Description

Technical Field

[0001] This invention relates to steel radiators, and more particularly to an automatic full-water maintenance type steel radiator. Background Technology

[0002] As a heating terminal product, heating radiators have a long history of development and have been continuously evolving and updated within the heating industry. From cast iron radiators to the lightweight radiators that are currently produced and sold in large quantities, such as copper-aluminum composite radiators, steel-aluminum composite radiators, and steel radiators, there are many varieties, each with its own characteristics and applications.

[0003] Most existing steel radiators are generally tubular structures, using round or irregularly shaped steel pipes. They come in single-pipe and multi-pipe configurations. Regardless of the structure, the biggest concern for manufacturers, distributors, and users is corrosion during use. This corrosion can lead to radiator failure or damage, especially the "waterline" corrosion caused by residual water after the heating season ends, which is a major culprit for leaks. This corrosion mechanism involves electrochemical and oxygen-enriched corrosion in the residual water. Because heating water quality varies, poor water quality can cause perforation in the radiator pipe walls, leading to leaks or damage.

[0004] To address this issue, research institutions and manufacturers have devised various methods, such as applying anti-corrosion coatings to the inner walls of the radiator cavity and installing reactive metal at the bottom of the radiator for electrostatic corrosion protection. In fact, a method for preventing corrosion in steel radiators was discovered long ago: the full-water maintenance method. However, traditional production and installation methods make it difficult to achieve full-water maintenance during application. Explaining and instructing users on full-water maintenance has proven ineffective in practice, primarily because users generally do not attempt to perform full-water maintenance when heating is stopped, possibly due to lack of knowledge or fear of inconvenience. Therefore, passively requiring users to perform full-water maintenance is impractical; a radiator that enables automatic full-water maintenance is urgently needed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an automatic full-water maintenance type steel radiator with enhanced corrosion resistance and improved service life.

[0006] To solve the above problems, the present invention provides an automatic full-water maintenance type steel radiator, characterized in that: the radiator comprises several single pieces connected together; several of the single pieces are provided with horizontal diverter plates, and one of the single pieces is provided with a vertical guide plate; a guide pipe is provided inside or outside the single piece at one end, or a guide pipe or pressure control valve is provided inside or outside the single pieces at both ends; the guide pipe is assembled by welding a connecting neck and a straight section of the guide pipe together with a threaded end.

[0007] Several of the single pieces near the inlet are provided with the horizontal diversion plate, which is located on the upper part of the corresponding single piece; the single piece near the return outlet is provided with the vertical guide plate on the upper part; the single piece with the return outlet is provided with a guide pipe, the top surface of which is provided with an anti-corrosion weir, and an air vent valve is installed on the top.

[0008] The single piece with the water inlet is provided with the guide pipe, and the top surface of the guide pipe is provided with the anti-corrosion weir.

[0009] Several of the single pieces near the inlet are provided with the transverse diversion plate, which is located on the upper part of the corresponding single piece; the single piece with the return water inlet is provided with a guide pipe on the outside, the top surface of the guide pipe is provided with an anti-corrosion weir, and an air vent valve is installed on the top.

[0010] The vertical guide plate is provided on the lower part of the single piece near the water inlet; the guide pipe is provided on the outer side of the single piece with the water inlet, and the anti-corrosion weir is provided on the top surface of the guide pipe.

[0011] Several of the single pieces near the inlet are provided with the horizontal diversion plate, which is located at the bottom of the corresponding single piece; the middle single piece is provided with the vertical guide plate at the bottom; the two outermost single pieces are provided with pressure control valves at the bottom of the inner wall or the bottom of the outer wall, which are connected to the inlet or outlet.

[0012] The vertical guide vane has a sheet-like blind plate structure.

[0013] The transverse diversion plate has a sheet-like perforated structure, and the size and number of its perforations are designed according to the principle of increasing flow rate.

[0014] Compared with the prior art, the present invention has the following advantages: 1. This invention changes the hot water circulation route of existing steel radiators.

