Peltier-Cooled Air Injection and Condensation Simulation in PA Equipment

The Peltier module is a powerful tool for local cooling of small electronic equipment. However, when injecting Peltier-cooled air into PA (Power Amplifier) equipment, the risk of condensation increases along with the cooling effect. In this post, we will look at how condensation forms inside PA equipment when Peltier-cooled air is injected, based on simulation examples, and introduce key design points to prevent it. Condensation occurs when moisture in the air turns into water droplets on cold surfaces. If the cooled air drops below the dew point, water droplets will form on metal surfaces and circuit boards inside the equipment, potentially causing short circuits, corrosion, and insulation failure. Therefore, condensation simulation and dew point management are essential in the design of cooling air injection systems.     Simulation Conditions for Peltier-Cooled Air Injection Key conditions used in the simulation: Outdoor conditions : 28°C, 70% relat...
