Title: Solar heat collecting device
Inventor: FUKUTAKE HEIJI
IPC: F24S23/74
Filed: 2000-02-10
Abstract: PROBLEM TO BE SOLVED: To provide a solar heat collecting device which can raise the temperature of a fluid by efficiently absorbing heat from sunlight with a simple structure. SOLUTION: This heat collecting device has a tubular solar heat collecting body which raises the temperature of the fluid by converting sunlight into heat upon receiving the sunlight and a reflecting plate which is opened toward the sun and surrounds the collecting body so as to reflect the sunlight toward the collecting body. The body is constituted in such a double-pipe structure that is composed of an inner pipe and an outer pipe and has a fluid passage having an annular cross section between the pipes. Since the ratio of the quantity of the fluid which comes into contact with the outer periphery of the inner pipe to the flow rate of the fluid increases and only the high-temperature fluid near the outer periphery can be utilized, the device can raise the temperature of the fluid by efficiently absorbing heat from the sunlight.  When a special shaped pipe which is formed by partially or entirely deforming a circular pipe is used as the tubular solar heat collecting body, the ratio of the quantity of the fluid which comes into contact with the pipe to the flow rate of the fluid increases as compared with the case where the circular pipe is merely used and the device can raise the temperature of the fluid by efficiently absorbing heat from the sunlight similarly to the case where the double-pipe structure is used.
