Description

Technical Field

[0001] This utility model relates to the field of magnetic core coil clamping technology, specifically to a heat dissipation clamp for amorphous magnetic core coils. Background Technology

[0002] Amorphous magnetic core coils are core electromagnetic components made of amorphous magnetic materials. Due to their excellent permeability and low iron loss, they are widely used in power electronics, communications, and new energy fields. Their performance stability is closely related to processing precision. During the production and processing of amorphous magnetic core coils, whether it's winding, impregnation and curing, or subsequent testing and assembly, specialized fixtures are required for positioning and fixing to ensure the accuracy of processing operations and the integrity of the coil structure. Existing amorphous magnetic core coil fixtures typically use a rigid base for support, with an adjustable clamping mechanism on the base. This mechanism usually consists of clamping blocks and drive components, ensuring the amorphous magnetic core coil maintains a stable posture during each processing step, providing a fundamental guarantee for the smooth operation of subsequent production stages.

[0003] During the production of existing amorphous magnetic core coils, factors such as winding friction, impregnation curing reaction, and electromagnetic induction energy conversion cause the amorphous magnetic core coils to heat up. When existing clamps hold the amorphous magnetic core coils, the clamps enclose the amorphous magnetic core coils, making it difficult for the heat to dissipate. This leads to heat accumulation in the amorphous magnetic core coils, which may cause damage to the coil insulation layer and thermal deformation of the product, ultimately affecting the quality and performance of the finished coil. Therefore, a heat dissipation clamp for amorphous magnetic core coils is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a heat dissipation fixture for amorphous magnetic core coils, which solves the problem mentioned in the background art where the existing fixtures have poor heat dissipation when clamping amorphous magnetic core coils, leading to heat accumulation in the amorphous magnetic core coils, which may cause damage to the coil insulation layer and thermal deformation of the product.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A heat dissipation clamp for amorphous magnetic core coils, comprising a base, two clamping blocks mounted on the base, the clamping blocks being hollow, a heat dissipation assembly mounted on the clamping blocks, the heat dissipation assembly including a liquid tank mounted on the base, two telescopic tubes connecting the liquid tank and the clamping blocks, a connecting pipe mounted on the side of the liquid tank near the clamping blocks, a liquid cylinder connected to the connecting pipe, a piston slidably connected to the inner wall of the liquid cylinder, an inner tube slidably connected through the side of the liquid cylinder near the clamping blocks, the piston being connected to the inner tube, which in turn connects the inner tube to the clamping blocks, a connector being connected to the outer wall of the inner tube, a cylinder mounted on the outer wall of the liquid tank, the output end of the cylinder being connected to the connector.

[0006] Preferably, both the connecting pipe and the inner pipe are equipped with a one-way valve. When the piston moves toward the connecting pipe, it can squeeze the coolant in the liquid cylinder into the clamping block through the inner pipe. When the piston moves away from the connecting pipe, it can draw the coolant in the liquid tank into the liquid cylinder through the connecting pipe.

[0007] Preferably, the clamping block is equipped with a plurality of heat sinks, some of which are located inside the clamping block and some of which are located outside the clamping block.

[0008] Preferably, the liquid tank is equipped with a plurality of first baffles and a plurality of pairs of second baffles, the plurality of first baffles and the plurality of pairs of second baffles being staggered, the plurality of first baffles and the plurality of pairs of second baffles working together to deflect the flow and extend the flow path of the coolant in the liquid tank.

[0009] Preferably, both the first baffle and the second baffle are made of materials with high thermal conductivity, and a portion of both the first baffle and the second baffle is located outside the liquid tank.

[0010] Preferably, the clamping block is provided with a flow-dispersing part, which includes a triangular rod. The triangular rod is installed inside the clamping block and is located next to the connection position between the inner tube and the clamping block. Two flow-dispersing plates are hinged to the triangular rod, and the two flow-dispersing plates are arranged in a mirror image.

[0011] Preferably, a water wheel is rotatably mounted at the connection between the inner tube and the clamping block, a rotating shaft is connected to the water wheel, the rotating shaft is rotatably connected to a triangular rod, an elliptical wheel is connected to the end of the rotating shaft away from the water wheel, a leaf spring is connected between the two spoilers, and when the elliptical wheel rotates, it slides in contact with the two spoilers and drives the two spoilers to swing back and forth.

