Description
Technical field
This utility model relates to heat transmission equipment, refers to a kind of stagger arrangement integral type extended surface tube group especially.
Background technology
In various types of heat transmission equipments of the industry such as the energy, chemical industry, pipe heat exchanger is the most
Conventional one.Heat exchanger tube uses extended surface tube, heat exchange area can be significantly increased, be enhanced heat exchange
Effective ways.Generally heat exchanger tube has in-line and two kinds of arrangement modes of stagger arrangement.Tube bank uses stagger arrangement
Arrangement, air-flow between pipe in the bending channel of alternating contractions and expansion flow, than in-line time
Between pipe, the flow disturbance of corridor is the most violent, and therefore heat transfer effect is higher.
Conventional extended surface tube has spiral type extended surface tube and H type extended surface tube, wherein spiral type extended surface tube
Can only be single base tube structure, and H type extended surface tube can be made into the pipe group of many base tubes structure,
Common double-basis tubular construction, i.e. Dual-H-type finned tube.
Single base tube extended surface tube can use in heat transmission equipment and be staggered in arrangement to improve heat transfer effect, but
Its production efficiency is relatively low.H type many base tubes extended surface tube group is effectively increased production efficiency, but existing
In H type many base tubes extended surface tube group, base tube uses in-line arrangement mode, under equal conditions, changes
Thermal effect is not as the single base tube finned-bundles being staggered in arrangement.
Utility model content
The purpose of this utility model is to propose the existing in-line arrangement H type many base tubes fin of a kind of raising
Sheet pipe group heat exchange efficiency is provided simultaneously with the stagger arrangement integral type extended surface tube group of relatively high efficiency.
This utility model is realized by following technical scheme:
Stagger arrangement integral type extended surface tube group, including horizontal fin；Described horizontal fin upper and lower side is fin
Sheet minor face；Described horizontal fin left and right sides is fin foreign minister limit；Described horizontal fin includes left side
Laterally fin and the horizontal fin in right side；The horizontal fin of the horizontal fin in described left side and described right side is altogether
Face is arranged；On the right side of the horizontal fin in described left side and be inside fin on the left of the horizontal fin in described right side
Long limit；The horizontal fin of the horizontal fin in described left side and described right side is clamped with some foundation pipes.
Adjacent two foundation pipe center of circle tie lines are 30 ° with the angle α of described fin minor face
～75 °.
Described base tube is provided with 2 or 4.
Described fin foreign minister limit is linear type or sawtooth broken line type or flat tooth broken line type.
Described base tube upper and lower side is additionally provided with longitudinal fin, described longitudinal fin and described horizontal fin
Sheet is mutually orthogonal；Inside described fin, long limit is long limit inside flat tooth broken line type, and described fin
Each section of broken line length be described base tube external diameter and two panels longitudinal direction fin height sum, described
Fin foreign minister limit is flat tooth broken line type.
Adjacent two foundation pipes are staggered in arrangement by this utility model, increase effective heat exchange area, carry
High heat exchange efficiency, fin foreign minister limit is designed with multiple version type to adapt to the demand of different operating mode,
And be designed with longitudinal fin and increase heat exchange area further.
