Abstract: ABSTRACT Thermal management remams a critical challenge m modem laptops due to increasing computational power, compact form factors, and reliance on active cooling systems that introduce noise, dust accumulation, and energy inefficiency. This work proposes a novel self-cooling laptop architecture employing phase-change microchannel technology integrated directly within the chassis and thermal hotspot regions of the device. The proposed system utilizes micro-fabricated channels filled with a phase-change material (PCM) strategically distributed based on the thermal profile of the processor, graphics unit, and power management components. During high computational loads, the PCM absorbs excess heat through latent heat storage by undergoing a solid-liquid phase transition, thereby maintaining operating temperatures within safe limits without the immediate need for active cooling. When thermal demand decreases, the stored heat is gradually released and dissipated through the laptop enclosure, restoring the PCM to its original phase. Unlike conventional fan-based cooling solutions, the proposed approach operates silently, reduces power consumption, and enhances device reliability by minimizing mechanical components. The integration of microchannels within structural elements enables efficient heat transfer without compromising portability or structural integrity. Additionally, the adaptive nature of the phasechange process allows the system to respond dynamically to fluctuating workloads. This selfcooling mechanism presents a sustainable and energy-efficient alternative for next-generation laptops, offering improved thermal stability, extended component lifespan, and enhanced user comfort, making it highly suitable for hi~performance and compact computing devices.
