The invention is applicable to the field of radiators, and provides an embedded radiator, which comprises a radiating bottom plate, an embedded groove recessed inwards from the top surface of the radiating bottom plate, and a heat absorption surface arranged on the bottom surface of the embedded groove; the
heat pipe is in a flat shape, the
heat pipe is contained in the inlaying groove, the
heat pipe comprises an
evaporation section and a condensation section which are oppositely arranged, and the
evaporation section is connected to the heat absorption surface; and the radiating fins are connected to the condensation sections of the heat pipes in a surface-mounted
welding manner. According to the embedded radiator, the heat
pipe is arranged to be flat and embedded in the embedding groove of the radiating bottom plate, and the radiating fins are welded to the heat
pipe in a surface-mounted mode, so that the embedded radiator is of an integrated structure, and solder
thermal resistance and air gaps can be effectively eliminated. The
evaporation section of the heat
pipe is directly connected to the heat absorption face of the heat dissipation bottom plate, the
heat transfer path from the
chip to the heat pipe can be shortened, the transverse
heat resistance of the heat dissipation bottom plate is reduced, rapid activation of the heat pipe is achieved, and center heat accumulation is reduced. The heat dissipation fins and the condensation section are welded in a surface-mounted mode, contact
thermal resistance between the heat dissipation fins and the condensation section can be reduced, and heat dissipation efficiency can be improved.
