The invention belongs to the technical field of aerospace thermal control and relates to a heat dissipation structure of a phased-array antenna, a phased-array antenna and a satellite platform. The heat dissipation structure of the phased-array antenna is used for conducting heat dissipation on the phased-array antenna of a satellite platform, wherein the satellite platform comprises a satellite cabin plate. The heat dissipation structure of the phased-array antenna comprises a first heat pipe, a flat heat pipe and a second heat pipe; the first heat pipe is buried in the satellite cabin plate; the flat heat pipe is arranged on the inner surface of the satellite cabin plate and used for supporting an antenna assembly of the phased-array antenna; a first protrusion is arranged on the flat heat pipe; the first protrusion is located in the satellite cabin plate, and the outer side face of the first protrusion and a part of the flat heat pipe located on the outer side of the first protrusion are attached to the first heat pipe; and the second heat pipe is arranged on the inner surface of the satellite cabin plate. The heat dissipation structure of the phased-array antenna is small in occupied space; the heat dissipation problem of the antenna assembly is solved; the heat dissipation path is shortened; the heat dissipation efficiency is improved; and normal work of the phased-array antenna on the satellite platform is guaranteed.
