Heating furnace design for the thermal analysis instrument based on TRIZ theory

The furnace structure characteristics of new precision thermal analysis instruments are analyzed by applying the TRIZ theory analysis. The main affecting factors of the distribution of uniform temperature for the furnace body are obtained by using the conflict matrix. The existing conflicts are stud- ied and analyzed between the size of original oven cavity space and the resistance wire heating. Using ARIZ theory of inventive problem solving algorithm and combining with the error of experimental data for specific body of uniform temperature distribution curves of heating, two innovative designs are obtained to improve the instruments precision. Results show that the using of TRIZ theory on the design method can effectively increase the area of uniform temperature distribution and reduces the size of oven cavity temperature, which resolves the precise thermal analysis of the inner cavity of uniform temperature furnace design requirements and achieves the precise temperature control of the instrument requirements.
