[0038] Please refer to Figure 1 and Figure 2 , a heating water tank 200 provided by an embodiment of the present utility model is used for a heating device. The heating water tank 200 includes a water tank 201 and a heat exchange tube 202. The heat exchange tube 202 includes a main body portion 203 and two interface end portions 204. The main body portion 203 connects the two interface end portions 204, the main body portion 203 is located inside the water tank 201, and the interface end portions 204 penetrate through the top of the water tank 201.

[0039] Specifically, the heating device includes a heating water tank 200, a pipeline system and a heat source assembly. During the heating process, the heat source assembly transfers the generated heat to a medium (heat carrier), and these heat carriers (such as water or air) flow in the pipeline system to transport the heat to the heating water tank 200. In the heating water tank 200, the heat exchange tube 202 causes the heat carrier flowing in the tube to exchange heat with the water in the water tank 201 under the action of heat conduction so that the water in the water tank 201 is heated. Among them, the heat source assembly is responsible for generating heat, and the heat source assembly includes but is not limited to gas boilers, electric heaters, heat pumps, solar collectors, etc. The heat source assembly converts fuel (such as natural gas, fuel oil, electricity, solar energy, etc.) into heat energy to heat the medium (heat carrier), that is, transfers the generated heat to the medium (heat carrier).

[0040] The water tank 201 is a container for storing water to be heated. The heat exchange tube 202 is a pipe with a heat medium flowing inside, responsible for transferring the heat of the heat medium to the water in the water tank 201, thereby raising the water temperature and providing hot water. The main body part 203 is the main part of the heat exchange tube 202, located inside the water tank 201, and is the area where heat exchange occurs between the heat medium and the water in the water tank 201. The interface ends 204 are the two end parts of the heat exchange tube 202. The two interface ends 204 are respectively connected to both ends of the main body part 203. The two interface ends 204 and the main body part 203 together form the heat exchange tube 202. The interface ends 204 are used to connect to an external pipe system so that the heat medium can enter the heat exchange tube 202 and be discharged from the heat exchange tube 202 after heat exchange to continue circulating. Among them, the water tank 201 includes an inlet, an outlet and a sewage outlet. The inlet is connected to the inside of the water tank 201 for injecting cold water into the water tank 201. The outlet is connected to the inside of the water tank 201 for delivering the heated hot water. The sewage outlet is an opening located near the bottom of the side wall of the water tank 201 for discharging sediments or sewage in the water tank 201.

[0041] Since the heat exchange tube 202 is usually made of materials such as metals or alloys with good thermal conductivity, the weight of the heat exchange tube 202 is relatively heavy. When the interface ends 204 extend out from the side wall of the water tank 201, the heat exchange tube 202 will exert a vertically downward gravity on the side wall through the interface ends 204, and at the same time, the side wall will exert a vertically upward supporting force on the interface ends 204, resulting in uneven stress on the side wall and the heat exchange tube 202 and local stress concentration, thereby affecting the stability and service life of the overall structure. At the same time, in order to ensure the supporting strength of the side wall of the water tank 201, the aperture of the heat exchange tube 202 passing through the side wall of the water tank 201 cannot be too large. Especially when the wall thickness of the side wall is relatively thin, if the aperture of the heat exchange tube 202 passing through the side wall of the water tank 201 is too large, it will weaken the structural strength of the side wall of the water tank 201, resulting in deformation or damage of the side wall due to reduced supporting force.

[0042] In addition, since a large amount of water is stored inside the water tank 201 during operation, the entire heating water tank 200 is usually very heavy. Especially in industrial applications, due to large demand, the specifications of the heating water tank 200 are also large, and the entire heating water tank 200 is even heavier. Therefore, in order to provide better stability, the water tank 201 is usually directly placed on the ground so that the ground can evenly bear the weight of the heating water tank 200. When the interface ends 204 extend out from the bottom of the water tank 201, in order to provide sufficient space, it is necessary to add a footrest to prevent the interface ends 204 from being unable to extend out to connect to the external pipe system, thereby increasing additional material and construction costs. At the same time, the footrest may have poor stability, and it may be difficult to access and maintain the interface ends 204 passing through the bottom of the water tank 201, especially when the structure of the footrest is complex or the space is narrow.

