Demanding cooling for ground power units

Electronic cooling for aircraft ground power units: We have developed a cooling solution that meets the high demands placed on the electronics of power supply units on the airfield or in the hangar.

THE CHALLENGE

Aircraft are connected to a ground power unit (GPU) to supply power on the ground. This can significantly reduce the running times of the noise-, emission-, fuel- and maintenance-intensive auxiliary power units.

The manufacturer of a modular GPU system needed a cooling solution for the semiconductor frequency converters installed in it, which generate the required voltage of 270 V and 400 Hz. The solution had to meet high standards of efficiency, protection class, reliability and operating temperature.

THE SOLUTION

We developed a customized solution for two 92 mm fans and determined the optimum operating point in conjunction with the heat sinks installed in the device and the requirements for performance, protection class and temperature resistance. The intelligent control efficiently adjusts the fan speed to the cooling requirement – reliably at both +50 °C and –40 °C.

The inverter module is reliably kept at an optimal temperature. Improved air flow minimizes performance losses and increases efficiency. The solution seamlessly integrates into the customer’s modular system. The robust fans can permanently withstand even extreme conditions and, thanks to the well-thought-out design, the noise level remains below 65 dB.

The result: a reliable solution that the customer was able to integrate into its modular frequency inverters and that meets the strict criteria for use on the apron and in hangars.
