Flat solar energy heat-absorption fin

Abstract

The invention relates to a flat solar energy heat-absorption fin. Compared with the traditional whole plate or stripe, the fin provided by the invention is characterized in that the cross section of the fin provided by the invention is V-shaped, the included angle of the V shape is 8-15 degrees, the thickness of the fin is 0.5-0.9mm, and the whole fin expansion length is 90-110mm. Compared with the common stripe, the fin provided by the invention has the advantage that the heat absorption area is increased by 1.2 times, thereby enhancing the heat efficiency of a heat collector. In addition, one side of the fin is provided with an inlaying groove, the other side of the fin is provided with an inlaying part matched with the inlaying groove, and the tail end of the inlaying part is provided with an arc-shaped bulge, thus the adjacent fins can be conveniently connected into a whole by depending on the self-locking function of the inlaying groove in the assembling course, and the bidirectional transmission of heat can be achieved conveniently, while the traditional fin does not have such two structural advantages.

Description

technical field [0001] The invention relates to a solar heat absorbing fin, in particular to a flat solar heat absorbing fin. Background technique [0002] At present, at home and abroad, there are mainly two types of fin structures: the whole plate or the strip. The whole plate is a metal plate, the surface is a plane, and its area is the area of ​​the plane, and the strip is the whole plate cut into pieces. Several small strips have a smaller area, and there is no contact between two adjacent strips, and there is no heat conduction, which is not conducive to the heat conduction on the fins, thereby affecting the thermal efficiency of the entire collector. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned deficiencies in the prior art, and provide a flat solar heat absorbing fin with good heat transfer effect, large heat absorbing area, self-locking function, and favorable bidirectional conduction of heat.
