Internal face and outside wall surface be screwed surface；The excircle of the drive end bearing bracket is connected to the front end of the shell, institute
It states drive end bearing bracket and is provided with medium inlet and media outlet, the medium inlet is located at lower half, and the media outlet is located at upper half
Portion；The middle of the inside of the drive end bearing bracket is provided with the lagging of right-angled intersection and perpendicular baffle, so as to by the drive end bearing bracket
Inner space is divided into upper left quarter, lower left quarter, upper right quarter and right lower quadrant；The copper pipe is divided into two systems as medium channel,
One system is that medium enters copper pipe from lower left quarter, is gone out copper pipe from upper left quarter, another system is that medium enters from right lower quadrant
Copper pipe is gone out copper pipe from upper right quarter；The rear end cap is welded in the rear end of the shell, and the rear end cap is by cylindrical shell and portion
Bulb separation face is welded, and the cylindrical shell is connected with the rear end of the shell；The spoiler is the discount vibram outlet more than semicircle, is arranged
Mode arranges for part along the enclosure proportional spacing, and the discount vibram outlet of adjacent spoiler is located at horizontal left and right two respectively
Side makes the runner in the shell form the passage of left and right snake-like swing.
Shell of the present invention is relatively thin housing, can not employ the form installation front-end and back-end of bolt or flange
Component, therefore after first welded and installed noseplate and rear bottom plate, it is possible to opened up on noseplate and rear bottom plate bolt hole or
Flange hole is easily installed other component.

Specific embodiment
Technical solution to further illustrate the present invention below with reference to the accompanying drawings and specific embodiments.
Heat pump air conditioner dual system evaporator, including shell 1, copper pipe 2, drive end bearing bracket 3, rear end cap 4 and spoiler 5；It is described outer
The both ends of shell 1 are respectively welded noseplate 15 and rear bottom plate 16, and the noseplate 15 is circular slab, is welded in the shell 1
Front end, offer hole；Bottom plate 16 is Circular Plate after described, is welded in the rear end of the shell 1；The shell 1 be compared with
Thin housing can not employ the component of the form installation front-end and back-end of bolt or flange, therefore bottom before first welded and installed
After plate 15 and rear bottom plate 16, it is possible to open up bolt hole or flange hole on noseplate 15 and rear bottom plate 16, be easily installed it
His component.The copper pipe 2 is entered by the lower half of the drive end bearing bracket 3 in the shell 1, described in being extended in the shell 1
The rear end of shell 1 is turned back again to the first half of the drive end bearing bracket 3；The internal face and outside wall surface of the copper pipe 2 are to be threaded
Surface；The inside and outside wall surface of copper pipe 2 is all that thread surface can enhance heat exchange area, so as to improve heat exchange efficiency, reduces energy consumption；
