Abstract: An electric power module for powering electric equipment includes: an enclosure having interconnected walls and defining an inner volume, a wall of the interconnected walls being in heat exchange relationship with an environment; a battery located within the inner volume; and a heat-conducting plate in heat exchange relationship with the battery. The heat-conducting plate has a bridge section movable between first and second positions, the bridge section being spaced apart from the wall in the first position to limit heat transfer from the battery to the environment, and the bridge section being in contact with the wall in the second position to transfer heat from the battery to the environment via the bridge section. An actuator is engaged with to the bridge section of the heat-conducting plate, the actuator being operable to move the bridge section of the heat-conducting plate between the first and second positions.

Abstract: A polymer-based heat transfer device comprising a polymer-based housing having housing walls defining a working fluid chamber, a porous structure extending in the working fluid chamber from at least one of the two opposed ones of the housing walls, and a plurality of housing wall spacers, such as support posts, extending between the two housing walls to maintain the two housing walls in a spaced-apart configuration with the working fluid chamber extending in between is provided. Also described is a polymer-based heat transfer device comprising a polymer-based housing having housing walls defining a working fluid chamber and a porous structure extending in the working fluid chamber from at least one of the two opposed ones of the housing walls, and heat-conductive metal or ceramic-based foam contacting at least one of the housing walls. A process for manufacturing the polymer-based heat transfer device is provided.
