Abstract

In modern communication systems it is very desirable to design compact base transmiter site equipment. Some base transmission sites have the equipment in an environmentally shielded housing that sits at the base of the antenna. Also there exist micro cell transmitters that are compact and light enough they can be mounted on a pole or wall. One major problem with these compact transmitter sites is the removal ofwaste heat.

COOLING SYSTEM FOR COMMUNICATION EQUIPMENT CABINEB

USING AN ACTIVE VENTILATION SYSTEM DESIGNED TO PREVENT MOISTURE CONDENSATION

by James K Gehrke and William Morrison

BACKGROUND:

  In modern communication systems it is very desirable to design compact base transmiter site equipment. Some base transmission sites have the equipment in an environmentally shielded housing that sits at the base of the antenna. Also there exist micro cell transmitters that are compact and light enough they can be mounted on a pole or wall. One major problem with these compact transmitter sites is the removal ofwaste heat.

increases the size and weight of the housing to a level that makes micro cell non-ground mounting impracticable.

  The much simpler forced air cooling produces the water vapor condensation problem when out- side air is forced through communication equipment that is at a lower temperature than outside air. If the cooler equipment surface temperature is below the dew point of the air being forced into the equip- ment water will collect on the cool surfaces. This water can produce great corrosion problems.

  Therefore there is a need for a simple commu- nication system transmitter site cooling system that will eliminate the condensation problems.

PRIOR ART:

  One of the least complex ways to eliminate heat buildup in the high density equipment's housing is to force cooling air through the enclosure. While this approach eliminates the complex and failure pr...
