Abstract
The present invention provides an antifreeze type heat collecting plate core and the production method thereof. The present invention adopts elasticity of the metal to increase size inside a pipe and protect pipe wall of a collecting pipe from the burst and freeze without anti-freezing of anti-freezing fluid. The present invention can be used in high-cold and ultra-cold regions, and has the advantages of simple production, long service life and low production cost, etc.
Description
Technical field the invention belongs to the heating equipment field, exactly is anti-freeze type heat collecting board core and manufacture method thereof.
The present plate solar collector of background technology generally uses pipe/board-like heat-collecting plate core, and direct water is as the thermal-arrest medium, when environment temperature is lower than below 0 ℃ in the pipe, tend in the pipe freeze, tube wall is burst in volumetric expansion, has influenced the normal use of flat plate collector.
Summary of the invention task of the present invention is that the collector tube wall of flat plate collector is made the ripple tube wall, has solved a difficult problem of bursting heat-collecting plate core because of freezing and expansion.
In order to realize above-mentioned task, anti-freeze type heat collecting board core of the present invention is made of collector, comb, heat absorption band.The collector tube wall of anti-freeze type heat collecting board core is made bellows wall; when in the collector during water freezing; volumetric expansion; the volume that expands can the extruded manifold tube wall be the ripple tube wall, and the ripple wall compression stretches, and has guaranteed that so just the pressure in the collector tube wall can not surpass the ultimate bearing pressure of collector tube wall; after ice dissolves; because the elastic force of ripple tube wall returns to original shape again, thereby has protected the collector tube wall of heat-collecting plate core can not burst freezing because of water freezing in the collector.
Advantages such as characteristics of the present invention: adopt metallic elastic to increase the pipe internal volume, do not need anti-icing fluid antifreeze, protection collector tube wall is not burst freezing, can use in high and cold, extremely cold area, has and makes simple, long service life, and cost of manufacture is low.
Description of drawings is done further detailed elaboration below in conjunction with accompanying drawing to the present invention:
Fig. 1 is anti-freeze type heat collecting board core collector of the present invention, comb cutaway view and cross-sectional view.
Fig. 2 is that ripple tube wall of the present invention adopts mould drawing and forming longitudinal sectional view.
Fig. 3 is the view in transverse section that collector of the present invention is drawn into axial ripple tube wall.
1. collector 2. combs 3. heat absorption bands 4. ripple tube walls 5. pipe mouths 6. comb holes 7. mould plugs, 8. pipe walls.
The specific embodiment as shown in Figure 1, anti-freeze type heat collecting board core of the present invention is made of collector 1, comb 2, heat absorption band 3.It is ripple tube wall 4 that the round collector 1 stage casing part of anti-freeze type heat collecting board core is made the corrugated tube wall, the bellows wall part accounts for one of four parts of pipe cross circular section circumferential portion above angle [alpha], the total length of ripple tube wall (4) axial wave tube wall section is 200-2000mm, the pitch of waves of ripple tube wall (4) is 1-10mm, the mouth of pipe is a pipe mouth 5, again collector 1, comb 2 is carried out soldering group and dresses up anti-freeze type heat collecting board core; In collector 1, make water as the thermal-arrest medium, when environment temperature is lower than below 0 ℃, water can freeze in anti-freeze type heat collecting board core in order, water in the collector 1 freezes at last, volumetric expansion when freezing, the volume that expands can extruded manifold 1 tube wall be a ripple tube wall 4, ripple tube wall 4 pressurizeds stretch collector 1 internal volume are increased, the ice that expands has had the volume part, alleviated the pressure of collector 1 tube wall, so just, guaranteed only to have less pressure in collector 1 tube wall, can explosion because of the ultimate bearing pressure that surpasses collector 1 tube wall.After ice dissolves,, thereby protected collector 1 tube wall of anti-freeze type heat collecting board core can not burst freezing because of water freezing in the collector 1 because the elastic force of ripple tube wall 4 returns to the shape of original ripple tube wall 4 again.
Adopt the mould drawing and forming to make the method one of anti-freeze type heat collecting board core collector 1:
By Fig. 1 to 2 as can be known, the collector 1 of anti-freeze type heat collecting board core of the present invention adopts the round tube material, during mould drawing and forming ripple tube wall (4), hold collector 1 successfully comb hole 6, the mould plug 7 of again the 1-2 root having been manufactured corrugation grooves inserts from two of collector 1 that (corrugation grooves contacts in the stage casing in the collector 1, two is circular), adopt forcing press, mould is with the axial corrugated of stage casing part drawing and forming, the corrugated tube wall of making is a ripple tube wall 4, the mouth of pipe also keeps pipe mouth 5, extract out from two with mould plug 7 then, make the stage casing and have ripple tube wall 4, the mouth of pipe is the collector 1 of pipe mouth 5.
Adopt and draw the method two that axial corrugated header is made anti-freeze type heat collecting board core collector 1:
By Fig. 1 to 3 as can be known, the collector 1 of anti-freeze type heat collecting board core of the present invention is when drawn tube, by corrugated header 4 shape of cross sections and need the angle of bellows wall part, be drawn into axial bellows, corrugated header 4 is cut into the length that collector 1 needs, hold collector 1 successfully the comb hole after, the mouth of pipe of corrugated header 4 is manufactured be pipe mouth 5 again, be convenient to connect, make promptly that the stage casing has ripple tube wall 4, two mouth of pipe is the collector 1 of pipe mouth 5 with outer water pipe.
