Thermal Analysis Solution

Thermal Analysis Solution of Electronic Device

We can propose the solution (Optimal part mounting, countermeasure against heat dissipation, structure and of a cooling system) by using following simulation.

  • Thermal Fluid Analysis Simulation of air in the box and coolant in the Liquid-Cooling System
  • Thermal Analysis Simulation of each device
