Abstract
A device for use in a circuit for cooling and/or heating a motor vehicle battery, including: an outer casing of a composition including: from 20% to 65% by weight of reinforcing fibers, which do not have thermal conduction properties, the balance being a matrix including at least one polyamide and an inner casing positioned facing the battery and intended to be in contact with a coolant of a composition including: from 5% to 65% by weight of reinforcing fibers, from 10% to 20% by weight of at least one thermally conductive component, when the reinforcing fibers used are not thermally conductive, at least one fire retardant, and the balance being a matrix including at least one polyamide chosen from semiaromatic polyamides and polyamides, a heat transfer fluid inlet; and a heat transfer fluid outlet, the device delimiting a battery cooling and/or heating volume.
