【 摘 要 】

Among the various technologies available today heat pipes can be considered as an efficient heat transfer device. A heat pipe is a device which can transfer heat though long distances. Heat pipes (HPs) have gained importance in recent years, mainly in the field of cooling electronic components, since they need heat removal from limited volumes to the environment. Small HPs are widely used in electronic applications, which are normally limited by the compact structure and dimensions of the electronic device. Among small heat pipes, loop heat pipes (LHPs) are usually preferred due to high efficiency and compact size. Nano fluids also have attracted attention due to their superior heat transfer properties in recent years. The lower thermal conductivity of conventional working fluids puts a limit on heat transfer. The thermal performance of heat pipes may be improved by using nano fluids as working fluids. This review presents an investigation on the design, operating principle, advantages and applications of loop heat pipes. Furthermore, emphasis is given on the effect of the nano fluid in the thermal performance of LHPs.
