Abstract

This invention discloses an ice storage coil and its assembly / disassembly method, comprising a frame, with two identical manifolds fixed at one end of the frame. Several detachable serpentine coils are arranged sequentially from top to bottom within the frame. The serpentine coils are sheet-like, with both the beginning and end points located on one side of the manifold. One manifold has an inlet A and an outlet B on one side wall, and the other manifold has an outlet A and an inlet B on one side wall. Several connection ports C and D are provided on the other side walls of both manifolds. The serpentine coils are flanged to the connection ports C or D on the manifolds. In this invention, the manifolds contain a spacer tube, creating two paths with different flow directions. The heat exchange medium in adjacent serpentine coils flows in opposite directions, thus balancing the beginning and end points of adjacent serpentine coils, resulting in more uniform heat exchange within the ice storage tank where the ice storage coil is located, and improving the overall heat exchange efficiency.

Description

Technical Field

[0001] This invention relates to the field of chemical waste gas treatment equipment, and in particular to an ice storage coil and its disassembly and assembly method. Background Technology

[0002] With the rapid development of my country's economy, the widespread use of air conditioners has not only increased the capacity of urban power grids but also exacerbated the imbalance between peak and off-peak power supply. As an important energy utilization technology, ice storage technology has seen significant development in recent years.

[0003] As the core component of an ice storage system, the ice storage coil stores the cooling energy produced by the ice maker at night in the form of ice. During the day, when the air conditioner needs cooling, the ice is melted to provide the required cooling. Therefore, the performance of the ice storage coil largely determines the energy efficiency ratio of the ice storage air conditioning system and its reliable operation. The main factors affecting the performance of the ice storage coil are the structure and layout of the internal heat exchange tubes. Existing ice storage coils are mostly arranged using a "serpentine coil-fixture-serpentine coil" method to fix the coils to the support. However, the ice storage coils frequently alternate between hot and cold temperatures, making them prone to failure. When arranging the serpentine coils in the above manner, if one serpentine coil breaks, multiple serpentine coils and fixtures need to be disassembled and removed to replace the broken serpentine coil, which is very cumbersome. In addition, the heat exchange medium in existing ice storage coils flows from one end to the other, resulting in a large temperature difference between the beginning and end of the heat exchange medium. The heat exchange effect at the end is not ideal, and the overall heat exchange is uneven, affecting the overall efficiency of the ice storage tank. This is an existing problem. Summary of the Invention

[0004] To overcome the shortcomings of the existing technology, the present invention provides an ice storage coil and its disassembly and assembly method, wherein the heat exchange medium in adjacent serpentine coils flows in opposite directions, resulting in more uniform overall heat exchange and improved heat exchange efficiency, thereby improving the existing problems.

[0005] This invention is achieved through the following technical solution:

[0006] An ice storage coil includes a frame with two identical manifolds fixed to one end. Several detachable serpentine coils are arranged sequentially from top to bottom within the frame. Each serpentine coil is sheet-shaped, with its first and last ends located on one side of a manifold. One manifold has an A inlet and a B outlet on one side wall, while the other manifold has an A outlet and a B inlet on one side wall. Several C and D connection ports are located on the other side wall of both manifolds. A spacer pipe is installed within each manifold. The A inlet and A outlet are connected to the C connection ports, and the B inlet and B outlet are connected to the D connection ports via the spacer pipe. The A inlet, A outlet, B inlet, and B outlet on each manifold are connected to an external circulation pipe. The serpentine coils are flange-connected to either the C or D connection ports on the manifolds, with the flow directions within the C and D connection ports being opposite.

[0007] In a further optimized manner, the C-connection port and D-connection port on the side wall of the water collector are arranged alternately.

[0008] Further optimized, the first and last ends of the serpentine coil are connected to the C or D connection ports flanges on the two manifolds, and the flow directions in adjacent serpentine coils are opposite.

[0009] Furthermore, the spacer tube is covered with a heat insulation layer.

[0010] Further optimized, the frame body is provided with a support frame, and the support frame has several through holes.

[0011] Further optimized, a groove is formed inside the through hole, and the diameter of the groove is equal to the outer diameter of the serpentine coil.

[0012] Further optimized, the serpentine coil is provided with a first limiting post and a second limiting post at both ends. The first limiting post is fixed on the frame and located at the end close to the water distribution unit, while the second limiting post is detachably mounted on the frame and located at the far end of the water distribution unit.

[0013] Further optimized, the first and second limiting posts are provided with several limiting grooves.

[0014] In a further optimized manner, firstly, remove the second limiting post from the frame, then insert the serpentine coil into the support frame through the through hole in sequence. Connect the first and last ends of the serpentine coil to the C or D connection port flange on the manifold. Then, install the second limiting post on the frame, using the limiting groove on the limiting post to limit and support the serpentine coil. When the serpentine coil is damaged and needs to be disassembled, remove the second limiting post, disassemble and replace the damaged serpentine coil separately, and then reinstall the second limiting post.

