The dentation shown.Then, the first bending plate 331 and the second bending plate 332 are abutted each other, and the first groove 331c and the second groove
332c is aligned with each other, so as to can form a heat medium flow channel between every group of corresponding first groove 331c and the second groove 332c.
In addition, the first joint portion 331b is for example fixedly secured to one another by welding with the second joint portion 332b, and the first connection
Portion 331d and corresponding second connecting portion 332d are for example fixedly secured to one another by welding.In this way
Make to enclose heat medium flow channel between the first bending plate 331 and the second bending plate 332.
In the present embodiment, the cross sectional shape of the first groove 331c and the second groove 332c are triangle, thus can shape
It is diamond shape, rectangle or trapezoidal heat medium flow channel 34 at cross sectional shape.However, in other embodiments in accordance with the invention, it should
The shape of first groove 331c and the second groove 332c can also be rectangle or trapezoidal etc., thus can Formation cross-section shape be square
Shape, rectangular or irregular shape heat medium flow channel 34.
In the present embodiment, adjacent when the cross sectional shape of the first groove 331c and the second groove 332c are triangle
Two the first groove 331c intersect at the first intersection point；Two adjacent the second groove 332c intersect at the second intersection point；And first hands over
Point and the second intersection point are welded to one another.In addition, in the present embodiment, the first groove 331c can be set by the first bending section 331e and second
Bending section 331f is intersected each other to form, and the second groove 332c is intersected with each other by third bending section 332e and the 4th bending section 332f
It is formed.Then at this point, the angle between the first bending section 331e and the first bending plate 331 and the symmetry axis of the second bending plate 332 is excellent
It is selected as 30 °~60 °, and preferably 45 °.And the angle between third bending section 332e and above-mentioned symmetry axis is preferably again 30 °
~60 °, and preferably 45 °.
As Figure 7-9, in order to improve the heat exchange efficiency of thermal medium and water, in the present embodiment, in the first bending plate 331
It is further provided with the turbulent piece 36 of multiple length directions along shell spaced first, and on the second bending plate 332
It is further provided with the turbulent piece 37 of multiple length directions along shell spaced second, and in same heat medium flow channel 34
It is interior, it is also inserted with one first turbulent piece 36 between the two neighboring second turbulent piece 37 on the length direction of shell, is thus made
It obtains in each heat medium flow channel 34, the first turbulent piece 36 and the second turbulent piece 37 interval alternating with each other on the length direction of shell
Setting.Wherein, the flow direction of thermal medium can be as depicted by the arrows in figure 7.
Wherein, every one first turbulent piece 36 inclines from the side wall of the first bending plate 331 to corresponding heat medium flow channel middle part
Tiltedly extend.And every one second turbulent piece 37 prolongs from the side wall of the second bending plate 337 to the inclination of corresponding heat medium flow channel middle part
It stretches.
In the present embodiment, which includes the first mounting portion 361a and the first rake 361b.This first
Turbulent piece 36 by the first mounting portion 361a fitting be fixed on the first bending plate 331 (in the present embodiment, as shown in figure 9,
First mounting portion 361a can be fitted on the second bending section 331f when first groove shapes are triangle), and the first rake
361b is extended in the middle part of corresponding heat medium flow channel relative to the angled inclination of first mounting portion 361a.In the present embodiment,
Angle between the first rake 361b and the first mounting portion 361a is preferably 120 °~150 °, and preferably 135 °.
And the structure of the second turbulent piece 37 is similar with the first turbulent structure of piece 36, and the second turbulent flow piece 37 is from third bending
Section 332e extends to inclination in the middle part of corresponding heat medium flow channel.
Therefore, in the same heat medium flow channel 34, in the flow process of thermal medium, thermal medium can pass alternately between
One turbulent piece 36 and the second turbulent piece 37, thus make the thermal medium can produce rotation in the heat medium flow channel 34 and are formed disorderly
Stream, extends residence time of the thermal medium in heat medium flow channel 34, has greatly reinforced the thermal medium and has been located at water space 35
Thus the heat exchange efficiency of entire steam generator can be improved in heat exchange between interior water.
When processing steam generator, the metal plate of monolith (such as steel plate) bending is formed into corresponding first bending first
Plate 331 and the second bending plate 332, and it is combined into bending board group 33 by welding.Then by multiple bending board group 33
It is inserted on pedestal 311 respectively, and shell wall 312 is disposed around around bending board group 33.Then by water inlet adjacent
Water is poured into water space 35 between bending board group 33 and between shell wall 312 and bending board group 33, finally covers end cap 313
?.
When using the steam generator, temperature can be provided by heat source 32 first, medium is heated to generate heat
Medium (such as high temperature heat conductive oil or flue gas).When thermal medium flows through pedestal 311 and heat medium flow channel 34, thermal medium passes through first
The hydrothermal exchange of bending plate 331 and the second bending plate 332 and water space 35 is to obtain hot water or steam.Steam is such as obtained, then
Steam can be exported further by steam (vapor) outlet 312a, can thus be the steaming needed for subsequent equipment (such as gas combustion steaming cabinet) provides
Vapour；Hot water is such as obtained, the hot water can be made to be discharged by water outlet, to be recycled for subsequent.
Above-mentioned steam generator structure is simple, only needs time processing that can shape heat medium flow channel and water storage simultaneously
Space, it is convenient that the processing is simple.The form of multiple heat medium flow channels makes that the spacing between thermal medium and water is small and heat exchange area is big,
And the turbulent piece by being alternately obliquely installed further promotes the heat exchange between thermal medium and water, the thermal efficiency is high.
When using steam generator provided by the present invention, its offgas outlet temperature when using flue gas as thermal medium
Only 120 DEG C, far below offgas outlet temperature caused by steam generator shown in Fig. 1-3.In addition, its thermal efficiency may be up to
95%, and noise can be reduced to 50dB.It can be seen that the exhaust temperature that it is discharged using steam generator of the invention is lower,
Environmental pollution caused by due to high-temperature tail gas is discharged can be effectively prevented；In addition, its thermal efficiency is higher；The noise of generation is also significantly
It reduces.
The present invention still further provides a kind of gas combustion steaming cabinet, which uses above-mentioned steam generator to produce
Raw steam or hot water.
The embodiment of the present invention is described with above attached drawing, but the invention is not limited to above-mentioned specific
Embodiment, the above mentioned embodiment is only schematical, rather than restrictive, those skilled in the art
Under the inspiration of the present invention, without breaking away from the scope protected by the purposes and claims of the present invention, it can also make very much
