Abstract
A coolant flow control apparatus may include a coolant controller housing of which an inlet for coolant to flow in, an outlet for the coolant to flow out, a first coolant supply line and a second coolant supply line are formed, a water pump mounted to the coolant controller housing for transmitting the coolant, a valve plate selectively opening/closing the first coolant supply line, a valve piston selectively opening/closing the second coolant supply line, a driving unit selectively moving the valve plate and the valve piston for closing or opening the first coolant supply line and the second coolant supply line respectively and a controller configured for controlling an operation of the driving unit.
Claims17
A coolant flow control apparatus comprising:
- a coolant controller housing including:
- an inlet for coolant to flow in;
- an outlet for the coolant to flow out;
- a first coolant supply line;
- and
- a second coolant supply line;
- a water pump mounted to the coolant controller housing for transmitting the coolant;
- a valve plate configured for selectively opening the first coolant supply line;
- a valve piston configured for selectively opening the second coolant supply line;
- a driving unit selectively moving the valve plate and the valve piston for closing or opening the first coolant supply line and the second coolant supply line respectively;
- and
- a controller connected to the driving unit and configured for controlling an operation of the driving unit.
A cooling system comprising:
- an engine including an upper cylinder head, an upper line connected to the upper cylinder head and transmitting coolant to the upper cylinder head, a lower cylinder head connected to the upper cylinder head, a lower line connected to the lower cylinder head and transmitting coolant to the lower cylinder head, an engine block connected to the lower cylinder head and a block line connected to the engine block and transmitting coolant to the engine block;
- a plurality of heat exchange elements receiving coolant from the lower cylinder head;
- a radiator connected to the upper cylinder head and the engine block and receiving coolant from the upper cylinder head and the engine block;
- a coolant controller housing of which an inlet receiving coolant from the plurality of heat exchange elements and the radiator, an outlet fluidically-communicating with the lower line, a first coolant supply line fluidically-communicating with the upper line and a second coolant supply line fluidically-communicating with the block line are formed;
- a water pump mounted to the coolant controller housing for transmitting the coolant;
- a valve plate configured for selectively opening the first coolant supply line;
- a valve piston configured for selectively opening the second coolant supply line;
- a driving unit selectively moving the valve plate and the valve piston for closing or opening the first coolant supply line and the second coolant supply line respectively;
- a vehicle operation state detecting portion including a first coolant temperature sensor detecting a temperature of coolant in the lower cylinder head and outputting a first signal and a second coolant temperature sensor detecting a temperature of coolant in the engine block and outputting a second signal;
- and
- a controller connected to the driving unit and the vehicle operation state detecting portion and configured for controlling an operation of the driving unit according to at least one of the first and second signals of the vehicle operation state detecting portion.
