In response to the strong burning sensation in the back and hip areas experienced by passengers during prolonged sitting and high temperatures from existing vehicle air conditioning systems,which can cause discomfort,a research and design has been conducted to embed a capillary mesh cooling end in the seat cush-ion.Based on the temperature difference between the seat cushion surface and the human body,thermal ex-change is carried out to improve the surface temperature of the seat cushion.By conducting orthogonal design experiments on the seat c...
