Abstract

Official abstract text for this publication.

A cooling unit of a drive motor includes: a fixing member installed on an inner wall surface of a motor housing and configured to fix a stator core of the drive motor, wherein the fixing member has a ring shape, includes a flow path formed therein in order to allow a cooling medium to flow, and includes a cooling medium inlet and a cooling medium outlet formed to be connected to the flow path, the flow path includes a first path connecting the cooling medium inlet and the cooling medium outlet to each other at one side and a second path connecting the cooling medium inlet and the cooling medium outlet to each other at another side, and the first and second paths have different flow cross sections and are connected to each other.

First claim

Opening claim text (preview).

What is claimed is: 1. A cooling unit of a drive motor, comprising: a motor housing being formed in a ring shape and configured to fix a stator core of the drive motor, wherein the motor housing includes a flow path formed therein in order to allow a cooling medium to flow, and includes a cooling medium inlet and a cooling medium outlet formed to be connected to the flow path, and the flow path includes a first path connecting the cooling medium inlet and the cooling medium outlet to each other at one side, and a second path connecting the cooling medium inlet and the cooling medium outlet to each other at another side, and the first and second paths have different flow cross sections and are connected to each other. 2. The cooling unit of a drive motor of claim 1 , wherein the motor housing includes a fixing member being formed in a ring shape and being installed on an inner wall surface thereof so as to fix the stator core of the drive motor, and the flow path, the cooling medium inlet, and the cooling medium outlet are formed at the fixing member. 3. The cooling unit of a drive motor of claim 1 , wherein: the first and second paths have different lengths, and the first path has a length longer than that of the second path. 4. The cooling unit of a drive motor of claim 3 , wherein: the first path has a flow cross section larger than that of the second path. 5. The cooling unit of a drive motor of claim 4 , wherein: the first and second paths allow the same flow rate of cooling medium to flow.
