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　series　of　heat　pipes　with　specific　fins　structure　were　developed.　From　the　experimental　results　obtained,　it　is　found　that　the　new　heat　pipe　heat　exchanger　is　of　high　heat　dissipation　capacity　and　compact　construction　that　will　meet　the　demand　of　high　power　LED　cooling.　The　new　heat　pipe　heat　exchangers　with　different　fin　shapes　have　different　efficiency　of　heat　dissipation　and　the　new　heat　exchanger　with　outwards-radiate　fins　has　the　best　heat　dissipation　performance.　It　is　also　shown　that　the　heat　dissipation　performance　of　the　heat　pipe　heat　exchanger　changes　with　the　position　angle.　The　effects　of　the　numbers　of　heat　pipes　and　the　fin　materials　on　the　heat　dissipation　performance　of　the　whole　cooling　system　were　also　carried　out.
