Nvidia patents liquid-cooling plate with dual flow paths for chips
Nvidia describes a metal cover that sits directly on top of electronic components to keep them cool. The design uses a liquid coolant that flows through channels on both the top surface and the side walls to remove heat from the chip.
In the filing’s own words
Examples of a coldplate for thermal management of electronic components are disclosed. In an example, a coldplate apparatus includes a body having a top structure and a sidewall, wherein the top structure and the sidewall form a receiving channel configured to be disposed over an electronic component, wherein the sidewall of the body includes a first opening, a second opening, and a sidewall conduit, wherein the sidewall conduit is configured to allow liquid to flow between the first opening and the second opening, and wherein the top structure includes a plurality of topside conduits that are configured to allow liquid to flow between the first opening and the second opening.
What exactly they claim (claim 1)
1. A coldplate apparatus comprising: a body having a top structure and a sidewall, wherein the top structure and the sidewall form a receiving channel configured to be disposed over an electronic component; wherein the sidewall of the body includes a first opening, a second opening, and a sidewall conduit, wherein the sidewall conduit is configured to allow liquid to flow between the first opening and the second opening; and wherein the top structure includes a plurality of topside conduits that are configured to allow liquid to flow between the first opening and the second opening.
