The heat conduction medium of the water temperature machine is water. Under the condition of regulating the temperature, the heat conduction effect of the media of the water temperature machine is better. Under normal atmospheric pressure, the boiling point of water is 100℃, in the case of no pressure, the control temperature of the water temperature machine can only be less than or equal to 100℃. In practical application, by increasing the pipeline pressure, the temperature control temperature of the water temperature machine can be raised to 180℃, thus expanding the application range of the water temperature machine.
