Description

Technical Field

[0001] The invention relates to the technical field of refrigeration plate welding and fixing, in particular to a multi-stage semiconductor refrigeration plate welding fixture. Background Art

[0002] A cooling sheet, also known as a thermoelectric semiconductor cooling element or Peltier, is a cooling device that works based on the Peltier effect. This device achieves cooling through the heat transfer phenomenon generated when current flows between N-type semiconductors and P-type semiconductors. The cooling sheet is usually composed of many N-type and P-type semiconductor particles arranged one above the other. These particles are connected by copper, aluminum or other metal conductors to form a complete circuit. In order to protect and fix these semiconductor particles, the outside of the cooling sheet is usually sandwiched by two insulating and thermally conductive ceramic sheets. This structure is similar to a sandwich cookie.

[0003] However, the refrigeration sheet in the prior art still has the following defects when used:

[0004] 1. In the application scenario of multi-stage clamping of refrigeration plates, the clamping method is adopted that only the two ends of the refrigeration plate are pressurized inward to achieve clamping. Since the clamping force is mainly concentrated at the two ends of the refrigeration plate, this may cause the stress generated by the internal clamping to be concentrated inside the refrigeration plate. Under long-term action, the refrigeration plate may be damaged by cracks, fractures and other phenomena, affecting the refrigeration performance and safety of use. If the clamping force at both ends is too small, it is easy to loosen or move, which may cause the refrigeration plate to fail to fully fill the welding gap during welding, forming a weak weld, and even defects such as cold welding and incomplete welding may occur. This will not only reduce the strength of the welded joint, but may also cause leakage in the refrigeration system during use, affecting the overall performance of the system.

[0005] 2. Existing cooling plates can usually only be clamped and welded for a fixed number of cooling plates, and thus the spacing between these cooling plates cannot be adjusted during welding. This is because the distance between the cooling plates directly affects their heat dissipation effect. Different cooling requirements may require different cooling plate spacings to achieve the best cooling effect. Therefore, the cooling plate clamping method that cannot adjust the spacing limits its applicability in different application scenarios.

[0006] Therefore, a multi-stage semiconductor refrigeration plate welding fixture is proposed to solve the above problems. Summary of the invention

[0007] In view of this, the technical problem to be solved by the present invention is to propose a multi-stage semiconductor refrigeration plate welding fixture to solve the problems of uneven clamping force of the refrigeration plate and poor adaptability of the clamping device in the prior art.

[0009] The clamping and regulating mechanism is used for opening and closing the n-shaped slide plate;

[0010] The uniform squeezing mechanism is used for uniformly clamping the refrigeration sheet.

[0011] Preferably, the clamping and adjustment mechanism includes a first adjusting handle, a threaded shaft is fixedly connected to the first adjusting handle, an n-shaped fixing plate is threadedly connected to the outer surface of the threaded shaft, both ends of the n-shaped fixing plate are fixedly connected to the support plate, and a turntable is fixedly connected to one end of the threaded shaft away from the first adjusting handle.

[0012] Preferably, the middle portion of the turntable is rotatably connected to the support plate, and a swing arm is rotatably connected to a side of the turntable close to the threaded shaft, and the swing arm is symmetrically arranged on the turntable.

[0013] Preferably, the swing arm is rotatably connected to one end away from the turntable with a connecting plate, the outer surfaces of both ends of the connecting plate penetrate the support plate, and the two ends of the connecting plate are fixedly connected to the n-shaped slide plate.

[0014] Preferably, the uniform extrusion mechanism includes a second adjusting handle, a transmission wheel is fixedly connected to the middle part of the second adjusting handle, a transmission belt is transmission-connected to the transmission wheel, a multi-functional baffle is fixedly connected to the side of the support plate close to the transmission wheel, a vertical slide groove is opened in the middle part of the multi-functional baffle, a slider is slidably connected in the vertical slide groove of the multi-functional baffle, a compression spring is fixedly connected to the slider, and the compression spring is fixedly connected in the vertical slide groove at one end away from the slider.

