Phase change materials (PCMs) are used as latent heat thermal energy storage materials. The fields of application for PCMs are broad and diverse. Among these areas are thermal control of electronic components and thermal building regulations. These areas are used as heat and cold storage materials. The low thermal conductivity of PCMs is one of the significant and severe technological problems of PCMs. This paper presents a review of the latest works using PCMs in the thermal management of electronic components, buildings, and heat exchangers. Besides, it provides concise pieces of information on the classification of PCMs, their advantages, disadvantages, and thermal storage systems.

“…Foam material is a type of porous, lightweight, high-strength, low-density media [1], which has high heat transfer characteristics and strong flow mixing characteristics due to its inherent properties such as high porosity, large specific surface area, disordered pore distribution, tortuous flow path [2]. Hence, foam materials are widely used in various heat exchange fields, including heat exchangers [3], heat sinks [4][5][6], electronic cooling [7], cooling towers [8], volumetric absorbers [9][10][11], catalytic reactors [12,13], etc.…”

Foam materials are widely used in heat exchange because of their high porosity and large specific surface area. Correctly characterizing heat transfer characteristics is the key to ensuring efficient heat transfer. In this paper, single-blow transient test technology is used to experimentally measure the temperature. Silicon carbide ceramics with various thicknesses ranging from 30 to 105 mm and different pore structures were used in the experiments. The test was carried out at the velocity ranging from 0.5 to 1.8 m/s. The air temperature distributions of the inlet and outlet were obtained by processing the experimental data, and the regularity of the average volumetric heat transfer coefficient was obtained and analyzed. Subsequently, the simplified tetrakaidecahedron models with a porosity of 0.85 and 0.75 were used to analyze the heat transfer characteristics. The local thermal equilibrium and local thermal non-equilibrium at the pore scale were analyzed. By comparing the simulation with the experiment, it shows that the larger thickness affects local thermal equilibrium and leads to a decrease in the volumetric heat transfer coefficient. The conclusion can be used to guide the optimization of the design of foam material-mediated heat exchange equipment.

Nowadays electrical power is one of the most vital requirements for daily life and industries. Since with the rise of the human population, providing electrical energy is an important challenge, some methods should be used to reduce the electrical demand or shift the demand from peak-hours to off-peak hours. Ice storage systems are one of the devices which can be used for this purpose. In this article, a transient 3D numerical simulation was carried out to investigate the effects of two geometrical parameters of double helical coil heat exchanger in the charging process of an ice storage system with the volume of 15 L. These parameters were helical coil pitch length and the distance between inner and outer coils. The results indicated that with higher values for pitch length and inner and outer coils distance, compared to smallest values for these parameters, the distribution of formed ice in the storage improves and the rate of ice formation increases by 22.81% and 13.99%, respectively. Increasing these values can also retard the ice block formation which is an undesirable phenomenon in the external discharge process of the ice storage systems.
