Abstract
Over the past few decades, technological developments have faced challenges in meeting cooling needs. Further work is underway on optimal heat transfer in concentric heat exchangers; one of the double tube heat exchangers examined is the triple tube heat exchanger (TTHE). Three-pipe heat exchangers were found to be more efficient than two-pipe heat exchangers. This review presented is the working principle of the triple concentric tube heat exchanger and the proposed methodology is used in a computational fluid dynamics algorithm.

Further work is underway on optimal heat transfer in concentric heat exchangers; one of the double tube heat exchangers examined is the triple tube heat exchanger (TTHE)
The inner ring has 2 heat exchange surfaces which slightly increase the heat exchange area of the heat exchanger compared to a double tube device which increases the rate of heat exchange
Summary
The basic type of heat exchanger used in many fields of application is a double pipe heat exchanger. To cope with high temperature differences, the area of the heat exchanger must be enlarged, which would only be possible by lengthening the heat exchanger This solves this problem as the heat exchange area is increased for the same length of the double tube heat exchanger. It has three concentric tubes, three compartments called inner tube, inner ring and outer ring. The results indicated that the liquid-tosuction triple-tube heat exchanger had a much higher heat transfer and lower pressure loss than the double-tube heat exchanger. Abdelmagied M et al [2] In this paper presented are the thermo fluid characteristics of a new design of curved tube called a triple spiral tube heat exchanger (TSTHE) was achieved with a brave comparative with a double spiral tube heat exchanger (DSTHE) as particular reference. The results indicate that the most effective geometric parameter on the performance of the triple helix ground heat exchanger is the length of the helical coil, while the two parameters of the distance between centers of inner/outer helical coil branches, as well as the distance between centers of inner and outer helical coil branches, have the least effect
