Detailed Description

The invention will be further described with reference to the following figures and examples:

as shown together with fig. 1 to 3, a bearing housing cooling device includes an inner housing 1, an outer housing 2, and a partition plate 4 disposed perpendicular to the inner housing 1 and the outer housing 2. The partition plate 4 penetrates the outer case 2 and extends to the outer surface of the inner case 1. A gap is formed between the inner shell 1 and the outer shell 2, the separation plate 4 divides the gap into a left water channel 10 and a right water channel 11, a first separation bulge 31 and a second separation bulge 32 for separating the gap are further arranged between the inner shell 1 and the outer shell 2, the first separation bulge 31 is arranged in the left water channel 10, and the second separation bulge 32 is simultaneously arranged in the left water channel 10 and the right water channel 11; the shell 2 is provided with a water inlet 21 and a water outlet 22, and the water inlet 21 and the water outlet 22 are positioned on two sides of one of the interval bulges; the partition plate 4 is provided with a first connecting water channel 41 and a second connecting water channel 42, and the first connecting water channel 41 and the second connecting water channel 42 are respectively communicated with the left water channel 10 and the right water channel 11; the water inlet 21 and the first communication water channel 41 are positioned between two adjacent spacing bulges.

The housing 2 and the spacing projections are preferably of one-piece construction.

The reinforcing ribs 8 are uniformly distributed on the peripheral surface of the shell 2, and the reinforcing ribs 8 are simultaneously connected with the shell 2 and the partition plate 4, so that the structure of the bearing seat cooling device is more stable.
