Abstract：Objective To analyze and optimize the temperature field and flow field in the incubator. Methods The airflow in the
infant incubator was taken as the research object. Using the orthogonal test method, the factors of inlet size, outlet size, inlet
wind speed and inlet angle were selected to design 9 different combinations according to the orthogonal table. The computational
fluid dynamics method was adopted to calculate each level combination. The temperature and velocity values of 10 points
above the baby bed in the calculation area were taken, and the temperature and air velocity inhomogeneity coefficients were
calculated, which were used as the test indexes for the temperature field and flow field uniformity of the incubator. Results The
influence factors were analyzed with the range analysis. The optimal solution was as follows: the inlet size was 250 mm×14 mm, the
outlet size was 200 mm×14 mm, the inlet wind speed was 1.3 m/s, and the inlet angle was 15°. The results showed that the optimal
combination obtained by orthogonal test was effective. Conclusion The orthogonal test method is feasible for the performance
optimization of the temperature field and flow field of infant incubator.
