Description

Technical Field

[0001] This utility model relates to the field of hot water tank heating technology, specifically a centralized heating structure. Background Technology

[0002] Hot water tank heating systems are a widely used heating method. Their core principle is to heat water stored in a sealed tank to meet users' daily hot water needs. This system is typically equipped with a temperature control device and insulation layer to maintain a stable water temperature and reduce energy consumption. Hot water tank heating systems are simple in structure, easy to install, and have low initial investment and operating costs, making them suitable for homes, small shops, offices, and other similar locations. Furthermore, the system allows for selection of different capacities and heating methods, such as electric heating, gas heating, or solar-assisted heating, offering flexibility and adaptability.

[0003] However, traditional heating methods use a single heat source to heat the entire tank of water. Heat needs to be transferred through natural convection or conduction in the water medium. This mode easily leads to uneven water temperature distribution within the tank, with water near the heat source being too hot and water further away (especially at the bottom and edges of the tank) being too cold. To ensure that the water temperature in all areas reaches the set operating temperature, it is often necessary to extend the heating time or increase the heating power, resulting in energy waste. To address this, a centralized heating structure is proposed. Utility Model Content

[0004] Based on this, the present invention aims to at least solve one of the technical problems existing in the prior art. To this end, a centralized heating structure is proposed, which can efficiently heat the water in a hot water tank to reduce energy consumption.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a centralized heating structure, including a barrel body, a support frame fixed at the bottom edge of the barrel body, a pressure relief head assembled at the top of the barrel body, and a heat exchange assembly installed inside the barrel body; The heat exchange assembly includes heat exchange tubes disposed within the tank body. The heat exchange tubes include multiple sets of unit heat exchange tubes evenly distributed along the height direction of the tank body. Each set of unit heat exchange tubes includes two sets of disc-shaped heat exchange groups. Each disc-shaped heat exchange group includes an outer ring tube. An inner ring tube is provided on the inner side of the outer ring tube. Multiple sets of L-shaped diversion tubes connected to the inner ring tubes are provided on the outer wall of the outer ring tube along its circumference. Multiple sets of arc-shaped diversion tubes are connected on the outer wall of each set of L-shaped diversion tubes along its circumference. Two sets of branch pipes connected to the unit heat exchange tubes are provided at the center of the tank body. The ends of the two sets of branch pipes are connected to water inlet pipes extending to the outside of the tank body.

[0006] According to some embodiments of the present invention, the outer wall of the barrel is provided with a return pipe that is connected to the unit heat exchange tube, and the return pipe can discharge the heat source inside the unit heat exchange tube to the outside.

[0007] According to some embodiments of the present invention, the outer wall of the branch pipe is provided with a connecting pipe that communicates with the outer ring pipe of the upper layer, and the outer ring pipe of the lower layer is connected with the return pipe.

[0008] According to some embodiments of this utility model, the inner wall of the barrel is fixed with three sets of positioning strips along its circumference, and the outer wall of the positioning strips is fixed to the load-bearing plate covering the outer ring tube by bolts.

[0009] According to some embodiments of this utility model, the upper and lower ends of the barrel are provided with through holes, the top of the barrel is fixed with a top cover that blocks the through holes by bolts, and the pressure relief head is assembled on the top of the through holes.

[0010] According to some embodiments of this utility model, the support frame is fixed to the barrel body with bolts, and the outer wall of the support frame can be welded with ear plates and fixed to the ground with the help of expansion bolts.

[0011] In summary, the present invention has the following main advantages: This invention achieves a layered and uniform distribution of heat source within the tank by employing a multi-unit heat exchange tube and disc-shaped heat exchange assembly design. The heat source enters the unit heat exchange tubes from the inlet pipe via branch pipes, flowing upwards and downwards simultaneously.

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0015] The embodiments of this utility model will be described below based on its overall structure.

