A lithium ion battery pack includes a plurality of prismatic lithium polymer cells and one or more graphite heat spreaders. Each spreader has at least two major surfaces and is made of one of a sheet of a compressed mass of exfoliated graphite particles, a graphitized polyimide sheet, or combinations thereof.

Thermal solution for prismatic lithium ion battery pack

A display device includes a heat sink and an LCD panel having peripheral edges. The LCD panel includes a non-activated area extending inwardly a predetermined distance from the peripheral edges. A thermal link is provided, made from an anisotropic graphite material, and is in thermal contact with the heat sink and with at least a portion of the non-activated area of said LCD panel.

Display device with thermal link

A handheld device (), including a projector module () which includes a light source having a laser or at least one light emitting diode; a thermal management system which includes a heat collector () 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 () 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.

Thermal management for handheld projectors

A method for preparing resin-impregnated graphite articles, including providing a sheet of compressed particles of exfoliated graphite having two major surfaces; impregnating the sheet with a first resin system to form a resin-impregnated sheet; surface treating the resin-impregnated sheet to form at least one structure on at least one of the major surfaces of the sheet to form a surface treated sheet; and treating the sheet with a second resin system.

Dimensionally stable, leak-free graphite substrate

Housing for a recessed light

A method for reducing temperature-caused degradation of the performance of a digital reader comprising pixels, the method including positioning at least one sheet of compressed particles of exfoliated graphite adjacent to a plurality of the pixels of the digital reader.

Method for reducing temperature-caused degradation in the performance of a digital reader

A circuit assembly including a substrate which has a dielectric layer, a heat spreader layer located at a first surface of the substrate, a heat generating component located at a second surface of the substrate, and a thermal pathway in thermal connection between the heat spreader layer and the heat generating component.

Heat spreading circuit assembly

A material comprising aerogel particles and a polytetrafluoroethylene (PTFE) binder is formed having a thermal conductivity of less than or equal to 25 mW/m K at atmospheric conditions. The material is moldable or formable, having little or no shedding of filler particles, and may be formed into structures such as tapes or composites, for example, by bonding the material between two outer layers. Advantageously, composites may be flexed, stretched, or bent without significant dusting or loss of insulating properties.

Aerogel/PTFE composite insulating material

A compound heat sink for the removal of thermal energy useful for, inter alia, electronic devices or other components. The compound heat sink includes a die cast base element; an extruded dissipation element having a thermal conductivity of at least about 150 W/m-K; and a thermal connection material positioned between and in thermal contact with each of the base element and the dissipation element, wherein the thermal connection material having an in-plane thermal conductivity greater than the thermal conductivity of the dissipation element.

Compound heat sink

A graphite heat spreader is provided for use with a flash LED light source for a camera of a handheld device such as a cell phone. Dramatically reduced operating temperatures are provided at substantially increased power levels thus providing both improved lighting and improved operating life of the electronic components.

Cycling LED heat spreader

A light emitting diode comprising a body and a thermal via integral therewith and which extends from the body.

LED with integral via

A thermal management device for the removal of thermal energy useful for, inter alia, electronic devices or other components.
