Abstract

Micro-cell communication equipment requires light and compact base site equipment that can be mounted on a pole or wall. This microcell equip- ment is normally mounted with no extra environ- mental protection then its own cabinet. The ther- mal dissipation in these small units represents a major problem. Fan type forced air cooling has been shown to have reliability, dust contamination of circuits, air flow blockage and water vapor condensation prob- lems. Some designs use closed cooling system within a sealed housing to solve the dust and condensation problems but this approach adds greatly to size and weight. In addition it produces reliability and serv- ice problems.
