Summary of the invention
Technical problem to be solved in the utility model is the shortcoming that overcomes prior art, provides a kind of saving of labor, material-saving also can effectively improve the flow passage structure of the wall hanging type flat plate solar thermal collector of the thermal efficiency.
The technical scheme that the utility model adopted is: a kind of wall hanging type flat plate solar thermal collector comprises glass, frame, heat-absorbing plate core, heat-insulation layer and backboard; Described heat-insulation layer is arranged on the inner peripheral of backboard and frame, the heat-insulation layer of described backboard is provided with heat-absorbing plate core, described glass plate is arranged on the top of heat-absorbing plate core, is embedded in the described frame, and described heat-absorbing plate core comprises band, collector, MEDIA FLOW inlet and MEDIA FLOW outlet; Described band is transversely arranged, and described collector is arranged on the two ends, the left and right sides of band, and logical by being weldingly connected with the collector of left and right sides.
Described MEDIA FLOW inlet is connected by the band of collector with plate core below, and described MEDIA FLOW outlet is connected by the band of collector with plate core top.
The band number that the band number that described MEDIA FLOW inlet is connected with plate core below by collector is connected with plate core top by collector less than described MEDIA FLOW outlet.
The length of described band is greater than the length of collector.
The beneficial effects of the utility model are: under the constant situation of plate solar area, with the band horizontally set, prolonged the circulating path of heating, heat output is improved, the minimizing of band quantity has reduced welding and has counted, reduce the leakage ratio, saved raw material owing to reduced the length of collector again, effectively saved manufacturing cost.
