Get the heat outHow do you get the heat out of your enclosure and away fromthose critical components? There are three basic cooling methods.

Natural Convection Cooling

If the ambient temperature outside the enclosure is cooler than theinside of the enclosure, then the heat can be dissipated into theatmosphere by radiating it through the surface of the enclosureand through the use of louvers or grilles with filters.

Forced Convection Cooling

If you have clean and cool ambient air outside of the enclosure,

then a simple forced-air system may be adequate. A system suchas a filter fan and the associated grille with the appropriate filtermay be an acceptable option.

Closed Loop Cooling

A system that will keep the ambient air separate from the internalenclosure air is needed if the environment is harsh, there are wash-down requirements, heavy dust and debris or the presence ofairborne chemicals, and the ambient temperature is as high asor higher than the desired internal temperature. Air conditionersare an example of a closed loop system.

Enclosure Cooling

You need to cool downHeat inside an enclosure can decrease the life expectancy ofcontrolling units such as your PLC, HMI, AC drives and otheritems. Excessive heat can cause nuisance faults from your electricaland electronic components: for example, overloads tripping unex-

pectedly. Heat will also change the expected performance of circuitbreakers and fuses, which can cause whole systems to shut downunexpectedly. So, if you have any electronic equipment or otherheat sensitive devices, you may need cooling.

What causes all that heat?There are basically two sources that can cause the enclosuresinternal temperature to rise above the ratings of the control equip-ment.

Internal Sources

The same items that can be damaged by heat may also be thesource 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 systems

External Sources

Other sources of heat that can cause the internal temperature ofyour enclosure to rise above a desired level involve the externalenviroment. These include items such as:

Industrial ovens Solar heat gain

Enclosure Cooling Selecting a Fan or Air ConditionerFan selectionTo select the proper size (CFM) fan for your forced air coolingsolution, you need to determine the amount of heat to be

removed (in watts) and determine the Delta T (Max. allowableinternal enclosure temperature F Max. outside ambienttemperatureF).

CFM = Cubic Feet per MinuteP = Power to be dissipated in wattsCFM = (3.17 x Pwatts) / Delta T F

Delta T = max. allowable internal enclosure temperature F max.outside ambient temperature F

Air conditioner selectionTo select the proper size air conditioner, the worst-caseconditions should be considered, but take care not to choose anoversized unit.

There are two main factors in choosing an uninsulated metalNEMA rated enclosure located indoors:

Internal heat load

Heat load transfer

Internal Heat Load

Internal heat load is the heat generated by the componentsinside the enclosure. This can be determined by a few differentmethods. The preferred method is to add the maximum heatoutput specifications that the manufacturers list for all the equip-ment installed in the cabinet. This is typically given in Watts, souse the following conversion:

BTU per Hour = Watts x 3.413

Example: The Watt-loss chart for the GS3 Drives shows that aGS3-2020AC drive has a Watt-loss of 750 watts.

BTU per Hour = 750 watts x 3.413BTU per Hour = 2559

Heat Load Transfer

Heat load transferis the heat lost (negative heat load transfer) orgained (positive heat load transfer) through the enclosure wallswith the surrounding ambient air. This can be calculated by thefollowing formula:

Heat load transfer (BTU/H) = 1.25 x surface area (sq. ft. ) x (max. out-side ambient air (F) max. allowable internal enclosure temperatureair (F))Surface Area (sq. ft.) = 2 [(H x W) + (H x D) + (W x D)] / 144 sq. inches

Note: 1.25 is an industry standard constant for metal enclosures;0.62 should be used for plastic enclosures.

Once you have determined your Internal Heat Load and theHeat Load Transfer, you can choose the proper size unit bycalculating the needed cooling capacity.

Cooling capacity (BTU/H) = Internal Heat Load Heat Load Transfer

Fan Selection Example

A NEMA 12 Hubbell Wiegmann N12302412 enclosure(30" high x 24" wide x 12" deep) contains a GS3-2020AC drive

(20 HP 230 volt) that has a maximum allowable operatingtemperature of 104F and is located in a warehouse that has amaximum outside ambient air temperature of 95F.

Power to be dissipated is stated in the specifications of theGS3-2020and is found to be 750 watts, so P=750 watts

Delta T = Max. operating temperature for the GS3-2020 is104F Max. ambient air temperature of 95F

Delta T = 9FCFM = (3.17 x 750 watts) / 9FCFM = 264

Choose a Hubbell Wiegmann WPF60-115BK filter fan kit thatprovides 295 CFM with exhaust kit WPFA50-60BK

Air Conditioner Selection Example

A NEMA 12 Hubbell Wiegmann N12302412 enclosure(30" high x 24" wide x 12" deep) contains a GS3-4030AC drive30 HP 460 volt) that has a maximum allowable operatingtemperature of 104F and is located in a warehouse that has amaximum outside ambient air temperature of 115F.

Power to be dissipated is stated in the specifications of theGS3-4030and is found to be 1290 watts.

Internal heat load:

BTU per Hour = 1290 watts x 3.413BTU per Hour = 4403 BTU/H

Heat load transfer:

Heat load transfer (BTU/H) = 1.25 x 19 sq. ft. x (115F 104F)Heat load transfer (BTU/H) = 261.25 BTU/H

Cooling capacity:

Cooling capacity (BTU/H) = 4403 BTU/H + 261.25 BTU/HCooling capacity (BTU/H) = 4664.25 BTU/H

In this example, you are able to determine that a 5000 BTU/Hunit is needed. Select a TA10-050-16-12Stratus air conditioner.

Applications Compressed air cooling is used where

conventional enclosure cooling by

air conditioners or heat exchangers is not

possible(Example: Small to medium size

enclosures, nonmetallic enclosures, and

areas where the size of cooling devices is

restricted)

Features Suitable for harsh environments

Small physical size

Creates cool air without refrigerants

(no CFCs, HCFCs)

Exceptionally reliable - no moving parts

and virtually no maintenance

Requirements Uses clean, dry, oil-free compressed air

(100 PSIG / 70 degrees F or below)

required to achieve published BTU/hr

ratings. Lower pressures and higher

temperatures will reduce BTU/Hr ratings. A 5-micron water and particulate removal

filter must be installed prior to operating

any vortex cooler (included in kits).

An oil removal filter can be installed

between the 5 micron filter and the

Vortex Cooler if oil is present in the

compressed air line.

Mounting holes NEMA 12 kits: (1) 1-3/32 (28mm) or 3/4

knockout hole for cooling tube and (1)

11/16 hole for thermostat

NEMA 4 and 4X kits: (1) 1-15/16 (49mm)or 1-1/2 knockout hole for cooling tube

and (2) #8 holes for thermostat

How vortex coolers

create cold airVortex coolers are powered by a vortextube - a unique device that creates avortex from compressed air and separatesit into hot and cold airstreams. Hereshow it works: The vortex tubes cylindricalgenerator causes the input compressedair to rotate, reaching speeds up to1,000,000 rpm as it is forced down theinner walls of the hot longer end of thevortex tube. At the end of the hot tube, asmall portion of this air exits through aneedle valve as hot air exhaust. The

remaining air is forced back through thecenter of the incoming air stream at aslower speed. The heat in the slowermoving air is transferred to the fastermoving incoming air. This super-cooledair flows through the center of the gener-ator and exits through the cold air exhaustport.
