AUXILIARY COOLING SYSTEM

摘要

An auxiliary cooling system which is provided separately from an engine cooling passage in a vehicle provided with a turbo engine. The auxiliary cooling system includes a first line which connects a radiator and an intercooler to each other and on which an electric water pump is installed. A second line connects the intercooler and an intake manifold. A third line connects the intake manifold and the radiator, and a bypass valve selectively directly transfers cooling water, heated while passing through a turbine housing provided on a path of the third line, to the radiator or transfers the cooling water to the radiator via an engine block or a heater. Cooling water discharged from the intake manifold passes through an ETC (electronic throttle control) unit and thus reduces a temperature of intake air passing through the ETC unit.

1. An auxiliary cooling system installed separately from an engine cooling passage in a vehicle provided with a turbo engine, the auxiliary cooling system comprising:
a first line connecting a radiator and an intercooler to each other, with an electric water pump installed on the first line so that cooling water flows from the radiator toward the intercooler through the first line; a second line connecting the intercooler and an intake manifold to each other and allowing the cooling water to flow therethrough; a third line connecting the intake manifold and the radiator to each other and allowing the cooling water to flow therethrough; and a bypass valve that selectively directs transferring cooling water, heated while passing through a turbine housing provided on a path of the third line, to the radiator or transferring the cooling water to the radiator via an engine block or a heater, wherein cooling water discharged from the intake manifold passes through an ETC (electronic throttle control) unit and thus reduces a temperature of intake air passing through the ETC unit.
