Patent attributes
A thermal bridge includes a first plate stack, a second plate stack and a temperature responsive actuator. The first plate stack is placed in thermal communication with a first electrical component and has a plurality of first plates. The second plate stack is placed in thermal communication with a second electrical component and has a plurality of second plates interleaved with the first plates. The temperature responsive actuator is coupled to at least one of the first and second plate stacks. The temperature responsive actuator changes shape based on changes in temperature to change the relative positions of the first and second plates. The temperature responsive actuator causes the first and second plates to vary thermal resistance between the first and second electrical components based on the change in relative positions of the first and second plates.
