材料的導(dǎo)熱常用材料的導(dǎo)熱系數(shù)表2優(yōu)質(zhì)資料(可以直接使用，可編輯優(yōu)質(zhì)資料，歡迎下載）傅力葉方程式：Q=KA△T/d,R=A△T/Q

Q:熱量，W；K:導(dǎo)熱率，W/mk；A：接觸面積；d:熱量傳遞距離；△T：溫度差；R:熱阻值導(dǎo)熱率K是材料本身的固有性能參數(shù)，用于描述材料的導(dǎo)熱能力。這個特性跟材料本身的大小、形狀、厚度都是沒有關(guān)系的，只是跟材料本身的成分有關(guān)系。所以同類材料的導(dǎo)熱率都是一樣的，并不會因為厚度不一樣而變化。將上面兩個公式合并，可以得到K=d/R。因為K值是不變的，可以看得出熱阻R值，同材料厚度d是成正比的。也就說材料越厚，熱阻越大。但如果仔細看一些導(dǎo)熱材料的資料，會發(fā)現(xiàn)很多導(dǎo)熱材料的熱阻值R，同厚度d并不是完全成正比關(guān)系。這是因為導(dǎo)熱材料大都不是單一成分組成，相應(yīng)會有非線性變化。厚度增加，熱阻值一定會增大，但不一定是完全成正比的線性關(guān)系，可能是更陡的曲線關(guān)系。根據(jù)R=A△T/Q這個公式，理論上來講就能測試并計算出一個材料的熱阻值R。但是這個公式只是一個最基本的理想化的公式，他設(shè)定的條件是：接觸面是完全光滑和平整的，所有熱量全部通過熱傳導(dǎo)的方式經(jīng)過材料，并達到另一端。實際這是不可能的條件。所以測試并計算出來的熱阻值并不完全是材料本身的熱阻值，應(yīng)該是材料本身的熱阻值+所謂接觸面熱阻值。因為接觸面的平整度、光滑或者粗糙、以及安裝緊固的壓力大小不同，就會產(chǎn)生不同的接觸面熱阻值，也會得出不同的總熱阻值。所以國際上流行會認(rèn)可設(shè)定一種標(biāo)準(zhǔn)的測試方法和條件，就是在資料上經(jīng)常會看到的ASTMD5470。這個測試方法會說明進行熱阻測試時候，選用多大的接觸面積A，多大的熱量值Q，以及施加到接觸面的壓力數(shù)值。大家都使用同樣的方法來測試不同的材料，而得出的結(jié)果，才有相比較的意義。通過測試得出的熱阻R值，并不完全是真實的熱阻值。物理科學(xué)就是這樣，很多參數(shù)是無法真正的量化的，只是一個“模糊”的數(shù)學(xué)概念。通過這樣的“模糊”數(shù)據(jù)，人們可以將一些數(shù)據(jù)量化，而用于實際應(yīng)用。此處所說的“模糊”是數(shù)學(xué)術(shù)語，“模糊”表示最為接近真實的近似。而同樣道理，根據(jù)熱阻值以及厚度，再計算出來的導(dǎo)熱率K值，也并不完全是真正的導(dǎo)熱率值。傅力葉方程式，是一個完全理想化的公式。我們可用來理解導(dǎo)熱材料的原理。但實際應(yīng)用、熱阻計算是復(fù)雜的數(shù)學(xué)模型，會有很多的修正公式，來完善所有的環(huán)節(jié)可能出現(xiàn)的問題?？傊篴.同樣的材料，導(dǎo)熱率是一個不變的數(shù)值，熱阻值是會隨厚度發(fā)生變化的。b.同樣的材料，厚度越大，可簡單理解為熱量通過材料傳遞出去要走的路程越多，所耗的時間也越多，效能也越差。c.對于導(dǎo)熱材料，選用合適的導(dǎo)熱率、厚度是對性能有很大關(guān)系的。選擇導(dǎo)熱率很高的材料，但是厚度很大，也是性能不夠好的。最理想的選擇是：導(dǎo)熱率高、厚度薄，完美的接觸壓力保證最好的界面接觸。d、使用什么導(dǎo)熱材料給客戶，理論上來講是很困難的一件事情。很難真正的通過一些簡單的數(shù)據(jù)，來準(zhǔn)確計算出選用何種材料合適。更多的是靠測試和對比，還有經(jīng)驗。測試能達到產(chǎn)品要求的理想效果，就是最為合適的材料。e、不專業(yè)的用戶，會關(guān)注材料的導(dǎo)熱率；專業(yè)的用戶，會關(guān)注材料的熱阻值。