Control for high heat chips´ cooling based on power consumption and temperature signals

For CPU chips´ cooling task, existing mono-variable control system has the defects of delay, fluctuation and high energy consumption. With the trend of multi-core and high frequency work pulse in CPU chips, traditional system does not fit for future cooling task. Several approaches such as chips´ dissipated power nonlinear feed-forward, core temperature tracking and surface temperature feed-back are applied to improve control system. Simulations prove that comparing with the traditional out-core temperature based mono-input-output proportion tracking strategy, the improved system can bring better quality and energy-saving results. Also, the new system has parameters adaptability.
