Hard drives crash because of too high Fibrationen of the fan of Amsterdam, October 29, 2009 specifically for the market of 19-inch rack computers with one rack space (1U) Delta Electronics Introduces now fan, that address three typical problem districts of modern Hochleistungsboards: airflow, vibration and energy consumption. To bring no thermal collapse of rack PCs, whose fans had to walk so far in full swing. -Harmful especially for hard drives – vibrations were correspondingly high. The new Delta fan vibrate less when compared to conventional fan designs in the main speed ranges up to 40 to 50 percent. This is achieved comparable to a car wheel by a balancing of the propeller on the outside as well as inside. Normal fans are only centrally balanced and therefore more prone to vibrations.
Offers the standard fan FFB40x40x28 will be in dimensions 40 x 40 x 28 mm (width x height x depth). For thermally challenging computer there GFB40x40x48 and GFB40x40x56 a fan solution with two cascaded, contra-rotating, and separated by a stator propeller units. The stator behaves like the spoiler on a race car: he smoothes the where air coming out of the first fan and targeted leads them into the second fan. Thus increases is opposite in a row mount the entire pressure and air flow rate and hence the efficiency of ordinary fans significantly. Low rack temperature can be reduced the numbers of revolutions of the two propeller without having the air flow falls below a critical limit. Thus once again reduce the vibration and noise. Alternatively also one of propeller units can be designed redundantly: the first propeller fails, the other assumes its function automatically. The new fan Delta Electronics now in the relevant specialist are available.
