| 摘 要： | 为了研究电机机壳外肋的各因素组合方式对系统散热性能的影响,采用综合的正交试验法,以机壳的最高温度为指标,通过正交试验极差分析法分析得知肋间距是最敏感的影响因素,其次是肋厚,再次是肋高.随着肋高的增大,最高温度先降低后升高;随着肋宽的增大,最高温度先降低后升高;随着肋间距的增加,最高温度逐渐升高,升高斜率越来越低.综合考...

| Abstract: | The orthogonal experiment method was adopted to study the influence of the geometric parameters of the fins around the motor shell on the overall heat dissipation performance of the motor. The study showed that the key factors that influence the maximal temperature in the motor shell are,respectively,the fin pitch,the fin thickness and the fin height with their sensitivities decreasing in sequence.It was found that with the increase in the fin thickness or the fin height,the maximum shell temperature decrea... |
