Casing is threaded with, which installs air bleeding valve again；The copper pipe is entered by the lower half of the drive end bearing bracket in the shell,
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 internal face of the copper pipe is
Smooth, outside wall surface is screw thread；By being bolted in the shell, the drive end bearing bracket is provided with the excircle of the drive end bearing bracket
Medium inlet and media outlet, the medium inlet are located at lower half, and the media outlet is located at the first half；The medium inlet
Casing is welded with media outlet, which is provided with sinking step, the sinking step welding medium tube channel；Institute
It states and venting plug is provided at the top of media outlet；After the excircle of the rear end cap is plugged in the shell by bolt installation
End, is provided with gasket in the rear between end cap and shell；The spoiler is the discount vibram outlet more than semicircle, and arrangement is part
It is arranged along the enclosure proportional spacing, the discount vibram outlet of adjacent spoiler is located at the horizontal left and right sides respectively, makes described
Runner in shell 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；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 flow-disturbing shell evaporator, including shell 1, copper pipe 2, drive end bearing bracket 3, rear end cap 4 and spoiler 5；It is described
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 spiral shell
Line is connected to water inlet pipe, and the water outlet 12 is threaded with casing by being threadedly connected to outlet pipe, the gas vent 13, the set
Pipe installs air bleeding valve again；The osculum 14 is threaded with casing, which installs air bleeding valve again；Shell 1 occupies entirely
All spaces of evaporator, therefore pre-set water and the intake-outlet of medium on shell 1 and can save big quantity space, optimize
The design of host；Water inlet 11, water outlet 12, gas vent and osculum 14 are easy for installation using threaded connection, and
Easy Maintenance and Repair；Failure rate is lower for flanged joint.The copper pipe 2 is entered by the lower half of the drive end bearing bracket 3
