Description

Technical Field

[0001] This invention relates to an improvement in heat dissipation technology for weft insertion mechanisms, belonging to the textile field, and particularly to a heat dissipation mechanism with shovel teeth for electromagnetic emission coils. Background Technology

[0002] The ultra-wide width electromagnetic weft insertion mechanism is a weft insertion mechanism designed based on the principle of electromagnetic emission. It uses electromagnetic force to drive components such as the weft clamp or weft insertion shuttle to quickly and accurately introduce the weft yarn into the shed of the loom, thereby achieving efficient weaving of ultra-wide width fabrics. However, during the acceleration process of the electromagnetic weft insertion mechanism, heat accumulates in the electromagnetic coil under long-term working conditions, causing the mechanism to overheat and affecting the service life of the equipment. Existing liquid cooling methods mainly dissipate heat through thermal convection, with cooling water flowing from one end of the liquid cooling plate to the other. In this process, the temperature of the water flowing through the radiator rises. When a single coil is dissipating heat, the temperature of the water flowing through the latter half of the coil is significantly higher than that of the first half, resulting in uneven heat dissipation and thus poor heat dissipation effect.

[0003] Chinese patent application CN 202211687094.5, filed on December 27, 2022, discloses a heat dissipation device for electromagnetic weft insertion. The device includes multiple liquid cooling components and cooling pipes. Adjacent liquid cooling components are connected sequentially, and the cooling pipes are disposed throughout all the liquid cooling components. Each liquid cooling component includes a first liquid cooling plate and a second liquid cooling plate. The back of the first liquid cooling plate is connected to the front of the second liquid cooling plate, and the cooling pipes are disposed throughout the first and second liquid cooling plates. The left side of the first liquid cooling plate is connected to two left-side cooling pipes, and the right side of the first liquid cooling plate is connected to two right-side cooling pipes. An upper liquid flow channel is provided at the upper end of the front side of the first liquid cooling plate. A liquid cooling plate has a lower liquid flow channel at the bottom front. The upper liquid flow channel is connected to a left and a right cooling pipe above, and the lower liquid flow channel is connected to a left and a right cooling pipe below. This design dissipates heat from the coil by water cooling. The water flows in series through all the heat sinks in the upper part and then flows back from the end to the heat sinks in the lower part. However, this design does not solve the problem of uneven heat dissipation.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this patent application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to overcome the problem of uneven heat dissipation in the prior art and to provide a toothed heat dissipation mechanism for electromagnetic emission coils that provides uniform heat dissipation.

[0006] To achieve the above objectives, the technical solution of the present invention is: a heat dissipation mechanism with shovel teeth for an electromagnetic transmitting coil, wherein the heat dissipation mechanism with shovel teeth for an electromagnetic transmitting coil includes multiple heat dissipation mechanisms and heat dissipation pipes, the multiple heat dissipation mechanisms are connected in sequence, and the cooling pipes are disposed through all the heat dissipation mechanisms;

[0007] The heat dissipation mechanism includes symmetrically arranged side liquid cooling plates and main liquid cooling plates, with the front of the side liquid cooling plates and the back of the main liquid cooling plates being attached to each other.

[0008] The side liquid cooling plate includes a first upper heat dissipation plate and a first lower heat dissipation plate. The first upper heat dissipation plate and the first lower heat dissipation plate have the same structure and are symmetrically arranged. A coil is arranged between the first upper heat dissipation plate and the first lower heat dissipation plate, and a magnetic yoke is arranged on the outside of the coil.

[0009] The left side of the inner cavity of the side liquid cooling plate is connected to one end of the first heat dissipation pipe, and the right side of the inner cavity of the side liquid cooling plate is connected to one end of the second heat dissipation pipe. The two second heat dissipation pipes are connected by a first connecting hose.

[0010] The left side of the main liquid cooling plate is connected to one end of two third heat dissipation pipes, and the right side of the main liquid cooling plate is connected to one end of two fourth heat dissipation pipes. The two fourth heat dissipation pipes are connected to each other through a second connecting hose. The adjacent third heat dissipation pipes are connected to the first heat dissipation pipes on the first upper heat dissipation plate through a third connecting hose.

[0012] The third heat dissipation pipe at the bottom front is the water inlet pipe, and the third heat dissipation pipe at the top rear is the water outlet pipe.

[0013] The inner cavities of the first upper heat sink and the first lower heat sink are provided with first shovel teeth, and the inner cavity of the main liquid cooling plate is provided with second shovel teeth.

[0014] The main liquid cooling plate includes a silicone grease overflow baffle, a first leg, and a plate body;

[0015] The plate has four first legs around its sides, each with a connection port. The front and back of the outer side of the plate are equipped with silicone grease overflow baffles. The left side of the inner cavity of the plate is connected to one end of the third heat dissipation pipe, and the right side of the inner cavity of the plate is connected to one end of the fourth heat dissipation pipe.

