Description

Technical Field

[0001] This utility model relates to the technical field of heating and heating equipment, specifically an integrated manifold and heating device for solar-powered pressureless heating water distribution and diversion. Background Technology

[0002] In existing technologies, solar thermal vacuum tube heating devices are independent heating equipment used by households, businesses, and other users. The integrated water distribution manifold for solar pressureless heating includes a strip-shaped manifold body with an inlet pipe at the bottom and a return pipe at the top. Multiple vacuum tubes connected to the inside of the manifold body are located on both sides. The manifold body is equipped with an insulation layer for heat preservation and frost protection. The manifold body connects to the vacuum tubes and distributes water flow into them. Traditionally, the manifold body is hollow and placed at an angle. Pressurized water enters the manifold body through the inlet pipe at the bottom, flowing upwards through the manifold body to the vacuum tubes at both ends until the entire manifold body and vacuum tubes are full. Finally, the hot water returns to the ground-level water tank, providing circulating hot water for indoor heating systems to achieve the purpose of heating. Its disadvantages are: pressurized water entering the vacuum tubes can easily cause impact, potentially leading to tube breakage and leakage. A utility model patent entitled "Unpressurized Water Diversion and Guiding Solar Double-Wing Manifold" was disclosed in the specification of Chinese utility model patent on September 1, 2023, with patent number ZL 202320319492.5. It includes a manifold with an inner liner, several connection ports on both sides of the manifold, a vacuum tube connected to the connection ports, and a sealed connection between the vacuum tube and the inner liner. An insulation layer is filled on the outside of the inner liner, and a conduit connects the insulation layer to the inner liner. A water guide pipe is located inside the vacuum tube. A steel wire is installed on the central axis of the inner liner, and a fulcrum is provided at one end of the water guide pipe, which is vertically welded to the steel wire. Its disadvantages include complex structure and cumbersome connection due to the water guide pipes being fixed one by one by welding with steel wire; the partitions are not set to correspond to the water guide pipes, resulting in unstable water inflow into each water guide pipe and potential impact on the vacuum tube, posing a risk of pipe bursting. Utility Model Content

[0003] The purpose of this utility model is to provide a solar-powered pressureless heating water distribution and diversion integrated manifold and heating device with a reasonable structure and good performance in order to address the above-mentioned shortcomings.

[0004] The technical solution of this utility model is: a solar pressureless heating water distribution and diversion integrated manifold, including a manifold body, an inlet pipe at the upper end of the manifold body, a return pipe at the lower end of the manifold body, and multiple vacuum tubes connected to the side wall of the manifold body. Multiple water distribution partitions connected to the inner wall are arranged at intervals along the length of the manifold body, and each water distribution partition has one or more water guide pipes that pass through the side wall of the manifold body and extend into the inner end of the vacuum tubes connected to the manifold body.

[0005] The above plan also includes:

[0006] The water-dividing partition is a water-dividing trough. Each side wall of the water-dividing trough has a water outlet, which is connected to a water guide pipe. The water guide pipe has a vacuum tube connection port on each side wall of the connecting box, and the vacuum tube is connected to the vacuum tube connection port.

[0007] The water-separating partition is a partition plate with a water outlet on its surface. The water outlet is connected to a water pipe, and the water pipe has a vacuum tube connection port on each of the two side walls of the connecting box. The vacuum tube is connected to the vacuum tube connection port.

[0008] The water-separating partition is a partition plate. Each side wall of the manifold on both sides of the partition plate has a water outlet. The water outlet is connected to a water guide pipe. The water guide pipe has a vacuum tube connection port on each side wall of the manifold. The vacuum tube connection port is located between the upper and lower parts of the partition plate, and the vacuum tube is connected to the vacuum tube connection port.

[0009] The aforementioned manifold body is equipped with an insulation layer.

[0010] The solar-powered pressureless heating water distribution and diversion heating device is equipped with an integrated solar-powered pressureless heating water distribution and diversion manifold.

[0011] The advantages of this utility model are: 1. The manifold with vacuum tubes is angled, and because a water-dividing layer is set corresponding to the vacuum tubes, water flows naturally from top to bottom layer by layer after the ground water comes in. The water enters each vacuum tube sequentially and accurately, ensuring stable water flow and preventing impact on the vacuum tubes, thus avoiding tube bursting and reducing the occurrence of failures. 2. The manifold and its upper structure are made of integral plastic molding, with a reasonable structure. During assembly, only the vacuum tubes and water guide pipes need to be connected, ensuring reliable use.

