  • Patent number: 10663115
    Abstract: A method for loading liquefied nitrogen (LIN) into a cryogenic storage tank initially containing liquid natural gas (LNG) and a vapor space above the LNG. First and second nitrogen gas streams are provided. The first nitrogen stream has a lower temperature than the second nitrogen gas stream. While the LNG is offloaded from the storage tank, the first nitrogen gas stream is injected into the vapor space. The storage tank is then purged by injecting the second nitrogen gas stream into the storage tank to thereby reduce a natural gas content of the vapor space to less than 5 mol %. After purging the storage tank, the storage tank is loaded with LIN.

  • Patent number: 10634397
    Abstract: Heat transfer devices and systems are provided for the rapid cooling of pulsed high-powered, high-flux devices using flash boiling. Such devices comprise at least two fluidly connected chambers and a heat exchanger in thermal communication with a heat source. A flash boiling event is actively triggered at a location close to the heat source by rapid depressurization of the chamber containing a multi-phase coolant. This boiling process allows for high heat transfer rates from the heat source into the chambers due to the latent heat of vaporization, which results in the rapid cooling of the heat source. A porous medium may also be positioned within a chamber of the device to enhance boiling nucleation and extended surface heat transfer. Methods of rapidly cooling pulsed heat sources are also provided using the devices and systems hereof.

  • Patent number: 10609841
    Abstract: Disclosed is a liquid cooling radiation system. The technical solution used by the present invention to solve the technical problem is: the liquid cooling radiation system comprises: a radiation device, comprising cooling pipes and a radiation structure device arranged on the cooling pipes; a pumping device, integrally arranged between the cooling pipes and generating power so that a coolant circulates within the cooling pipes; a heat absorption device, attached to a heating device and having a heat conduction effect with the heating device; a pipeline, used for connecting the radiation device and the heat absorption device. On the basis of existing products, the present invention utilises a solution wherein a liquid pump main body and a radiator are integrally arranged together. Thus, the radiation of a fan is used to take away heat on the radiator and heat generated by a pump power main body (i.e. a motor) itself is also taken away, thereby extending the service life of the motor.

  • Patent number: 10518608
    Abstract: A vehicle air-conditioner safety device includes a controller which, in a case in which an abnormality has occurred in a heating device that heats coolant with a heater, determines whether or not the abnormality is a restorable abnormality or a non-restorable abnormality. When the abnormality is determined to be the restorable abnormality, it is determined whether or not the restorable abnormality has been removed. Heating by the heater is prohibited when the restorable abnormality or the non-restorable abnormality has occurred. Heating by the heater is restored when the restorable abnormality has been removed after heating by the heater is prohibited due to occurrence of the restorable abnormality.

  • Patent number: 10451357
    Abstract: A method is disclosed for the operation of a mixing container of a latent heat storage unit, whereby a heat storage fluid changes between a liquid phase and a solid phase, and has a higher density than a heat transfer fluid. In this method, by virtue of the geometry of the mixing container as well as the flow path of the heat storage fluid and the heat transfer fluid through the mixing container, the solid and the liquid heat storage fluids are concentrated after being mixed with the heat transfer fluid and they are subsequently separated from the heat transfer fluid at a boundary layer and withdrawn from the heat storage fluid by a flow induced below the boundary layer in the direction of an ice reservoir via a pipeline, and subsequently, the liquid heat storage fluid is separated from the solid heat storage fluid in the ice reservoir.
