Description

Technical Field

[0001] The present invention particularly relates to a heat exchanger structure and a method of using the same. Background Art

[0002] A heat exchanger is a device used to transfer heat between two or more fluids. It is often used in industrial applications where heat needs to be transferred from one fluid to another. Its main function is to improve energy efficiency, reduce energy consumption, and improve the overall performance of the system. The application of heat exchangers in electric vehicles is very critical. Common heat exchangers include battery thermal management, air conditioning systems, drive motor cooling, and many other aspects.

[0003] Existing heat exchangers are usually welded with connecting pipes to facilitate docking with external pipes during fluid transportation. However, after welding, the direction of the connecting pipes is not easy to adjust, and they cannot be docked with external pipes in any direction. They are also not easy to disassemble and maintain. After the connecting pipes leak, it is relatively troublesome and time-consuming to maintain them, and the use effect is not good. For this reason, we propose a heat exchanger structure and a method for using the same. Summary of the invention
