In order to deeply understand and develop the anti-icing technology of heat pipe,the research status of different types of heat pipes in aircraft anti-icing field was mainly discussed,the theoretical and experimental results of loop heat pipe,rotating heat pipe and gravity heat pipe used in anti-icing of aircraft wings and engine front parts were summarized,the main characteristics of loop heat pipe and rotating heat pipe for anti-icing were sorted out,and the development direction of heat pipe anti-icing technology was prospected.The results showed that the researches on heat pipe anti-icing technology were still at initial stage,and most of them stayed in the design and feasibility verification of heat pipe anti-icing system.These suggested that subsequent research should be concentrated on experiments,and the method of combining numerical calculation and experimental research should be adopted,with a focus on the operation characteristics of heat pipe anti-icing system under the aircraft environment and icing meteorological conditions;moreover,the influences of factors such as the characteristics of the working medium,working temperature and liquid filling rate on the heat transfer performance of the heat pipe anti-icing system were determined,thus providing a theoretical and experimental support for the design optimization and practical application of heat pipe anti-icing system.
