Solar photo-thermal receiving device

Abstract

A solar photo-thermal receiving device, consisting of a sealed structure (1) and a solar photo-thermal receiver (2) inside the sealed structure (1); the solar photo-thermal receiver (2) includes a secondary absorption heat-exchange pipe (17) and a primary absorption heat-exchange pipe (16); the temperature of a heat exchange medium inside the secondary absorption heat-exchange pipe (17) is lower than that of a heat exchange medium inside the primary absorption heat-exchange pipe (16); the secondary absorption heat-exchange pipe (17) receives the heat energy released by the primary absorption heat-exchange pipe (16) and/or receives the solar heat not received by the primary absorption heat-exchange pipe (16); the solar photo-thermal receiving device takes the heat away via the heat-exchange medium flowing inside the pipes of the solar photo-thermal receiver (2). The solar photo-thermal receiving device can be applied in a through type, a Fresnel array and a tower type solar photo-thermal concentration system.
