1. The problem statement, all variables and given/known data An electronic chip of 5cm x 5cm surface is to be cooled by a water cooling method (see drawing) 2. Relevant equations If 500W of heat is to be removed from the chip, what is the temperature of water from the time of operation until 5 hours if the fan is not operational (assuming the water quantity is 20 liters, and initial temperature is 15°C). (Plot temperature vs time) (water flows 50 cc/s). 3. The attempt at a solution If you turn on the fan of 12 cm in diameter with 100 cfm flow, what do you expect the temperature will be in the next one hour (plot temperature vs time in every 5 minutes) (assuming the air temperature is 15°C). What do you expect the die temperature for the above two cases (fan on and off)? Plot temperature vs time. The Chip has a die initial temperature of 100°C.
