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.

摘要： A CPU cooling assembly having a first, covering layer of conductive material above the upper surface of an enclosed, heat producing chip and a third, upper layer of conductive material (a heat sink base plate) thermally bonded to the first by an intermediate, second layer of thin, conforming material (thermal grease) that is far less thermally conductive, and more resistive, than the other two layers. The relative thickness relationship of the first and third, more conductive, layers is essentially reversed from the prior art, with first layer being relatively thicker than the third. This creates an overall lower resistance for the three layer sandwich.

摘要： A heat sink removes heat from an electronic device and comprises a base, a lid. An inner ring of first fins extend radially outwardly first length from an inner circle and extend axially a first height from the top surface of the base, and an outer ring of second fins extend radially inwardly a second length from an outer periphery and extend axially a second height from the top surface of the base. A confining plate extends radially above the fins and is spaced below the bottom surface of the lid whereby coolant fluid flows from an inlet opening of the lid through the center opening of the confining plate and radially outwardly through the fins and upward around the outer edge of the confining plate and into the space above the confining plate to an outlet opening. A nozzle having a throat is disposed above the lid and extends below the lid to the confining plate. A flow diverter extends upwardly from the top surface of the base and into and through the throat of the nozzle.
