COOLING CASE PROVIDING COOLING OF ELECTRONIC CARDS

Abstract

A cooling case provides cooling of electronic cards. The cooling case provides efficient cooling of electronic cards found in military electronics packaging, and includes a cold plate having a fin structure.

Claims

1. A cooling case, comprising: a cold plate located on electronic cards in military electronics packaging, wherein the cooling case cools the electronic cards, a cold plate opening formed on the cooling case, wherein the cold plate opening provides an installment of the cold plate to a side part of the cooling case, fins, wherein the fins provide transmission of heat of the electronic cards located on the cold plate to a fluid passing through the cooling case, wherein the fins are at a location where the cold plate is connected to the cooling case, and an outer cover closed onto the cold plate opening, wherein the outer cover cuts a connection of the cold plate with an outer environment.

2. The cooling case according to claim 1, wherein the cold plate comprises a fin wall, wherein the fin wall fits the fins at a location where the cooling case is connected to cold plate.

3. The cooling case according to claim 1, further comprising an area where the fins are connected to the cooling case, wherein the area has air or a fluid formed on the cooling case passing through.

4. The cooling case according to claim 1, further comprising a secondary sealing member located between the cooling case and the cold plate, wherein the secondary sealing member provides sealing.

5. The cooling case according to claim 1, further comprising a primary sealing member, wherein the primary sealing member is located between the cooling case and the outer cover, wherein the primary sealing member provides sealing.

6. The cooling case according to claim 2, further comprising an area where the fins are connected to the cooling case, wherein the area has air or a fluid formed on the cooling case passing through.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] In this detailed description, the preferred embodiments of the cooling case (1) being subject of this invention have been disclosed solely for the purpose of better understanding of the subject and described in a manner not causing any restrictive effect.

[0028] The invention is a cooling case (1) providing cooling case including a cold plate (3) of electronic cards in military electronics packaging and located on electronic cards and comprises [0029] cold plate opening (2) provided on cooling case (1) to provide installment of cold plate (3) to cooling case (1) side part, [0030] fins (7) providing transmission of heat of electronic cards located onto cold plate (3) to fluid passing through cooling case (1), located in parts where cold plate (3) is connected to cooling case (1), [0031] outer cover (4) closed onto cold plate opening (2) to cut connection of cold plate (3) with outer environment.

[0032] Cooling case (1) of the invention includes in the most general form, a cold plate (3) where electronic card is located. Cold plate (3) is mounted to cooling case (1) by passing it through cold plate opening (2) located on one side of cooling case (1). Connection of cold plate (3) to cooling case (1) is provided by primary connection members (8) which are preferably screw. An outer cover (4) is connected onto cold plate opening (2) to cut connection of cold plate (3) mounted into cooling case (1) with outer environment. Also connection of outer cover (4) to cooling case (1) is provided by secondary connection members (9) which are preferably screw.

[0033] Fins (7) are provided on side parts where cold plate (3) is connected to cooling case (1). Similarly, inner walls where cooling case (1) is connected to cold plate (3) are of finned form. Said fins (7) provide transmission of heat taken by cold plate (3) to fluid passing through cooling case (1). The areas where fins (7) are connected on cooling case (1) have areas containing air or fluid passing formed on cooling case (1). Thus fins (7) are enabled to take heat directly (without use of any connection part) from cold plate (3).

[0034] Secondary sealing members (6) are provided between cold plate (3) and cooling case (1) in order to provide sealing between cold plate (3) and cooling case (1). Also, primary sealing member (5) is provided between outer cover (4) and cooling case (1). Said primary sealing member (5) and secondary sealing members (6) are preferably gasket. Thus, a sealing structure is achieved in cases (1) run by both air cooling and fluid cooling and thermal loss is prevented.

[0035] With embodiment of invention cold plate (3) is on fins (7) and thus contact with direct fluid (air or fluid) is provided and a performance loss of 10 - 15° C. that might occur in a card having 100 W-120W heat load to occur in the related art is eliminated. Also, if it is desired to use said card at higher performance, fin (7) design of cold plate (3) is changed and thermal performance can be improved without need to change cooling case (1).
