Abstract

The invention discloses a heat exchanger used for a refrigerator and a manufacturing method of the heat exchanger. The heat exchanger used for the refrigerator comprises a heat exchange tube and a plurality of fins, wherein the fins are arranged on the heat exchange tube at intervals; each fin is provided with a mounting part and a plurality of fan-shaped blades; the fan-shaped blades are connected with the mounting part and are arranged at intervals along the circumferential direction of the mounting part; the mounting part is provided with an axial mounting hole; the heat exchange tube passes through the axial mounting hole and is matched inside the axial mounting hole so that the fins are arranged on the heat exchange tube. The heat exchanger used for the refrigerator according to the embodiment of the invention has the advantages of being high in heat exchange efficiency, small in frost quantity, easy to defrost, and the like.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a heat exchanger for a refrigerator and a manufacturing method of the heat exchanger. Background technique [0002] The fins of the existing heat exchanger are all rectangular plates. The fins of this shape have a large area, which will cause a large amount of frosting on the fins, thereby making the heat exchange efficiency of the heat exchanger low and making defrosting difficult. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present invention is to provide a heat exchanger for a refrigerator which has the advantages of high heat exchange efficiency, small amount of frosting, and easy defrosting. [0004] Another object of the present invention is to propose a manufacturing method of the heat exchanger. [0005] The heat exchanger for a refrigerator acc...