[0043] In summary, in the above heating water tank 200, the two interface ends of the heat exchange tube 202 penetrate through the top of the water tank 201, so that the heat exchange tube 202 can penetrate out from the top of the water tank 201, which can effectively solve the problem of uneven stress, optimize the component layout at the same time, increase the flexibility of the diameter selection of the heat exchange tube 202, reduce the risk of deformation of the heat exchange tube 202 or the water tank 201, and simplify the installation process.

[0044] Optionally, the material of the heat exchange tube 202 has good heat conduction performance and corrosion resistance. For example, low-carbon steel, stainless steel, copper, aluminum alloy, etc.

[0045] Furthermore, please refer to Figures 1 to 5 , in some embodiments, the water tank 201 includes a barrel body 205, an upper head 206 and a lower head 207. The upper head 206 and the lower head 207 are respectively arranged at both ends of the barrel body 205 along the length direction. An installation joint 208 is provided on the upper head 206. The installation joint 208 is provided with an installation hole 209 communicating with the inside of the water tank 201. The installation hole 209 at least includes a combined section hole 210. The combined section hole 210 is tapered along the direction away from the inside of the water tank 201. The interface end 204 includes a combined part 211. The shape of the combined part 211 is adapted to the shape of the combined section hole 210 and abuts against the hole wall of the combined section hole 210 to limit the heat exchange tube 202.

[0046] Specifically, the barrel body 205 of the water tank 201 is the main container part, which can be made of corrosion-resistant and high-strength materials to withstand the pressure of the internal water and the load of long-term use. The upper head 206 and the lower head 207 are respectively installed at both ends of the barrel body 205, playing the roles of closing and supporting. Optionally, the upper head 206 and the lower head 207 can be disassembled for easy maintenance and repair. An installation joint 208 is provided on the upper head 206 so that the heat exchange tube 202 can penetrate out from the top of the water tank 201 and be connected to the external pipeline system.

[0047] The installation hole 209 in the installation joint 208 is provided with a combined section hole 210, and the aperture of the combined section hole 210 gradually decreases upward. A protruding combined part 211 is provided on the outer wall of the pipe wall of the interface end 204, and the combined part 211 is more convex along the direction close to the inside of the water tank 201. During the process of the interface end 204 penetrating out of the top of the water tank 201 from the inside of the water tank 201, the combined part 211 of the interface end 204 abuts against the combined section hole 210 of the installation hole 209. Since the aperture of the combined section hole 210 gradually decreases upward, when the interface end 204 moves upward, the increasingly tight aperture will limit the continuous upward movement of the increasingly convex combined part 211, that is, limit the fixed position of the heat exchange tube 202.

[0048] In the above embodiments, the fixing position of the heat exchange tube 202 is defined by the joint portion 211 and the joint section hole 210, so that the heat exchange tube 202 can be stably fixed at the designed position, preventing loosening caused by external force or vibration to a certain extent, thereby improving the stability of the overall structure.

[0049] As Figure 6 shown, optionally, when the heat exchange tube 202 moves to the fixing position, the heat exchange tube 202 and the mounting joint 208 can be welded, so that the outer wall of the heat exchange tube 202 is fixedly connected to the mounting joint 208, thereby preventing the heat exchange tube 202 from moving downward due to gravity and fixing it at the designed position. Optionally, the outer wall of the heat exchange tube 202 has threads. When the heat exchange tube 202 moves to the fixing position, it can be fastened by the cooperation of a nut with the threads on the outer wall of the heat exchange tube 202, so that the heat exchange tube 202 is fixed at the designed position due to the abutment of the nut against the mounting joint 208.

[0050] Furthermore, please refer to Figure 4 , in some embodiments, the joint section hole 210 is conical.

[0051] It can be understood that the joint section hole 210 can be regarded as a part of a cone with an internal cavity. When the cone angle is smaller, the aperture of the joint section hole 210 contracts upward more slowly. When the cone angle is larger, the aperture of the joint section hole 210 contracts upward faster. Among them, the cone angle is the angle between the side surface of the cone and the cone axis. Optionally, the cone angle is greater than 0° and less than 90°.

[0052] In the above embodiments, when the conical joint section hole 210 is in close contact with the joint portion 211 of the interface end 204, the gradually shrinking aperture can define the fixing position of the heat exchange tube 202, while improving the sealing performance and reducing the leakage risk.

[0053] Furthermore, please refer to Figure 1 and Figure 2 , in some embodiments, the upper head 206 is in a circular arc shape protruding upward.

