A novel flat heat pipe and its thermal performance analysis

摘要

The paper presents a novel flat heat pipe that has the characteristics of easy to construct, can withstand a higher pressure when vacuumed and can be constructed into various scales. The thermal performance of the novel flat heat pipe with or without the wick was analysed using an analytical model. The analysis related to the relations of the maximum heat transport capacity with liquid fill level, working temperature and heat pipe geometry dimension for different working fluids.
