The second inlet pipe 16 is connected to the filter device 9 and is used to circulate the cooled water back into the system. The three-phase output wire 7 is connected to the filter device 9 and is run between the second outlet pipe 15 and the second inlet pipe 16, thus forming a compact pipeline layout and saving internal space.

[0028] The heat exchange device 10 includes a heat exchange housing 17, inside which a heat exchange chamber 18 is provided. A heat exchange section 19 is located within the heat exchange chamber 18, and this section 19 is composed of multiple overlapping and tightly joined heat transfer plates 20 to maximize heat transfer efficiency. The first inlet 11 and the first outlet 14 of the heat exchange device 10 communicate with the heat exchange chamber 18 for the entry and exit of external cold water. The second outlet 12 and the second inlet 13 communicate with the heat exchange section 19 for the circulation of coolant. A fixed back plate 21 is provided at the rear end of the heat exchange device 10, which is directly mounted and fixed to the generator body 3.

[0032] When this utility model is in use, the generator body 3 is first started. The diesel engine 34 converts chemical energy into mechanical energy and drives the entire power system through the crankshaft 30. The input end of the crankshaft 30 is connected to the flywheel rotor 32. As the crankshaft 30 rotates, the flywheel rotor 32 rotates accordingly. The magnetic tiles 33 set on its inner wall form a strong rotating magnetic field on the outer periphery of the stator 31, thereby enabling the stator 31 to efficiently convert mechanical energy into electrical energy through electromagnetic induction, realizing the power generation function. During the continuous and efficient operation of the generator body 3, a large amount of heat will inevitably be generated. The coolant first absorbs the heat inside the machine body and flows into the filter device 9. After being powered on, the filter device 9 can purify the coolant, removing impurities or harmful components. Subsequently, it enters the heat exchange section 19 in the heat exchange device 10 through the second water inlet pipe 16, where it exchanges heat with the external cold water from the first water inlet pipe 5 in the heat exchange chamber 18. After completing the cooling process, the coolant flows back to the generator body 3 through the second water outlet pipe 15 to continue participating in the circulating cooling.
