Controlling the temperature of electronics under harsh conditions is important for vehicular, aerospace, and other industrial applications. Phase change materials (PCMs), such as paraffin, use latent thermal energy storage (LTES) to store large amounts of latent heat over small temperature ranges, and are being investigated for use in industrial sectors. However, PCMs have low thermal insulation capabilities so porous matrices with low thermal conductivities are often used to decrease the ...
This study suggested the use of capric acid–palmitic acid–stearic acid ternary eutectic mixture/expanded graphite (CA–PA–SA/EG) composite phase change material (PCM), as a low-temperature heat storage material. With a mass ratio of CA:PA:SA = 79.3 : 14.7 : 6.0, the mixture was prepared and its mass ratio compared to that of the CA-PA-SA/EG composite could reach as high as 90%. The melting temperature of the CA-PA-SA/EG composite was ...
A novel composite phase change material (PCM) composed of LiNO3/KCl with expanded graphite (EG) as a filler was prepared and investigated to determine if it had potential for use in solar energy storage applications. The addition of the expanded graphite did not significantly alter the melting temperature in comparison with the eutectic LiNO3/KCl PCM; however, the latent heat of fusion did significantly decrease with increasing mass fractions of ...
