  • Patent number: 11828060
    Abstract: A method of making an insulated material comprises melting a phase change material to form liquid phase change material, combining the liquid phase change material with an insulating material, and forming a composite insulation material in response to the combining. The insulating material can be a porous material that comprises a plurality of pores, and the liquid phase change material is disposed in the plurality of pores. The phase change material can also be stored in a container and used as layer in an insulation system.
    Type: Grant

  • Patent number: 10349563
    Abstract: The invention provides a single radiator cooling system for use in hybrid electric vehicles, the system comprising a surface in thermal communication with electronics, and subcooled boiling fluid contacting the surface. The invention also provides a single radiator method for simultaneously cooling electronics and an internal combustion engine in a hybrid electric vehicle, the method comprising separating a coolant fluid into a first portion and a second portion; directing the first portion to the electronics and the second portion to the internal combustion engine for a time sufficient to maintain the temperature of the electronics at or below 175° C.; combining the first and second portion to reestablish the coolant fluid; and treating the reestablished coolant fluid to the single radiator for a time sufficient to decrease the temperature of the reestablished coolant fluid to the temperature it had before separation.
