Catastrophic failures Properties of silicone materials change Drive performance is de-rated I/C based devices may experience intermittent fluctuations in output and voltage migration Mean Time Between Failure (MTBF) decreases exponentially PP-00089 B Effects of Damaging Heat What does it cost to shut down an automotive assembly line for 1 hour? Over $500,000 PP-00089 B Effects of Damaging Heat Consider the costs associated with the following . . . Productivity losses of plant/line shutdowns Labor Scrap Opportunity cost Component costs In warranty – processing costs, labor Out of warranty – out of pocket costs Material & Labor Customer satisfaction costs Missed ship dates PP-00089 B The Benefits of Cooling Cooling is essential to protect electronics & maintain performance Cooling electronics can: Extend operational life Instill smooth performance Maintain valuable equipment warranties Prevent catastrophic failure Maintain productivity Fans cooling server power supply unit PP-00089 B Cooling Solutions The good news: cooling options are readily available Basic Cooling Options: Air Conditioners Heat Exchangers Thermoelectric Coolers Air Movers — Fans/Blowers/Impellers Specialized Cooling Options: Water-Cooled Air Conditioners Vortex Compressed Air Coolers PP-00089 B Cooling Solutions Heat Removal Low Mod High Cools Below Ambient Closed-Loop* Controls Condensation Price Other Considerations Air Conditioners √ √ √ √ √ √ High Water-cooled solutions availble for harsh environments - requires a chilled water source. Thermelectric Coolers √ √ √ Moderate Heat Exchangers √ √ √ Moderate Fans & Blowers √ √ Vortex Coolers √ √ Low √ √ √ Moderate Use when A/C or thermoelectric cooler won't meet space requirements - requires compressed air source. *Closed Loop: Utllizes internal cabinet air to cool. Does not utilize ambient outside air to enter the cabinet (open loop). PP-00089 B Cooling Solutions Let our online selection tool help you find the right solution! 1.
