“…Yang et al (2015) experimentally proved that the high (dP/dT) sat of methanol contributes to the fluid oscillating and improved the thermal performance of the MOHPs. In addition, increasing number of researches concentrated on optimizing the structural design to improve the MOHPs' thermal performance (Chen et al, 2021). Sun et al (2018) pointed out that micro-cavities embedded on the micro-channel wall can promote nucleation, thus enhancing the thermal performance of MOHPs.…”

“…The thermal resistance and temperature difference increase with the increase in the dimensionless thermal difference. Chen et al [158] tested the heat transfer performance of series two-channel plate PHP under uneven heating and the experimental equipment which was shown in Figure 17. The heating of uneven PHP has better heat transfer performance at low heating power.…”

The application of batteries has become more and more extensive, and the heat dissipation problem cannot be ignored. Oscillating Heat Pipe (OHP) is a good means of heat dissipation. In this paper, the methods to improve the energy conversion and flow thermal performance of micro-channel OHP are studied and summarized. The working principle, heat transfer mechanism, advantages and applications of PHP are also introduced in detail in this study. Proper adjustment of the micro-channel layout can increase the heat transfer limit of PHP by 44%. The thermal resistance of two-diameter channel PHP is 45% lower than that of conventional PHP. The thermal resistance of PHP under uneven heating can be reduced to 50% of the original. PHP pulse heating can alleviate the phenomenon of dryness. Different working fluids have different effects on PHP. The use of graphene nano-fluids as the work medium can reduce the thermal resistance of PHP by 83.6%. The work medium obtained by the mixture of different fluids has the potential to compensate for the defects while inheriting the advantages of a single fluid.

“…The overall thermal conductivity was increased by 5.8 times compare to the existing setup [18]. To reduce the negative effects a multiple heat source was implemented and finally, developed minimum thermal resistance was achieved than compare to the Al6063 Alloy [19]. For all the working fluids the rate of increase in heat transfer was 10%, to evaluate this heat exchanger at the model was developed and model was agreed very well with the experimental data [20].…”

Heat pipe is a device to enhance the performance of heat transfer, in particular to transition phase change process. The present investigation is carried out to measure the thermal performance of a closed loop acetone filled oscillating heat pipe with four turns is fabricated and tested. The test was carried out for the inner diameter of 1.7 mm copper tube by varying the acetone of 50%, 60%, 70% and 80% filler ratio with a heat input of 15 W to 40 W in steps of 5 W has been considered. The results shows that 80% acetone filled OHP provides the better thermal performance with an average minimum temperature difference between condenser and evaporator by 6.03%, heat transfer coefficient increased by 77% and the thermal resistance decrease by 43% respectively. The mathematical modelling was developed to predict the performance of the heat transfer. The model clearly shows that the independent variables are statistically significant with a p-value of 0.05 and the uncertainty analysis between the experimental and predicted values are less than 10%.
