    Abstract: An improvement in atmospheric evaporative water condenser is disclosed. The apparatus includes tubes through which a refrigerant would pass and a variety of generally rectangular or circular fins are in contact with the tubes which causes the fins to cool. This permits water in its vapor form which exists in atmospheric air to condense on the fins and the condensate is collected as potable water. The improvement includes a plurality of different width spacers which are toleranced to be placed over the tubes and secured in desired positions. The fins are placed between the spacers allowing different fin spacing configurations on the apparatus. The different fin configurations optimize airflow for different coil and fin sections and help prevent water flooding or frost buildup on the fins which impair efficiency. Also, the spacers allow the fins to be placed far enough apart that non-frozen condensate does not block the air flow through the space between the fins.

  • Patent number: 8253076
    Abstract: A heater unit for a respiratory system is designed for natural convection cooling air to pass first through a transformer in the heater unit and then through a heat sink in the heater unit to which is mounted a power switch to conduct heat from the power switch to the cooling air passing through the heat sink. A thermal break may be provided between the heat sink and the transformer. The transformer may be a toroidal transformer with the air passing through an aperture thereof such as from a hollow projection of the heater unit extending into the aperture. One side of the transformer may be situated along a surface of the heater unit and the heat sink secured to the heater unit against the opposite side of the transformer to hold the transformer in place. A venting chamber may be associated with an air exhaust of the heater unit to provide a circuitous exit path for air exiting the heater unit. The venting chamber may extend in generally surrounding relationship with the heater of the heater unit.

  • Patent number: 8225846
    Abstract: A radiating fin assembly includes a plurality of alternately stacked first radiating fins and second radiating fins, such that a V-shaped recession is formed between any two adjacent first and second radiating fins. The V-shaped recessions are defined on at least one of two longitudinal sides of the radiating fin assembly and include a plurality of split spaces, first widened spaces, and second widened spaces. The split spaces are formed at a bottom portion of the V-shaped recessions, and the first and the second widened spaces are formed at two opposite ends of the split spaces. The radiating fin assembly can be associated with at least one heat pipe and a base to form a thermal module. With the V-shaped recessions, the radiating fin assembly and the thermal module can have widened airflow inlets, shortened airflow paths, reduced airflow pressure drop and flowing resistance, and accordingly upgraded heat dissipating efficiency.

  • Publication number: 20120012293
    Abstract: A liquid-loop compound recuperator is disclosed for high-? heat exchange between a first shell-side fluid stream and a second shell-side fluid stream of similar thermal capacity rates (W/K). The compound recuperator is comprised of at least two fluid-to-liquid (FL) recuperator modules for transfer of heat from a shell-side fluid, usually a gas, to an intermediary tube-side heat transfer liquid (HTL). Each FL module includes a plurality of thermally isolated, serially connected, adjacent exchanger cores inside a pressure vessel. The cores are rows of finned tubes for cross-flow transfer of heat, and they are arranged in series to effectively achieve counterflow exchange between the HTL and the shell-side stream. The HTL may be water, an organic liquid, a molten alloy, or a molten salt. Alumina-dispersion-strengthened-metal fins, superalloy tubes, and a lead-bismuth-tin alloy HTL may be used for high temperatures. Cumene may be used as the HTL in cryogenic applications.
