Problems solved by technology

However, this design is not integrated with the antenna structure, and can only be screwed to the heat source, which not only weighs a lot, but also increases the contact thermal resistance. At the same time, its lattice structure is a traditional cylindrical structure, and the heat transfer area is small, which limits its Further shortening of phase transition time

Abstract

The invention relates to a lightweight thermal control support structure of a space-borne antenna and the space-borne antenna. The support structure comprises a bearing heat dissipation plate with twosides which are used for being connected with an antenna unit and a TR module. The bearing heat dissipation plate has a hollow structure with a lattice structure inside. The hollow structure is divided into a phase change material filling lattice region and an outer lattice region. The phase change material filling lattice region is corresponding to the TR module. The phase change device and theantenna array panel are integrated into one body and arranged as the bearing heat dissipation plate so that the phase change heat dissipation can be realized while realizing the weight reduction design, the structure is compact and good support and heat dissipation effect for the antenna unit and the TR module can be realized.

Description

technical field [0001] The invention relates to an antenna support structure, in particular to a lightweight thermal control support structure of a space-borne antenna and the space-borne antenna. Background technique [0002] The array panel of the spaceborne phased array antenna not only needs to provide installation support and heat dissipation path for the antenna unit, but also ensure that the temperature uniformity among the units and the thermal deformation of the real panel do not exceed the design requirements. The antenna array panel is usually designed as an aluminum honeycomb sandwich structure to reduce weight while ensuring the rigidity of the antenna. Since the start-up time of the antenna is short when it is working in orbit, phase change materials are often used for auxiliary thermal control. The traditional design usually requires the design of a separate phase change module, and machine ribs are often used to increase the contact area of ​​the phase chang...
