Abstract
The present invention is proposed to simplify a structural complexity of a conventional oil cooling method for a car motor, reduce a material cost, and also achieve improved cooling performance, in which a cooling liquid, which is provided through a cooling pipe in a conventional case, is sprayed onto a heating portion in a motor through a reservoir tank and a nozzle which are attached to a motor housing through a direct cooling method. A reservoir space is integrally formed with the motor housing or is formed to be separate from the motor housing, a pressure of the cooling liquid is uniformly maintained and damped, and the cooling liquid introduced into the reservoir tank through a flow path formed without a cooling pipe is directly sprayed onto the heating portion to cool the heating portion such as a stator core or a coil.
