Abstract

The invention relates to a supporting structure of a satellite solar cell square matrix circuit and aims at providing an implementation method for solar cell array substrates of large grid panels and solving the problems of large weight of a solar cell array substrate structure, poor heat dissipation capacity of the back surface of a cell, poor environmental adaptation and the like in the prior art. The method is characterized in that the large grid panels [1] and [5] are made of an M60J-3K high-modulus carbon fiber / epoxy 648 resin material and are woven in [0 / 90]2 direction; the widths of narrow bands in the warp direction and the weft direction are 1.2-1.5mm, the space is 6mm*6mm, and the thickness is 0.30mm; used adhesive films [2] and [4] are Redux312UL adhesive films, and the amount of used adhesive is controlled to be between 40g / m<2> and 50g / m<2>; and a used honeycomb core [3] is an HEXCEL CRIII-3 / 8-5056-0.0007p-1.0 regularly hexagonal hollow durable aluminum honeycomb core. By adopting the method, the problems of large weight of the solar cell array substrate structure, poor heat dissipation capacity of the back surface of the cell, poor environmental adaptation and the like in the prior art are solved; and the method has the advantages of light weight of the substrate structure, high heat dissipation capacity of the back surface of the cell, high capacity of resisting spatial environment temperature and temperature alternation and the like.

Description

technical field [0001] The invention relates to a supporting structure of a satellite solar cell square array circuit, in particular to a solar cell array substrate of a large grid panel. Background technique [0002] The solar cell array substrate provides good safety support and support for the solar cell array circuit; the structure of the solar array remains intact under the impact of high-energy particles such as vacuum in orbit, high and low temperature alternating, and ultraviolet protons; under the connection and locking of the deployment mechanism, The vibration characteristics such as the natural frequency of the deployed solar cell array meet the technical requirements. [0003] At present, solar cell array substrates generally use 4mm×4mm grid panels, and seldom use 4mm×6mm grid panels, resulting in large substrate structure, weak heat dissipation capacity, and poor adaptability to the environment. [0004] Do not find description or report similar to the presen...