[0012] As can be seen from the above technical solutions, the amorphous magnetic core coil heat dissipation clamp provided in the embodiments of this specification has at least the following beneficial effects: 1. This utility model, through the cooperation of the clamping block and the heat dissipation component, enables the coolant in the clamping block to absorb the heat of the amorphous magnetic core coil it clamps, thereby achieving a better heat dissipation effect. Furthermore, after each clamping operation, the coolant in the clamping block that has absorbed heat can be replaced by a low-temperature coolant, thus ensuring the heat dissipation effect of each clamping operation.

[0013] 2. This utility model, through the setting of the flow-deflecting part, forms a V-shaped flow-guiding structure with the triangular rod and the two flow-deflecting plates, which can evenly guide the coolant entering the clamping block to both sides of the two flow-deflecting plates, so that the coolant flows into each area of ​​the clamping block more evenly, thereby ensuring the replacement effect of the coolant; through the continuous rotation of the elliptical wheel and the cooperation of the leaf spring, the two flow-deflecting plates realize high-frequency reciprocating oscillation, which strongly disturbs the coolant in the clamping block, avoiding the high-temperature coolant near the inner wall of the clamping block from being left behind due to slow flow, thus improving the replacement efficiency of low-temperature coolant and high-temperature coolant.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1

[0018] Please see Figures 1-5As shown, an amorphous magnetic core coil heat dissipation clamp includes a base 1, on which two clamping blocks 2 are mounted. Each clamping block 2 is hollow and has a heat dissipation assembly 3. The heat dissipation assembly 3 includes a liquid tank 33 mounted on the base 1. Two telescopic tubes 32 connect the liquid tank 33 to the clamping blocks 2, and the telescopic tubes 32 are telescopic. A connecting pipe 36 is mounted on the side of the liquid tank 33 closest to the clamping blocks 2, and a liquid cylinder 37 is connected to the connecting pipe 36. A piston 38 is slidably connected to the inner wall of the liquid cylinder 37. An inner tube 39 is slidably connected through the liquid cylinder 37 near the clamping block 2. The piston 38 is connected to the inner tube 39, which in turn connects the inner tube 39 to the clamping block 2. A connector 310 is connected to the outer wall of the inner tube 39. A cylinder 4 is installed on the outer wall of the liquid tank 33. The output end of the cylinder 4 is connected to the connector 310. The two clamping blocks 2 are components that directly contact the amorphous magnetic core coil. Their hollow structure provides space for the storage and flow of coolant. The clamping blocks 2, telescopic... The pipe 32, liquid tank 33, connecting pipe 36, liquid cylinder 37, and inner pipe 39 are all filled with coolant. During clamping, the two cylinders 4 are driven to extend. The two cylinders 4, through the two connecting pieces 310, drive the two inner pipes 39 to move closer together. The two inner pipes 39 drive the two clamping blocks 2 to move closer together, thereby clamping the amorphous magnetic core coil with the two clamping blocks 2. When the clamping blocks 2 clamp and fix the crystalline magnetic core coil, the heat of the crystalline magnetic core coil is transferred to the inner wall of the clamping blocks 2, and the coolant inside the clamping blocks 2 is cooled. The liquid absorbs heat to achieve a heat dissipation effect. When the clamping is released, the two cylinders 4 are driven to contract, and the two clamping blocks 2 move away from each other and reset, thereby releasing the clamping. One-way valves are provided inside the connecting pipe 36 and the inner pipe 39. When the piston 38 moves towards the connecting pipe 36, it can squeeze the coolant in the liquid cylinder 37 into the clamping block 2 through the inner pipe 39. When the piston 38 moves away from the connecting pipe 36, it can draw the coolant in the liquid tank 33 into the liquid cylinder 37 through the connecting pipe 36.Taking one of the clamping blocks 2 as an example, when the clamping is released, the cylinder 4 drives the inner tube 39 and piston 38 to move closer to the connecting tube 36 via the connecting piece 310. This compresses the internal space of the liquid cylinder 37, increasing the pressure. At this time, the one-way valve in the inner tube 39 opens under pressure, while the one-way valve in the connecting tube 36 closes. The coolant in the liquid cylinder 37 is smoothly squeezed into the inner tube 39 and then flows into the clamping block 2. The original coolant in the clamping block 2 is squeezed into the liquid tank 33 through the two telescopic tubes 32. When clamping, the piston 38 and inner tube 39 move away from the connecting tube 36. As the piston moves in the direction of rotation, the internal space of the liquid cylinder 37 expands, creating a negative pressure. Under this negative pressure, the one-way valve in the connecting pipe 36 opens, while the one-way valve in the inner pipe 39 closes. The coolant in the liquid tank 33 is then drawn into the liquid cylinder 37 through the connecting pipe 36, replenishing the coolant in the liquid cylinder 37. Through the reciprocating motion of the piston 38, the coolant continuously circulates between the liquid tank 33, the liquid cylinder 37, the inner pipe 39, the clamping block 2, and the telescopic pipe 32, ensuring that the clamping block 2 always has a constant supply of low-temperature coolant to replace the coolant that has absorbed heat, thus guaranteeing the heat dissipation efficiency of the clamping block 2.

