Abstract

The invention discloses a heat exchanger, which comprises a first collecting pipe, a second collecting pipe, a plurality of flat tubes and a plurality of groups of fins, wherein the first collecting pipe and the second collecting pipe are the same in axial directions and vertical directions; two ends of each flat tube are respectively connected with the first collecting pipe and the second collecting pipe, so that a refrigerant passage in the flat tube is respectively communicated with the first collecting pipe and the second collecting pipe, and each flat tube is not provided with a horizontal surface; the fins are provided with parts matched with the cross section shapes of the flat tubes, and are arranged at intervals along the length direction of the flat tubes. According to the heat exchanger of the embodiment of the invention, defrosted water of the heat exchanger cannot accumulate and stay on the surfaces of the flat tubes, but can flow along the surfaces of the flat tubes and drip onto the ground, so that a freezing problem of the flat tubes is avoided, the heat exchanger is enabled not to froze easily, the defrosting time of the heat exchanger is also shortened, frequent start of the defrosting mode of an air conditioner is avoided, and the low temperature heating effect and the working efficiency of the heat exchanger are improved.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a heat exchanger. Background technique [0002] In the prior art, the heat exchanger of the air conditioner, especially the heat exchanger used for the outdoor unit, is prone to icing or frosting, resulting in a decrease in the efficiency of the heat exchanger and inconvenience in use, so improvement is needed. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention needs to propose a heat exchanger that is not easy to freeze and frost, and has good heat exchange effect. [0004] The heat exchanger according to the embodiment of the present invention includes: first and second headers, the axial direction of the first and second headers is consistent with the vertical direction; a plurality of flat tubes, the flat tubes Both ends are respecti...
