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.

COOLING SYSTEM FOR MICRO-CELL COMMUNICATION EQUIPMENT BASED ON CONSTANT LOSS COOLING FLUID

by James Gehrke

BACKGROUND:

  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.

PRINCIPLE OF OPERATION:

  The invention solves many problems with the cooling of micro cell communication equipment. The electronic micro cell equipment needs to be as com- pact and light as possible for the desired pole or wall mount installations. These problems are solved by using a constant loss cooling fluid that consists of processed atmosphere (compressed air). This cooling fluid is processed externally from the com-

munication equipment removing dust and water vapor and heat through compression.

  The proposed approach eliminates all prior prob- lems by using a air compressor system in an easy serviceable location to filter, compress, and dehu-...
