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 comprising:

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,

wherein the cover comprises 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,

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

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 discharge 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 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 from the outside 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 the first and second spaces are partitioned by an inner plate on which the electronic components are seated.

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

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

13. The electronic component case according to claim 10, wherein, when the second cover is disposed on the case body, a surface of the second cover that faces the second space is in contact with the inner plate.

14. The electronic component case according to claim 13, wherein thermal grease is applied to a portion of the second cover of which the surface is in contact with the inner plate.

15. An electronic component case for a vehicle in which electronic components are disposed, the electronic component case comprising:

a case body having a first space in which electronic components are disposed and a second space receiving heat generated from the electronic components and having an opening that is opened to the outside, wherein a coolant inflow hole through which a coolant is introduced into the second space and a coolant discharge hole through which the coolant is discharged from the second space are defined in one surface of the case body; and

a cover disposed on the case body to seal the opening,

wherein the cover comprises a first cover and a 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 and second covers are compatible with each other

16. The electronic component case according to claim 15, wherein the first cooling part comprises a plurality of pins and a plurality of plates disposed outside the plurality of pins.

17. The electronic component case according to claim 15, further comprising a stopper inserted into each of the coolant inflow hole and the coolant discharge hole to prevent the coolant from being introduced into and discharged from the second space when the second cover is disposed on the case body.

18. The electronic component case according to claim 17, wherein the second space is filled with the coolant.
