Description

Technical Field

[0001] This utility model relates to the field of heat exchanger pipe connection technology, and in particular to a pipe connection structure for a vacuum heat pipe heat exchanger. Background Technology

[0002] Vacuum heat pipe heat exchangers are widely used in various fields such as chemical engineering, pharmaceuticals, and food processing due to their high heat transfer efficiency and excellent energy-saving effects. Their core technology lies in utilizing the phase change heat transfer principle of heat pipes to achieve efficient heat exchange in a vacuum environment. However, the performance of a vacuum heat pipe heat exchanger depends not only on the design and materials of its internal heat pipes, but also on the design of its pipe connection structure. In practical applications, as the requirements for equipment performance and operational safety continue to increase, the design of pipe connection structures is also constantly evolving. The emergence of new flexible and rapid connection technologies can effectively reduce stress concentration caused by thermal expansion and vibration, improving equipment reliability. At the same time, advancements in sealing technology provide better protection for maintaining the vacuum environment.

[0003] However, currently, the connection between such pipes is generally achieved by directly welding bare pipes or by connecting flanges and then covering the outer layer with insulation material. This method involves a large volume of insulation material covering, is complicated to operate, and is inconvenient to install and remove, which is not conducive to subsequent maintenance and replacement. Therefore, there is an urgent need for a pipe connection structure for vacuum heat pipe heat exchangers. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a pipe connection structure for a vacuum heat pipe heat exchanger.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A vacuum heat pipe heat exchanger pipe connection structure includes a mounting base with an inner cavity. A cover plate is bolted to the front side of the mounting base near the inner cavity. A connection mechanism is provided inside the inner cavity. The output end of the connection mechanism is fixedly connected to a fastening half-ring one and a fastening half-ring two. Pipe one and pipe two are snapped into the inside of the fastening half-ring one and the fastening half-ring two, and the connection points of pipe one and pipe two are connected to each other.

[0007] As a further embodiment of this utility model: a mounting ring is bonded to the middle inner wall of the inner cavity, and an adjustment knob is connected to the tail end of the mounting ring by a thread. The outer circumference of the adjustment knob is threaded, and a fixing nut is connected to the circumference of the adjustment knob by a thread. A gasket is bonded to the side of the mounting base near the fixing nut.

[0008] As a further embodiment of this utility model: the connecting mechanism includes a magnetic half-ring, a T-shaped moving plate, a sliding column, a rotating disk and an arc groove, and the magnetic half-ring is welded to the inner circumference of the fastening half-ring one and the fastening half-ring two, and one end of the two T-shaped moving plates is respectively connected to the ends of the fastening half-ring one and the fastening half-ring two by bolts, and the two ends of the two T-shaped moving plates are T-shaped structures.

[0009] As a further embodiment of this utility model: the two sliding columns are respectively threaded to the outer back wall of the two T-shaped moving plates, and the outer back wall of the rotating disk is rotatably connected to the mounting ring through a connecting shaft.

[0010] As a further improvement of this utility model: the end of the connecting shaft is connected to one end of the adjusting knob, and two arc-shaped grooves are formed on the front of the rotating disk.

[0011] As a further improvement of this utility model: the two arc-shaped grooves are centrally symmetrical, and the sliding column and the arc-shaped grooves form a sliding fit.

[0012] As a further improvement of this utility model: guide grooves are respectively provided on the outer walls of both sides of the inner cavity, and the guide grooves form a sliding fit with the end of the T-shaped moving plate.

[0013] Compared with the prior art, this utility model provides a pipe connection structure for a vacuum heat pipe heat exchanger, which has the following advantages:

[0014] 1. This vacuum heat pipe heat exchanger pipe connection structure, by rotating the adjustment knob, drives the connecting shaft at its end to rotate, and the rotating connecting shaft drives the rotating disk to rotate. The rotating disk drives the sliding column to slide in the arc groove. At the same time, the moving sliding column drives the T-shaped moving plate connected to it to move vertically and horizontally in the guide groove. The two T-shaped moving plates move in opposite directions. As a result, the fastening half-ring one and fastening half-ring two at one end of the two T-shaped moving plates complete the clamping action. At the connection point of pipe one and pipe two, while the inner sides of fastening half-ring one and fastening half-ring two are mated, the magnetic half-rings inside fastening half-ring one and fastening half-ring two attract the ends of the two pipes, effectively promoting the connection and fixation between pipe one and pipe two. At the same time, it also solves the drawbacks of traditional vacuum heat pipe heat exchanger pipe connections, and facilitates the installation, removal and replacement of vacuum heat pipe heat exchanger pipes.

