Abstract
The present invention relates to a kind of novel spiral heat exchangers.New type helical plate heat exchanger of the invention forms the closed cylinder with two medium channels being separated including being rolled by two metal plates, cylinder side is provided with the medium inlet communicated respectively with two passes and media outlet.Cylinder body bottom is provided with corresponding medium inlet and media outlet.Punching press preprocessing is carried out to one of metal plate, is become by successively alternate contraction section, the scaling plate of expansion segment and parallel-segment composition.It scales and uses arc transition at tip, and be all made of arc transition in the transition region and expansion segment of parallel-segment and contraction section and the transition region of parallel-segment.Spacing column is set between two blocks of spiral plates, to guarantee the rigidity, stability and intensity of spiral plate.New type helical plate heat exchanger provided by the invention, the characteristics of combining spiral heat exchanger, shaped telescopic tube, heat exchange area is bigger, compact-sized, heat transfer efficiency is higher and the processing is simple.
Description
Technical field
The present invention relates to a kind of novel spiral heat exchangers, belong to heat exchange equipment technology.
Background technique
Spiral heat exchanger rolls into two helix-type channels by two parallel metal sheets, and cold and hot two kinds of heat transfer mediums are logical
It crosses spiral wooden partition to exchange heat, and in order to improve the bearing capacity of spiral heat exchanger, on every metal plate all equably
It is welded with spacing column.Spacing column is equably housed between plate, is on the one hand played a supporting role, disturbing for fluid is on the other hand also strengthened
It is dynamic, achieve the purpose that enhanced heat exchange.Traditional spiral heat exchanger is as using the heat exchange of spiral made of two flat metal plates
Plate, therefore the problems such as that there is heat transfer areas is small, and heat exchange efficiency is not high.
Summary of the invention
It is an object of the invention to propose that a kind of heat transfer efficiency is high, compact-sized, the processing is simple Novel spiral is board-like to change
Hot device.
The technical measures that the present invention uses are become to carry out preprocessing one of in traditional parallel metal sheet
By successively alternate contraction section, the scaling plate of expansion segment and parallel-segment composition.Fluid flow velocity in expansion segment reduces, static pressure increases
Add；And flow velocity increases in contraction section, static pressure reduces, and the whirlpool that expansion segment generates can be effectively utilized in contraction section, and
Fluid boundary layer is washed away, boundary layer is thinned, and enhances heat transfer.Therefore it can not only increase heat transfer area, and can be improved
Turbulence effects inside heat exchanger enhance the heat exchange efficiency of spiral heat exchanger.
It is equipped with spacing column between two pieces of heat exchanger plates, ensure that the spacing of two pieces of heat exchanger plates is stablized, while can also play and disturb
The effect of stream.
Scaling groove of the invention is processed using stamping technology.To prevent point stresses from concentrating, used at scaling tip
Arc transition is to reduce local stress, and in the transition region of the transition region and expansion segment of parallel-segment and contraction section and parallel-segment
It is all made of arc transition.
Increase by the one section of installation site of parallel-segment as spacing column between expansion segment and contraction section.
Through the above technical solutions, medium can be made to flow, be more fully mixed in the heat transfer process in channel, raising is changed
The thermal efficiency.
Compared with prior art, new type helical plate heat exchanger provided by the invention, heat exchange area is bigger, and structure is tight
It gathers, heat transfer efficiency is higher and the processing is simple.
