NOVELTY - Large-size photovoltaic receiver of a tower-type solar power station (100) with application of an array of heliostats (101) for concentration of solar radiation on the large-size photovoltaic receiver, is claimed. The large-size photovoltaic receiver is designed as a heat sink unit with photovoltaic cells (106) mounted on outer side of the heat sink unit, where the heat sink unit comprises an evaporator chamber (103) and a condenser (104) in fluid communication with evaporation chamber, condenser is positioned at somewhat higher level regarding the evaporation chamber.    USE - The large-size photovoltaic receiver of a tower-type solar power station is useful in heat sink system.    ADVANTAGE - The large-size photovoltaic receiver of tower-type solar power station: minimizes energy requirements for circulating coolant; and efficiently and economically generates electrical power.    DETAILED DESCRIPTION - Large-size photovoltaic receiver of a tower-type solar power station (100) with application of an array of heliostats (101) for concentration of solar radiation on the large-size photovoltaic receiver is claimed. The large-size photovoltaic receiver is designed as a heat sink unit with photovoltaic cells (106) mounted on outer side of the heat sink unit, where the heat sink unit comprises an evaporator chamber (103) and a condenser (104) in fluid communication with the evaporation chamber, the condenser is positioned at somewhat higher level regarding the evaporation chamber, the evaporation chamber comprises a large-size metal plate with photovoltaic cells installed on its external surface, internal surface of this metal plate is provided with a capillary structure with open porosity, a distributing means installed on the upper section of the internal side of the large-size metal plate, the evaporation chamber includes lateral walls and a rear wall in addition with an outlet connection for removal of vapors of the working medium and at least one inlet connection for supply of the liquid working medium into the distributing means, and an array of spacers installed on the internal side of the rear wall, the condenser is designed as a heat exchanger of the recuperative type and is provided with inlet and outlet connections which are in fluid communication with outlet and inlet connections of the evaporation chamber, a vacuum pump and a cooler-separator which are in fluid communication with the condenser and the evaporation chamber and, the vacuum pump and cooler-separator serve for periodical removal of non-condensable gases from the interiors of the condenser and the evaporation chamber, a pressure gauge that measures internal pressure in the evaporation chamber, a cooler for cooling and condensation of the working medium vapors in the condenser, the vacuum pump and the cooler ensure such pressure of the working medium in the evaporation chamber and the condenser which is lower than the atmospheric pressure, and a control block that regulates the rate of cooling the working medium vapors in the condenser.    DESCRIPTION OF DRAWING(S) - The figure shows a general view of the solar power station with photovoltaic cells installed on the tower and the array of heliostats, which concentrate solar radiation on the photovoltaic cells.
