The present inventors have determined that the light concentration ratio (reflector opening width/collection tube circumference length) in a concentrating vacuum tube type solar heat collector
In order to increase this, we devised an involute curve shape for the reflector. That is, as shown in FIG. 1, the concentrating vacuum tube type solar heat collector is composed of a heat collecting tube 1, a vacuum glass tube 2, a reflecting plate 3, a supporting metal fitting 4 for the reflecting plate 3, and the reflecting tube 1. The cross-sectional shape of the plate 3 is made into an involute curve. According to this configuration of the reflector, sunlight that has entered the opening width of the reflector can be substantially concentrated on the heat collecting tube by one to a plurality of reflections. In addition, the light concentration ratio can be increased without changing the direction of the heat collector in response to changes in the position of the sun over time.

Therefore, there is a problem that sunlight cannot be accurately focused on the heat collecting tube 1.

In order to reflect sunlight onto the heat collecting tube 1, silver is deposited on the shape of the reflector on the inner surface of the vacuum glass tube 2. The reflective film 3 is deposited on the inner surface of the vacuum glass tube 2 and brought into close contact with the inner surface of the vacuum glass tube 2, so that it will not be deformed by vibrations during transportation or the like.

A reflector 5 made of the same glass as the vacuum glass tube 2 is inserted into the shape of the reflector inside the cylindrical vacuum glass tube 2, which has been processed into an involute curve shape and has a reflective film made of vapor-deposited silver. Weld the ends. Since the inner surface of the vacuum glass tube 2 and the reflector 5 are welded together, they will not be deformed by vibration.
