Description

Technical Field

[0001] The invention relates to the technical field of thermostats, in particular to an electric heater assembly of an automobile thermostat. Background Art

[0002] Thermostat, also known as thermostat or thermostat, is a valve that controls the flow path of coolant. It is an automatic temperature control device that usually contains a temperature sensing component, which then expands or contracts to open or close the flow of air, gas or liquid.

[0003] The thermostat automatically adjusts the amount of water entering the radiator according to the coolant temperature, changes the circulation range of the coolant to adjust the coolant's heat dissipation capacity and ensure that the engine operates within the appropriate temperature range. The thermostat must be kept in good technical condition, otherwise it will seriously affect the normal operation of the engine. If the main valve of the thermostat is opened too late, it will cause the engine to overheat. If the main valve is opened too early, the engine preheating time will be extended and the engine temperature will be too low.

[0004] The thermostats that are widely used at present are wax type thermostats and electronic thermostats. The wax type thermostat melts the internal paraffin when the coolant temperature rises, so that the push pin pushes the valve, allowing the coolant to pass through the radiator to cool down the engine. The electronic thermostat heats the paraffin by controlling the ohmic resistance, controls the valve to allow the coolant to enter the heat dissipation pipe, and at the same time closes the internal circulation pipe through the auxiliary valve to close the internal circulation.

[0005] This type of electronic thermostat is usually equipped with a main valve for controlling the on and off of a large circulation and a sub-valve for controlling the on and off of a small circulation. In the small circulation state, the main valve is open and the sub-valve is closed. In the large circulation state, the main valve is closed and the sub-valve is opened. However, it only has the function of switching between the large circulation and the small circulation, and does not have the function of changing the flow rate. It cannot meet the design requirements of various cooling systems and needs to be improved. For this reason, we propose an electric heater assembly for an automotive thermostat.

[0041] Working principle: When the present invention is needed, the coolant enters the inner side of the connecting shell 5 through the inner side of the coolant inlet 6. When the cooling temperature is at a low temperature, the coolant circulates internally with the engine through the water pump from the inner side of the coolant internal circulation outlet 7. When the coolant temperature rises, it needs to pass through the radiator to cool the coolant. When it acts on the engine, the control component is connected through the control connection port 3 to connect the electric heating control component 24 on the inner side of the electric heating shell 1.