[0015] Existing steel radiators have hot water circulation routes that are either large or small loops due to different connection methods between the external interface and the inlet / outlet pipes. For small loops, the radiator's heat dissipation performance is reduced, meaning it's lower than ideal. This invention, however, uses a flow guiding structure inside (or outside) the radiator to ensure it always operates in a large return water mode, which improves the radiator's performance.

[0016] 2. Compared with existing steel radiators, this invention can control the flow path of hot water into the radiator. When heating is stopped, the radiator can automatically reach the full water maintenance condition, which enhances the corrosion resistance of the radiator and improves its service life.

[0017] 3. The material used in this invention is carbon steel, which is cheaper than existing non-ferrous metal composite radiators, and its service life is not reduced, and even exceeds that of some composite radiators.

[0018] 4. The anti-corrosion weir in this invention can ensure that the inner cavity of the radiator is filled with medium water when the heating is stopped, thereby achieving the conditions for automatic full water maintenance.

[0019] 5. Because the present invention can achieve full-water maintenance conditions after the heating is turned off, the wall thickness of the radiator can also be reduced under the premise of using standard water quality for heating, for example, from 1.8mm to 1.2mm, thereby reducing the manufacturing cost of the product.

[0020] 6. Compared with existing radiators, the present invention simplifies the manufacturing process, such as eliminating the need for product pretreatment and internal anti-corrosion treatment, thus saving energy and protecting the environment.

[0021] 7. The automatic full-water maintenance steel radiator of this invention can successfully improve corrosion resistance, and can replace or eliminate non-ferrous metal radiators, thus avoiding the criticism caused by the large-scale use of non-ferrous metals in heating radiators. This is conducive to saving natural resources and increasing overall social benefits. At the same time, it is also convenient for people to choose and use. Attached Figure Description

[0030] An automatic full-water maintenance type steel radiator includes several interconnected individual sections 1; each section 1 has a horizontal diversion plate 5, and one section 1 has a vertical guide plate 4; a guide pipe 2 is provided inside or outside the section 1 at one end, or a guide pipe 2 or pressure control valve 3 is provided inside or outside the section 1 at both ends; the guide pipe 2 is assembled by welding a connecting neck 201 and a straight section 202, and then welded to a threaded end 6. This controls the flow path of hot water into the radiator, allowing the radiator to automatically reach full-water maintenance conditions when heating is stopped, improving the radiator's corrosion resistance and extending its service life.

[0031] In this invention, the vertical guide plate 4 and the horizontal diverter plate 5 work together to regulate the flow direction and flow rate of hot water within the radiator cavity. The vertical guide plate 4 is a sheet-like blind plate structure. The horizontal diverter plate 5 is a sheet-like perforated structure, with several distributed throughout the radiator, configured according to the size of the radiator. The size and number of the perforations are designed according to the principle of increasing flow rate.

[0032] The built-in (external) guide pipe 2 and the built-in vertical guide plate 4 are appropriately configured and distributed inside the radiator to scientifically control the flow path of hot water into the radiator, so as to achieve the condition of full water maintenance when heating is stopped, improve the corrosion resistance of the product, and thus increase the service life of the radiator product.

[0033] The built-in (external) pressure control valve 3 can intelligently determine whether heating has stopped and then shut off the water flow, thereby achieving the active full-water function.

[0034] Example 1 An automatic full-water maintenance type steel radiator includes several single pieces 1 connected together; several single pieces 1 near the water inlet are provided with horizontal diversion plates 5, which are located on the upper part of the corresponding single pieces 1; a vertical guide plate 4 is provided on the upper part of the single piece 1 near the water outlet; a guide pipe 2 is provided in the single piece 1 with the water outlet, the top surface of the guide pipe 2 is provided with an anti-corrosion weir 7, and an air vent valve 8 is installed on the top.