[0054] Specifically, the shape of the upper head 206 is an upwardly protruding arc, and its arc can be a partial circle or other arc shapes (such as an elliptical arc).

[0055] During the heating process, the water pressure in the water tank 201 may rise due to the increase in water temperature. Since the circular arc has strong structural stability, the circular arc-shaped upper head 206 can better withstand the increase in internal pressure caused by the increase in water temperature, preventing deformation or damage.

[0056] In the above embodiments, the circular arc-shaped upper head 206 can enhance the structural stability, improve the strength and durability.

[0057] Further, please refer to Figures 4 to 6 , in some embodiments, the mounting hole 209 includes a first-stage hole 212 and a second-stage hole 213. The first-stage hole 212 is connected to one end of the combined-section hole 210 close to the inside of the water tank 201, and the second-stage hole 213 is connected to the other end of the combined-section hole 210 away from the inside of the water tank 201. The interface end 204 includes a first part 214 and a second part 215. The first part 214 is connected to one end of the joint part 211 close to the inside of the water tank 201, and the second part 215 is connected to the other end of the joint part 211 away from the inside of the water tank 201;

[0058] The shape of the first part 214 is adapted to the shape of the first-stage hole 212 and is in close contact with the hole wall of the first-stage hole 212;

[0059] The shape of the second part 215 is adapted to the shape of the second-stage hole 213 and is in close contact with the hole wall of the second-stage hole 213.

[0060] Specifically, the mounting hole 209 in the mounting joint 208 is provided with a first-stage hole 212 and a second-stage hole 213. The first-stage hole 212 and the second-stage hole 213 are located outside the water tank 201. The mounting joint 208 is fixedly connected to the outer edge of the water tank 201. The first-stage hole 212 is relatively close to the outer edge of the water tank 201, and the second-stage hole 213 is relatively far from the outer edge of the water tank 201. The first part 214 and the second part 215 are provided on the outer wall of the pipe wall of the interface end 204.

[0061] During the process of the interface end 204 passing through the top of the water tank 201 from the inside of the water tank 201, the second part 215 of the interface end 204 will pass through the combined-section hole 210 of the mounting hole 209 to reach the second-stage hole 213 and be in close contact with the hole wall of the second-stage hole 213. At the same time, the joint part 211 of the interface end 204 abuts against the combined-section hole 210 of the mounting hole 209 to limit the heat exchange tube 202 from continuing to pass through the top of the water tank 201, and at the same time, the first part 214 is in close contact with the hole wall of the first-stage hole 212.

[0062] It can be understood that the first-stage hole 212 and the second-stage hole 213 are guiding sections, which are used to provide a stable path for the heat exchange tube 202 to pass through the top of the water tank 201, and at the same time reduce the possible wear and pressure on the heat exchange tube 202 at the top of the water tank 201.

[0063] In the above embodiments, the first-stage holes 212 and the second-stage holes 213 can guide the heat exchange tube 202 (interface end 204) through the top of the water tank 201, ensuring that the heat exchange tube 202 can accurately and stably pass through the water tank 201 and be connected to the external pipeline system. At the same time, the first-stage holes 212 and the second-stage holes 213 are tightly adapted to the first part 214 and the second part 215 respectively, ensuring a good seal between the interface end 204 of the heat exchange tube 202 and the mounting hole 209 of the water tank 201.

[0064] In one embodiment, please refer to Figures 7 to 9 , the mounting hole includes a second-stage hole 213 and a combined-section hole 210. Correspondingly, a second part 215 and a combined part 211 are provided on the outer wall of the interface end 204. During the process of the interface end 204 passing through the top of the water tank 201 from the inside of the water tank 201, the second part 215 of the interface end 204 will pass through the combined-section hole 210 to reach the second-stage hole 215 and be in close contact with the hole wall of the second-stage hole 213. At the same time, the combined part 211 of the interface end 204 abuts against the combined-section hole 210 to limit the heat exchange tube 202 from continuing to pass through the top of the water tank 201.

[0065] Furthermore, please refer to Figure 2 , in some embodiments, the heating water tank 200 includes a reinforcing strip 216. The main body part 203 is coiled to form a cylinder, and the reinforcing strip 216 is connected to the outer side surface of the cylinder along the length direction of the cylinder.

