Abstract
The invention discloses an all-glass heat pipe vacuum collector tube provided with a condenser lens. A light incidence surface of a glass tube on an evaporation section is a transparent glass tube, and a heat absorption membrane which is more than or equal to a half of the tube surface is compounded longitudinally on a backlight surface of the glass tube on the evaporation section; and one end of the glass tube on the evaporation section is sealed. The glass tube on the condensation section and the glass tube on the evaporation section are in sealed connection through welding. The glass tube on the condensation section is provided with a filling nozzle for a phase change heat transfer medium. The glass tube on the evaporation section is sleeved in an external glass shield tube, and a condenser lens is arranged on the external glass shield tube and is a Fresnel lens or a convex lens. An opening of the external glass shield tube is in annular welding with the glass of the glass tube on the evaporation section. An internal glass tube corresponding to the external glass shield tube is the evaporation section, and a tube outside the external glass shield tube is the condensation section. The phase change heat transfer medium is filled in the all-glass heat pipe through the filling nozzle, and the filling nozzle is sealed after vacuum treatment. The phase change heat transfer medium is directly heated after the heat is absorbed through the heat absorption membrane layer, so the heat efficiency is improved, and the all-glass heat pipe vacuum collector tube has the function of heat accumulation.