常用材料的導(dǎo)熱系數(shù)表用途材料名稱密度(kg/m3)導(dǎo)熱系數(shù)(W/m.K)窗框銅8900380硅合金鋁2800160黃銅8400120鐵780050不銹鋼790017PVC13900.17硬木7000.18建筑構(gòu)件軟木5000.13UP樹脂玻璃鋼19000.4玻璃碳酸鈣玻璃25001.0有機玻璃PMMA11800.18聚碳酸脂12000.2熱斷橋聚冼氨尼龍11500.256.6%尼龍,25%玻璃纖維14500.3高密度聚乙烯HD9800.5低密度聚乙烯LD9200.33固體聚丙烯9100.2225%玻纖聚丙烯12000.25聚亞氨脂樹脂PU12000.25剛性PVC13900.17防雨氯丁橡膠PCP12400.23密封條三元乙丙EPDM11500.25純硅膠12000.35柔性PVC12000.14聚脂馬海毛0.14柔性橡膠泡末60-800.05密封劑剛性聚氨脂PU12000.25固體/熱融異丁烯12000.24聚硫膠17000.4純硅膠12000.35聚異丁烯9300.2聚脂樹脂14000.19硅膠干燥劑7200.13分子篩650-7500.1低密度硅膠泡末7500.12中密度硅膠泡末8200.17金屬導(dǎo)熱系數(shù)表（W/mK)熱傳導(dǎo)系數(shù)的定義為：每單位長度、每K，可以傳送多少W的能量，單位為W/mK。其中“W”指熱功率單位，“m”代表長度單位米，而“K”為絕對溫度單位。該數(shù)值越大說明導(dǎo)熱性能越好。以下是幾種常見金屬的熱傳導(dǎo)系數(shù)表：銀429銅401金317鋁237鐵80錫67鉛34.8各種物質(zhì)導(dǎo)熱系數(shù)！materialconductivityK(W/m.K)diamond鉆石2300silver銀429cooper銅401gold金317aluminum鋁237各物質(zhì)的導(dǎo)熱系數(shù)物質(zhì)溫度導(dǎo)熱系數(shù)物質(zhì)溫度導(dǎo)熱系數(shù)亞麻布500.09落葉松木00.13木屑500.05普通松木450.08～0.11海砂200.03楊木1000.1研碎軟木200.04膠合板00.125壓縮軟木200.07纖維素00.46聚苯乙烯1000.08絲200.04～0.05硫化橡膠500.22～0.29爐渣500.84鎳鋁錳合金032.7硬質(zhì)膠250.18青銅3032～153白樺木300.15殷鋼3011橡木200.17康銅3020.9雪松00.095黃銅2070～183柏木200.1鎳鉻合金2012.3～171普通冕玻璃201石棉00.16～0.37石英玻璃41.46紙120.06～0.13燧石玻璃320.795皮棉4.10.03重燧石玻璃12.50.78礦渣棉00.05～0.14精制玻璃120.9氈0.04汽油120.11蠟0.04凡士林120.184紙板0.14“天然氣”油120.14皮革0.18～0.19甘油00.276冰2.22煤油1000.12新下的雪0.1蓖麻油5000.18填實了的雪0.21橄欖油00.165瓷1.05已烷00.152石蠟油0.123二氯乙烷0.147變壓器油0.12890%硫酸0.354石油0.14醋酸18石蠟0.12硝基苯0.159柴油機燃油0.12二硫化碳0.144瀝青0.699甲醇0.207玄武巖2.177四氯化碳0.106拌石水泥1.5三氯甲烷0.121花崗石2.68～3.35氨氣*0.022丙銅0.177水蒸汽*0.0235～0.025苯0.139重水蒸汽*0.072水0.54空氣*0.024重水0.559硫化氫*0.013表2窗體材料導(dǎo)熱系數(shù)窗框材料鋼材鋁合金PVCPA松木導(dǎo)熱系數(shù)58.22030.160.230.17表3不同玻璃的傳熱系數(shù)玻璃類型玻璃結(jié)構(gòu)(m)傳熱系數(shù)K-w/(m2-