Abstract

The invention provides a phase change type radiator. The phase change type radiator comprises an inlet and outlet pipeline (1), a fluid pipeline (2) and a honeycomb plate (3). The fluid pipeline (2) is provided with a phase change structure; the fluid pipeline (2) is bent into a U-shaped structure; the inlet and outlet pipeline (1) is connected with the fluid pipeline (2); and the fluid pipeline (2) is buried in the honeycomb plate (3). The invention provides the phase change type radiator which is composed of the fluid pipeline with a phase change structure, a honeycomb plate, and the inlet and outlet pipeline, the inlet and outlet pipeline is located at the two ends of the fluid pipeline with the phase change structure, and the upper surface and the lower surface of the fluid pipeline with the phase change structure are connected with an inner surface skin of the honeycomb plate.

Description

technical field [0001] The invention relates to the technical field of spacecraft thermal control, in particular to a phase change radiator. Background technique [0002] With the development of aerospace technology, the load of the spacecraft is increasing, the power consumption is gradually increasing, and the requirements for the temperature control of the spacecraft are also getting higher and higher. The traditional cooling technology has been unable to meet the demand for large cooling capacity. The flexible heat dissipation of efficient two-phase loop technology becomes the key. The radiator used in the traditional two-phase circuit technology is to directly weld the smooth circular tube to the radiant plate or rivet it to the radiant plate in a serpentine manner. This method has many times of bending, long pipeline, large flow resistance, and radiation at the same time. The heat dissipation capability of the radiator is also restricted by the size of the radiation p...
