Abstract
Systems and methods are provided for a gasket that allows for a single cooling cold plate to touch one or more devices. These devices may have precise but varying thermal interfaces and mounting pressure requirements; and height and co-planarity tolerances that need to be accommodated. The gasket may be sandwiched in between a top stiffener plate and a floating cold plate along an outer perimeter of the gasket; and a rigid, cold plate base and a bottom stiffener plate along an inner perimeter of the gasket. The resulting seal allows coolant to flow between the rigid and floating cold plates as these plates move (i.e., float) with respect to one another. Thus, the gasket aids in a cooling apparatus achieve an optimum thermal interface with each of the one or more devices simultaneously, while accounting for the individual tolerance variations across each device.
