Abstract：If the temperature inside the reagent storehouse of the automatic biochemical analyzer did not meet its reagent storage conditions,it would result in failure of diagnostic reagents and diagnosis of error.In order to make the reagent storage room meet the requirements of medical reagent storage,the structure of the reagent storehouse was improved,and the temperature field in the reagent room was analyzed before and after the improvement.The three-dimensional nonlinear finite element model of the reagent silo was established,and the simulation was carried out by ANSYS CFX14.0,then the temperature field of the model was analyzed by applying wind speed of 0,0.5,1,4,8 m/s.The air temperature in the reagent compartment was detected at the reagent storage temperature monitoring point,and the feasibility of the optimization of the reagent compartment was explored by the finite element analysis of the temperature field.The simulation results show that,there is temperature stratification of the air in the reagent chamber of the automatic biochemical analyzer without the fan and the temperature difference is up to 8 ℃.Adding the fan can make the reagent chamber temperature control in about 4 ℃ and the temperature difference within 1 ℃.In view of the fever of the fan itself,the wind speed 1 m/s was considered to meet the design requirements of the reagent storage temperature.
