Advanced Pumps and Cold Plates for Two-Phase Cooling Loops, Phase II

Advanced instruments used for earth science missions require improved cooling systems to remove heat from high power electronic components and maintain tight temperature control for sensitive instruments. Mesoscopic Devices proposes to develop a pumped two-phase cooling loop that will provide high heat flux, distributed load cooling (> 100 W/cm^2) in a lightweight system. In Phase I, an extremely compact pump optimized for two phase cooling was demonstrated, along with advanced lightweight cold plates. Pump and cold plate advances in Phase II will further reduce the mass and improve reliability. A complete thermal loop will be constructed and tested to demonstrate the improved pumps and cold plates.

This is a mature technology (TRL 7+) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
