Excessive heatcan cause nuisance faults from your electrical and electronic components: for example, overloads tripping unexpectedly. Heat will also changethe expected performance of circuit breakers and fuses, which can cause whole systems to shut down unexpectedly. So, if you have any electronicequipment or other heat sensitive devices, you may need cooling.What causes all that heat?There are basically two sources that can cause the enclosure’s internal temperature to rise above the ratings of the control equipment.Internal SourcesExternal SourcesThe same items that can be damaged by heat may alsobe the source of the heat. These include items such as: Power supplies Servos AC Drives/inverters Soft starters Transformers PLC systems Communication products HMI systems Battery back-up systemsOther sources of heat that can cause the internaltemperature of your enclosure to rise above a desiredlevel involve the external environment. These includeitems such as: Industrial ovens Solar heat gain Foundry equipment Blast furnacesGet the heat outHow do you get the heat out of your enclosure and away from those critical components?There are several basic cooling methods available, depending on the coolingrequirements and the enclosure environment.Radiation and Natural Convection CoolingNatural Convection CoolingHOTIf the ambient temperature outside the enclosure is cooler than the inside of the enclosure,some heat will be radiated into the atmosphere from the surface of the enclosure. Inenvironments where dust and water intrusion is not a concern, louvers can be added toallow outside air to flow through the enclosure via natural convection - the movementof air due to it's expansion (reduced density) when it's heated and contraction (increaseddensity) when it cools.On a large scale, natural convection can be a powerful force - it's one of the primarydrivers of our weather. But on the scale of an electrical enclosure, its cooling capacityis very limited. For larger heat loads, a more powerful cooling system may be needed.Since they create openings in the enclosure, louvers are typically limited to NEMA 1 and/or NEMA 3R applications. However, some louvers have optional filters that can be addedto maintain NEMA 12 protection.Forced Convection CoolingHOTForced Convection CoolingThe next step up from natural convection is forced convection cooling. The basiccooling mechanism is the same: cooler air from outside the enclosure passes throughthe enclosure to remove the heat. The difference is that the air is mechanically forcedthrough the enclosure by a filter fan. The fan produces higher air flow rates than naturalconvection, which in turn increases the amount of heat removed.As with natural convection cooling, the ambient air temperature must be lower than thedesired enclosure temperature for forced convection to be effective.COLDHOTA typical forced convection system consists of a fan and a grille, with a filter on the intakedevice and either a filter or louvers on the exhaust device. The filters and louvers allowthe enclosure to maintain NEMA 12 protection. In NEMA 4 or NEMA 4X environments,hoods can be added to both the fan and the grille to prevent the ingress of water.www.automationdirect.comEnclosures Thermal ManagementtENC-368