[0035] like Figure 1The diagram shows a basic example of the invention, a typical built-in flow guide structure. The water inlet and outlet are arranged in a large circulation pattern with top inlet and bottom outlet. The left side is the interface for hot water to flow into the radiator. Several horizontal flow dividers 5 are provided on the left side, each with water flow holes of different sizes to adjust the flow distribution effect, ensuring uniform hot water flow throughout the radiator cavity and improving heat dissipation efficiency. In specific manufacturing, for example, φ2mm holes are drilled, and sheet-like flow dividers are manufactured according to the designed distribution and quantity gradient. These are then welded to the corresponding positions of different individual sheets 1 according to design requirements to achieve uniform hot water flow. The right side of the radiator includes core technical components such as a flow guide pipe 2, a vertical flow guide plate 4, and an anti-corrosion weir 7. During manufacturing, it is crucial that the diameter of the flow guide pipe 2 is adapted to the radiator structure. If the diameter is too large, it will not only increase costs but also restrict the flow through the right-side radiator channel, affecting heat dissipation efficiency. A diameter between DN15 and DN20 is generally recommended. The vertical flow guide plate 4 can be designed as a sheet-like blind plate. The anti-corrosion weir 7 is designed in a cylindrical shape or other shape suitable for the radiator fins, depending on the selection of the guide pipe 2. A cylindrical shape is recommended for easier processing and maintenance. Wall thickness is a key design consideration for this component. If steel is used, the wall thickness should not be less than 3.5mm. If stainless steel or other corrosion-resistant materials are used, the wall thickness can be appropriately reduced. The design wall thickness should be based on a pressure resistance of not less than 1MPa. The connecting neck 201 of the guide pipe 2 is welded to the threaded end 6, and the straight guide pipe section 202 is connected to it, ensuring that the straight guide pipe section 202 extends 5mm above the highest dimension of the radiator. After these components are fabricated, they are welded or threaded onto the radiator body, completing the fabrication of the automatic full-water maintenance radiator.

[0036] Example 2: An automatic full-water maintenance type steel radiator, comprising several single sections 1 connected together; several single sections 1 near the water inlet are provided with horizontal diversion plates 5, which are located on the upper part of the corresponding single section 1; a vertical guide plate 4 is provided on the upper part of the single section 1 near the water return outlet; a guide pipe 2 is provided in the single section 1 with the water return outlet, the top surface of the guide pipe 2 is provided with an anti-corrosion weir 7, and an air vent valve 8 is installed on the top; a guide pipe 2 is provided in the single section 1 with the water inlet, and the top surface of the guide pipe 2 is provided with an anti-corrosion weir 7.

[0037] like Figure 2As shown, this is the first variation of the invention, featuring a built-in flow guide structure with a bottom-inlet and bottom-outlet configuration. The left and right sides are almost symmetrical. The left side is the inlet for hot water to flow into the radiator, and the right side is the inlet for hot water to flow out after heat exchange. Several horizontal diversion plates 5 are provided on the left side, each with water flow holes of different sizes to adjust the diversion effect and ensure uniform hot water flow throughout the radiator, thus improving heat dissipation efficiency. Specifically, in manufacturing, for example, φ2mm holes are drilled, and sheet-like diversion plates are manufactured according to the designed distribution and quantity gradient. These plates are then welded to corresponding positions on different individual plates 1 according to design requirements to achieve uniform hot water flow. Flow guide pipes 2 and anti-corrosion weirs 7 are provided on both the left and right sides of the radiator, and a vertical flow guide plate 4 is also provided on the right side. During manufacturing, it is crucial that the diameter of the flow guide pipe 2 is adapted to the radiator structure. If the diameter is too large, it will not only increase costs but also restrict the flow through the right-side radiator channel, affecting heat dissipation efficiency. A diameter between DN15 and DN20 is generally recommended. The vertical flow guide plate 4 can be designed as a sheet-like blind plate. The anti-corrosion weir 7 is designed in a cylindrical shape or other shape suitable for the radiator fins, depending on the selection of the guide pipe 2. A cylindrical shape is recommended for easier processing and maintenance. Wall thickness is a key design consideration for this component. If steel is used, the wall thickness should not be less than 3.5mm. If stainless steel or other corrosion-resistant materials are used, the wall thickness can be appropriately reduced. The design wall thickness should be based on a pressure resistance of not less than 1MPa. After these components are fabricated, they are welded or threaded onto the radiator body to complete the automatic full-water maintenance radiator.

