Diabatix ColdStream

ColdStream is a cloud-native platform that transforms how you approach thermal management and cooling challenges. Instead of manually iterating through designs, you define your boundary conditions and let the generative design engine create optimized cooling structures for you. It handles everything from liquid cooling and heat sinks to complex battery thermal management systems, ensuring your components stay within safe temperature limits while minimizing pressure drop and material use.

You can move from initial concept to a high-fidelity, manufacturable design in a fraction of the time required by traditional CFD methods. The platform is built for engineers in industries like automotive, aerospace, and electronics who need to solve extreme heat dissipation problems. By moving your thermal simulation to the cloud, you eliminate the need for expensive local hardware while gaining access to powerful optimization algorithms that explore design possibilities you might never have considered manually.
