A cooling hat for transferring heat from a surface or plurality of heat generating components to a flowing fluid includes a coldsheet, a plurality of manifold layers and springs. The coldsheet is typically a medium-thin metal sheet usually with fine fins or grooves to readily transfer heat to a coolant. Each manifold layer is typically molded rubber with conduits for coolant supply and return. The conduits form a branched hierarchy. The fluid flow is highly parallel and streamlined which achieves ample flow with small hydraulic differential pressure. Springs gently urge the cooling hat against the thermal joints hence against the components. The hat can bend slightly to conform to a curved surface. Typically some compliance is provided by the hat, and other compliance is provided by a thermal joint between each component and the coldsheet. The system is highly self-aligned for counteracting variations.