[0015] Preferably, the transmission wheel is evenly arranged on the multi-functional baffle, and the transmission wheel is rotatably connected to the slider near the middle of the multi-functional baffle. The transmission wheels at both ends of the multi-functional baffle are fixedly connected with threaded transmission rods. Sliding holes are opened at both ends of the multi-functional baffle, and the outer surface of the threaded transmission rod is slidably connected to the sliding holes, and the tooth surfaces at both ends of the threaded transmission rod are meshed in the n-shaped slider.

[0016] Preferably, an arc groove is opened in the middle part of the threaded transmission rod, an extrusion column is slidably connected in the arc groove, an extrusion plate is fixedly connected to one end of the extrusion column away from the arc groove, guide rods are slidably connected to both ends of the extrusion plate, both ends of the guide rod are fixedly connected to an n-shaped slide plate, and the extrusion plates are linearly arranged on the outer surface of the guide rod.

[0017] Preferably, the uniform extrusion mechanism also includes a ball, a sliding block is rotatably connected to the axis of the ball, the outer surfaces of both ends of the extrusion plate are fixedly connected to a slide groove body, the outer surface of the sliding block is slidably connected to the inner wall of the slide groove body, the sliding block is fixedly connected to a buffer spring at one end away from the ball, and the buffer spring is fixedly connected to the slide groove body at one end away from the sliding block.

[0018] Compared with the prior art, the multi-stage semiconductor refrigeration plate welding fixture provided by the present invention has the following beneficial effects:

[0019] 1. The clamping and regulating mechanism can be set to adjust the opening and closing of the n-shaped slide plate so that the groove in the middle of the refrigeration plate can be connected to the extrusion plate. By adjusting the lateral extrusion of the refrigeration plate body, the refrigeration plate body can always be kept in the center position, so that each refrigeration plate can be firmly clamped in a fixed position, reducing the risk of loosening or displacement caused by vibration or external force;

[0020] The present invention proposes an innovative method for clamping and fixing a refrigeration plate. The method retains the traditional clamping method and, by introducing a clamping mechanism that is adjusted jointly by a first adjusting handle and a second adjusting handle, achieves accurate clamping and uniform pressure on each refrigeration plate. By rotating the first adjusting handle and the second adjusting handle, the present invention can ensure that each refrigeration plate is subjected to balanced pressure during the welding process, thereby effectively avoiding the problem of reduced internal quality of the refrigeration plate due to uneven force at both ends and the middle in the traditional clamping method.

[0021] This design improvement not only reduces the potential damage to the refrigeration fins due to differences in extrusion stress, but also significantly improves the welding quality of the entire refrigeration fins. Traditional clamping methods often cause the refrigeration fins at both ends to be damaged due to excessive force, or the middle refrigeration fins to be loosely welded due to insufficient force. The present invention perfectly solves these problems through precise adjustment and uniform pressure, thereby reducing the reduction in internal quality of the refrigeration fins caused by different extrusion forces and further improving the overall welding quality of the refrigeration fins.

[0022] 2. Through the setting of the uniform extrusion mechanism, the clamping distance of each refrigeration plate can be controlled by adjusting the second adjustment handle. By adjusting the clamping distance, not only can the optimal contact area between the refrigeration plate and the heat dissipation device be ensured, thereby reducing thermal resistance and improving heat transfer efficiency, but also the heat generated by the refrigeration plate can be quickly dissipated, the low temperature state of the refrigeration plate can be maintained, and the overall refrigeration effect can be improved.

[0023] 3. Through the uniform extrusion mechanism, different numbers of refrigeration plates can be clamped and fixed separately. When the refrigeration demand changes, there is no need to replace the entire clamping device. Only simple adjustments can be made to achieve the clamping and fixation of the new number of refrigeration plates, which improves the flexibility and response speed of the system. Moreover, by accurately controlling the clamping spacing of each refrigeration plate, it can be ensured that each refrigeration plate can achieve standardized welding, and each refrigeration plate can achieve standardized spacing welding. Not only can it ensure good contact between the refrigeration plate and the heat dissipation device, improve the overall welding quality, and reduce thermal resistance, but also the heat transfer efficiency can be improved through high-precision welding quality, which is conducive to the refrigeration plate after welding to achieve a more uniform heat dissipation effect.

