Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and in particular to an energy-saving floating coil heat exchanger. Background Technology

[0002] A floating coil heat exchanger is an indirect heat exchanger. The heat transfer section uses copper tubes, which are spirally arranged and float within the shell, hence the name "floating coil." Floating coil heat exchangers have become a typical piece of equipment in domestic centralized hot water heating systems in recent years.

[0003] Existing floating coil heat exchangers, during use, exhibit irregular floating and swaying, failing to achieve orderly and cyclical up-and-down floating under controlled conditions. This prevents damage to the coils caused by inconsistent floating distances and potential leaks. Furthermore, during the floating heat exchange process inside the casing, dirt and scale accumulate on the coil surface. Failure to clean the coil surface reduces heat exchange efficiency, resulting in higher energy consumption and overall inefficiency.

[0004] Therefore, we propose an energy-saving floating coil heat exchanger. Utility Model Content

Therefore, this invention proposes an energy-saving floating coil heat exchanger.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] Design an energy-saving floating coil heat exchanger, including a shell with a cover plate installed at the top. A coil is installed inside the shell, and a rotating brush mechanism is installed on the outside of the coil. Water inlet and outlet ends on both sides of the coil are connected to water guide pipes, and upper and lower floating mechanisms are connected to the outside of the water guide pipes.

The rotating bar is fixedly connected to the bottom ends of both ends of the connecting plate and is located on both sides of the coil. The brush bar is connected to the inside of the rotating bar.

[0009] Furthermore, the rack is slidably mounted on the top of the cover plate, and the rack has snap-fit ​​grooves on its upper and lower sides. A snap-fit ​​frame is fixed to the top of the cover plate. The snap-fit ​​frame has a C-shaped structure, and its open end is slidably snapped into the inside of the snap-fit ​​groove. An electric push rod is horizontally mounted on the top of the cover plate, and the telescopic end of the electric push rod is fixedly connected to one end of the rack.

[0010] Furthermore, a limiting ring is fixed in the middle of the surface of the water guide pipe, and the bottom end of the limiting ring is connected to the top end of the spring. A limiting plate is horizontally fixed on the inner surface of the outer shell, and a limiting hole is opened on the surface of the limiting plate. The water guide pipe slides through the limiting hole, and the top end of the limiting plate is connected to the bottom end of the spring.

[0011] Furthermore, a rotating rod is rotatably passed through the side of the outer casing, and a motor is installed at the outer end of the rotating rod. The motor is installed on the outside of the outer casing, the cam plate is fixed to the surface of the rotating rod, and the bottom end of the push plate has an abutment groove. The top end of the cam plate slides into the abutment groove.

[0012] Furthermore, a bolt connects the top edge of the cover plate to the top edge of the outer shell, a water inlet pipe is connected to the top edge of one side of the outer shell, a water outlet pipe is connected to the bottom edge of the other side of the outer shell, a support leg is fixed to the bottom edge of the outer shell, a base plate is installed at the bottom of the outer shell, and a drain pipe is connected to the middle of the bottom edge of the base plate.

[0013] Furthermore, the inlet and outlet pipes of the coil are both connected to flange connectors. One side of the water guide pipe is detachably connected to the inlet and outlet pipes of the coil via the flange connector. The bottom end of one water guide pipe and the top end of the other water guide pipe are both connected to a telescopic hose. The bottom end of one telescopic hose is connected to a refrigerant inlet pipe, and the top end of the other telescopic hose is connected to a refrigerant outlet pipe. The refrigerant inlet pipe passes tightly through the base plate, and the refrigerant outlet pipe passes tightly through the cover plate.

[0014] Furthermore, the outer shell is a cylindrical structure and is vertically arranged; the coil is a spiral structure and is vertically arranged; the water guide pipe is vertically arranged; the gear and the rack are both horizontally arranged; the rotating bar is a long rectangular structure and is vertically arranged; the brush bar is horizontally arranged, and its extended end contacts the surface of the coil; the connecting plate is horizontally arranged above the coil and is spaced apart at the bottom end of the cover plate.

[0016] The energy-saving floating coil heat exchanger proposed in this utility model has the following advantages:

[0017] 1. This utility model installs a coil inside the outer casing and connects two water guide pipes to the inlet and outlet ends of the coil via flange connectors. The water guide pipes are slidably installed between the coil and the outer casing via limiting rings, springs, and limiting plates, maintaining only vertical elastic movement. A push plate is fixed at the bottom of the water guide pipes, and a cam plate is positioned at the bottom of the push plate via a rotating rod. Thus, after the two water guide pipes are connected to the refrigerant inlet and outlet pipes via flexible hoses, during heat exchange inside the outer casing, the motor drives the rotating rod to rotate, which in turn pushes the push plate via the cam plate. This causes the water guide pipes to move up and down through the limiting holes on the limiting plate surface. The springs provide cushioning and springiness, thus keeping the coil horizontally limited inside the outer casing and maintaining a regular, orderly up-and-down floating motion, preventing damage to the coil due to fluctuating floating distances.

