PURPOSE: A solar heat collecting device is provided to improve the efficiency of collecting heat as sunlight is evenly collected into the recessed groove of a reflection unit regardless of the position of the sun. CONSTITUTION: A solar heat collecting device comprises a tube-shaped absorbing unit(110), a reflection unit(120), and a case(130). The tube-shaped absorbing unit collects sunlight, and heat medium flows in the tube-shaped absorbing unit. The reflection unit comprises an opening and a recessed groove. The sunlight is incident to the opening. The recessed groove is separately placed from the tube-shaped absorbing unit at a constant distance so that the incident sunlight is collected in the tube-shaped absorbing unit. One surface of the case is formed with a transmitting body(133), and the sunlight penetrates the case. The case accommodates the tube-shaped absorbing unit and reflection unit. |
