Abstract
In a thermo-electric refrigerator, fin array for heat transmission must be of small dimensions and have high over-all heat transfer coefficient. Fora compact parallel fin array, approximate calculations of heat transfer coefficient are made for free convection and forced convection at a relatively low air flow rate of 50_??_300cm/sec. These values are compared with masured values, and heat transfer coefficient and optimum fin spacing are established in each case.
