It is interior, it is turned back again to the first half of the drive end bearing bracket in the rear end that the shell is extended in the shell；The inner wall of the copper pipe
Face and outside wall surface are screwed surface；The excircle of the drive end bearing bracket is connected to the front end of the shell, the front end
Lid is provided with medium inlet and media outlet, and the medium inlet is located at lower half, and the media outlet is located at the first half；It is described
The middle of the inside of drive end bearing bracket is provided with lagging, and the inner space of the drive end bearing bracket is divided into the first half by the lagging
And lower half；The first half is in the middle part of the collection of the medium inlet of the copper pipe, and the lower half is the medium of the copper pipe
In the middle part of the collection of outlet；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
It connects, the cylindrical shell is connected with the rear end of the shell；The spoiler is multiple, is sequentially equally spacedly arranged in described
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；Water inlet, water outlet, gas vent and osculum use spiral shell
Line connects, easy for installation, and easy Maintenance and Repair；Failure rate is lower for flanged joint.

Specific embodiment
Technical solution to further illustrate the present invention below with reference to the accompanying drawings and specific embodiments.
Handpiece Water Chilling Units single 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
Water inlet pipe is threadedly connected to, the water outlet 12 is threaded with casing by being threadedly connected to outlet pipe, the gas vent 13, should
Casing installs air bleeding valve again；The osculum 14 is threaded with casing, which installs air bleeding valve again；Shell 1 occupies whole
All spaces of a evaporator, therefore pre-set water and the intake-outlet of medium on shell 1 and can save big quantity space, it is excellent
The design of host is changed；Water inlet 11, water outlet 12, gas vent and osculum 14 are easy for installation using threaded connection, and
And easy Maintenance and Repair；Failure rate is lower for flanged joint.The copper pipe 2 by the drive end bearing bracket 3 lower half into
Enter in the shell 1, turned back again to the first half of the drive end bearing bracket 3 in the rear end that the shell 1 is extended in the shell 1；
The internal face and outside wall surface of the copper pipe 2 are screwed surface；The inside and outside wall surface of copper pipe 2 is all that thread surface can increase
