Description

Technical Field

[0001] This utility model relates to the technical field of silicone calendering equipment, specifically to a thermally conductive silicone calendering heat dissipation structure. Background Technology

[0002] Thermally conductive silicone is a silicon-based material with high thermal conductivity, widely used in electronic devices and industrial applications requiring efficient heat dissipation. It primarily improves heat dissipation efficiency by filling the gaps between electronic components and heat sinks, increasing the contact area, and reducing thermal resistance. Thermally conductive silicone also possesses excellent thermal conductivity, electrical insulation, flexibility, and weather resistance, making it an ideal material for thermal management of electronic devices.

[0003] The production of thermally conductive silicone requires the use of a calender for calendering. A calender consists of two or more rollers arranged in a certain pattern. Traditional calenders often lack internal cooling structures, causing the surface temperature of the calender rollers to remain at a high level for extended periods during operation, which can damage the material. In such cases, the machine needs to be stopped for cooling. However, traditional shutdown cooling is mostly natural cooling, which reduces the heat dissipation efficiency of the rollers during actual processing, thereby reducing the overall production speed of thermally conductive silicone and making it impractical. Therefore, this utility model proposes a thermally conductive silicone calendering heat dissipation structure. Utility Model Content

[0004] The purpose of this invention is to provide a thermally conductive silicone rolled heat dissipation structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a thermally conductive silicone calendering heat dissipation structure, including a lower base, a primary frame fixedly installed on one side of the upper surface of the lower base, and a secondary frame fixedly installed on the other side of the upper surface of the lower base. Two calendering rollers are rotatably installed between the primary and secondary frames via bearings. Each of the two calendering rollers has an inner cavity, and a water-cooling pipe is installed inside the inner cavity. The water-cooling pipe adopts a spiral structure design and spirally wraps around the inner cavity. Upper columns are fixedly installed on the upper surfaces of both the primary and secondary frames. An upper top plate is fixedly installed between the two upper columns. Several cooling fans are fixedly installed on the upper surface of the upper top plate by bolts, and the cooling fans are linearly distributed at equal intervals.

[0006] Preferably, one end of the water-cooling pipe is connected to a water inlet connector, and the other end of the water-cooling pipe is connected to a water outlet connector.

[0007] Preferably, the water inlet connector and the water outlet connector are fixedly installed on the outer walls of both sides of the calender roll by screws.

[0008] Preferably, a roller shaft is fixedly installed on the outer wall of the center position on both sides of the two calendering rollers, and a gear is fixedly installed on one side of the roller shaft.

[0009] Preferably, the gears between the two calendering rolls are connected by a belt drive.

[0010] Preferably, the number of cooling fans is not less than three.

[0011] Preferably, the water-cooling pipe has at least six turns, and the water-cooling pipe is a copper pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention utilizes water-cooling pipes to provide internal water-cooling heat exchange and cooling for the calender rolls, resulting in superior water-cooling performance. It allows for rapid water-cooling of the calender rolls when they overheat, increasing the cooling rate. Compared to traditional natural cooling, this invention's pipe-type water-cooling effectively improves the overall cooling speed of the roll body, enhancing performance and reducing machine downtime. This increases the overall production efficiency and speed of the calender, making it more practical. Furthermore, the spiral-shaped water-cooling pipes effectively increase the contact area with the roll body, further improving the water-cooling heat exchange effect and overall performance.

[0014] Furthermore, the cooling fan can provide air cooling to the outside of the calendering rolls, effectively helping to lower the external temperature of the rolls through physical airflow. This also reduces the rate of temperature rise of the rolls, providing a certain degree of air cooling effect and good practicality. It allows both rolls to be cooled during calendering operations, improving the overall performance. When used in conjunction with water cooling pipes, the thermally conductive silicone calendering structure of this invention provides dual cooling effects, including internal water cooling and external air cooling, effectively improving the heat dissipation performance of the rolls, accelerating cooling efficiency, and resulting in better performance.

[0024] Please see Figure 1-5 The present invention provides an embodiment of a thermally conductive silicone calendering heat dissipation structure, comprising a lower base 1, a primary frame 2 fixedly installed on one side of the upper surface of the lower base 1, and a secondary frame 3 fixedly installed on the other side of the upper surface of the lower base 1. Two calendering rollers 4 are rotatably installed between the primary frame 2 and the secondary frame 3 via bearings. The two calendering rollers 4 ensure the normal calendering operation of the thermally conductive silicone production and guarantee its normal use effect.

[0025] Please refer to the instruction manual for details. Figures 3-5 As shown, both calendering rolls 4 have an inner cavity 8 inside, and a water cooling pipe 9 is installed inside the inner cavity 8. The water cooling pipe 9 adopts a spiral structure design and is spirally wrapped inside the inner cavity 8. The number of turns of the water cooling pipe 9 is not less than six. The water cooling pipe 9 is made of copper. The use of copper pipe can effectively improve the water cooling effect, has good conductivity, and has low operating cost.

[0026] The water-cooling pipe 9 allows for water-cooled heat exchange and cooling of the interior of the calender roll 4, providing a better water-cooling effect. It can quickly cool the calender roll 4 when it is overheated, increasing the cooling speed. Compared to traditional natural cooling, this invention uses a pipe-type water-cooling system to effectively improve the overall cooling speed of the roll body, thus improving the performance and reducing machine downtime. This increases the overall production efficiency and speed of the calender, making it more practical. Furthermore, the spiral-shaped water-cooling pipe 9 effectively increases the contact area with the roll body, enhancing the water-cooling heat exchange effect and resulting in better performance.

