Heat pipe heat exchangers (HPHEXs) are widely used in various industries. In this paper, a novel model of liquid–liquid exchanger countercurrent manner is established by considering the evaporation and condensation thermal resistances inside pipes (HPs). The discrete method added to HPHEX determine HPs temperature change trend transfer fluid HPHEX. verified structure experimental data existing ...

Heat exchangers are one of the most important devices of mechanical systems in modernsociety. Most industrial processes involve the transfer of heat and more often they requirethe heat transfer process to be controlled. A heat exchanger is the heat exchanged betweentwo media, one being cold and the other being hot. There are different types of heatexchanger, but the type which is widely used in...

Heat exchangers are the critical components of refrigeration and liquefaction processes. Selection of appropriate operational conditions for cryogenic recuperative heat exchanger and expansion valve operating in Joule-Thomson cooling system results in improving the performance and efficiency. In the current study, a straightforward procedure is introduced to design an efficient Joule-Thomson co...

This paper deals with the performance of a heat pipe solar collector. The solar collector consisted of an interconnected heat pipe so as to reduce the production cost by using an interconnected heat pipe because all the heat pipes can be evacuated, sealed and tested at once. Performance of a prototype of the heat pipe solar collector was experimentally examined, and the results were compared wi...

An analysis of the end use energy in EU reveals that industry is one three dominant categories, which accounts for 26.1% final energy. In case aluminium industry, approximately 70% consumption due to heat and thermal processes, highlighting a vast potential waste recovery technologies. Within die casting liquid cast, formed, cooled, further processed within process, includes sub-processes: solu...

The single-phase flow and thermal performance of a double pipe heat exchanger are examined by experimental methods. The working fluid is water at atmospheric pressure. Temperature measurements at the inlet and outlet of the two streams and also at an intermediate point half way between the inlet and outlet is made, using copper-constantan thermocouple wires. Mass flow rates for each stream are ...
