Description

Technical Field

[0001] This utility model relates to a cooling coil and a heat dissipation device for a feed tube. Background Technology

[0002] A separate-inlet reactor is a specially designed reaction device. Its core feature is the introduction of different reactants or gases into the reaction zone through independent inlet channels, enabling more precise reaction control. The reactor is equipped with multiple inlets, each with individually controllable gas flow rate, pressure, and temperature. When introducing flammable or explosive gases, excessively high inlet temperatures can lead to deflagration or even explosion; therefore, inlet cooling is necessary. Currently, cooling jackets or spiral cooling pipes are commonly used to cool the inlets, reducing safety hazards. Spiral cooling pipes, in particular, are more widely used due to their ease of installation and modifiability.

[0003] However, due to the structural limitations of existing cooling pipes, their heat dissipation effect is not satisfactory, and improvements all have different drawbacks. For example, improving heat dissipation efficiency is limited by the length of the inlet pipe; and adding external heat dissipation components will increase equipment and production costs.

[0004] Therefore, how to adjust the structure of the cooling pipe to improve heat dissipation efficiency while limiting cost is the technical problem that this application aims to solve. Utility Model Content

[0005] One of the main objectives of this utility model is to overcome at least one of the above-mentioned defects and to provide a cooling coil and material tube heat dissipation device that can effectively reduce the surface temperature of the material tube, has low investment cost, and is easy to upgrade and modify later.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] This utility model provides a cooling coil for cooling a feed tube, comprising a first winding portion, a connecting portion, and a second winding portion, wherein...

[0008] The first end of the first winding part is a liquid inlet, the tail end of the first winding part is connected to the first end of the second winding part through the connecting part, and the tail end of the second winding part is a liquid outlet.

[0009] The first winding part is cylindrical in shape and is attached to the outer wall of the material tube;

[0010] The second coiled portion is spirally coiled along the radial direction of the first coiled portion, with the first end of the second coiled portion located on the outermost side.

[0011] According to one embodiment of the present invention, the second winding part is in the form of a planar Archimedean spiral and is formed by continuous bending of the tube, with all the pipes arranged in a loop on the same plane.

[0012] According to one embodiment of the present invention, the outer walls of adjacent pipes of the second coil section are fixedly connected to form a whole by adhesive or auxiliary fixing mechanism.

[0013] According to one embodiment of the present invention, the first end of the second coiled portion is located at the end of the outer edge of the spiral.

[0014] According to one embodiment of the present invention, the second winding part adopts a single-layer winding structure, and the pipelines are arranged at equal intervals.

[0015] According to one embodiment of the present invention, it further includes multiple fixing mechanisms, each fixing mechanism including two fixing plates and a nut. The two fixing plates are arranged radially along the second winding portion and are respectively arranged on the upper and lower sides of the second winding portion. The ends of the two fixing plates are fixedly connected by the nut.

[0016] According to one embodiment of the present invention, at least one of the two fixing plates has a plurality of slots on its outer surface, and heat dissipation fins are inserted into each slot.

[0017] According to one embodiment of the present invention, each slot is filled with thermally conductive adhesive.

[0018] According to one embodiment of the present invention, a cavity is left between the inner edge of the second winding portion and the outer wall of the first winding portion, and a plurality of feed branch pipes are inserted in the cavity.

[0019] In particular, this application also provides a heat dissipation device for a feed tube, which includes a circulation pump and a cooling coil as described above, wherein the circulation pump drives the refrigerant to circulate in the cooling coil.

[0020] Compared with the prior art, the advantages and beneficial effects of the cooling coil and material pipe heat dissipation device of this utility model patent application are as follows:

[0021] The cooling coil of this application exchanges heat with the surface of the feed tube through the first coiled part, and then achieves heat exchange and dissipation with the air through the second coiled part. In particular, the first end of the second coiled part is located at the outer edge (away from the feed tube), which allows the heat energy of the feed tube to be quickly discharged. The heat-conducting liquid with a higher temperature is sent from the tail end of the first coiled part to the outer edge of the second coiled part. This heat loss distribution makes the cooling more efficient and can improve the heat dissipation efficiency of the feed tube.

[0022] Furthermore, the cooling coil structure of this application is simple, and the first winding part and the second winding part can be processed separately to achieve modular design and manufacturing. When assembled to the material pipe or the area to be cooled, the two are connected and welded together through the connecting part, which is easy to manufacture and install, reduces equipment cost and production cost, and also facilitates subsequent upgrades or modifications as needed.

[0023] In addition, the optimized fixing mechanism can improve the overall strength of the cooling coil, and fins can be added to the surface of the fixing plate of the fixing mechanism to further improve the heat dissipation effect, and also provide possibilities for subsequent upgrades or modifications.

[0039] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0040] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0041] Example 1:

[0042] This embodiment describes a cooling coil for cooling a feed tube, such as... Figure 1 As shown, it includes a first winding part 1, a connecting part 3, and a second winding part 2. The first winding part 1 has a liquid inlet 11 at its beginning (which can be connected to the output port of an external circulation pump), and the first winding part 12 is connected to the first winding part 21 of the second winding part 2 through the connecting part 3. The second winding part 2 has a liquid outlet 22 at its end (which can be connected to the input port of an external circulation pump). The first winding part 1 is cylindrical in shape and is attached to the outer wall of the material pipe 6. The second winding part 2 is spirally wound along the radial direction of the first winding part 1, and the first winding part 21 of the second winding part 2 is located on the outermost side.