[0015] The beneficial effects of this invention are:

[0016] In this invention, the water manifold is equipped with a partition tube, which makes the water manifold contain two paths with different flow directions. The heat exchange medium in the adjacent serpentine coils flows in opposite directions, thereby making the head and tail of the adjacent serpentine coils cooperate with each other, making the heat exchange more balanced, making the heat exchange in the ice storage tank where the ice storage coil is located more uniform, and improving the overall heat exchange efficiency.

[0017] In this invention, each serpentine coil can be disassembled and replaced individually, making maintenance more convenient. Attached Figure Description

[0025] To clearly illustrate the technical features of this solution, the invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings. In the description of this invention, it should be noted that the terms "left," "right," "front," "rear," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention.

[0026] like Figures 1-6As shown, the present invention provides an ice storage coil, including a frame 1. Two identical water collectors 2 are fixed at one end of the frame 1 by a fixing plate 11. Several detachable serpentine coils 3 are arranged sequentially from top to bottom inside the frame 1. The serpentine coils 3 are sheet-shaped, and the first and last ends of the serpentine coils 3 are located on one side of the water collectors 2.

[0027] One of the water distribution units has an A inlet 23 and a B outlet 21 on one side wall, and another water distribution unit has an A outlet 24 and a B inlet 22 on one side wall. Both water distribution units 2 have a number of C connection ports 26 and D connection ports 27 on their other side walls, wherein the C connection ports 26 and D connection ports 27 are spaced apart from each other.

[0028] The manifold 2 is equipped with a partition pipe 25. The A inlet 23 and A outlet 24 are both connected to the C connection port 26. The B inlet 22 and B outlet 21 are both connected to the D connection port 27 through the partition pipe 25. Then, the serpentine coil 3 is connected to the C connection port 26 or the D connection port 27 flange on the manifold 2. The flow direction in the C connection port and the D connection port is opposite, and the heat exchange medium in the adjacent serpentine coil 3 flows in the opposite direction. This allows the heat exchange between adjacent serpentine coils to cooperate with each other, making the heat exchange more balanced, and making the heat exchange in the ice storage tank where the ice storage coil is located more uniform, thereby improving the overall heat exchange efficiency.

[0029] In a preferred embodiment, the A inlet 23, A outlet 24, B inlet 22 and B outlet 21 on the water manifold are connected to an external circulation pipeline, which is connected to a chiller or cooling tower for supplying ethylene glycol or other heat exchange media.

[0030] In a preferred embodiment, the C or D connection ports on the first and last ends of the serpentine coil 3 and the two manifolds 2 create two circulations within the entire ice storage coil, with the flow directions in adjacent serpentine coils 3 being opposite. Furthermore, the spacer tube 25 is covered with an insulation layer, or the spacer tube is made of an insulating material, to prevent the two flowing heat exchange media from interfering with each other within the manifolds and affecting heat exchange efficiency.

[0031] In a preferred embodiment, the frame 1 is provided with a support frame 4, which has several through holes 41. Each through hole 41 has a groove 42, the diameter of which is equal to the outer diameter of the serpentine coil. During installation, the through holes 41 facilitate the passage of the serpentine coil, while the grooves 42 support and limit its movement.

[0032] In a preferred embodiment, the two ends of the serpentine coil 3 are provided with a first limiting post 6 and a second limiting post 5. The first limiting post 6 is fixed on the frame 1 and located at one end close to the water collector 2. The second limiting post 5 is detachably mounted on the frame 1 and located at the far end of the water collector. Furthermore, a plurality of limiting grooves 51 are provided on the first limiting post 6 and the second limiting post 5.

[0033] like Figure 3 , 5 As shown in Figure 6, the water manifold of this invention is equipped with a partition tube, which makes the water manifold contain two paths with different flow directions. The heat exchange medium in the adjacent serpentine coils flows in opposite directions, thereby making the head and tail of the adjacent serpentine coils cooperate with each other, making the heat exchange more balanced, making the heat exchange in the ice storage tank where the ice storage coil is located more uniform, and improving the overall heat exchange efficiency.

[0034] Example 2:

[0035] A method for disassembling and assembling an ice storage coil: First, remove the second limiting post 5 from the frame. Then, insert the serpentine coil 6 into the support frame 4 through the through hole. Secure the corner of the serpentine coil 3 into the limiting groove 51 of the first limiting post 6. Next, connect the first and last ends of the serpentine coil to the flange of the C connection port 26 or D connection port 27 on the water manifold. Then, install the second limiting post 5 on the frame 1. The limiting groove on the limiting post limits and supports the serpentine coil.

[0036] When the serpentine coil 2 is damaged and needs to be disassembled, remove the second limiting post 5, disassemble and replace the damaged serpentine coil separately, and then reinstall the second limiting post. This makes disassembly and maintenance more convenient.

Finally, it should be noted that the above embodiments are merely illustrative of the technical solutions of this invention and not intended to limit it. Although the invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this invention without departing from the spirit and scope of the invention, and all such modifications and substitutions should be covered within the scope of the claims of this invention.
