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 dual system shell dry type heat exchanger, including shell 1, copper pipe 2, drive end bearing bracket 3, rear end cap 4 and is disturbed
Flowing plate 5；The shell 1 is cylindrical shell, is provided with water inlet 11, water outlet 12, gas vent 13 and osculum 14；It is described into
The mouth of a river 11 is threadedly coupled by being threadedly connected to water inlet pipe, the water outlet 12 by being threadedly connected to outlet pipe, the gas vent 13
There is casing, which installs air bleeding valve again；The osculum 14 is threaded with casing, which installs air bleeding valve again；Shell 1
All spaces of entire evaporator are occupied, therefore pre-set water and the intake-outlet of medium on shell 1 to save greatly
Quantity space optimizes the design of host；Water inlet 11, water outlet 12, gas vent and osculum 14 using being threadedly coupled, are pacified
Dress is convenient, and easy Maintenance and Repair；Failure rate is lower for flanged joint.The copper pipe 2 is by the drive end bearing bracket 3
Lower half enters in the shell 1, is turned back again to the drive end bearing bracket 3 in the rear end that the shell 1 is extended in the shell 1
The first half；The internal face of the copper pipe 2 is smooth, and outside wall surface is screw thread；The inner wall smooth of the copper pipe 2 then fluid media (medium)
Flow resistance it is smaller, can improve efficiency reduce energy consumption；The outer wall had both been easily installed copper pipe 2, Er Qiejia for thread surface
Work manufacture copper pipe also reduces cost；The excircle of the drive end bearing bracket 3 is connected to the front end of the shell 1, and the drive end bearing bracket 3 is set
