Description

Technical Field

[0001] This invention relates to the field of graphite boat technology, specifically to a graphite boat insert heat dissipation device. Background Technology

[0002] A graphite boat is essentially a graphite mold, a carrier in which raw materials and components that need to be positioned or shaped are placed and sintered at high temperatures. Graphite molds are made from artificial graphite through machining, hence they are sometimes called graphite boats or graphite ships.

[0003] In the production process of crystalline silicon solar cells, graphite boats transport the wafers from an environment of 700 to 800 degrees Celsius to a dedicated semi-enclosed heat dissipation device. Traditional heat dissipation devices are semi-enclosed spaces with only a few ventilation holes at the bottom to prevent the wafers from being contaminated by factory debris. In addition, there is a tray under the wafers in the heat dissipation device, with a fan installed above the tray and water pipes below the fan. The device uses air cooling to blow hot air onto the water pipes, heating the water. Then, through water circulation, the hot water is carried away and cold water is brought in, thus achieving a dual heat dissipation effect of air cooling and water cooling. However, the heat dissipation efficiency of existing heat dissipation devices is too low. To address this, we have provided a graphite boat wafer heat dissipation device. Summary of the Invention

A wall is provided on one side of the support frame. A cooling rack is installed on the inner surface of the cooling chamber above the cooling platform.

[0011] Preferably, the lower part of the cooling nozzle is fixedly connected to a flexible hose, the lower part of the flexible hose is fixedly connected to a diverter pipe, and the left end of the diverter pipe is located below the inner surface of the cooling platform.

[0012] Preferably, a through-hole cavity is provided below the cooling nozzle, a solenoid valve is installed at the right end of the diverter pipe, and the right end of the diverter pipe is fixedly connected to the pressure tank.

[0013] Preferably, a filter ball is provided below the water tank, and the filter ball is fixedly connected to the water pump.

[0015] Preferably, protective nets are fixedly connected to both the upper and lower parts of the side shell, and a liquid level window is provided on the outer surface of the water tank.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The air compressor and pressure tank store high-pressure air into the pressure tank, resulting in a large amount of compressed air stored inside the pressure tank. Then, with the help of the cooling platform and the swing jet assembly, the large amount of compressed air is jetted out in a high-pressure form. The high-velocity airflow can remove a lot of heat from the graphite boat in a short time, reducing the cooling time. At the same time, multiple graphite boats are cooled together to reduce the cooling time of a single graphite boat, thus achieving a faster and more efficient heat dissipation method.

[0018] 2. The oscillating jet assembly is driven by a motor to rotate the gearbox and crank, which in turn drives the ring, short rod, long rod, and rack to reciprocate. The rack then drives the gear and cooling nozzle to oscillate periodically. In conjunction with the diverter pipe, high-pressure airflow is input from the pressure tank, allowing the high-pressure air to periodically and repeatedly dissipate heat from the graphite boat. By repeatedly oscillating the nozzle, the high-pressure airflow can uniformly cool the entire graphite boat, avoiding insufficient airflow in some areas of the graphite boat, which would result in inconsistent cooling rates.

[0019] 3. The circulating cooling component uses a water pump to drive the coolant in the water tank to flow along the pressure-resistant hot water pipe. Due to the increased internal energy of the compressed air, the coolant flowing through the pressure tank quickly transfers the heat from the compressed air inside the pressure tank. The heat-conducting rod and heat sink then transfer the heat transferred to the coolant, which is cooled by the fan blowing on the heat sink. This effectively reduces the heat of the compressed air inside the pressure tank. When the compressed air is jetted, it changes from a high-pressure state to a low-pressure state, which reduces the internal energy of the air. This results in a lower temperature of the compressed air jetting above the cooling platform, allowing it to carry away more heat and thus improving cooling efficiency. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the technical solutions of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1-3This invention provides a technical solution: a graphite boat finned heat dissipation device, comprising a cooling chamber 1, a swing jet assembly 3, a pressure tank 4, and a circulating cooling assembly 5. A cooling platform 2 is fixedly connected to the lower inner surface of the cooling chamber 1, and the swing jet assembly 3 is installed on the inner surface of the cooling platform 2. The swing jet assembly 3 further includes a motor 31, a gearbox 32, a crank 33, a ring 34, a short rod 35, a long rod 36, a rack 37, a gear 38, a cooling nozzle 39, and a distributor pipe 310. One end of the motor 31 is fixedly connected to the gearbox 32, and the lower part of the gearbox 32 is fixedly connected to the crank 33. The outer surface of the middle section of the cooling chamber 1 is slidably connected to the ring 34. The right end of the outer surface of the ring 34 is fixedly connected to the left end of the short rod 35. The right end of the short rod 35 is rotatably connected to the left end of the long rod 36. The upper part of the outer surface of the long rod 36 is fixedly connected to six evenly distributed racks 37. The outer surface of the racks 37 is rotatably connected to the gear 38. A cooling nozzle 39 is provided on one side of the middle part of the outer surface of the gear 38. A diversion pipe 310 is provided below the cooling nozzle 39. A pressure tank 4 is provided on the lower right side of the outer surface of the cooling chamber 1. A circulating cooling assembly 5 is installed on the right side of the pressure tank 4. The circulating cooling assembly 5 also includes a water tank 51, a water pump 52, and a pressure-resistant hot water pipe 5. 3. Side shell 54, fan 55, heat sink 56, heat conduction rod 57. A water pump 52 is installed below the inner surface of the water tank 51. The lower left side of the water pump 52 is fixedly connected to the pressure-resistant hot water pipe 53. The right side of the outer surface of the water tank 51 is fixedly connected to the side shell 54. A fan 55 is installed below the side shell 54. A heat sink 56 is installed above the fan 55. The left side of the heat sink 56 is fixedly connected to the heat conduction rod 57. A support frame 6 is provided on the outer surface of the pressure tank 4. An air compressor 7 is installed on the support frame 6. The outer surface of the air compressor 7 is fixedly connected to the pressure tank 4 through an air supply pipe 8. A wall 9 is provided on one side of the support frame 6. A cooling rack 10 is installed on the inner surface of the cooling chamber 1 above the cooling platform 2. A graphite boat 11 is placed above the cooling rack 10. High-pressure air is stored in the pressure tank 4 by the air compressor 7, so that the pressure tank 4 stores a large amount of compressed air. Then, with the help of the cooling platform 2 and the swing jet assembly 3, the large amount of compressed air is jetted out in a high-pressure form. By using the high-speed airflow, a lot of heat on the graphite boat 11 can be removed in a short time, reducing the cooling time. At the same time, multiple graphite boats 11 are used for cooling at the same time, reducing the cooling time of a single graphite boat 11, thereby achieving a faster and more efficient heat dissipation method.

