Abstract：
This paper mainly discusses the development of polycrystalline silicon reduction furnace chassis structure. In order to enhance the uniformity of chassis internal temperature field and the security of chassis structure, we improve the type of chassis internal coolant′s flow channel by introducing a new type of flow channel, which is applied for coolant distribution and limiting jet to format directly injection flow pattern. The new structure makes it more difficult to form a gas membrane compartment under the surface of chassis′ skateboard. This greatly reduces the thermal stress of the chassis skateboard and improves the security of the chassis structure. Combined with the R&D demand of a large scale polycrystalline silicon reduction furnace, the thermal analysis involved radiation, heat conduction and convection were conducted with software Fluid, using computational fluid dynamics (CFD), and the contours of the chassis internal temperature field were given. The results of the simulation could be used as the temperature boundary condition in the thermal-structure coupling analysis, which could help obtain the optimal solution of structure meeting the requirement of strength and stiffness.
