摘要

功耗和热问题已成为规模技术日益严重的问题。这种现象推动了对先进冷却系统的需求。众所周知,冷却工作温度会降低电力和/或速度增益。由于冷却成本对总功率不利,因此开发了一种制冷系统并进行了实验测试,以证明冷却高性能微处理器可以导致整体系统功率的提高。使用我们的制冷系统冷却在97°C下工作的处理器,其最大功率为175.4W,电子泄漏功率为30%。测量表明,最低制冷COP为2.7,处理器在结温下运行,在整个处理器使用范围内节省总功率的13%。

Total system power minimization of microprocessors using refrigerated systems for electronic cooling
Power dissipation and thermal problems have become a growing issue for scaled technology. This phenomenon drives the need for advance cooling systems. It is well-known that cooling the operating temperature results in reduced electric power and/or speed gains. Since cooling cost penalizes the total power, a refrigeration system is developed and experimentally tested to demonstrate that cooling the high performance microprocessor can lead to overall system power improvement. A processor that dissipates 175.4W of maximum power with 30% electronic leakage power operating at 97°C is cooled using our refrigeration system. Measurements show that with a minimum refrigeration COP of 2.7, the processor operates with junction temperature <40°C and offers a 25% total system power reduction over the non-refrigerated design. This experiment is the first demonstration of active cooling that lead reduced total wall power. With an improved compressor that maintains the COP across a broad range of cooling capacity, our analysis shows that at least >13% of total power is saved across the entire range of processor utilization.
