Advanced Thermal Management for High-Power Electronics
Abstract
Rapid growth of high-power electronic devices such as power converters,
electric vehicle drives, RF amplifiers, data servers and LED systems has
created serious challenges in heat dissipation. Excess heat generation reduces efficiency, reliability and life of electronic components. Traditional air cooling and simple heat sinks are now not sufficient for modern compact and highdensity electronic packaging. Advanced thermal management techniques are therefore essential to maintain device temperature within safe limits. This paper reviews the recent developments in thermal management methods including advanced heat sinks, heat pipes, vapor chambers, liquid cooling, phase change materials, microchannel cooling, thermoelectric cooling and emerging
materials such as graphene and diamond composites. The paper also discusses the importance of thermal interface materials and design considerations for effective heat removal. Tables are provided to compare different cooling techniques. The study highlights that integration of multiple cooling methods and material innovation is key to managing thermal issues in next generation electronics.
KEYWORDS: Thermal management, high-power electronics, heat sinks, heat pipes, liquid cooling, phase change materials, microchannels, thermal interface materials.
