The invention relates to the technical field of
thermal control of electronic components, in particular to a self-energy-storage
thermal control system and method of
satellite-borne communication equipment. The
system comprises a shell, a plurality of PCBs, a plurality of
phase change energy storage cold plates and a liquid cooling pipeline, the PCBs, the
phase change energy storage cold plates and the liquid cooling pipeline are all arranged in the shell, a first liquid flow channel is arranged in a shell body of the shell, a
phase change energy storage material is arranged in a first inner cavity in each phase change energy storage
cold plate, a second liquid flow channel is arranged in a second inner cavity in each phase change energy storage
cold plate, and the first liquid flow channel is communicated with the second liquid flow channel. The first inner cavity is attached to the PCB, the second inner cavity is opposite to the first inner cavity, the liquid cooling pipeline is connected with the first liquid flow channel and the second liquid flow channel, and liquid cooling working media circulate in the second liquid flow channel, the liquid cooling pipeline and the first liquid flow channel. And the liquid cooling working medium is used for circulating the heat of the phase change energy
storage material absorbing the heat of the PCB into the shell and dissipating the heat to the external environment. According to the technical scheme, the problem that on-
orbit short-term startup temperature rise of the
satellite-borne communication equipment is too large can be solved, heat can be used for low-temperature heat preservation of the equipment, and
temperature control power consumption of the whole
satellite is saved.
