Into 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；Institute
It is screwed surface to state the internal face of copper pipe and outside wall surface；The excircle of the drive end bearing bracket is by being bolted in described outer
Shell, the drive end bearing bracket are provided with medium inlet and media outlet, and the medium inlet is located at lower half, and the media outlet is located at
The first half；The medium inlet and media outlet are welded with casing, which is provided with sinking step, the lower heavy platform
Rank welding medium tube channel；Venting plug is provided at the top of the media outlet；After the rear end cap is welded in the shell
End, the rear end cap are welded by cylindrical shell and spherical calotte, and the cylindrical shell is connected with the rear end of the shell；It is described
Spoiler is the discount vibram outlet more than semicircle, and arrangement arranges for part along the enclosure proportional spacing, and adjacent disturbs
The discount vibram outlet of flowing plate is located at the horizontal left and right sides respectively, and the runner in the shell is made to form the passage of left and right snake-like swing.
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；The inlet and outlet are arranged at evaporator shell
Side is easier maintenance, and disengaging host is facilitated to carry out trouble shooting and installation.
