  EXPERIMENTAL WORK TO MEASURE COOLING TEMPERATURE OFAN  ELECTRICAL UNIT WITH HEAT GENERATION              Prof. Dr. Adil. A. Alwan                                                                                  Rafel. H. Hameed             University of Babylon                                                                                 University of Babylon   Abstract          The satisfactory performance of electrical equipments depends on their operating temperature. In order to maintain these devices within the safe temperature limits, an effective cooling is needed. Cooling process of this equipment was important to save it from temperature rising, which are major causes of failure. Fan with constant low speed at one direction of air flow was used for cooling to measure the reducing of heating temperature through working of this equipment. Experimental work was done to measure the spatial and temporal distribution of temperatures profile at different locations of the sample, by using a computerized temperature meter (CTMO1). A rectangular box of brass alloy was used as a sample of electrical equipment. The heat transfer coefficient values were found at the side and top of equipment through both processes of cooling and heating. The experimental results were agree well for prediction results for two theoretical models in heating and cooling process with error percentage about 6% to 15% of Hameed, 2010.
