Technical Field

[0001] This application relates to the field of heating equipment technology, and in particular to a glass tube solar thermal storage system. Background Technology

[0002] Solar thermal energy storage systems utilize glass heat pipes to convert solar energy into heat energy. Water absorbs heat from vacuum tubes and is heated, and then circulates in a storage tank to obtain the required heat energy. Due to its high thermal efficiency and cost-effectiveness, solar thermal energy storage systems occupy a major share of the domestic solar water heater market.

[0003] Most existing solar thermal storage systems consist of glass collector tubes, heat transfer pipes, heat transfer medium, hot water storage tank, control system, and connecting pipes.

[0004] The existing technical solutions mentioned above have the following drawbacks: the hot water storage tanks of existing solar thermal storage systems are large in size, and require the use of cranes and large transport vehicles for transportation and assembly, resulting in high costs in the transportation and assembly process. Utility Model Content

[0005] This application provides a glass tube solar thermal storage system to facilitate the transportation and assembly of hot water storage tanks and reduce the transportation and assembly costs of solar thermal storage systems.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: A glass tube solar thermal storage system includes a hot water storage tank and a collector. The hot water storage tank includes a tank body, which includes multiple panels. The multiple panels form the tank body. A lid is connected to the top of the tank body. A fixing screw is installed on the lid. Multiple fixing screws are spaced apart and pass through the panels and are connected to the bottom of the tank. The lid and the bottom are both threaded to the fixing screws. An inner tank is installed inside the tank body. A heat exchanger is installed inside the tank body. The heat exchanger is connected to circulation pipes. There are at least two circulation pipes, one end of which is connected to the collector.

[0007] By adopting the above technical solution, multiple panels are spliced ​​to form the box body. The connection of inserts and slots increases the box body's sealing performance and overall structural stability, ensuring the box body's heat insulation performance. The box cover is placed and fixed screws are inserted. The fixed screws pass through multiple panels and are threaded to the bottom of the box, ensuring a tight connection between the panels. The staggered arrangement of the joints between two adjacent horizontal panels increases the overall structural stability of the box body. The inner tank inside the box body increases the sealing performance of the hot water storage tank. The inner tank, made of flexible material, facilitates transportation and installation. The modular design of the hot water storage tank reduces the space occupied by the solar thermal storage system during transportation, making it easier to transport and assemble the hot water storage tank. The splicing of the panels and the use of fixed screws to connect the bottom and the cover of the box facilitates the installation of the hot water storage tank and reduces the transportation and assembly costs of the solar thermal storage system.

[0008] Optionally, the solar collector includes a solar collector manifold, on which glass tubes are inserted. At least two glass tubes are spaced apart. A medium tube is inserted inside the solar collector manifold. At least two medium tubes are spaced apart. A solar collector tube is connected between the two medium tubes.

One end of the solar collector tube is located inside the glass tube. The two ends of the medium tube are respectively connected to the two circulation tubes.

[0009] By adopting the above technical solution, the collector uses a single medium tube bent and connected in series with multiple glass tubes inside, which can improve the heat conduction efficiency of the collector, reduce the weight of the collector, facilitate transportation and installation, and reduce the transportation and assembly costs of the solar thermal storage system.

[0010] Optionally, a reinforcing layer is fixed to the outer wall of the enclosure.

[0011] By adopting the above technical solution, the reinforcement layer of the outer wall of the hot water storage tank can increase the tightness of the connection between the tank panels, improve the sealing performance of the hot water storage tank, prevent rainwater, dust and debris from entering the gaps in the outer wall of the hot water storage tank, extend the service life of the hot water storage tank, and improve the aesthetics of the hot water storage tank.

[0012] Optionally, the housing is fitted with fixing clamps, and at least two fixing clamps are spaced at intervals.

[0013] By adopting the above technical solution, the fixing clamps can increase the stability of the connection between the tank panels, increase the overall structural strength of the hot water storage tank, and reduce the risk of the hot water storage tank loosening due to vibration or external force.

[0014] Optionally, the two fixing clamps are connected together to a fixing plate.

[0015] By adopting the above technical solution, the fixing plate can connect multiple fixing clamps, increase the overall structural strength of the hot water storage tank, and form a mesh fixing structure with the fixing clamps, reducing the risk of the fixing clamps loosening and slipping due to thermal expansion and contraction, and ensuring the safety and stability of the hot water storage tank.

[0016] Optionally, both the box cover and the box bottom are threadedly connected with fixing screws, and multiple fixing screws are spaced apart, with one end of each fixing screw abutting against both ends of the multiple fixing screw rods.

[0017] By adopting the above technical solution, the fixing screws can fix both ends of the fixing screw rod inside the bottom and cover of the tank, sealing both ends of the fixing screw rod and preventing rainwater, dust and debris from entering the gap between the fixing screw rod and the hot water storage tank, thus ensuring the overall safety and stability of the hot water storage tank.

[0018] Optionally, an insulation cover is fixedly connected to the box cover, and a water supply pipe and a breathing pipe are threaded through the insulation cover, and a domestic water pipe is threaded through the insulation cover.

[0019] By adopting the above technical solutions, the water supply pipe installed on the insulation cover facilitates the replenishment of water into the hot water storage tank, the breather pipe can balance the air pressure inside and outside the hot water storage tank, ensuring the safety and stability of the hot water storage tank's operation, and the domestic water pipe can directly provide hot water for domestic use, reducing the heat energy consumption caused by heating domestic water, while replenishing water into the hot water storage tank and reducing impurities generated by the hot water storage tank during long-term use.

[0020] Optionally, a drain pipe is connected to the bottom of the hot water storage tank.

[0021] By adopting the above technical solution, the drain pipe can easily remove impurities deposited at the bottom of the hot water storage tank, making it easier to clean and maintain the hot water storage tank and ensuring the safety and stability of the solar thermal storage system.

[0022] In summary, this application has the following technical effects: 1.
