966). If such a regulation line structure is used, favorable flow performance can be obtained, and there is an advantage that high heat collection efficiency can be obtained. However, while the effect of improving the heat collection efficiency can be obtained, the flow of the heat collection medium is hindered by the regulation line, and satisfactory results have not always been obtained for a low-temperature collector having a relatively large flow rate. In addition, when flowing down a heat collecting medium containing salt and inorganic components such as seawater and groundwater, a substance such as salt or calcium precipitates, and the deposits are deposited and hinder the flow of the heat collecting medium. There is. Furthermore, in the case of a heat collector with a large heat collecting surface, a large amount of heat collecting medium remains on the heat collecting surface even after the supply pump for the heat collecting medium stops, and a large load is constantly applied to the heat collecting surface. Not preferred.

集熱器の集熱面構造が得られる。According to the present invention, a large number of concaves are formed on a front surface of a sheet material constituting a heat collecting surface of a falling solar collector along a predetermined flowing direction of a heat collecting medium. The grooves are formed in parallel, and a heat collecting surface structure of a falling solar collector in which an absorbing layer of a heat collecting medium is adhered so as to cover at least an edge portion of the concave grooves is obtained.

Thus, the flowing heat collecting medium is restricted by the absorbing layer in the flowing direction, but the main body portion of the flowing heat collecting medium can flow smoothly. Therefore, a desired flow rate can be secured without precipitation of salt and inorganic components. Also, for a falling-type low-temperature collector in which the flow rate of the heat medium is set to be relatively large, the amount of the heat collection medium remaining adsorbed on the absorption layer is reduced, and a large amount of the heat collection medium is formed on the wide area heat collection surface. No large loading load is applied.
