Specific implementation mode
Technical solution to further illustrate the present invention below with reference to the accompanying drawings and specific embodiments.
Central air-conditioning 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 disturb
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 by flanged joint in water inlet pipe, and for the water outlet 12 by flanged joint in outlet pipe, the gas vent 13 is welded with set
Pipe, the casing install air bleeding valve again；The osculum 14 is welded 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 and water outlet 12 are easy for installation using flanged joint, are easy Maintenance and Repair；Gas vent and row
The frequency of use in water hole 14 is not high, and failure rate is very low, so can reduce leakage using welding method.The copper pipe 2 is by described
The lower half of drive end bearing bracket 3 enters in the shell 1, is turned back again to described in the rear end for extending to the shell 1 in the shell 1
The first half of drive end bearing bracket 3；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 the flow resistance of fluid media (medium) is smaller, and can improve efficiency reduces energy consumption；The outer wall is that thread surface is both easily installed copper
