Microcoolers hold it together under pressure of 250 bars

Leti engineers had a surprise in store for CERN researchers when they recently presented microcoolers they had made for a CERN experiment. While the technical specifications for the microcoolers required pressure resistance of up to 100 bars, Leti’s devices held strong even at 250 bars! And the CERN is looking for even more powerful pumps to test the microcoolers’ limits.

The microcoolers, delivered to the CERN in late 2012, were made by combining two silicon plates using molecular adhesion. Testing of these devices usually looks at pulling strength rather than pressure resistance, so Leti discovered a hidden benefit to its pioneering design. Other applications are being considered, and patents are likely over the horizon.