[0043] The second coiled section 2 has a planar Archimedean spiral configuration and is formed by continuous bending of the tube. It adopts a single-layer coiled structure with each tube arranged at equal intervals. All tubes are arranged in a loop on the same plane. The outer walls of adjacent tubes in the second coiled section are fixedly connected to form a whole by adhesive or auxiliary fixing mechanism. The first end 21 of the second coiled section 2 is located at the outer edge end of the spiral.

[0044] It is understood that in this embodiment, the cooling coil has its first coiled portion 1 in contact with the outer wall of the feed tube 6 to conduct heat. Heat is exchanged through the surface contact between the first coiled portion 1 and the feed tube 6. The coolant flows and circulates between the first coiled portion 1 and the second coiled portion 2, achieving heat exchange and dissipation with the air through the second coiled portion 2. In particular, the beginning end 21 of the second coiled portion 2 is located at the outer edge (away from the feed tube 6), allowing the heat energy of the feed tube 6 to be quickly dissipated. Furthermore, the higher-temperature heat-conducting liquid is sent from the tail end 12 of the first coiled portion 1 to the outer edge of the second coiled portion 2. This heat dissipation distribution makes cooling more efficient, improving the heat dissipation efficiency of the feed tube 6. The first coiled portion 1 and the second coiled portion 2 can be processed separately, achieving modular design and manufacturing. When assembled into the feed tube 6 or the area requiring cooling, the two are connected and welded together via the connecting portion 3, facilitating manufacturing and installation, reducing equipment and production costs, and allowing for subsequent upgrades or modifications as needed.

[0045] Generally speaking, such as Figure 2 As shown, the feed pipe 6 is connected to the reaction vessel or equipment via the flange 61 head. The second coiled part 2 can be adapted to the size of the flange 61, so as not to occupy the space of the feed pipe 6 excessively. Compared with the existing technology, it can effectively utilize the equipment space and save the site area.

[0046] Example 2:

[0047] This embodiment describes a cooling coil, whose main structure is basically the same as that of Embodiment 1, except that it also includes multiple fixing mechanisms 4. Each fixing mechanism 4 includes two fixing plates 41 and a nut 42. The two fixing plates 41 are arranged radially along the second winding portion 2 and are respectively disposed on the upper and lower sides of the second winding portion 2. The ends of the two fixing plates 41 are fixedly connected by the nuts 42. This fixing structure design can improve the overall strength of the cooling coil and enhance its operational stability and reliability.

[0048] Example 3:

[0049] Based on Embodiment 2, this embodiment can further optimize the heat dissipation function. Specifically, one or two fixing plates 41 of the fixing mechanism 4 have several slots 411 on their outer surfaces, and heat dissipation fins 5 are inserted into each slot 411.

[0050] Specifically, in this embodiment, a slot 411 is opened on the outer surface of the upper fixing plate 41 of one of the fixing mechanisms 4, and a heat dissipation fin 5 is inserted into the slot 411.

[0051] Additionally, if there is a gap between the fin 5 and the slot 411 of the fixing plate 41 (due to processing errors or thermal expansion and contraction), air will become a bottleneck in thermal resistance. Thermally conductive adhesive can be filled into each slot 411. This adhesive can be silicone grease, thermally conductive pads, or epoxy resin. Filling the gap between the slot 411 and the fin 5 with thermally conductive adhesive effectively reduces contact thermal resistance and improves the fixing effect and thermal conductivity of the fin 5 within the slot 411.

[0052] Example 4:

[0053] This embodiment describes a cooling coil, whose main structure is basically the same as that of Embodiment 1. The difference is that it not only cools the main feed pipe 6, but also allows the feed branch pipe 7 to enter between the first winding part 1 and the second winding part 2, and simultaneously cools the feed branch pipe 7.

[0054] Specifically, such as Figure 6 As shown, a cavity is left between the inner edge of the second winding part 2 and the outer wall of the first winding part 1, and a plurality of feed branch pipes 7 are inserted into the cavity. The feed branch pipes 7 can be supplied with a gas different from that in the feed pipe 6 (to avoid the gas in the feed branch pipe 7 from coming into contact with and reacting with the gas in the feed pipe 6). Due to the presence of the two winding parts, the temperature in this cavity can be effectively cooled by the feed branch pipes 7. The feed branch pipes 7 can be supplied with a gas at a higher temperature than that in the feed pipe 6 or a flammable or explosive gas.

[0055] Example 5:

[0056] This embodiment describes a heat dissipation device for a feed tube 6, which includes a circulation pump and a cooling coil as described in Embodiment 1. The circulation pump drives the refrigerant to circulate in the cooling coil to achieve cooling of the feed tube 6.

[0057] Due to the special structure of the cooling coil in the aforementioned embodiment, effective cooling of the material tube 6 can be achieved. Only an external circulating pump to drive the flow of cooling liquid is needed, which can effectively reduce the cost compared to traditional equipment.

[0058] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
