Heat Transfer Effectiveness of Heat Pipes
Journal of Heat Recovery Systems, 1982Abstract Heat transfer effectiveness (recovery factor), HTE, of one heat pipe, HP, is defined as the function of two dimensionless groups of NTU type (number of transfer units) from the] evaporator and the condenser. In the case of the HP heat exchanger it is demonstrated that the HTE is a function made up of only three elements, viz; the HTE of the ...

Physics in Technology, 1973
The heat pipe is a device having a high thermal conductance which utilizes the transport of a vapour and rejection of latent heat to achieve efficient thermal energy transport. The theory of heat pipes is well developed. Their use in applications involving temperatures in the cryogenic regime, and with development units running as high as 2000 degrees ...

Entrainment limits in heat pipes
3rd International Heat Pipe Conference, 1978The present work explores the physical basis for the entrainment limit in heat pipes and attempts to develop adequate quantitative criteria for the limit. Analogy is emphasized here between the entrainment phenomenon in heat pipes and the flooding phenomenon in countercurrent vapor-liquid flow systems.

Naval Engineers Journal, 1967
The principle of the heat pipe is an amazingly simple one. Phenomena involved are surface tension and latent heat of the working fluid. There are no parts that move. Its effective thermal conductivity is hundreds of times more than solid conductors like copper and silver.

Is a non-phase change heat pipe a new heat pipe?
International Journal of Heat and Mass Transfer, 2019Abstract A Non-phase change heat pipe (NPCHP) with no wick was proposed recently as a new heat pipe which is not dependent on a wick or phase change at steady state operation and where heat transfer is driven by the pressure response to a heat input, rather than phase change.

Heat Transfer Characterizations of Heat Pipe in Comparison With Copper Pipe
Journal of Heat Transfer, 2009The article presents some significant experimental data for studying the heat transfer behavior of heat pipe, which will further help the cooling efficiency improvement of the heat pipe cooler. It is well known that the heat pipe owns the extreme large heat conductivity and is often integrated with cooling plates for CPU cooling.
