Abstract

The invention provides a capillarity pipe heat exchanger. The capillarity pipe heat exchanger comprises multiple rows of capillarity pipes (1) and collecting pipes (2) located at the two ends of the capillarity pipes (1), wherein each row of capillarity pipes (1) comprise multiple capillarity pipes which are arranged at intervals and are supported and fixed by supporting blocks (3); the supportingblocks (3) extend in the distribution direction of each row of capillarity pipes (1); and the two ends of each supporting block (3) are fixed by side plates (4) arranged on the collecting pipes (2).The capillarity pipe heat exchanger can solve the problem in the prior art that the excessive large pipe diameter of a heat exchange pipe causes the reduction of the heat exchange efficiency of the heat exchanger and the relatively low utilization rate of refrigerants.

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...
