Abstract

A cooling apparatus for a power-pack in a hybrid vehicle may include a power-pack that acquires traveling information of the vehicle and controls the operation of an engine and a motor, a low-temperature radiator that is connected with power-pack through a cooling water channel, dissipates heat from the cooling water discharged from power-pack, and is arranged in parallel with a radiator, and an electric water pump that is disposed in the cooling water channel and operated in response to an electric signal output from an ECU to circulate the cooling water through power-pack and low-temperature radiator. The cooling apparatus may also include a cooling fan. A cooling method of using the cooling apparatus may include determining engine operation, determining start of a water pump, and operating a water pump. The cooling method may also include starting a cooling fan, operating a cooling and examining a water pump.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2011-0068391 filed on Jul. 11, 2011, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The present invention relates to a cooling device in a hybrid vehicle, more specifically, to a cooling device and a cooling method for a power unit in a hybrid vehicle, which can specifically cool and control energy in a hybrid vehicle power unit. Background technique [0004] As fuel-efficient and environmentally friendly vehicles are rising as major issues in the vehicle industry, hybrid vehicles utilizing an engine and an electric motor as power supplies have come into focus. [0005] This hybrid vehicle is equipped with a power unit, which is a separate control device to control the driving of the engine and the motor, and the power unit collects the driving information of the vehicle and determines w...
