  • Patent number: 7954321
    Abstract: A method for storing heat from a solar collector CSTC in Concentrating Solar Power plants and delivering the heat to the power plant PP when needed. The method uses a compressed gas such as carbon dioxide or air as a heat transfer medium in the collectors CSTC and transferring the heat by depositing it on a bed of heat-resistant solids and later, recovering the heat by a second circuit of the same compressed gas. The storage system HSS is designed to allow the heat to be recovered at a high efficiency with practically no reduction in temperature. Unlike liquid heat transfer media, our storage method itself can operate at very high temperatures, up to 3000° F., a capability which can lead to greater efficiency. Due to material constraints and cost considerations in the rest of the system the maximum temperature is presently limited to between 1700° F. and 2000° F. The method can be applied to all current solar collector designs.

  • Patent number: 6848500
    Abstract: The invention discloses an apparatus for reducing peak temperatures and thermal excursions, of semiconductor devices, particularly in pulsed power applications. The apparatus comprises thermally coupling Phase Change Material (PCM) to the dissipating semiconductor device. PCM absorbs heat and stays at a constant temperature during its phase change from solid to liquid. The PCM melting point is chosen so that it is just below the temperature the device would otherwise achieve. When the device approaches the maximum temperature, the PCM melts, drawing heat from the device and lowering the device's peak temperature. As the device stops dissipating, after its pulse period, the PCM material solidifies releasing the heat it absorbed. The apparatus lowers the peak temperature by absorbing heat when the device is dissipating.

  • Patent number: 6772823
    Abstract: A heat storage device comprises a heat storage tank 2 charged with a heat storage material 1 for storing the heat supplied from the outside, and a heat exchanger 3 for executing an injection and an extraction of heat between the inside of the storage tank 2 and the outside by the heat exchange between the heat storage material and a heat transfer medium. The heat exchanger 3 is disposed so as to execute a heat exchange between the central portion 2a in the heat storage tank 2 and the outside, and suppresses the natural convection of the heat storage material 1 of the outer portion 2b by, for example, dispersing a liquid-absorbent material 5 in the outer portion 2b surrounding the central portion in the heat storage tank 2, whereby reduces the influence of external environment on the central portion 2a in the heat storage tank, thereby suppressing the heat loss toward the outside.

    Abstract: The increase of temperature of heat sensitive devices during heat generating conditions is prevented through the absorption of heat, by providing boric acid in an amount sufficient to effect the required heat absorption. Where the heat generating conditions are generated by a heat generator, separate and distinct from the heat sensitive device, the boric acid may be supported in a position between the heat sensitive device and the heat generator. Where the heat sensitive device is itself the heat generator, the boric acid is in contact with the heat sensitive device, either directly or indirectly.

  • Patent number: 6698510
    Abstract: A temperature regulation and flow control device is described. A web of material, e.g., for a wet suit, has a layer of gel particles embedded in a flow control layer, preferably a foam matrix. A water permeable neoprene layer covers the flow control layer and allows water to enter the suit. The flow of water in the suit is regulated by the expansion and contraction of the gel as it undergoes a volume phase transition in response to a change in temperature. When the diver is in cold water, the cold water enters the foam substrate and the gel expands, causing permeability (i.e., flow) to decrease. Flow is restricted in response to cooling, and the foam substrate expands and tightens the fit of the wet suit. In warmer water, an opposite effect occurs, whereby the gel contracts and flow increases. The gel contracts relaxing the fit of the suit. A gel having a particular volume phase transition critical temperature is selected in order to maintain body temperature in a particular environment.

An insulated outer shell is spaced from the inner vessel to define an interstitial chamber between the inner vessel and the outer shell.

  • Patent number: 6631755
    Abstract: A thermal module with temporary heat storage. The thermal module includes a heat storage, a heat absorber, a heat dissipater, and a heat pipe for rapidly transferring heat from the heat absorber to the heat dissipater. The heat storage includes a phase change material and is in contact with the heat pipe. When heat quantities generated by the system are greater than a predefined reasonable thermal target, heat in excess of the thermal target is temporarily absorbed into the heat storage through the melting of the PCM. When the heat quantities generated by the system are again less than the thermal target, the PCM re-freezes, releasing the stored heat to be dissipated normally.
