Abstract

The invention provides an engine cooling system and a filtering device thereof. The engine cooling system can automatically open and close a cooling liquid inlet according to a work state of an engine to prevent cooling water from flowing outwards in a process of replacing cooling water of a filter, avoids environmental pollution and waste and saves cost. The filtering device comprises a filter seat and a cooling liquid filter and further comprises a pressure valve, wherein the filter seat is provided with a cooling liquid inlet and a cooling liquid outlet, the cooling liquid filter is arranged on the filter seat, and the pressure valve can be opened under the push of the high-pressure cooling liquid to plug the cooling liquid inlet and the cooling liquid outlet after the pressure is released. When the engine works, water output by a water pump can generate pressure to push the pressure valve, and the pressure valve can be opened to open the cooling liquid inlet and the cooling liquid outlet.

Description

technical field [0001] The invention relates to the technical field of engine cooling, in particular to a filter device for an engine cooling system. The present invention also relates to an engine cooling system with the filter device described above. Background technique [0002] The coolant filter is used to filter impurities in the engine coolant, and it can also add chemical components to the engine cooling system to improve the engine's coolant performance. After a period of use, the coolant filter needs to be replaced to ensure its reliability. [0003] The filter device in the prior art is usually not equipped with any device. When the coolant filter is replaced, the coolant inlet is in an open state, and the coolant is easy to flow out, causing pollution and waste. [0004] Please refer to figure 1 with figure 2 , figure 1 It is a structural schematic diagram of a filter device of an engine cooling system in a specific embodiment in the prior art; figure 2 I...
