The Impact Factors on Heat Transfer Performance of Micro Heat Pipe

The micro heat pipes have a wide concern and attention,such as theory and various practice engineering fields,due to their excellent heat transfer performance. The wick is a key factor to affect the heat transfer performance in working cycle of micro heat pipe. The wick not only could promote the working fluid circulation flow,but also phase change,improving the heat transfer coefficient of micro heat pipe. The paper is overviewed the concept,type and performance of micro heat pipe and reviewed the research history. The micro heat pipe research status mainly include two sides as the whole section and the phase changing section( evaporation section and condenser section) of heat pipe in heat transfer. Finally,the micro heat pipe research ideas have been analyzed and its possible future research directions prospected.
