When the engine water temperature is low, the thermostat is not opened. The engine coolant is driven by a water pump on the engine water inlet side, so that the coolant only passes through the engine and the small-circulation cooling pipe and then flows back to the engine, realizing the cooling function while reducing the coolant flow.
[0010] Preferably, switch valves are installed at both ends of the small-circulation cooling pipe to control the opening or closing of the small-circulation cooling pipe; in use, when the engine water temperature is low, the thermostat is not opened. The engine coolant is driven by a water pump on the engine water inlet side, so that the coolant only passes through the engine and the small-circulation cooling pipe and then flows back to the engine, realizing the cooling function while reducing the coolant flow; when the engine water temperature is high, the thermostat is opened, and the engine coolant flows through the radiator and the cooling circulation pipe and then flows to the engine. At this time, the small-circulation cooling pipe is in a closed state.

[0019] An expansion water tank 6 arranged on one side of the cooling system. The cooling system includes an engine 1, a thermostat 2, a radiator 3, and a cooling circulation pipe 4. The radiator 3, the engine 1, and the thermostat 2 are connected through the cooling circulation pipe 4 so that a cooling circulation can be formed between them. The expansion water tank 6 is connected to the radiator 3 through an exhaust pipe 1, so that the radiator 3, the cooling circulation pipe 4, and the exhaust pipe 1 are connected in communication, shortening the length of the exhaust pipe. An expansion water tank 8 is arranged on one side of the engine 1, making the distance between the expansion water tank 8 and the engine 1 closer, shortening the length of the improved exhaust pipe 9 therebetween, improving the degassing ability of the cooling system, and preventing the engine 1 water temperature alarm caused by poor degassing.
[0020] Refer to Figure 2 As shown, the expansion water tank 8, the engine 1, and the thermostat 2 are connected through an improved exhaust pipe 9, that is, another set of expansion water tanks 8 is provided on one side of the engine 1, shortening the length of the improved exhaust pipe 9.
[0021] Refer to Figure 2 As shown, the heights of the expansion water tank 6 and the expansion water tank 8 are higher than the height of the engine 1, improving the coolant filling, making the filling easier and shortening the filling time.
[0022] Refer to Figure 2 As shown, the cooling system further includes a small circulation cooling pipe 5. A small circulation cooling pipe 5 is connected to one side of the engine 1. When the water temperature of the engine 1 is low, the set thermostat 2 is not opened, and the coolant of the engine 1 is driven by the water pump on the water inlet side of the engine 1, so that the coolant only passes through the engine 1 and the small circulation cooling pipe 5 and then returns to the engine 1, realizing the cooling effect while reducing the coolant flow.
[0023] Refer to Figure 2As shown, switch valves are installed at both ends of the small circulation cooling pipe 5 to control the opening or closing of the small circulation cooling pipe 5. During use, when the water temperature of the engine 1 is low, the thermostat 2 provided does not open, and the coolant of the engine 1 is driven by the water pump on the water inlet side of the engine 1, so that the coolant only passes through the engine 1 and the small circulation cooling pipe 5 and then flows back to the engine 1, realizing the cooling effect while reducing the coolant flow. When the water temperature of the engine 1 is high, the thermostat 2 provided opens, and the coolant of the engine 1 flows through the radiator 3 and the cooling circulation pipe 4 and then flows to the engine 1. At this time, the small circulation cooling pipe 5 is in a closed state.
[0024] In the present utility model, a set of expansion water tank two 8 is provided on one side of the engine, so that the expansion water tank two 8 is closer to the engine 1, shortening the length of the improved exhaust pipe 9 therebetween. The improved exhaust pipe 9 is connected upward to the expansion water tank two 8, which is beneficial to improving the coolant filling efficiency on the engine body side, making filling easier and shortening the filling time. It can improve the coolant degassing efficiency during the engine coolant filling process and during the engine operation, ensure the air ratio inside the engine cooling water jacket and the entire cooling water pipe, meet the design requirements, improve the vehicle use convenience, and is beneficial to use.
