Abstract: Aiming at the uniformity of temperature field of the constant temperature reactor heating system on tissue processor, the heating pad′s heating power distribution of the constant temperature reactor was studied. Firstly the established finite element model was calibrated according to the experiments in actual working condition, then the four heating pads was used as variable values to design a uniform experiment, then the finite element model combined with the uniform experiment was used to simulate uniform experiment. Genetic algorithm was used to optimize the regression equation obtained by uniform experiment optimization, then numerical simulation and test were performed in actual working condition according to the result of optimization. The results indicate that the uniformity of constant temperature reactor′s internal temperature field meet industry requirements. The results of finite element analysis coinciding basically with the experimental measurements of the temperature field in practical working conditions verify the rationality of the established finite element model.
