  • Patent number: 4261337
    Abstract: The solar heat collector includes an enclosure having a solar energy transmitting cover member and a solar energy absorbing base member. Within the enclosure, structure is provided, connected to a fluid inlet, for causing a stream or film of fluid to flow along the interior surface of the cover member. The same structure may be used to impart a separate flow of fluid along the energy absorbing base member. The cover member is oriented to prevent the gravitational forces on the fluid stream, flowing along the interior surface of the cover member, from overcoming the adhesion forces between the stream and the interior surface of the cover member. This stream removes condensation from the cover member as it captures heat therefrom. The stream may be created by spraying fluid on the interior surface of the cover member or by a fluid dispensing member having a fluid outlet adjacent the interior surface of the cover.
