Abstract
Flat heat pipe,due to its advantages of high heat transfer efficiency,great temperature uniformity,and safety and reliability,has become one of the important options for spacecraft thermal control.Optimization of wick structure is an important method to improve the flow and heat transfer performance of flat heat pipe.For the design of wick structures,the method of designing high performance wick structures was revealed,and guidance was provided for the selection and application of macro-meso-micro multiscale numerical model.For wick surface modification,the importance to improve nanostructure mechanical stability,adjust heat transfer mechanism and carry out numerical simulation research was emphasized.To solve the problems of heat dissipation and high radiation in space environment,the development directions of flat heat pipe in spacecraft thermal control were figured out,and the shortcomings of current research were analyzed.
