High Power Energy & Cooling systems.

New technological developments (like innovative sensors and effectors) for application in systems for defense are getting more and more advanced and move towards higher electrical power usage. Because of demanding constraints (like small integration volume, mobility and extreme operational conditions) these developments also require active cooling power. The new technological developments always require a fitting Energy & Cooling solution to be able to be used in the intended operational context. Since its foundation Demcon defense & security systems has defined development and integration of Energy & Cooling solutions as one of its main competence fields to add value for defense in the role of technology developer and integrator.

highlights

  • complete system design, realization, integration, verification and validation
  • create a powerful digital twin for streamlined electrical and thermal system modeling and dynamic behavior analysis using dynamic lumped-element modeling
  • availability of fully equipped 20-foot container E&C testbed for system testing and verification

advanced energy integration.

In the past years Demcon defense & security systems gained experience with designing, integrating and testing of high-power energy solutions within the context of the bi-national Jupiter program. This resulted in a for development required 20-foot container based E&C testbed and a in a Boxer vehicle integrated E&C system taking care of the demanding power and cooling supply of a high power HEL effector system.

electrical and thermal systems development

safe solutions for effective equipment.

Electrification is the name of the game in the military world. Personnel, vehicles and installations are increasingly equipped with electric devices and systems for operational tasks and communications. As a result, electric power supply and cooling needs are increasing. This is especially true for advanced systems such as lasers that require a high-capacity energy supply within a small footprint. To develop the required energy and cooling systems, we combine our systems engineering skills with specialized thermal and electrical disciplines and extensive production capabilities.

we power advanced operations.

We have the required mechanical, thermal and electrical power expertise, and in-depth knowledge of the various processes. This is demonstrated by our thermal management track record in high-tech, aerospace and logistics applications. For example, we have specialized in lumped-element modeling to understand and predict the operation of complete energy and cooling solutions. In addition, our in-house experts on computational fluid dynamics and finite-element modeling can make detailed energy-flow simulations. Next to this we have built a network of key subsystem and component partners and suppliers. This enables us to develop reliable systems for operations in the military arena.
