Abstract
Abstract Method and apparatus for fluid-based cooling of heat-generating devices are disclosed. A heat-generating device is mounted on a carrier. The heat-generating device is spatially displaced from the surface of the carrier, thereby forming a channel. The heat-generating device and the carrier are enclosed in an enclosure having an inlet and an outlet. A substantially electrically non-conductive cooling fluid for introduction into the enclosure and into the channel and expulsion from the enclosure and for extracting heat from and thereby cooling the heat-generating device and the carrier.
