System Cooling of Outdoor Wi-Fi Antenna
Selectron investigated the cooling strategy for an outdoor Wi-Fi antenna, considering thermoelectric cooling, a convention vapour compression refrigeration unit, phase-change materials and an air-to-air heat exchanger from a cost vs. performance standpoint. The air-to-air heat exchanger was found to be best suited to this application and a FloTHERM model was built to predict the performance of this cooling arrangement. Violations against specified temperature limits were checked and remedial action taken by increasing vent openings, adding an internal fan. The work demonstrated that sealed outdoor enclosures can be cooled effectively with low cost air-to-air heat exchangers
