Abstract
The utility model discloses a kind of high-efficiency tank external finned tubes, it is characterised in that：Several grooves including being set to base tube outer surface form the fin of protrusion between two adjacent grooves, and there is equally distributed pointed sawtooth on the top of the fin.This outer fin heat-transfer effect after coil pipe is high, and can be mass, this external finned tube is higher than common external finned tube 7.2% ~ 95% by high-efficiency tank system test, production tube in follow-up coil pipe process heat exchange property.Its production method is simple, and production cost is low, convenient to carry out, and heat exchange property is again good, should generally be used by high-efficiency tank in the case where coal changes electric policy.
Description
Technical field
The utility model is related to a kind of heat exchanger thermal component, especially a kind of high-efficiency tank external finned tube.
Background technology
With continually developing for coal resources, energy shortage and environmental problem very severe, energy saving is to solve energy shortage
Important measures.As coal changes the continuous popularization of electricity, tank-type heat exchanger is quickly grown, and external finned tube is the important of tank-type heat exchanger
The quality of component, heat transfer property determines the performance of tank-type heat exchanger.Therefore, energy-efficient tank is studied with external finned tube to have
It is of great importance.
The general utilization of traditional finned tube is in straight pipe heat exchanger, and canned heat exchanger is needed with finned tube according to certain rule
It is coiled up, rear surface wing Internal and external cycle of traditional finned tube Jing Guo coiling can change a lot, and heat exchange property is opposite
Straight tube will appear decrease.Therefore it is significant to study a kind of energy-efficient outer fin wing coiled.
Invention content
For overcome the deficiencies in the prior art, the utility model provides a kind of high-efficiency tank external finned tube.
Technical solution adopted by the utility model to solve its technical problems is：
A kind of high-efficiency tank external finned tube, it is characterised in that：Several grooves including being set to base tube outer surface, two is adjacent
Groove between formed protrusion fin, there is equally distributed pointed sawtooth on the top of the fin.
Inner surface outside the pipe is equipped with internal thread.
The cross-sectional profiles shape of the fin is rectangle, and the height of fin is 0.85 mm~1.2mm.
The top of the fin is equipped with the axial groove axially opened up along base tube and the annular groove opened up along base tube surface annular,
The axial groove and annular groove are orthogonal.
The pointed sawtooth lines up two rows on the top of fin.
The width of the axial groove is 0.15 mm~0.35mm, and the depth of axial groove is 0.25 mm~0.45mm.
The width of the annular groove is 0.05 mm~0.15mm, and the depth of axial groove is 0.25 mm~0.35mm.
The cross section of the internal thread is triangle.
The utility model has the beneficial effects that：This outer fin heat-transfer effect after coil pipe is high, and can be mass, this
External finned tube is higher than common external finned tube by high-efficiency tank system test, production tube in follow-up coil pipe process heat exchange property
7.2%~95%.Its production method is simple, and production cost is low, convenient to carry out, and heat exchange property is again good, should be high in the case where coal changes electric policy
Effect tank generally uses.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the fragmentary isometric views of the utility model；
Fig. 2 is the surface close-up schematic view of the utility model.
Specific implementation mode
Referring to Fig.1, Fig. 2, the utility model discloses a kind of high-efficiency tank external finned tubes, including are set to 2 appearance of base tube
Several grooves in face form the fin 3 of protrusion between two adjacent grooves, and there is equally distributed pointed saw on the top of the fin 3
Tooth 4, the pointed sawtooth 4 uniformly line up two rows on the top of fin 3, and 3 external surface top of fin has equally distributed pointed saw
Tooth 4 is compared with common 3 pipe of fin, and pointed sawtooth 4 can make cooling medium liquid film make thinner, and liquid film can be dripped rapidly, heat transfer
Surface area has a very big promotion, and the pointed sawtooth 4 inner ring during coil pipe will appear and slightly reduce spacing, and outer ring can go out
The case where now slightly increasing spacing, makes the whole straight tube heat exchange property kept.
As shown, the inner surface outside the pipe is equipped with internal thread 1, the cross section of the internal thread 1 is triangle, interior spiral shell
Line 1 contributes to coil pipe to process, and improves coil pipe efficiency and lumber recovery.
As shown, the cross-sectional profiles shape of the fin 3 be rectangle, and the height of fin 3 be 0.85 mm~
1.2mm。
As shown, the top of the fin 3 is equipped with the axial groove 5 axially opened up along base tube 2 and along 2 surface of base tube annular
The annular groove 6 opened up, the axial groove 5 and annular groove 6 are orthogonal, the width of the axial groove 5 be 0.15 mm~
0.35mm, and the depth of axial groove 5 is 0.25 mm~0.45mm；The width of the annular groove 6 is 0.05 mm~0.15mm, and
The depth of axial groove 5 is 0.25 mm~0.35mm, and axial groove 5 and annular groove 6, axial groove 5 and annular groove 6 are arranged at 3 top of fin
Appearance makes heat transfer surface area be significantly increased；Heat dissipation effect is improved to whole.
A kind of high-efficiency tank outer fin 3 provided above the utility model embodiment is managed, and is described in detail, this
It applies specific case in text to be expounded the principles of the present invention and embodiment, the explanation of above example is
It is used to help understand the method and its core concept of the utility model；Meanwhile for those of ordinary skill in the art, according to this
The thought of utility model, there will be changes in the specific implementation manner and application range, in conclusion the content of the present specification
It should not be construed as a limitation of the present invention.
