AB - In order to improve the thermal power dissipation of batteries and reduce the  maximum temperature difference of batteries, the air conditioning system  using battery type was optimized. Using multi-objective optimization method  based on orthogonal experiment and multiple rotations, the local optimum  values of multi-objective were obtained: the left end height A of entrance  area and the height B of air outlet were 9 mm and 28 mm, respectively, with  a tolerance value C of 0.4 mm for battery spacing. The simulation results of  this optimization model show that the maximum temperature difference of the  battery volume is 306.627 K (33.477°C) and 3.815 K (3.815°C), respectively.  Compared with the initial model, they are reduced by 9.55% and 25.89%,  respectively. Compared with the single factor analysis optimization model,  they are reduced by 0.36% and 20.27%, respectively, indicating that the  multi-objective optimization results are better. This multi-objective  programming solves the problem of different parameters of air conditioning  heat dissipation model to some extent, and can provide reference for the  optimization design of other models.
