Abstract [en]

The Veo+ projector is using a cooling system that consists of fan and blowers. This system is

cooling the electronic components of the device and the lamp of the projector, however

extracting a high noise. To lower this noise the rpm speeds (rotational speed) of the fan and

blowers should be decreased. Thus, lowering the speed will result in higher temperature

values in whole system (inside the device). While lowering the speed, the higher temperature

values should be kept within the thermal design specifications of the electronic components.

The purpose of this thesis work is to find an optimal solution with lower rpm speeds of the

fan and blowers while keeping the temperatures of the various components of the device

(touch temperature of the enclosure and electronic components) within the temperature

design limits. Before testing the device to find the optimum state, the design limits of the

device are determined. Then, by using the design of experiment methods like Taguchi, the

optimum state for the device within the design specifications is obtained. Finally, additional

tests are applied within the optimum state to demonstrate a fan algorithm as a final solution.

While doing the experiments thermocouples are used for measuring the component

temperatures.
