Abstract

The invention provides a heat exchanger. The heat exchanger comprises a first row of heat exchanger and a second row of heat exchanger which are arranged side by side; and the first row of the heat exchanger comprises fins and the second row of the heat exchanger comprises fins. The density of the fins of the first row of the heat exchanger is different from that of the fins of the second row of the heat exchanger. The different densities of the fins are set according to different layer numbers, so that the frost formation of a micro channel heat exchanger can be reduced, and the capacity of the running of a system and the efficiency are improved.

Description

technical field [0001] The invention relates to a heat exchanger. Background technique [0002] refer to Figure 1A , 1B , 1C, the heat exchanger 10' such as a microchannel heat exchanger includes: a first row of heat exchangers R1 and a second row of heat exchangers R2. The heat exchanger 10' also includes: a header 11 at the inlet end of the heat exchanger and a header 12 at the outlet end of the heat exchanger, which are respectively connected to the header 11 at the inlet end of the heat exchanger and the header 12 at the outlet end of the heat exchanger The heat exchanger inlet pipe 21 and the heat exchanger outlet pipe 22, as well as the intermediate connection pipe 23 of the heat exchanger. [0003] Such as Figure 1A As shown, the refrigerant flows in the direction R, and the wind blows in the direction A to the heat exchanger 10'. Both the first row of heat exchangers R1 and the second row of heat exchangers R2 include heat exchange tubes 14 such as flat tubes an...
