Researchers Demonstrate In-Chip Watercooling

FallOutBoyTonto shares a report from Ars Technica: Part of the problem with liquid cooling solutions is that they're limited by having to get the heat out of the chip and into the water in the first place. That's led some researchers to consider running the liquid through the chip itself. Now, some researchers from Switzerland have designed the chip and cooling system as a single unit, with on-chip liquid channels placed next to the hottest parts of the chip. The results are an impressive boost in heat-limited performance. There have been a number of demonstrations of on-chip liquid cooling. These typically involve a system where a device with a set of liquid channels is fused onto a chip, and a system pumps fluid through it. This can get heat off the chip, and initial implementations have found that there's a bit of a trade-off: it takes more power to pump the water through these channels than you extract from the processor. That power isn't used at the site where heat is an issue, so it doesn't get in the way of the heat dissipation, but it does cut into the energy efficiency of the system. The new research builds upon these ideas to boost the efficiency of on-chip cooling systems. And the researchers involved demonstrate that it works using a power-converting chip that otherwise would see the performance reduced by the heat. The research has been published in the journal Nature.
