摘要:
Low-pressure drop thermal assemblies, systems and methods of making low-pressure drop thermal assemblies for use in high power flux situations. A manifold body is attached to a distributor to form a subassembly. This subassembly is in communication with a substrate surface, which has a semiconductor device in need of thermal management thereon. An enclosed cavity is formed between the target substrate surface and the subassembly, and a seal of the cavity protects critical components residing on the active surface of the semiconductor device. The distributor includes a distributed liquid impingement microjet inlet array isolated from and parallel with a distributed microjet drain array for impinging cooling fluid and removing spent heated fluid in a direction orthogonal to a target surface for maximizing the heat transfer rate, and thereby providing high cooling flux capabilities while enabling low-pressure drops.

Disclosed are thermally conductive plates. Each plate is configured such that a uniform adhesive-filled gap may be achieved between the plate and a heat generating structure when the plate is bonded to the heat generating structure and subjected to a temperature within a predetermined temperature range that causes the heat generating structure to warp. Additionally, this disclosure presents the associated methods of forming the plates and of bonding the plates to a heat generating structure. In one embodiment the plate is curved and modeled to match the curved surface of a heat generating structure within the predetermined temperature range. In another embodiment the plate is a multi-layer conductive structure that is configured to undergo the same warpage under a thermal load as the heat generating structure. Thus, when the plate is bonded with the heat generating structure it is able to achieve and maintain a uniform adhesive-filled gap at any temperature.
