Thermal management is a crucial element in ensuring the effectiveness and lifetime of an avionic system. Like other electronic systems, avionics systems typically reach incredibly high temperatures during regular operation, limiting the components’ lifetime and efficiency while placing stress on PCBs. As mechanical systems replace electronic systems, the new systems need a design to withstand high mechanical and thermal demands.
Those systems use less power, mass, and volume while simultaneously integrating various functionality. Creative thermal management will not only solve extreme temperature issues but provide engineering opportunities for designers of PCBs and electromechanics.
The goal of thermal management is to transfer heat away from critical components. During the process, heat dissipates into the external environment. Different active and passive heat transfer techniques make up a part of thermal management. Natural convection efficiently removes high heat and keeps crucial components within operating limits.
The significant challenges that plagues electronic and cooling systems in avionics and the military are the need to efficiently transport heat away from systems while maintaining low power and weight. Passive cooling techniques take heat away from hot components at the board level. Heat is removed from a high-temperature system and moved to cooler areas at the cooling system level.
Aerospace and defense standards conform to a strict design and manufacturing standard while designing avionics and defense systems. Some of the standards that meet quality, manufacturability, and reliability as specified by relevant organizations include IPC, SAE, and ISO.
MIL is another standard that conforms to functionality and reliability in an avionic system. It is also essential to ensure that the thermal management system meets high standards, relying on a highly skilled and experienced service provider to provide optimal thermal management solutions.
There are several cooling options available to dissipate heat generated by UAV electronics. Some of these include heat sinks, fans, and forced air systems.
