Abstract
Feasibility study of liquid cooling systems for controllers of disk array systems, which generates high-density heat in the chassis, is conducted. Low-height prototype radiator suitable for narrow channels is developed, and its thermal performance is evaluated. The prototype radiator is possible to dissipate about 180W at water flow rate of 300mL/min, frontal air velocity of 2m/s and temperature difference of 35 degree. Then the cooling performance of prototype liquid cooling system using the radiator is evaluated. Prototype liquid cooling system using brain frozen at -20 degree Celsius as a working liquid is able to cool controllers of about 150W heat generation, at frontal air velocity of 2.5m/s and ambient temperature of 35 degree Celsius. It is almost double the cooling performance that obtained by conventional forced air-cooling.
