It is an industrial application of convective heat transfer and heat conduction. Heat exchangers can be classified in different ways. According to their operating processes, they can be divided into three categories: shell-and-tube type, mixed type, and regenerative or recuperative type; according to the compactness of their surfaces, they can be divided into compact and non-compact types.

[0003] For example, a combined heat exchanger with the publication number CN202221441781.4 includes a heat exchanger body and a base plate. A refrigerant inlet pipe is provided on the left side of the heat exchanger body, a heat medium inlet pipe is provided on the right side of the heat exchanger body, a refrigerant outlet pipe is provided on the upper left side of the heat exchanger body, a heat medium outlet pipe is provided on the upper right side of the heat exchanger body. Mounting plates are provided on both the left and right sides at the lower end of the heat exchanger body. A moving mechanism is provided on the upper end of the base plate, and an adjusting mechanism is provided on the upper end of the moving mechanism. By rotating the turntable to rotate the screw in the square cavity, the two convex blocks with opposite threads can slide synchronously in the same or opposite directions. At the same time, a moving plate is slidably connected to the upper end of the base plate, and the convex parts of the convex blocks penetrate through the square cavity to connect the moving plate, so that the moving plate can be slidably adjusted, and thus it is convenient to adjust and assemble the position of the mounting plate according to heat exchanger body equipment of different models.