[0018] 2. In this invention, a brush strip is connected to the side of the coil via a rotating strip. The rotating strip is connected to a gear via a connecting plate and a rotating column. The gear is mounted on the top of the cover plate and meshes with the rack. Therefore, during heat exchange inside the coil, the electric push rod drives the rack to move back and forth within the snap-fit ​​frame, and through meshing, drives the gear to rotate back and forth half a revolution. This, in turn, causes the rotating strip and brush strip to rotate back and forth half a revolution on both the inner and outer sides of the coil via the rotating column and connecting plate. This effectively cleans the surface of the coil, removing dirt and scale, keeping the coil surface clean, facilitating heat conduction, and preventing the accumulation of dirt and scale that reduces heat exchange efficiency. This allows the coil to perform heat exchange in a more energy-efficient and effective manner. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] For examples, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The figure shows an energy-saving floating coil heat exchanger, including a shell 1, a cover plate 2 installed on the top of the shell 1, a coil 26 installed inside the shell 1, a rotating brushing mechanism installed on the outside of the coil 26, and water guide pipes 21 connected to the inlet and outlet ends on both sides of the coil 26. The upper and lower floating mechanism is connected to the outside of the water guide pipes 21.

[0028] The rotating brushing mechanism includes a driving mechanism and a brushing mechanism; the driving mechanism includes a gear 4 and a rack 5, the gear 4 is rotatably mounted on the top of the cover plate 2, and the gear 4 and the rack 5 are meshed and connected for transmission.

[0029] The rack 5 is slidably installed on the top of the cover plate 2. The rack 5 has snap-fit ​​grooves 15 on its upper and lower sides. The top of the cover plate 2 is fixed with a snap-fit ​​frame 6. The snap-fit ​​frame 6 has a C-shaped structure and its open end is slidably snapped into the inside of the snap-fit ​​groove 15. An electric push rod 8 is horizontally installed on the top of the cover plate 2. The telescopic end of the electric push rod 8 is fixedly connected to one end of the rack 5.

[0030] The outer shell 1 is a cylindrical structure and is vertically arranged; the coil 26 is a spiral structure and is vertically arranged; the water guide pipe 21 is vertically arranged; and the gear 4 and the rack 5 are both horizontally arranged.

[0031] The brushing mechanism includes a rotating bar 16 and a brushing bar 17. A rotating column 19 is fixed in the middle of the gear 4. A connecting plate 18 is fixed at the bottom end of the rotating column 19. The rotating bar 16 is fixedly connected to the bottom ends of both ends of the connecting plate 18 and is located on both sides of the coil 26. The brushing bar 17 is connected to the inner side of the rotating bar 16.

[0032] During the heat exchange process inside the outer casing 1, the electric push rod 8 drives the rack 5 to move back and forth in the snap-fit ​​frame 6, and through the meshing transmission connection, drives the gear 4 to rotate back and forth half a revolution. This, in turn, drives the rotating column 19 and the connecting plate 18 to rotate the rotating bar 16 and the brush bar 17 back and forth half a revolution on the inner and outer sides of the coil 26. Combined with the up and down floating of the coil 26 inside the outer casing 1, the surface of the coil 26 can be brushed and cleaned of the adhering dirt and scale, keeping the surface of the coil 26 clean, which is conducive to heat conduction and avoids the reduction of heat exchange efficiency due to the adhesion of dirt and scale. This allows the coil 26 to perform heat exchange in a relatively energy-efficient and efficient manner.

[0033] The rotating bar 16 is a long rectangular structure and is vertically arranged. The brush bar 17 is horizontally arranged, and its extended end contacts the surface of the coil 26. The connecting plate 18 is horizontally arranged above the coil 26 and is spaced apart at the bottom end of the cover plate 2.

A limiting plate 24 is fixed horizontally on the inner surface of the outer shell 1. A limiting hole 32 is opened on the surface of the limiting plate 24. The water guide pipe 21 slides through the limiting hole 32. The top end of the limiting plate 24 is connected to the bottom end of the spring 25.

[0036] The jacking mechanism includes a cam plate 28, and a jacking plate 27 is fixed to the bottom surface of the water guide pipe 21. The top end of the cam plate 28 and the bottom end of the jacking plate 27 are in abutting connection.

