The rear end that the shell is extended in the shell is turned back again to the first half of the drive end bearing bracket；The internal face of the copper pipe and outer
Wall surface is screwed surface；The excircle of the drive end bearing bracket is connected to the front end of the shell, and the drive end bearing bracket is set
There are medium inlet and media outlet, the medium inlet is located at lower half, and the media outlet is located at the first half；The drive end bearing bracket
The middle of inside be provided with lagging, the inner space of the drive end bearing bracket is divided into the first half and lower half by the lagging
Portion；The first half is in the middle part of the collection of the medium inlet of the copper pipe, and the lower half is the media outlet of the copper pipe
Collection middle part；The excircle of the rear end cap is plugged in the rear end of the shell by bolt installation, in the rear end cap and shell it
Between be provided with gasket；The spoiler is multiple, is sequentially equally spacedly arranged in the enclosure, and perpendicular to the shell
Cylindrical housings；Each spoiler is provided with several fixed links.
Shell of the present invention occupies all spaces of entire evaporator, thus pre-set on the shell water and medium into
Water outlet can save big quantity space, optimize the design of host；Inlet and outlet are easy for installation using flanged joint, hold
Easy care overhauls；The frequency of use of gas vent and osculum is not high, and failure rate is very low, is let out so can be reduced using welding method
Dew.
