Specific embodiment
Technical solution to further illustrate the present invention below with reference to the accompanying drawings and specific embodiments.
Handpiece Water Chilling Units dual system shell 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；
