  • Patent number: 10851274
    Abstract: A coolant mixture including water and at least one of the compounds chosen from 1-methoxy-2-propanol and 1-ethoxy-2-propanol in the proportions of the corresponding azeotrope or in near-azeotropic proportions. Such a mixture can be used as a heat-transfer fluid in a heat-exchange device, which can be incorporated into an aircraft or spacecraft. A method for obtaining a mixture by fractional distillation is also disclosed.
    Type: Grant
    Filed: June 15, 2017
    Date of Patent: December 1, 2020
    Assignees: Safran Electrical & Power, CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE (CNRS), INSTITUT NATIONAL POLYTECHNIQUE DE TOULOUSE, ECOLE NATIONALE SUPERIEURE DE CHIMIE DE LILLE, UNIVERSITE DES SCIENCES ET TECHNOLOGIES DE LILLE

  • Patent number: 10836940
    Abstract: The present invention relates to a cooling mixture comprising a fluorinated compound and a non-fluorinated compound, wherein the fluorinated compound is a hydrofluoroether and the non-fluorinated compound includes a carbonyl function, which has a flash point no lower than 23° C. and which is characterised by having low relative volatility. The present invention likewise relates to the use of such a mixture as a coolant in a heat-exchange device.

  • Publication number: 20150042431
    Abstract: A coiled electronic power component configured to be mounted on a base, the component including an axially extending magnetic core around which a plurality of turns are wound to form a magnetic coil, and at least one bracket for mounting on the base. The mounting bracket includes at least one drain surface in thermal contact with the magnetic core and/or the plurality of turns to drain calories from the magnetic core and/or from the plurality of turns to the base during operation of the component. The mounting bracket has an equivalent thermal conductivity of greater than 400 W·m?1·K?1.
