导热管、转子及旋转电机
摘要：
本发明提供一种能够在较强的离心力发挥作用的环境中有效地实施冷却的导热管、转子及旋转电机。转子(4)具备：转子铁芯(41)；磁体(43)，其沿转子铁芯(41)的中心轴的轴向配置；以及导热管(6)，其绕转子铁芯(41)的中心轴配置，导热管(6)具有：工作液，其设置于导热管(6)的内部空间，通过蒸发和冷凝而使热移动；被加热部(62)，其以相对于中心轴平行的方式延伸，从磁体(43)受热而被加热；以及被冷却部(61)，其配置于被加热部(62)的长边方向上的一侧而被冷却，被冷却部(61)以在从被加热部(62)的长边方向上的一侧朝向被加热部(62)的长边方向上的另一侧的方向上远离转子铁芯(41)的中心轴的方式倾斜。
摘要（英）：

A heat pipe which can effectively achieve cooling in an environment in which high centrifugal force plays a role, a rotor, and a rotary electric machine are provided. The rotor (4) includes: a rotor core (41); a magnet (43) that is arranged along an axial direction of a central axis of the rotor core (41); and a heat pipe (6) that is arranged around the central axis of the rotor core (41), wherein the heat pipe (6) includes: an operation liquid that is provided in an internal space of the heat pipe (6) and that allows heat to move via evaporation and condensation; a heated part (62) that extends so as to be parallel with the central axis, that receives heat from the magnet, and that is heated; and a cooled part (61) that is arranged on one side in a longitudinal direction of the heated part and that is cooled, wherein the cooled part (61) is slanted away from the central axis of the rotor core (41) in a direction from the one side in the longitudinal direction of the heated part (62) toward another side in the longitudinal direction of the heated part (62).
