Abstract: A heatsink having enhanced localized cooling. The heatsink comprises a wall; a heatframe; a coolant channel between the wall and the heatframe, wherein a bulk coolant flows through the coolant channel; and one or more nozzles that extend into the coolant channel and proximate the wall and/or the heatframe, wherein a high-pressure coolant flows through the one or more nozzles, mixes with the bulk coolant in the coolant channel, and impinges on a cooling area of the wall and/or the heatframe proximate an outlet of the one or more nozzles to provide enhanced localized cooling to at least a portion of a heat producing device that is proximate to or in partial contact with the wall and/or the heatframe proximate to the cooling area of the wall and/or the heatframe.

Abstract: A cooling module comprising a porous media that is at least partially inserted into a coolant channel of a heatsink. Generally the coolant is a liquid, though in some instances it may be a gas. More specific, a cooling module for providing enhanced localized cooling of a heatsink comprising a porous media having a volume and a seal plate connected to the porous media, wherein a portion of the volume of the porous media extends through a wall and/or a heatframe of the heatsink into a coolant channel such that coolant flows through the porous media extending into the coolant channel. The seal plate provides a seal for the wall and/or the heatframe so that the coolant does not flow out the wall and/or the heatframe. The seal plate provides enhanced localized cooling to a heat producing device that is at least in partial contact with the seal plate.

Abstract: A circuit card assembly comprising at least one electronic component that generates heat and a thermal management system the at least one electronic component is disclosed. The thermal management system comprises one or more phase change modules for distributing and storing heat; a metal frame in thermal contact with the at least one electronic component and having at least one opening for receiving the one or more phase change modules; and a heat transfer apparatus in thermal contact with one or more of the at least one electronic component and the metal frame. The heat transfer apparatus comprises at least one heat pipe and/or at least one heat spreader. The heat transfer apparatus provides a first heat transfer path during a period of reduced heat dissipation or cooling. The one or more phase change modules distributes and stores heat during the period of reduced heat dissipation or cooling.

Abstract: The cooling assembly includes: a heat sink base thermally coupleable with a heat-generating component to be cooled; cooling fins thermally connected with the heat sink base to provide a thermal path from the heat-generating component to the cooling fins; and a displacement mechanism operable to reciprocate the cooling fins.
