Solar heating device for use as thermo-solar device for heating liquid, has concentrator changed from spherical shape into parabolic shape, where absorber medium exhibits sectional and/or contact points with caustic curve of concentrator
The device (100) has a concentrator (10) i.e. groove or trough-shaped mirror, changed from a spherical shape into a slightly parabolic shape. An absorber medium is located within a caustic curve of the concentrator. The absorber medium exhibits a sectional point and/or a contact point with the caustic curve of the concentrator. The absorber medium flows through a liquid tube (20) and heated by concentration of incident light by the concentrator. The tube is attached to a glass plate, acryl glass plate or Plexiglas(RTM: light, transparent, weather-resistant thermoplastic) plate. An independent claim is also included for a solar heating method for heating an absorber medium.
