Abstract
Thermal management systems include a heat generating device that is to be kept within a desired temperature range. A thermoregulating layer coats, or is otherwise positioned in adjacent proximity to the heat generating device. The thermoregulating layer includes a Ni—Mn based Heusler alloy that exhibits an unprecedented differential in thermal conductivity across a relevant temperature range, based on a martensitic transition from an asymmetric lattice structure to a symmetric lattice structure with increasing temperature.
