  • Patent number: 9605912
    Abstract: A heat exchanger for transferring heat between two fluids consists of a shell surrounding at least two tube bundles attached at both ends to a tube header. Each of the tube bundles is constructed from a plurality of individual tubes that are twisted into identical helixes formed about a common helical axis. Because each individual tube is formed in the shape of a helix, rather than as a straight tube, thermal elongation of the individual tubes results in a considerably reduced axial force on the tube attachments and tube header. Use of multiple tube bundles wound with opposite twist direction improves spacing efficiency between tubes.

This is obtained by having pumping means for displacing the substance, exchanging heat between a heat exchanger and the substance, displacing substance with the pumping means for increased heat exchange between the heat exchanger and the substance, as well as stirring the substance with the pumping means by displacing the substance inside the container. When the substance is displaced, then not only stagnant substance is in contact with the heat exchanger for heat exchange. The amount of substance in contact with the heat exchanger is thereby greatly increased, and the heat transfer is less dependent on thermal conductivity of the substance.

  • Publication number: 20100018685
    Abstract: The invention relates to a fluid reservoir having a sorption medium. An energy absorbing and/or releasing device is provided for the improvement of the energy balance and for an immediately accessible heat supply from the sorption medium, for the gas release process, during the extraction of fuel from the fluid reservoir. For the intermediate storage of thus transferred energy in the form of differential heat between the filling and emptying of the fluid reservoir, the use of a latent heat reservoir, especially materials having melting temperatures of between 0° C. and 1400° C., is preferred. The use of such a latent heat reservoir enables permanent sufficient supplies of immediately accessible energy for a sufficient fluid extraction from the fluid reservoir, such that a flawless operation of an energy converter operated using the fluid, e.g. in the form of a fuel cell or a gas motor, is always ensured, especially in the event of low ambient temperatures.

  • Publication number: 20090126915
    Abstract: A header for a heat exchanger orients the position of an inlet port at an angle offset from the position of the outlet port on the header body in order to simplify the plumbing of the header within a system. In one implementation of a header for a heat exchanger, the header forms a header cavity defined by an external wall and which is separated into an inlet chamber and an outlet chamber by a dividing wall. An inlet port is defined within the external wall and is in fluid communication with the inlet chamber. Similarly, an outlet port is defined within the external wall and is in fluid communication with the outlet chamber. The inlet port is oriented on the external wall at an offset angle with respect to a position of the outlet port.

  • Publication number: 20090114378
    Abstract: A heat exchanger comprises an evacuated reaction chamber (2, 2?, 23, 33) containing at least one reaction medium and a storage chamber (25, 35) containing an activation medium which reacts with the reaction medium in such a way as to modify the temperature. The reaction chamber and the storage chamber can be brought into a communicating relationship, whereby the reaction medium and the activation medium are contacted with each other and the temperature-modifying reaction is triggered. The reaction chamber (2, 2?, 23, 33) is defined by walls made of a vacuum-tight material (3), which walls are kept at a distance from each other, at least in sections, by supporting bodies (4, 7, 10), with the supporting bodies (4, 7, 9, 10) keeping free transport paths (5, 8) for the reaction medium (11) inside the reaction chamber. The vacuum-tight material (3) forming the walls of the reaction chamber is designed as a flexible film, preferably a composite film.

    Abstract: A cooling apparatus includes a brine circuit through which brine flows, a pump disposed on the brine circuit, and a heat exchanger unit including a heat absorbing member and a heat radiating member. The heat absorbing member is in communication with the brine circuit. The heat absorbing member is capable of conducting heat generated from a cooling object to the brine for cooling the cooling object. The heat radiating member is in communication with the brine circuit and capable of receiving the heat from the brine. The brine circuit is configured such that the brine passes through the heat exchanger unit at a pressure equal to or lower than an atmospheric pressure.

  • Patent number: 7284594
    Abstract: A radiator 9 for electric parts use, which cools an inverter and others relating to the control of an electric motor, and a condenser 12 for condensing refrigerant are arranged in parallel with each other with respect to the direction of an air flow on an upstream side of the air flow of a radiator 8 for engine use. Due to the above arrangement, as the air temperatures at the inlets of the radiator 8 for electric parts use and the condenser 12 are low, a temperature difference between air and cooling water and a temperature difference between air and refrigerant are increased, and it becomes possible to enhance the performance of the radiator 8 for electric parts use and the condenser 12.
