Experimental And Investigation On Noise Of The Cooling System For The Blade Server

The stability of the blade server is very important for consumer. Radiator determine whether or not the work environment is eligibility. The noise of the radiator influence the choice of the consumer. So the IT industry take up with reducing the noise of the electron product.The advantage of the blade server is that it can centralize more server network and memory equipment in the same chest. But the quantity of heat letted from the blade server will induce instability of the system.First, identify the fountainhead of the server noise with aeroacoustics knowledge and Experimental. Confirm the mostly noise is rotary noise and reckon the frequency. The CAD model of the blowers frame is made by the UG and then the simulation study for the air flow field of the blowers frame is made by the CFD program package FLUENT. Design an acoustic attenuation module through characteristic of the fountainhead of the server noise and word the conclusion of the simulation study. The effect is famous.In the end of the paper, another method is introduced to reduce the noise. Laying the fan reasonable can reduce the rotate speed with the system stabilization which make the noise lower.
