I need help regarding a small project on thermoelectric refrigerator. I need to cool a 5.4 ltr capacity refrigerating space to maintain it at 10-12 degrees. I have the cooling module in place.I needed to dissipate 98 W of power from one module via a heat sink. I have a heat sink that is of pin type measuring 96*96 mm with 98 pins of rectangular cross section.I need to find: a) The thermal resistance of this heat sink when coupled with a cooling fan of 12.5W b)how to choose a heat sink so that the temperature rise can be restricted to 20 degrees from the ambient temperature. anyone having any idea in this topic please reply!!!
