The invention discloses a groove-tower combined solar-heat power generation system, which comprises a subsystem for low-temperature groove-type heat collection and low-temperature heat storage, a subsystem for high-temperature tower-type heat collection and high-temperature heat storage, as well as a power generation subsystem, wherein the subsystem for low-temperature groove-type heat collectionand low-temperature heat storage is used for receiving and gathering solar radiation energy, converting the received solar radiation energy into medium-temperature heat energy and conveying the medium-temperature heat energy to the subsystem for high-temperature tower-type heat collection and high-temperature heat storage or a low-temperature heat accumulator; the subsystem for high-temperature tower-type heat collection and high-temperature heat storage is used for receiving and gathering solar radiation energy, converting the received solar radiation energy into high-temperature heat energyand conveying the high-temperature heat energy to a power subsystem or a high-temperature heat accumulator; and the power subsystem is used for converting the received heat energy into electric energy and outputting the electric energy. The system solves the problems that a groove-type solar-heat power generation system is low in heat-collecting temperature and difficult to promote; the optical efficiency of a heliostat filed of a simple-tower solar-heat power generation system is greatly affected by the scale of power plants; and the simple-tower solar-heat power generation system is not easy to maximize. The system has the advantages of reducing initial cost and occupied area.

The invention relates to a pressure type internal concentrating collector which consists of a pressure type sealing device, a header 10, an outer glass tube 5, an inner glass tube 4, a CPC light-focusing unit 6, a heat pipe 1, a nano heat-conduction paste layer 7 and an end cover 3; the heat pipe 1 passes through the pressure type sealing device coaxially, the openings of the outer glass tube 5 and the inner glass tube 4 are jointed mutually by sealing, the CPC light-focusing unit 6 is arranged between the interlayers of the outer glass tube 5 and the inner glass tube 4, the heat pipe 1 is arranged inside the inner glass tube 4 and is coaxial with the inner glass tube 4, the nano heat-conduction paste layer 7 is filled between the outer wall of the heat pipe 1 and the inner wall of the inner glass tube 4, a cavity between the outer glass tube 5 and the inner glass tube 4 is pumped into vacuum or introduced with inert gas, the inner glass tube 4 is arranged at the focus position of theCPC light-focusing unit 6, and the end cover 3 is arranged at the mouth of the tube. The pressure type internal concentrating collector has the advantages of lower cost, higher collector temperature,stronger pressure-bearing capacity, higher reliability and the like, thus having wider adaptability in civilian use and industrial fields.
