In the shell, turned back again to the first half of the drive end bearing bracket in the rear end that the shell is extended in the shell；The copper
The internal face and outside wall surface of pipe are screwed surface；The excircle of the drive end bearing bracket is connected to the front end of the shell,
The drive end bearing bracket is provided with medium inlet and media outlet, and the medium inlet is located at lower half, and the media outlet is located at upper
Half portion；The middle of the inside of the drive end bearing bracket is provided with the lagging of right-angled intersection and perpendicular baffle, so as to by the drive end bearing bracket
Inner space be divided into upper left quarter, lower left quarter, upper right quarter and right lower quadrant；The copper pipe is divided into two as medium channel
System, a system is that medium enters copper pipe from lower left quarter, is gone out copper pipe from upper left quarter, another system be medium from right lower quadrant into
Enter copper pipe, go out copper pipe from upper right quarter；The rear end cap is welded in the rear end of the shell, the rear end cap by cylindrical shell and
Spherical calotte is welded, and the cylindrical shell is connected with the rear end of the shell；The spoiler be more than semicircle discount vibram outlet, cloth
It puts mode to arrange along the enclosure proportional spacing for part, the discount vibram outlet of adjacent spoiler is located above and below vertical respectively
Both sides make the runner in the shell form the passage for the turbulent flow that teeters.
Shell of the present invention is relatively thin housing, can not employ the form installation front-end and back-end of bolt or flange
Component, therefore after first welded and installed noseplate and rear bottom plate, it is possible to opened up on noseplate and rear bottom plate bolt hole or
Flange hole is easily installed other component.
