  • Patent number: 10935330
    Abstract: A heat exchanger for regulating the temperature of objects includes two coolant ports that can interchangeably serve as either a coolant inlet or a coolant outlet. The heat exchanger includes sealedly engaged top, middle, and bottom plates that form passageways that distribute coolant through the heat exchanger. A top manifold is formed between the top and middle plates and is fluidly coupled with a first port, while a bottom manifold is formed between the bottom and middle plates and is fluidly coupled with a second port. The top and bottom manifolds are configured such that, during operation, coolant can be directed from the first port to the second port, or vice versa, thereby enabling the heat exchanger to operate bidirectionally—without materially affecting the temperature regulation effects of the heat exchanger. In this manner, the same heat exchanger construction can be used in multiple orientations within a thermal management system.

  • Patent number: 9671130
    Abstract: A water heater that can be operated with improved efficiency is provided. The water heater uses a thermally activated sorption heat pump to heat water stored in a tank. A sorbate is endothermically desorbed from a refrigerant, which in turn is released as a gas or vapor. The latent heat of condensing this refrigerant vapor to a liquid is transferred directly to the water in the tank. Ambient air is then used to vaporize the refrigerant liquid. The vapor refrigerant is then exothermically absorbed by the sorbate. The heat released by this absorption is transferred to the water in the tank using a heat transfer fluid. The cycle can then be repeated by desorbing the sorbate again to release the refrigerant as vapor. A heat source is used to provide heat energy to endothermically desorb the sorbate.

  • Publication number: 20010030040
    Abstract: A cryogenic heat exchanger has a pair of coaxial conduits. A pressurized refrigerant gas is passed through the internal conduit, out a thermal expansion valve and back through the annular space between the conduits. The closed end of the outer conduit is chilled by the expansion of the pressurized gas. The cryogenic effect is enhanced by precooling the pressurized warm gas with the depressurized cool return gas. A plurality of porous rings and disks bridging the lumen of the interior conduit and the annular space between the conduits assist in radial heat transfer to accomplish the desired precooling. The material chosen for the rings and disks is preferably highly porous, such as sintered metal, to increase the surface contact area and thereby increase heat transfer efficiency.

  • Patent number: 6283068
    Abstract: The present invention provides an air-heated/hot-water vaporizer having a very high thermal efficiency and which is easy to handle for a long period of time. Hot water supplied to the inner tube 24 of the hot water tube 22 passes through the inner tube 24 and flows out from the other end thereof to the closed end side of the outer tube 23. The hot water having flowed out to the closed end side of the outer tube 23 passes through the annular path formed by the inner tube and the outer tube 23, flows in a direction counter to that of the hot water flowing in the inner tube 24, and flows from the opening of the outer tube 23 to the outside. Liquefied gas supplied to the liquefied gas tube 21 flows along the outside of the outer tube 23, and is heated and vaporized by hot water flowing through the hot water tube 22.

  • Patent number: 6139315
    Abstract: A recuperator for furnaces includes a set of tubes, which are installed in a secondary chamber (1) which is located behind a main combustion chamber of the furnace and through which hot fumes can pass from the main combustion chamber towards an outlet. The task of the tubes is to recuperate thermal energy from the fumes by bringing a combustion gas to pass through the tubes on its way to burners in the main combustion chamber. The different tubes of the tube set are designed as individual units (8) each one of which is removably inserted in the secondary chamber (1) through holes in the walls (4) thereof. In the mounted condition each tube has a closed portion projecting into the secondary chamber as well as a portion projecting from the outside of the walls of the secondary chamber, the latter portion having inlets and outlets for cold and preheated combustion gas respectively.

  • Patent number: 6019598
    Abstract: A recuperator of simple design constructed from a hollow tube. A penetrating tube is formed of a hollow tube, preferably of stainless steel, closed at one end and open at the other end. The open end is cut and welded, or otherwise secured, to a perpendicular hollow tube which introduces and expels ambient air. A divider wall is disposed within the penetrating tube to force introduced ambient air along the length of the penetrating tube before exiting the recuperator. This arrangement exposes the ambient air to the heated surface of the penetrating tube along its entire flow path, substantially twice the length of the penetrating tube. A spiralled strip of 14 gage stainless steel may be disposed within the penetrating tube to enhance heat exchange between the penetrating tube and ambient air flowing there within.

  • Patent number: 5954128
    Abstract: Many recuperators have components which react to corrosive gases and are used in applications where the donor fluid includes highly corrosive gases. These recuperators have suffered reduced life, increased service or maintenance, and resulted in increased cost. The present header assembly when used with recuperators reduces the brittle effect of a portion of the ceramic components. Thus, the present header assembly used with the present recuperator increases the life, reduces the service and maintenance, and reduces the increased cost associated with corrosive action of components used to manufacture recuperators. The present header assembly is comprised of a first ceramic member, a second ceramic member, a reinforcing member being in spaced relationship to the first ceramic member and the second ceramic member.

  • Patent number: 5830515
    Abstract: A mold insert for an injection molding machine has a circumferential liquid conduit groove and a plurality of liquid-receiving bores extending inwardly from the groove. Baffles are removably inserted into the liquid-receiving bores and have heads located in locking engagement with the sidewalls, including the undercut portions thereof, to retain the baffles in their respective liquid-receiving bores. Each baffle has a blade that fits snugly within a liquid-receiving bore to separate the liquid-receiving bore into a liquid inlet passageway and a liquid outlet passageway. Fins project outwardly from opposite faces of the blade to create turbulence in liquid flowing into and out of the liquid-receiving bore, which enhances cooling (or heating) of the mold insert. The baffle is also useful with other solid components having a liquid conduit for cooling purposes and a transverse liquid-receiving bore intersecting the liquid conduit.

  • Patent number: 5791370
    Abstract: An apparatus for supplying fluid comprising a fluid source, valve, inside tube and outside tube. The outside tube is in open communication with the fluid source and the valve. The inside tube is located within the outside tube. The inside tube is in open communication with the fluid source on one end and is spaced apart from the valve on the opposite end so that warm lower density fluid from the fluid source flows up through the inside tube displacing cool higher density fluid near the valve. The cool higher density displaced fluid is forced by gravity back to the fluid source in a fluid return path located between the inside tube and the outside tube. When the valve is in the closed position for an extended period of time, the apparatus maintains a continuous fluid flow from the fluid source through the inside tube to a location near the valve. When the valve is opened warm fluid flows immediately through the valve saving both time and fluid.
