Abstract.
Considering the explosive proliferation of small electronic devices, effective heat management now ceases to be an optional feature but a serious design requisite. Power electronic modules, IoT platforms, and modern embedded devices often operate continuously under severe heat stress, with limited airflow and physical space. These is difficult for conventional air-cooling methods to achieve which leads to decreased performance, thermal instability, and long-term reliability problems. This work describes a hybrid adaptive cooling system using a Peltier module for thermoelectric cooling, liquid-based heat extraction, and a proprietary coolant scientifically designed and managed by sophisticated PID and PWM algorithms. The system integrates relay-based fail-safe protection, optocoupler-isolated power electronics, and Bluetooth-enabled real-time telemetry for safe and dependable operation. In parallel, a novel Internet of Things (IoT)-based thermal conductivity testing device was developed to evaluate various distilled water–ethylene glycol (DW–EG) coolant combinations scientifically using Fourier's heat conduction concept. A 70:30 DW–EG mixture provides the optimal balance of thermal conductivity, viscosity, chemical stability, electrical safety, and pump efficiency, according to experimental results. This proposed system represents an advancement of the conventional concept of cooling. The new one offers tighter temperature control, more stability, and fewer operational costs, which make it perfect for compact embedded electronics.
