Its main features are compact structure, high thermal efficiency, large heat transfer area, low resistance, and easy operation. Combined heat exchangers are widely used in chemical, petroleum, metallurgy, electric power, light industry and other fields, meeting the heat exchange needs under various working conditions. In order to improve the heat conversion efficiency, a combined heat exchanger is needed. However, existing combined heat exchangers still have the following shortcomings:

[0003] For example, the utility model with application number 201820804907.7 discloses a combined heat exchanger. The combined heat exchanger described in the utility model has a multi-purpose function of one machine, which can heat up or cool down the fluid as needed, and the heating and cooling both use the same water tank.
