AI Technical Summary
During the single crystal silicon pulling process, the traditional non-contact heat dissipation method limits the pulling speed, and the contact heat dissipation solution may affect the movement stability of the crystal rod, resulting in unstable pulling or wire breakage.
A motor was designed with a hollow channel along the central axis and cooling structures set on the side walls and ends. Combined with a rotating mechanism and heat dissipation tooling, contact heat dissipation of the crystal ingot was achieved while maintaining the movement stability of the crystal ingot.
Through contact heat dissipation, the limitations of traditional heat dissipation levels are broken, the crystal pulling speed is increased, the production cost is reduced, and the risk of crystal breaking is reduced.
