工作流体
摘要：
本发明提供一种工作流体，其包括：一表面张力随温度升高而增大的液体；及分散于所述液体中的多个纳米粒子，所述液体含有长链醇，所述长链醇选自碳原子个数在4到10之间的醇类中的一种或几种的混合，所述液体中长链醇的浓度大于0.0005摩尔/升，所述纳米粒子选自碳材、金属材料及陶瓷材料中的一种或几种的混合。本发明的工作流体用于热管中时，利用均匀分散的纳米粒子来提高工作流体的热传导率，并利用一表面张力随温度升高而增大的液体来提高热管的毛细极限，两者结合可同时提高热管的热传导效率及热管的稳定性。
摘要（英）：

This invention provides a working fluid. It includes a liquid whose surface tension is increasing with the temperature and a lot of nanoparticles dispersed in above liquid. When this working fluid uses in heat pipe, the heat conductimetry of the working liquid is improved by the homogenously dispersed nanoparticles, and capillary limit of the heat pipe is enhanced by the liquid whose surface tension is increasing with the temperature. While combining the two above, both the heat conduction efficiency and the stability of the heat pipe can be improved simultaneously.
