Abstract: A battery pack includes a plurality of cell assemblies each of which include one or more prismatic batteries. A frame has legs sized and configured to be positioned around the prismatic batteries. At least one leg includes a rear face, curved outer edge and a side face. A thermal transfer sheet is made from a sheet of a compressed mass of exfoliated graphite particles. Each thermal transfer sheet is positioned to contact the major surface of the at least one prismatic battery and is bent over the curved outer edge. At least a portion of each thermal transfer sheet is secured between a heat sink and the side face.

Abstract: A heat spreader for high volume manufacturing of a heat source, having a heat spreader composition which comprises a heat spreader material, an adhesive thereon, and a release material. The adhesive and release material are selected to prevent delamination of the heat spreader material when the release material is removed during the high volume manufacturing process of heat sources.

Abstract: An electronic device having a heat source disposed in direct alignment with a battery for the device and a thermal management system in thermal contact with the heat source. The thermal management system may extend from at least a first surface of the battery to a second surface of the battery. The second surface of the battery may be adjacent a heat dissipation element. The thermal management system may further be in thermal contact with the heat dissipation element. Further a portion of the thermal management system extends along the first and second surfaces of the battery and has a sufficiently high anisotropic ratio to avoid the transfer of heat to the battery to the extent to inhibit the functioning of the battery.

Abstract: A light bulb (10) including an outer housing (12) shaped like a standard Edison light bulb. The interior of the bulb includes a circuit board (24) and one or more LEDs (26). A heat sink (30) is provided inside the bulb housing that draws thermal energy away from the LEDs using graphite based materials.
Abstract: A heat exchanger assembly includes a fluid transfer layer and a first external layer. The fluid transfer layer is made from an elastomeric material and the first external layer includes flexible graphite. The fluid transfer layer includes at least one channel and is configured to form a passage for receiving a thermal transfer fluid between the channel and a portion of the first external layer.
