Experimental analysis of phase change phenomenon of paraffin waxes embedded in copper foams

Experimental investigation on thermal performance of phase change material coupled with closed-loop oscillating heat pipe (PCM/CLOHP) used in thermal management

“…At present, the methods enhancing the heat dissipation of PCM can be mainly divided into two categories. One is increasing the thermal conductivity of PCM by adding high thermal conductive particles or fillers to fabricate composite PCM, such as paraffin wax/expanded graphite (paraffin wax/EG) [5,6], paraffin wax/metal foams [7][8][9], and paraffin wax/nano-materials [10,11]. The other one is placing high thermal conductivity inserts into PCM through structure design, such as aluminum fins [12,13], capillary driven heat pipe, gravity assisted heat pipe (GHP) [14][15][16][17][18][19], and others.…”

Concepts and Challenges of Nanofluids and Phase Change Material (PCM) in Photovoltaic Thermal (PV/T) Collectors: A Review

“…Figure 2 shows the method followed in producing nanofluids. Materials that absorb and release heat at constant temperature using the solid-liquid Phase change process, are known as Phase Change Materials (PCMs) (Mancin et al 2015;Qiu et al 2015). They can store and release high amounts of thermal energy with insignificant variation in temperature, which makes PCMs widely used in thermal storage (Zalba et al 2003).…”

Application of Hybrid PCM Thermal Energy Storages with and without Al Foams in Solar Heating/Cooling and Ground Source Absorption Heat Pump Plant: An Energy and Economic Analysis

“…They consist of a stochastic distribution of interconnected pores almost homogenous in size and shape, allowing a high heat transfer area per unit of volume and high thermal conductivity [7]. Mancin et al [8] carried out some experiments measuring the improvement of the heat transfer by a metal foam during the solid-liquid phase change process of different paraffin waxes. More recently, Lazzarin et al have conducted an extensive campaign measuring the temperature distribution and loading and unloading times of hybrid water PCM TES with and without aluminum (Al) foams [9][10][11].…”
