    • A capillary structure (25) for a heat transfer device, such as a heat pipe (2) is provided having a plurality of particles (27) joined together by a brazing compound (30) such that fillets (33) of the brazing compound are formed between adjacent ones of the plurality of particles (27) and one or more vapor vents (60) are defined in the capillary structere (25). In this way, a network of capillary passageways are formed between the particles (27) and vapor-vents (60) through the capillary structure (25) so as to aid in the transfer of working fluid by capillary action, while the plurality of fillets (33) provide enhanced thermal transfer properties between the plurality of particles (27) so as to greatly improve over all heat transfer efficiency of the device (2). A method of making the capillary structure according to the invention is also presented.
    • 提供了一种用于传热装置(例如热管(2))的毛细管结构(25),其具有通过钎焊化合物(30)连接在一起的多个颗粒(27),使得钎焊化合物的焊脚(33) 形成在所述多个颗粒(27)中的相邻颗粒(27)和一个或多个蒸气排出口(60)之间形成在所述毛细管结构体(25)中。 以这种方式,通过毛细管结构(25)在颗粒(27)和蒸气通道(60)之间形成毛细通道网络,以便通过毛细作用帮助工作流体的传送,而多个圆角 (33)在多个颗粒(27)之间提供增强的热传递特性,以便大大提高装置(2)的所有传热效率。 还提出了制造根据本发明的毛细管结构的方法。
