Abstract
An electronic thermostat, into which cooling water is flowed from a cylinder head of an engine through a first inlet, controls the flow rate of the received cooling water supplied to outside ambient air exposure. The electronic thermostat includes a first valve for controlling the flow rate of the cooling water supplied to a first passage for connecting a first outlet of the electronic thermostat and a water pump and includes a second valve for controlling the flow rate of the cooling water flowing through a second passage for connecting the outlet of a radiator and a cylinder block of the engine.
Claims20
A cooling system of an engine, the cooling system comprising:
- the engine;
- a water pump for supplying cooling water to the engine;
- an electronic thermostat into which the cooling water is flowed from a cylinder head of the engine through a first inlet, the electronic thermostat controlling the flow rate of the received cooling water supplied to the outside;
- and
- a control unit for controlling the electronic thermostat,
- wherein the electronic thermostat comprises
- a first valve for controlling the flow rate of the cooling water supplied to a first passage for connecting a first outlet of the electronic thermostat and a water pump, and
- a second valve for controlling the flow rate of the cooling water flowing through a second passage for connecting an outlet side of a radiator and an inlet side of a cylinder block of the engine from the outlet side of the radiator to the inlet side of the cylinder block,
- wherein the control unit controls the first valve, the second valve, and a third valve by controlling a drive heater of the electronic thermostat, and
- wherein the second valve integrally moves together according to a movement of the first valve.
A cooling system of an engine, the cooling system comprising:
- the engine;
- a water pump for supplying cooling water to the engine;
- an electronic thermostat into which the cooling water is flowed from a cylinder head of the engine through a first inlet, the electronic thermostat controlling the flow rate of the received cooling water supplied to the outside;
- and
- a control unit for controlling the electronic thermostat,
- wherein the electronic thermostat includes
- a first valve for controlling the flow rate of the cooling water supplied to a first passage for connecting a first outlet of the electronic thermostat and a water pump, and
- a second valve for controlling the flow rate of the cooling water flowing through a second passage for connecting an outlet side of a radiator and an inlet side of a cylinder block of the engine from the outlet side of the radiator to the inlet side of the cylinder block,
- wherein the control unit controls the first valve, the second valve, and a third valve by controlling a drive heater of the electronic thermostat, and
- wherein the first passage is branched at a first branch point from a third passage connected from the outlet side of the radiator to the water pump to be connected to an inlet side of the thermostat.
A cooling system of an engine, the cooling system comprising:
- the engine;
- a water pump for supplying cooling water to the engine;
- an electronic thermostat into which the cooling water is flowed from a cylinder head of the engine through a first inlet, the electronic thermostat controlling the flow rate of the received cooling water supplied to the outside;
- and
- a control unit for controlling the electronic thermostat,
- wherein the electronic thermostat includes
- a first valve for controlling the flow rate of the cooling water supplied to a first passage for connecting a first outlet of the electronic thermostat and a water pump, and
- a second valve for controlling the flow rate of the cooling water flowing through a second passage for connecting an outlet side of a radiator and an inlet side of a cylinder block of the engine from the outlet side of the radiator to the inlet side of the cylinder block,
- wherein the control unit controls the first valve, the second valve, and a third valve by controlling a drive heater of the electronic thermostat, and
- wherein the third valve is configured to control the flow rate of the cooling water supplied to a fourth passage for connecting a second outlet of the electronic thermostat and an inlet side of the radiator.
