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 heat exchange 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, and in particular to a heat exchanger. Background technique [0002] Traditional heat exchangers usually include headers, fins, and heat exchange tubes. The refrigerant flows inside the headers and heat exchange tubes, and the air flows on the outer surface of the heat exchanger, thereby realizing refrigerant and air The heat exchange between the refrigerant and the air is enhanced by the fins. [0003] Although the heat exchange performance of the heat exchanger can be enhanced by the fins, the heat exchange performance of the traditional heat exchanger may be adversely affected by many factors, so further improvement is still needed. Summary of the invention [0004] The inventor of the present application has discovered that the change of the refrigerant state has an adverse effect on the heat exchange performance. In the heat exchanger, the refrigerant undergoes a state change through heat exc...
