“…The maximum and minimum increment of decomposition temperatures are about 4.38% and 0.166%, respectively, among the different nanocomposite PCMs. The improvement in thermal stability of the nanocomposite PCM is due to the improvement in specific heat capacity and improved TC, as both enhance the uniform heat distribution in the PCM 25,35 …”

Summary This experimental work discusses the thermophysical investigation of metallic nanocomposite PCMs having a potential application in indoor thermal management. Organic fatty alcohol (lauryl alcohol) was used as a phase change material (PCM). Four metallic nanoparticles, namely Al2O3, CuO, Fe3O4, and SiC at the concentrations of 1 wt%, 3 wt%, 5 wt%, were used to prepare nanocomposite PCMs, and their phase change properties were investigated. The results showed a minor change in the phase change temperatures, and the latent heat values varied between 6.56% and 18.5%. Besides, the degree of supercooling was reduced for nanocomposite PCMs. Fourier transform infrared spectroscopy, and thermogravimetric analysis showed no chemical reaction between the nanoparticles and the base PCM. The nanocomposite PCMs decomposed above 110°C, higher than the proposed application temperature range. In addition, the maximum enhancement in thermal conductivity of PCM at 10°C with 5 wt% of Al2O3, CuO, Fe3O4, and SiC nanoparticles were about 29.1%, 52.2%, 9.2%, and 17.9%, respectively. The endothermic freezing process was carried out, and lower phase change duration was recorded for nanocomposite PCMs compared to pure PCM. Based on various experimental studies, Al2O3 and CuO nanocomposite PCMs exhibits significantly improved thermal and physical properties than the Fe3O4 and SiC nanocomposite PCMs and can be used as a potential thermal energy storage material for indoor thermal comfort applications.

“…This problem must be overcome to guarantee operation at low temperature but for a very long period compared to that guaranteed by addition of single nanoparticles. For this, the addition of hybrid nanoparticles has shown the ability of NePCM to lower the electronic component working temperature and clearly extend the latent heat phase duration where the electronic component operates away from any risk or failure 34 . The hybrid nanoparticles fraction has a significant influence since NePCM with 1%‐Al 2 O 3 and 3%‐Cu has decreased the temperature further compared to that with 2%‐Al 2 O 3 and 2%‐Cu.…”

Summary This article presents two‐dimensional (2D) transient numerical simulation and mathematical modeling of a heat sink based on nano‐enhanced phase change materials (NePCMs) to study their performance for the cooling of an electronic component. n‐eicosane is used as a PCM and Al2O3, ZnO, CuO and Cu are used as nanoparticles in NePCMs. An electronic component is mounted in the center of the bottom wall and which an aluminum fin simulating the role of a substrate (motherboard) occupies. The NePCM completely fills the inner part of the heat sink. The NePCM store the heat generated by the protuberant electronic component. The transient regime is numerically performed adopting the finite volume method and the enthalpy‐porosity technique. It has been found that the mean heat transfer and the fluid flow structure are closely dependent on the nanoparticles type in NePCM. The addition of single NePCM, with volume fractions of 2% and 4%, decreases the electronic component operating temperature and the latent heat phase duration during which the electronic component operates safely. The hybrid NePCM shows a different behavior by decreasing the electronic component operating temperature and increasing the latent phase duration. Compared to pure PCM, by inserting a volume fraction of 4%‐Cu, the electronic component working temperature decreases by 4.69% and the latent heat phase duration decreases by 3.33%. Compared to pure PCM, hybrid nanoparticle insertion of 1%‐Al2O3 and 3%‐Cu showed a 5.77% decrease in the electronic component operating temperature and a 31.11% increase in the latent heat phase duration. By inserting hybrid nanoparticles instead of single nanoparticles, the effective thermal effusivity of NePCM is improved by 10.85%.

“…So, it requires encapsulation of PCM. This weakness of material depending on its nature can be improved using different methods investigating by researchers including increasing the heat transfer area (Aydin et al, 2018), geometric optimization (Yazici et al, 2014), dispersing particles (Arshad et al, 2020), metal matrix (Alhusseny et al, 2020), impregnated graphite foam/matrix (Py et al, 2001), encapsulation (Zhang et al, 2021).…”

An experimental study is performed to investigate the performance (thermally and electrically) of a small-scale li-ion module (3s2p) using passive thermal management strategy of phase change material (PCM)/graphite matrix. The PCM/graphite matrix was obtained by impregnating the graphite matrix (bulk density: 75 g L-1) with phase change material (paraffin/organic, RT-35). The performance tests of a li-ion module are conducted at 1C and 1.6C discharge rates for graphite matrix composite with phase change (phase change composite or PCM/graphite matrix) and also air cooling, comparatively. To illustrate the performance of the PCM/graphite matrix, transient temperature variations, thermal imaging, discharge capacity, and energy capacity are achieved comprehensively. The results illustrate that graphite matrix composite with phase change has a significant contribution to melting heat transfer, operating temperature, utilized capacity, and energy capacity compared to air cooling. Effective thermal conductivity of PCM/graphite matrix is increased 35 times by comparison with pure paraffin. Operating temperature and temperature gradient throughout the li-ion surface decrease by 22 % and 43 % compared to the air cooling, respectively, for high discharge rate. Operating time and energy capacity is increased 33 % and 28% compared to natural air cooling, respectively, for high discharge rate. It is also disclosed that dominant heat transfer mechanism is conduction depending on micro/nano-size porous structure of graphite matrix.
