Refer to Figure 1 、 Figure 2 and Figure 5As shown in the figure, the movable internal combustion engine water system circulating preheating device includes a movable support device 1, on which an electric heating device 2 and a water flow power device 3 are arranged.

[0031] The electric heating device 2 is connected with a water outlet pipe 5 and a water return pipe 6, and the water flow power device 3 is arranged on the water return pipe 6.

[0032] During installation, the staff moves the movable internal combustion engine water system circulating preheating device to the internal combustion engine vehicle, connects the water outlet pipe 5 to the water inlet of the vehicle water system, and connects the water return pipe 6 to the water drain of the vehicle water system.

[0033] By adopting the movable support device, the overall movement of the preheating device can be realized, which is convenient for preheating operation and applicable to different internal combustion engine vehicles.

[0034] When in use, the water flow power device 3 is started to provide water flow power.
