  • Patent number: 11209218
    Abstract: The present invention relates to a heat exchanger, an energy recycling system, a fluid distribution manifold and a baffle. The heat exchanger comprising: a first fluid tube through which a first fluid of a first temperature flows; a second fluid tube through which a second fluid of a second temperature flows; a baffle located in at least one of said tubes for moderating flow of at least one fluid passing therethrough; wherein the heat exchanger is configured for communicating thermal energy between the first fluid and the second fluid.

  • Patent number: 10254007
    Abstract: An energy transmission system for exchanging thermal energy of a medium in a sealed loop with a compressor, a control valve, and two heat exchangers between the compressor and the control valve such that a medium flowing between the compressor and the control valve absorbs thermal energy from one heat exchanger and releases thermal energy through the other heat exchanger. The compressor (22) changes the pressure of the medium in the loop such that the pressure through one heat exchanger is different from the pressure through the other heat exchanger, and the physical state of the medium is different between regions of the sealed loop.

  • Patent number: 9932724
    Abstract: A fluid control device includes a housing and a fluid temperature control assembly. The housing includes a first inlet, a second inlet for receiving a fluid, and a first outlet through which a fluid of a third temperature flows. The fluid temperature control assembly is in the housing, with apertures for regulating fluid communication between a mixing cavity and the first inlet of the housing, apertures communicating with the first outlet. The fluid temperature control assembly modifies properties of the apertures for regulating the amount of fluid having a first temperature relative to the amount of fluid having a second temperature with the mixing cavity, thereby maintaining the fluid discharged from the first outlet at a predetermined temperature.

  • Patent number: 7255959
    Abstract: A battery contact to engage with and to conduct electricity from a terminal of a battery where the battery contact is made from an elongate wire formed to define a) a torsional region of a substantially straight section of the wire and b) a battery terminal contact region extending substantially laterally from the torsional region at a first end of the torsional region, the battery terminal contact region including a battery terminal contact point, and c) a restraining leg of the wire extending substantially laterally from the torsional region at a second end of the torsional region, where the battery terminal contact region is resiliently rotatable relative to the restraining leg about the torsional region, but wherein the displacement of the battery terminal contact region and restraining leg are biased back to an original angular condition as a result of torsional rigidity provided by the torsional region such that in use, the battery contact is supported by a holder in a manner to hold the restraining
