In the shell, turned back again in the rear end for extending to the shell in the shell to the upper half of the drive end bearing bracket；The copper
The inner wall and outside wall surface of pipe are screwed surface；The excircle of the drive end bearing bracket is connected to the front end of the shell,
The drive end bearing bracket is provided with medium inlet and media outlet, and 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 and perpendicular baffle of right-angled intersection, thus by the drive end bearing bracket
Inner space be divided into upper left quarter, lower left quarter, upper right quarter and right lower quadrant；The copper pipe is divided into two as medium channel
System, a system are that medium from lower left quarter enters copper pipe, are gone out copper pipe from upper left quarter, another system be medium from right lower quadrant into
Enter copper pipe, goes out copper pipe from upper right quarter；The rear end cap is welded in the rear end of the shell, the rear end cap by cylindrical shell and
Spherical calotte is welded, and the cylindrical shell is connect with the rear end of the shell；The spoiler be it is multiple, sequentially equally spacedly
It is arranged in the interior of shell, and perpendicular to the cylindrical housings of the shell；It is solid that each spoiler is provided with several
Fixed pole.
Shell of the present invention is relatively thin shell, and the form that can not use bolt or flange installs front-end and back-end
Component, therefore first welding installation noseplate and rear bottom plate after, so that it may opened up on noseplate and rear bottom plate bolt hole or
Flange hole is easily installed other component.

Specific embodiment
To further illustrate the technical scheme of the present invention below with reference to the accompanying drawings and specific embodiments.
Heat pump air conditioner dual-system dry evaporator, including shell 1, copper pipe 2, drive end bearing bracket 3, rear end cap 4 and spoiler 5；Institute
The both ends for stating shell 1 are respectively welded noseplate 15 and rear bottom plate 16, and the noseplate 15 is circular slab, are welded in described outer
The front end of shell 1, offers hole；Bottom plate 16 is Circular Plate after described, is welded in the rear end of the shell 1；The shell 1 is
Relatively thin shell can not use the component of the form installation front-end and back-end of bolt or flange, therefore before first welding installation
After bottom plate 15 and rear bottom plate 16, so that it may open up bolt hole or flange hole on noseplate 15 and rear bottom plate 16, be easily installed
Other component.The copper pipe 2 is entered in the shell 1 by the lower half of the drive end bearing bracket 3, in extending to institute in the shell 1
The rear end for stating shell 1 is turned back again to the upper half of the drive end bearing bracket 3；The inner wall and outside wall surface of the copper pipe 2 are with spiral shell
The surface of line；The inside and outside wall surface of copper pipe 2 is all that thread surface can enhance heat exchange area, to improve heat exchange efficiency, reduces energy
