Description
Technical field
The present invention relates to refrigeration system technical fields, and in particular to it is a kind of with efficient automatic defrosting around piece heat exchanger.
Background technology
In large-scale freezing and refrigeration ammonia refrigeration system, it is cold in evaporator using steel pipe around plate evaporator, when cold
Interior air blows over evaporator, and air themperature is less than zero Celsius temperature, heat exchange pipe external surface frosting, with the increase of frost layer, evaporation
The thermal resistance of device increases, and heat transfer temperature difference increases, and evaporating temperature reduces, and the pressure ratio of refrigeration compressor increases, and power consumption increases, refrigeration system
The performance of system declines.

Fixed, other end connecting rod, the outside that the pull rod stretches out in outline border are connect with the pulling plate being located on the outside of outline border, the pulling plate
It is connect with bent axle by connecting rod, the bent axle is connect with motor.
The outline border is welded by four sides steel plate up and down and is formed, wherein left side steel plate correspond to pull rod quantity open up it is multiple
Perforation, for passing through for the pull rod.
The end point solid welding around piece is scheduled on heat exchanger tube one end, and one end of the other end and the pull rod is welded.
The motor is fixed on the external part of bottom steel plate of the outline border, the main shaft of the motor and the main shaft of bent axle
Be fixedly connected by shaft coupling, the crank-pin of the bent axle and one end of connecting rod rotatably coordinate, the other end of the connecting rod with
The center of the pulling plate is fixedly connected.
The automatic defrosting of the present invention around piece heat exchanger, driven using automatic moving mechanism and moved in heat exchange pipe surface around piece
It is dynamic, it can prevent the frost layer outside heat exchanger tube from assembling solidification, reduce the thermal resistance of evaporator, reduce heat transfer temperature difference, reduce refrigeration compressor

Description of the drawings
Fig. 1 show the structural schematic diagram around piece heat exchanger of the automatic defrosting of the present invention；
Fig. 2 is shown as the sectional view along A-A of Fig. 1.
Specific implementation mode
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.
As depicted in figs. 1 and 2, the schematic diagram around piece heat exchanger of automatic defrosting, including：
Outline border 1, heat exchanger tube 2, around piece 3, motor 4, bent axle 5, connecting rod 6, pulling plate 7, pull rod 8；
The outline border 1 is welded to form by four sides steel plate up and down, and corresponding to pull rod 8 on the steel plate of left side opens up multiple wear
Hole, described made by sheet metal around piece 3 are formed, and the right side end point solid welding around piece is scheduled on heat exchanger tube right-hand end, at spiral
Shape is wound on outside heat exchanger tube, and another left-hand end and one end of pull rod 8 are welded, and the other end of pull rod 8 passes through the left side of outline border 1 corresponding
Aperture is fixedly connected with pulling plate 7.
Wherein, the sheet body around the strip that piece is the metal material with one fixed width, is wrapped in heat exchanger tube
On medial surface be in contact with the outside wall surface of heat exchanger tube, winding arrangement be similar to screw conveyor helical blade winding cloth
Structure is set, the frost on the surface except heat exchanger tube is realized by the contact activity around piece with heat exchanger tube.
The motor 4 is fixed on the external part of the bottom plate of outline border, and the main shaft of motor 4 passes through shaft coupling with the main shaft of bent axle 5
It is fixedly connected, the crank-pin of bent axle 5 rotatably coordinates with one end of connecting rod 6, the center of the other end and pulling plate 7 of connecting rod 6
It is fixedly connected.
Wherein, the fan (not shown) of the evaporator can be fixed on the edge of outline border, and wind direction should be in heat exchanger tube
Vertical direction.
After frosting outside the heat exchanger tube of evaporator, start motor 4, the main shaft band dynamic crankshaft 5 of motor 4 rotates, and drives connecting rod 6
It swings, drives pull rod 8 to move left and right by pulling plate 7, make to move around piece 3, to realize the frost layer for striking off heat exchange pipe external surface, and
It is blown down through fan, after frost layer is removed, stops motor.
The above is only a preferred embodiment of the present invention, it is noted that for the common skill of the art
For art personnel, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications
Also it should be regarded as protection scope of the present invention.
