Problems solved by technology

However, in actual use, due to the small diameter of the microchannel tube 201, after the condensed water forms on the microchannel tube 201, its viscous force is equivalent to gravity, and the condensed water is not easy to get rid of. The accumulation will increase the heat transfer resistance, which will reduce the heat transfer performance of the micro-channel tube heat exchanger

Abstract

The invention provides a micro-channel heat exchanger and an air conditioner. The micro-channel heat exchanger comprises an inlet tube, an outlet tube, a flow collection tube and a plurality of micro-channel tubes, wherein the inlet tube and the outlet tube form an inlet-outlet tube group; the plurality of micro-channel tubes are located between the flow collection tube and the inlet-outlet tube group; the micro-channel tubes connected with the inlet tube are arranged slantwise and downwards along a direction from the inlet tube to the flow collection tube; and the micro-channel tubes connected with the outlet tube are arranged slantwise and downwards along a direction from the flow collection tube to the outlet tube. The purpose of rapidly draining condensed water by the micro-channel heat exchanger is realized, the drainage performance is improved, and the heat exchange performance is enhanced, so as to further improve the energy efficiency of the air conditioner.

Description

technical field [0001] The invention relates to the technical field of heat pumps, in particular to an air conditioner outdoor unit, a microchannel heat exchanger and an air conditioner. Background technique [0002] At present, air conditioners are easy to install, use and manage, have multiple cooling and heating functions, and can be flexibly selected. They have broad market prospects and are adopted by more and more families, offices and businesses. The heat exchanger in the air conditioner is an important component, and the heat exchanger is divided into a finned heat exchanger and a micro-channel heat exchanger according to the structure. Such as figure 1 As shown, the microchannel heat exchanger generally includes an inlet pipe 101, an outlet pipe 102, a header 103 and a plurality of microchannel pipes 201, wherein the inlet pipe 101 and the outlet pipe 102 form an inlet and outlet pipe group, and a plurality of microchannel pipes 201 is located between the header 1...
