Abstract

An electronic component case for a vehicle is provided. The electronic component case includes a case body having a first space in which electronic components are disposed and a second space, which has an opening that is opened to the outside, defined adjacent to the first space to receive heat generated from the electronic components, wherein a coolant for cooling the electronic components is introduced into and discharged from the second space, and a cover disposed on the case body to seal the opening of the second space. The cover includes a first cover sealing the opening and a second cover sealing the opening and having one surface on which a first cooling part for increasing a surface area of the second cover is disposed. The first cover and the second cover are compatible with each other.

Claims

1. An electronic component case for a vehicle, the electronic component case comprising:

a case body having a first space in which electronic components are disposed and a second space that is defined adjacent to the first space to receive heat generated from the electronic components and into which coolant for cooling the electronic components is introduced and discharged; and

a cover disposed on the case body to seal the second space,

wherein the cover comprises a first cover and a second cover sealing the second space, the second cover having one surface on which a first cooling part for increasing a surface area of the second cover is disposed,

wherein the first cover and the second cover are compatible with each other,

wherein the first and second spaces are partitioned by an inner plate on which the electronic components are disposed,

wherein a surface of the second cover that faces the second space is in contact with the inner plate when the second cover is disposed on the case body.

2. The electronic component case according to claim 1, wherein:

the first cover is disposed on the case body when the coolant is introduced into and discharged from the second space; and

the second cover is disposed on the case body when the coolant is not introduced into and discharged from the second space.

3. The electronic component case according to claim 2, wherein the cover is formed of aluminum or iron.

4. The electronic component case according to claim 1, wherein the first cooling part comprises a plurality of pins.

5. The electronic component case according to claim 2, wherein the first cooling part comprises a plurality of plates.

6. The electronic component case according to claim 1, wherein the case body further has a coolant inflow hole through which the coolant is introduced into the second space and a coolant discharge hole through which the coolant is discharged from the second space.

7. The electronic component case according to claim 6, further comprising a stopper inserted into each of the coolant inflow hole and the coolant discharge hole to seal the second space externally when the second cover is disposed on the case body.

8. The electronic component case according to claim 7, wherein the second space is filled with the coolant.

9. The electronic component case according to claim 1, further comprising a first sealer provided on an edge of the cover and compressed by the case body when the cover is disposed on the case body.

10. The electronic component case according to claim 1, wherein a second cooling part is disposed on a surface of the inner plate that faces the second space.

11. The electronic component case according to claim 10, wherein the second cooling part comprises a plurality of pins.

12. The electronic component case according to claim 1, wherein thermal grease is applied to a portion of the second cover of which a surface is in contact with the inner plate.
