Product Description
Automobile thermostat is a device for controlling the temperature of engine cooling system, and its structure usually includes the following parts:
1. Housing: The housing is the outer shell of the thermostat, usually made of metal material, which is used to protect the internal components and connect to the engine cooling system.
2. Valve Core: The valve core is the core component of the thermostat, and usually consists of a wax-like substance or a piston controlled by a spring. Its function is to control the flow of coolant according to its temperature change.
3. Spring: The spring is an elastic element used to control the movement of the valve core. According to the temperature of the coolant, the spring will contract or extend, thus controlling the opening or closing of the valve core.
4. Temperature Sensing Element: A temperature sensing element is a sensor used to detect the temperature of coolant. It is usually located inside the thermostat and connected to the valve core or spring.
According to different working principles and application methods, automobile thermostats can be divided into the following types:
1. Mechanical Thermostat: Mechanical thermostat is the most common type, which controls the flow of coolant through the mechanical movement of valve core and spring. When the coolant temperature rises, the valve core opens, allowing the coolant to flow to the radiator. When the temperature drops, the valve core closes to prevent the coolant from flowing.
2. Electronic Thermostat: Electronic thermostat uses electronic components to control the flow of coolant. It detects the temperature of coolant through a temperature sensor and controls the opening and closing of the valve core through an electronic control unit.
3. Variable Thermostat: The variable thermostat can adjust the coolant temperature according to the engine load and working conditions. It usually uses electronic control unit and variable damping mechanism to realize temperature adjustment.
It should be noted that different models and engine types may use different types of thermostats. The specific thermostat structure and type may be different. Therefore, when repairing and replacing the thermostat, it is best to refer to the owner's manual of the vehicle or consult a professional automobile maintenance technician.
