A　new　cooling　concept　for　high　power　LED　by　combining　the　heat　release　of　high　power　LED　with　two-phase　heat　transfer　heat　pipes　was　proposed,　and　in　this　study　a　new　type　of　heat　pipe　with　specific　fins　structure　was　developed.　Through　experimental　results,　we　found　the　new　heat　pipe　heat　exchanger　has　the　features　of　high　efficiency　of　heat　dissipation　and　compact　construction　which　meets　the　demand　of　heat　dissipation　for　high　power　LED.　We　also　found　the　heat　dissipation　performance　of　the　HP　heat　exchanger　changed　with　the　work　angle.
