The end of the vacuum tube 2 also includes a connecting pipe opening 21 extending from at least one end of the tube body 21. The shape of the connecting pipe opening 21 is a constriction, and the pipe opening 22 at the other end is a matching pipe opening that matches the constriction-shaped connecting pipe opening. Figure 1The vacuum heat collecting tubes 1 and 2 have the same structure, for example, the vacuum heat collecting tube 1 includes a tube body 11, the tube body 11 includes an inner tube 120, an outer tube 100, and a vacuum interlayer 110 located between the inner tube 120 and the outer tube 100, the left end is a connecting tube opening 13 and the right end is a matching tube opening 12. In another embodiment, the structures of the vacuum heat collecting tubes 1 and 2 are different, for example, both ends of the vacuum heat collecting tube 1 are straight tube openings.

[0043] like Figure 1 As shown, the constricted connecting pipe opening 21 is inserted into the matching pipe opening 22, and a sealing element 3 is provided between the connecting pipe opening 21 and the matching pipe opening 22. The sealing element 3 can be fixed on the outer periphery of the connecting pipe opening 21, or fixed on the inner periphery of the matching pipe opening 22. The sealing element 3 can be made of polytetrafluoroethylene. The connecting pipe opening 21 is made of single-layer glass. On the one hand, the constricted connecting pipe opening 21 will not substantially affect the diameter of the vacuum collector tube, and the effect of the constricted connecting pipe opening 21 on the diameter is about 3-5 mm. On the other hand, there will be no thickness that affects the visual effect at the connection of the two vacuum collector tubes.

[0044] and Figure 1 The embodiment shown is different in that Figure 2 In the embodiment shown, the connecting pipe opening 21 includes an inner pipe extension portion 220A, an outer pipe extension portion 200A and an interlayer extension portion 210A respectively extending from the inner pipe 220, the outer pipe 200 and the vacuum interlayer 210. The connecting pipe opening 21 is also in a constricted shape. Similarly, the constricted connecting pipe opening 21 will not substantially affect the diameter of the vacuum heat collecting pipe on the one hand, and will not have a thickness that affects the visual effect at the connection of the two vacuum heat collecting pipes on the other hand.

[0045] Figure 3 The third embodiment between the vacuum heat collecting tubes 1 and 2 is shown. The vacuum heat collecting tube 2 includes a tube body 21. The tube body 21 includes an inner tube 220, an outer tube 200 and a vacuum interlayer 210 located between the inner tube 220 and the outer tube 200. The outer tube 200 can transmit sunlight. The outer surface or the interior of the inner tube 220 is arranged with solar heat collecting materials (not shown in the figure) that absorb solar radiation. The end of the vacuum heat collecting tube 2 also includes a connecting pipe opening 21 extending from at least one end of the tube body 21. The connecting pipe opening 21 is in the shape of an expanded opening. The pipe opening 22 at the other end is a matching pipe opening that matches the shrinking connecting pipe opening, which is a straight pipe opening. Figure 3 The vacuum heat collecting tubes 1 and 2 have the same structure, for example, the vacuum heat collecting tube 1 includes a tube body 11, the tube body 11 includes an inner tube 120, an outer tube 100, and a vacuum interlayer 110 located between the inner tube 120 and the outer tube 100, the left end of the vacuum heat collecting tube 1 is a flared connecting tube opening 13 and the right end is a matching tube opening 12. In another embodiment, the structures of the vacuum heat collecting tubes 1 and 2 are different, for example, both ends of the vacuum heat collecting tube 1 are straight tube openings.

[0046] like Figure 3 As shown, the flared connecting pipe opening 21 is sleeved on the outer peripheral side of the matching pipe opening 22, and a sealing element 3 is provided between the connecting pipe opening 21 and the matching pipe opening 22. The sealing element 3 can be fixed on the inner periphery of the connecting pipe opening 21, or fixed on the outer peripheral side of the matching pipe opening 22. The sealing element 3 can be made of polytetrafluoroethylene. The connecting pipe opening 21 is made of single-layer glass. On the one hand, the flared connecting pipe opening 21 will not substantially affect the diameter of the vacuum collector tube, and on the other hand, there will be no thickness that affects the visual effect at the connection of the two vacuum collector tubes. The connection thickness affected by the flaring is about 3 mm.

[0047] and Figure 3 The embodiment shown is different in that Figure 4 In the embodiment shown, the connecting pipe opening 21 includes an inner pipe extension portion 220A, an outer pipe extension portion 200A and an interlayer extension portion 210A respectively extending from the inner pipe extension portion 220, the outer pipe 200 and the vacuum interlayer 210. The connecting pipe opening 21 is also in a flared shape. Similarly, the flared connecting pipe opening 21 will not substantially affect the diameter of the vacuum heat collecting pipe on the one hand, and will not have a thickness that affects the visual effect at the connection of the two vacuum heat collecting pipes on the other hand.

