[0002] A diesel water-cooled engine is a type of engine that uses a coolant for heat dissipation, mainly used for high-power diesel engines. In cold regions, before starting a diesel water-cooled engine, it is necessary to first heat the lubricating oil inside the engine. The lubricating oil inside the engine block is relatively viscous at low temperatures and cannot normally perform its lubricating function. The engine is connected to a water tank, and the temperature of the coolant in the water tank needs to be heated to 40°C - 70°C before the engine can start normally and safely. If forced to start in a low-temperature area, it will damage the internal cylinder block of the engine and reduce its service life.

[0021] Above the heat exchanger 501, a water outlet pipe 3 is provided. One end of the water outlet pipe 3 extends into the interior of the heat exchanger 501 and is connected to one end of a rotary joint pipe 402. The water outlet pipe 3 is a spiral pipe inside the heat exchanger 501. The other end of the water outlet pipe 3 passes through the protective plate 2 and is connected to the engine water tank. One end of a water pump 401 is provided with a water inlet pipe 4. The other end of the water pump 401 is connected to one end of the rotary joint pipe 402.
