The working principle is as follows:

cooling water enters the cooling water cavity through the water inlet pipe 7 to exchange heat with the bearing arranged in the inner water jacket 2, so that the temperature of the bearing is reduced. The exchanged cooling water is discharged through the water outlet pipe 6, and circulating water cooling is realized through an external pipeline.

In some of these embodiments, the outlet pipe 6 is located above the inlet pipe 7. Under the condition of one atmospheric pressure, the temperature of water is in the range of 4-100 ℃, and the density of cold water is higher than that of hot water. Therefore, the hot water is above the cold water, so the water outlet pipe 6 is arranged above, and the cooling water after heat exchange is convenient to discharge.

In some embodiments, the water outlet pipe 6 is in an L-shaped structure, and the open end of the water outlet pipe 6 located in the cooling water cavity is arranged at the upper part of the cooling water cavity.