[0024] The present invention can not only achieve good heat conduction between the refrigeration plates by setting a uniform welding spacing, but also, in the refrigeration system, the heat conduction efficiency between the refrigeration plates directly affects the performance of the entire system. By optimizing the welding spacing, the present invention can reduce the thermal resistance caused by uneven spacing, improve the heat conduction efficiency, and thus improve the overall performance of the refrigeration system. In the traditional welding method, it may be necessary to adjust the distance between the refrigeration plates one by one, which is not only time-consuming and labor-intensive, but also prone to errors. The present invention achieves synchronous optimization of the spacing between all refrigeration plates through a one-time adjustment, thereby greatly improving production efficiency.

[0025] In traditional welding methods, due to inaccurate spacing control, some refrigeration plates may be damaged due to uneven heating, or fail due to loose welding. The present invention reduces this risk by improving welding accuracy and consistency, thereby saving costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] The present invention is further described in detail below based on the accompanying drawings and embodiments.

[0040] Example

[0041] Please refer to Figures 1 to 7 As shown:

[0042] In order to solve the problems mentioned in the technical solution, the embodiment of the present application provides a multi-stage semiconductor refrigeration plate welding fixture, including an operating table 1, a support plate 11 is fixedly connected to the upper surface of the operating table 1, an n-shaped slide plate 12 is slidably connected to the support plate 11, a refrigeration plate body 13 is arranged in the middle of the operating table 1, and also includes a clamping and regulating mechanism 2 and a uniform extrusion mechanism 3, the clamping and regulating mechanism 2 is arranged on the side of the support plate 11 away from the n-shaped slide plate 12, and the uniform extrusion mechanism 3 is arranged on the n-shaped slide plate 12;

[0043] The clamping and regulating mechanism 2 is used for opening and closing the n-shaped slide plate 12;

[0044] The uniform squeezing mechanism 3 is used for uniformly clamping the refrigeration sheet 13;

[0045] The clamping and regulating mechanism 2 includes a first regulating handle 21, a threaded shaft 22 is fixedly connected to the first regulating handle 21, an n-shaped fixing plate 23 is threadedly connected to the outer surface of the threaded shaft 22, both ends of the n-shaped fixing plate 23 are fixedly connected to the support plate 11, and a rotating disk 24 is fixedly connected to the end of the threaded shaft 22 away from the first regulating handle 21;

[0046] The middle part of the turntable 24 is rotatably connected to the support plate 11, and the turntable 24 is rotatably connected to a swing arm 25 on one side close to the threaded shaft 22. The swing arm 25 is symmetrically arranged on the turntable 24.

[0047] The swing arm 25 is rotatably connected to one end of the swing plate 24 away from the turntable 24, and the outer surfaces of both ends of the connecting plate 26 penetrate the support plate 11, and both ends of the connecting plate 26 are fixedly connected to the n-shaped slide plate 12;

[0048] Wherein: the n-shaped slide plates 12 are symmetrically arranged on both sides of the refrigeration plate body 13.

[0049] In the prior art, in the application scenario of multi-stage clamping of the refrigeration sheet 13, the clamping is achieved by only applying inward pressure to the two ends of the refrigeration sheet 13. Since the clamping force is mainly concentrated at the two ends of the refrigeration sheet 13, this may cause thermal stress to be concentrated inside the refrigeration sheet 13. Under long-term action, the refrigeration sheet 13 may be damaged by cracks, fractures, etc., affecting the refrigeration performance and safety of use. Compared with the prior art, through the implementation of this embodiment, the opening and closing of the n-shaped slide plate 12 can be adjusted so that the middle groove of the refrigeration sheet 13 can be interconnected with the extrusion plate 37. By adjusting the lateral extrusion of the refrigeration sheet 13, not only can the refrigeration sheet 13 always be kept in the center position, but each refrigeration sheet 13 can also be firmly clamped in a fixed position, reducing the risk of loosening or displacement due to vibration or external force.

