Title: HEAT EXCHANGER WITH A FLEXIBLE WALL FOR THE HEAT MANAGEMENT OF AN ELECTRIC BATTERY
Abstract:
The invention relates to a heat exchanger (10) comprising a channel (14) for the circulation of a first heat-transfer fluid (16) and an enclosure (12) containing the channel (14). The enclosure (12) comprises a flexible wall (24) forming a heat conductor, provided with an outer surface (28) designed to come into contact with a body to be thermoregulated (36), for example a battery or a battery module. The enclosure (12) contains a second heat-transfer fluid (18), the channel (14) being housed in the enclosure (12) so as to allow the passage of the second heat-transfer fluid (18) between an inner surface (26) of the flexible wall (24) forming a heat conductor and the channel (14). The flexible wall (24) forming a heat conductor allows the second heat-transfer fluid (18) to move freely witin the enclosure (12) and to locally deform the flexible wall (24) forming a heat conductor in such a way as to maximise the contact of the flexible wall (24) forming a heat conductor with the body to be thermoregulated (36).
