Payload cooling device for satellite ground

Abstract

The invention discloses a satellite ground payload radiator mainly comprising an air-cooled main machine, corrugated pipes, junction stations, a junction station bracket and end ducts. Multiple outlets of the air-cooled main machine are communicated with inlet ends of the multiple junction stations through the corrugated pipes respectively; the lower part of each junction station is supported by the junction station bracket and the outlet ends of the junction stations are communicated with the end ducts correspondingly; each end duct is connected to a payload device in the closed capsule of a satellite through a connection pipe to radiate heat for the payload device; the air-cooled main machine is provided with the multiple high-power outlets, one ends of the junction stations are connected with multiple end hoses, and the other ends of the junction stations are connected with the corrugated pipes correspondingly, and the end ducts are made of elastic plastic. Compared with the prior art, the satellite ground payload radiator has the advantages that the noise is small, wind with a certain speed can be directly sent to the surface of the device, the radiating effect is guaranteed, and the execution efficiency is high; the satellite ground payload radiator is suitable for the operation condition of any closed capsule, and can be modified according to the actual number of devices, and the application scope is broad; reliability is high, and the service life is long.

Description

technical field [0001] The invention belongs to the technical field of spacecraft payload heat dissipation, and specifically relates to a device for all-weather and full-process heat dissipation for satellite payload equipment installed. Background technique [0002] The heat consumption of a certain satellite communication cabin (such as a closed cabin) is as high as 4400W. During the test of the single cabin of the communication cabin and the whole satellite state, the heat dissipation of the payload equipment in the communication cabin directly determines the operating temperature of the payload equipment. The traditional method currently used is to use an axial flow fan or an electric fan to supply air and heat dissipation to the target payload equipment, but this method is due to the scattered and non-concentrated wind force, and the shielding of some cables and other components in the process makes it difficult to transmit air to the payload equipment. The wind speed o...

The traditional method currently used is to use an axial flow fan or an electric fan to supply air and heat dissipation to the target payload equipment, but this method is due to the scattered and non-concentrated wind force, and the shielding of some cables and other components in the process makes it difficult to transmit air to the payload equipment. The wind speed on the surface is low and cannot effectively dissipate heat
