Configurational tree-shaped heat pipe radiator

Abstract

The invention discloses a configurational tree-shaped heat pipe radiator. The radiator consists of a high-thermal conductivity base plate, liquid-absorption cores, a radiating fin and working media, wherein narrow cavities are formed inside the base plate; the radiating fin is connected with the narrow cavities; communicated cavities are formed inside the radiating fin; the liquid-absorption cores are filled in the narrow cavities; the working media are filled in the narrow cavities and the communicated cavities; the radiating fin has a configurational tree-shaped structure and consists of a main communicated channel and at least two forked connection fins; the forked connection fins are arranged at the periphery of the main communicated channel circularly; and the communicated cavities inside the forked connection fins are communicated with the main communicated channel. The heat pipe radiator can quickly remove the heat which is generated by a plurality of (a single) local high-temperature heat flow heat source points (point) through phase change of the working media, so that local hot points are effectively eliminated, temperature of a heating surface of the heat pipe radiator is reduced, and safe, stable and efficient operation of electronic equipment is further guaranteed.
