Abstract

Disclosed herein is a cooling apparatus including a body on or below which a power module is mounted; a first cooling unit formed in the body in a longitudinal direction of the body to have first fluid passing therethrough and including an inlet to which the first fluid is introduced at one side of the longitudinal direction of the body and an outlet from which the first fluid is discharged at the other side thereof and a second cooling unit formed in the first cooling unit in a shape intersecting with first cooling unit to have second fluid passing therethrough.

Claims

1. A cooling apparatus, comprising:

a body on or below which a power module is mounted;

a first cooling unit formed in the body in a longitudinal direction of the body to have first fluid passing therethrough and including an inlet to which the first fluid is introduced at one side of the longitudinal direction of the body and an outlet from which the first fluid is discharged at the other side thereof; and

a second cooling unit formed in the first cooling unit in a shape intersecting with first cooling unit to have second fluid passing therethrough.

2. The cooling apparatus as set forth in claim 1, wherein the second cooling unit has a cylindrical shape.

3. The cooling apparatus as set forth in claim 2, wherein the second cooling unit has an oval cylindrical shape in such a way that a diameter measured in the longitudinal direction of the body is greater than a diameter measured in a height direction of the body.

4. The cooling apparatus as set forth in claim 1, wherein the second cooling unit has a polygonal shape.

5. The cooling apparatus as set forth in claim 4, wherein the second cooling unit is formed in such a way that a height thereof is reduced in the longitudinal direction of the body.

6. The cooling apparatus as set forth in claim 1, wherein the second cooling unit has a streamlined shape.

7. The cooling apparatus as set forth in claim 1, further comprising a third cooling unit formed in the first cooling unit and formed on at least one of an upper portion and a lower portion of the second cooling unit.

8. The cooling apparatus as set forth in claim 7, wherein the third cooling unit includes a plurality of columns that protrude from the second cooling unit.

9. The cooling apparatus as set forth in claim 1, wherein the second cooling units are in plural.

10. The cooling apparatus as set forth in claim 9, wherein the plurality of second cooling units are spaced apart from each other in the longitudinal direction of the body.

11. The cooling apparatus as set forth in claim 10, wherein the plurality of second cooling units are spaced apart from each other at equidistant intervals.

12. The cooling apparatus as set forth in claim 10, wherein an interval at which the plurality of second cooling units are spaced apart from each other is gradually reduced toward the other side of the longitudinal direction of the body from one side thereof.
