Preparation and thermal conductivity enhancement of composite phase change materials for electronic thermal management

Experimental study on a novel battery thermal management technology based on low density polyethylene-enhanced composite phase change materials coupled with low fins

“…Although the excellent performance of the as-prepared L-CPCM has been demonstrated in the above results, heat absorbed by PCM cannot be transferred to the external air environment effectively in a practical airtight space due to the low heat transfer coefficient between air and PCM [38]. As we know, Biot number (Bi) can be used to evaluate the ratio between external and internal heat transfer resistance of the battery pack as follows:…”

“…On the other hand, single PCM-based cooling technology usually presents low surface heat transfer coefficient between PCM and air. Thus, thermal energy stored by PCM cannot be transferred to the external air environment effectively, resulting in a decreasing cooling effect during long-term/harsh working cycles [38]. Therefore, to address the above issues, a novel BTM technology was developed based on the ternary composite materials of EG, PA and low-density polyethylene (LDPE) coupled with low fins.…”

Experimental investigation of the thermal control effects of phase change material based packaging strategy for on-board permanent magnet synchronous motors

“…Passive thermal control method exploiting thermal energy storage of phase change materials (PCMs) relied on their considerable latent heat has attracted increasing attentions [15] in certain occasions in that no extra power sources or places for complicated circle system are available especially in the air and space applications. Furthermore, the temperature of the PCM remains more or less constant during its phase transition process where the temperature control [16]. Possessing such outstanding thermal characteristics, the PCM-based strategies have exhibited excellent performance for thermal management area [17].…”

Designing behenic acid microcapsules as novel phase change material for thermal energy storage applications at medium temperature

“…Among the PCM‐developing techniques, encapsulation allows easy and effective integration into many applications . Encapsulated PCMs in macro, micro, and nano sizes can be used in several applications, such as energy saving in buildings, transportation of food and medical stuff, smart textile applications, and electronics …”
