Research ArticleOpen accessEvery word in the titleComparisons of Heat Transfer Performance of a Closed-looped Oscillating Heat Pipe and Closed-looped Oscillating Heat Pipe with Check Valves Heat ExchangersP. Meena, S. RittidechThis research was to study the comparisons of heat transfer performance of closed-looped oscillating heat pipe and closed-looped oscillating heat pipe with check valves heat exchangers with R134a, Ethanol and water were used as the working fluids. A set of heat pipe heat exchanger (CLOHP and CLOHP/CV) were made of copper tubes in combination of following dimension: 2.03 mm inside … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2008 · 7,492 accessesView PDF Cite

Research ArticleOpen accessEvery word 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 accessIn the keywordsMathematical Model of the Optimum Heat Pipe Heat Exchanger for a Condenser of Vapor-Compression Refrigeration CycleP. Yeunyongkul, P. Sakulchangsatjatai, P. TerdtoonProblem statement: This study theoretically investigated applying heat pipe as a heat exchanger in the condenser of vapor compression refrigeration system for sustainable well-being. Split-type air conditioner for residential propose was considered. To reduce pressure drop and recover heat from the condensing process of the refrigeration cycle, this investigation tried to use Closed Loop Oscillating Heat Pipe (CLOHP) instead of … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 8,631 accessesView PDF Cite
