THERMAL MANAGEMENT STRUCTURE WITH INTEGRATED 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.
