Description

Technical Field

[0001] The utility model relates to the technical field of heat exchange coils, and more specifically, to a modular heat exchange coil. Background Art

[0002] Heat exchange coils are typically installed inside equipment such as cooling towers, heat exchangers, and air-cooled heat pumps. Their primary function is to exchange heat with the media flowing into them. Heat exchange coils achieve this by increasing their diameter and contacting the external environment. When high-temperature media passes through the heat exchange coil, the coil exchanges heat with the external environment through various branch pipe loops, thereby reducing the internal temperature.

[0003] After long-term operation, existing heat exchange coils develop severe internal scaling, resulting in low heat exchange efficiency. While dosing devices can be installed to reduce or minimize scaling, the accumulation of scaling is unavoidable. To enhance heat exchange efficiency within the same equipment volume, conventional methods include reducing the tube diameter and increasing coil density. While this improves efficiency, the smaller the diameter of the heat exchange coil, the more susceptible it is to scaling, significantly shortening its service life. Maintenance often requires disassembling the equipment to remove the internal coils for high-pressure pulse cleaning. However, the complex disassembly process makes it difficult to accurately locate blockages. Furthermore, frequent disassembly during routine maintenance inevitably compromises system stability and creates hidden risks. Systematic cleaning is performed only infrequently, but scaling is severe and cannot be completely eliminated. Over time, equipment performance deteriorates and system failures become increasingly frequent, necessitating replacement of the coils or equipment.

[0004] Now there is a need for a detachable modular heat exchange coil that can accurately locate blockage points and is easy to clean and descale to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a modular heat exchange coil to overcome the above-mentioned defects in the prior art.

[0007] As a preferred embodiment, the spliced ​​heat exchange coil unit is composed of a first heat exchange coil outer tube assembly, n heat exchange coil inner tube assemblies, and a second heat exchange coil outer tube assembly, which are spliced ​​and connected in sequence. One end of the first heat exchange coil outer tube assembly is detachably connected to a water outlet branch of the water inlet module, and one end of the second heat exchange coil outer tube assembly is detachably connected to a water inlet branch of the water outlet module, and n is an integer greater than or equal to 1.

[0009] As a preferred embodiment, both ends of the first heat exchange coil outer tube assembly, the n heat exchange coil inner tube assemblies and the second heat exchange coil outer tube assembly are fixed with splicing blocks, and the splicing blocks can be spliced ​​with each other.

[0010] As a preferred embodiment, the magnetic ball detection device includes a magnetic ball inlet assembly, a magnetic ball outlet assembly and a magnetic ball, the magnetic ball inlet assembly is fixedly connected above a water outlet branch of the water inlet module, and the magnetic ball outlet assembly is fixedly connected below a water inlet branch of the water outlet module.

[0012] By adopting the above technical solution, the utility model has the following beneficial effects:

[0013] (1) The utility model provides a detachable spliced ​​fixed module pipeline. After the equipment has been running for a long time, each coil can be disassembled to flush out scale and other impurities inside each branch pipe. By setting up a magnetic ball detection, when the energy efficiency of the equipment is reduced, the magnetic ball can be placed in the detection entrance, and the specific blockage position of the coil can be determined by the flow of the magnetic ball. At the same time, magnetic balls of different sizes can clean and descale the inner wall of the pipe under the action of water flow, reduce scaling, and extend the service life of the equipment.

When a separate pipeline is damaged, the separate pipeline can be disassembled separately, which is convenient for repair and replacement, and greatly reduces labor and material costs. At the same time, the processing and production of long pipelines is more complicated than that of separate pipelines, and the production cost is higher, but the production, installation, and operation and maintenance costs of spliced ​​fixed modular pipelines are lower.

[0029] (Example 1)

[0030] See Figure 1A modular heat exchange coil includes an inlet module 1, a heat exchange coil module, and an outlet module 3. The inlet module 1 is specifically a water distributor with an inlet pipe and eight outlet branches. The outlet module 3 is specifically a water collector with eight inlet branches and one outlet pipe. The heat exchange coil module is composed of eight spliced ​​heat exchange coil units 2. One end of each spliced ​​heat exchange coil unit 2 is connected to an outlet branch of the inlet module 1 and the other end is connected to an inlet branch of the outlet module 3. Each spliced ​​heat exchange coil unit 2 is equipped with a magnetic ball detection device 4. The inlet module 1 is located below the heat exchange coil module, and the outlet module 3 is located within the heat exchange coil module. Cooling water flows from bottom to top.