[0050] For further examples, please refer to Figures 1 to 7 As shown:

[0051] The uniform extrusion mechanism 3 includes a second adjustment handle 31, a transmission wheel 32 is fixedly connected to the middle of the second adjustment handle 31, a transmission belt 33 is transmission-connected to the transmission wheel 32, a multifunctional baffle 35 is fixedly connected to the side of the support plate 11 close to the transmission wheel 32, a vertical slide groove is provided in the middle of the multifunctional baffle 35, a slider 301 is slidably connected in the vertical slide groove of the multifunctional baffle 35, a compression spring 302 is fixedly connected to the slider 301, and the compression spring 302 is fixedly connected to the vertical slide groove at one end away from the slider 301;

[0052] The transmission wheels 32 are evenly arranged on the multifunctional baffle 35. The transmission wheels 32 are rotatably connected to the slider 301 near the middle of the multifunctional baffle 35. The transmission wheels 32 at both ends of the multifunctional baffle 35 are fixedly connected with threaded transmission rods 34. Sliding holes are opened at both ends of the multifunctional baffle 35. The outer surface of the threaded transmission rod 34 is slidably connected in the sliding holes. The tooth surfaces at both ends of the threaded transmission rod 34 are meshed in the n-shaped slide plate 12.

[0053] An arc groove 36 is provided in the middle of the threaded transmission rod 34, an extrusion column is slidably connected in the arc groove 36, an extrusion plate 37 is fixedly connected to one end of the extrusion column away from the arc groove 36, guide rods 38 are slidably connected to both ends of the extrusion plate 37, both ends of the guide rod 38 are fixedly connected to the n-shaped slide plate 12, and the extrusion plates 37 are linearly arranged on the outer surface of the guide rod 38;

[0054] The uniform extrusion mechanism 3 also includes a ball 41, a sliding block 42 is rotatably connected to the axis of the ball 41, the outer surfaces of both ends of the extrusion plate 37 are fixedly connected to the slide groove body, the outer surface of the sliding block 42 is slidably connected to the inner wall of the slide groove body, the end of the sliding block 42 away from the ball 41 is fixedly connected to the buffer spring 43, and the end of the buffer spring 43 away from the sliding block 42 is fixedly connected to the slide groove body;

[0055] The threaded transmission rod 34 to the guide rod 38 are symmetrically arranged on both sides of the refrigeration plate 13 , and the thickness of the groove in the middle of the refrigeration plate 13 is adapted to the edge of the extrusion plate 37 .

[0056] In the prior art, when the refrigeration fins 13 are clamped, only a fixed number of refrigeration fins 13 can be clamped and welded, so that the spacing between the refrigeration fins 13 cannot be adjusted when welding, because the distance between the refrigeration fins 13 directly affects the heat dissipation effect, and different refrigeration requirements may require different refrigeration fin spacings to achieve the best refrigeration effect. Therefore, the refrigeration fin 13 clamping method that cannot adjust the spacing limits its applicability in different application scenarios. Compared with the prior art, through the implementation of this embodiment, different numbers of refrigeration fins 13 can be clamped and fixed separately. When the refrigeration demand changes, there is no need to replace the entire clamping device. Only a simple adjustment can be made to achieve the clamping and fixing of the new number of refrigeration fins 13, which improves the flexibility and response speed of the system. Moreover, by accurately controlling the clamping spacing of each refrigeration fin 13, good contact between the refrigeration fin 13 and the heat dissipation device can be ensured, reducing thermal resistance and improving heat transfer efficiency. This helps to achieve a more uniform heat dissipation effect, thereby improving the refrigeration efficiency of the entire refrigeration system.

