COOLING SYSTEM OF VEHICLE HAVING MOTOR

摘要

A cooling system of vehicle having a motor includes: a mainline that provides a coolant flow channel; a radiator that is installed at one side of the mainline; a pump that is installed at the other side of the mainline; a first branch line and a second branch line that are branched from the main line; a first heat emitter and second heat emitter that are installed at the first branch line and the second branch line, respectively; and a control valve that supplies a coolant necessary for the first heat emitter and the second heat emitter by controlling flow of a coolant flowing from the mainline to the first branch line or the second branch line.;Therefore, by controlling a quantity of each coolant that is supplied to a first heat emitter including an inverter and a motor and a second heat emitter including a DC converter, a capacity of a coolant pump or an operation load can be reduced and thus entire cooling efficiency can be improved.

1. A cooling system of vehicle having a motor, the cooling system comprising:
a mainline configured to provide a coolant flow channel; a radiator installed at a first side of the mainline; a pump installed at a second side of the mainline; a first branch line and a second branch line that branch from the main line; a first heat emitter installed at the first branch line, and a second heat emitting installed at the second branch line; and a control valve configured to supply a coolant necessary for the first heat emitter and the second heat emitter by controlling flow of a coolant flowing from the mainline to at least one of the first branch line or the second branch line.
