Delta Electronics, provider of power management and thermal management solutions, announced its new power system cooling solutions for OutD outdoor power systems that provide significant reductions in CO₂ emissions and offer energy and cost savings.

“A battery compartment requires more effective cooling, whereas telecom devices and rectifiers can withstand much higher temperatures. Delta offers active cooling devices TEC for effective battery cooling. The rest of the system receives an optimized operating temperature through air conditioning, air ventilation or heat exchangers, or any combination of these,” commented Andrzej Chaberek, outdoor product manager of the Telecom Power Solutions Business Unit for Delta Electronics, in a press release.

“Using our hybrid cooling solutions, the savings in cooling can rise up to 90 percent. This revolutionizes the cost structure of thermal management and can achieve more than 40 percent savings in a site’s total energy consumption. By deploying Delta’s hybrid cooling and TEC solutions on a minimum of 1000 sites, an operator’s annual savings could reach one million euros,” continued Chaberek.

Cooling plays a critical role in site energy consumption: it requires roughly as much energy as the actual telecom equipment. The advanced climate management features of Delta’s OutD solutions reduce the amount of energy needed for cooling by up to 80 percent.

The company’s new OutD solution features a separate battery cabinet, which is cooled more effectively than the rest of the cabinet, using thermoelectric cooling. While other system equipment may function perfectly at much higher temperatures, battery cooling is extremely important, because a 10 degrees Celsius rise in temperature in the battery cabinet halves the lifetime of a battery. We use energy for cooling only when necessary.

The advanced monitoring unit gathers data using independent temperature sensors, also registering fan and heater operation. In addition, the units allow detailed control over fans and ventilation. The monitoring system can be controlled and configured to exact specifications remotely using a laptop without the environmental burden caused by travel to the site.

Telecom power systems secure telecommunication services in case of power interruptions or fluctuations. The essential parts of the system are rectifiers, batteries and a power system controller. The rectifier converts alternating current (AC) to direct current (DC) and provides the power necessary to charge the batteries.
