摘要
微通道散热是近年来发展起来的一种新型散热措施。讨论了一种蜂窝状微通道散热器,并设计了基于该微通道散热器的散热系统。系统实验表明,当17 cm2的微通道散热器在系统内流体流量为13.3 ml/s时,可带走发热源约233.63 W热能,同时微通道散热器工质温度能维持在52℃左右。实验还发现,要充分发挥微通道散热器的优势,散热系统中与环境交换热量的小型换热器的散热能力也非常重要。
Heat dissipation by micro-channel heat sink provides a kind of new solution for thermal management. A kind of honeycomb micro-channel heat sink used for building a heat dissipation system is discussed. Experiments on such a system were conducted. The results demonstrate that with 13. 3 ml/s flow rate and room temperature of 32 ℃, the 17 cm^2 microchannel heat sink can take out 233.63 W heat, the corresponding heat flux of heat source is about 13.3 W/cm^2 , in such a case, the temperature of the water inside the micro-channel heat sink is just about 52 ℃. It is also found that in order to take full advantage of micro-channel heat sink, without good heat exchange between system and environment for mini heat exchanger in present system, the micro-channel heat sink can not achieve good cooling effect.
