Abstract

The utility model discloses a solar energy pipe, comprising a vacuum glass pipe, in which a concentric double layer copper pipe is arranged. The concentric double layer copper pipe consists of an internal copper pipe and an external copper pipe, an end of which extends out of the vacuum glass pipe, respectively connecting with an external water inlet pipe and a water outlet pipe. The other end of the external copper pipe is sealed, and the other end of the internal copper pipe is communicated with the external copper pipe. An absorber plate, on which the external copper pipe is fastened, is positioned in the vacuum glass pipe. The utility model of solar energy pipe has the glass pipe with high transparence and relatively good solar energy absorbing performance. A heat absorption coat is arranged on the absorber plate, so that the heat energy absorption can be maximally promoted and the radiation loss of the heat energy can be reduced as far as possible. The heat loss caused by the liquid convection and heat conduction can be prevented by the unique design of double pipe. In addition, for the glass has the same expansion ratio and shrinkage ratio as the metal ware, the utility model can be effectively used in a building system for more than thirty years.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in detail.

Fig. 1 is the utility model three-dimensional structure diagram, and as shown in Figure 1, a kind of solar pipe of the utility model comprises a glass tube with vacuum 1, is provided with a concentric double-deck copper pipe 2 in the glass tube with vacuum 1, copper pipe 21 and outer copper pipe 22 in comprising.Also be provided with an absorber plate 3 in the glass tube with vacuum 1, the absorber plate surface has heat absorbing coating 31; On the absorber plate 3 one be shaped on a sleeve 32, described outer copper pipe 22 is sleeved in the described sleeve 32; Absorber plate 3 is fixed in the glass tube with vacuum 1 by a retainer 33.

Can be illustrated more clearly in structure of the present utility model in conjunction with Fig. 2, the inside contraction in end, glass tube with vacuum 1 two ends forms left neck 10 and right neck 11 respectively; The

end

211 and 221 ecks 100 from left neck 10 of one end of interior copper pipe 21 and outer copper pipe 22 stretch out outside the glass tube with vacuum 1, are used for being connected with outlet pipe with outside water inlet pipe respectively, are provided with sealing metal circle 12 between the eck 100 of double-deck copper pipe 2 and left neck; The other end 222 sealings of outer copper pipe 22, the other end end 212 of interior copper pipe is connected with outer copper pipe 22.

Be provided with one in the eck 110 of right neck 11 and dump pipe 13; The eck 110 of right neck adopts rubber stopper 14 to seal.

Adopt the solar pipe of said structure design, no matter be interior copper pipe 21 as water inlet, still outer copper pipe 22 is as delivery port, or interior copper pipe 21 is as delivery port, outer copper pipe 22 is as water inlet, and the convection current between them does not have any chance and heat energy is dispersed in the air goes.In addition, copper is as good heat conducting material, can be good at the heat energy that absorber plate 3 is collected is used to heat the liquid of flowing through, and double-deck copper pipe 2 is in the glass tube with vacuum 1, also without any heat energy being waved the possibility of loosing in air.Therefore, the thermal efficiency height of the utility model solar pipe does not almost have thermal losses.

Below in conjunction with the concrete performance that the utility model solar pipe is applied to solar energy heat collection box of introducing of accompanying drawing.

Shown in Fig. 3,4, the utility model solar energy heat collection box comprises a framework 4, is arranged with four basic utility model solar pipes in the framework 4 in parallel; Be provided with water inlet pipe 41 and outlet pipe 42 in the framework 4, water inlet pipe 41 is communicated with the interior copper pipe 21 of solar pipe, and outlet pipe 42 is communicated with the outer copper pipe 22 of solar pipe.

Practical work process is: the water (flow) direction shown in filled arrows direction among Fig. 4, copper pipe 21 in the cold water that water inlet pipe 41 enters enters, and in the copper pipe 22, flow at last in the outlet pipe 42 outside its terminal end 212 enters then.The heating process of water is conducted to outer copper pipe 22 by absorber plate 3 collecting energies and is realized, in the actual cyclic process, and the heat energy of cold water liquid conductive in the copper pipe 22 outside flowing of interior copper pipe 21 begun to accept certainly.The liquid flow direction unanimity, and the energy direction of transfer is identical, therefore can not reach maximization to the energy utilization efficiency of gathering because of the loss of convection current produce power.

As well known to the skilled person; the foregoing description only plays the exemplary role in the above-mentioned utility model protection scope; for those of ordinary skills; also have a lot of conventional distortion and other embodiment in the protection domain that the utility model limited, these distortion and embodiment will be within the protection domains that the utility model awaits the reply.
