Abstract

The invention provides a heat exchanger and a manufacturing method thereof, and relates to the technical field of heat exchange. The heat exchanger comprises fins and flat pipes; the fins are provided with mounting holes; each flat pipe comprises a pipe body and a reinforcing part, the pipe bodies are inserted into the mounting holes and connected with the fins in an expanded mode, the reinforcing parts are arranged in the pipe bodies and connected with the inner surfaces of the pipe bodies, and the reinforcing parts are configured to allow the pipe bodies to deform and limit the maximum deformation amount of the pipe bodies. The tube body of the flat tube is in expanded connection with the fins to fix the flat tube to the fins, so that the flat tube and the fins are fixedly connected without welding, the hydrophilicity of the hydrophilic layer of the fins is not affected, and the air volume of the heat exchanger and the heat exchange efficiency of the heat exchanger are prevented from being reduced. The reinforcing part in the pipe body can limit the maximum deformation amount of the pipe body, and the situation that the structural strength of the pipe body is affected due to excessive deformation of the pipe body in the pipe expanding process is avoided. And the reinforcing part can also play a role in reinforcing the structural strength of the tube body so as to prolong the service life of the flat tube and the heat exchanger.

Description

technical field [0001] The present application relates to the technical field of heat exchange, in particular, to a heat exchanger and a manufacturing method thereof. Background technique [0002] Finned heat exchangers are widely used due to their advantages of high heat exchange efficiency, compact structure and low manufacturing cost. However, the drainage performance of the flat tubes of the existing finned heat exchanger is poor, which affects the heat exchange performance of the heat exchanger. Contents of the invention [0003] Embodiments of the present application provide a heat exchanger and a manufacturing method thereof, so as to improve the problem of poor heat exchange performance of the heat exchanger. [0004] In the first aspect, the embodiment of the present application provides a heat exchanger, which includes fins and flat tubes; the fins are provided with installation holes; the flat tubes include a tube body and a reinforcing part, and the tube body ...
