Abstract

PURPOSE: To raise the efficiency of cooling even in vertical state by providing a columnar body by which to form a space for holding a cooling liquid at the opposite end side of the cooling region in the heating region hollow portion of a heat pipe to be used in the rotary shaft of a rotary electric machine, etc.
CONSTITUTION: A columnar body 42 projecting toward the hollow portion of a cooling region 28b is provided through a space at the lower end 28e of the hollow portion 40 of the heating region 28a of a heat pipe. Since by this, a working liquid 18 is kept in a long ring state in contact with the heating region inner wall 28'a of the hollow portion 40 even when its amount is used in the horizontal state, the liquid level is kept at high levels and therefore, its contact area is increased, combined with the rotary centrifugal force of a rotator 28. Thus, even when the heat pipe is used in a vertical state, good working can be attained.
