1. , a kind of glass evacuated ring cavity solar conversion heat pipe, comprise the glass shell, metallic support bullet card, heat-conducting work medium, the transducing lamina membranacea, formations such as getter, it is characterized in that:

  • glass evacuated ring cavity solar conversion heat pipe is non-isometrical by three, one end end socket, by the concentric locating of metallic support bullet card, full-closed ring glass welding forming, wherein, in, little non-isometrical two channel closures are with the end suit, by metallic support bullet card, be positioned glass tube end socket end with one heart mutually, in, the concentric glass welding of little non-isometrical two tube openings, forming glass end socket one end is free end, and ring glass seal welding end is the heat-conducting work medium ring cavity glass tube of the annular heat-conducting work medium cavity volume of having of stiff end, and heat-conducting work medium fills in heat-conducting work medium ring cavity pipe;

    Wherein, the free end glass tube end socket of little caliber is non-pressure-bearing surface, and this glass end socket can be the at first explosion of other position of the heat-conducting work medium ring cavity glass tube of transducing lamina membranacea prior to outer surface daylighting position under certain pressure, makes the glass explosion relief valve;

    The corresponding heavy caliber outer layer glass tube of the cavity volume openend of heat-conducting work medium ring cavity glass tube seal head end, be loaded in the outer glass pipe by metallic support bullet card concentric locking collar, the glass tube outer wall ring packing glass welding of outer glass pipe opening and heat-conducting work medium ring cavity glass tube, formation is sleeved on together, seal into three layers of glass tube annular housing that is nested, be followed successively by the big caliber housing of glass, the vacuum ring cavity, caliber housing in the glass, the heat-conducting work medium ring cavity, glass tubule footpath housing, the structure of vacuum tube chamber, wherein, big caliber outer glass pipe communicates with heat-conducting work medium ring cavity glass tube vacuum tube chamber with vacuum ring cavity between the heat-conducting work medium ring cavity glass tube, heat-conducting work medium ring cavity glass tube outside the glass capsulation annular welds contact line of demarcation is the heat release section of glass evacuated ring cavity solar conversion heat pipe, vacuum ring cavity glass tube within the glass capsulation annular welds contact line of demarcation is the thermal-arrest section of glass evacuated ring cavity solar conversion heat pipe, the outer tube wall side to light of thermal-arrest section heat-conducting work medium ring cavity pipe is the transducing lamina membranacea, the big caliber outer glass pipe sealing-in termination upper glass of glass evacuated ring cavity solar conversion heat pipe is welded with tailpipe, and the middle caliber outer glass pipe sealing-in termination upper glass of heat-conducting work medium ring cavity glass tube is welded with exhaust, fill the tail pipe of heat-conducting work medium;

    Between the heat release section of heat-conducting work medium ring cavity glass tube and the thermal-arrest section for there to be the installation of heat insulating function to be connected sealing surface, heat-conducting work medium or be the aqueous solution, or be fluid organic material, or be the phase transformation organic matter, heat-conducting work medium has low boiling under the vacuum, low-pressure under the high temperature, heat conductivility is good, the characteristics that physicochemical property is stable.
