ABSTRACT:
A thermal management system (300) includes a first heat transfer body (330) for providing a opposing heat flux to at least one localized region of elevated heat flux residing in adjacency to a region of lesser flux, such as on a surface (315a) of a circuit die (315) due to a integrated circuit hot-spot (310). A contact (320, 321 962a, 962b, 970a, 970bor950) defines a thermal conduction path for the opposing flux. A second heat transfer body (350) is in a heat transport relationship with the first heat transfer boy (330) and a second heat transport relationship with the region of lesser heat flux. In such arrangement, each region of heat flux is provided a thermal solution commensurate with the level of heat flux in the region. For example, the opposing heat flux of an active first heat transfer body (330), such as a thermoelectric cooler, may be provided at the hot-spot (310), while at the same time the lesser heat flux is absorbed by a passive second heat transfer body (350), such as a heat spreader.
