「导热传热（傅里叶定律）」是什么？What is the Heat Transfer Calculator (Conduction) tool?
Q = k × A × ΔT / d：k 导热系数 W/(m·K)，A 面积，ΔT 两侧温差，d 厚度；并给出热阻 R = d/(kA)。本地处理。Q = k × A × ΔT / d: conductivity k W/(m·K), area A, temperature difference ΔT and thickness d; plus thermal resistance R = d/(kA). Processed locally.
如何使用「导热传热（傅里叶定律）」？How do I use the Heat Transfer Calculator (Conduction) tool?
在「导热传热（傅里叶定律）」中，填写「导热系数 W/(m·K)」、「面积 m²」、「温差 K」、「厚度 m」等参数，结果会随输入实时计算并显示在下方。In the Heat Transfer Calculator (Conduction): Fill in "Conductivity W/(m·K)", "Area m²", "Temperature difference K", "Thickness m"; results are recalculated instantly as you type.
对流和辐射？Convection and radiation?
本页只算固体导热；对流用 Q = hAΔT，辐射用 Q = εσA(T₁⁴ - T₂⁴)。Conduction only; convection is Q = hAΔT and radiation Q = εσA(T₁⁴ - T₂⁴).
能举个计算实例吗？Can you show a worked example?
例如在「导热传热（傅里叶定律）」中填 导热系数 W/(m·K) = 0.6，面积 m² = 10，温差 K = 20，厚度 m = 0.2，结果区显示：传热功率 Q：600 W；热流密度：60 W/m²；热阻 R：0.0333333 K/WFor example, entering Conductivity W/(m·K) = 0.6, Area m² = 10, Temperature difference K = 20, Thickness m = 0.2 in the Heat Transfer Calculator (Conduction) gives: Heat flow Q: 600 W; Heat flux: 60 W/m²; Thermal resistance R: 0.0333333 K/W
哪些输入会被检查？Which inputs are validated?
「导热传热（傅里叶定律）」会检查这些输入——「导热系数 W/(m·K)」、「面积 m²」、「厚度 m」：必须填写，须大于 0；「温差 K」：必须填写；绝对值超过 10¹⁵ 的数也会被拒绝。不符合时结果区显示具体提示，不会给出数字。The Heat Transfer Calculator (Conduction) checks its inputs — "Conductivity W/(m·K)", "Area m²", "Thickness m": required, must be greater than 0; "Temperature difference K": required; numbers above 10¹⁵ in absolute value are rejected too. When a value fails, the result area names the problem instead of showing a number.
有哪些选项可以调整？What options can I adjust?
「导热传热（傅里叶定律）」的设置：「导热系数 W/(m·K)」默认 0.6；「面积 m²」默认 10；「温差 K」默认 20；「厚度 m」默认 0.2。每次生成结果都按当前设置处理。Settings in the Heat Transfer Calculator (Conduction) — "Conductivity W/(m·K)" default 0.6; "Area m²" default 10; "Temperature difference K" default 20; "Thickness m" default 0.2. The result always uses the current settings.
计算结果可以用于作业或工程吗？Can I use the results for homework or engineering?
「导热传热（傅里叶定律）」使用教科书标准公式（公式写在说明和常见问题中），适合学习和估算核对；涉及安全的工程设计请以规范和实测为准。The Heat Transfer Calculator (Conduction) uses standard textbook formulas (given in the description and FAQ), which is good for learning and checking estimates; for safety-critical engineering follow codes and measured values.