[0016] The silicone grease overflow baffle has a connector at the center of both the top and bottom, and the bottom of the connector is flush with the outer ring of the plate.

[0017] The outer diameter of the grease overflow baffle is larger than the outer diameter of the plate body.

[0018] The inner cavity of the plate is equipped with a second shovel tooth, the thickness of which ranges from 0.15mm to 1mm.

[0019] The plate is a ring-shaped plate, with four first legs evenly distributed on the side walls of the plate.

[0020] The thickness of the coil and the yoke is adapted to the inner diameter of the plate, and the inner diameter of the coil is the same as the inner diameter of the heat sink.

[0022] The plate has mounting ports on both the left and right sides, and each mounting port contains a sensor.

[0023] Two second legs are installed on the top two sides of the side liquid cooling plate and the bottom two sides of the first lower heat dissipation plate, respectively, and each second leg has a connection port on its front.

[0024] The four second legs correspond one-to-one with the four first legs and are connected by bolts through the connection ports.

[0025] Both the first upper heat sink and the first lower heat sink are semi-annular plates, and the first upper heat sink and the first lower heat sink are connected to each other.

[0026] The first heat pipe, the second heat pipe, and the third heat pipe have the same diameter.

[0027] The first connecting hose, the second connecting hose, the third connecting hose, and the fourth connecting hose have the same structure.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0029] 1. In a toothed heat dissipation mechanism for an electromagnetic transmitting coil, the left side of the inner cavity of the side liquid cooling plate is connected to one end of a first heat dissipation pipe, and the right side of the inner cavity of the side liquid cooling plate is connected to one end of a second heat dissipation pipe. The two second heat dissipation pipes are connected by a first connecting hose. The left side of the main liquid cooling plate is connected to one end of two third heat dissipation pipes, and the right side of the main liquid cooling plate is connected to one end of two fourth heat dissipation pipes. The two fourth heat dissipation pipes are connected by a second connecting hose. Adjacent third heat dissipation pipes are connected to the first heat dissipation pipes on the first upper heat dissipation plate by a third connecting hose. In application, cooling water enters the third heat dissipation pipe at the bottom front from the inlet pipe, flows into the first heat dissipation pipe in the first upper heat dissipation plate through the third connecting hose, flows into the second heat dissipation pipe through the first connecting hose, flows into the first heat dissipation pipe in the first lower heat dissipation plate through the fourth connecting hose, and then flows into the first heat dissipation pipe in the first lower heat dissipation plate through the third connecting hose. The water flows into the adjacent third heat dissipation pipe via a flexible hose, then through the third and fourth heat dissipation pipes within the main liquid cooling plate, and finally exits through the outlet pipe. Cooling is achieved through the circulation of cooling water on the coil surface. As the cooling water flows through the first upper and lower heat dissipation plates, it is forced to change direction by passing the first and second shovel teeth, transforming from a relatively straight flow into a tortuous flow that bypasses the teeth, thus creating turbulence. In turbulent flow, the fluid mixes more thoroughly, resulting in a more uniform temperature distribution within the fluid. This helps maintain uniform heat dissipation and avoids localized overheating or undercooling. Simultaneously, as the cooling water flows through the first and second shovel teeth, more vortices and disturbances are generated, leading to more frequent and closer contact between the cooling water and the radiator surface. This increases the effective heat exchange area between the cooling water and the radiator per unit volume, thereby improving heat dissipation efficiency. Therefore, this invention provides uniform heat dissipation and faster liquid flow.

[0030] 2. In the toothed heat dissipation mechanism for an electromagnetic transmitting coil of the present invention, a uniform slurry-like thermally conductive silicone grease is applied between the coil and the yoke, between the yoke and the first upper heat dissipation plate and the first lower heat dissipation plate, between the first upper heat dissipation plate and the first lower heat dissipation plate, and between the coil. In application, both the first upper and first lower heat dissipation plates are semi-annular plates, and the main liquid cooling plate adopts an upper and lower structure, which is easy to install and can better adapt to the shape of the coil, ensuring uniform distribution of coolant within the heat dissipation plate and improving heat dissipation efficiency. The uniform application of the slurry-like thermally conductive silicone grease ensures good thermal contact between various components, improving the overall reliability of the system. Therefore, the present invention has high heat dissipation efficiency and stable connection.