[0057] Everything in the above example works like this:

[0058] In the initial state: the groove of the refrigeration plate 13 is not in contact with the extrusion plate 37, and the compression spring 302 is not compressed.

[0059] The following is the working process of the clamping and regulating mechanism 2 for opening, closing and fixing the n-shaped slide plate 12:

[0060] When in use, the operator first inserts a single refrigeration plate 13 along the groove in the middle of the refrigeration plate into the threaded transmission rod 34 on the n-shaped slide plate 12. When the operator inserts multiple refrigeration plates 13 into the extrusion plate 37, the operator first manually rotates the first adjustment handle 21, such as Figure 2 As shown, because the first adjusting handle 21 is fixedly connected with a threaded shaft 22, the outer surface of the threaded shaft 22 is threadedly connected with an n-shaped fixing plate 23, both ends of the n-shaped fixing plate 23 are fixedly connected to the support plate 11, and the end of the threaded shaft 22 away from the first adjusting handle 21 is fixedly connected with a turntable 24, so the turntable 24 will start to rotate synchronously when the first adjusting handle 21 is rotated. At this time, because the swing arm 25 rotates symmetrically on the turntable 24, the rotation of the turntable 24 will drive the swing arm 25 to drive the connecting plate 26 to slide on the support plate 11. At this time, because the swing arm 25 A connecting plate 26 is rotatably connected to one end away from the turntable 24, and the outer surfaces of both ends of the connecting plate 26 penetrate the support plate 11. Both ends of the connecting plate 26 are fixedly connected to the n-shaped slide plate 12, so the rotation of the turntable 24 will drive the connecting plate 26 to drive the n-shaped slide plate 12 to clamp the refrigeration plate 13. Since both ends of the extrusion plate 37 are slidably connected to the guide rod 38, and both ends of the guide rod 38 are fixedly connected to the n-shaped slide plate 12, when the first adjustment handle 21 is rotated to make the refrigeration plate 13 initially stable in the extrusion plate 37, the first adjustment handle 21 can be stopped from rotating.

[0061] The clamping and regulating mechanism 2 can be set to adjust the opening and closing of the n-shaped slide plate 12, so that the middle groove of the refrigeration plate 13 can be connected to the extrusion plate 37. By adjusting the lateral extrusion of the refrigeration plate 13, not only can the refrigeration plate 13 always be kept in the center position, but also each refrigeration plate 13 can be firmly clamped in a fixed position, reducing the risk of loosening or displacement caused by vibration or external force.

[0062] The present invention proposes an innovative method for clamping and fixing a refrigeration fin 13. The method retains the traditional clamping method and, by introducing a clamping mechanism that is adjusted jointly by the first adjusting handle 21 and the second adjusting handle 31, achieves accurate clamping and uniform pressure on each refrigeration fin 13. By rotating the first adjusting handle 21 and the second adjusting handle 31, the present invention can ensure that each refrigeration fin 13 is subjected to balanced pressure during the welding process, thereby effectively avoiding the problem of reduced internal quality of the refrigeration fin 13 caused by uneven force at both ends and the middle in the traditional clamping method.

[0063] This design improvement not only reduces the potential damage to the refrigeration fins 13 caused by differences in extrusion stress, but also significantly improves the welding quality of the entire refrigeration fins 13. Traditional clamping methods often cause the refrigeration fins 13 at both ends to be damaged due to excessive force, or the middle refrigeration fins 13 to be loosely welded due to insufficient force. The present invention perfectly solves these problems through precise adjustment and uniform pressure, thereby reducing the reduction in the internal quality of the refrigeration fins 13 caused by different extrusion forces, and further improving the overall welding quality of the refrigeration fins 13.

[0064] Please refer to the above working process Figures 1 to 7 .

