PROBLEM TO BE SOLVED: To solve a problem of easily causing a passing obstacle.SOLUTION: Two sets of cooling parts 2 and 2a are provided in a box 1, and the respective cooling parts 2 and 2a are constituted of one cooling pipe 3 vertically penetrating through the box 1. The cooling parts 2 and 2a are arranged in areas 1a and 1b formed by dividing the inside of the box 1 into two sections, and a partition plate 10 provided in a boundary part between the areas 1a and 1b is formed so as to be communicable between the downstream side of the upstream side area 1a and the upstream side of the downstream side area 1b. A meandering flow passage 4 is formed in the box 1, and an inflow port 5 is formed in an upstream end part of the flow passage 4, and an outflow port 6 is formed in a downstream end part, in a side surface of the box 1. Air including oil mist passing through the flow passage 4 is cooled by outside air passing through the inside of a cooling pipe 3, and the inclusion mist is removed by condensing-sticking in a dew to an outer surface of the cooling pipe 3. The passing air is further cooled, and the inclusion mist is condensed, and is removed by colliding with/sticking to a flow passage forming surface, but the flow passage 4 is not blocked up due to having a sufficient extent. |
