如何计算热阻?一个整体物体(如墙壁)的热阻可以通过各层电阻来计算。无论物体有多少层,只需填写每层的厚度、面积和电阻值到表格中即可。可使用材料数据库查找特定材料的数值。所有层的面积应相同,但厚度可以不同。计算出的热阻单位为开尔文每瓦特(K/W),输入数据应以米(m)、平方米(m²)和米开尔文每瓦特(mK/W)为单位。
热阻:
Where:
R = thermal resistance
x = penetration depth or width of material
A = area
k = thermal conductivity
Notes of interest:
- This does not account for contact resistance between the different layers or components.
Effects like this should be directly measured. - Values for thickness (m) and area (m2) are entered manually. The material’s conductivity (W/mK) can be entered manually or selected from our materials database by clicking the SELECT MATERIAL button, then selecting a material from the left.
