In an embodiment, referring to fig. 5 and 6, the oil blocking portion 400 further includes a middle beam 440, a length of the middle beam 440 is greater than a length of the oil blocking portion 400, and the first side plate 410 and the second side plate 420 are spaced apart from a side surface of the middle beam 440; the top surface of the middle beam 440 can be fixedly connected with the bottom surface of the middle plate of the top plate 430 through screws, and the middle beam 440 can also be fixedly connected with the top plate 430 through other methods such as welding and clamping; the front end and the rear end of the middle beam 440 are respectively connected and fixed with the inner wall surfaces of the front side and the rear side of the deflector 20, the inner wall surface of the front end of the deflector 20 is an inclined surface, the front end surface and the rear end surface of the middle beam 440 are inclined surfaces, the section of the middle beam 440 perpendicular to the axis direction is in an isosceles trapezoid shape, and the inclined surface of the front end of the middle beam 440 is matched with the inner wall surface of the front end of the deflector 20 and is fixed through screws. The center beam 440 is provided to serve as an oil barrier and to provide support for the condensate plate assembly 40. As shown in fig. 4, 6 and 8, the rear end of the intermediate beam 440 extends above the oil guide groove 201, and the oil on the surface of the intermediate beam 440 can flow into the oil guide groove 201.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
