ABSTRACT:
A heat dissipation device comprises a radiator comprising a collar, a core received in the collar and a helical heat pipe embedded in a circumferential face of the core. The collar has a receiving hole and a plurality of fins extending radially and outwardly from an outer face of the collar. The core together with the heat pipe is received in the receiving hole of the radiator. The core has a flat bottom face and a top face opposite to the bottom face. The heat pipe is located between the radiator and the core and thermally contacts the collar of the radiator and the core. The heat pipe extends from the bottom face of the core to the top face of the core, and has a flattened bottom face coplanar with the bottom face of the core for contacting with an electronic device.
