Abstract

A rack for an aeronautical platform comprising two parallel shelves positioned between a front face and a rear face of the platform, the rack being inserted into the platform by translation from the front face to the rear face the rack containing electronic equipment extending primarily in a plane, the electronic equipment being positioned in a useful compartment of the rack and cooled by forced convection. The electronic equipment is positioned in such a way that its main plane is parallel to the shelves. The rack comprises means for guiding an air flow used for the cooling of the electronic equipment item, the air flow penetrating into the useful compartment parallel to the plane of the electronic equipment item and at right angles to the direction of insertion of the rack into the platform.

First claim

The invention claimed is:

1. Rack intended to equip a platform comprising two parallel shelves positioned between a front face and a rear face of the platform, the rack being intended to be inserted into the platform by translation from the front face to the rear face, the rack containing at least one electronic equipment item extending primarily in a plane, the electronic equipment item being positioned in a useful compartment of the rack, the electronic equipment item being cooled by forced convection, the electronic equipment item being positioned in the useful compartment such that its main plane is parallel to the shelves, in that the electronic equipment item can be plugged into the rack in the same direction as the direction of insertion of the rack into the platform and in that the rack comprises means for guiding an air flow used for the cooling of the electronic equipment item, the air flow penetrating into the useful compartment parallel to the plane of the electronic equipment item and at right angles to the direction of insertion of the rack into the platform.

2. Rack according to claim 1 , wherein the guiding means comprise an inlet box covering a first lateral face of the useful compartment, and wherein the inlet box ensures the guiding of the air flow towards the useful compartment.

3. Rack according to claim 2 , wherein the guiding means comprise piercings produced in the first lateral face of the useful compartment so as to allow the passage of the air flow from the inlet box to the useful compartment, the piercings being defined according to a desired distribution of the air flow in the useful compartment.

4. Rack according claim 3 , wherein the guiding means comprise at least one fan making it possible to drive the air flow used for the cooling of the electronic equipment item.

5. Rack according to claim 3 , wherein the guiding means comprise an outlet box covering a second lateral face of the useful compartment, and in that the outlet box ensures the guiding of the air flow leaving the useful compartment.

6. Rack according to claim 3 , wherein one of the shelves, called bottom shelf, can deliver the air flow used for the cooling of the electronic equipment item, and in that the guiding means are configured to allow the guiding of the air flow originating from the bottom shelf to the useful compartment of the rack.

7. Rack according to claim 6 , wherein the guiding means comprise a console bearing the useful compartment, and in that the console ensures the guiding of an air flow originating from the bottom shelf to the useful compartment.

8. Rack according claim 2 , wherein the guiding means comprise at least one fan making it possible to drive the air flow used for the cooling of the electronic equipment item.

9. Rack according to claim 2 , wherein the guiding means comprise an outlet box covering a second lateral face of the useful compartment, and in that the outlet box ensures the guiding of the air flow leaving the useful compartment.

10. Rack according to claim 2 , wherein one of the shelves, called bottom shelf, can deliver the air flow used for the cooling of the electronic equipment item, and in that the guiding means are configured to allow the guiding of the air flow originating from the bottom shelf to the useful compartment of the rack.

11. Rack according to claim 10 , wherein the guiding means comprise a console bearing the useful compartment, and in that the console ensures the guiding of an air flow originating from the bottom shelf to the useful compartment.

12. Rack according to claim 1 , wherein an overall length of the electronic equipment item measured at right angles to the direction of insertion is greater than an overall height of the rack measured at right angles to the two shelves.

13. Rack according to claim 1 , wherein characterized in that the electronic equipment item comprises a backplane connector positioned in such a way that its direction of insertion is the direction of insertion of the rack into the platform.

14. Rack according claim 1 , wherein the guiding means comprise at least one fan making it possible to drive the air flow used for the cooling of the electronic equipment item.

15. Rack according to claim 14 , wherein one of the shelves, called bottom shelf, can deliver the air flow used for the cooling of the electronic equipment item, and in that the guiding means are configured to allow the guiding of the air flow originating from the bottom shelf to the useful compartment of the rack.

16. Rack according to claim 15 , wherein the guiding means comprise a console bearing the useful compartment, and in that the console ensures the guiding of an air flow originating from the bottom shelf to the useful compartment.

17. Rack according to claim 14 , wherein the guiding means comprise an outlet box covering a second lateral face of the useful compartment, and in that the outlet box ensures the guiding of the air flow leaving the useful compartment.

18. Rack according to claim 17 , wherein one of the shelves, called bottom shelf, can deliver the air flow used for the cooling of the electronic equipment item, and in that the guiding means are configured to allow the guiding of the air flow originating from the bottom shelf to the useful compartment of the rack.

19. Rack according to claim 1 , wherein one of the shelves, called bottom shelf, can deliver the air flow used for the cooling of the electronic equipment item, and in that the guiding means are configured to allow the guiding of the air flow originating from the bottom shelf to the useful compartment of the rack.

20. Rack according to claim 19 , wherein the guiding means comprise a console bearing the useful compartment, and in that the console ensures the guiding of an air flow originating from the bottom shelf to the useful compartment.
