Thermostat assembly, cooling system, engine and car

Abstract

The present disclosure provides a thermostat assembly, a cooling system, an engine, and an automobile. The thermostat assembly includes: a thermostat housing having a first inner chamber, a second inner chamber and communicating with the first inner chamber and The shut-off channel of the second inner cavity, the thermostat housing has a first opening, a second opening, a third opening and a fourth opening, the first opening and the second opening are both connected to the first inner cavity, and the third opening is connected to the second inner cavity The two inner chambers communicate, the fourth opening communicates with the first inner chamber and the second inner chamber at the same time, the first opening communicates with the radiator, the second opening communicates with the cylinder water jacket, and the third opening communicates with the automobile The heater is connected, and the fourth opening is used to communicate with the water jacket of the cylinder head; the thermostat is connected with the thermostat housing and is located at the first opening, and is used to control the on-off of the first opening. The present disclosure can adopt a single thermostat to configure the coolant flowing out of the water jacket of the cylinder block and the water jacket of the cylinder head, thereby reducing the energy consumption and cost of the engine.

Description

Technical field [0001] The present disclosure relates to the field of automotive technology, and more particularly to a thermostat assembly, a cooling system, an engine, and a car. Background technique [0002] The cooling system of the engine is an important part of the engine. The main function of the cooling system is to exude part of the heat generated in the engine to ensure that the engine can operate in a suitable temperature. The cooling system includes an engine pump, a cylinder water jacket, a cylinder head water jacket, an oil cooler, a thermostat, and a radiator. When the cooling system is operating, the flow direction of the cylinder water jacket in the cylinder water jacket is used to control the coolant, and the control of the cooling mode is achieved. [0003] In the related art, the cooling mode of the cooling system is typically controlled by 1 to 2 knocker. When the coolant temperature is low, the control cooling system performs a small cycle cooling mode so th...

Problems solved by technology

That is to say, in any cooling mode, the coolant will be completely sent to the radiator or oil cooler for cooling, which will cause the engine to heat up slowly when it is just started, and increase engine energy consumption

When two thermostats are used for control, the two thermostats control the coolant flowing out from the water jacket of the cylinder block and the water jacket of the cylinder head respectively, which can flexibly distribute the coolant flowing out of the water jacket of the cylinder body and the cylinder head, The effect of controlling the working temperature of the engine is good, but the cost of using two thermostats is relatively high
