Abstract

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.

Description

technical field [0001] The invention relates to the technical field of aerospace thermal control, in particular to a heat dissipation structure of a phased array antenna, a phased array antenna and a satellite platform. Background technique [0002] At present, the application fields of phased array antennas used for communication functions mainly include space-borne phased array antennas and road-based phased array antennas. Due to the particularity and complexity of the spaceborne environment, the phased array antenna used on the satellite platform cannot use air cooling and water cooling to dissipate heat, but can only dissipate heat through radiation and heat conduction, and the heat dissipation methods of radiation and heat conduction cannot Provides a constant temperature cooling surface for phased array antennas. However, the existing phased array antennas used in spaceborne environments have high heat flux density and poor heat dissipation capability. Contents of ...
