を通水管に密着させることよりなるものである。In the method for manufacturing a solar water heater according to the present invention, a heat collecting plate having a solar heat absorbing film on the upper surface and a required number of grooves is arranged at a predetermined interval above the bottom wall of a water heater case. Insert the water pipe loosely into the groove, inject and foam a foamed resin insulation material between the bottom wall of the water heater case and the heat collecting plate, and use this foamed LF to connect the water pipe to the groove wall. It consists of making them come into close contact.

熱吸収膜を形成してもよい。In order to provide the heat collecting plate, for example, made of aluminum (the upper surface of which absorbs solar heat), it is preferable to apply a solar heat selective absorption film treatment to the surface of the heat collecting plate, for example. The solar heat selective absorption film preferably has a solar absorption rate α of 0.85 or more and an emissivity ε of 0.3 or less. Incidentally, the solar heat selective absorption film is generally smooth, but in order to increase the surface area, it may have a finely wavy longitudinal section. Alternatively, a solar heat absorbing film may be formed by applying black coating to the surface of the heat collecting plate.

管などが用いられる。In order to form the required number of grooves on the upper surface of the heat collecting plate, the heat collecting plate is made into a substantially corrugated plate shape, for example. The thickness should be similar to that of the heat collector plate. As the water pipe, aluminum pipes, steel pipes, steel pipes, etc. are used.

ものになる。As described above, according to the manufacturing method of this invention, the water pipes can be attached to the heat collecting plate by injection and foaming of a foamed resin heat insulating material, so the work is easy. However, since the heat collecting plate and the water pipe are brought into close contact with each other due to the foaming pressure, the bond between the two becomes strong. In addition, in the water heater obtained by this method, the groove wall of the heat collecting plate provided with the solar heat absorbing film is brought into close contact with the outer peripheral surface of the water pipe, so that the heat transfer between the two is excellent. Furthermore, in the process of using this water heater, when the heat insulating side is heated, it causes secondary foaming, so that the connection between the heat collecting plate and the water pipe becomes even stronger.
