The invention discloses a middle temperature heat pipe type receiver for tower solar thermal power generation. The receiver consists of a heat pipe (1), a light inlet hole (2) and a shell (3); a middle temperature fluid used as a circulating working medium is in the heat pipe; the light inlet hole is an interface for receiving solar energy; the shell is hexahedron-shaped and wholly adopts a frame beam structure; the heat pipe is divided into an evaporation section (1-1) and a condensation section (1-2), and a contact block is welded in the middle of the heat pipe; the evaporation section is arranged at the lower part and is positioned inside the shell; the condensation section is positioned at the upper part and is positioned outside the shell; a jacket pipe (4) is adopted outside the condensation section, inlet and outlet pipes are arranged at the top and the bottom of the jacket pipe and are connected with upper and lower headers (6) and (7) through interface flanges (10); high-temperature heat conductive oil used as a heat-transfer fluid is in the jacket pipe. Compared with a traditional tower receiver, the receiver has the benefits that the receiver adopts a heat pipe type, and can be used on the middle temperature section at 250-400 DEG C, the system reliability is ensured, and the efficiency is improved.
