The water-cooled heat exchanger is one of the key components in a pulse tube refrigerator. Its heat exchange effectiveness directly influences the cooling performance of the refrigerator. However, effective heat exchange does not always result in a good performance, because excessively reinforced heat exchange can lead to additional flow loss. In this paper, seven different water-cooled heat ex...

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 (STHEs) is done by sophisticated computer software. However, a good understanding of the underlying principles of exchanger design is needed to use this software effectively. This article explains the basics of exchanger thermal design, covering such topics as: STHE components; classification of STHEs according to construction and according to service; data needed for thermal de...

Heat EXchangers (HEX) that are used in City Gate Station (CGS) systems are modeled numerically to recover the exhaust waste heat. It was tried to find the best viscous model to obtain results in accordance with experimental results and to change the heat exchanger design. This HEX is used for recovering heat from exhaust flue gas with a mixture of 40% water and 60% ethylene glycol as the coolin...

This study investigates the heat transfer performance of a novel ZA27 metal foam exchanger. An open-celled is combined with thin-walled copper tube in single-step casting process. The between two separated water streams flowing through and foam, respectively, measured compared to an equivalent shell exchanger arrangement. Heat enhancement up 71% rate exceeding 30 kW are observed attributed incr...

This study focuses on the various experimental research analyses on performance of tubular heat exchangers the tubular heat exchanger is used throughout various industries because of its inexpensive cost and handiness when it comes to maintenance. In this paper we discus about tubular heat exchanger there are several thermal design factors that are to be taken into account when designing the tu...

An existing commercial scale low temperature R-502 refrigeration plant has been extensively instrumented for evaluating R-502 long term replacements R-404A, R-407A and R-507. This installation is part of the refrigeration plant located at the Thermal Technology Centre. The R-502 retrofit test facility has an internally compounded two stage 40 HP reciprocating compressor equipped with desuperhea...

Considering lifecycle cost analysis during the design phase of thermal systems gives the design effort more worth. Furthermore thermodynamic exergetic optimization is a proven useful method for determining the most lifecycle cost optimal design of thermal systems for given thermodynamic constraints. The most thermodynamic efficient heat exchanger design basing on first law analysis may not be t...