[0065] The following is the working process of the uniform extrusion mechanism 3 for uniformly clamping the refrigeration sheet 13:

[0066] As described above, when the refrigeration plate 13 is initially fixed in the extrusion plate 37, the operator rotates the second adjusting handle 31 at this time. Since the transmission wheels 32 are evenly arranged on the multi-functional baffle 35, and one of the transmission wheels 32 is fixedly connected to the second adjusting handle 31, and since the transmission belt 33 is transmission-connected to the transmission wheel 32, the operator rotates the second adjusting handle 31 to drive the transmission wheel 32 to start transmission. Since the transmission wheels 32 on both sides of the multi-functional baffle 35 are fixed to the middle part of the threaded transmission rod 34, and since the multi-functional baffle 35 has grooves on both sides, the non-toothed surface of the outer surface of the threaded transmission rod 34 slides in the grooves, when the clamping and regulating mechanism 2 applies pressure to the refrigeration plate 13 on both sides, since the clamping and regulating mechanism 2 and the uniform extrusion mechanism 3 are linked to each other, When the n-shaped slide plate 12 is adjusted to clamp the refrigeration plate 13, the n-shaped slide plate 12 will be driven to clamp the refrigeration plate 13 groove through the connecting plate 26. At the same time, because the threaded transmission rod 34 is slidably connected in the slide groove provided in the n-shaped slide plate 12, the threaded transmission rod 34 is driven to slide in the slide groove by the rotation of the first adjusting handle 21. At this time, the threaded transmission rod 34 is driven to start rotating through the transmission wheel 32. Since the arc groove 36 is provided on the threaded transmission rod 34, and the extrusion column slidably connected in the arc groove 36 is fixedly connected to the extrusion plate 37, and the two ends of the extrusion plate 37 are slidably connected to the outer surface of the guide rod 38, and the guide rod 38 is fixedly connected to the n-shaped slide plate 12, the rotation of the arc groove 36 will drive the extrusion plate 37 to start sliding on the guide rod 38;

[0067] Since the extrusion plate 37 is engaged with the groove in the middle of the refrigeration plate 13, and the threaded transmission rod 34 to the guide rod 38 are symmetrically arranged on both sides of the refrigeration plate 13, the distance between the refrigeration plates 13 can be adjusted by the extrusion plate 37 engaging and squeezing the groove of the refrigeration plate 13 and then rotating the threaded transmission rod 34 to drive the extrusion plate 37 to slide on the guide rod 38. Different numbers of refrigeration plates 13 can be clamped and fixed respectively by the uniform extrusion mechanism 3. When the refrigeration demand changes, there is no need to replace the entire clamping device, and it can be achieved by simple adjustment. The clamping and fixing of a new number of refrigeration fins 13 improves the flexibility and response speed of the system, and by precisely controlling the clamping spacing of each refrigeration fin 13, it can ensure that each refrigeration fin 13 can achieve standardized welding, so that each refrigeration fin 13 can be welded with standardized spacing, which can not only ensure good contact between the refrigeration fin 13 and the heat dissipation device, improve the overall welding quality, and reduce thermal resistance, but also improve the heat transfer efficiency through high-precision welding quality, which is conducive to achieving a more uniform heat dissipation effect for the refrigeration fins 13 after welding.

[0068] The present invention can not only achieve good heat conduction between the refrigeration plates 13 by setting a uniform welding spacing. In the refrigeration system, the heat conduction efficiency between the refrigeration plates 13 directly affects the performance of the entire system. By optimizing the welding spacing, the present invention can reduce the thermal resistance caused by uneven spacing, improve the heat conduction efficiency, and thus improve the overall performance of the refrigeration system. In the traditional welding method, it may be necessary to adjust the spacing between the refrigeration plates 13 one by one, which is not only time-consuming and labor-intensive, but also prone to errors. The present invention achieves synchronous optimization of the spacing of all refrigeration plates 13 through a one-time adjustment, thereby greatly improving production efficiency.

[0069] In the traditional welding method, due to the inaccurate spacing control, part of the refrigeration plate 13 may be damaged due to uneven heating, or fail due to loose welding. The present invention reduces this risk by improving the welding accuracy and consistency, thereby saving costs.