[0038] Example 3 An automatic full-water maintenance type steel radiator, the radiator includes several single pieces 1 connected together; several single pieces 1 near the water inlet are provided with a horizontal diversion plate 5, the horizontal diversion plate 5 is provided on the upper part of the corresponding single piece 1; the single piece 1 with a return water inlet is provided with a guide pipe 2 on the outside, the top surface of the guide pipe 2 is provided with an anti-corrosion weir 7, and an air vent valve 8 is installed on the top.

[0039] like Figure 3The image shows a second variation of the invention, featuring an externally mounted, top-inlet, top-outlet flow structure. The left side serves as the inlet for hot water to flow into the radiator. Several horizontal diversion plates 5 are located on the left side, each with water flow holes of different sizes to adjust the flow distribution and ensure uniform hot water flow throughout the radiator, thus improving heat dissipation efficiency. In manufacturing, for example, φ2mm holes are drilled to create sheet-like diversion plates according to the designed distribution and quantity gradient. These plates are then welded to corresponding positions on different individual plates 1 according to design requirements to achieve uniform hot water flow. The right side of the radiator includes core components such as an external flow guide pipe 2. During manufacturing, it is crucial that the diameter of the flow guide pipe 2 is compatible with the radiator structure. An excessively large diameter not only increases cost but also restricts flow through the right-side radiator channel, affecting heat dissipation efficiency. A diameter between DN15 and DN20 is generally recommended. The straight section 202 of the flow guide pipe 2 must be at least 5mm higher than the highest dimension of the radiator to ensure full water flow. After the above components are manufactured, they are welded or wired to the radiator body to complete the production of the automatic full-water maintenance radiator.

[0040] Example 4: An automatic full-water maintenance type steel radiator, comprising several single sections 1 connected together; several single sections 1 near the water inlet are provided with horizontal diversion plates 5, which are located on the upper part of the respective single sections 1; a guide pipe 2 is provided on the outer side of the single section 1 with a return water inlet, the top surface of the guide pipe 2 is provided with an anti-corrosion weir 7, and an air vent valve 8 is installed on the top. A vertical guide plate 4 is provided in the lower part of the single section 1 near the water inlet; a guide pipe 2 is provided on the outer side of the single section 1 with a water inlet, the top surface of the guide pipe 2 is provided with an anti-corrosion weir 7.

[0041] like Figure 4The image shows a third variation of the invention, featuring an external guide pipe with a bottom-in, bottom-out structure. The left and right sides are almost identical. The left side is the interface for hot water to flow into the radiator. Several horizontal diversion plates 5 are provided on the left side, each with water flow holes of different sizes to adjust the diversion effect and ensure uniform hot water flow throughout the radiator, thus improving heat dissipation efficiency. In specific manufacturing, for example, φ2mm holes are drilled, and sheet-like diversion plates are manufactured according to the designed distribution and quantity gradient. These plates are then welded to corresponding positions on different individual plates 1 according to design requirements to achieve uniform hot water flow. Guide pipes 2 and anti-corrosion weirs 7 are provided on both the left and right sides of the radiator. During manufacturing, it is crucial that the diameter of the guide pipe 2 is compatible with the radiator structure. If the diameter is too large, not only will the cost increase, but it will also restrict the flow through the right-side radiator channel, affecting heat dissipation efficiency. A diameter between DN15 and DN20 is generally recommended. The anti-corrosion weir 7 is designed in a cylindrical shape or other shape suitable for the radiator fins, depending on the selection of the guide pipe 2. A cylindrical shape is recommended for easier processing and maintenance. Wall thickness is a key design consideration for this component. If steel is used, the wall thickness should not be less than 3.5mm. If stainless steel or other corrosion-resistant materials are used, the wall thickness can be appropriately reduced. The design wall thickness should be based on a pressure resistance of not less than 1MPa. The connecting neck 201 of the guide pipe 2 is welded to the threaded end 6, and the straight guide pipe section 202 is connected to it, ensuring that the straight guide pipe section 202 extends 5mm above the highest dimension of the radiator. After these components are fabricated, they are welded or threaded onto the radiator body, completing the fabrication of the automatic full-water maintenance radiator.

