“…The study and development of PCMs that demonstrate high performance is of great significance in developing more efficient routes of energy storage, supply, and demand. In the past few decades, PCMs have attracted great attention that sparked numerous investigations from research groups [5][6]. The majority of the PCMs investigated by researchers are classified as organic PCMs, such as paraffin wax and non-paraffin organic compounds [7][8][9][10][11]; meanwhile, inorganic PCMs have received relatively little attention.…”

Calcium chloride hexahydrate(CaCl 2 •6H 2 O) composites PCMs containing strontium chloride hexahydrate (SrCl 2 •6H 2 O) and oxidation expandable graphite(EGO) were prepared and phase change behavior of CaCl 2 •6H 2 O/EGO/SrCl 2 •6H 2 O composite PCMs, including supercooling degree, phase change temperature, latent heat, density, thermal conductivity and thermal stability were systematically studied. Results demonstrate that thermal conductivity, heat transfer and the latent capacities of the CaCl 2 •6H 2 O/SrCl 2 •6H 2 O/EGO composite PCMs are significantly enhanced, supercooling of CaCl 2 •6H 2 O/SrCl 2 •6H 2 O/EGO composite PCMs are suppressed, mainly ascribe to that the EGO are homogenously dispersed in PCMs due to the existence of oxygen-containing functional groups in EGO, meanwhile, the well-dispersed EGO serving as nuclei to promote the heterogeneous nucleation and crystallization process of CaCl 2 •6H 2 O. Moreover, a fifty-run-cycling test verifies that the CaCl 2 •6H 2 O/SrCl 2 •6H 2 O/EGO composites PCMs contained with 3wt.% SrCl 2 •6H 2 O, and 1.0wt.% EGO possesses enhanced thermal behavior with no phase segregation observed; the latent heat was calculated to be 172.26 J/g.

“…Another numerical study by Wang et al [75] explored some key factors affecting the thermal performance of PCM-based multi-fin heat sinks and reported that such heat sinks would be favorable for maintaining stable operational temperature in electronic devices. However, while researchers such as Fok et al [76] and Kalbasi et al [77] concur that PCM-based systems with internal fins are potentially pragmatic solutions for electronic device cooling, its proper implementation is still subject to optimizations in terms of the quantity of PCMs, number of fins, power level of the heat source, etc. In order to improve the thermal conductivity of passive thermal management systems, Hafiz et al [78] used pin-fins in an neicosane-based circular heat sink.…”

Due The portable electronic devices in everyday life have been getting increasingly compact day by day, and with the advancement in wireless technology, they are expected to facilitate multitasking. In this context, efficient heat dissipation to maintain consistent thermal performance has become quite a challenge. Phase change materials (PCMs) have emerged as a viable option to eliminate problems regarding the thermal management of compact electronics. This review looks into the different types of PCMs investigated by researchers so far, especially in the case of cooling compact electronic devices. It also discusses the parameters critical to its efficiency and implementation, encapsulation, etc. The merit of internal fins, nanomaterials, and metal foams as thermal conductivity enhancers along with shortcomings in the current literature have also been noted in this review.

“…The results showed that the fin effectiveness and the melting enhancement ratio had a proportional relation with the number of fins. Kalbasi and Salimpour proposed a two‐dimensional model to investigate the employment of vertical and horizontal fins inside an aluminum heat sink filled with RT27 as a PCM. The authors validated the numerical model with the experimental data obtained from Kalbasi and Salimpour and Hosseinizadeh et al .…”

Summary The shortage in energy resources combined with the climb in greenhouse emissions is the main incentive beyond the deployment of solar energy resource in various applications. One of the most successful applications is the utilization of solar energy in the domestic water heating systems (DWHS) because 70% of the consumed energy in the residential segment is utilized for space heating and appliances in cold climates . However, the full deployment of solar energy in domestic water heating is only possible when an energy storage system with acceptable price is available. Recently a new tendency for deploying phase change materials (PCMs) as an energy storage system is introduced in several solar DWHS. These systems are known as integrated PCM in solar DWHS and offer several advantages including high storage capacity, low storage volume, and isothermal operation during the charging and discharging phases. The present study reviews various techniques utilized for integrating the PCM in solar water heating systems and the utilized methods for enhancing the heat transfer characteristics of the PCM through the usage of extended surfaces and high conductive additives.
