PURPOSE:To improve the reliability of a U-shape pipe type solar heat collector by a method wherein a heat collecting panel is split into the panel for inlet side and the panel for outlet side of the heat medium for the U-shape heat collecting pipe to cut off the mutual interference between the low-temperature part of the heat medium inlet side and the high-temperature part of the heat medium outlet side and prevent generation of thermal deformation of the heat collecting panel. CONSTITUTION:Heat collecting panels 4A, 4B are attached to the area of heat medium inlet side and the area of heat medium outlet side separately and independently under being split at the boundary of the center of a heat collecting pipe 3. According to this constitution, the heat collecting panel 4A for the area of the pipe at the inlet side of the heat medium, whereat the low-temperature heat medium flows, and the heat collecting panel 4B of the area of pipe at the outlet side of the heat medium, whereat the high-temperature heat medium flows, are separated from each other and will never interfere thermally with each other, accordingly, the trouble of thermal deformation of the heat collecting panels due to thermal stress may be avoided. |