[0037] A rotating rod 29 is rotatably passed through the side of the outer casing 1. A motor 30 is installed at the outer end of the rotating rod 29. The motor 30 is installed on the outside of the outer casing 1. The cam plate 28 is fixed to the surface of the rotating rod 29. The bottom end of the push plate 27 has an abutment groove 31. The top end of the cam plate 28 is slidably inserted into the abutment groove 31.

[0038] After the two water pipes 21 are connected to the refrigerant inlet pipe 11 and the refrigerant outlet pipe 7 through the telescopic hose 20, during the heat exchange process inside the outer shell 1, the motor 30 drives the rotating rod 29 to rotate, and through the cam plate 28, it cyclically pushes the actuating plate 27, thereby driving the water pipes 21 to move up and down in the limiting hole 32 on the surface of the limiting plate 24. The spring 25 provides buffering and bounce, thereby keeping the coil 26 in the horizontal direction within the outer shell 1 and maintaining a regular up and down floating pattern, avoiding damage to the coil 26 due to sudden changes in the floating distance.

[0039] The cam plate 28 is vertically arranged, the push plate 27 is horizontally arranged, and the rotating rod 29 is horizontally arranged below the coil 26.

[0040] A bolt 3 connects the top edge of the cover plate 2 to the top edge of the outer shell 1. A water inlet pipe 9 is connected to the top edge of one side of the outer shell 1, and a water outlet pipe 10 is connected to the bottom edge of the other side of the outer shell 1. A support leg 13 is fixed to the bottom edge of the outer shell 1, and a base plate 14 is installed at the bottom of the outer shell 1. A sewage pipe 12 is connected to the middle of the bottom edge of the base plate 14.

[0041] The inlet and outlet pipes of the coil 26 are both connected to flange connectors 22. One side of the water guide pipe 21 is detachably connected to the inlet and outlet pipes of the coil 26 through the flange connectors 22. The bottom end of one water guide pipe 21 and the top end of the other water guide pipe 21 are both connected to a telescopic hose 20. The bottom end of one telescopic hose 20 is connected to a refrigerant inlet pipe 11, and the top end of the other telescopic hose 20 is connected to a refrigerant outlet pipe 7. The refrigerant inlet pipe 11 passes tightly through the base plate 14, and the refrigerant outlet pipe 7 passes tightly through the cover plate 2.

[0042] Working method: A coil 26 is installed inside the outer casing 1, and two water guide pipes 21 are installed at the inlet and outlet ends of the coil 26 through a flange connector 22. The water guide pipes 21 are limited and slidably installed between the outer casing 1 and the limiting ring 23, spring 25 and limiting plate 24, maintaining only vertical elastic movement. At the same time, a top plate 27 is fixed at the bottom end of the water guide pipe 21, and a cam plate 28 is set at the bottom end of the top plate 27 through a rotating rod 29.

[0043] Thus, after the two water pipes 21 are connected to the refrigerant inlet pipe 11 and the refrigerant outlet pipe 7 through the telescopic hose 20, during the heat exchange process inside the outer shell 1, the motor 30 drives the rotating rod 29 to rotate, and through the cam plate 28, it cyclically pushes the actuating plate 27, thereby driving the water pipes 21 to move up and down in the limiting hole 32 on the surface of the limiting plate 24. The spring 25 provides buffering and bounce, thereby keeping the coil 26 horizontally limited inside the outer shell 1 and maintaining a regular up and down floating pattern, avoiding damage to the coil 26 due to sudden changes in the floating distance.

[0044] The brush strip 17 is connected to the side of the coil 26 via a rotating strip 16, and the rotating strip 16 is connected to the gear 4 via a connecting plate 18 and a rotating column 19. Meanwhile, the gear 4 is installed on the top of the cover plate 2 and meshes with the rack 5 for transmission.

[0045] Therefore, during the heat exchange process inside the outer casing 1, the electric push rod 8 drives the rack 5 to move back and forth in the snap-fit ​​frame 6, and through the meshing transmission connection, drives the gear 4 to rotate back and forth half a revolution. This, in turn, drives the rotating column 19 and the connecting plate 18 to rotate the rotating bar 16 and the brush bar 17 back and forth half a revolution on both the inner and outer sides of the coil 26. Combined with the up and down floating of the coil 26 inside the outer casing 1, the surface of the coil 26 can be brushed and cleaned of the adhering dirt and scale, keeping the surface of the coil 26 clean, which is conducive to heat conduction and avoids the reduction of heat exchange efficiency due to the adhesion of dirt and scale. This allows the coil 26 to perform heat exchange in a relatively energy-efficient and efficient manner.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