[0027] In order to facilitate heat dissipation treatment of the exterior of the calender roll 4 and ensure that it can also dissipate heat during operation, upper columns 5 are fixedly installed on the upper surfaces of the first-stage frame 2 and the second-stage frame 3. An upper top plate 6 is fixedly installed between the two upper columns 5. Several cooling fans 7 are fixedly installed on the upper surface of the upper top plate 6 by bolts. The cooling fans 7 are linearly distributed at equal intervals, and the number of cooling fans 7 is not less than three.

[0028] This structural design, through the installed cooling fan 7, can provide air cooling treatment to the outside of the calendering roll 4, effectively helping the roll body to cool down physically by blowing air, while reducing the heating rate of the roll body. It has a certain air cooling effect, is highly practical, and allows the two roll bodies to be cooled down during calendering operations, thus improving the performance.

[0029] In this embodiment, in order to facilitate the injection and discharge of coolant into the water-cooling pipe 9 inside the calendering roll 4 and help it to circulate water cooling and heat dissipation, one end of the water-cooling pipe 9 is connected to a water inlet connector 10 and the other end of the water-cooling pipe 9 is connected to a water outlet connector 11.

[0030] The inlet connector 10 and the outlet connector 11 are respectively fixedly installed on the outer walls of the two sides of the calendering roll 4 by screws;

[0031] In practical use, the inlet connector 10 and outlet connector 11 can be connected to the water cooling system through pipes. The water tank of the water cooling system is connected to the inlet of the circulation pump through a pipe, the outlet of the circulation pump is connected to the inlet connector 10 through a pipe, and the outlet connector 11 is connected to the outlet of the water tank through a pipe. This forms a water cooling circulation system for cooling the roller body, ensuring that it can perform normal pipe connection water cooling and heat dissipation when the machine is stopped.

[0032] In this embodiment, in order to ensure the normal use of the calendering roller 4 of this utility model, roller shafts 12 are fixedly installed on the outer walls of the center positions on both sides of the two calendering rollers 4, and a gear 13 is fixedly installed on one side of the roller shaft 12.

[0033] For details, please refer to the appendix of the instruction manual. Figure 1 As shown, the gear 13 between the two calendering rolls 4 is connected by a belt 14, so that a single motor can drive the two calendering rolls 4 to rotate for calendering through the transmission effect of the gear 13 and the belt 14, ensuring the normal operation of the calendering machine.

[0034] Working principle: The two calendering rollers 4 of this invention can ensure the normal calendering operation of thermally conductive silicone production and ensure its normal use effect.

[0035] A single motor can drive two calendering rollers 4 to rotate for calendering through the transmission effect of gear 13 and belt 14, ensuring the normal operation of the calender.

[0036] When the calender is calendering, the cooling fan 7 can blow air to cool the outside of the calendering roll 4, which can effectively help the roll body to cool down physically by blowing air. At the same time, it can reduce the heating rate of the roll body and has a certain air cooling effect. It is practical and allows the two roll bodies to be cooled down when calendering, thus improving the performance.

[0037] When the roll body overheats and needs to be cooled, the calender is stopped. The inlet connector 10 and the outlet connector 11 are connected to the water cooling system through pipes. The water tank of the water cooling system is connected to the inlet of the circulating pump through a pipe, the outlet of the circulating pump is connected to the inlet connector 10 through a pipe, and the outlet connector 11 is connected to the outlet of the water tank through a pipe. This forms a water cooling circulation system for cooling the roll body. At this time, the circulating pump of the external water cooling system circulates the coolant into the water cooling pipe 9. The circulating coolant can effectively remove the temperature of the roll body, thereby helping the roll body to undergo rapid water cooling.

[0038] In summary, this utility model, through the water-cooling pipe 9, can perform water-cooling heat exchange and cooling treatment on the inside of the calender roll 4, which has a better water-cooling heat dissipation effect. It can quickly cool down the calender roll 4 when it is overheated, thereby improving the heat dissipation speed of the calender roll 4. Compared with traditional natural cooling, this utility model, through the pipe-type water-cooling heat dissipation effect, can effectively improve the overall cooling and heat dissipation speed of the roll body, improve the use effect, and thus effectively shorten the machine downtime, improve the overall production efficiency and production speed of the calender, and has better practicality. At the same time, the spiral-shaped water-cooling pipe 9 can effectively increase the circumferential contact area with the roll body, improve the water-cooling heat exchange effect, and have a good use effect.

[0039] Furthermore, the cooling fan 7 can provide air cooling to the outside of the calendering roll 4, effectively helping the roll body to cool down physically. At the same time, it can reduce the heating rate of the roll body, providing a certain air cooling effect. It is practical and allows both roll bodies to be cooled down during calendering, improving the performance. When used in conjunction with the water cooling pipe 9, the thermally conductive silicone calendering structure of this invention has a dual cooling effect of internal water cooling and external air cooling, effectively improving the heat dissipation performance of the roll body, accelerating the cooling efficiency, and resulting in better performance.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
