Abstract

The invention discloses a heat exchanger, which comprises a first collecting pipe, a second collecting pipe separated from the first collecting pipe, heat exchange tubes and fins, wherein a refrigerant channel is arranged in each heat exchange tube; two ends of each heat exchange tube are respectively connected to the first and second collecting pipes so as to communicate with the first and second collecting pipes through the refrigerant channel; the whole cross section area of the refrigerant channel in the heat exchange tube changes along the flowing direction of the refrigerant in the heatexchange tube in order to keep the flowing speed of the refrigerant in the flowing direction thereof; and each fin is arranged between adjacent heat exchange tubes. In the heat exchanger of the embodiment of the invention, the whole cross section area of the heat exchange tubes at an inlet and outlet of the refrigerant changes following the state of the refrigerant and the flowing speed of the refrigerant in the heat exchange tube is kept even, so the whole efficiency of the heat exchanger is promoted and the heat exchange property of the heat exchanger can be better performed.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a heat exchanger. Background technique [0002] Traditional heat exchangers usually include headers, fins, and heat exchange tubes, in which the refrigerant flows inside the headers and heat exchange tubes, and the air flows on the outer surface of the heat exchanger, thereby realizing the separation between the refrigerant and the air. The heat exchange between them, and the heat exchange between the refrigerant and the air is enhanced through the fins. [0003] Although the heat transfer performance of the heat exchanger can be enhanced through the fins, the heat transfer performance of the conventional heat exchanger may be adversely affected by various factors, so further improvement is still needed. Contents of the invention [0004] The inventors of the present application have discovered that the change of the state of the refrigerant has an adverse effect on the ...
