Resumo

The results of the heat-exchange and aerodynamic pressure drop experimental investigation of several years' standing (1961-1968) are presented. Tests were carried out with pin-fin surfaces in the air flow, the pins being disposed in line. The investigations are fulfilled conformably to a thermoelement construction of a thermoelectric semiconductor heat pump. The pin diameter (d) was varied from 0.6 to 1.3 mm the pin length (1) - from 5 to 89 mm (providing d = 1.3 mm), the relative transversal and longitudinal spacings - correspondingly from 1.21 to 4.36 and from 1.31 to 5.06, and Reynolds' number - from 200 to 1900.