[0012] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0019] See Figure 1 , 2 Figure 3 is a schematic diagram of the longitudinal section of the manifold 1 (no section lines are drawn, the same below). The solar pressureless heating water distribution and diversion integrated manifold includes a long strip-shaped manifold 1, with an insulation layer on the manifold 1 (figure omitted). The upper end of the manifold 1 has a water inlet pipe 2, and the lower end of the manifold 1 has a water return pipe 3. There are multiple vacuum tubes 4 (glass tubes) on both sides of the manifold 1 that are connected to the side walls of the manifold 1. For example, there are 25 vacuum tubes on one side, and a total of 50 vacuum tubes on both sides. The manifold 1 contains multiple water-distributing partitions arranged along its length, connected to the inner wall. These partitions are U-shaped water-distributing channels 5, each with connecting lugs 8 on both sides. Each side wall of the water-distributing channel 5 has an outlet 9, which connects to a water guide pipe 6. Corresponding to the water guide pipes 6 on the side walls of the manifold 1 are vacuum tube connection ports 10. Vacuum tubes 4 connect to these ports 10, with the connection ports 10 being larger than the outlets 9. The water guide pipe 6 passes through the vacuum tube opening 14 and extends into the inner end of the vacuum tube 4 connected to the manifold 1. Water entering the inner end of the vacuum tube 4 through the water guide pipe 6 flows through the gap between the water guide pipe 6 and the vacuum tube 4, flowing from the vacuum tube opening 14 into the next water-distributing channel 5, and so on. The manifold 1 and its upper structure are integrally molded from plastic, with a reasonable structure. Assembly only requires connecting the vacuum tubes 4 and water guide pipes 6, ensuring reliable operation. A sealing ring is provided between the vacuum tube 4 and the vacuum tube connection port 10. The connection between vacuum tube 4 and manifold 1 can be slightly tilted downwards. When the pump stops, residual water will remain inside the vacuum tube 4. When water is suddenly added to the vacuum tube 4, cold water should be prevented from contacting the hot empty tube to avoid causing the tube to burst.

[0020] The manifold 1 and the left and right vacuum tubes 4 form a unit, such as... Figure 1 As shown. Multiple installations can be laid depending on the heating area, and multiple manifold units 1 can be interconnected, such as... Figure 3 As shown. Multiple manifolds 1 can also be combined with vacuum tube bundles, and are not limited to this. The manifold 1 is placed at an angle or vertically, and water from the ground flows naturally from top to bottom, ensuring stable operation and preventing tube bursts.

[0021] See Figure 1 , 23. Water Inlet Path: The manifold 1 is placed at an angle, facing the sun. The inlet pipe 2 is at the top of the manifold 1, and the return pipe 3 is at the bottom. Water flows naturally downwards from the top of the manifold 1. Ground water → inlet pipe 2 → water distribution trough 5 → outlet 9 → guide pipe 6 → vacuum pipe 4 → vacuum pipe inlet 14 → next water distribution trough 5 → and so on → return pipe 3 → back to the ground-level hot water collection tank.

[0022] See Figure 4 The water-separating partition is a partition 11 with a drain outlet 12 on its surface. The drain outlet 12 is connected to a water guide pipe 6. The water guide pipe 6 has vacuum tube connection ports 10 on both sides of the connecting tank. The vacuum tube 4 is connected to the vacuum tube connection port 10. The water inlet path is: ground water → water inlet pipe 2 → partition 11 → drain outlet 12 → water guide pipe 6 → vacuum tube 4 → vacuum tube port 14 → next partition 11 → and so on → return water pipe 3 → back to the ground water collection tank.

[0023] See Figure 5 The water distribution partition is a partition 11. Each side wall of the manifold on both sides of the partition 11 has a water outlet 13, which connects to a water guide pipe 6. Corresponding to the two side walls of the manifold, the water guide pipe 6 has a vacuum tube connection port 10. The vacuum tube connection port 10 is located between the upper and lower surfaces of the partition 11, and the vacuum tube 4 is connected to the vacuum tube connection port 10. The water inlet path is: ground water → inlet pipe 2 → partition 11 → water outlet 13 → water guide pipe 6 → vacuum tube 4 → vacuum tube port 14 → next partition 11 → and so on → return pipe 3 → back to the ground-level hot water collection tank.

[0024] The solar thermal vacuum tube heating device is equipped with a solar pressureless heating water distribution and diversion integrated manifold and other conventional supporting heating components and facilities for heating. Any auxiliary heating devices not mentioned are conventional technologies.

[0025] The above description is merely a specific embodiment of this utility model, and the various examples do not constitute a limitation on the substantive content of this utility model.
