Abstract

Thermal management is a serious concern in electronic industry. It is important to understand the effects of ambient conditions on cooling of electronics. In this work, the effect of ambient conditions on the thermophysical properties of humid air is estimated in five cities (Copenhagen, Mashhad, Singapore, Las Vegas and Jakarta). Thereafter, the Nu number is calculated for cooling of an isothermal surface in horizontal and vertical orientations. Comparing the results, shows that Pr number is very slightly affected by ambient conditions; however, Gr is following the temperature changes. Among the investigated cities Singapore and Jakarta, the cities with the higher temperature and moisture concentration had the lowest heat transfer coefficients.
