引言 最近十年间所设计和生产的电子设备都要求解决一些电设备特有的热传导问题。热传导是一门老的科学,热传导的一些定律,基本经验,试验结果,数据以及这些定律的应用都已经200多年了。因此,在这篇短的论文里所介绍的一些公式和计算都已经证实过了,并且是以反复试验的数据为基础的。这些有效数据的值也的确在摆动着,因此选择在电子设备的热 Introduction The design and manufacture of electronic equipment in the last decade has required the resolution of some heat conduction problems specific to electrical equipment. Heat conduction is an old science, some laws of heat conduction, basic experience, test results, data and the application of these laws have been more than 200 years. Therefore, some formulas and calculations introduced in this short paper have been validated and based on trial and error. The value of these valid data is indeed swinging, so choose the heat in the electronic device