k)單層玻璃6.2雙層中空玻璃5×9×53.265×12×53.11一層中空玻璃5×9×5×9×52.22←--5×12×5×12×52.08Lhw-E中空玻璃5×12×51.71常用材料導(dǎo)熱系數(shù)--深圳智通電子提供MetalMaterialConductivityDensityW/m-Ckg/m3Aluminum,2024,Temper-T31212.80E+03Aluminum,2024,Temper-T3511432.80E+03Aluminum,2024,Temper-T41212.80E+03Aluminum,5052,Temper-H321382.68E+03Aluminum,5052,Temper-O1442.69E+03Aluminum,6061,Temper-O1802.71E+03Aluminum,6061,Temper-T41542.71E+03Aluminum,6061,Temper-T61672.71E+03Aluminum,7075,Temper-O1302.80E+03Aluminum,7075,Temper-T61302.80E+03Aluminum,A356,Temper-T61282.76E+03Aluminum,Al-Cu,Duralumin,95%Al-5%Cu1642.79E+03Aluminum,Al-Mg-Si,97%Al-1%Mg-1%Si-1%Mn1772.71E+03Aluminum,Al-Si,Alusil,80%Al-20%Si1612.63E+03Aluminum,Al-Si,Silumim,86.5%Al-1%Cu1372.66E+03Aluminum,Pure2202.71E+03Beryllium,Pure1751.85E+03Brass,Red,85%Cu-15%Zn1518.80E+03Brass,Yellow,65%Cu-35%Zn1198.80E+03Copper,Alloy,110003888.93E+03Copper,Aluminumbronze,95%Cu-5%Al838.67E+03Copper,Brass,70%Cu-30%Zn1118.52E+03Copper,Bronze,75%Cu-25%Sn268.67E+03Copper,Constantan,60%Cu-40%Ni22.78.92E+03Copper,DrawnWire2878.80E+03Copper,Germansilver,62%Cu-15%Ni-22%Zn24.98.62E+03Copper,Pure3868.95E+03Copper,Redbrass,85%Cu-9%Sn-6%Zn618.71E+03Gold,Pure3181.89E+04Invar,64%Fe-35%Ni13.88.13E+03Iron,Cast557.92E+03Iron,Pure71.87.90E+03Iron,Wrought,0.5%C597.85E+03Kovar,54%Fe-29%Ni-17%Co16.38.36E+03Lead,Pure351.14E+04Magnesium,Mg-Al,Electrolytic,8%Al-2%Zn661.81E+03Magnesium,Pure1711.75E+03Molybdenum1301.02E+04Nichrome,80%Ni-20%Cr128.40E+03Nickel,Ni-Cr,80%Ni-20%Cr12.68.31E+03Nickel,Ni-Cr,90%Ni-10%Cr178.67E+03Nickel,Pure998.91E+03Silver,Pure4181.05E+04Solder,Hard,80%Au-20%Sn571.50E+04Solder,Hard,88%Au-12%Ge881.50E+04Solder,Hard,95%Au-3%Si941.57E+04Solder,Soft,60%Sn-40%Pb509.29E+03Sold
