Description

Technical Field

[0001] This utility model belongs to the field of engine cooler technology, specifically relating to an energy-saving gasoline engine cooling device. Background Technology

[0002] As the core power source of modern transportation and industrial equipment, the efficient and stable operation of gasoline engines relies on an effective cooling system. Traditional gasoline engine cooling devices mainly depend on radiators (water tanks) with fans to dissipate heat. This device removes the large amount of heat generated by the gasoline engine during operation through the circulation of coolant between the engine and the radiator, and then cools the engine through the airflow generated by the cooling fins on the radiator surface and the fan, thereby releasing the heat into the atmosphere and ensuring that the engine's operating temperature is maintained within a suitable range, as shown in publication number CN204024788. The existing patent of U discloses "an engine cooler, including an intercooler and a water-cooled radiator fixedly connected, the front sides of the intercooler and the water-cooled radiator are both windward sides for compressed air to be blown in, the windward sides of the intercooler and the water-cooled radiator are spaced apart on the left and right, the air-cooled box of the intercooler and the water tank of the water-cooled radiator are respectively equipped with a row of more than one heat pipe, each row of heat pipes is bridged and fixed by a row of heat dissipation fins arranged at intervals along the length of the heat pipe, the evaporation end of each heat pipe is sealed and inserted into the corresponding box, and the condensation end extends out of the corresponding box", which shows that the application describes a gasoline engine cooling device;

[0003] In existing gasoline engine cooling devices, the coolant inevitably carries impurities generated inside the engine, such as metal shavings and deposits, during circulation. If these impurities enter the radiator (water tank) directly without effective filtration, they will gradually accumulate in the pipes inside the water tank, forming scale or clogging the pipes. Once the pipes are blocked, the flow resistance of the coolant will increase significantly, leading to a decrease in the overall heat dissipation efficiency of the cooling system. When the heat dissipation efficiency is reduced, the external fan needs to operate at a higher speed and for a longer time to compensate for the insufficient heat dissipation, which further increases the energy consumption of the entire cooling system. Therefore, this utility model proposes an energy-saving gasoline engine cooling device. Utility Model Content
