Thermal control apparatus using shape memory alloy, power electronic system having the same, and shape memory alloy structure thereof

摘要

The present invention relates to a heat control device using a shape memory alloy, a power electronic system having the same, and a shape memory alloy structure thereof. A heat control device according to an embodiment of the present invention includes a heat sink disposed on one side of a heat generating electronic device module; an elastic body providing an elastic force in a direction opposite to the direction in which the heat sink is disposed with respect to the heat generating electronic device module; and a shape memory alloy, and becomes a first shape that separates direct or indirect contact of the heat generating electronic device module to the heat sink by the elastic force of the elastic body in the first state, and heats according to the shape memory action in the second state It characterized in that it includes a shape memory alloy structure having a second shape for directly or indirectly contacting the heat generating electronic device module to the sink.
