But when the wind - speed becomes above 1m / s hereafter , wind - speed increase for the cpu thermal siphon of transmit heat the ability ' s gain result the deceleration . so it is considered perfect when the wind - speed is 1m / s . through this experimentation we found that when the cpu thermal syphon cooling machine used acetone as working fluid , wind - speed 1m / s , cpu chip caloricty 60w , its volumetric heat release rate came to 1 . 3 104w / ( m3k ) 通过本次实验测出所使用的cpu重力热管散热器在使用丙酮为工质，风速1m / s ， cpu芯片发热量为60w时，其体积散热率达到1 . 3 104w / ( m3k ) ,能保证芯片温度与环境温度之差小于40 ，能很好的适应pentium -计算机长期运行的要求。
