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 be more than semicircle discount vibram outlet, arrangement for part along the enclosure it is uniform between
It is arranged away from ground, the discount vibram outlet of adjacent spoiler is located at vertical both sides up and down respectively, forms the runner in the shell and shakes up and down
Put the passage of turbulent flow.
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.
