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.
Claims21
A car motor cooling apparatus comprising:
- a motor housing in which a through-hole exposing a heating portion in a motor and a cooling path through which a cooling liquid flows along a stator via the through-hole are formed;
- a reservoir connected to the motor housing and having an inner space to be filled with the cooling liquid;
- and
- a nozzle plate installed in the inner space of the reservoir and including a nozzle configured to spray the cooling liquid directly onto the heating portion in the motor through the through-hole of the motor housing.
A car motor cooling apparatus comprising:
- a motor housing including a nozzle configured to spray a cooling liquid directly onto a heat generating portion of a motor;
- and
- a reservoir connected to the motor housing and having an inner portion filled with the cooling liquid.
