Selecting a Thermal Management System Supplier for Aerospace and Defense Applications

Selecting a Thermal Management System Supplier for Aerospace and Defense Applications - Aircraft Image - Parker AerospaceToday’s sophisticated aerospace and defense electronic systems are driving significant increases in power densities, resulting in complex thermal management challenges. Advances in semiconductor manufacturing continue to raise the watts per square inch paradigm — multiple devices in close proximity and kilowatt levels of heat dissipation. Directed energy weapons are now a reality as laser diodes and enabling fiber optics to bring total heat dissipations into the tens of kilowatt range.

Whether you are a thermal design engineer looking for an efficient, dependable cooling solution to perform in the most extreme, mission-critical applications, or a program manager focusing on procuring a solution at the lowest risk and lowest cost, selecting the right thermal management system provider is critical to performance and safety. This blog offers important factors to consider when choosing a thermal management system partner.

 

Product range and performance

What is thermal management? In simple terms, it is collecting heat in one location and then transporting it to a place where it can be safely rejected. A typical system will consist of some kind of cold plate (or liquid-cooled enclosure) and a plumbing system that will move the liquid or liquid/vapor mix to where the heat exchanger is located. The heat exchanger can be a simple radiator (in the case of a liquid-to-air heat exchanger) or something more complex such as a liquid-to-liquid heat exchanger. Any system solution is totally dependent upon the platform and the environment. Components are needed to collect (cold plates); move (pipes, connectors, and pumps), and dissipate (heat exchangers) the heat. Therefore, designing an efficient and SWaP (size, weight, and power ) focused solution requires a wide-ranging portfolio of components and systems experience as well as the engineering know-how and design flexibility to tackle today’s highly complex thermal management challenges.

 

Experience

Thermal management is not new, but today's technological advances and the need to utilize them bring the discipline into sharp focus. Selecting a thermal management supplier is a challenge. Consider that most of the solutions that have been developed over the past decade have resulted in a proprietary design as part of a commercial solution or are deeply secretive with a system deployed for defense purposes. To that point, datasheets and press releases cannot be generated for systems that reside on high altitude UAVs or aircraft. To gain an understanding of expertise in this environment, the supplier's engineering reputation, qualifications of the team, and proven track record of success should be examined. 

 

Efficiency and cost effectiveness

Enabling a design approach at the highest possible (system) level will always achieve the most efficient solution in both cost and performance; hence, the term thermal management. An in-depth knowledge of each of the components and sub-assemblies that comprise the complete system ensures maximum efficiencies at the points of interconnection. Advanced manufacturing techniques support the requirements for a better SWaP and also enable shorter times to market. This provides an engineered solution from concept to support. A one-supplier solution will maximize efficiency and keep overall program costs in check. 

 

Support

Whether you are designing, manufacturing or servicing, global support is an inevitable need. Be sure your supplier provides a full spectrum of global service and support around the clock — wherever and whenever you need it.
