Description

Technical Field

[0001] The utility model relates to the technical field of heat pipe assembly, in particular to an assembly device for radial heat pipes. Background Art

[0002] The radial heat pipe consists of spiral fins, an outer sleeve, an inner tube, a sealing plug and a vacuum (exhaust) joint on the outer sleeve. The radial heat pipe is usually arranged horizontally, and the outer sleeve and the inner tube are coaxial or eccentric. The liquid medium is injected into the closed cavity between the outer sleeve and the inner tube and evacuated. During operation, the medium in the closed cavity repeatedly switches between liquid and gas and exchanges heat with the medium in the inner tube. It is required that the medium in the closed cavity must not contact the inner tube when it is liquid, so the relative position of the outer sleeve and the inner tube is strictly required. There are two existing assembly processes:

[0003] 1. Manually use a tape measure or positioning block to position the outer sleeve and inner core tube at both ends of the heat pipe. This method has a large error, and each radial heat pipe needs to be measured and positioned at least twice. It is inefficient and difficult to ensure assembly quality.

[0004] 2. The outer sleeve and the inner core tube are positioned by using an assembly device to achieve coaxial or eccentric installation. However, the existing assembly device is only applicable to radial heat pipes of the same specification. Different assembly devices are required to install radial heat pipes of different specifications, and the same assembly device can only achieve coaxial installation or eccentric installation. As a result, the existing assembly device has poor adaptability. Multiple assembly devices are required to assemble radial heat pipes of different specifications and different assembly methods, which increases production costs and subsequent maintenance costs.

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an assembly device for radial heat pipes. By arranging a support bar that can move up and down, inner core pipes of different specifications can be supported and moved, which is not only convenient for adjusting the coaxial or eccentric setting between the inner core pipe and the outer sleeve, but also convenient for the device to limit the position of radial heat pipes of different specifications and different installation methods, thereby improving the adaptability of the device.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] Preferably, two second support plates are arranged in parallel on one side of the workbench, and an angle positioning device is movably arranged between the two second support plates.

[0009] Preferably, the angle positioning device includes a rotating shaft, and two parallel second support plates are each provided with an arc groove compatible with the second bayonet, the rotating shaft is arranged in the arc groove of the two parallel second support plates, and an arc plate is arranged on the rotating shaft, and the arc plate is located between the two parallel second support plates, the arc top of the arc plate is fixedly connected to the rotating shaft, and a nut is threadedly installed on the end of the rotating shaft, and a limiting block is provided at the other end of the rotating shaft, and the nut can abut against the second support plate when rotating.

[0010] Preferably, an indicator mark is provided on the turning handle, and a scale is provided on the workbench at the bottom of the screw.

[0011] Preferably, the bottoms of the first bayonet and the second bayonet are both arc-shaped structures, and shock-absorbing pads are provided on the first bayonet and the second bayonet.

[0012] Preferably, the support plate and the support bar are both provided with arc-shaped notches for placing radial heat pipes, and shock-absorbing pads are provided at the arc-shaped notches.

[0013] Preferably, the bottom end of the first bayonet and the bottom end of the second bayonet are at the same level.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model has a simple structure. The handles at both ends of the first support plate are manually rotated at the same time. The two handles are rotated at the same time to drive the screw to drive the supporting bar to move up and down horizontally. Since the two ends of the inner core tube are located in the first buckle, when the supporting bar moves up and down horizontally, the inner core tube can be driven to move up and down in the outer sleeve until it reaches a suitable position (ensuring that the inner core tube is coaxial or eccentric with the outer sleeve). By abutting the sealing plugs arranged at both ends of the inner core tube with the end faces of the outer sleeve and the inner core tube, it is convenient for the operator to weld the sealing plugs to the inner core tube and the outer sleeve, so that a closed cavity is formed between the inner core tube and the outer sleeve.

[0016] 2. The sizes of the first and second bayonet holes of the device are compatible with the sizes of the maximum specifications of the radial heat pipes. Therefore, when assembling radial heat pipes with small specifications, the inner core tube and the outer sleeve can be located at the top of the arc structure at the bottom of the first and second bayonet holes under their own weight, which is convenient for limiting radial heat pipes of different specifications. The two ends and the middle part of the outer sleeve can be supported by the support plate to prevent the outer sleeve from bending downward in the middle part due to its own weight. The inner core tubes of different specifications can be supported and moved by the adjustable support strip, which is convenient for adjusting the positional relationship between the inner core tube and the outer sleeve. The device can limit the positions of radial heat pipes of different specifications and different installation methods, which is convenient for operators to assemble, thereby improving the adaptability of the device.

