[0002] Low thermal resistance thermal conductive materials play a crucial role in many fields such as modern electronics, new energy, and aerospace. For example, in electronic devices, with the continuous improvement of chip integration and power density, the amount of heat generated increases dramatically. In order to ensure the stable operation of electronic devices and extend their service life, efficient heat dissipation solutions are needed. Low thermal resistance thermal conductive materials can quickly conduct heat away, playing a good heat dissipation role.

[0025] 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.
[0026] Please see Figure 1-6 The present invention provides the following technical solution:
[0027] A rapid preheating production device for low thermal resistance thermally conductive materials includes an outer casing 1, an inner casing 2 fixedly connected to the inner side of the outer casing 1, a preheating mechanism 3 fixedly connected to the inner side of the inner casing 2, and a cleaning mechanism 4 fixedly connected to the surface of the preheating mechanism 3.
[0028] The cleaning mechanism 4 includes a connecting ring 401, a nozzle 402, two water inlet pipes 403, a diversion pipe 404, a pressurizing pump 405, and a connecting pipe 406. The inner side of the connecting ring 401 is rotatably connected to the surface of the preheating mechanism 3, and the surface of the connecting ring 401 is fixedly connected to the inner wall of the preheating mechanism 3. The nozzle 402 is fixedly connected to the surface of the connecting ring 401. The water inlet pipe 403 is fixedly connected to the top of the connecting ring 401, and the top of the water inlet pipe 403 passes through the preheating mechanism 3 and is fixedly connected to the top of the preheating mechanism 3. The diversion pipe 404 is fixedly connected to the top of the water inlet pipe 403. The pressurizing pump 405 is fixedly connected to the rear side of the outer casing 1, the rear side of the diversion pipe 404 is fixedly connected to the top of the pressurizing pump 405, and the connecting pipe 406 is fixedly connected to the bottom of the pressurizing pump 405.
[0029] In this embodiment: the outer casing 1 supports and limits the inner casing 2 and the cleaning mechanism 4. The inner casing 2 is fixed inside the outer casing 1, forming a double-layer structure that provides insulation and heat preservation, reduces heat loss, improves energy efficiency, and helps maintain stable internal temperature during preheating. It also supports and limits the preheating mechanism 3. The connecting ring 401 provides support for subsequent cleaning water distribution and delivery, and supports and limits the nozzle 402 and the water inlet pipe 403. The nozzle 402 can spray water at a certain pressure and angle onto various parts of the inner wall of the preheating tank 301, achieving cleaning of the preheating tank. The multi-angle, all-around rinsing of the inner wall of 301 effectively removes the residue of the thermal conductive gel. The water inlet pipe 403 introduces cleaning water into the connecting ring 401, providing a water source channel for the cleaning work. The diversion pipe 404 can evenly distribute the water delivered from the pressure pump 405 into the two water inlet pipes 403, ensuring that each nozzle 402 can obtain sufficient water, making the cleaning process more uniform and effective. The pressure pump 405 can pressurize the cleaning water, causing the water to be sprayed out of the nozzle 402 at a greater pressure. The connecting pipe 406 can connect the external water source to the pressure pump 405, providing a stable water supply for the entire cleaning mechanism 4, ensuring the continuous operation of the cleaning work.
[0030] Specifically, such as Figure 5 , Figure 6 As shown, the preheating mechanism 3 includes a preheating tank 301, a servo motor 302, a rotating rod 303, three stirring blades 304, a discharge pipe 305, a single-way valve 306, a feeding pipe 307, five heating plates 308, several heat-conducting rods 309, and a paraffin block 310. The preheating tank 301 is fixedly connected to both sides of the inner side of the inner box 2, and the top of the water inlet pipe 403 passes through the preheating tank 301 and is fixedly connected to the top of the preheating tank 301.
