Simulation and heat dissipation design of vehicle distribution box

Due to the limitation of vehicle space, more and more modular were integrated together, such as DC/DC and AC/DC charger were integrated in the distribution. In order to overcome excessive volume and confused layout of modular, a new multifunctional vehicle distribution box was design. The internal modules of the distribution box would affect each other and the temperature field. A few of design and improve rules were presented together with temperature field simulation. The simulation result by ANSYS showed the improvement would effectively reduce the temperature of the distribution box.
