Abstract

The invention provides a capillary heat exchanger. The capillary heat exchanger includes multiple rows of capillary tubes (1) and headers (2) located at both ends of the capillary tubes (1), each row of capillary tubes (1) includes a plurality of capillary tubes (1) arranged at intervals, each row of capillary tubes (1) The support blocks (3) between them are supported and fixed, and the support blocks (3) extend along the arrangement direction of each row of capillary tubes (1), and the two ends of the support blocks (3) pass through the side plates arranged on the headers (2) (4) Fixed. According to the capillary heat exchanger of the present invention, the problems in the prior art that the heat exchange efficiency of the heat exchanger is reduced and the utilization rate of the refrigerant is low caused by the excessively large diameter of the heat exchange tube can be solved.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a capillary heat exchanger. Background technique [0002] The traditional tube-fin heat exchanger includes heat exchange tubes, fins, and headers located at both ends of the heat exchange tubes. Multiple heat exchange tubes are arranged in parallel, and the two ends of each heat exchange tube are respectively connected to the collectors at both ends. On the flow tubes, the heat exchange tubes are installed on the fins, and the heat dissipation area is increased through the fins to improve the heat exchange efficiency of the tube-fin heat exchanger. However, the diameter of the heat exchange tubes of the tube-fin heat exchanger is relatively large, which is not only high in cost, but also takes up a large volume, and the refrigerant located in the middle of the heat exchange tubes of the tube-fin heat exchanger is far away from the edge of the heat exchange tubes. Heat ex...
