  • Patent number: 11885541
    Abstract: Refrigeration cycle intercooler with dual coil evaporator is a component in a refrigeration cycle that is installed in a vehicle with an internal combustion engine or motor. The refrigeration cycle operates by continuously cycling a refrigerant through a closed loop where refrigerant passes through an inner coil evaporator and an outer coil evaporator where the refrigerant changes from liquid to gas, thereby providing a cooling effect. During operation, fresh air or outside air continuously passes by the inner coil evaporator and the outer coil evaporator and then continues into the internal combustion engine or motor air intake. The inner coil evaporator and the outer coil evaporator function to cool and dry the intake air for the internal combustion engine or motor. The inner coil evaporator and an outer coil evaporator are specially designed to provide substantially more cooling and drying than any other intercooler design.

  • Patent number: 11699532
    Abstract: Arrangement for supporting U-bend tube sections in the high heat environment of steam generators using flat bars. The invention uses a combination of thicker and thinner flat bars to impart a serpentine path to the arc of the normally curvilinear U-tubes. The support system accommodates the dilation and contraction of coolant tubes and other elements caused by the extreme and varying conditions inside a steam generator, and which can cause gaps between coolant tubes and prior art tube support bars. Bars of alternating thickness provide alternating offsets to tensionally push and support each tube on multiple sides and in multiple locations, and this tension keeps the tubes in contact with at least some flat bars on multiple sides regardless of size and shape changes. Support arrangement includes a set of fan bars, each fan bar including thick and thin flat bars projecting up and out from a collector bar.

  • Patent number: 11662127
    Abstract: A present heating system or heating and cooling system does not include a tank for storing potable hot water in anticipation of a potable hot water demand. Although one or more temperature sensors may be used for providing feedback to heating of the contents of a tank water heater to achieve a setpoint temperature, the effect of stratification can cause layers of fluid having different temperatures in the tank water heater. Therefore, although portions of the contents of a water heater may be disposed at a setpoint temperature that is unfavorable for Legionella proliferation, there potentially exists other portions that may be disposed at temperatures suitable for Legionella proliferation, especially when the contents have been left unused for an extended period of time.

  • Patent number: 11306971
    Abstract: A heat exchanger for abating compounds produced in semiconductor processes. When hot effluent flows into the heat exchanger, a coolant can be flowed to walls of a fluid heat exchanging surface within the heat exchanger. The heat exchanging surface can include a plurality of channel regions which creates a multi stage cross flow path for the hot effluent to flow down the heat exchanger. This flow path forces the hot effluent to hit the cold walls of the fluid heat exchanging surface, significantly cooling the effluent and preventing it from flowing directly into the vacuum pumps and causing heat damage. Embodiments described herein also relate to methods of forming a heat exchanger. The heat exchanger can be created by sequentially depositing layers of thermally conductive material on surfaces using 3-D printing, creating a much smaller footprint and reducing costs.

    Abstract: A system for transferring and heating fluid is disclosed comprising a fluid transfer pipe having an internal surface and an external surface, and at least one helical heating rib connected to the internal surface of the fluid transfer pipe structured and arranged to generate non-laminar flow and to heat the fluid as it flows through the fluid transfer pipe. A method of heating fluid contained in a pipe is also disclosed. The method comprises providing at least one helical heating rib connected to an internal surface of a fluid transfer pipe, and passing the fluid through the fluid transfer pipe, whereby the at least one helical heating rib generates turbulent flow of the fluid to thereby heat the fluid. The helical heating ribs may comprise hollow channels through which a heating liquid may be passed to further heat the fluid contained in the pipe.

  • Publication number: 20140319672
    Abstract: Channel members 100 to 107 according to the present invention have an inner spiral channel 9 through which a fluid 23 flows. The channel 9 is formed by a lid part 1, a bottom plate part 3, and a wall part 2 connected to the lid part 1 and the bottom plate part 3. The wall part 2 is made of a ceramic laminate. Even if the wall part 2 of the channel members 100 to 107 is narrow between channel segments 9, its good corrosion resistance allows the channel 9 to be resistant to collapse when the fluid 23 is supplied at high pressure. A heat exchanger 200, a semiconductor unit 300, and a semiconductor manufacturing apparatus 400 including any of the channel members 100 to 107 have improved heat exchange efficiency between the channel members 100 to 107 and the fluid 23.