[0031] 3. In the toothed heat dissipation mechanism for an electromagnetic transmitting coil of the present invention, the first, second, and third heat dissipation pipes have the same diameter. This design ensures that the flow velocity and flow rate of the coolant are consistent in each heat dissipation pipe, improving the uniformity of heat dissipation. The first, second, third, and fourth connecting hoses have identical structures. This design ensures that the flow resistance of the coolant is consistent in each connecting hose, further improving the uniformity of heat dissipation and adapting to the heat dissipation requirements under different operating conditions. Therefore, the present invention is applicable to various operating conditions and provides more uniform heat dissipation. Attached Figure Description

[0060] The silicone grease overflow baffle 21 has a connector 23 at the top and bottom center, and the bottom of the connector 23 is flush with the outer ring of the plate body 24.

[0061] The outer diameter of the grease overflow baffle 21 is larger than the outer diameter of the plate body 24.

[0062] The inner cavity of the plate 24 is equipped with a second shovel tooth 26, the thickness of which ranges from 0.15mm to 1mm.

[0063] The plate 24 is an annular plate, and the four first legs 22 are evenly distributed on the side of the plate 24.

[0072] The following are supplementary descriptions of the present invention:

[0073] In a straight-flow channel, the fluid typically flows in a laminar manner, with high velocity in the middle and low velocity at the boundaries. The interface between the fluid and the channel wall is basically in an undisturbed equilibrium state. Increasing the velocity gradient and shear stress can break this equilibrium, causing more interaction and mixing between the fluid layers and forming vortices. These vortices will bring the coolant from the center of the channel to the vicinity of the wall, increasing the contact area between the fluid and the wall, thereby improving heat dissipation efficiency.

[0074] Example 1:

[0075] A toothed heat dissipation mechanism for an electromagnetic emission coil includes multiple heat dissipation mechanisms and heat dissipation pipes 3. The heat dissipation mechanisms are sequentially connected, and the heat dissipation pipes 3 are disposed throughout all the heat dissipation mechanisms. Each heat dissipation mechanism includes symmetrically arranged side liquid cooling plates 1 and main liquid cooling plates 2, with the front of the side liquid cooling plates 1 and the back of the main liquid cooling plates 2 in contact. Each side liquid cooling plate 1 includes a first upper heat dissipation plate 11 and a first lower heat dissipation plate 10, which are symmetrically arranged with identical structures. A coil 9 is disposed between the first upper heat dissipation plate 11 and the first lower heat dissipation plate 10, and a magnetic yoke 91 is disposed on the outside of the coil 9. The left side of the inner cavity of the side liquid cooling plate 1 is connected to one end of a first heat dissipation pipe 12, and the right side of the inner cavity of the side liquid cooling plate 1 is connected to one end of a second heat dissipation pipe 13. The two second heat dissipation pipes 13 are connected by a first connecting hose 15; the left side of the main liquid cooling plate 2 is connected to one end of the two third heat dissipation pipes 6, and the right side of the main liquid cooling plate 2 is connected to one end of the two fourth heat dissipation pipes 5. The two fourth heat dissipation pipes 5 are connected by a second connecting hose 4. The adjacent third heat dissipation pipes 6 are connected to the first heat dissipation pipes 12 on the first upper heat dissipation plate 11 by a third connecting hose 7. The first heat dissipation pipes 12 on the first lower heat dissipation plate 10 are connected to the adjacent lower third heat dissipation pipes 6 by a fourth connecting hose 8. The third heat dissipation pipe 6 at the frontmost lower side is the water inlet pipe, and the third heat dissipation pipe 6 at the rearmost upper side is the water outlet pipe. The inner cavities of the first upper heat dissipation plate 11 and the first lower heat dissipation plate 10 are provided with first shovel teeth 14, and the inner cavity of the main liquid cooling plate 2 is provided with second shovel teeth 26.

[0076] In application: Turn on the cooling water pump to allow cooling water to enter the heat dissipation mechanism through the inlet pipe. The cooling water enters the third heat dissipation pipe 6 at the bottom front of the inlet pipe, flows into the first heat dissipation pipe 12 inside the first upper heat dissipation plate 11 through the third connecting hose 7, flows into the second heat dissipation pipe 13 through the first connecting hose 15, flows into the first heat dissipation pipe 12 inside the first lower heat dissipation plate 10 through the fourth connecting hose 8, flows into the adjacent third heat dissipation pipe 6 through the third connecting hose 7, flows through the third heat dissipation pipe 6 and the fourth heat dissipation pipe 5 inside the main liquid cooling plate 2, and finally flows out from the outlet pipe. When the cooling water flows through the first upper heat dissipation plate 11 and the first lower heat dissipation plate 10, the first shovel teeth 14 increase turbulence and improve the heat dissipation efficiency. When the cooling water flows through the main liquid cooling plate 2, the second shovel teeth 26 increase turbulence and further improve the heat dissipation efficiency.

