Abstract

Provided is an electric element cooling module, and more particularly, an electric element cooling module in which opposite surfaces of an electric element surface-contacts a cooling flow passage portion in which a cooling fluid flows and, thus, an electric element is easily inserted and an interval between cooling flow passages arranged in two lines in a width direction is controlled through terminals installed inside an electric element in a width direction, thereby preventing signal interference between terminals and achieving excellent assembly.

First claim

What is claimed is:

1. An electric element cooling module comprising:
a cooling flow passage portion formed to allow a cooling fluid to flow therein;
a header tank including a first header tank coupled to one end of the cooling flow passage portion and a second header tank coupled to the other end of the cooling flow passage portion and disposed above the first header tank; and
a heat exchanger for cooling an electric element including an entrance pipe including an inlet pipe formed in the header tank to introduce the cooling fluid and an outlet pipe configured to discharge the cooling fluid,
wherein the cooling flow passage portions are bent at predetermined points and adhered to opposite surfaces of an electric element disposed between surfaces of the cooling flow passage portions, which face each other, and are arranged in two lines to be spaced apart from each other in a width direction,
wherein the cooling flow passage portions are formed in such a way that an interval between the cooling flow passage portions in a width direction is greater than the sum of lengths of terminals installed inside the electric element in a width direction,
wherein the electric element cooling module further comprises a lower housing disposed on a lower surface of the heat exchanger for cooling the electric element, and
a first fix bracket fixedly coupled to any one selected from the first header tank or the second header tank and the lower housing, and
wherein an interval in the width direction between the terminals in one of the two lines and in the other two lines is less than a diameter of the inlet pipe.

2. The electric element cooling module of claim 1 , further comprising a heating component positioned on an upper surface of the cooling flow passage portion.

3. The electric element cooling module of claim 1 , wherein the terminals disposed in one of the two lines are different in height from those in the other one of the two lines, and
wherein the terminals in the two lines are aligned such that any one selected from opposite surfaces thereof in a height direction is positioned on the same plane.

4. An electric element cooling module comprising:
a cooling flow passage portion formed to allow a cooling fluid to flow therein;
a header tank including a first header tank coupled to one end of the cooling flow passage portion and a second header tank coupled to the other end of the cooling flow passage portion and disposed above the first header tank; and
a heat exchanger for cooling an electric element including an entrance pipe including an inlet pipe formed in the header tank to introduce the cooling fluid and an outlet pipe configured to discharge the cooling fluid,
wherein the cooling flow passage portions are bent at predetermined points and adhered to opposite surfaces of an electric element disposed between surfaces of the cooling flow passage portions, which face each other, and are arranged in two lines to be spaced apart from each other in a width direction,
wherein the cooling flow passage portions are formed in such a way that an interval between the cooling flow passage portions in a width direction is greater than the sum of lengths of terminals installed inside the electric element in a width direction,
wherein the electric element cooling module further comprises a lower housing disposed on a lower surface of the heat exchanger for cooling the electric element, and
wherein the cooling flow passage portion further includes a fix portion for coupling with the lower housing, and at least one fix portion protrudes from a lateral surface in a width direction of the cooling flow passage portion and includes a through hole penetrating in a height direction.

5. The electric element cooling module of claim 4 , wherein the terminals disposed in one of the two lines are different in height from those in the other one of the two lines, and
wherein the terminals in the two lines are aligned such that any one selected from opposite surfaces thereof in a height direction is positioned on the same plane.

6. The electric element cooling module of claim 4 , wherein an interval in the width direction between the terminals in one of the two lines and in the other one of the two lines is less than a diameter of the inlet pipe.

7. An electric element cooling module comprising:
a cooling flow passage portion formed to allow a cooling fluid to flow therein;
a header tank including a first header tank coupled to one end of the cooling flow passage portion and a second header tank coupled to the other end of the cooling flow passage portion and disposed above the first header tank; and
a heat exchanger for cooling an electric element including an entrance pipe including an inlet pipe formed in the header tank to introduce the cooling fluid and an outlet pipe configured to discharge the cooling fluid,
wherein the cooling flow passage portions are bent at predetermined points and adhered to opposite surfaces of an electric element disposed between surfaces of the cooling flow passage portions, which face each other, and are arranged in two lines to be spaced apart from each other in a width direction, wherein the heat exchanger for cooling the electric element includes a plurality of electric elements with different heat values; and
wherein the header tank and the cooling flow passage portion form two cooling flow passages in which a cooling fluid passes and a cooling flow passage with a relatively small length exchanges heat with an electric element with a high heat value.

8. The electric element cooling module of claim 7 , wherein the cooling flow passage includes a header tank flow passage formed on the header tank and tube flow passages formed on the respective cooling flow passage portions; and wherein the tube flow passages have the same length.

9. The electric element cooling module of claim 8 , wherein the header tank flow passage includes a plurality of distribution flow passages for distributing a cooling fluid introduced at the inlet pipe to each of the cooling flow passage portions and a plurality of integrated flow passages for moving a cooling fluid passing through each of the cooling flow passage portions to the outlet pipe; and
wherein the plurality of distribution flow passages and the plurality of integrated flow passages that are connected to different cooling flow passages have different lengths.

10. An electric element cooling module comprising:
a cooling flow passage portion formed to allow a cooling fluid to flow therein;
a header tank including a first header tank coupled to one end of the cooling flow passage portion and a second header tank coupled to the other end of the cooling flow passage portion and disposed above the first header tank; and
