があった。There are two types of cooling methods: water cooling and air cooling. The structure of the conventional water cooling system is shown in Figure 1 (Utility Model Publication No. 55-166144). Directional dimension O. An oil guide 6 is provided between the bottom wall of the oil tank 1 and the lower end surface e of the shaft collar 2, and the lower end surface e of the shaft collar is The flow of cooling oil through the oil cooling pipe 4 and the flow of lubricating oil heat-exchanged by the outer wall of the oil cooling pipe 4 and the oil guide 6
Separate by. The water cooling system has a simple structure and high cooling capacity, but in addition to the oil tank, it requires incidental equipment such as a water supply tube, a radiator, a cooling fan, and water supply and drainage piping. In addition, there was a drawback that maintenance and inspection were required to prevent corrosion and scale adhesion of the piping.

である。The structure of the air cooling system is shown in Figure 2. A heat pipe 16 is attached to the oil cover 5 provided on the top of the oil cover 7.
The heat generated by the guide bearing 3 is transferred to the upper fin 8 through a heat pipe 16, and cooled by forced air cooling. The air cooling system using the heat nozzle 16 has a simple structure, does not require any incidental equipment unlike the water cooling system, and does not require maintenance or inspection.

流速を高めるだめのガイドを設ければ良い。However, air-cooled systems have lower cooling capacity than water-cooled systems, and there are limits to their applicability when used in guide bearings for water turbine generators. Factors that determine the cooling capacity of the heat pipe 16 include the temperature difference between the lubricating oil and the outside air, the fin area, and the fin efficiency. Among these factors, temperature difference and fin area are
Although it is automatically determined by the installation conditions and structural design of the water turbine generator, the fin efficiency varies depending on the fins 8 and the flow rate of the cooling medium. For example, as shown in FIG. 3, the relationship between the flow velocity of the cooling medium and the heat transfer coefficient of the fins is as shown in FIG. However, in the conventional structure, the heat dissipation part uses forced air cooling, and the flow rate can be freely selected, but inside the oil tank, the shaft collar is used.
Only the flow velocity generated by stirring by rotation of 2 can be obtained,
The cooling capacity is determined by the fin efficiency of the fins 9 in the oil tank 1, and the conventional structure has a drawback that the fin efficiency of the fins 9 is low. Therefore, in order to improve the cooling capacity of the heat pipe, it is sufficient to provide a guide to increase the flow velocity when passing through the fins, as shown in FIG.
本発明の要点は、油タンク内のヒートパイプの受熱フィ
ンを通過する流速を高め冷却能力を向上させるにある。The gist of the present invention is to increase the flow rate passing through the heat receiving fins of the heat pipe in the oil tank and to improve the cooling capacity.

ことができ冷却効率が高まる。An embodiment of the present invention will be described below with reference to FIG. Heat receiving fins 9 of the heat pipe 16 installed in the oil tank 1
Around the shaft collar 2, a partition plate 11 is attached to the bearing frame 12 so that the oil guide 1O installed along the direction of the oil flow generated by the rotation of the shaft collar 2 and the heat receiving fin 9 maximize the flow velocity. will be installed. Further, FIG. 6 shows a cross section of the heat receiving fin portion of FIG. 5. This figure shows the oil flow in the oil tank 1. The oil flow generated by the rotation of the shaft collar 2 is guided to the heat receiving fins 9 by the oil guide 10 and the partition plate 1). Moreover, the oil flow is restricted by the oil guide 10 and the partition plate 11, and the flow velocity reaches its maximum at the heat receiving fin 9 portion. Therefore, as described above, the fin efficiency of the heat receiving fins 9 is increased, and as a result, the cooling capacity of the heat pipe 16 is improved. Further, in the air cooling system using the heat pipe 16, the cooling capacity is improved by heat radiation from the heat pipe 16 and the outer wall of the oil/oil 2, but according to the present invention, the oil guide 10 improves the cooling capacity. Heat radiation from the heat pipe 16 and the outer wall of the oil tank 1 can be shared, increasing cooling efficiency.
