Staying Cool: Increasing the Lifespan of Your Electrical Components

Warm temperatures can wreak havoc on electrical components and other manufacturing machinery. Heat may cause system failure, thermal aging and reduction in thermo-mechanical cycle life. To prevent catastrophic equipment failure, it is important to be familiar with potential issues and solutions. By putting these solutions in place proactively, facilities can insure that equipment failures and other negative effects are minimized or even eliminated. There are many systems and solutions available for proactively reducing the effects of extreme heat in enclosures.

Enclosure Air Conditioners: Designed to work directly inside an enclosure, air conditioners can be installed in various positions depending upon need and space. They are environmentally friendly as well.

Enclosure Water to Air or Air to Air Heat Exchangers: These specialized cooling systems convert hot air to cool air or utilize water to convert hot air to cooler temperatures. These unique units operate effectively when mounted in any position. The units use a closed-loop system that makes them an ideal choice for use in dirty environments.

Ventilation Systems: There are a large variety of blowers and fans designed to help clear out or circulate air to cool down an enclosure. These systems are designed to provide airflow in various applications. They are easy to install, and operate with equal effectiveness in any mounting position.

Condensation Reduction Systems: When condensation accumulates on the interior surface of an electrical enclosure, the chances of damage or failure become considerably higher. Internal heating systems or light bulbs can help reduce some moisture but has to be balanced so as not to damage the electronics with unnecessary heat. Moisture can be removed through the use of a dehumidifying system which can also help with condensation. The bottom line is that moisture exists and has to be managed in some way so equipment is not damaged.

Another way to stay cooler is with a higher performing spot cooler (aka 'CPU cooler').

Our CPU cooler shifts almost 6 Watts per degree C of temp rise. The next best (standard, i.e. non exotic, no peltier element or heat pipe / cold plate, etc, cooler) shifts just over 2 Watts per degree. Our design can be scaled up or down, will always provide the best cooling for its' size. Can be used for as small as tablets, up to industrial computers; for cooling competition automotive differentials, also in EVs for cooling power supply & controller, possibly also motors.

100 W cooling with only 16.7°C rise! 1/2 HP cooling with only 62°C rise!

Better performance anticipated with e.g. larger sizes, fluids / thermo optimisation, & or more exotic materials.

Design is available for licence. Can be in production within 6 months.

Principals only. No patent attorneys.

Cabinet coolers that utilize compressed air and vortex tubes are a good option in various applications. We used them in a welding control application that was housed in a large electrical enclosure.
