DARPA wants to prevent overheating in military chips


The military venture capital wing wants to fund technology that controls the flow of coolant fluids in chips, with the goal of preventing overheating in military weapons systems.

The Defense Advanced Research Projects Agency is looking to support scientists in building systems to direct heat with evaporative liquid cooling, as part of an experimental program called ICECool Systems, a notice on reveals. Defense hopes to eventually integrate the technology into the commercial-off-the-shelf devices with the aim of “overcoming the excessive weight and volume, as well as thermally-limited performance, of traditionally-cooled COTS components,” the notice states.

As military technology has gotten more complex, device components have begun consuming more and more power. This has created the risk of heat pockets, degrading their performance.

Cooling strategies that impact performance of chips are strongly discouraged, the notice states. Responses are due Sept. 13.

This isn’t the first time the Pentagon has solicited ideas for managing heat in electronic systems. DARPA’s Thermal Management Technologies program aims to build ways to transport heat emitted by devices, through the development of novel materials and other cooling techniques.

    MIT Technology Review: Flash Storage As a Strategic IT Asset For the first time in decades, IT leaders now consider all-flash storage as a strategic IT asset. IT has become a new operating model that enables self-service with high performance, density and resiliency. It also offers the self-service agility of the public cloud combined with the security, performance, and cost-effectiveness of a private cloud. Download this MIT Technology Review paper to learn more about how all-flash storage is transforming the data center.
