摘要： A heat exchanger assembly for cooling an electronic device comprises a flange, a dome, a plurality of condensing tubes, a shroud and a boiler plate. The dome is semi-cylindrical in shape with flat axial ends. A plurality of spaced condensing tubes is disposed in a plurality of fan rows with each fan row being in a fan plane to facilitate more-efficient heat transfer. The distal ends of each of the condensing tubes are elongated along the associated fan plane to define the fan rows in a fan shape. In other words, each fan row contains one elongated, fan-shaped condensing tube. The condensing tubes in adjacent fan planes terminate in an arch extending concentrically about the center axis at the flat axial ends of the semi-cylindrical dome. The pattern of the elongated condensing tubes resembles the erectile ribs of an igloo.

摘要： Two embodiments of a heat exchanger assembly for cooling an electronic device are shown respectively in FIGS. 1 and 3 and each comprises a housing, a plurality of high fins, a plurality of low fins, a nozzle plate, an inlet, at least one outlet, a primary nozzle, and a plurality of secondary nozzles. In the first embodiment shown in FIG. 1, the housing and the nozzle plate are circular in shape. In the second embodiment shown in FIG. 3, the housing and the nozzle plate are rectangular in shape. Both embodiments include a plurality of secondary nozzles that are aligned outwardly of the primary nozzle and the center axis of the nozzle plate. The secondary nozzles direct the flow of the cooling liquid outwardly of the primary nozzle from the center thus creating an overall system pressure drop lower than that of other assemblies without a plurality of secondary nozzles.

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： A cooling assembly having a base plate and a condenser plate. An outer wall interconnects the base plate to the condenser plate to define a sealed chamber with a working fluid being disposed within the sealed chamber. Intersecting partition walls are mounted to the condenser plate and are angled downwardly toward the base plate for directing working fluid on the condenser plate down a corner of the walls toward a portion of the base plate. Preferably, the base plate defines a first circumference and the condenser plate defines a second circumference larger than the first circumference such that the outer wall has an angled configuration extending between the base plate and the condenser plate to provide a larger area within the sealed chamber for a vapor phase of the working fluid than a liquid phase of the working fluid.
