    摘要: A high efficiency thermal interposer comprising a first hollow disk and second hollow disk, held together by thermally isolating fasteners. The fasteners keep the disks from touching one another. In an illustrative embodiment of the invention, the first disk is the low temperature disk portion and the second disk is the high temperature disk portion of the heat shield. Furthermore, according to a preferred embodiment of the invention, the space between the disks is filled with small thermally conductive particles (e.g., stainless steel spheres) which are in thermal contact with the high temperature disk; but which are not in contact with the low temperature disk. The thermal interposer/heat shield includes means for introducing cold jets of air into the cavity containing the particles, means for circulating the air therebetween, and means through which the air can exit from the cavity to carry away the heat picked up from the particles inside the cavity. The novel thermal interposer has a low mass, is compact and can achieve a temperature drop that will permit high powered HAT devices to be used in conjuction with temperature sensitive electronic orientation means, such as robot arms.

    摘要: The invention provides lightweight packaging of portable electronic apparatus by using the combined structural properties of an enclosure, that houses the interwired heat producing electronic signal devices of the apparatus, to provide coolant movement and direction, locally selectable physical protection and shock resistance and electrical shielding. It achieves the packaging benefits by having; a laminated enclosure member structure that has an internal device supporting lamination and an external wear resistant lamination on each side of a layer of a material that has the combined physical properties of selectably interrelated coolant permeability and density, non-corrosiveness and electrical conductivity; heat generating signal processing devices mounted on the internal lamination; positioned holes through the laminations on each side of the permeable material layer that provide entrance, exit and directing openings for a coolant fluid, including air, that is brought in from the outside, and, propelling the coolant at least conventionally by the heat from the signal processing devices and additionally by a separate fan located in the enclosure so that the heated coolant is exhausted to the outside. Localized shock resistance is imparted by selective change in the density of the permeable layer.
