Description

technical field [0001] The invention relates to a two-phase fluid circuit condenser device for spacecraft, belonging to the field of aerospace thermal control. Background technique [0002] With the continuous development of aerospace remote sensing technology, optical remote sensors have higher and higher temperature requirements for their core components (such as CCD components or CMOS components), and it is necessary to use two-phase fluid circuit technology for thermal control design. The system composition of the two-phase fluid circuit is as follows: figure 1 shown. It includes a driving device 11, an evaporator 12, a condenser 14, a radiator 15, a connecting pipeline 13, and the like. When the aerospace remote sensor is used in orbit, it is necessary to dissipate the heat generated by the two-phase fluid circuit to the space within a certain temperature range and achieve thermal balance. In the two-phase fluid circuit system, in order to realize heat dissipation, t...

Problems solved by technology

However, the structure of the remote sensor is usually a non-planar structure, and the body-mounted radiator for this structure is not easy to process

In addition, in order to realize the processing and development of super-large structures, most of the camera structures adopt aluminum honeycomb structures with high strength, good rigidity and light weight. The contact thermal resistance between the pipeline and the honeycomb structure is relatively large
