Abstract

In a process for the production of a solar collector panel assembly, a pipe arrangement for carrying a heat exchange fluid and a carrier panel for carrying same and for absorbing solar energy are intimately jointed together as by soldering or brazing. The pipe arrangement has straight pipe sections and curved pipe sections connecting same. A joining agent such as solder is applied to the carrier panel along the lines of the pipe arrangement, and the pipe arrangement is then applied thereto. A filling material comprising a substance which repels the joining agent is disposed in the spaces defined between the pipe runs of the pipe arrangement. The intermediate assembly consisting of carrier panel, joining agent, pipe arrangement, filling material and possibly a heat barrier layer disposed on the side of the assembly remote from the carrier panel is fitted between two pressure plates which are clamped together. Heat applied at least to the side of the assembly at which the carrier panel is disposed causes the joining agent to fuse, thereby securing the pipe arrangement to the carrier panel, with the pipe arrangement being pressed into the bed of joining agent by the pressure applied by the pressure plates.
