单相浸入式冷却:定制的理想选择
首先,区分单相和双相浸入式冷却装置非常重要。
In single-phase immersion cooling, hardware is submerged in a dielectric fluid that makes direct contact with the IT equipment, conducting heat away as the fluid flows through a heat rejection mechanism, such as a heat exchanger, which is typically operated with facility water.有机流体或卤化流体均可用于此用途,但后者通常成本较高,环境可持续性较差。
In two-phase cooling, a fluorocarbon-based fluid readily boils when in contact with equipment hot spots, transitioning the fluid from a liquid to a vapor that can be condensed in a heat exchanger and recirculated into the cooling tank.这种液态到气态的相变可使流体从设备中吸收大量热量,但同时也需要集成系统设计元素以促进转换,此外还需要密封系统来防止因蒸发而造成代价高昂的流体损失。
与传统系统相比,单相和双相系统均具有更高的效率、高密度性能和冷却特性。 However, there is significant potential to tailor the fluid in a single-phase system, creating an opportunity for solutions that meet the needs of future hardware.
