[0028] like Figure 4 As shown, the air cooling mechanism 6 includes a connecting plate 601, which is connected to the furnace body shell 1, a notch is provided on one side of the connecting plate 601, a second fixed frame 602 is inserted in the notch, a plurality of equidistant heat sinks 603 are fixedly connected to one side of the second fixed frame 602, through holes are provided on both sides of the second fixed frame 602, a cooling pipe 604 is fixedly connected in the through hole, a water pump 605 is fixedly connected at one end of the cooling pipe 604, a cooling box 606 is fixedly connected to one side of the water pump 605, the cooling box 606 is connected to the furnace body shell 1, a through hole is provided on one side of the top of the cooling box 606, a first water inlet pipe 607 is fixedly connected in the through hole, a second mounting plate 608 is fixedly connected to one side of the second fixed frame 602, and cooling fans 609 are installed on both sides of the top of the second mounting plate 608.

[0029] It should be noted that during use, the coolant is first added to the cooling box 606 through the first water inlet pipe 607, and the coolant is input into the cooling pipe 604 through the water pump 605, then the connecting plate 601 and the furnace body shell 1 are connected, and the second fixing frame 602 is inserted into the connecting plate 601.

[0032] Working principle: During use, first open the sealing door 2 and place the seed crystal on the rotating plate 406, then the servo motor 405 on the first mounting plate 403 drives the driving gear 404 to rotate while driving the driven gear 402, the rotating shaft 401 and the rotating plate 406 to rotate. In this process, the lifting motor 505 on the fixed block 503 drives the connecting rod 504 to rotate, driving the lifting gear 506 to rotate while driving the tooth plate 502 to move, so that the graphite plate 508 on the fixed plate 507 moves up and down to heat the seed crystal. When the temperature in the furnace shell 1 is high, the second fixed frame 602 is inserted into the connecting plate 601. When it is necessary to heat the seed crystal, When it is hot, the cooling fan 609 on the second mounting plate 608 starts to absorb the heat from the furnace shell 1. In this process, the heat is dissipated through the heat sink 603 and the cooling tube 604. At the same time, the twist cover 703 is manually opened to add cold water into the cold water tank 701 through the second water inlet pipe 702, and under the control of the solenoid valve 704, the cold water is input into the heat exchange tube 705 for heating. When the water temperature in the heat exchange tube 705 rises, the manual valve 706 is opened to release the hot water. Finally, the progress of the seed crystal growth is observed through the observation window 3. The device can ensure uniform temperature distribution in the entire heating area, reduce local overheating or cooling, and improve the consistency of product quality.