[0066] Specifically, the main body part 203 of the heat exchange tube 202 gradually forms a continuous cylindrical structure through spiral coiling, that is, the cylinder. The reinforcing strip 216 is a component attached to the outside of the cylinder to enhance the structural strength of the cylinder. It is made of a strong material, such as steel or other high-strength alloys. The reinforcing strip 216 is fixedly connected to the cylinder along the length direction of the cylinder through welding or other fixing methods, which can provide additional support and prevent the cylinder from deforming or failing to a certain extent. That is, to a certain extent, it can prevent the position of the heat exchange tube 202 from changing when it is subjected to external pressure or long-term use.

[0067] It can be understood that the reinforcing strip 216 is connected to the cylinder formed by coiling the heat exchange tube 202 at multiple connection points. Since the cylinder is formed by spiral coiling and the reinforcing strip 216 is connected to the heat exchange tube 202 along the length direction of the cylinder, the reinforcing strip 216 contacts and is fixed to the cylinder at multiple positions.

[0068] It can be understood that the heating water tank 200 can include at least one reinforcing strip 216. When there are multiple reinforcing strips 216, the multiple reinforcing strips 216 are distributed circumferentially along the cylinder and are fixedly connected to the outer side surface of the cylinder respectively. The distances between the respective reinforcing strips 216 can be equal or unequal.

[0069] In the above embodiments, the heat exchange tube 202 can be ensured to maintain a stable cylindrical structure through the reinforcing strip 216, reducing the situation of unstable fixation of the heat exchange tube 202 to a certain extent.

[0070] Optionally, the reinforcing strip 216 can be strip-shaped or ribbon-shaped, and the cross-section can include but is not limited to rectangle, circle, T-shape, etc. The reinforcing strip 216 can be fixed to the outer side surface of the cylinder by welding, riveting or bonding.

[0071] Furthermore, please refer to Figure 2 In some embodiments, hooks are respectively formed at both ends of the reinforcing strip 216.

[0072] Specifically, the hook 217 is a bent or hook-shaped structure designed at both ends of the reinforcing strip 216, which is used to help fix the reinforcing strip 216 and ensure its stable connection with the heat exchange tube 202 during production or assembly. The hook 217 can be effectively hooked on specific installation points to support the reinforcing strip 216 in an upright position, so as to ensure that the reinforcing strip 216 remains stable during the process of fixedly connecting the heat exchange tube 202 and the reinforcing strip 216.

[0073] In the above embodiments, the reinforcing strip 216 can be stably fixed at a specific position through the hook 217 during production and assembly, thus simplifying the installation. At the same time, it ensures that the reinforcing strip 216 and the heat exchange tube 202 can be kept in the correct position during connection, improving the assembly accuracy and production efficiency.

[0074] Furthermore, please refer to Figure 2 In some embodiments, the heating water tank 200 includes a limiting device 218, which is arranged in the water tank 201, and the limiting device 218 connects the reinforcing strip 216 and the inner surface of the water tank 201.

[0075] Specifically, the limiting device 218 can be a limiting block, which is located between the inner surface of the water tank 201 and the heat exchange tube 202. By connecting with the reinforcing strip 216, it is connected to the outer side surface of the cylinder formed by coiling the heat exchange tube 202, and is used to limit the fixing position of the heat exchange tube 202. Since there is a certain space between the outer side surface of the cylinder formed by coiling the heat exchange tube 202 and the inner surface of the water tank 201, the heat exchange tube 202 may change its position due to external pressure or vibration, resulting in wear. Therefore, in order to fix the heat exchange tube 202, the space between the outer side surface of the cylinder and the inner surface of the water tank 201 can be filled by the limiting device 218.

[0076] It can be understood that since the reinforcing strip 216 is connected to the outer side surface of the cylinder formed by coiling the heat exchange tube 202, the limiting device 218 can be connected to the outer side surface of the cylinder formed by coiling the heat exchange tube 202 by connecting with the reinforcing strip 216.

[0077] It is understandable that the limiting device 218 is connected to the cylinder formed by coiling the heat exchange tube 202 at at least one connection point.

[0078] In the above embodiments, the fixed position of the heat exchange tube 202 can be limited by the limiting device 218, so as to avoid problems such as wear caused by unstable fixation of the heat exchange tube 202 to a certain extent.

[0079] Optionally, the heating water tank 200 may include at least one limiting device 218. When there are multiple limiting devices 218, the multiple limiting devices 218 are respectively connected to multiple reinforcing bars 216.
