A gravity heat pipe for high voltage vacuum interrupter

Journal of Zhejiang University-SCIENCE A, 2009
To enhance nominal current of high voltage vacuum circuit breakers (VCBs), a gravity heat pipe was proposed to replace stationary conducting rod of a high voltage vacuum interrupter. The heat pipe is composed of two coaxis tubes: the external tube is made of oxygen-free copper and the inner tube is made of stainless steel.

Design, implementation, and characterization of a gravity heat pipe

2017
Les caloducs gravitaires (CG) sont des thermosiphons fermés à deux phases. On les appelle aussi caloducs sans mèche assistés par gravité. Ils sont construits en vidant un tube fermé et en l'emplissant ensuite avec la quantité appropriée d'un fluide choisi.

The Anti-Gravity Phenomena in EHD Heat Pipe Model

Heat Transfer, Volume 4, 2002
A heat pipe model of electrohydrodynamical (EHD) enhancement heat transfer has been designed and made. The insulating liquid was selected as working fluid and the copper wire whose diameter was 1mm was used as the high voltage electrode. The temperature in the inlet and outlet of both the vaporization section and the condensation section, the ...

Mathematical model of heat transport through gravity assisted heat pipe in order to set length of the pipe

AIP Conference Proceedings, 2014
Mathematical model of heat transport is based on formation of condensate film in the condenser of the heat pipe and evaporation from in the evaporation section. The model is built on the Nusselt analysis and is complemented by empirical correlations that have been published in the past.

Effect of Gravity on the Thermal Instability of a Closed Loop Pulsating Heat Pipe

2013
A multi-turn Closed Loop Pulsating Heat Pipe (CLPHP) made of copper (I.D. 1.1mm, O.D. 2mm), filled with FC-72 is experimentally investigated. The study focuses in particular on the combined effect of the inclination angle (gravity) and heat input level on the device stability and thermal performance.

The gravity assisted heat pipe with application to concrete shell steam condensers

Journal of Heat Recovery Systems, 1986
Abstract The manner of heat transfer in conventional steam condensers has been altered so that the cooling water and steam are separated by a concrete wall. The gravity assisted heat pipes which pass through the concrete membrane are used in transferring the heat between steam and water.