[0031] Specifically, such as Figure 5 , Figure 6 As shown, the servo motor 302 is fixedly connected to the top of the preheating tank 301, the rotating rod 303 is rotatably connected to the inner side of the preheating tank 301, the inner side of the connecting ring 401 is rotatably connected to the top of the surface of the rotating rod 303, the output end of the bottom of the servo motor 302 passes through the preheating tank 301 and is fixedly connected to the top of the rotating rod 303, and the stirring blade 304 is fixedly connected to the surface of the rotating rod 303.
[0032] Specifically, such as Figure 5 , Figure 6As shown, the discharge pipe 305 is fixedly connected to the bottom of the preheating tank 301. The front side of the discharge pipe 305 passes through the inner box 2, the bottom heating plate 308 and the outer box 1 respectively and extends to the outside of the outer box 1. The single-way valve 306 is fixedly connected to the front side of the discharge pipe 305. The feeding pipe 307 is fixedly connected to the left side of the left preheating tank 301 and the right side of the right preheating tank 301 respectively. The heating plate 308 is fixedly connected to the surface of the inner box 2. The heat-conducting rod 309 is fixedly connected to the surface of the heating plate 308. The side of the heat-conducting rod 309 away from the heating plate 308 passes through the inner box 2 and extends to the inside of the inner box 2. The paraffin block 310 is placed inside the inner box 2.
[0033] In this embodiment: The preheating tank 301 provides a relatively enclosed space for the material, which is beneficial for heat concentration and retention, improving the preheating effect. The servo motor 302 controls the rotation speed and direction of the rotating rod 303, providing power for the rotation of the stirring blade 304. Stirring ensures more uniform heating of the material, avoiding localized overheating or undercooling, and guaranteeing stable material performance. Driven by the servo motor 302, the rotating rod 303 rotates, simultaneously driving the stirring blade 304 to stir the material in the preheating tank 301, promoting mixing and heat transfer. The stirring blade 304 thoroughly stirs the low thermal resistance heat-conducting material in the preheating tank 301, allowing the material to continuously flow and mix within the tank, ensuring that all parts of the material are evenly exposed to heat, improving the uniformity and efficiency of preheating. After preheating, the discharge pipe 305 discharges the preheated material from the preheating tank 301, facilitating subsequent production processes and ensuring the smooth operation of the production process. Continuity is ensured by the single-way valve 306, which controls the opening and closing of the discharge pipe 305 to ensure that the preheated material is discharged at the appropriate time. The feeding pipe 307 facilitates the addition of low thermal resistance heat-conducting material to the preheating tank 301 by the operator, providing a convenient channel for the feeding process and ensuring normal production. The heating plate 308 generates heat when energized, providing a heat source for the material in the preheating tank 301, enabling the material to heat up quickly. The heat-conducting rod 309 can quickly conduct the heat generated by the heating plate 308 to the interior of the inner box 2, and then to the preheating tank 301 and the material inside, improving heat transfer efficiency and enabling the material to reach the preheating temperature more quickly. During the heating process, the paraffin block 310 absorbs heat and undergoes a phase change, accelerating the rate of temperature rise inside the inner box 2. The paraffin block 310 can absorb heat during the heating process and release heat during heat dissipation, avoiding excessive temperature fluctuations that could affect the material properties.
[0034] Specifically, such as Figure 5 As shown, a stopper 5 is snapped into the inner side of the top of the feeding tube 307, and the surface of the stopper 5 is engraved with anti-slip texture.
[0035] Specifically, such as Figure 3As shown, a heat insulation board 6 is fixedly connected to the inner side of the outer casing 1. The heat insulation board 6 is made of polyurethane foam material.
[0036] In this embodiment: by setting a stopper 5, the feeding pipe 307 is closed when no feeding operation is performed, preventing external dust, impurities, etc. from entering the preheating tank 301. By setting anti-slip texture, the friction between the stopper 5 and the operator's hand is increased, making it more convenient and effortless for the operator to open or close the stopper 5, and less likely to slip. By setting a heat insulation plate 6, the heat inside the inner box 2 can be effectively prevented from losing heat to the outside, reducing energy waste and improving the heat preservation effect of the device. The heat insulation plate 6 is made of polyurethane foam material, which has good heat insulation performance and can effectively prevent the heat inside the inner box 2 from losing heat to the outside.
