Abstract
A heat transfer pad includes a pad inlet port for feeding a heat transfer fluid to the pad, a pad outlet port for discharging the heat transfer fluid from the pad and a bladder having an internal flowpath for the heat transfer fluid which extends from the pad inlet port to the pad outlet port. The internal flowpath is divided into a first flow channel and a second flow channel through which first and second flow streams of the heat transfer fluid, respectively, flow between the pad inlet and outlet ports. A first flow restrictor is positioned downstream in the first flow channel and a second flow restrictor is correspondingly positioned downstream in the second flow channel and the flow restrictors are configured to create substantial back pressures in the first and second flow channels, respectively.
