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

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

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

Sources of Damaging Heat
. . . outside the cabinet . . .
Indoor Industrial & Telecom
Welding process
Blast furnace
Paint oven
Foundry
Solar heat gain
equipment
PP-00089 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-00089 B
Sources of Damaging Heat
. . . as performance increases . . .
“Semiconductor transistor
density and performance
double every 18-24 months.”
Moore’s Law
Named for Intel founder,
Dr Gordon Moore

. . . and from the surrounding environment
Global economic growth
is sparking installations
in warmer climates

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

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

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
