Description

Electronic thermostat

Technical Field

The utility model relates to an electronic thermostat.

Background

The engine cooling system is used as an important control system in the engine control system, plays a key role in controlling the water temperature of the engine and starting the engine oil temperature, and the thermostat is used as a key part of the cooling system for controlling the large and small circulating waterways, so that the engine is ensured to operate at the most proper temperature. An electronic thermostat is a valve for controlling the flow path of a cooling fluid, and is a thermostat that generally includes a temperature sensing element for opening and closing the flow of air, gas or liquid by thermal expansion or contraction. During operation, the thermostat automatically adjusts the amount of cooling liquid entering the radiator according to the temperature of the cooling liquid, and changes the circulation range of the cooling liquid, so as to adjust the heat dissipation capacity of the engine cooling system and ensure that the engine works in a proper temperature range. The existing thermostat mainly used is a wax-type thermostat, the thermostat comprises an electric heating push rod, the state of paraffin in a thermostat shell is controlled based on the fact that whether the electric heating push rod is controlled to perform heating work or not, and the switching state of the thermostat is correspondingly controlled, so that the purpose of adjusting the heat dissipation capacity of an engine cooling system is achieved.

For example, in the chinese patent application EP6 engine with publication number CN205154361U (application number 201520979208.2), the plug and the heating core are both separately installed on the cover of the energy-saving device by adopting a structure separated from the housing, so that on one hand, the waterproof effect is poor, and on the other hand, water vapor easily contacts the lead wire in the assembly gap to cause short circuit of the heating core. On the other hand, the occupied space is large, and the harsh small space requirement cannot be met.
