Patent application: Cooling circuit and method on a vehicle

Ben Welter - Friday, October 12, 2018

U.S. patent application 20180291798 (applicant Hutchinson SA, Paris, France):

"A temperature management system on a vehicle cooling circuit using a heat transfer liquid, the circuit comprising a path for circulating the liquid and, arranged on the path: in series, a means for circulating the liquid along the path, an engine for moving the vehicle, whose components are to be placed in a heat exchange relationship with the liquid, and a heat exchanger having an inlet and an outlet for said liquid in order to place this liquid in a heat exchange relationship with another fluid within the exchanger, mounted on a first leg, between the inlet and the outlet of the heat exchanger, a heat store into which said liquid can enter and from which it can exit, and valves positioned so that liquid arriving from the engine flows toward the heat exchanger and/or the heat store, the heat store being a latent heat storage and thermal energy release unit containing at least one volume: enclosing elements made of phase change material (PCM) for storing and releasing the thermal energy contained in said liquid in view of a heat exchange with this liquid (9), and around which is installed a thermal barrier comprising at least one first layer containing a phase change material and which is surrounded by one second layer containing a porous thermally insulating material to thermally isolate said volume from the outside."