[0037] Specifically, such as Figure 2 As shown, a lid 7 is rotatably connected to the top of the outer casing 1, and handles 8 are fixedly connected to both sides of the top of the lid 7.
[0038] Specifically, such as Figure 2 As shown, a reinforcing base 9 is fixedly connected to the front side of the pressure pump 405, and the side of the reinforcing base 9 away from the pressure pump 405 is fixedly connected to the rear side of the outer casing 1.
[0039] In this embodiment: by setting the cover 7, the outer casing 1 can be opened or closed when needed, which facilitates the operator to inspect, maintain and clean the internal preheating mechanism 3, cleaning mechanism 4 and other operations. When the device is running, closing the cover 7 can prevent heat loss and the entry of external debris, ensuring the normal operation of the device. By setting the handle 8, the operator is provided with a point of leverage to open and close the cover 7, making the operation easier and more convenient. By setting the reinforcing seat 9, the installation stability of the pressure pump 405 is enhanced, preventing the pressure pump 405 from loosening or shifting due to vibration or other reasons during operation.
[0040] Working Principle: First, the operator installs the outer casing 1 to the designated working position. Then, the operator connects the external water source to the connecting pipe 406. After connection, the operator holds the handle 8 on the casing 7 and lifts the casing 7. Next, the operator separates the stopper 5 from the feeding pipe 307. Then, the operator adds the heat-conducting material to be preheated into the two preheating tanks 301 through the feeding pipe 307. After the material is added, the operator reattaches the stopper 5 to the feeding pipe 307 to close it. Afterward, the operator powers on and starts the heating plate 308. Once the heating plate 308 starts working, the operator again uses the handle 8 to close the casing 7 to the outer casing 1, forming... In a relatively enclosed space to minimize heat loss, the heat generated by the heating plate 308 is rapidly transferred to the interior of the inner chamber 2 via the heat-conducting rod 309. The paraffin block 310 and the two preheating tanks 301 in the inner chamber 2 simultaneously absorb heat. After absorbing heat, the preheating tanks 301 uniformly heat the internal heat-conducting material. Meanwhile, the paraffin block 310 undergoes a phase change during heat absorption, acting as a buffer and temperature regulator to prevent the temperature inside the inner chamber 2 from rising too quickly. Next, the operator powers on and starts the servo motor 302. The servo motor 302 drives the rotating rod 303 to rotate, which in turn simultaneously drives the stirring blade 304 to rotate. The stirring blade 304 stirs the heat-conducting material inside the preheating tank 301. The material is thoroughly stirred to ensure continuous tumbling within the container. Once heating is complete, the operator shuts off the servo motor 302 and heating plate 308. The stirring blade 304 stops rotating, and the heating plate 308 ceases supplying heat to the inner chamber 2. At this point, the paraffin block 310, which had previously absorbed a large amount of heat, begins to release heat, maintaining the temperature inside the inner chamber 2 and effectively preventing a rapid temperature drop, thus avoiding adverse effects on material properties due to excessive temperature fluctuations. Subsequently, the operator opens the single-way valve 306, and the preheated material is discharged through the discharge pipe 305 under gravity. The operator uses external collection equipment to properly collect the discharged material. Once all the heat-conducting material has been discharged… After the water is discharged, the operator powers on the pressurizing pump 405. The pressurizing pump 405 draws external water through the connecting pipe 406 and pressurizes it. The pressurized water is guided to the connecting ring 401 through the diversion pipe 404 and the inlet pipe 403. The connecting ring 401 distributes the water to each nozzle 402. The nozzles 402 then spray the pressurized water onto the inner wall of the preheating tank 301 at a certain pressure and angle to clean the tank wall in all directions. Finally, when the inner wall of the preheating tank 301 is cleaned, the operator turns off the pressurizing pump 405 and the single-way valve 306, and opens the tank cover 7 by holding the handle 8 again. The above operation process is repeated to continue adding the heat-conducting material that needs to be heated into the preheating tank 301 to achieve continuous operation of the device.
[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
