摘要： A heat dissipation element for cooling an electronic device is disclosed. The heat dissipation element has a top surface and a bottom surface for mounting the electronic device to be cooled thereto. The top surface defines a heat dissipation area for dissipating heat from the electronic device and a plurality of heat transfer fins project upwardly from the top surface and are coextensive with the heat dissipation area. Each of the heat transfer fins defines a plurality of steps having a rise and a run and each of the steps extend across the heat dissipation area for maximizing an amount of heat dissipated from the electronic device. The heat dissipation element is particularly useful in either one of a cold plate assembly used with a liquid cooled unit (LCU) or a boiler plate assembly used with a thermosiphon cooling unit (TCU).

摘要： A thermosiphon assembly for dissipating heat generated by an electronic component using a working fluid is disclosed. The assembly includes an evaporator having a front face, a rear face, and a peripheral wall extending between the front face and the rear face and being arcuate. A heat block contacts the front face for transferring generated heat from the electronic component to the working fluid to vaporize the working fluid. A condenser is in fluid communication with the chamber and connected to the rear face for condensing the vaporized working fluid back to a liquid. The assembly further includes an acute angle between the front face and the peripheral wall such that the chamber extends upwardly at an angle from the front face to the rear face to ensure complete coverage of the heat block with the cooling fluid in any position between horizontal and vertical.

摘要： An evaporative heat exchanger for cooling a hot refrigerant having a core of alternatively stacked dry and wet plates. Each dry plate includes a dry side defining a plurality of dry channels in a first direction, a series of ports distributed along the dry channels, a wet side, and a refrigerant cooling section. Each wet plate includes a wet side adjacent to and cooperates with the wet side of the dry plate to define a plurality of wet channels in a second direction. The dry channels, ports, and wet channels define a labyrinth for the air flow, which evaporates the liquid contained in the wet channels resulting in a cooling of the refrigerant. The refrigerant cooling section is integral with the outboard of the dry plate and adjacent to an end section of the wet channels to provide enhanced refrigerant cooling.
