Description

Heat pump air conditioner dual system shell dry type heat exchanger

Technical field

The present invention relates to technical field of central air more particularly to heat pump air conditioner dual system shell dry type heat exchangers.

Background technique

Central air-conditioning provides cold water using the form of centralized cooling supply for whole building, is then changed again by fan coil etc. Cooling capacity is sent to each room by hot component step by step.Although building structure has generally reserved certain space to central air conditioning Group, but the form of the evaporator of the water cooler of central air-conditioning is varied, including the knot such as shell-and-tube heat exchanger, plate heat exchanger Structure requires to occupy very large space.When especially refrigeration requirement is especially huge, multiple water coolers is needed to work at the same time When being just able to satisfy cooling capacity requirement, need to arrange enough evaporators in the same space as far as possible.

Dry evaporator refers 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 water cooler, is not suitable for cooling tower, therefore in condenser end segment Space is saved.But evaporator end also needs to save space, and more meticulous structure is needed to design.

Summary of the invention

It is an object of the invention to propose a kind of heat pump air conditioner dual system shell dry type heat exchanger.

For this purpose, the present invention uses following technical scheme：

Heat pump air conditioner dual system shell dry type heat exchanger, including shell, copper pipe, drive end bearing bracket, rear end cap and spoiler；The shell Both ends be respectively welded noseplate and rear bottom plate, the noseplate is circular slab, is welded in the front end of the shell, opens Equipped with hole；Bottom plate is Circular Plate after described, is welded in the rear end of the shell；The copper pipe by the drive end bearing bracket lower half Into in the shell, turned back again in the rear end for extending to the shell in the shell to the upper half of the drive end bearing bracket；Institute The inner wall and outside wall surface for stating copper pipe are screwed surface；Before the excircle of the drive end bearing bracket is connected to the shell End, the drive end bearing bracket are provided with medium inlet and media outlet, and the medium inlet is located at lower half, and the media outlet is located at The upper half；The middle of the inside of the drive end bearing bracket is provided with the lagging and perpendicular baffle of right-angled intersection, thus by the front end The inner space of lid is divided into upper left quarter, lower left quarter, upper right quarter and right lower quadrant；The copper pipe is divided into two as medium channel System, a system are that medium from lower left quarter enters copper pipe, are gone out copper pipe from upper left quarter, another system be medium from right lower quadrant into Enter copper pipe, goes out copper pipe from upper right quarter；The excircle of the rear end cap is plugged in the rear end of the shell by bolt installation, in institute It states and is provided with gasket between rear end cap and shell；The spoiler is the discount vibram outlet more than semicircle, and arrangement is part along institute It arranges with stating interior of shell proportional spacing, the discount vibram outlet of adjacent spoiler is located at vertical two sides up and down, makes in the shell Runner formed teeter turbulent flow channel.

Shell of the present invention is relatively thin shell, and the form that can not use bolt or flange installs front-end and back-end Component, therefore first welding installation noseplate and rear bottom plate after, so that it may opened up on noseplate and rear bottom plate bolt hole or Flange hole is easily installed other component.

Specific embodiment

To further illustrate the technical scheme of the present invention below with reference to the accompanying drawings and specific embodiments.

Heat pump air conditioner dual system shell dry type heat exchanger, including shell 1, copper pipe 2, drive end bearing bracket 3, rear end cap 4 and spoiler 5；The both ends of the shell 1 are respectively welded noseplate 15 and rear bottom plate 16, and the noseplate 15 is circular slab, are welded in institute The front end for stating shell 1, offers hole；Bottom plate 16 is Circular Plate after described, is welded in the rear end of the shell 1；It is described outer Shell 1 is relatively thin shell, can not use the component of the form installation front-end and back-end of bolt or flange, therefore first welding peace After filling noseplate 15 and rear bottom plate 16, so that it may open up bolt hole or flange hole on noseplate 15 and rear bottom plate 16, be convenient for Other component is installed.The copper pipe 2 is entered in the shell 1 by the lower half of the drive end bearing bracket 3, is stretched in the shell 1 It is turned back again to the rear end of the shell 1 to the upper half of the drive end bearing bracket 3；The inner wall and outside wall surface of the copper pipe 2 are band Threaded surface；The inside and outside wall surface of copper pipe 2 is all that thread surface can enhance heat exchange area, to improve heat exchange efficiency, is dropped Low energy consumption；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 provided with 31 He of medium inlet Media outlet 32, the medium inlet 31 are located at lower half, and the media outlet 32 is located at the upper half；The drive end bearing bracket 3 it is interior The middle of side is provided with the lagging and perpendicular baffle of right-angled intersection, so that the inner space of the drive end bearing bracket 3 is divided into a left side Top, lower left quarter, upper right quarter and right lower quadrant；The copper pipe 2 is divided into two systems as medium channel, a system be medium from Lower left quarter enters copper pipe 2, goes out copper pipe 2 from upper left quarter, another system is that medium from right lower quadrant enters copper pipe 2, from upper right quarter It goes out copper pipe 2；When needing to increase the refrigeration work consumption of host, the power of simple system has certain limiting value, cannot infinitely increase Add, therefore left and right two systems are set in same evaporator shell 1, to make to have more in the volume of the same evaporator Big refrigerating capacity.

The excircle of the rear end cap 4 is plugged in the rear end of the shell 1 by bolt installation, in the rear end cap 4 and outside Gasket is provided between shell 1；

Manufacture and after-sale service and maintenance can be facilitated by being bolted；

The spoiler 5 is the discount vibram outlet more than semicircle, and arrangement is that part is arranged along the 1 inside proportional spacing of shell Column, the discount vibram outlet of adjacent spoiler 5 are located at vertical two sides up and down, so that the runner formation in the shell 1 is teetered disorderly The channel of stream.

Snakelike flow-disturbing improves heat exchange efficiency, can increase the turbulence factor of water flow under upper and lower installation condition, and raising is changed The thermal efficiency；

The thickness of the noseplate 15 and rear bottom plate 16 is not less than 5mm.

The thickness of copper pipe is not less than 0.6mm；The screw thread of the copper pipe of every 1cm is no less than 22 circles.
