The invention relates to a structure comprising at least one thermal management element comprising: a composite body () containing at least one phase change material (PCM) in a structuring rigid matrix, such that the composite body is self-supporting regardless of the phase of the phase change material contained, the composite body () being shaped to locally externally present at least one elongated depression () which by itself defines a channel wall () suitable for the circulation of a fluid.

Thermal management structure with fluid channels

The invention relates to a structure comprising at least one thermal management element comprising : a composite body () containing at least one phase change material (PCM) in a structuring rigid matrix, so that the composite body is self-supporting regardless of the phase of the phase change material contained, and/or a plastic or metal bag, gas-tight and under partial internal vacuum, having a shape maintained by the internal vacuum, the composite body () and/or the bag being shaped so as locally to present externally at least one elongated cavity () which by itself defines a channel wall () suitable for the circulation of a fluid.

Thermal management structure with integrated channels

The invention relates to an assembly comprising a plurality of cells () of an electric vehicle battery () between which a first passage () may receive fluid via a first supply (). On another side () of the cells, a second passage () may receive fluid via a second supply (). Around the cells, a peripheral passage () may also receive fluid via another supply (). The second passage () and/or the peripheral passage () is interposed between a thermal insulator () and two successive cells. Flow control means () provide a thermal exchange fluid flow through at least one of the first, second and additional fluid supplies during a first time period and through at least two of the first, second and additional fluid supplies during a second time period.
