The heat collecting and accumulating integrated pipe 1000 includes a water storage pipe 1100 and a heat collecting plate 1200.
The water storage tube 1100 includes an end cap 1110 and a straight tube 1120. As shown in fig. 4, two end caps 1110 are arranged side by side and located at the left and right ends of the straight tube 1120 respectively, a plurality of straight tubes 1120 arranged side by side are arranged between the two end caps 1110, and in this embodiment, six straight tubes 1120 are arranged between the two end caps 1110, as shown in fig. 2. The end cap 1110 has a slot 1111 at a side near the straight tube 1120, and the slot 1111 is used for matching with the straight tube 1120. The end cap 1110 is connected to the straight tube 1120 by fasteners 1130, and the fasteners 1130 are bolts.
When assembling the water storage tube 1100, the right end of the straight tube 1120 is inserted into the slot 1111 of one end cap 1110, the left end of the straight tube 1120 is inserted into the slot 1111 of the other end cap 1110, and the end cap 1110 is fastened to the straight tube 1120 by bolts, thereby completing the assembly of the water storage tube 1100.
Through the above process of assembling the water storage tube 1100: the structure of the cartridge 1100 is easy to assemble, so that the assembly efficiency of the cartridge 1100 is high. In addition, the slot 1111 formed on the end cover 1110 can prevent the straight pipe 1120 from sliding on the end cover 1110, so that the straight pipe 1120 and the end cover 1110 are firmly assembled together, the structural firmness of the water storage pipe 1100 is improved, and the operation safety is improved.
The end cap 1110 on the left side of the straight tube 1120 is provided with a cold water inlet 1112 and a hot water outlet 1113. The end covers 1110 positioned at the left side and the right side of the straight pipe 1120 are provided with connecting pipes 1114, the connecting pipes 1114 are used for connecting two adjacent straight pipes 1120 in series, so that the two adjacent straight pipes 1120 are communicated through the connecting pipes 1114, and all the straight pipes 1120 positioned between the two end covers 1110 form a pipeline for the water flow to flow in a snake shape.
The heat collecting plates 1200 are welded on the same side of all the straight pipes 1120, the surface of each heat collecting plate 1200 is coated with a solar selective absorption coating, and the heat collecting plates 1200 and the outer pipe wall of the straight pipes 1120 surround to form a heat preservation cavity 1210.
When the heat collecting and accumulating integrated pipe 1000 is assembled, the heat collecting plate 1200 is directly welded to the straight pipe 1120 in the assembled water storage pipe 1100, and the assembling process is simple, convenient and quick, so that the assembling efficiency of the heat collecting and accumulating integrated pipe 1000 is improved.
The back plate 2000 is installed at one side of the bezel 3000. The heat collecting and accumulating integrated pipe 1000 is installed in the frame 3000, and the heat collecting plate 1200 in the heat collecting and accumulating integrated pipe 1000 is disposed away from the back plate 2000. The back plate 2000 is provided with a cold water avoiding hole for fitting with the cold water inlet 1112 and a hot water avoiding hole for fitting with the hot water avoiding hole 1113. When the heat collecting and accumulating integrated pipe 1000 is installed in the frame 3000, the cold water inlet 1112 needs to be inserted into the cold water avoiding hole on the back plate 2000, and the hot water outlet 1113 needs to be inserted into the hot water avoiding hole on the back plate 2000.
And insulating layers 4000 are arranged between the frame 3000 and the water storage pipe 1100 and between the back plate 2000 and the water storage pipe 1100. The heat insulation layer 4000 arranged between the frame 3000 and the water storage pipe 1100 is fixed on the inner wall of the frame 3000 through screws; the insulating layer 4000 disposed between the back plate 2000 and the water storage pipe 1100 is fixed to the back plate 2000 by screws. The insulating layer 4000 is used to reduce heat loss of the heat collecting and accumulating integrated pipe 1000.
The insulating layer 4000 is preferably a vacuum insulation panel, which is an existing product in the market, and has excellent insulating effect and thin and light weight. Because the vacuum insulation panel is an existing product in the market at present, the vacuum insulation panel is convenient for workers to take materials, thereby being convenient for assembly and improving the assembly efficiency. Since the vacuum insulation panel has an excellent insulation effect, after the vacuum insulation panel serving as the insulation layer 4000 is assembled, the heat loss of the heat accumulation integrated pipe 1000 can be reduced. Because the vacuum insulation panel has the characteristics of thin thickness and light weight, after the vacuum insulation panel serving as the heat insulation layer 4000 is assembled, the volume and the weight of the heat accumulation integrated solar water heater can be reduced, so that the transportation, the storage and the installation are facilitated.
The transparent light guide plate 5000 is installed at one side of the frame 3000 away from the back plate 2000 such that the heat collecting plate 1200 in the heat collecting and accumulating integrated pipe 1000 is disposed close to the transparent light guide plate 5000. The transparent light guide plate 5000 is used to seal an inner cavity surrounded by the frame 3000 and the back plate 2000, and also used to allow sunlight to irradiate the heat collecting plate 1200 through the transparent light guide plate 5000 for heat collection.
The transparent light guide plate 5000 is preferably a force-resistant plate. The endurance plate is a product on the market at present, and the excellent light transmission and energy saving performance of the endurance plate are also known to the public. The light transmittance of the endurance plate is comparable to that of glass; the energy saving of the endurance plate is realized by low heat conductivity and reduced heat loss. Because the endurance plate is an existing product in the market, the material taking of workers is facilitated, the assembly is facilitated, and the assembly efficiency is improved. Since the strength plate has excellent light transmittance and energy saving, when the strength plate is assembled as the transparent light guide plate 5000, the dissipation of heat of the heat collecting and accumulating integrated tube 1000 located in the frame 3000 can be reduced, and the heat collecting effect of the solar selective absorption coating of the heat collecting plate 1200 on the heat collecting and accumulating integrated tube 1000 can be improved.
The working principle of the heat-collecting and heat-storing integrated solar water heater of the embodiment is as follows: sunlight irradiates onto the heat collecting plate 1200 in the heat collecting and accumulating integrated tube 1000 through the transparent light guide plate 5000, the solar selective absorption coating on the surface of the heat collecting plate 1200 converts light energy into heat energy to be transmitted to the tube wall of the straight tube 1120 in the water storage tube 1100 in the heat collecting and accumulating integrated tube 1000, and cold water stored in the water storage tube 1100 absorbs the heat on the tube wall of the straight tube 1120 and then is heated to hot water. When hot water is needed, cold water is added into the water storage pipe 1100 in the heat collecting and accumulating integrated pipe 1000 through the cold water inlet 1112, the cold water pushes against the hot water in the water storage pipe 1100, and the hot water flows out from the hot water outlet 1113 to be used by a user.
As can be seen from the above description of the heat collecting and accumulating integrated solar water heater of the present embodiment:
