SIMPLIFIED ANALYTICAL MODEL OF VERTICAL ARTERIAL HEAT PIPES
In the paper engineering design is given for vertical arterial heat pipes. Such heat transfer devices are of interest since in them liquid is transferred from the condenser to the evaporator through the artery rather than through the film flowing down the wall where suction and distribution of the liquid over the condenser and evaporator
walls are performed through triangular grooves. This design provides a higher effective thermal conductivity at high heat fluxes compared to the thermosyphon design
Expressions for a limit heat flux transferred by heat pipes are presented as a function of the groove geometry, groove width and pore dimensions. Heat pipe performances are considered for various ratios of these parameters.
