Abstract

Official abstract text for this publication.

A cooling system for the liquid immersion cooling of electronic components. The cooling system includes a container having a container wall and, in the interior, a reservoir for liquid heat transfer fluid in which positioning devices for electronic components are arranged. The container has a gas chamber for gaseous heat transfer fluid. In the gas chamber of the container, there is a heat exchanger device with heat exchanger tubes for liquefying gaseous heat transfer fluid, the heat exchanger tubes having outer fins on their outer sides. The heat exchanger tubes pass into the container wall or through the container wall at passage points. The heat exchanger tubes have an integral bond with the container wall at these passage points.

First claim

Opening claim text (preview).

The invention claimed is: 1 . A cooling system for the liquid immersion cooling of electronic components, comprising: a container having a container wall, an interior, a reservoir in the interior for liquid heat transfer fluid and a gas space for gaseous heat transfer fluid; positioning devices for electronic components arranged in the reservoir; and a heat exchanger device with a plurality of heat exchanger tubes in the gas space of the container for liquefying the gaseous heat transfer fluid, the heat exchanger tubes having respective outer sides with outer fins thereon, the heat exchanger tubes passing into the container wall or through the container wall at passage points, the heat exchanger tubes having an integral bond with the container wall at the passage points, at least a first one of the plurality of heat exchanger tubes comprising a first material and at least a second one of the plurality of heat exchanger tubes comprising a second material differing from the first material. 2 . The cooling system as claimed in claim 1 , wherein the outer fins at the passage points are directly adjacent to the container wall or come into contact with the container wall. 3 . The cooling system as claimed in claim 1 , wherein each integral bond is configured to be gas-tight and pressure-resistant. 4 . The cooling system as claimed in claim 1 , wherein the heat exchanger tubes, inside the passage points, have a tube internal diameter larger than a tube internal diameter of the heat exchanger tubes outside the passage points. 5 . The cooling system as claimed in claim 1 , wherein the heat exchanger tubes are soldered, adhesively bonded or welded into the container wall. 6 . The cooling system as claimed in claim 1 , wherein the outer sides of the heat exchanger tubes have spirally circulating outer fins. 7 . The cooling system as claimed in claim 1 , wherein the container is configured as a pressurized container, the pressurized container operating at negative pressure and/or positive pressure. 8 . The cooling system as claimed in claim 1 , wherein the first material comprises copper and the second material comprises steel. 9 . The cooling system as claimed in claim 1 , wherein the plurality of heat exchanger tubes in the gas space of the container all have the same thermodynamic function of liquefying the gaseous heat transfer fluid.