[0015] 2. This vacuum heat pipe heat exchanger pipe connection structure, by setting a fixing nut and a washer, ensures that the adjusting knob is limited when rotated at a certain angle, thereby promoting the clamping effect of the fastening half ring one and fastening half ring two on the pipe connection.

[0016] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0025] A pipe connection structure for a vacuum heat pipe heat exchanger, such as Figure 1 , Figure 2 , Figure 3and Figure 4 As shown, the device includes a mounting base 4, which has an inner cavity 17. A cover plate 5 is bolted to the front side of the mounting base 4 near the inner cavity 17. A connecting mechanism 2 is provided inside the inner cavity 17. The output end of the connecting mechanism 2 is fixedly connected to a fastening half ring 1 9 and a fastening half ring 2 10. Pipe 1 1 and pipe 2 3 are snapped into the inside of the fastening half ring 1 9 and the fastening half ring 2 10. The connection points of pipe 1 1 and pipe 2 3 are connected to each other.

[0026] An installation ring 16 is bonded to the middle inner wall of the inner cavity 17, and an adjustment knob 6 is threaded to the tail end of the installation ring 16. The outer circumference of the adjustment knob 6 is threaded, and a fixing nut 7 is threaded to the circumference of the adjustment knob 6. A gasket 8 is bonded to the side of the mounting base 4 near the fixing nut 7.

[0027] To facilitate the connection of pipes in vacuum heat pipe heat exchangers, such as Figure 1 , Figure 2 , Figure 3 As shown, the connecting mechanism 2 includes a magnetic half-ring 11, a T-shaped moving plate 12, a sliding column 13, a rotating disk 14, and an arc groove 15. The magnetic half-ring 11 is welded to the inner circumference of the fastening half-ring 9 and the fastening half-ring 10. One end of the two T-shaped moving plates 12 is respectively connected to the ends of the fastening half-ring 9 and the fastening half-ring 10 by bolts. The two ends of the two T-shaped moving plates 12 are T-shaped structures.

[0028] The two sliding columns 13 are respectively threaded to the outer back wall of the two T-shaped moving plates 12, and the outer back wall of the rotating disk 14 is rotatably connected to the mounting ring 16 through a connecting shaft, and the end of the connecting shaft is connected to one end of the adjusting knob 6. Two arc-shaped grooves 15 are opened on the front of the rotating disk 14, and the two arc-shaped grooves 15 are centrally symmetrical. The sliding columns 13 and the arc-shaped grooves 15 form a sliding fit.

[0029] The outer walls on both sides of the inner cavity 17 are respectively provided with guide grooves 18, and the guide grooves 18 and the ends of the T-shaped moving plate 12 are in sliding fit.

[0030] During operation, rotating the adjustment knob 6 drives the connecting shaft at its end to rotate, which in turn drives the rotating disk 14 to rotate. The rotating disk 14 drives the sliding column 13 to slide within the arc-shaped groove 15. Simultaneously, the moving sliding column 13 drives the connected T-shaped moving plate 12 to move vertically and horizontally within the guide groove 18. The two T-shaped moving plates 12 move in opposite directions, thereby causing the fastening half-ring 9 and fastening half-ring 10 at one end of the two T-shaped moving plates 12 to complete the clamping action. At the connection point of pipe 1 and pipe 2 3, while the connection is made inside the fastening half-ring 9 and fastening half-ring 10, the magnetic half-ring 11 inside the fastening half-ring 9 and fastening half-ring 10 attracts the ends of the two pipes, effectively promoting the connection and fixation between pipe 1 and pipe 2 3. At the same time, it also solves the drawbacks of traditional vacuum heat pipe heat exchanger pipe connection, making it convenient for the installation, removal and replacement of vacuum heat pipe heat exchanger pipes.

[0031] 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.