[0019] Furthermore, multiple heat sinks 31 are installed on the clamping block 2. Part of the heat sinks 31 are located inside the clamping block 2, and part of them are located outside the clamping block 2. The heat sinks 31 are made of a material with high thermal conductivity. Part of them extends into the clamping block 2, allowing direct contact with the coolant inside and rapid absorption of the heat stored in the coolant. The other part is exposed outside the clamping block 2, in direct contact with the air, dissipating the absorbed heat to the surrounding environment through heat convection and radiation, thereby improving the heat dissipation effect of the clamping block 2. The liquid tank 33 is equipped with... There are multiple first baffles 34 and multiple pairs of second baffles 35. The multiple first baffles 34 and multiple pairs of second baffles 35 are staggered. The multiple first baffles 34 and multiple pairs of second baffles 35 work together to deflect the flow and extend the flow path of the coolant in the liquid tank 33. The first baffles 34 and the second baffles 35 are both made of high thermal conductivity materials. A portion of each of the first baffles 34 and the second baffles 35 is located outside the liquid tank 33. The first baffles 34 and the second baffles 35 are staggered in the liquid tank 33, forming a tortuous coolant flow channel. When the coolant, having absorbed heat from the clamping block 2, flows back to the liquid tank 33 through the telescopic pipe 32, it does not flow directly and rapidly from the inlet to the outlet of the liquid tank 33. Instead, it flows slowly along a tortuous path under the obstruction and guidance of the staggered first baffle 34 and second baffle 35. This baffle structure significantly extends the residence time and flow path of the coolant within the liquid tank 33, allowing the coolant more time to participate in heat exchange, thereby gradually releasing heat to the outside of the liquid tank 33. When the coolant flows through the path formed by 35, the heat in the coolant is quickly transferred to the first baffle 34 and the second baffle 35. Since part of the baffle is exposed outside the liquid tank 33, the heat absorbed from the coolant is dissipated into the air, further enhancing the cooling effect of the liquid tank 33 on the coolant. This allows the liquid tank 33 to have both storage and heat dissipation functions, and can quickly reduce the temperature of the returning coolant to close to the initial temperature, ensuring that the heat dissipation efficiency of the entire coolant circulation system is always at a high level, providing continuous heat dissipation support for the amorphous magnetic core coil.

[0020] In this embodiment, the cooperation between the clamping block 2 and the heat dissipation component 3 enables the coolant in the clamping block 2 to absorb the heat of the amorphous magnetic core coil it clamps, achieving a better heat dissipation effect. Furthermore, after each clamping operation, the coolant in the clamping block 2 that has absorbed heat can be replaced by a low-temperature coolant, thereby ensuring the heat dissipation effect of each clamping operation.

[0021] Example 2 Please see Figure 3 , Figure 5 , Figure 6As shown, a flow-dispersing part 5 is provided inside the clamping block 2. The flow-dispersing part 5 includes a triangular rod 53, which is installed inside the clamping block 2. The triangular rod 53 is located next to the connection position between the inner tube 39 and the clamping block 2. Two flow-dispersing plates 54 are hinged on the triangular rod 53, and the two flow-dispersing plates 54 are arranged in a mirror image. The triangular rod 53 is located in the inlet area where the coolant enters the clamping block 2. The triangular rod 53 and the two flow-dispersing plates 54 form a V-shaped flow-guiding structure, which can evenly guide the coolant entering the clamping block 2 to both sides of the two flow-dispersing plates 54, so that the coolant flows into each area of ​​the clamping block 2 more evenly, thereby ensuring the replacement effect of the coolant.

