Due to its high self‐heat rate, most researchers have avoided using lithium cobalt oxide (LiCoO2) in their work, although, major car companies use it to power some car models because of its high‐power density. A thermal management system benefits from phase change material (PCM) and serves as a reliable cooling system to ensure the safety, performance, and lifespan of Li‐ion batteries. In this study, we conducted an experimental investigation of a new hybrid battery thermal management system (BTMS) using PCM combined with aluminum fins and forced air to enhance the cooling performance of Li‐ion battery type 18 650 LiCoO2. Furthermore, the hybrid model's thermal behaviors are compared with other models that use only air or PCM for cooling. The cooling performance of different BTMS models was tested under a high temperature of 40°C and various discharge rates, as well as, various air velocities. The results demonstrate that the hybrid model effectively minimizes the battery heat accumulation and can reduce the maximum operating temperature by 1.5°C, 5.5°C, and 9.5°C compared to the air‐cooling model and by 2.8°C, 5.1°C, and 16.1°C compared to the PCM model for discharge of 1C, 2C, and 3C rates, respectively. Furthermore, the maximum temperature difference within the battery pack did not surpass 3.1°C with our hybrid model. Moreover, the use of our model has a significant advantage in minimizing the air‐cooling power consumption by 89%.

“…The results indicate that the efficacy of the novel model surpassed that of the conventional v-corrugated absorber plate. The efficacy of a single-pass solar air heater thermal collector was examined in research conducted by (Alomar et al, 2023), whereby the inclusion of permeable material and an expanded area was investigated. The results indicated that Model 2 had the maximum efficiency level, reaching 67%, while Model 1 obtained an efficiency of 60% at a mass flow rate of 0.02 kg/s.…”

The use of a V-corrugated plate absorber in a sun drying system (SDS) under the weather in Baghdad is the subject of this study's original investigation. Analysis of the effects of this novel design is the main goal of the research. To investigate temperature fluctuations inside the drying chamber, experimental tests were run. Initial temperatures for the V-shaped and flat plate designs were 47 °C and 43 °C, respectively, at 8:00 am. At 1:00 pm, when the sun's beams are vertically aligned and the solar radiation reaching the glass collector is at its highest, both arrangements experience temperature peaks. The sun's rays' shifting angles caused temperature drops after this peak, which reached minimums of 47 °C and 41 °C for the V-shaped and flat collector configurations, respectively. It's interesting to note that, compared to the flat plate design, the V-corrugated plate absorber continuously maintained higher temperatures throughout the day. Notably, the absorber showed improvements of 11.6 %, 19.2 %, and 14.6 % at the appropriate times. The study also emphasised the enhanced heat transfer efficiency of the V-shaped absorber, which was attributable to its capacity to withstand greater temperature differences between the input and output. Surprisingly, the V-shaped absorber outperformed efficiency values at 8:00 am and 5:00 pm by 73 % and 82 %, respectively, and reached a maximum thermal efficiency of 71% at 1:00 pm. The investigation focused on a significant 29 % performance differential between the two systems at 1:00 pm, when heat extraction is at its best. This finding highlights the effectiveness of the V-corrugated plate absorber in increasing energy efficiency. The study's findings emphasise the creativity and practicality of V-corrugated plate absorbers in enhancing the efficacy of sun drying systems, particularly in adverse weather situations.

This current investigation involves an experimental inspection of adding porous medium and phase change material (PCM) above the absorber surface to enhance the performance of a single slope and single basin solar water distiller system. To demonstrate the effectiveness of adding porous medium and PCM, the performance of the modified system and conventional system is compared under similar operating conditions. The system that uses porous medium and PCM is called MSS‐FPP, whereas the conventional system is called MSS‐F. Rectangular fins are fixed above the absorber plate for both models. For MSS‐FPP model, three different types of porous medium (stones, nuts, and black glass balls) are used in addition to paraffin wax filled inside circular tubes as a PCM. The data are collected in November and December 2023 in Mosul City, Iraq. The experiments are carried out under different water depths. The findings confirm that the performance of MSS‐FPP model is better than MSS‐F model by 41.32% (for water depth 3 cm) and 30.61% (for water depth 5 cm). The results also indicated that the water productivity of MSS‐FPP model is higher than MSS‐F model by 41.67% (for water depth 3 cm) and 30.65% (for water depth 5 cm). For MSS‐FPP model, the maximum water productivity and efficiency are obtained when using black glass balls as compared to nuts and stones types, where the highest water temperature and water productivity values are found equal 54°C and 1.01 kg/m2 for water depth 3 cm. The enhancement in the performance of modified solar water distiller system (MSS‐FPP) shows that using a porous medium and PCM has considerable impacts on the evaporation rate, heat exchange, and rate of heat transfer.
