“…These heat transfer paths can enhance the heat transfer performance of the original PCM as well as make the heat distribution of the metal foam‐based FSPCM more uniform. For example, Lei et al 12 found that heat transmission performance of metal foam‐based FSPCM is superior compared to that of nanoparticle‐doped PCM, and the heat distribution of metal‐based is more uniform. Wang et al 13 evaluated the impact of the proportion of copper foam in composite PCMs on heat transmission.…”

Phase change materials possess the merits of high latent heat and a small range of phase change temperature variation. Therefore, there are great prospects for applying in heat energy storage and thermal management. However, the commonly used solid‐liquid phase change materials are prone to leakage as the phase change process occurs. To address this drawback of solid‐liquid phase change materials, researchers have developed form‐stable phase change materials. There are three main strategies for preparation of form‐stable phase change materials. The objectives of this article are: (1) The form‐stable phase change materials are classified according to the preparation strategy, and the properties of each class of form‐stable phase change materials are presented. (2) The advantages and disadvantages of form‐stable phase change materials are also discussed. (3) It is also summarized that the methods to improve the drawbacks and enhance the characteristics of form‐stable phase change materials. (4) Moreover, the multifunctional form‐stable phase change materials are also described. (5) Finally, applications of form‐stable phase change materials are analyzed and discussed.

“…Senobar et al compared the effect of nanoparticles and metal foam on improving the TC of RT44HC and found that the TC of metal foam was better. Lei et al compared the TC improvement effect of metal foam and nanoparticles on PCMs, and found that the effect of metal foam on improving TC was more obvious, and the temperature nonuniformity of PCM was reduced. However, the summary of these studies on PCMs is not comprehensive enough.…”

The use of cold storage devices to store energy at low peaks of power usage and release it at peaks is an economic measure. It is also one of the main means to solve the imbalance between electricity shortages during the day and abundance at night. Adding cold storage balls equipped with phase change materials (PCMs) into water cold storage devices can utilize the sensible heat of water and the latent heat of PCMs for cold storage, which has a high energy storage density and can provide cold water with a suitable temperature. PCMs can be divided into organic phase change materials (OPCMs) and inorganic phase change materials (IPCMs), but both have defects. Adding additives or other materials to them to form composite phase change materials (CPCMs) can obtain suitable thermal properties. In the process of material application, some PCMs have problems of poor thermal conductivity (TC) and liquid leakage. The use of additives such as expanded graphite (EG), metal foam, and nanoparticles is a better solution to the above problems. In recent years, many scholars have researched PCMs and additives for increasing thermal conductivity (AITC). However, there is still a lack of detailed comparison among EG, metal foam, and nanoparticles. This article will introduce the PCMs used in the temperature zone (TZ) of cold storage air-conditioning systems (CSASs) and analyze their advantages, disadvantages, and improvement methods. This paper will focus on the latest research on the effect of additives such as nanoparticles, EG, and metal foam on the TC of PCMs. It will also compare the special effects of AITC in preventing supercooling, preventing phase separation, preventing leakage of liquid PCMs, and flame retarding. The future research directions of AITC will be discussed.

“…The introduction of fillers is an effective measure. Expanded graphite [14,15], metal foams [16,17], graphene [18], boron nitride [19], carbon fibers [20,21], metal fibers [22,23], metal meshes [24], copper nanowires [25], carbon nanotubes [26], etc. have been reported with a significant improvement for the heat transfer coefficient of the composited PCM.…”

In this paper, the thermal management of missile-borne components in a flight state is studied. Avoiding excessive component temperatures under the high-temperature circumstances brought by aerodynamic heat is a requirement to guarantee the equipment’s safe and reliable operation. In this work, we designed four finned shell constructions for a phase change module using the phase change temperature control method and then studied their effects on the module’s ability to dissipate heat using an experimental approach. Three sizes of 30 mm, 40 mm, and 50 mm heating pads were used to replicate heat sources with various heat flux densities and heat dissipation regions, with reference to the heating characteristics of various chips. The results demonstrated that the square-shaped fin had the best heat dissipation effect after operating for 10 min under the power of 10 W and 20 W, while the strip-shaped fins exhibited the highest performance under the power of 30 W. The square-shaped fins had the best heat dissipation effect when reducing working time to 5 min. This paper proposes the optimal fin scheme under different power densities, as well as an enhanced heat dissipation idea for the melting process of the phase change materials based on the test results.
