Middle is provided with lagging, and the inner space of the drive end bearing bracket is divided into the first half and lower half by the lagging；On this
Half portion is in the middle part of the collection of the medium inlet of the copper pipe, and the lower half is in the middle part of the collection of the media outlet of the copper pipe；
The rear end cap is welded in the rear end of the shell, and the rear end cap is welded by cylindrical shell and spherical calotte, the circle
Column shell is connected with the rear end of the shell；The spoiler is the discount vibram outlet more than semicircle, and arrangement is partly along described outer
It arranges to shell inner homogeneous spacing, the discount vibram outlet of adjacent spoiler is located at the horizontal left and right sides respectively, makes the stream in the shell
Road forms 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；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.

Specific embodiment
Technical solution to further illustrate the present invention below with reference to the accompanying drawings and specific embodiments.
Central air-conditioning single system evaporator, including shell 1, copper pipe 2, drive end bearing bracket 3, rear end cap 4 and spoiler 5；It is described outer
Shell 1 is cylindrical shell, is provided with water inlet 11, water outlet 12, gas vent 13 and osculum 14；The water inlet 11 is by flange
Water inlet pipe is connected to, the water outlet 12 is by flanged joint in outlet pipe, and the gas vent 13 is welded with casing, which pacifies again
Fill air bleeding valve；The osculum 14 is welded with casing, which installs air bleeding valve again；Shell 1 occupies the institute of entire evaporator
There is space, therefore pre-set water and the intake-outlet of medium on shell 1 to save big quantity space, optimize setting for host
Meter；Water inlet 11 and water outlet 12 are easy for installation using flanged joint, easy Maintenance and Repair；The use of gas vent and osculum 14
Frequency is not high, and failure rate is very low, so can reduce leakage using welding method.The copper pipe 2 by the drive end bearing bracket 3 lower half
Portion enters in the shell 1, is turned back again to the upper half of the drive end bearing bracket 3 in the rear end that the shell 1 is extended in the shell 1
