Calculation Corner: A Simple Method for Estimating Radiation Heat Transfer
This article describes a semi-empirical equation that can be used to assess radiation heat transfer in terms of an effective convection coefficient. The effective convection coefficient due to radiation is shown to be: Where temperatures are in °C and ε is the emissivity of the radiating surface. This equation is accurate to within ~10% over a temperature range of 0 - … [Read more...]
The Effect of Ambient Conditions on Local Climate Inside a Pump Electronics Enclosure
By: Parizad Shojaee Nasirabadi, Jesper H. Hattel INTRODUCTION Condensation and moisture related problems are the cause of failures in many cases and consequently serious concerns for reliability in electronics industry. Therefore, it is important to control the moisture content and the relative humidity (RH) inside electronics enclosures. Understanding the transport … [Read more...]
