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 evaporator.
For this purpose, the present invention uses following technical scheme：
Heat pump air conditioner evaporator, including shell, copper pipe, drive end bearing bracket, rear end cap and spoiler；The both ends of the shell are respectively welded
There are noseplate and rear bottom plate, the noseplate is circular slab, is welded in the front end of the shell, offers hole；After described
Bottom plate is Circular Plate, is welded in the rear end of the shell；The copper pipe enters the shell by the lower half of the drive end bearing bracket
It is interior, 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 inner wall of the copper pipe
Face and outside wall surface are screwed surface；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.
