Abstract
The utility model relates to a solar flat plate collector which comprises a plurality of pipe vane type heat absorption plate strips arranged in parallel. Each pipe vane type heat absorption plate strip comprises a metal plate strip, a copper pipe and a fixed metal plate strip. A groove is arranged on the central axis of the metal plate strip, wherein the cross section of the groove is arc; the diameter of the groove is the same with the outer diameter of the copper pipe; the fixed metal plate strip comprises an extruding part and two vanes arranged at the two sides of the extruding part, wherein the cross section of the extruding part on the length direction of the extruding part is arc; the diameter of the extruding part is the same with the outer diameter of the copper pipe; the extruding part and the groove of the metal plate strip are opposite to form a round pipe type holding space; the two vanes are respectively welded and fixed with the metal plate strip; the copper pipe is arranged in the round pipe type holding space and is tightly fit with the inner wall of the extruding part and the inner wall of the groove. As a pipe vane structure is adopted on the heat absorption plate strip of the solar flat plate collector, the heat transfer efficiency is high, and the heat absorption plate strip can be welded firmly.
Description
Technical field
The utility model relates to the Application of Solar Energy field, especially relates to a kind of plate solar collector.
Background technology
At present, what plate solar collector application both at home and abroad was the widest is the copper-aluminum composite board core, and the absorber of this plate core is the compound heat absorption lath of copper aluminium.As shown in Figure 1, the copper pipe 2 on the laths of metal 1 that this heat absorption lath comprises aluminum and the axis that is welded in this laths of metal one side, this copper pipe 2 is connected with the line that is connected between this laths of metal 1, and is firm inadequately; Contact-making surface is little between copper pipe 2 and the laths of metal 1, and heat transfer area is little; The fusing point of copper and aluminium is different in addition, and the thickness of the thickness of copper pipe 2 and aluminum lath 1 is also different, is easy to take place rosin joint, causes the two loose contact, thereby it is bad to cause conducting heat.Also the someone adopts the method welding copper pipe and the aluminium sheet of Laser Welding, but effect is just better than traditional welding method, can not solve the problem of rosin joint at all, and welding cost is high.Another defective of prior art is: laths of metal is a slab construction, and it will shine easily in its surperficial sunshine and reflect away, and makes this part heat energy can not get using.
To sum up, be necessary the plate solar collector that provides a kind of heat-transfer effect good.
The utility model content
In view of this, be necessary a kind of raising copper pipe and laths of metal contact-making surface to be provided, to make both combinations more firm, and can significantly improve the plate solar collector of heat transfer efficiency and heat energy utilization rate to the problem of mentioning in the background technology.
The purpose of the utility model realizes through following technical scheme:
A kind of plate solar collector; It is characterized in that; Comprise many tube wing type heat absorption laths that laterally arrange; Each tube wing type heat absorption lath comprises a laths of metal, a copper pipe and a metal security strip, and the axis of said laths of metal is provided with the groove that a cross section is an arc, and the diameter of this groove is identical with the outside dimension of described copper pipe; Said metal security strip comprises along the cross section of its length direction being the protuberance and two fins that are arranged at these protuberance both sides of arc; The diameter of this protuberance is identical with the outside dimension of said copper pipe; The groove of this protuberance and said laths of metal constitutes a tubular type receiving space relatively; This two fin is fixing with this laths of metal welding respectively, and said copper pipe is arranged in the said tubular type receiving space, fits tightly with the inwall of said protuberance and the inwall of said groove.
Said laths of metal is provided with many thermal-arrest grooves.
The cross section of the protuberance of the groove of said laths of metal and said metal security strip is semicircle.
Said laths of metal is aluminium matter, copper or albronze lath, and said metal security strip is aluminium matter, copper or albronze security strip.
Said laths of metal is identical with the thickness of said metal security strip.
Compared to prior art, the advantage of the utility model is:
1, copper pipe and laths of metal contact-making surface are big, and heat-transfer effect is good;
2, the fin of laths of metal and metal security strip welding, the two is the face connection, firm welding is difficult to occur the situation of rosin joint;
3, laths of metal is identical with the thickness of metal security strip, and material is identical, has further guaranteed welding quality;
4, laths of metal is provided with groove, and the surface is not smooth, and projection sunshine on it repeatedly reflects through male and fomale(M&F), can increase the heat energy utilization rate.

Fig. 1 is the cross sectional representation of prior art;
Fig. 2 is the cross sectional representation of the utility model embodiment.
The specific embodiment
The plate solar collector of present embodiment comprises many tube wing type heat absorption laths that laterally arrange; As shown in Figure 2; Each tube wing type heat absorption lath comprises laths of metal 10 and copper pipe 20; It is semicircular groove 11 that the axis of said laths of metal 10 is provided with a cross section, and the diameter of this groove 11 is identical with the outside dimension of said copper pipe 20; Each tube wing type heat absorption lath also comprises a metal security strip 30 identical with the length of said laths of metal 10; It comprises that along a cross section of axis be semicircular protuberance 31 and two fins 32 that are arranged at these protuberance both sides; The diameter of this protuberance 31 is identical with the outside dimension of said copper pipe 20; The groove 11 of this protuberance 31 and said laths of metal 10 constitutes a tubular type receiving space relatively; This two fin 32 welds with this laths of metal 10 respectively, and said copper pipe 20 is arranged in the said tubular type receiving space, and fits tightly with the inwall of said protuberance 31 and the inwall of said groove 11.
Said laths of metal 10 is not smooth, also is provided with many thermal-arrest grooves 12 that extend along axis direction on it.
The material of said laths of metal 10 and said metal security strip 30 is aluminium, and the thickness of the two is identical.
Design according to the utility model can also have following distortion:
The cross section of the cross section of the groove of said laths of metal and said metal security strip is circular arc, and one of them is a major arc, and another is a minor arc, and the diameter of the two is identical; The material of said laths of metal 10 and said metal security strip 30 can also be copper, albronze.
The thermal-arrest groove of said laths of metal can perhaps be direction extension at any angle along other and axis direction along extending perpendicular to axis direction.
The above embodiment has only expressed several kinds of embodiments of the utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model patent should be as the criterion with accompanying claims.
