Abstract
The utility model discloses a high -efficient compound heat exchange tube of reinforceing, including heat transfer body and the twisted strip of setting in the internal portion of heat exchange tube. The heat transfer body is spiral corrugation pipe, bellows, band pipe, cyclone tube, the flat pipe of spiral, scale a kind in the pipe. Is heat transfer body diameter 16 57mm. Be it 2 to have opened the diameter in the heart in the twisted strip pitch of the internal portion of heat exchange tube 5mm's hole. Through trompil in the heart in the twisted strip pitch, new passageway is provided for the fluid to lower the flow of fluid resistance, reached and both improved coefficient of heat transfer, reduced the dual effect of flow resistance again.
Description
Technical field
This utility model relates to a kind of heat exchange element, especially a kind of shell-and-tube heat exchanger augmentation of heat transfer pipe.
Background technology
Fast development along with heat transfer enhancement technology, heat transfer enhancement technology has started to be applied to the fields such as petrochemical industry, power, metallurgy, Refrigeration Engineering, in recent years, people have begun to study Combination Intensified Heat Transfer Technology, so-called Combination Intensified Heat Transfer Technology, two or more enhancements i.e. is applied simultaneously, to obtaining the technology of the biggest heat conduction reinforced effect.But after employing Combination Intensified Heat Transfer Technology, heat exchanger is while adding heat transfer coefficient, and its resistance coefficient increases the most therewith, and therefore Combination Intensified Heat Transfer Technology is restricted in the application in market.
Summary of the invention
This utility model provides a kind of simple in construction, easy to process, the compound intensified heat-transfer pipe of function admirable.To this end, the technical solution adopted in the utility model is as follows:
This utility model mainly includes heat exchange tube body and is arranged on the twisted strip within heat exchange tube body.Described heat exchange tube body is the one in spirally corrugated tube, corrugated tube, band pipe, cyclone pipe, spiral flat tube, shaped telescopic tube.The a diameter of 16-57mm of described heat exchange tube body.Twisted strip pitch within described heat exchange tube body has the hole of a diameter of 2-5mm in the heart.
This utility model is achieved through the following technical solutions:
A kind of high efficiency composition thermoexcell, including heat exchange tube body be arranged on the twisted strip within heat exchange tube body.Described heat exchange tube body is the one in spirally corrugated tube, corrugated tube, band pipe, cyclone pipe, spiral flat tube, shaped telescopic tube.The a diameter of 16-57mm of described heat exchange tube body.Twisted strip pitch within described heat exchange tube body has the hole of a diameter of 2-5mm in the heart.
The present invention has significant advantage and a positive effect:
This utility model, by being inserted into twisted strip at thermoexcell, makes tube fluid produce and rotates and cause Secondary Flow, attenuated layer laminar sublayer thickness, and make axial speed field homogenization, reach augmentation of heat transfer effect.By perforate in the heart in twisted strip pitch, provide new passage to fluid, thus reduce the flow resistance of fluid, reached both to improve heat transfer coefficient, reduced again the double effects of fluid resistance.
Accompanying drawing explanation
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is a kind of high efficiency composition thermoexcell schematic diagram.
In figure, 1-heat exchange tube body, 2-twisted strip.
Detailed description of the invention
In order to be better understood from this utility model, below in conjunction with the accompanying drawings this utility model is further described.As it is shown in figure 1, a kind of high efficiency composition thermoexcell, including heat exchange tube body be arranged on the twisted strip within heat exchange tube body.Described heat exchange tube body is the one in spirally corrugated tube, corrugated tube, band pipe, cyclone pipe, spiral flat tube, shaped telescopic tube.The a diameter of 16-57mm of described heat exchange tube body.Twisted strip pitch within described heat exchange tube body has the hole of a diameter of 2-5mm in the heart.
