技術名稱: 熱管及其加工方法

技術簡介

毛細極限是銅水熱管最容易遇到的傳熱限制。若加熱區工作流體蒸發速率超過毛細力將工作流體帶回之速率,蒸發區會產生乾化現象導致熱管失效,達到最大工作熱傳量之極限。本專利利用化學反應有效提升熱管內毛細結構之毛細力,藉以提升熱管最大熱傳量性能。運用於LED或電子產品等之散熱模組中,可有效解決散熱問題並降低整體成本。

Abstract

The capillary limit of traditional copper-water heat pipe for thermal management of electronics will occur once the evaporation rate of working in evaporator is higher than the refill rate by wick structure. In this patent, the maximum heat flux of the heat pipe was effective improved by increasing the capillary force of the wicks in heat pipe with chemical oxidation method. The applications of these high performance heat pipes are heat dissipation module, heat exchanger, and so on. This technology provides a better solution for thermal management of LED lamps or electronics and reduces the cost of heat dissipation module.