[0031] See Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The spliced ​​heat exchange coil unit 2 is composed of a first heat exchange coil outer tube assembly 2-1, at least one heat exchange coil inner tube assembly 2-2, and a second heat exchange coil outer tube assembly 2-3, which are spliced ​​and connected in sequence. One end of the first heat exchange coil outer tube assembly 2-1 is detachably connected to a water outlet branch of the water inlet module 1, and one end of the second heat exchange coil outer tube assembly 2-3 is detachably connected to a water inlet branch of the water outlet module 3.

[0032] The connecting pipe openings of the first heat exchange coil outer tube assembly 2-1, the heat exchange coil inner tube assembly 2-2, and the second heat exchange coil outer tube assembly 2-3 are all provided with threads, and the first heat exchange coil outer tube assembly 2-1, the heat exchange coil inner tube assembly 2-2, and the second heat exchange coil outer tube assembly 2-3 are sequentially connected through a bidirectional threaded pipe 2-5;

[0033] Each section of the first heat exchange coil outer tube assembly 2-1, the heat exchange coil inner tube assembly 2-2, and the second heat exchange coil outer tube assembly 2-3 has splicing blocks 2-4 at both ends. The splicing blocks 2-4 can be spliced ​​and connected, and the number of heat exchange coil inner tube assemblies 2-2 can be adjusted according to different heat exchange efficiency requirements. The more heat exchange coil inner tube assemblies 2-2 there are, the better the heat exchange efficiency.

[0034] See Figure 1 and Figure 5 The magnetic ball detection device 4 includes a magnetic ball inlet component 4-1, a magnetic ball outlet component 4-2 and a magnetic ball 4-3. The magnetic ball inlet component 4-1 is fixedly connected above a water outlet branch of the water inlet module 1, and the magnetic ball outlet component 4-2 is fixedly connected below a water inlet branch of the water outlet module 3.

[0035] Magnetic ball inlet assembly 4-1 includes a handwheel 4-1-1, a rotating rod 4-1-2, and a first connecting pipe 4-1-3. The handwheel 4-1-1 is fixed to one end of the rotating rod 4-1-2, and the other end is provided with a groove that mates with the magnetic ball 4-3. The rotating rod 4-1-2 is rotatably connected to one end of the first connecting pipe 4-1-3, and the other end of the first connecting pipe 4-1-3 is connected to a water outlet branch of the water inlet module 1. The magnetic ball outlet assembly 4-2 uses the same structure as the magnetic ball inlet assembly 4-1, but with a filter installed at the corresponding position on the water inlet branch of the water outlet module 3. When the magnetic ball flows through the filter, it can roll into the magnetic ball outlet assembly 4-2, and the magnetic ball can be easily removed by turning the handwheel.

[0036] The working principle of this embodiment is as follows:

[0037] When the circulating cooling water enters the water inlet, it flows through the manifold into the corresponding branch pipes and then into the heat exchange coil module. In the heat exchange coil module, the internal circulating cooling water flows from bottom to top, fully exchanges heat with the external medium, and then flows into the manifold from the top manifold branch pipe, finally flowing out of the outlet.

[0038] When the heat exchange coil's energy efficiency decreases, place a magnetic ball in the groove of the rotating rod and turn the handwheel to drive the rotating rod. The magnetic ball in the rotating rod groove then enters the branch pipe. Under the force of gravity and water pressure, the magnetic ball enters the corresponding spliced ​​heat exchange coil unit and rolls within the pipe with the water flow.

[0039] When the magnetic ball cannot pass through the severely scaled area inside the spliced ​​heat exchange coil unit, the magnetic ball can be accurately located by using a corresponding magnetic metal object outside the heat exchange coil unit, and the spliced ​​heat exchange coil unit at that location can be removed for cleaning or replacement.

[0040] When there is no scale on the inner wall of the spliced ​​heat exchange coil unit, the magnetic ball rolls smoothly around the tube and is blocked by the filter at the magnetic ball detection port. Under the pressure of water flow and gravity, it falls into the groove of the rotating rod and is finally taken out by turning the handwheel.

[0041] At the same time, by placing magnetic balls of different sizes, the rolling of the magnetic balls in the spliced ​​heat exchange coil unit can also clean the inside of the heat exchange coil and extend its service life.

[0042] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
