PP B Heat Stresses Electronics Sources of Damaging Heat Effects of Damaging Heat The Benefits of Cooling Cooling Solutions McLean Cooling Solutions Key Concepts Why Cool Electronics? The problem of heat, the benefits of cooling

PP B Heat Stresses Electronics Faster, more powerful devices produce more heat Higher density of electronic devices used in control applications Devices not hardened to environmental extremes Relationship between high performance & temperatures & reliability Customers seek insurance solutions to protect from costly shutdowns. advancing technology increased awareness of temperature vs. reliability Thermal Product Market Drivers

PP B Heat Stresses Electronics Every 10°C / 18°F rise over room temperature cuts electronic life expectancy in half

PP B Sources of Damaging Heat Heat can come from sources inside the cabinet... Indoor Industrial, Telecom & Data Networking AC power supply Controllers (PLCs) Drives & servos Transformers Radio equipment Battery back-up Server racks Processors Inverters Contactors & relays

PP B Sources of Damaging Heat... outside the cabinet... Indoor Industrial & Telecom Welding process Paint oven Solar heat gain Blast furnace Foundry equipment

PP B Sources of Damaging Heat... from the electronics themselves... More electronics going into same size or smaller enclosures Datacom, telecom demanding higher performance More server functions mean more heat

PP B Sources of Damaging Heat Semiconductor transistor density and performance double every months. Moores Law Named for Intel founder, Dr Gordon Moore... as performance increases...

PP B Sources of Damaging Heat... and from the surrounding environment Global economic growth is sparking installations in warmer climates Burj Al Arab Hotel Dubai, United Arab Emirates

PP B Effects of Damaging Heat At extreme temperatures... 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 B Effects of Damaging Heat What does it cost to shut down an automotive assembly line for 1 hour? Over $500,000

PP 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
