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 shell dry type heat exchanger.
For this purpose, the present invention uses following technical scheme：
Heat pump air conditioner shell dry type heat exchanger, including shell, copper pipe, drive end bearing bracket, rear end cap and spoiler；The both ends of the shell
Noseplate and rear bottom plate are respectively welded, the noseplate is circular slab, is welded in the front end of the shell, offers
Hole；Bottom plate is Circular Plate after described, is welded in the rear end of the shell；The copper pipe is entered by the lower half of the drive end bearing bracket
In the 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
The internal face and outside wall surface of pipe are screwed surface；The excircle of the drive end bearing bracket by being bolted in the shell,
The drive end bearing bracket is provided with medium inlet and media outlet, and the medium inlet is located at lower half, and the media outlet is located at upper
Half portion；The 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 excircle of the rear end cap is installed by bolt and sealed
It blocks up in the rear end of the shell, is provided with gasket between end cap and shell in the rear；The spoiler is the circle more than semicircle
It lacks, arrangement arranges for part along the enclosure proportional spacing, and the discount vibram outlet of adjacent spoiler is located at respectively erects
Straight both sides up and down, make the runner in the shell form the passage for the turbulent flow that teeters.
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.