[0017] 3. The shock-absorbing pads provided at the first and second bayonet ports of the device are convenient for protecting the device and the radial heat pipe, avoiding collision between the device and the radial heat pipe, which would affect the assembly efficiency, and ensuring the service life of the device.

[0018] 4. The arc-shaped notch of the device can limit the spiral fins on the outside of the inner core tube and the outer sleeve to prevent them from sliding during installation, which would affect the installation efficiency; the provided shock-absorbing pad can protect both the radial heat pipe and the device at the same time, to prevent the radial heat pipe and the device from having a large collision when the radial heat pipe is placed on the device, thereby ensuring the service life of the device and preventing the radial heat pipe from being damaged by collision.

[0019] 5. The bottom ends of the first and second bayonet ports of the device are at the same horizontal height. When adjusting the position between the inner core tube and the outer sleeve, it is convenient for the support bar to drive the inner tube to move upward from the bottom of the inner wall of the outer sleeve to adjust the position, thereby increasing the adjustment range of the support bar of the device on the inner core tube.

[0020] 6. The device is also provided with an angle positioning device, so that when the eccentric setting is completed, the arc plate is driven to rotate at an angle between two adjacent second support plates by rotating the rotating shaft in the arc groove, ensuring that the end of the arc plate abuts against the vacuum (exhaust) joint welded to the end of the outer sleeve, and the rotating shaft continues to be rotated to push the vacuum (exhaust) joint to a required angle through the arc plate. When the outer sleeve rotates, the inner core tube can still maintain the eccentric setting with the outer sleeve. When the vacuum (exhaust) joint is rotated to a required angle, a nut is threadedly installed on the end of the rotating shaft to limit the screw. When the nut rotates, it can cooperate with the limit block to limit the rotating shaft to the two second support plates, and the arc plate abuts against the vacuum (exhaust) joint to limit the angle of the vacuum (exhaust) joint, thereby further improving the adaptability of the device.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Embodiment 1

[0028] An assembly device for radial heat pipes, the structure of which is as follows Figure 1-Figure 4As shown, it includes a workbench 1, and the four corners of the bottom of the workbench 1 are provided with supporting legs 2. The workbench 1 is a square frame structure. A horizontal plate 3 is provided in the middle of the workbench 1, and a motor 4 is provided in the middle of the horizontal plate 3. A connecting plate 5 moving toward the top of the workbench 1 is installed at the power output end of the motor 4, and a supporting plate 6 is provided in the middle and both ends of the connecting plate 5. Second supporting plates 8 are provided at both ends of the workbench 1, and first supporting plates 7 are provided on the sides of the two second supporting plates 8 away from the motor 4. The first supporting plate 7 and the second supporting plate 8 are respectively provided with a first bayonet 12 and a second bayonet 11 adapted to the radial heat pipe, and the first supporting plate 7 has a cavity connected to the first bayonet 12 inside, and a supporting bar 15 is provided in the cavity, and threaded holes are provided at both ends of the supporting bar 15, and screws 14 are installed in the threaded holes. The bottom of the screw 14 is connected to the workbench 1 through a rotating shaft 17, and a turning handle 16 is provided on the top of the screw 14. The bottoms of the first bayonet 12 and the second bayonet 11 are both arc-shaped structures, and shock-absorbing pads are disposed on the first bayonet 12 and the second bayonet 11 .

[0029] When assembling the radial heat pipe, first place the outer sleeve with the spiral fins on the support plate 6, the spiral fins abut against the support plate 6, and drive the outer sleeve on the connecting plate 5 to move up and down through the power output end of the motor 4, ensuring that the two ends of the outer sleeve are respectively located at the bottom of the second bayonet 11 of the two second support plates 8, and the two ends of the inner core tube inserted in the outer sleeve are located in the first bayonet 12 of the two first support plates 7;

[0030] According to the installation requirements, the handles 16 at both ends of the first support plate 7 are manually rotated at the same time. The two handles 16 rotate simultaneously to drive the screw 14 to drive the supporting bar 15 to move horizontally up and down. Since the two ends of the inner core tube are located in the first buckle, when the supporting bar 15 moves horizontally up and down, it can drive the inner core tube to move up and down in the outer sleeve until it reaches a suitable position (ensuring that the inner core tube is coaxial or eccentric with the outer sleeve). By abutting the sealing plugs arranged at both ends of the inner core tube with the end faces of the outer sleeve and the inner core tube, it is convenient for the operator to weld the sealing plugs to the inner core tube and the outer sleeve, so that a closed cavity is formed between the inner core tube and the outer sleeve.

