表面構造に係る。Detailed Description of the Invention (Industrial Application Field) The present invention relates to improvements in a heat exchanger that receives radiant heat and transfers the radiant heat to a heat receiving medium liquid, and particularly relates to the surface structure of a heat receiving plate of a flowing-down type heat collector. .

ている。(Prior Art) A technique is well known in which a heat-receiving plate is provided with a gutter or ridge-like protrusions, and these uneven surfaces are used to cause water to flow down. For example, there is a method in which fine rod-like bodies are provided in parallel at intervals along the top and bottom along the heat receiving plate, and water is caused to flow down along the rod-like bodies. Alternatively, a method has been used in which the heat receiving plate itself is mechanically deformed to form a wave-shaped gutter, or fine ridge-like unevenness is formed, and the uneven surface is used as a water guide path.

ストダウンに余り期待できない難点がある。(Problems to be solved by the invention) What is common to these series of conventional technologies is that none of them are suitable for mass-produced structures, and that the heat loss is large, so improvements are costly. It is said that it is difficult to increase heat collection efficiency to an extent commensurate with the increase. In general, flowing-down type heat collectors are well suited to current construction, and have the advantage of being cheap in terms of performance (in the case of low-temperature heat collection), but they are not suitable for mass production and are not effective in reducing costs due to mass production. There are some unexpected drawbacks.

In this example, the materials 1d are inclined toward one side of the heat collector and are arranged vertically in parallel. The heat receiving medium liquid is supplied to the highest position of the material, and flows down the material to the lowest position of the material. In the illustrated example, the material 1d has a superelevation slope, but if the heat collector is of a horizontally elongated type, the material 1d is distributed from the center of the heat collector to the left and right, and the heat transfer liquid supplied to the center of the material is directed in both directions. It is also possible to configure the process downstream.

The flowing liquid will no longer converge or meander irregularly,
It flows down while maintaining a relatively uniform spread. This regulating effect in the downstream direction is not greatly influenced by the ring shape of the heat receiving plate or the length of the heat receiving plate.
