|Advances in Telecommunications Thermal Management Solutions|
|Keywords: Plastic Technology, Thermal Efficiency, Energy Savings|
|The focus of this paper is to discuss Thermal Management Solutions that are used to cool Telecommunications Equipment. New products using advances in plastics give increased performance with broader applications. Combining different technologies into new single solutions give better performance with lower energy costs. Air Conditioners and Heat Exchangers have commonly been used in the Telecommunication industry to provide above and below ambient cooling for electronic cabinets and shelters. These solutions are good alternatives to the direct air cooling methods that can allow dust, dirt, and humidity to contaminate the enclosure. Air conditioners in the range of 500 watts to 28 kilowatts are readily available. These units often have advanced features such as alarm failure signals, Laptop communication, and independent heating / cooling set points. Air to Air Heat exchangers have the advantage of using very little power and removing heat at various rates up to and exceeding 300 W/K. Advances in heat exchanger technology are making them more appealing with the use of plastics to reduce weight, reduce noise, and provide higher thermal efficiency. Unfortunately, heat exchangers are still at a disadvantage in that they cannot provide below ambient cooling. As energy costs continue to climb, the need for more economical solutions increases. The high power consumption of air conditioners is well known. However, combining Heat Exchangers and Air Conditioners into a single package unit allows for an economical cooling solution. Heat Exchangers provide sufficient cooling to meet the heat loads when the ambient temperature is below the room temperature. The air conditioner only needs to operate when the ambient temperature is above the desired room temperature. The combination unit will typically have a power bill less than half of a comparable air conditioner.|
