A heat exchanger includes a plurality of fins arranged as a network and delimiting corridors, and an envelope having an internal wall and an external wall, the internal and external walls delimiting between them a channel for a flow of a first fluid in a main direction, the network of fins being arranged in the channel and connected to the internal and external walls, at least one passage for a flow of a second fluid being embedded in at least one of the internal and external walls, the channel being, in the main direction, divergent and then convergent.

A two-phase immersion type heat dissipation fin composite structure is provided. The two-phase immersion type heat dissipation fin composite structure includes a heat dissipation base layer, a bubble activation layer, and a fin structure. The fin structure and the bubble activation layer are both formed on the heat dissipation base layer, or the fin structure is formed on the bubble activation layer. The bubble activation layer is immersed in a two-phase coolant for increasing an amount of bubbles that is generated.

A heat sink for use in an immersion cooling system that includes a sintered powder structure enclosed in a porous enclosure. The porous enclosure has openings, e.g., formed by a mesh, with a size to help contain sintered powder particles that may be dislodged during operation of the heat sink.

A heating module for a substrate processing chamber includes heating lamps coupled to a reflector plate and a heat exchanger. The heat exchanger cools a gas within the heating module. A fan within the heating module circulates the gas through apertures in the reflector plate to cool the heating bulbs. The gas is cooled by the heat exchanger, and is recirculated. One or more shrouds directs the gas as the gas is being circulated.

An apparatus and method for generating a three-dimensional object. The apparatus includes a build material area, at least one agent distributor with a fluid reservoir to store fluid agent and at least one fluid ejection die to selectively eject fluid agent in the build material area. A cooling system to remove heat from the at least one fluid ejection die has a heat sink. The at least one fluid ejection die is in thermal contact with the heat sink via the fluid agent of the fluid reservoir.

A transmission-mountable transmission cooler and method of installing and manufacturing the same is provided. The transmission cooler is adapted to couple directly to the transmission via a power take-off aperture typically found on manual truck transmissions. As a result, the transmission cooler may be made from an extruded aluminum piece to which tool and die making has provides a bolt pattern that matches the bolt pattern of a standard power take-off cover of the power take-off aperture, resulting in a cost-effective method of installation and in turn manufacture.
