Abstract
The utility model discloses a heat collecting plate of a solar flat plate collector. The heat collecting plate comprises a heating collecting plate body. Two mutually parallel empty cavities are arranged in the heating collecting plate body. The empty cavities and the heat collecting plate body are molded as a whole so that mutually parallel tubular flow channels are formed. The upper surface of the heat collecting plate body is coated or plated with a selective absorption coating. The heat collecting plate body is an aluminium alloy heat collecting plate body which is molded by extrusion. Cross sections of the tubular flow channels are square, rectangular, circular or elliptical. Two sides of the heat collecting plate body are respectively provided with connection joints used for splicing adjacent two heat collecting bodies as a whole. The connection joints at the two sides of the heat collecting plate body are respectively a protruding head and a connection notch. Or the connection joints at the two sides of the heat collecting plate body are respectively an upper connection hook and a lower connection hook. The heat collecting plate of the solar flat plate collector is simple in structure, low in cost, high in heat exchange efficiency and long in service lifetime.
Description
Technical field
The utility model relates to a kind of plate solar collector, relates in particular to a kind of collecting plate of plate solar collector.
Background technology
The heat-collecting strip of flat plate collector is the core component of panel solar, and its thermal efficiency to panel solar plays critical effect.Using commonplace heat-collecting strip structure type both at home and abroad at present is tube-sheet type and wing pipe type.The tube-sheet type heat-collecting strip is that copper pipe and heat absorption fin are formed to heat-collecting strip by laser weld or ultrasonic bonding.Contacting between the heat absorption fin on circular copper pipe and plane is straight line, and its contact area is little, and thermal resistance is large, is unfavorable for the exchange of heat, thereby has affected the efficiency of whole heat collector.The compound heat-collecting strip of copper aluminium is wing pipe type, it can solve the problem that contact area is little, but this structure is by external force, copper pipe and the aluminium wing to be pressed together, and major part is physical contact, due to the pressing that is different materials, the coefficient of thermal expansion and contraction difference, so expand with heat and contract with cold for a long time, the two contact area can progressively diminish, thereby causes collecting efficiency to descend, this heat-collecting strip is difficult to accomplish fully smooth when being assembled into heat-collecting plate core in addition, affects the outward appearance of flat plate collector.
The utility model content
The purpose of this utility model is to provide a kind of collecting plate of plate solar collector, and the collecting plate of this plate solar collector is simple in structure, cost is low, heat exchange efficiency is high, long service life.
For realizing above-mentioned technical purpose, the technical scheme that the utility model is taked is: a kind of collecting plate of plate solar collector, comprise the collecting plate body, and it is characterized in that: be provided with at least two cavitys parallel to each other in described collecting plate body; Described cavity and this body by integral forming of collecting plate, form tubulose runner parallel to each other; The upper surface of described collecting plate body scribbles or is coated with coating for selective absorption.
As the further improved technical scheme of the utility model, the aluminium alloy collecting plate body that described collecting plate body is extrusion modling.
As the further improved technical scheme of the utility model, the cross section of tubulose runner is square, rectangle, circle or oval.
As the further improved technical scheme of the utility model, the both sides of described collecting plate body are respectively equipped with for two adjacent collecting plate bodies being spliced into to the connecting interface of an integral body.
As the further improved technical scheme of the utility model, the connecting interface of the both sides of described collecting plate body is respectively and connects plush copper and be connected recess.
As the further improved technical scheme of the utility model, the connecting interface of the both sides of described collecting plate body is respectively butt hook and lower butt hook.
Compared with prior art, advantage has the utility model: 1, the utility model adopts collecting plate to replace traditional heat-collecting strip, and because runner quantity is multiplied, heat exchange area also is multiplied, and has greatly improved heat exchange efficiency; 2, the coating for selective absorption on the upper surface of collecting plate in the medium in the tubulose runner, is compared the heat direct heat transfer of solar energy conversion with heat-collecting strip, has not had by fin to the heat transfer resistance comb, and heat-transfer path is the shortest, heat transfer efficiency is the highest; 3, collecting plate is the commaterial extrusion modling, is an integral body, does not have the coefficient of thermal expansion and contraction difference due to different materials, and the latter two contacts area can progressively diminish for a long time, thereby the problem that causes collecting efficiency to descend, has greatly extended service life; 4, the both sides of collecting plate are provided with left connecting interface and right connecting interface, pass through connecting interface, adjacent plate more than two or two can be spliced into mutually as a whole, the left connecting interface on collecting plate matches with the right connecting interface of another collecting plate, thereby makes the outward appearance of flat plate collector more attractive in appearance; 5, replace the copper of high price with cheap aluminium alloy, greatly saved cost.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is provided with to connect plush copper and the collecting plate structural representation that is connected recess.
Fig. 3 is the collecting plate structural representation that is provided with butt hook and lower butt hook.
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further.
