The middle of side is provided with the lagging of right-angled intersection and perpendicular baffle, so as to which the inner space of the drive end bearing bracket is divided into upper left
Portion, lower left quarter, upper right quarter and right lower quadrant;The copper pipe is divided into two systems as medium channel, and a system is medium from a left side
Lower part enters copper pipe, goes out copper pipe from upper left quarter, another system is that medium enters copper pipe from right lower quadrant, goes out copper from upper right quarter
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, described
Cylindrical shell is connected with the rear end of the shell;The spoiler is multiple, is sequentially equally spacedly arranged in the enclosure, and
Perpendicular to the cylindrical housings of the shell;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.

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