[0022] A water wheel 51 is rotatably mounted at the connection between the inner tube 39 and the clamping block 2. A rotating shaft 52 is connected to the water wheel 51, and the rotating shaft 52 is rotatably connected to a triangular rod 53. An elliptical wheel 55 is connected to the end of the rotating shaft 52 away from the water wheel 51. A leaf spring 56 is connected between the two baffles 54. When the elliptical wheel 55 rotates, it slides into contact with the two baffles 54 and drives the two baffles 54 to swing back and forth. When coolant flows from the inner tube 39 into the clamping block 2, the water flow impacts the blades of the water wheel 51, driving the water wheel 51 to rotate. When the water wheel 51 rotates, it drives the elliptical wheel 55 to rotate synchronously through the rotating shaft 52. During the rotation, the elliptical wheel 55 periodically squeezes the two baffles. The inner side of 54 forces the spoiler 54 to swing outward, while the leaf spring 56 connecting the two spoilers 54 has an elastic reset function. When the major axis of the elliptical wheel 55 rotates away from the spoiler 54, the elastic force of the leaf spring 56 will pull the spoiler 54 to reset inward. Through the continuous rotation of the elliptical wheel 55 and the cooperation of the leaf spring 56, the two spoilers 54 realize high-frequency reciprocating swing, which strongly disturbs the coolant in the clamping block 2, avoids the high temperature coolant near the inner wall of the clamping block 2 from being left behind due to slow flow, improves the replacement efficiency of low temperature coolant and high temperature coolant, and also promotes the contact between the coolant and the heat sink 31, further improving the heat dissipation effect.

[0023] In this embodiment, the deflector 5 forms a V-shaped flow guide structure with the triangular rod 53 and the two deflector plates 54, which can evenly guide the coolant entering the clamping block 2 to both sides of the two deflector plates 54, so that the coolant flows into each area of ​​the clamping block 2 more evenly, thereby ensuring the replacement effect of the coolant. Through the continuous rotation of the elliptical wheel 55 and the cooperation of the leaf spring 56, the two deflector plates 54 realize high-frequency reciprocating oscillation, which strongly disturbs the coolant in the clamping block 2, avoids the high-temperature coolant near the inner wall of the clamping block 2 from being left behind due to slow flow, and improves the replacement efficiency of low-temperature coolant and high-temperature coolant.

[0024] In the use of this amorphous magnetic core coil heat dissipation clamp, during clamping operations, two cylinders 4 are driven to extend, thereby driving two clamping blocks 2 to move closer together through two inner tubes 39, clamping the amorphous magnetic core coil. At this time, the heat generated by the coil is transferred to the inner wall of the clamping blocks 2, and the pre-stored coolant in the clamping blocks 2 directly absorbs the heat, achieving heat dissipation. At the same time, multiple heat dissipation fins 31 of the clamping blocks 2 further absorb the heat from the coolant and dissipate it into the air through the external part, enhancing the heat dissipation effect. When the clamping is released, the two clamping blocks 2 move away from each other, and the piston 38 moves towards the connecting pipe 36. The low-temperature coolant in the liquid cylinder 37 is squeezed into the clamping blocks 2, while the coolant that has absorbed heat in the clamping blocks 2 is discharged through the telescopic tube 3. 2. When the coolant flows back to the liquid tank 33 and is clamped again, the piston 38 moves away from the connecting pipe 36, creating a negative pressure in the liquid cylinder 37. The low-temperature coolant in the liquid tank 33 is drawn into the liquid cylinder 37 to replenish it. Through the reciprocating motion of the piston 38, the coolant continuously circulates between the liquid tank 33, the liquid cylinder 37, the inner pipe 39, the clamping block 2, and the telescopic pipe 32, ensuring that there is always low-temperature coolant in the clamping block 2 to replace the coolant after heat absorption. The coolant flowing back to the liquid tank 33 is efficiently cooled by the baffles. The first baffle 34 and the second baffle 35, which are staggered in the liquid tank 33, are both made of high thermal conductivity materials and are partially exposed, forming a tortuous channel, extending the flow path and residence time of the coolant. The baffles then dissipate the absorbed heat through the external part, quickly reducing the temperature of the coolant.

[0025] When the coolant flows into the clamping block 2, it impacts the water wheel 51. The water wheel 51 drives the elliptical wheel 55 to rotate through the rotating shaft 52. The elliptical wheel 55 periodically squeezes the two mirrored baffles 54. With the elastic reset of the leaf spring 56, the baffles 54 oscillate at high frequency. On the one hand, the V-shaped structure formed by the triangular rod 53 and the baffles 54 guides the coolant evenly to each area of ​​the clamping block 2. On the other hand, the oscillating baffles 54 disturb the coolant, avoiding high-temperature coolant residue, improving the coolant replacement efficiency and the heat exchange effect of the heat sink 31, and ultimately providing stable and efficient heat dissipation support for the amorphous magnetic core coil.

Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model. The patent protection scope of the present utility model should be defined by the claims.
