Abstract

An arrangement for a computer system includes a heat-producing expansion card and a cooling device. The cooling device has at least one fan and a hollow body with a first opening and a second opening to cool the expansion card. The hollow body is arranged with the first opening on the expansion card. The at least one fan is arranged on the hollow body in a region of the second opening or is at least partly surrounded by the hollow body by the second opening. The at least one fan produces a flow of air through the hollow body to cool the expansion card.

First claim

What is claimed is:

1 . An arrangement for a computer system, having
a heat-producing expansion card; a cooling device with at least one fan and a hollow body with a first opening and a second opening for cooling the expansion card; wherein the first opening is opposite the second opening; the hollow body is arranged with the first opening on the expansion card, and the expansion card is inserted into the first opening of the hollow body; the at least one fan is arranged on the hollow body in the region of the second opening or is at least partly surrounded by the hollow body by means of the second opening; the at least one fan is designed to produce a flow of air through the hollow body for cooling the expansion card.

2 . The arrangement according to claim 1 , wherein the hollow body is cuboidal.

3 . The arrangement according to claim 1 , wherein the hollow body at least partly surrounds the expansion card with the first opening from four sides.

4 . The arrangement according to claim 3 , wherein the hollow body has at least one third opening in the region of the expansion card surrounded by the hollow body in order to expose a connector of the expansion card.

5 . The arrangement according to claim 1 , wherein the hollow body consists substantially of a plastic material.

6 . The arrangement according to claim 1 , wherein the expansion card has a temperature sensor that controls the at least one fan.

7 . The arrangement according to claim 1 , wherein the at least one fan has a temperature sensor that controls the at least one fan.

8 . The arrangement according to claim 1 , which has a temperature sensor arranged in the region of the expansion card to control the at least one fan.

9 . The arrangement according to claim 1 , wherein a card holding element is arranged on an outer side of the hollow body for being held in a receiving opening of a card holder within a housing of the computer.

10 . The arrangement according to claim 1 , wherein the expansion card is a computing card, in particular a high-end computing card.

11 . The arrangement according to claim 10 , wherein the computing card comprises a cared and a card housing in which the card is encapsulated.

12 . The arrangement according to claim 11 , wherein a flow of air enters the card housing of the computing card and exits through the computing card via a slot bracket of the computing card.

13 . The arrangement according to claim 1 , wherein the hollow body is fixed mechanically onto the expansion card.

14 . A computer system, in particular a desktop or tower system, having:
a housing; a slot panel on a first housing side of the housing; a card holder with a receiving opening, the card holder being arranged within the housing opposite to the first housing side; and a mainboard arranged in the housing, said mainboard having at least one plug connection; and an arrangement according to claim 1 with an expansion card and a cooling device; wherein: the expansion card and the cooling device are arranged within the housing; the expansion card is connected to the mainboard by means of the at least one plug connection; the expansion card is mounted at the slot panel via a slot bracket; at least one holding element is mounted on an outer side of the hollow body; the hollow body is arranged with the first opening on the expansion card, and the expansion card is inserted into the first opening of the hollow body; and the at least one holding element of the hollow body is held in the receiving opening of the card holder.

15 . The computer system according to claim 14 , wherein the mainboard has at least one temperature sensor that controls the at least one fan.
