摘要
为了实现计算机芯片散热静音、高效的目的,研制了一种新型的、以双腔并联压电泵为动力源的计算机芯片水冷散热系统,解释了双腔并联压电泵的结构及工作原理,应用流体动力学、传热学等理论阐明了水冷散热器的设计方法.采用有限元分析软件对散热器进行了热量分布仿真,通过实验的方式,测试了水冷系统内部流量及风扇对计算机芯片散热效果的影响规律.通过与现有芯片CPU Cooler系列风冷散热器的对比实验,发现该水冷系统的散热效率较高,在相同工况、加热功率60 W时,研制的集成式水冷系统所冷却的模拟芯片加热器的热平衡温度比CPU Cooler冷却时的温度低6℃,而到达热平衡的时间却缩短了35 min.
To cool computer chip silently and efficiently, a new type of computer chip water-cooling system driven by piezoelectric pump with two parallel-connected chambers is fabricated, and the mechanism and structure of piezoelectric pump with two parallel-connected chambers are described. The designing method of water-cooling radiator is proposed based on the theory of fluid dynamics and heat transfer, and a finite element simulation of heat distribution is carried out. The influences of flowrate in the cooling system and fan are experimentally explicated, It is found that the compositive water-cooling system enables to shorten 35 rain to reach lower heater steady temperatures as 6℃ than the current wind-cooling radiator at 60 W heating power level.
