  • Patent number: 8714461
    Abstract: Devices utilized to enhance insulating properties at high temperatures. Such devices can include two gas compartments. A main gas compartment can function as a main layer and generally contains a layer of a gas (e.g., Xenon) having a relatively small thermal conductivity. The plates of the main gas layer can be separated by a soft seal, so that the main gas does not leak and the main layer expands easily. A second gas compartment can be configured as a vented compartment filled with air. At high temperatures, the main gas expands while the secondary gas volume shrinks. Since the main gas possesses a lower thermal conductivity, the effective resistance of the device increases, causing an enhancement in the insulating properties at large operating temperatures. A series of gas compartments can be utilized for additional enhancement in insulating properties.

Both the upper plate of the secondary layer and the lower plate of the main layer are fixed while the intermediate plate and is free to move in the vertical direction. When the pressure or the working temperature in the secondary layer increases, the secondary layer expands causing the main layer thickness to shrink.

  • Patent number: 8684275
    Abstract: Devices and methods for increasing and decreasing cooling capacity as thermal load increases by utilizing bimaterial. For increasing the cooling capacity, the upper plate of a thin film microchannel can be configured from a bimaterial, such that the upper layer possesses a higher linear thermal expansion coefficient than that of the lower layer material. Excessive heating causes the coolant temperature to increase which in turn heats the upper plate. As such, the upper plate bends outward allowing for more coolant to flow within the thin film. For decreasing the cooling capacity, the upper plate can be configured from a bimaterial such that its lower layer has a higher linear thermal expansion coefficient than that of the upper layer material. Excessive heating can cause the coolant temperature to increase, which in turn heats the upper plate. As such, the upper plate can bend inward resulting in less coolant flow within the thin film.

  • Publication number: 20130105117
    Abstract: According to the present invention, the method of heat transfer in a direction, which is reverse to natural convection, includes introduction of an additional pumping substance into the heated area. The pumping substance is incapable to be dissolved in the heat-transfer agent and its boiling temperature is lower than the boiling temperature of the heat-transfer agent. The heat-transfer agent is heated up, the pumping substance evaporates and the vapour pressure of the pumping substance is used to force the hot heat-transfer agent to flow along the branches of the circulating loop. The device for heat transfer in a direction reverse to the natural convection characterized in that its design incorporates technical means intended for vapour condensation of the pumping substance as well as technical means intended for draining that condensate from the condensation area to the evaporation area.

  • Publication number: 20130056176
    Abstract: The heat exchanger with a controlled coefficient of thermal expansion (CTE) includes a low CTE thermal expansion control member operatively connected to a heat transfer member in order to restrain the lateral thermal expansion of the heat transfer member during use. The thermal expansion control member is placed outside the heat transfer path, so the thermal expansion control member can be made of a low thermal conductivity material without increasing the thermal resistance of the heat exchanger. The CTE of the thermal expansion control member is lower than that of the heat transfer member, so as to constrain lateral thermal expansion of the heat transfer member during operation. The difference between the CTE of the device being cooled and the heat transfer member, i.e. the CTE mismatch, is reduced over conventional heat exchangers by restraining the heat transfer member during operation.

    Abstract: A microchannel heat exchanger (800) is manufactured by bonding a first sheet (802a) of material and a second sheet (802b) of material in a first connection pattern for integral formation of a core portion (801) and a manifold portion (808) for the first and second sheets (802a, 802b) of material. A third sheet (802c) of material is then superposed on to the second sheet (802b) of material and bonded in a second connection pattern to the second sheet of material for integral formation of the core portion (801) and the manifold portion (808) for the second and third sheets (802b, 802c) of material. The second and third sheets (802b, 802c) of material are bonded without bonding the second sheet (802b) of the material to the first sheet (802a) of material. The core portion (801) and the manifold portion (808) of the heat exchanger (800) are thus integrally created. The interstices between the first, second, and third sheets (802a, 802b, 802c) of material are then expanded to create fluid flow channels (806).

  • Patent number: 8313706
    Abstract: Provided are a gasket, a reactor using the same for sealing a spiral, and a manufacturing method thereof. Spirials are continuously installed in the longitudinal direction between an inner pipe and an outer pipe coaxially arranged to form a flow path for a heat medium, so the seal between the spiral and the outer pipe is stably maintained and fabrication of the reactor is facilitated. The gasket is inserted in and coupled with the spiral, and thus does not need additional processing for combining the gasket. The gasket and spiral are coupled by lodging the spiral into a channel of the gasket. Furthermore, since the gasket is evenly coupled in the outer circumference of the spiral, in which a cushion plate made of resilient material is installed, breakage of the gasket during assembly of the outer pipe is effectively prevented and the post-assembly seal between the spiral and the outer pipe is stabilized.
