IMMERSION THERMAL MANAGEMENT SYSTEM WITH MAGNETO-RHEOLOGICAL PUMPING

Abstract

Immersion system (100) for data centers comprising a dielectric fluid (20) with encapsulated PCM with a melting point of 55-65°C and Fe3O4 particles <50nm, graded porosity heat sinks from 100µm to 10µm (40), and external inductors (70) that generate magnetorheological waves at a frequency of 50-200 Hz to move the fluid without the need for mechanical pumps. It includes a thermal interface with aligned graphene (50). The system operates with a PUE of 1.05, pumping power consumption of 0W, and an MTBF greater than 100,000 hours.
