The invention belongs to the field of solar collectors, and in particular relates to a novel high-seal solar collector of which a shell and a solar collector plate core are fixed in a punch molding way. The solar collector through punch forming consists of the solar collector plate core and the collector shell; and the inside of the collector shell is provided with a pipeline connected with the solar collection plate core. The solar collector through the punch forming is characterized in that: the shell has a shape corresponding to the shape of the solar collector plate core; the edge of the shell is turned over outwards; a folded edge for mounting pressing strips is formed on the periphery of the shell; the shell is molded by adopting a special mold and punching and bending a sheet metal; a protective plate made of a transparent material is covered on the upper part of the solar plate core; and the protective plate, the shell and the edge of the solar collector plate core are fixed into a whole through the pressing strips. The invention can provide the novel solar collector of which the shell and the solar collector plate core are fixed quite firmly.
