THERMAL MANAGEMENT SYSTEM WITH VARIABLE-VOLUME MATERIAL

摘要

Thermal management system intended to be fitted between a hot source (SC) and a cold source (SF), comprising a first (2) and a second (4) conductor of heat, a thermal switch (6) able to connect thermally, or not connect, the first (2) and second (4) conductors of heat, said thermal switch (6) comprising at least one phase-change material (12), said material (12) being able to connect the first (2) and second (4) conductor by varying its volume, said thermal switch (6) comprising control means intended to supply heat energy to the phase-change material (12) in order to change the connection status. Connection is made when the hot source (SC) exceeds a critical temperature, connection allowing a heat flux to be established between the hot source (SC) and the cold source (SF).
