Abstract

A cooling device of a computer rack equipped with a back panel including an evacuation zone, toward the exterior of the rack, of air having circulated over electric power components arranged within the computer rack, and a rear door in the thickness of which air cooling means is arranged. The cooling device also includes a supporting frame on which the rear door is mounted, molded to surround the air evacuation zone of the computer rack, and removable positioning means of the supporting frame against the back panel of the computer rack.

First claim

The invention claimed is:

1. A cooling device of a computer rack equipped with a back panel comprising an evacuation zone, toward an exterior of the computer rack, of air having circulated over electric power components arranged within the computer rack, comprising a rear door in the thickness of which air cooling means with at least one air/water heat exchanger is arranged, the cooling device comprising:
a supporting frame on which the rear door is mounted, the supporting frame being shaped to surround the air evacuation zone of the computer rack;
removable positioning means of the supporting frame disposed against the back panel of the computer rack;
first connection means to an external supply of cold water; and
second connection means to an external evacuation of hot water having circulated in the air/water heat exchanger;
wherein the first connection means comprises a flexible tube attached, at one extremity, to a connection device to the external supply and, at another extremity, to a pivoting connection device to the air/water heat exchanger,
wherein the second connection means comprises a flexible tube attached, at one extremity, to a connection device to the external evacuation and, at another extremity, to a pivoting connection device to the air/water heat exchanger, and
wherein the rear door is pivotally mounted on the supporting frame using a hinge whose vertical rotation axis is located on an exterior face of the supporting frame and the rear door and on the side of an opening of the rear door.

2. The cooling device according to claim 1 ,
wherein the supporting frame comprises autonomous means of floor support for said rear door, separate from floor support means of the computer rack, and which supports said rear door independently from said floor support means of the computer rack.

3. The cooling device according to claim 1 ,
wherein the connection devices to the external supply and to the external evacuation are arranged on the supporting frame and the pivoting connection devices to the air/water heat exchanger are arranged in the rear door.

4. The cooling device according to claim 1 , further comprising:
a plate for receiving and guiding flexible tubes of supply and evacuation including a plate with at least two overlaid horizontal supports fixed in a lower part of the supporting frame and constructed to be inserted under the computer rack at a location between the base of the computer rack and the floor on which the computer rack is supported using floor support means.

5. The cooling device according to claim 4 , wherein guiding means of the flexible tubes, said guiding means comprising guide pins, is arranged in the reception plate.

6. The cooling device according to claim 1 , wherein the air cooling means arranged in the thickness of the rear door further comprises:
a plurality of fans configured to draw air which has circulated over the electric power components toward the exterior of the computer rack.

7. A computer installation comprising:
a computer rack equipped with a back panel comprising an evacuation zone disposed toward an exterior of the computer rack, for air which has circulated over electric power components arranged within said computer rack; and
a cooling device comprising
a supporting frame on which a rear door is mounted, said supporting frame being shaped to surround the air evacuation zone of the computer rack;
removable positioning means of the supporting frame disposed against the back panel of the computer rack;
air cooling means arranged in a thickness of said rear door, said air cooling means including at least one air/water heat exchanger;
first connection means to an external supply of cold water; and
second connection means to an external evacuation of hot water having circulated in said at least one air/water heat exchanger;
wherein the first connection means comprises a flexible tube attached, at one extremity, to a connection device to the external supply and, at another extremity, to a pivoting connection device to the at least one air/water heat exchanger,
wherein the second connection means comprises a flexible tube attached, at one extremity, to a connection device to the external evacuation and, at another extremity, to a pivoting connection device to the at least one air/water heat exchanger, and
wherein the rear door is pivotally mounted on the supporting frame using a hinge whose vertical rotation axis is located on an exterior face of the supporting frame and the rear door and on the side of an opening of the rear door.
