摘　　要：热管作为高效传热元件,在CPU散热方面显示出独特的能力。对一种台式机所用的热管式CPU散热器的散热性能进行了试验研究和数值模拟。结果表明,其散热性能完全满足115 W发热量CPU的散热要求。指出单纯提高风扇的转速不能有效提高散热器及系统的整体性能。CPU散热器应使用具有调速电机的风扇。Heat pipe is a high efficient component,it reveals especial competence in the CPU exchanger. Experiment research and numerical simulation had carried on the desktop heat pipe exchanger. The result indicated that its heat dissipation performance satisfied totally the 115 W CPU＇s heat dispel request, and indicated that only improving the motor fan＇s rotate speed can＇t increase the exchanger and the system performance efficiently. The CPU exchanger should use the motor fan which may modulate velocity.
