Research ArticleOpen accessPhrase in the titleEffect of Inclination Angle on Performance Limit of a Closed-End Oscillating Heat PipeT. Hudakorn, P. Terdtoon, P. SakulchangsatjataiThis study presents the effect of inclination angle on the performance limit of a Closed-End Oscillating Heat Pipe (CEOHP). The study was divided into 2 corresponding parts. The first part was visual study. The CEOHP was made of Pyrex glass tube with the inner diameter of 1.0 mm, evaporator length of 50 mm and had 10 meandering turns. The lengths … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2008 · 7,516 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleEffect of Internal Flow Patterns on Heat transfer Performance of a Closed-end Oscillating Heat Pipe at Vertical PositionS. Rittidech, L. Yodluk, K. SongsornThis article describes the effects of varying bond numbers (Bo) and aspect ratios (Le/d) on flow pattern of a close-end oscillating heat-pipe (CEOHP). The CEOHPs used employed a glass tube with inside diameter of 3 mm. The length of evaporator of 100 and 150 mm (the lengths of evaporator adiabatic and condenser section were equal) were employed with 10 turns. … …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 7,062 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleEffect of Geometry and Dimensionless Parameters on Heat Transfer Characteristics of a Closed–end Oscillating Heat-pipe at Vertical PositionS. Rittidech, K. PhalasinThis heat transfer characteristics of a closed-end oscillating heat-pipe (CEOHP) depend on a number of parameters. They are the number of turns, inner diameter of the tube, aspect ratio and the dimensionless parameters of heat transfer. The CEOHPs used to employ a copper tube with inner diameter of 0.66, 1.09 and 2.03 mm. The lengths of the evaporator, adiabatic and … …American Journal of Applied Sciences, Vol. 2, Issue 11 · 30 Nov 2005 · 6,642 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleCPU Cooling of Desktop PC by Closed-end Oscillating Heat-pipe (CEOHP)S. Rittidech, A. Boonyaem, P. TipnetThe CEOHP cooling module consisted of two main parts, i.e., the aluminum housing and the CEOHP. The house casing was designed to be suitable for CEOHP. The housing to drilling for insert the CEOHP. The CEOHP design employed copper tubes: Two sets of capillary tubes with an inner diameter of 0.002 m, an evaporator length of 0.05 and a condenser … …American Journal of Applied Sciences, Vol. 2, Issue 12 · 31 Dec 2005 · 8,454 accessesView PDF Cite
