Abstract (en)

[origin: WO2010030307A1] To provide a heat radiator that is useful for an LED package, high-load semiconductor, high-load capacitor or an integrated circuit board composed of a combination thereof that assumes a short lifetime and falls at high temperatures. To constitute a heat radiator that is low in cost, superior in mechanical strength, and, furthermore, superior in heat radiating effect, by combining a graphite -metal complex that is good in heat diffusivity and an aluminum heat sink that is large in heat radiating surface area.
