Unattended base stations require an intelligent cooling system because of the strain they are exposed to. The sensitive telecom equipment is operating 24/7 with continuous load that generates heat. Cooling systems must protect critical telecommunication cabinets, energy storage systems and back-up battery systems. Bulky compressor-based air conditioners have traditionally been used for removing heat generated by communications equipment installed in base station and cell tower enclosures. Thermoelectric assemblies (TEAs) offer a smaller, more efficient option to precisely cool or heat vital electronics in telecom enclosures, energy storage and battery backup cabinets.
