heat exchange method is the mainstream of the polycrystalline silicon ingot production methods at home and abroad. The United States, Britain, ALD and German gas company

solar and other companies are using this method. The main characteristic of this process is crucible and heater no relative displacement in the whole process of melting and solidification. Crucible workbench should be set at the bottom of a thermal switch, melt when the thermal switch should be closed, in order to have the effect of heat insulation. At the beginning of the solidification, heat switch, in order to improve the degree of cooling at the bottom of the crucible, and establish a hot field. Thermal switch, including flange, blinds, etc. Heat exchange method of the crystal growth rate is controlled by cooling intensity at the bottom of the crucible, if use water cooled by the cooling water flow rate ( And the temperature difference between inlet water and outlet water) Control. Due to the directional solidification can only be one-way heat flow ( Cooling) , radial ( The crucible lateral) Cannot heat dissipation, namely the radial temperature gradient tends to zero, the crucible and the heater is fixed, therefore, as the solidification, thermal field of the isotherm ( Above the melting point temperature) Will gradually move up, at the same time must ensure that no radial heat flux, so it is difficult to control and regulate the temperature field. When the liquid - Solid surface gradually rises, liquid - Solid interface temperature gradient must be greater than zero, but the interface is gradually increased, until temperature gradient decreases to zero. Can be seen from the above analysis, long product rate and heat exchange method of temperature gradient is different. In order to overcome the system limits the height of, only by increasing the silicon ingot area to expand capacity in Russia. Another advantage of this approach is not to need to moving parts to remove eager to break boundaries, thus protect the body structure is relatively simple, and heat exchange crystallization furnace heater can vertical and horizontal.
