed vertically, the gas-liquid two-phase refrigerant will have a certain degree of gas-liquid stratification and uneven distribution due to the action of gravity. Among them, the gaseous refrigerant is easy to gather In the upper part of the collector cavity, the liquid refrigerant is easy to accumulate in the lower part of the collector cavity...
