らの漏水を封止する封水装置である。FIG. 2 is a vertical cross-sectional view of a bearing portion of a horizontal shaft rotating electric machine and a horizontal shaft water turbine provided with a journal bearing cooled by using a conventional heat pipe as the above-mentioned example. In the figure, reference numeral 1 denotes a rotary shaft, and the rotary shaft 1 is provided with a hollow portion, and the heat pipe 2 is configured by directly enclosing the working liquid in the hollow portion, but the heat receiving portion 2a at one end of the heat pipe 2 is formed. The side shaft is rotatably supported by the journal bearing 3 of the rotating electric machine, and the heat radiating portion 2b side shaft at the other end is attached to the water turbine runner 4. Reference numeral 5 is a bearing stand of the rotating electric machine, 6 is a water turbine casing, and 7 is a water sealing device for sealing water leakage from the water turbine casing 6.

流れる水に放出され軸受の冷却が行なわれる。When the heat generated in the journal shaft 3 is transferred to the heat receiving portion 2a, the heat receiving portion 2a is heated and the working liquid of the heat pipe is evaporated to become vapor, and the pressure of this portion is increased and moves to the heat radiating portion 2b. When the steam reaches the heat radiating portion 2b, the heat is transmitted to the water turbine casing 6 through the water turbine runner 4 and is released to the flowing water, so that the steam is condensed. Condensed hydraulic fluid is rotating shaft 1
The centrifugal force acts to return to the heat receiving portion 2a again. By repeating the above, the heat generated in the journal bearing 3 is radiated to the water flowing in the turbine casing to cool the bearing.

て熱抵抗の問題もあつて熱を十分に水流に放出すること
ができないという欠点があつた。In the structure of the heat radiating portion of the heat pipe as shown in Fig. 2, the effective heat transfer surface of the heat radiating portion is limited by the length of the portion where the turbine runner is fitted to the rotating shaft, and is related to the wall thickness of the turbine However, there is a problem that heat cannot be sufficiently released into the water stream due to the problem of heat resistance.
この発明は上述した事情を考慮して軸受で発生した熱を
水車ランナを経て水車ケーシングを流れる水に放出する
際の放熱効果を向上させる目的でヒートパイプの放熱部
構造を工夫改良することを目的とする。In view of the above-mentioned circumstances, the present invention aims to improve the heat radiation structure of the heat pipe for the purpose of improving the heat radiation effect when the heat generated in the bearing is released to the water flowing through the water turbine casing through the water turbine runner. And

にヒートパイプの放熱部を形成した。In order to achieve the above-mentioned object, in the present invention, a heat radiating portion is provided on the rotating shaft in addition to the conventional heat radiating portion. That is, as its structure, a ring was provided so as to surround the rotating shaft between the water turbine casing and the water sealing device. Then, water was supplied to the gap between the ring and the rotary shaft, and the heat radiating portion of the heat pipe was formed on the rotary shaft inside the ring.

The ring 8 provided by the present invention is mounted between the turbine casing 6 and the water sealing device 7 so as to surround the rotary shaft. Water supplied directly from the iron pipe or from the back surface of the water wheel runner 4 flows through the gap between the ring 8 and the rotating shaft 1 to form the second heat radiating portion 2c in the hollow portion corresponding to the position of this portion. If a cooling fin is provided on the outer diameter portion of the rotary shaft 1 at this portion, the heat transfer coefficient can be increased.

The working liquid in the heat pipe evaporates to become vapor, the pressure of this portion is increased, and the vapor moves to the heat radiating portion 2b and the second heat radiating portion 2c. When this steam reaches the heat radiating portion 2b and the second heat radiating portion 2c, a part of the heat is released to the water flowing through the water turbine casing 6 through the water turbine runner 4, but most of the heat is generated by the ring 8 and the rotating shaft 1. It is released into the water flowing through the gap and condensed. The condensed working fluid returns to the heat receiving portion 2a again by the action of the centrifugal force of the rotating shaft 1. By repeating the above, the heat generated in the journal bearing 3 is released to water to cool the bearing.
