Structure is required for occupying very big space., it is necessary to which multiple handpiece Water Chilling Units work at the same time when especially refrigeration requirement is especially huge
, it is necessary to arrange enough evaporators in same space as far as possible when could meet cold requirement.
Dry evaporator referred in the coolant channel of evaporator, and refrigerant is in exit evaporating completely, no
There are liquid refrigerant, such evaporator is exclusively used in air-cooled handpiece Water Chilling Units, is not suitable for cooling tower, therefore in condenser end segment
Space is saved.But evaporator end also needs to save space the structure design, it is necessary to more meticulous.
The content of the invention
It is an object of the invention to propose a kind of heat pump air conditioner flow-disturbing evaporator.
For this purpose, the present invention uses following technical scheme:
Heat pump air conditioner flow-disturbing evaporator, including shell, copper pipe, drive end bearing bracket, rear end cap and spoiler;The both ends difference of the shell
Noseplate and rear bottom plate are welded with, the noseplate is circular slab, is welded in the front end of the shell, offers hole;Institute
Rear bottom plate is stated as Circular Plate, is welded in the rear end of the shell;The copper pipe is as described in entering the lower half of the drive end bearing bracket
In shell, 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 copper pipe
Internal face is smooth, and outside wall surface is screw thread;The excircle of the drive end bearing bracket is by being bolted in 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
Medium inlet and media outlet are welded with casing, which is provided with sinking step, the sinking step welding medium
Tube channel;Venting plug is provided at the top of the media outlet;The rear end cap is welded in the rear end of the shell, the rear end
Lid is welded by cylindrical shell and spherical calotte, and the cylindrical shell is connected with the rear end of the shell;The spoiler is super
The discount vibram outlet of semicircle is crossed, arrangement arranges for part along the enclosure proportional spacing, the discount vibram outlet of adjacent spoiler
It is located at the horizontal left and right sides respectively, the runner in the shell is made to form the passage of left and right snake-like swing.
Shell of the present invention is relatively thin housing, can not employ the form installation front-end and back-end of bolt or flange
Component, therefore after first welded and installed noseplate and rear bottom plate, it is possible to opened up on noseplate and rear bottom plate bolt hole or
Flange hole is easily installed other component.

Specific embodiment
Technical solution to further illustrate the present invention below with reference to the accompanying drawings and specific embodiments.
Heat pump air conditioner flow-disturbing evaporator, including shell 1, copper pipe 2, drive end bearing bracket 3, rear end cap 4 and spoiler 5;The shell 1
Both ends be respectively welded noseplate 15 and rear bottom plate 16, the noseplate 15 is circular slab, before being welded in the shell 1
End, offers hole;Bottom plate 16 is Circular Plate after described, is welded in the rear end of the shell 1;The shell 1 is relatively thin
Housing can not employ the component of the form installation front-end and back-end of bolt or flange, therefore first welded and installed noseplate 15
After rear bottom plate 16, it is possible to open up bolt hole or flange hole on noseplate 15 and rear bottom plate 16, be easily installed other portions
Part.The copper pipe 2 by the lower half of the drive end bearing bracket 3 into the shell 1, in extending to the shell 1 in the shell 1
Rear end turned back again to the first half of the drive end bearing bracket 3;The internal face of the copper pipe 2 is smooth, and outside wall surface is screw thread;Institute
State that the flow resistance of the inner wall smooth of copper pipe 2 then fluid media (medium) is smaller, and can improve efficiency reduces energy consumption;The outer wall is screw thread
Surface had both been easily installed copper pipe 2, and fabricated copper pipe and also reduce cost;The excircle of the drive end bearing bracket 3 is connected by bolt
