  • Patent number: 10177070
    Abstract: A flexible graphite sheet support structure forms a thermal management arrangement for device having a heat source. The flexible graphite sheet support structure includes first and second spaced apart support members and a flexible graphite sheet secured to the spaced apart support members forming a free standing flex accommodating section that spans between them. Curve retention members having convex curved surfaces are used to keep the flex accommodating section in a bell shaped curve while preventing the flexible graphite sheet from exceeding a minimum bend radius. The thermal management arrangement formed by the flexible graphite sheet support structure enables the flexible graphite sheet to move heat from one support structure to the other while reducing the transmission of vibration between them and allowing relative movement between the spaced apart support structures.

  • Patent number: 8955983
    Abstract: A handheld device (10), including a projector module (20) which includes a light source having a laser or at least one light emitting diode; a thermal management system which includes a heat collector (30) formed of a material having a thermo-mechanical design constant of at least 10 mm-W/m*K and having a non-planar shape, the heat collector in thermal contact with the light source; a heat spreader (40) having a surface area at least 1.5 times that of the surface area of the heat collector and a thermo-mechanical design constant of at least 10 mm-W/m*K, the heat spreader positioned in thermal contact with the heat collector, wherein thermo-mechanical design constant of a material is defined by thermal conductivity of the material multiplied by its average thickness.
