TEMPERATURE CONTROL VALVE OF COOLANT FOR FUEL CELL VEHICLE

摘要

PURPOSE: A coolant temperature control valve for a fuel cell is provided to control the temperature of coolant supplied to a fuel cell stack by rotating an operation plunger by a rotary method by directly connecting a driving motor and an operation plunger. CONSTITUTION: A coolant temperature control valve for a fuel cell comprises a valve housing(10), an operation plunger(30) and a driving motor(70). The valve housing comprises: a first inflow port(11) in which coolant supplied from a radiator is flowed in; a second inflow port(12) in which coolant supplied from a fuel cell stack is flowed in; and a discharge port(13) discharging coolant to the fuel cell stack; the operating plunger is connected to the discharge port to control the opening degree of the first and the second inflow ports. The driving motor rotates the operation plunger.
