▎ 摘　　要

NOVELTY - The heat sink has fins provided with predetermined length, thickness and height. The fins are composed of thermally conductive films selected from metallic film, carbon-based film, or polymer films doped with conductive particles or a combination. The metallic films are selected from films comprises aluminum, copper, stainless steel, tungsten, and/or titanium. The carbon based films are optionally selected from graphite, pyrolytic graphite. The metallic films are selected from films consists of aluminum, copper, stainless steel, tungsten, titanium, and carbon-based films are optionally selected from films comprises graphite, pyrolytic graphite, synthetic graphite, graphene, carbon nanotubes, expanded graphite, graphite composites, carbon black, diamond and polymer films are optionally selected from diamond, carbon, transition metal nitrides such as AIN, transition metal oxides such as Aluminum oxide (AlO3), ceramics, Boron nitride (BN) or SiC. USE - Heat sink for use with photovoltaic solar panel unit of photovoltaic solar panel geometry (claimed). ADVANTAGE - The design of the heat sink allows for better heat sink design and achieves a significant reduction in steady state operating temperature in a cost-effective manner. The heat sink reduces conversion efficiency and panel lifetime when panels are deployed on sites depending on local climate, thus improving the efficiency and lifetime of photovoltaic solar panels. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of heat sink for use with photovoltaic solar panel unit.