Heatexchangers and air conditioners are both closed loop cooling systems. The primarydifference in the two is the refrigeration system.The refrigeration system in a heat exchanger is a set of sealed tubes of alcohol. Heatabsorbed from the internal enclosure air boils the liquid alcohol at the bottom of the tube,causing it to rise to the top. The heat is then rejected to the cooler ambient air stream,causing the alcohol to condense back to a liquid and fall to the bottom.Air Conditioners & Heat ExchangersCOLDHOTHeat exchangers are very efficient because the refrigeration system has no moving parts- the only moving parts are the two fans. But for the heat to transfer through the system,the ambient air must be colder than the air inside the enclosure, just as it must be forfilter fans.Enclosure air conditioners function in the same manner as a residential or automotiveair conditioner, with refrigeration loop powered by a compressor. The refrigerant absorbsheat from the internal air at the evaporator coil and rejects it to the ambient air at thecondenser coil. Unlike heat exchangers, they can provide cooling even if the ambienttemperature is higher than the enclosure temperature. They can also be scaled to handlelarger heat loads than any other cooling system.Enclosure air conditioners are available for NEMA 12, NEMA 4 and NEMA 4Xapplications.Vortex CoolersVortex coolers create a stream of extremely cold air from a supply of filtered compressedair. The cold air is injected into the enclosure, displacing warm air which is exhaustedback through the vortex cooler. While not a closed-loop system, they can be used in thesame harsh environments since the cold air injected into the enclosure is filtered air froma compressed air system, not ambient air. Vortex coolers can also be used where theambient temperature is higher than the enclosure temperature.Vortex CoolingCompressedAir InInternalAir OutRelief Valves toVent Hot AirInternalAir InSolenoidValveFilter/RegulatorInternalAir InCold EndMufflerSince vortex coolers prevent the ingress of ambient air or sprayed water and are madefrom corrosion-resistant materials, they can be used on NEMA 4X enclosures in harsh,wash-down, and/or corrosive environments.AdjustableThermostatClean ColdAir InsideVortex coolers are commonly used in lieu of a small or medium enclosure air conditionerin applications where there isn’t adequate space to mount an air conditioner, providedthere is an adequate supply of compressed air.Thermoelectric CoolersAnother alternative to a conventional air conditioner is a thermoelectric cooler, whichis sometimes referred to as a Peltier cooler. They function in a manner similar to an airconditioner or heat exchanger, with fans inside and outside the enclosure, but with athermoelectric unit replacing the fluid-based refrigeration system.The thermoelectric units consist of an array of semiconductors sandwiched between twoceramic plates. When a DC current is applied to the semiconductor array, heat is drivenfrom one plate to the other, creating a cold side and a warm side. This is known as thePeltier Effect. Fans circulate air across each of the plates, allowing the cold plate toabsorb heat from the enclosure and the warm plate to reject it to the ambient air.Like vortex coolers, thermoelectric coolers can be used with NEMA 4X enclosures inharsh, wash-down, and corrosive environments, and where the ambient temperatureexceeds the enclosure temperature.Thermoelectric CoolingAmbientAir OutInternalAir OutInternalAir InAmbientAir InInternalAir OutAmbientAir OutThermoelectric coolers are an alternative to air conditioners in small cooling capacityapplications where there isn’t adequate space for an air conditioner.www.automationdirect.comEnclosures Thermal ManagementtENC-369

This can be determined by a few different methods.The preferred method is to add the maximum heat outputspecifications that the manufacturers list for all the equipmentinstalled in the cabinet. This is typically given in Watts, so use thefollowing conversion:BTU per Hour Watts x 3.413Choose a Stego 018740-30 230VAC FPI filter fan with a118740-00 exhaust grille to provide 220 CFM or a Stego018840-00 230VAC FPO filter fan with a 118840-30 intake grilleto provide 243 CFM.Air Conditioner Device Selection ExampleANEMA12WiegmannN12302412enclosure(30” high x 24” wide x 12” deep) contains a GS3-4030 ACdrive 30 HP 460 volt) that has a maximum allowable operatingtemperature of 104 F and is located in a warehouse that has amaximum outside ambient air temperature of 115 F.Power to be dissipated is stated in the specifications of theGS3-4030 and is found to be 1290 watts.Internal heat load:BTU per Hour 1290 watts x 3.413BTU per Hour 4403 BTU/HHeat load transfer:Heat load transfer (BTU/H) 1.25 x 19 sq. ft. x (115 F – 104 F)Heat load transfer (BTU/H) 261.25 BTU/HCooling capacity:Cooling capacity (BTU/H) 4403 BTU/H 261.25 BTU/HCooling capacity (BTU/H) 4664.25 BTU/HIn this example, you are able to determine that a 5000 BTU/Hunit is needed.

A typical forced convection system consists of a fan and a grille, with a filter on the intake device and either a filter or louvers on the exhaust device. The filters and louvers allow the enclosure to maintain NEMA 12 protection. In NEMA 4 or NEMA 4X environments, hoods can be added to both the fan and the grille to prevent the ingress of water.
