A review of phase change materials (PCMs) in electronic device cooling applications

Abstract

Due The portable electronic devices in everyday life have been getting increasingly compact day by day, and with the advancement in wireless technology, they are expected to facilitate multitasking. In this context, efficient heat dissipation to maintain consistent thermal performance has become quite a challenge. Phase change materials (PCMs) have emerged as a viable option to eliminate problems regarding the thermal management of compact electronics. This review looks into the different types of PCMs investigated by researchers so far, especially in the case of cooling compact electronic devices. It also discusses the parameters critical to its efficiency and implementation, encapsulation, etc. The merit of internal fins, nanomaterials, and metal foams as thermal conductivity enhancers along with shortcomings in the current literature have also been noted in this review.

Recent Progress in Polyethylene‐enhanced Organic Phase Change Composite Materials for Energy Management

“…Since electronic devices often generate heat where excessive heat cause damage and dysfunctionality of the devices leading to reduced and poor performance and safety issues [127–129] . While the conventional cooling systems are usually energy consuming and bulky in size and weight, researchers investigated the utilisation of PCMs in electronic devices such as mobile phones, batteries to keep temperature fluctuation to a minimum by absorbing or releasing excess heat as needed [115,130–132] . So PCMs are much demanded especially for small volume, small space or portable electronic devices, such as phones, lap‐tops, MEMs chips and other portable detective equipment [133,134] .…”

“…[127][128][129] While the conventional cooling systems are usually energy consuming and bulky in size and weight, researchers investigated the utilisation of PCMs in electronic devices such as mobile phones, batteries to keep temperature fluctuation to a minimum by absorbing or releasing excess heat as needed. [115,[130][131][132] So PCMs are much demanded especially for small volume, small space or portable electronic devices, such as phones, lap-tops, MEMs chips and other portable detective equipment. [133,134] Moreover, using PCMs is much energy efficient compared to the comment cooling systems such as fan or liquid cooling, which is adding more complications to the electronic system while not environmental friendly.…”
