Solution Approach 1:

The cooling system is divided into separate modular components: a cold plate assembly that interfaces with the heat source and a radiator assembly that dissipates heat. These modules can be independently configured and replaced for different applications without affecting the entire cooling system.

Inventive Principle:

Solution Approach 2:

The cold plate assembly is designed as a universal interface that can be adapted to multiple different heat source configurations and component types. The standardized mounting and thermal interface allow the same cold plate to serve various components, enhancing system versatility.

Solution Approach 1:

The system replaces air-based cooling with liquid-based cooling, using a closed-loop liquid cooling system that efficiently transports heat away from the adapter card to a separate radiator location. This hydraulic cooling approach removes heat from the chassis internal environment while maintaining effective component cooling.

AI summary

A thermal interposer for a heat-generating electronic component located on an adapter card of a computer includes a thermally conducting planar body. The thermally conducting planar body may be configured to be coupled to the adapter card such that a first surface of the planar body is in thermal contact with a surface of the electronic component. The thermal interposer may also include a cold plate assembly removably coupled to a second surface of the planar body opposite the first surface. The cold plate assembly may include an inlet adapted to receive a cooling liquid into the cold plate assembly and an outlet adapted to discharge the cooling liquid from the cold plate assembly.
