microchannel
/ˈmaɪ.kroʊˌtʃæn.əl/
Definition
A microscopic passage embedded within a material, such as a silicon chip, designed to circulate liquid coolant for the purpose of heat removal.
Etymology
Derived from the Greek 'mikros' meaning small and the Old North French 'chanel' meaning a pipe or watercourse. The combination reflects the modern engineering practice of miniaturizing fluid-conveyance systems.
In the news
In this article, microchannels are used to circulate water directly inside semiconductor chips to combat the intense heat generated by high-performance AI processors. By creating these tiny internal pathways, researchers significantly improved cooling efficiency and reduced the energy needed to move the coolant.
