Abstract

The present invention relates to a heat exchanger for cooling an electrical element and a heat exchanger assembly for cooling an electrical element, and more particularly, to a heat exchanger for cooling an electrical element and a heat exchanger assembly for cooling an electrical element into which the electrical element may be easily inserted and in which both surfaces of the electrical element and a tube through which a coolant flows are formed to contact each other to improve cooling performance.

First claim

The invention claimed is:

1. An electrical element cooling module comprising:
a tube extended in a length direction, bent at a predetermined point so as to contact both surfaces, in a height direction, of the electrical element disposed in a partial region of an upper surface thereof, and having a heat exchange medium flowing therein;
a first header tank coupled and fixed to one end portion of the tube in the length direction;
a second header tank coupled and fixed to the other end portion of the tube in the length direction and disposed to be spaced apart from a center of the first header tank by a predetermined distance in the length direction in a state in which the tube is bent;
an inlet pipe formed in the first header tank and having the heat exchange medium introduced therethrough;
an outlet pipe formed in the second header tank and having the heat exchange medium discharged therethrough;
a lower plate disposed on a lower surface of the heat exchanger for cooling the electrical element;
an upper plate disposed on an upper surface of the heat exchanger for cooling the electrical element and coupled to the lower plate to apply a predetermined pressure to the heat exchanger for cooling the electrical element; and
an external housing in which the heat exchanger for cooling the electrical element, the lower plate, and the upper plate are accommodated.

2. The electrical element cooling module of claim 1 , further comprising an elastic member disposed in a space between the upper plate and the tube and having elasticity in the height direction.

3. The electrical element cooling module of claim 2 , wherein the elastic member is extended in the length direction so as to correspond to the tube, and is bent from both end portions in a zigzag form so that both sides thereof are symmetrical to each other on the basis of a central line in a width direction.

4. The electrical element cooling module of claim 1 , wherein the electrical element cooling module is in communication with the outside of the external housing through the inlet pipe and the outlet pipe, and
a first coupling hole and a second coupling hole into which the inlet pipe and the outlet pipe are inserted to protrude outwardly are formed in the external housing.

5. The electrical element cooling module of claim 4 , further comprising sealing members mounted between the inlet pipe and the first coupling hole and between the outlet pipe and the second coupling hole.

6. The electrical element cooling module of claim 4 , further comprising a fixing bracket connecting the heat exchanger for cooling the electrical element and the external housing to each other.

7. The electrical element cooling module of claim 6 , wherein the fixing bracket is coupled to one or more of the first header tank, the second header tank, the tube, the inlet pipe, and the outlet pipe.

8. The electrical element cooling module of claim 4 , further comprising on additional tube wherein in the case in which the number of tubes of the heat exchanger for cooling the electrical element is two and wherein the two tubes are neighboring,
wherein element fixing parts of the electrical element are disposed in an internal space formed by the neighboring two tubes spaced apart from each other in a width direction, and
wherein power supply parts of the electrical element are disposed in an external space.

9. The electrical element cooling module of claim 8 , wherein two upper plates are disposed at positions corresponding to the tubes, and
element coupling parts coupled to the element fixing parts are formed at sides of the upper plates neighboring to each other.

10. The electrical element cooling module of claim 9 , wherein the upper plates include second plate coupling parts formed at positions corresponding to first plate coupling parts formed at both sides of the lower plate in a width direction and coupled to the first plate coupling parts.