[0016] A centralized heating structure, such as Figures 1 to 5 As shown, it includes a barrel body 100, a support frame 110 fixed at the bottom edge of the barrel body 100, a pressure relief head 130 assembled at the top of the barrel body 100, and a heat exchange assembly 200 installed inside the barrel body 100. The heat exchange assembly 200 includes heat exchange tubes 210 disposed within the tank body 100. The heat exchange tubes 210 include multiple sets of unit heat exchange tubes 250 evenly distributed along the height direction of the tank body 100. Each set of unit heat exchange tubes 250 includes two sets of disc-shaped heat exchange groups 260. The disc-shaped heat exchange group 260 includes an outer ring tube 261. An inner ring tube 262 is provided on the inner side of the outer ring tube 261. Multiple sets of L-shaped diversion tubes 263 connected to the inner ring tube 262 are provided on the outer wall of the outer ring tube 261 along its circumference. Multiple sets of arc-shaped diversion tubes 264 are connected on the outer wall of each set of L-shaped diversion tubes 263 along its circumference. Two sets of branch tubes 241 connected to the unit heat exchange tubes 250 are provided at the center of the tank body 100. The ends of the two sets of branch tubes 241 are connected to water inlet pipes 240 extending to the outside of the tank body 100.

[0017] The outer wall of the barrel 100 is provided with a return pipe 230 that is connected to the unit heat exchange tube 250. The return pipe 230 can discharge the heat source inside the unit heat exchange tube 250 to the outside.

[0018] The outer wall of the branch pipe 241 is provided with a connecting pipe 242 that is connected to the upper outer ring pipe 261, and the lower outer ring pipe 261 is connected to the return pipe 230.

[0019] It is worth noting that the heat exchange component 200 is made of copper-nickel alloy, which can accelerate the transfer of heat, and hot air is introduced into the heat exchange component 200 to heat the water in the tank 100. The L-shaped distribution tubes 263 in the upper and lower sets of disc heat exchange groups 260 are in a staggered state; The heat source (steam) is delivered to the heat exchange assembly 200 through external equipment. The heat source first enters from the water inlet pipe 240 and flows into the two sets of branch pipes 241 respectively. The two heat sources flow upward and downward from the middle of the tank 100 respectively, and will enter each set of disc heat exchange groups 260 one by one through the connecting pipe 242, so that the water source in the tank 100 is divided into parts, and the water source at different horizontal heights is heated at the same time. After the heat source enters the disc-shaped heat exchanger 260, it first flows through the outer ring pipe 261 and is then diverted to the inner ring pipe 262 through multiple sets of L-shaped diversion pipes 263. At the same time, the heat source is further evenly diffused to the water near the inner wall of the barrel 100 through the arc-shaped diversion pipe 264. After completing the heat exchange, the heat source is collected along the outer ring pipe 261 of the lower unit heat exchanger 250 under the action of gravity, and finally discharged from the barrel 100 through the return pipe 230. After being heated by external equipment, it re-enters the barrel 100. This circulation path ensures that the heat source forms a two-way convection from bottom to top within the tank 100, and achieves three-dimensional uniform radiation of heat through a multi-level diversion structure, which better avoids uneven heating of the water source and thus shortens the heating time.

[0020] Please refer to this carefully. Figure 2 and Figure 5 The inner wall of the barrel 100 is fixed with three sets of positioning strips 220 along its circumference. The outer wall of the positioning strips 220 is fixed with bolts to the load-bearing plate 221 covering the outer ring tube 261.

[0021] The three sets of positioning strips 220 located on the inner wall of the tank 100 cooperate with the load-bearing plate 221 to stably suspend the disc heat exchanger 260 within the tank 100, preventing displacement caused by water flow impact.

[0022] Please refer to this carefully. Figure 1 The barrel body 100 has through holes 140 at both the upper and lower ends. The top of the barrel body 100 is fixed with a top cover 120 that blocks the through holes 140 by bolts. The pressure relief head 130 is assembled on the top of the through holes 140. The top of the top cover 120 is provided with a water inlet hole. The water inlet and the lower through hole 140 are connected to an external pipe, which can deliver the water to be heated into the tank 100 for heating treatment, and the heated water is discharged from the through hole 140.

[0023] The support frame 110 is fixed to the barrel 100 with bolts. The outer wall of the support frame 110 can be welded with ear plates and fixed to the ground with expansion bolts. Meanwhile, a high-temperature sensor can be installed on the top of the tank 100 to monitor the temperature changes of the internal water source in real time.
