One of the heat exchange media exchanges heat with the other heat exchange medium in the heat exchange space in the process of flowing in the heat exchange pipe, so that the heat exchange between the two heat exchange media is realized. The U-shaped heat exchange tube increases the flow path of the heat exchange medium, thereby improving the heat exchange effect between two heat exchange media.

When the flow rate of one of the heat exchange media is reduced relative to the flow rate of the other heat exchange medium, the heat exchange between the two can be promoted. Accordingly, when the flow rates of the two heat exchange media are too large, the heat exchange effect may be affected.
When the manager judges that the flow of the two heat exchange media needs to be adjusted, set values of the two flows are input to the data processing terminal, the data processing terminal further sends the set values of the two flows to the controller, and the controller controls the first valve and the second valve to act according to the control signal, so that the flow adjustment of the two heat exchange media is realized.
