鑲熱管鑲銅管散熱器

當(dāng)空間受限或者通風(fēng)不暢時(shí)，鑲熱管或鑲銅管散熱就成為一個很好選擇。

熱管能水平放置來解決空間高度受限而達(dá)到散熱需要。通常由于有障礙物阻擋空氣不能自由流動來冷卻設(shè)備，我們用熱管將蒸發(fā)器與遠(yuǎn)端的被阻塞通風(fēng)的冷凝器連接起來以達(dá)到冷卻效果。

銅有更好的熱導(dǎo)性，但當(dāng)鋁質(zhì)底座不能承受其重量時(shí)，用較輕的熱管來代替銅板也可以起到所需要的散熱效果。熱管也可以鑲嵌在銅質(zhì)底座里以減小質(zhì)量來達(dá)到散熱效果。

使用熱管后，不需使用電扇來散熱并能以低轉(zhuǎn)速來運(yùn)轉(zhuǎn)系統(tǒng)，這樣帶來的直接好處是能提供系統(tǒng)工作的穩(wěn)定性和降低維護(hù)費(fèi)用。相對傳統(tǒng)的散熱解決方案，在低速空氣流動情況下用熱管也能提高散熱效果。

Transport designs canbe useful where space is constrained or airflow is not available directly overthe device requiring cooling. Examples of application characteristics wheretransport heat pipes solutions may solve design issues include:

Limitedheight or space—Heat pipes can spread the cooling solution volumehorizontally rather than vertically to achieve the desired thermal performance.

Obstructedairflow—Obstructions in the chassis may leave insufficientairflow over the device to be cooled. Connecting an evaporator to a remotecondenser using a heat pipe allows the condenser to be placed in an area ofunobstructed airflow to provide the necessary cooling.

Heat pipes can be added to an aluminum base when the use of higherthermally conductive metal like copper cannot be tolerated due to weight. Heat pipes can also beembedded in copper bases to increase spreading without adding mass to thesolution.

Elimination of fans or operating them at lower RPMs canincrease system reliability and lower maintenance costs. Passive solutionsusing heat pipes may increase performance at lower airflow than withconventional thermal solutions.