[0077] Example 2:

[0078] Example 2 is basically the same as Example 1, except that:

[0079] The main liquid cooling plate 2 includes a grease overflow baffle 21, first legs 22, and a plate body 24. Four first legs 22 are arranged around the sides of the plate body 24, each with a connection port. Grease overflow baffles 21 are arranged on both the front and back of the outer perimeter of the plate body 24. The left side of the inner cavity of the plate body 24 is connected to one end of the third heat dissipation pipe 6, and the right side is connected to one end of the fourth heat dissipation pipe 5. Connector ports 23 are provided at the top and bottom center of the grease overflow baffle 21, with the bottom of the connector ports 23 flush with the outer ring of the plate body 24. The outer diameter of the grease overflow baffle 21 is larger than the outer diameter of the plate body 24. The inner cavity of the plate body 24 is fitted with... The plate 24 is equipped with a second shovel tooth 26, the thickness of which ranges from 0.15mm to 1mm. The plate 24 is an annular plate, with four first legs 22 evenly distributed on the side of the plate 24. The thickness of the coil 9 and the magnetic yoke 91 is adapted to the inner diameter of the plate 24, and the inner diameter of the coil 9 is the same as the inner diameter of the heat sink 3. A uniform layer of mud-like thermal conductive silicone grease is applied between the coil 9 and the magnetic yoke 91, between the magnetic yoke 91 and the first upper heat sink 11 and the first lower heat sink 10, between the first upper heat sink 11 and the first lower heat sink 10, and between the coil 9. Mounting ports 25 are provided on both the left and right sides of the plate 24, and a sensor is installed in each mounting port 25.

[0080] In application: The second spade 26 installed in the inner cavity of the plate 24 has a thickness ranging from 0.15mm to 1mm, which can effectively increase the turbulence of the coolant and improve the heat dissipation efficiency. This allows the coolant to make more full contact with the heat dissipation plate when flowing through it, thereby more effectively removing heat. The thermal grease overflow baffle 21 can prevent the thermal grease from overflowing, ensuring that the thermal grease is evenly distributed on each contact surface and improving the heat conduction efficiency. The outer diameter of the thermal grease overflow baffle 21 is larger than the outer diameter of the plate 24, further ensuring that the thermal grease will not overflow to the outside, keeping the heat dissipation system clean and efficient. Four first legs 22 are provided around the sides of the plate 24, and each first leg 22 has a connection port. This design can ensure the stable connection of the heat dissipation mechanism and improve the stability of the overall structure.

[0081] Example 3:

[0082] Example 3 is basically the same as Example 1, except that:

[0083] Two second legs 16 are installed on the top two sides of the side liquid cooling plate 1 and the bottom two sides of the first lower heat sink 10, respectively. Each second leg 16 has a connection port on its front. The four second legs 16 correspond one-to-one with the four first legs 22 and are connected by bolts through the connection ports. The first upper heat sink 11 and the first lower heat sink 10 are both semi-annular plates and are connected to each other. The first heat sink 12, the second heat sink 13 and the third heat sink 6 have the same diameter. The first connecting hose 15, the second connecting hose 4, the third connecting hose 7 and the fourth connecting hose 8 have the same structure.

[0084] In application: Two second legs 16 are installed on the top two sides of the side liquid cooling plate 1 and the bottom two sides of the first lower heat sink 10, respectively, with a connection port on the front of each second leg 16. This design provides additional support points through the legs, enhancing the structural stability of the heat sink. Both the first upper heat sink 11 and the first lower heat sink 10 are semi-annular plates. This design not only improves heat dissipation efficiency but also facilitates installation and maintenance. The semi-annular plates can better adapt to the shape of the coil 9, ensuring uniform distribution of coolant within the heat sink.

[0085] Example 4:

[0086] Example 4 is basically the same as Example 1, except that:

[0087] See Figures 12 to 16The simulation included an inlet and outlet for a liquid, with water as the liquid material and copper as the liquid cooling plate material. The initial liquid temperature was 20°C, the inlet velocity was 0.8 m / s, and the outlet pressure was the same as atmospheric pressure. The heat source power was 500 W. The simulation results showed that the liquid cooling plate with serrated teeth had a significantly better heat dissipation effect than the one without. Adding serrations can improve the heat dissipation effect by increasing the heat dissipation area. Since a simplified electromagnetic coil heat source model was used in this simulation, the simulation results were significantly different. The liquid cooling plate with serrated teeth was 40°C cooler than the one without. In reality, there are many poor heat conductors inside and on the surface of the coil. The liquid cooling plate with serrated teeth can improve the heat dissipation effect, but it will be lower than the effect in the simulation.
