Abstract
Description
Technical Field
[0001] This utility model relates to the field of cold storage technology, specifically to a high-efficiency thermally conductive aluminum pipe structure for the roof of a cold storage facility. Background Technology
[0002] Cold storage piping is an essential component of cold storage facilities. Currently, existing aluminum cold storage piping systems typically come with matching mounting brackets. The aluminum piping is first welded to the brackets, and then the brackets are hoisted to the ceiling of the cold storage. This installation method is extremely cumbersome, and if the piping is damaged, the entire assembly needs to be disassembled and replaced, significantly increasing future maintenance costs. Furthermore, existing aluminum piping systems rely on the coolant inside the pipes directly exchanging heat with the outside air through the pipe walls to generate cold air. However, the limited contact area between the coolant and the pipe wall restricts heat exchange efficiency, resulting in low refrigeration efficiency. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a high-efficiency heat-conducting aluminum pipe structure for the top of a cold storage, which can replace individual straight or bent pipes during use and has a higher heat exchange efficiency.
[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:
[0005] A high-efficiency thermally conductive aluminum pipe system for the roof of a cold storage facility, comprising:
[0006] Straight pipes, bent pipes, and splicing structures; multiple straight pipes are arranged parallel to each other in the left-right direction, and each straight pipe is connected in series by a bent pipe. The straight pipes and bent pipes are detachably connected by a splicing structure, and the connection is sealed. Heat-conducting fins are formed on the outer wall of the straight pipes, which are evenly arranged in the circumferential direction.
[0007] The hanging frame is used to install and fix all the splicing structures on the same side to the same hanging frame.
[0008] As an improvement, the bottom ends of each heat-conducting fin located on the lower side of the straight pipe are fixedly connected to the same guide groove. The cross-section of the guide groove is an arc structure, and after both ends are closed, a water outlet is provided at one end. This can effectively guide the water formed on the outer wall of the straight pipe.
[0009] As an improvement, the splicing structure includes:
[0010] The adapter pipe has end rings formed on the outer walls of both ends of the straight pipe and the bend pipe, and an adapter pipe is sandwiched between the opposite end rings. The adapter pipe is an externally threaded pipe body and has the same diameter as the straight pipe and the bend pipe.
[0011] The nut cap is used in a curved pipe structure where straight pipe sections are formed at both ends. The nut cap, when closed at one end, forms a through hole for the straight or curved pipe section. The nut cap is movably fitted onto both ends of the straight or curved pipe, and then threaded onto the outer wall of the adapter pipe. This allows for easy splicing or disassembly of the straight and curved pipes, facilitating individual replacement of either the straight or curved pipe.
[0012] As an improvement, the hanging frame includes a hanging rod and a strip mounting plate; a hanging rod is formed on the upper middle part of the connecting pipe, and the top of the hanging rod on the same side is fixedly connected to the same strip mounting plate, with mounting holes reserved at both ends of the strip mounting plate. This allows the new hanging frame to be securely installed on the ceiling of the cold storage room.
[0013] The advantages of this utility model compared with the prior art are as follows:
[0014] 1. This new type consists of straight pipes, splicing structures, and bends. After the new type is installed on the top of the cold storage by hanging the hanger, the straight pipes or bends can be disassembled and replaced individually, effectively solving the problem that "if the pipes are damaged, the whole set needs to be disassembled and replaced".
[0015] 2. This novel straight pipe has multiple heat-conducting fins on its outer wall, which increases the contact area between the straight pipe and the air, thereby improving its refrigeration efficiency for cold storage. The guide grooves also provide some heat conduction and effectively drain water that forms on the outer wall of the straight pipe to the outside of the cold storage. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.
[0023] A high-efficiency thermally conductive aluminum pipe system for the roof of a cold storage facility, comprising:
[0024] The system comprises a straight pipe 1, a bent pipe 2, and a splicing structure. Five straight pipes 1 are arranged parallel to each other in the left-right direction. Each straight pipe 1 is connected in series via bent pipes 2, and the straight pipes 1 and bent pipes 2 are detachably connected via a splicing structure. The splicing structure includes: a transition pipe 6, where end rings 7 are formed on the outer walls of both ends of the straight pipe 1 and the bent pipe 2, and a transition pipe 6 is sandwiched between the opposing end rings 7. The transition pipe 6 is an externally threaded pipe body with the same diameter as the straight pipe 1 and the bent pipe 2; and a nut cap 8, where the bent pipe 2 is an arc-shaped pipe with straight pipe sections formed at both ends. The nut cap 8 is closed at one end, with the closed end forming a through hole that perfectly fits the straight pipe section of the straight pipe 1 or the bent pipe 2. The nut cap 8 is movably fitted onto both ends of the straight pipe 1 and the bent pipe 2, and then threaded onto the outer wall of the transition pipe 6.
[0025] A heat-conducting fin 3 is formed on the outer wall of the straight pipe 1 and is evenly arranged in the circumferential direction. The bottom end of each heat-conducting fin 3 located on the lower side of the straight pipe 1 is fixedly connected to the same flow guide 4. The cross section of the flow guide 4 is an arc structure, and after both ends are closed, an outlet 5 is provided at one end. The flow guide 4 is a metal copper structure, the same as the heat-conducting fin 3.
[0026] The hanging frame includes a hanging rod 9 and a strip mounting plate 10; the middle upper side of the connecting pipe 6 forms a hanging rod 9, and the top of the hanging rod 9 on the same side is fixedly connected to the same strip mounting plate 10, and the two ends of the strip mounting plate 10 are respectively reserved with mounting holes.
[0027] In the specific implementation of this embodiment:
[0028] like Figure 1 and 2 As shown, after using bolts to install and fix the strip mounting plate 10 to the inner top wall of the cold storage, the free ends of the two straight pipes 1 are connected to other components of the refrigeration system (a cold storage-specific refrigeration system well known to those skilled in the art), and a water hose is connected to the water outlet 5 to divert water to the outside of the cold storage. This completes the hanging installation of this invention. Then, this invention can be used to refrigerate the cold storage.
[0029] Then loosen the nut cap 8 and screw it onto the straight pipe section that exists only on the straight pipe 1 or the bend pipe 2. The straight pipe 1 and the bend pipe 2 can then be disconnected, and then they can be disassembled and replaced.
[0030] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