[0031] Since the sizes of the first bayonet 12 and the second bayonet 11 are compatible with the sizes of the maximum specifications of the radial heat pipe, when assembling radial heat pipes with small specifications, the inner core tube and the outer sleeve can be located at the top of the arc structure at the bottom of the first bayonet 12 and the second bayonet 11 under their own weight, which is convenient for limiting radial heat pipes of different specifications. The supporting plate 6 can support the two ends and the middle part of the outer sleeve to prevent the outer sleeve from bending downward in the middle part due to its own weight. The adjustable supporting strip 15 can support and move the inner core tubes of different specifications, which is convenient for adjusting the positional relationship between the inner core tube and the outer sleeve. This makes it convenient for the device to limit the position of radial heat pipes of different specifications and different installation methods, and is convenient for operators to assemble them, thereby improving the adaptability of the device.

[0032] The shock-absorbing pads provided at the first bayonet 12 and the second bayonet 11 are convenient for protecting the device and the radial heat pipe, avoiding collision between the device and the radial heat pipe, which would affect the assembly efficiency, and ensuring the service life of the device.

[0033] The turning handle 16 is provided with an indication mark, and the workbench 1 at the bottom of the screw rod 14 is provided with a scale.

[0034] When it is necessary to adjust the support bar 15 to drive the inner core tube to move up and down, the handles 16 at both ends of the same first support plate 7 are turned at the same time. When the handle 16 is rotated, the indicator mark on its upper end cooperates with the scale on the workbench 1, so as to accurately adjust the moving position of the support bar 15, which is convenient for operators to install radial heat pipes of different specifications or different installation methods.

[0035] The supporting plate 6 and the supporting bar 15 are both provided with arc-shaped notches for placing radial heat pipes, and shock-absorbing pads are provided at the arc-shaped notches.

[0036] The arc-shaped notch can limit the spiral fins on the outside of the inner core tube and the outer sleeve to prevent them from sliding during installation, which would affect the installation efficiency; the provided shock-absorbing pad can protect both the radial heat pipe and the device at the same time to prevent the radial heat pipe and the device from causing large collisions when the radial heat pipe is placed on the device, thereby ensuring the service life of the device and preventing the radial heat pipe from being damaged by collisions.

[0037] The bottom end of the first bayonet 12 and the bottom end of the second bayonet 11 are at the same level.

[0038] Since the bottom end of the first bayonet 12 and the bottom end of the second bayonet 11 are at the same horizontal height, when adjusting the position between the inner core tube and the outer sleeve, it is convenient for the support bar 15 to drive the inner tube to move upward from the bottom of the inner wall of the outer sleeve to adjust the position, thereby increasing the adjustment range of the inner core tube by the support bar 15 of the device.

[0039] Embodiment 2

[0040] On the basis of the first embodiment, two second support plates 8 are arranged in parallel on one side of the workbench 1, and an angle positioning device is movably arranged between the two second support plates 8. The angle positioning device comprises a rotating shaft 9, and arc grooves matching the second bayonet 11 are arranged on the two second support plates 8 arranged in parallel, and the rotating shaft 9 is arranged in the arc grooves of the two second support plates 8 arranged in parallel, and an arc plate 10 is arranged on the rotating shaft 9, and the arc plate 10 is located between the two second support plates 8 arranged in parallel, and the arc top of the arc plate 10 is fixedly connected to the rotating shaft 9, and a nut 13 is installed at the end of the rotating shaft 9 by thread, and a limit block is arranged at the other end of the rotating shaft 9, and the nut 13 can abut against the second support plate 8 when rotating.

[0041] The installation method of some radial heat pipes is relatively unique. It is necessary to adjust the position between the inner core tube and the outer sleeve to make the inner core tube and the outer sleeve eccentrically set. It is also necessary to ensure that the vacuum (exhaust) joint installed at the end of the outer sleeve is installed tilted during the eccentric setting. By setting an angle positioning device, it is convenient to rotate the arc plate 10 between the two adjacent second support plates 8 by rotating the rotating shaft 9 in the arc groove when the eccentric setting is completed, ensuring that the end of the arc plate 10 is in contact with the vacuum (exhaust) joint welded to the end of the outer sleeve, and continue to rotate. The shaft 9 pushes the vacuum (exhaust) joint to the required angle through the arc plate 10. When the outer sleeve rotates, the inner core tube can still maintain the eccentric setting with the outer sleeve. When the vacuum (exhaust) joint is rotated to the required angle, since the end of the rotating shaft 9 is threadedly installed with a nut 13, the screw 14 is limited. When the nut 13 rotates, it can cooperate with the limit block to limit the rotating shaft 9 on the two second support plates 8. The arc plate 10 abuts against the vacuum (exhaust) joint to limit the angle of the vacuum (exhaust) joint, thereby further improving the adaptability of the device.

[0042] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or additions, subtractions or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
