Abstract

The heat transfer limit of heat pipes is investigated by pool boiling experiments in a standard apparatus with a capillary layer placed on a copper tube. The capillary layer is a hollow cylinder made of bronze with a wall thickness of 2 mm and the test fluids are methanol and n-pentane. The setting is comparable to high-flux tubes already investigated in the literature. In dependence on the heat flux, three to four sections with different characteristics are identified. Compared to plain copper tubes, the heat transfer is partially increased by a factor of 12 until the limit is reached at around 70 kW m⁻².

浸没式毛细管结构上甲醇和正戊烷蒸发的实验研究

通过在铜管上放置毛细管层的标准装置中进行池沸实验，研究了热管的传热极限。毛细管层是一个壁厚为 2 毫米的青铜空心圆柱体，测试流体为甲醇和正戊烷。这种设置与文献中已研究过的高通量管相当。根据热通量的不同，可确定三至四个具有不同特性的部分。与普通铜管相比，传热量部分增加了 12 倍，直到 70 kW m-2 左右达到极限。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