[0042] Example 5 An automatic full-water maintenance type steel radiator includes several single pieces 1 connected together; several single pieces 1 near the water inlet are provided with horizontal diversion plates 5, which are located at the lower part of the corresponding single piece 1; the lower part of the middle single piece 1 is provided with a vertical guide plate 4; the lower part of the inner wall of the two outermost single pieces 1 are provided with pressure control valves 3, which are connected to the water inlet or the water outlet.

[0043] like Figure 5The diagram shows a built-in intelligent example of the present invention. "Built-in" means that the core components are located inside the radiator, specifically a pressure control valve 3 on each of the lower left and right sides of the radiator. When heating is stopped, the actuator of the pressure control valve 3 activates under the action of a pressure sensing signal, closing the valve. This prevents water from being discharged from the radiator's internal cavity, thus achieving full-water maintenance. A vertical guide plate 4, designed as a sheet-like blind plate, is welded to the middle of the lower part of the radiator. Several horizontal diversion plates 5 are provided in the left water inlet area, each with a different number of water flow holes to adjust the diversion effect, ensuring uniform hot water flow throughout the radiator and improving heat dissipation efficiency. Specifically, in manufacturing, for example, φ2.0mm holes are drilled, and sheet-like diversion plates are manufactured according to the designed distribution and quantity gradient. These plates are then welded to corresponding positions on different individual plates according to design requirements to achieve uniform hot water flow. After these components are manufactured, they are welded or threaded onto the radiator body, completing the production of the automatic full-water maintenance radiator.

[0044] Example 6 An automatic full-water maintenance type steel radiator includes several single pieces 1 connected together; several single pieces 1 near the water inlet are provided with horizontal diversion plates 5, which are located at the lower part of the corresponding single piece 1; the lower part of the middle single piece 1 is provided with a vertical guide plate 4; the lower part of the outermost two single pieces 1 are provided with pressure control valves 3, which are connected to the water inlet or the water outlet.

[0045] like Figure 6 The diagram shows an example of the external intelligent type of this invention. "External" means that the core components are located outside the radiator; specifically, a pressure control valve 3 is designed on each of the left and right sides of the lower part of the radiator. When heating is stopped, the actuator of the pressure control valve 3 is activated by a pressure sensing signal, closing the valve. This prevents water from being discharged from the radiator's inner cavity, thus achieving full-water maintenance. A vertical guide plate 4, designed as a sheet-like blind plate, is welded to the middle of the lower part of the radiator. Several horizontal diversion plates 5 are provided in the left water inlet area, each with a different number of water flow holes to adjust the diversion effect, ensuring uniform hot water flow throughout the radiator and improving heat dissipation efficiency. Specifically, in manufacturing, for example, φ2.0mm holes are drilled, and sheet-like diversion plates are manufactured according to the designed distribution and quantity gradient. These plates are then welded to corresponding positions on different individual plates according to design requirements to achieve uniform hot water flow. After the above components are manufactured, they are welded or threaded onto the radiator body, completing the production of the automatic full-water maintenance radiator.

[0046] The automatic full-water maintenance of this invention achieves full-water maintenance by controlling the hot water flow path through internal (external) structural design of the radiator. Any practice that controls the hot water flow circulation path to achieve full-water maintenance by changing the internal (external) structure of the radiator, whether it is a pipe, plate or other similar structure, thereby enhancing corrosion resistance and extending the product life of the radiator, will fall within the scope of protection of this invention.
