ELECTRONIC THERMOSTAT

摘要

PURPOSE: An electric thermostat is provided to minimize time used for increasing temperature to a target temperature using a glow plug type heater. CONSTITUTION: An electric thermostat comprises a housing (100), a wax case (200), a glow plug type heater (300), a driver (400), a main valve (500), and an elastic member (600). The housing is connected to multiple flow paths (P1, P2) where cooling water of an engine flows. The wax case is installed inside the housing and has a wax accommodating space. The glow plug type heater is inserted into wax which fills the wax accommodating space, and generates heat through input from an external power. The driver moves depending on the deformation of the wax due to the heat of the heater. The main valve opens and closes a radiator side flow path (P1) by the movement of the driver. The elastic member elastically supports the main valve to the radiator side flow path.
