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 CoolingIf 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 CoolingIf 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 CoolingA 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 CoolingYou 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 SourcesThe 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 SourcesOther 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 Foundry equipment Blast

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
beremoved (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 FDelta 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 LoadIInntteerrnnaall hheeaatt llooaadd 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 3.413EExxaammppllee:: The Watt-loss chart for the
GS3 Drives shows that aGS3-2020 AC drive has a Watt-loss of 750
watts.BTU per Hour = 750 watts x 3.413BTU per Hour = 2559
Heat Load TransferHHeeaatt llooaadd ttrraannssffeerr is 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 ExampleA NEMA 12 Hubbell Wiegmann N12302412
enclosure (30" high x 24" wide x 12" deep) contains a GS3-2020 AC
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 the
GS3-2020 and is found to be 750 watts, so P=750 watts
Delta T = Max. operating temperature for the GS3-2020 is 104F
Max. ambient air temperature of 95FDelta T = 9FCFM = (3.17 x 750
watts) / 9FCFM = 264Choose a Hubbell Wiegmann WPF60-115BK filter
fan kit thatprovides 295 CFM with exhaust kit WPFA50-60BK
Air Conditioner Selection ExampleA NEMA 12 Hubbell Wiegmann
N12302412 enclosure(30" high x 24" wide x 12" deep) contains a
GS3-4030 AC drive30 HP 460 volt) that has a maximum allowable
operating temperature 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 the
GS3-4030 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 (115F 104F)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.
Select a TA10-050-16-12 Stratus air conditioner.

Book 3 (14.1)
Enclosure Cooling Selecting a Heat Exchanger
Heat exchanger selection To select the proper size heat
exchanger, the worst-case condi-tions should be considered. For a
heat exchanger to work, theambient air temperature must be lower
than the desired internalenclosure air temperature.
There are three main factors in choosing a heat exchanger foran
uninsulated metal NEMA rated enclosure located indoors:
Internal heat load Delta T Heat load transfer
Internal Heat LoadInternal 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
equipment installed in the cabinet. This is typically given
inWatts.
Delta T (T)Delta T = maximum allowable internal enclosure
temperature F maximum outside ambient temperature F.
Heat Load TransferHeat load transfer is 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 formulas:
Surface Area (sq. ft.) = 2 [(H x W) + (H x D) + (W x D)] /
(144sq. inches/sq. ft.)
Note: Only include exposed surfaces of enclosue in
calcula-tions. Exclude surfaces such as a surface mounted to a
wall.
Heat Load Transfer (W/F) = 0.22 W/F sq. ft. x surface area
Note: Use 0.22 Watts/F sq. ft. for painted steel and
non-metallic enclosures. Use .10 Watts/F sq. ft. for stainless
steeland bare aluminum enclosures.
Cooling CapacityOnce you have determined your Internal Heat
Load, the HeatLoad Transfer and the Delta T, you can choose the
proper sizeunit by calculating the needed cooling capacity.
Cooling Capacity (W/F) = Internal Heat Load / T - Heat
LoadTransfer
Heat Exchanger Selection ExampleA NEMA 12 Hubbell Wiegmann
N12302412 enclosure (30"high x 24" wide x 12" deep) contains a
GS3-4010 AC drive 10HP 460 volt) that has a maximum allowable
operating tempera-ture of 104F and is located in a warehouse that
has a maximumoutside ambient air temperature of 90F.
Power to be dissipated is stated in the specifications of the
GS3-4010 and is found to be 345 watts.
Internal heat load:Internal Heat Load = 345 Watts
Delta T:T (F) 104F 90F = 14F
Heat load transfer:
Surface Area (ft.2) = 2 [(30 x 24) + (30 x 12) + (24 x 12)] /
144 sq. inches= 19 ft.2
Heat Load Transfer = 0.22 x 19 ft2 = 4.2 Watts/F
Cooling capacity:Cooling Capacity = 345 Watts/14F - 4.2 Watts/F
= 20.4 Watts/F
In this example, you are able to determine that a Stratus
heatexchanger, with a capacity of at least 20.4 Watts/F is
needed,such as a TE30-030-17-04.
*This selection procedure applies to metal and non-metal,
unin-sulated, sealed enclosures in indoor locations. This
selectionprocedure gives the minimum required size; be careful not
toundersize when purchasing.

outside.
Construction Heat pipe technology Closed loop design
Listings UL File: SA34086 Made in USA
Features All units are available in NEMA Type 4 and4X

UL/cUL listed
The Air to Air Heat Exchanger is a closed loopcooling system
which employs the heat pipe prin-ciple to exchange heat from an
electrical enclosureto the outside. Where ambient temperatures are
suit-able for heat pipes, they are the most efficientmethod of
cooling as the waste heat is the enginewhich drives the system. The
only power requirementis to operate two circulating fans or
blowers.
Heat pipes have a liquid refrigerant under a partialvacuum
inside sealed tubes. They operate with aphase change process which
is much like that ofmechanical air conditioning, but without
thecompressor. Each heat pipe has an evaporatorsection and a
condenser section which are sepa-rated by a permanent baffle so as
to provide aclosed loop. The bottom of each heat pipe is incontact
with heated air from the electrical enclosure.When the enclosure
air reaches approximately 75degrees F., the refrigerant changes to
vapor phase(boils) and the vapor (steam) rises to the top of
thetube which is in contact with cooler outside (ambient)air.
When the outside air temperature is lower than the enclosure
temperature, the refrigerant vapor gives up heat to the outside air
andreturns to the liquid phase. It then falls to the bottom and
repeats the cycle endlessly so long as there is a negative
temperature differ-ential between the enclosure and outside. Heat
pipes will not operate in reverse cycle so heat cannot be
transferred from the ambientto the interior of the enclosure.
Although the operation is self limiting, thermostatic control can
be used to shut off the fans when notneeded.
The Stratus design has a top-to-bottom enclosure air flow
pattern with maximum separation of the inlet and outlet. This
design pullsthe hottest air from the top of the enclosure and
returns the cooled air from the bottom of the heat pipe to the
enclosure. The air flowon the ambient side is bottom in, top out,
so that the hotter discharge air moves up and away rather than
being recirculated.
The units use aluminum end plates and baffles which improve
conduction and reduce corrosion for longer life. The center
aluminumbaffle, which is swaged into the heat pipe coil, provides
an air tight seal between the two air systems.

ApplicationsFilter fans provide anoptimum climate in
enclo-sures. The interior tempera-ture of enclosures isreduced by
channelingcooler filtered outside airinto the enclosure,
thusexpelling heated internalair. The resulting air flowprevents
formation of local-
ized heat pockets and protects electronic components from
over-heating.
Outdoor filter fans are used in outdoor enclosures where warmair
must be dissipated. To clean and exchange the filter mat, youopen
the lockable door of the outdoor hood, eliminating theneed to allow
interior access to the enclosure. IP55 protectiontype is achieved
due to the special design of the hood and theuse of fine filter
mats.

How vortex coolerscreate 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. Theremaining 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.