[0048] Figure 5 An embodiment of a solar building module is shown, which can be used as a sunshade to build a sunshade, a sunshade roof, etc. The solar building module includes a plurality of vacuum heat collecting tubes 4, which have Figures 1 to 4 For any vacuum heat collecting tube structure shown in, for example, the tube openings of all vacuum heat collecting tubes on one side of the building module are constricted or expanded connecting tube openings, or part of them are matching tube openings and part of them are connecting tube openings, that is, part of them are constricted or expanded connecting tube openings and part of them are matching tube openings that match these constricted or expanded connecting tube openings, and the tube openings on the other side of the building module are the same. Figure 5 The expanded or contracted structure is not visually displayed because its size is relatively small relative to the overall length. In this building module, the two ends of the vacuum heat collecting tube 4 are connected by a module connection device 5, which is, for example, a plurality of clamps connected together, and a rubber gasket is provided on the inner wall of the clamp. Fig.13 As shown, two solar building modules are butted together, and the connection structure at the butt joint is as follows Figures 1 to 4 In any connection mode, the sealing elements can be connected together to form a sealing joint 3' to simplify the installation steps. In addition, as mentioned above, the sealing element can be pre-fixed on the butted connection pipe or matching pipe. In another embodiment, rainproof sealing materials are arranged between the plurality of vacuum collector pipes 4, so that they can also be used as a rain shelter.

[0049] Figure 6 The second embodiment of the solar building module is shown, the overall roof tile structure can be used for laying the roof, Figure 6 The two solar building modules are butt-jointed and assembled together. The solar building module comprises a plurality of vacuum heat collecting tubes 1 or 2 arranged in parallel. The vacuum heat collecting tubes are arranged as follows. Figures 1 to 4 Any of the heat collecting tube structures shown in Figure 6 and Fig.11 As shown, these vacuum heat collecting tubes 1 or 2 are laid on a base layer 8, which is made of waterproof building materials and is fixedly connected to the vacuum heat collecting tubes 1 or 2 in a detachable or non-detachable manner. Figure 7 ,and Figure 8 , Fig. 9 , Fig.10 As shown, the pipe opening at one end of the building module is a constricted connection pipe opening, which is plugged into the pipe opening, i.e., the matching pipe opening, of another building module. A sealing element is fixedly sleeved on the constricted connection pipe opening. Figure 7 and Figure 8 In addition to the embodiment shown, the docking structure of the two building modules can be Figures 1 to 4 Any of the connection structures shown in the figure. The solar building module with roof tile structure can directly replace the traditional roof tiles, that is, the solar heat collection module and the building module are integrated into a whole. As mentioned above, since the connection thickness of the heat collection pipe connection will not be significantly increased visually, the roof paved with such solar building modules and the driven roof tiles will not have any adverse effect on the appearance.

[0050] like Fig.14 As shown, Figures 6 to 10 The solar building modules shown in the figure are arranged obliquely on the roof, forming a building sunshade structure or a roof structure 6 on the south wall.

[0051] and Figure 5 The solar building modules shown are arranged vertically on the east wall or the west wall to form another type of building sunshade structure 7.

[0052] exist Figure 6 In the illustrated embodiment, some specific designs can also be considered, for example, in each building module, the vacuum heat collecting tubes are kept at a distance of more than 2 mm. For another example, an annular protective sleeve is provided at the pipe mouth connection. For another example, roofing materials such as asphalt are arranged on the back of the vacuum heat collecting tube to position the vacuum heat collecting tube and seal the gap between the vacuum heat collecting tubes. The tile surface inclined along the axis adopts a connection sequence of large on top and small on the bottom at the aforementioned pipe mouth connection, that is, the pipe mouth diameter of the building module located on the upper side of the upper side is larger than the pipe mouth diameter of the building module located on the lower side, which can effectively prevent rainwater from gathering at the connection.

[0053] Similarly, in Figure 5In the embodiment shown, some specific structural designs may also be considered, for example, when Figure 5 When the building modules shown are assembled into a south wall shading structure or a vertical shading structure for the east and west walls, a gap is retained between the collector tubes, the gap is, for example, 2 mm, and the collector tubes are connected and fixed by the aforementioned clamping device 5. The solar building modules are installed on the wall support structure and plug-connected to each other. A decorative and auxiliary supporting annular jacket can be arranged at the plug-in connection.

[0054] Fig.12 The third embodiment of the solar building module is shown, and its installation method is a wall-mounted connection method. The solar building module includes a plurality of parallel heat collecting tubes 4, which are connected together by a module connection device 8. The module connection device 8 includes a horizontally extending wall-mounted plate 81 and a vertically extending support plate 82. The support plate 82 is connected to the wall-mounted plate 81. A plurality of mounting holes 83 are arranged on the support ring plate 82. The aperture of the mounting hole 83 is smaller than the outer diameter of the tube body of the heat collecting tube 4, but larger than the outer diameter of the constricted connection pipe mouth. In this way, the support plate can play a supporting role and facilitate the insertion of the heat collecting tube. The wall-mounted plate 81 is installed on a vertical building, such as a vertical wall. The weight of the heat collecting tube 4 is transferred to the support plate 82, and the support plate 82 then transfers the overall weight to the wall-mounted plate 81, which is installed on the vertical building.
