heat pipe 設計原理及制造

熱管(HEAT

PIPE)設計簡介熱管簡介 熱管是利用作動流體的相變化，達到微小溫差，快速傳送大量熱量的元件，即為所謂的熱超導。

1.無需外接電源

2.熱傳速率快

3.結構簡單重量輕

4.可靠性高

5.無噪音

6.無需保養(yǎng)維修熱管的基本結構1.密閉容器:

鋼，鋁，銅…等。2.毛細構造:

銅網(wǎng)，溝槽，燒結，纖維。3.作動流體:

水，甲醇，丙酮….等。MeshGroovePowderFiber熱管作動原理熱管是利用作動流體的相變化產(chǎn)生(加熱端)，使熱立即傳輸至另一端(冷卻端)，再借由毛細結構，由冷卻端拉回加熱端並達到連續(xù)進行熱輸送。QinQoutTHighTLow熱管特性1.導熱性高2.均溫性高3.環(huán)境的適應性高4.熱流密度可變性5.熱流方向的可逆性6.高穩(wěn)定性

(保證三年壽命)熱管之應用1.電子電力機半導體元件的冷卻2.改善熱交換器的效能3.電力電纜的冷卻4.馬達的冷卻5.高緯度地區(qū)的道路融雪6.太空船的熱控制元件PS2D/T熱管的市場前景熱導管產(chǎn)品市場範圍相當廣泛，未來將是許多電子電器產(chǎn)品散熱必備的基本之件。舉凡電源供應器、投影機、筆記型電腦、工業(yè)電腦,遊戲機及桌上型電腦，皆有其散熱考量之應用。2003新產(chǎn)品開發(fā)計畫熱管新產(chǎn)品FlattenHeatPipeThermalTowerLoopHeatPipeVaporChamberVaporChamber
