Abstract:
1. A projector comprising: a housing; a light source located in the housing; a heat pipe located in the housing, the heat pipe having phase changeable working fluid sealed therein, and having an evaporating section thermally contacting the light source for absorbing heat from the light source, and a condensing section extending remote from the evaporating section; a fin set positioned onto the condensing section of the heat pipe and thermally connecting therewith; and a fixing member, wherein the evaporating section of the heat pipe is sandwiched between the fixing member and the light source; wherein heat generated by the light source is absorbed by the evaporating section of the heat pipe and transferred to the fin set via the condensing section of the heat pipe to be dissipated; wherein the evaporating section of the heat pipe has a first flat face thermally contacting the light source; and wherein the fixing member comprises a plate and two flanges extending from the plate, and the evaporating section of the heat pipe has a second flat face contacting the plate.
