Description

Heat pump air conditioner flow-disturbing dual system shell evaporator

Technical field

The present invention relates to technical field of central air more particularly to heat pump air conditioner flow-disturbing dual system shell evaporators.

Background technology

Central air-conditioning provides cold water using the form of centralized cooling for whole building, is then changed again by fan coil etc. Cold 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 handpiece Water Chilling Units of central air-conditioning is varied, including knots such as shell-and-tube heat exchanger, plate heat exchangers 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 dual system shell evaporator.

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

Heat pump air conditioner flow-disturbing dual system shell evaporator, 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 to the first half of the drive end bearing bracket in the rear end that the shell is extended in the shell；Institute The internal face of copper pipe is stated to be smooth, outside wall surface is screw thread；The excircle of the drive end bearing bracket is connected to the front end of 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 middle of the inside of the drive end bearing bracket is provided with the lagging of right-angled intersection and perpendicular baffle, so as to by the drive end bearing bracket Inner space be 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 is that medium enters copper pipe from lower left quarter, is gone out copper pipe from upper left quarter, another system be medium from right lower quadrant into Enter copper pipe, go 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 gasket is provided between rear end cap and shell；The spoiler is the discount vibram outlet more than semicircle, and arrangement is partly along institute It arranges with stating enclosure proportional spacing, the discount vibram outlet of adjacent spoiler is located at the horizontal left and right sides respectively, makes in the shell Runner formed left and right snake-like swing passage.

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 dual system shell evaporator, 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, is welded in institute The front end of shell 1 is stated, 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 housing, can not employ 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, it is possible to 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 by the lower half of the drive end bearing bracket 3 in the shell 1, in stretching, extension in the shell 1 It is turned back again to the first half of the drive end bearing bracket 3 to the rear end of the shell 1；The internal face of the copper pipe 2 is smooth, outside wall surface For screw thread；The flow resistance of the inner wall smooth of the copper pipe 2 then fluid media (medium) is smaller, and can improve efficiency reduces energy consumption；Institute It states outer wall and had both been easily installed copper pipe 2 for thread surface, and fabricate copper pipe and also reduce cost；Outside the drive end bearing bracket 3 Circumference is connected to the front end of the shell 1, and the drive end bearing bracket 3 is provided with medium inlet 31 and media outlet 32, and the medium enters Mouth 31 is located at lower half, and the media outlet 32 is located at the first half；The middle of the inside of the drive end bearing bracket 3 is provided with cross friendship The lagging of fork and perpendicular baffle, so as to which the inner space of the drive end bearing bracket 3 is divided into upper left quarter, lower left quarter, upper right quarter and the right side Lower part；The copper pipe 2 is divided into two systems as medium channel, and a system is that medium enters copper pipe 2 from lower left quarter, from upper left Portion goes out copper pipe 2, another system is that medium enters copper pipe 2 from right lower quadrant, goes out copper pipe 2 from upper right quarter；It is led when needing to increase During the refrigeration work consumption of machine, the power of simple system has certain limiting value, it is impossible to and it is unlimited to increase, therefore in same evaporator shell Left and right two systems are set in 1, so that having the refrigerating capacity of bigger in the volume of same evaporator.

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 outer 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 arranged for part along the 1 inner homogeneous spacing of shell Row, the discount vibram outlet of adjacent spoiler 5 are located at the horizontal left and right sides respectively, and forming the runner in the shell 1, left and right is snakelike to shake The passage of pendulum.

The heat exchanger channels of snakelike arrangement can enhance flow-disturbing and add heat exchange distance and area, improve heat exchange efficiency； Spoiler 5 is simple and reliable for structure, is easily installed and repairs, even if having compared with less breakage and crooked nor affecting on use；

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 0.8mm.
