The invention relates to a
heat pipe type
solar energy ORC (organic Rankine cyle) low-temperature thermal power generating
system which comprises an ORC power generating
system, a heat storage
system and a
heat pipe collector system. The power generating system comprises working medium
evaporation sleeves, a
turbine, a power generator, a heat regenerator, a condenser and the like. The
heat pipe collector system is composed of more than three heat
pipe collector modules; each module includes a heat
pipe, a vacuum
pipe and a CPC (composite parabolic) reflector; the condensing section of the heat pipe is embedded in the working medium
evaporation sleeves, and the evaporating section of the heat pipe is arranged at the bottom part in the CPC reflector; and the more than three working medium
evaporation sleeves are connected in series. In the invention, the heat pipe, the CPC reflector and an ORC are combined to form the heat pipe type
solar energy low-temperature thermal power generating system based on the ORC. Compared with the traditional
solar energy low-temperature thermal power generating system, the invention not only has
high heat efficiency and strong pressure
bearing capacity, but also innovatively utilizes the
phase inversion heat exchanging principle of the heat pipe to reduce a heat conduction oil loop and realizes the high-efficiency heat exchanging between an organic working medium and the heat collector.