[0027] The motor 31 drives the gearbox 32 and crank 33 to rotate, which in turn drives the ring 34, short rod 35, long rod 36 and rack 37 to reciprocate. The rack 37 then drives the gear 38 and cooling nozzle 39 to oscillate periodically. In conjunction with the diverter pipe, high-pressure airflow is input from the pressure tank 4, so that the high-pressure air can periodically and repeatedly dissipate heat from the graphite boat 11. By repeatedly oscillating the cooling nozzle 39, the high-pressure airflow can uniformly cool the graphite boat 11 as a whole, avoiding insufficient airflow in some areas of the graphite boat 11, which would result in inconsistent heat dissipation speed.

[0028] The crank 33 is reinforced by the reinforcing sleeve 301, making the crank 33 structurally stable and able to withstand more movement and force. The gear 38 is not directly connected to the cooling nozzle 39, but is connected to the cooling nozzle 39 through the collar 302. The cooling nozzle 39 and the collar 302 are detachable, making it easy to replace parts. The flexible hose 303 ensures that the swing of the cooling nozzle 39 will not affect the diversion pipe 310. The diversion pipe 310 supplies high-pressure cooling airflow to multiple cooling nozzles 39. If debris falls from above the cooling nozzle 39, it will fall directly through the through hole cavity 304 and will not accumulate in the structure. It may also serve as an exhaust port. The solenoid valve 305 is used to control whether the pressure tank 4 exhausts air.

[0029] The coolant in the water tank is driven by the water pump 52 to flow along the pressure-resistant hot water pipe 53. Due to the increased internal energy of the compressed air, the coolant flowing through the pressure tank 4 quickly transfers the heat of the compressed air inside the pressure tank 4. The heat-conducting rod 57 and the heat sink 56 then transfer the heat transferred to the coolant. The fan 55 blows the heat sink 56 to cool it, thereby effectively reducing the heat of the compressed air inside the pressure tank 4. When the compressed air is sprayed, it will change from a high-pressure state to a low-pressure state. At this time, the internal energy of the air will decrease. This will make the temperature of the compressed air sprayed above the cooling platform 2 even lower, and it can carry away more heat, thereby improving the cooling efficiency.

[0030] The filter ball 501 below the water tank 51 prevents impurities from entering the pressure-resistant hot water pipe 53 for a long time, thus preventing blockage and reducing flow rate, and ensuring long-term stable operation. Support rods 502 are provided on the upper and lower left sides of the pressure-resistant hot water pipe 53, and both ends of the support rods 502 are fixedly connected to the inner surface of the pressure tank 4. Both ends of the pressure-resistant hot water pipe 53 are fixedly connected to the water tank 51, assisting and supporting the pressure-resistant hot water pipe 53, while also increasing the contact area with compressed air. The pressure-resistant hot water pipe 53 is more suitable for installation before welding the ends of the pressure tank 4. Furthermore, protective nets 503 are fixedly connected to the upper and lower sides of the side shell 54, and a liquid level window 504 is provided on the outer surface of the water tank 51. The protective nets 503 serve a protective function to prevent foreign objects from entering, while the liquid level window 504 prevents coolant loss during long-term use without the worker's notice. The compressed air cooling and then releasing the absorbed heat effect in this application is the same as the principle of air conditioners and refrigerators.
