US Classification:

16510421, 165 803, 16510433

Abstract:

A plate is thermally coupled to a heat generating device and thermally coupled to two heat pipes. Each heat pipe is configured to have a predetermined boiling point temperature selected according to design criteria. One or more additional heat pipes can be coupled to the plate. A heat spreader can be in thermal contact with the heat generating device and with at least one of the heat pipes. The heat pipes can differ in outer cross-sectional dimensions depending on thermal distance position relative to the heat generating device, such that the heat pipes located a farther thermal distance from the heat generating device have smaller outer cross-sectional dimensions than the heat pipes located a shorter thermal distance from the heat generating device.

Abstract:

A method of controlling temperature of a heat source in contact with a heat exchanging surface of a heat exchanger, wherein the heat exchanging surface is substantially aligned along a plane. The method comprises channeling a first temperature fluid to the heat exchanging surface, wherein the first temperature fluid undergoes thermal exchange with the heat source along the heat exchanging surface. The method comprises channeling a second temperature fluid from the heat exchange surface, wherein fluid is channeled to minimize temperature differences along the heat source. The temperature differences are minimized by optimizing and controlling the fluidic and thermal resistances in the heat exchanger. The resistances to the fluid are influenced by size, volume and surface area of heat transferring features, multiple pumps, fixed and variable valves and flow impedance elements in the fluid path, pressure and flow rate control of the fluid, and other factors.

Abstract:

An apparatus and method of circulating a heat-absorbing material within a heat exchanger. The apparatus comprises a manifold layer coupled to an interface layer. The manifold layer comprises an inlet manifold and an outlet manifold. The interface layer comprises a plurality of channels that extend from the inlet manifold, toward a heat-exchanging plane, and turn away from the heat-exchanging plane, terminating at the outlet manifold. The plurality of channels are stacked in a plane non-parallel to the heat-exchanging plane. Each of the channels is adjacent to another, thus allowing heat radiated from a heat-generating device to be conducted to a cooling material circulating within the channels, away from the heat-generating device. Preferably, each of the channels has a U-shape or an elongated U-shape.
