Introduction
Thermoelectric Assemblies (TEAs) are compact units that control the
temperature of a wide variety of applications, such as laser diode packages
in active optics, lasers in medical and industrial instrumentation, electronic
enclosures, sample storage chambers in medical diagnostics and analytical
instruments and batteries in various automotive and telecom applications.
TEAs serve a cooling capacity spectrum from approximately 10 to 400
Watts, and can cool by removing heat from control sources through
convection, conduction, or liquid means.
Advantages
TEAs offer several advantages over other cooling technologies. For
example, conventional fan trays do not cool to below ambient and
require an air exchange with the outside environment. On the other
hand, TEAs can cool to well below ambient and protect electronics
inside enclosures from outside contaminants, and also limit moisture
exposure from the outside environment. TEAs also offer precise
temperature control and accuracies to within 0.01˚C are achievable
under steady-state conditions.
TEAs have several advantages over conventional
compressor-based systems:
Compact size and lower weight than conventional
compressor-based systems
Mountable in any orientation and have lower noise and vibration
Environmentally friendly, as TEAs do not use CFCs and are RoHS
compliant
Low to no field maintenance requirement, which lowers the total cost
of ownership.
Engineers must now consider thermal management early in the product
design process. Simple thermal management solutions, such as adding
a fan or heat sink, are no longer typically viable to meet required
performance and reliability specifications.
A standard TEA allows the designer to start with a basic set of
building blocks that mate fans and TEMs to heat exchangers. Laird
has conducted two decades worth of design and validation testing
on various combinations of thermal components to optimize cooling
power and efficiency at various heat loads. This results in engineers
saving time with redesign and validation testing a TEA that has already
been perfected by Laird.
Below is a summary of inherent benefits of initiating a thermal design
with a standard TEA versus a custom solution:
1. Reduce product development time by initiated product at TEA level
vs TEM level.
2. Reduce costs by utilizing components that are already established
in the supply chain.
3. Long term history of products in field provide reliable field data
of robustness of products in operation.
4. Product enhancements are captured through market evolution.

TEA Portfolio
Laird offers the widest selection of TEAs on the market. Products are
designed and manufactured to strict process control standards and pass/
fail criteria, assuring that our customers receive the best possible TEAs.
Our standard product portfolio includes an extensive array of thermal
management solutions that cover a wide range of cooling capacities with
compact form factors and high coefficient of performance. Standard
operating voltages are 12 and 24 VDC, and on some models 48 VDC.
The standard product offering includes heat transfer mechanisms
designed to absorb and dissipate heat by convection, conduction, or
through liquid heat exchangers. All products are manufactured in an ISO
9001:2008 certified facility and are designed to meet the cooling needs
of many thermal management applications in the medical, analytical,
industrial and telecom markets.
There are five distinct TEA product families that were designed for a
specific cooling capacity range, temperature differential range or tight
space constraint. The diagram to the right is a perceptual map of a
cooling spectrum that can be used to guide designers to a particular
product family that will have the desired attributes that the application
requires.
Thermoelectric Applications
Thermoelectric Assemblies are used in a wide range of applications to
stabilize the temperature of sensitive electronic components or to cool
devices and compartments below ambient.
Telecommunications
Cooling below ambient is necessary to extend life of batteries
in wireless base stations. Temperature stabilization is required
to maintain peak performance of laser diodes.
Telecom Enclosures
Battery Backup Systems
High Powered Laser Diodes
Medical
Temperature stabilization is required to obtain a high image resolution.
Cooling reagent chambers below ambient is critical to extend life of
reagents and keep replacement costs down. Rapid thermal cycling is
crucial to speed up DNA amplification.

Air-to-Air Systems (AA)
Air-to-Air Assemblies offer dependable, compact performance
by cooling objects via convection. Heat is absorbed and dissipated
by heat exchangers equipped with fans and ducted shrouds.
Specifications apply to ambient temperature of 32°C and
nominal voltage with tolerances ±10%.
Power Cool Series
The Power Cool Series offers the widest selection of cooling capacities ranging from 20 to 193 Watts. The TEAs use impingement flow to
dissipate heat on the hot side. The cold side heat transfer mechanism can absorb heat using convection (heat sink and fan), conduction
(cold plate), or liquid (heat exchanger) means. This product series is offered in 12 or 24 VDC configurations. For 100 Watt systems and
higher, 48 VDC is available. The Power Cool Series is designed for indoor use in the medical, analytical, and industrial markets.

Liquid-to-Air Systems (LA)
Liquid-to-Air Assemblies cool or heat liquids that flow
through a heat exchanger. The liquid heat exchanger is
designed for a re-circulating system, absorbs heat and
pumps it through the TEM, where it dissipates into the
outside environment through an air heat exchanger.
Specifications apply to an ambient temperature of
32°C and nominal voltage with tolerances ±10%.
Tunnel Series
The Tunnel Series TEAs are designed with a patented,
high-performance cross flow technology that maximizes
heat transfer when pulling air through a heat exchanger.
The number of airflow paths required to operate is reduced
when compared to traditional impingement flow TEAs.
This product series is offered in 12 or 24 volt configurations
and can cool by either convection or conduction means.

Cascade Series
The Cascade Series is a TEA that is specifically designed to reach
colder temperatures than standard TEA product offerings. The
TEMs are custom designed multistage cascades that achieve a
high cooling capacity (Qc) at high temperature differentials (ΔT).
The cold side mechanism can transfer heat using convective (sink
and fan) or conductive (cold plate) means. This product series is
offered in 12 or 24 volt configurations and is designed for indoor
use in lab instruments.
Outdoor Cooler Series
The Outdoor Cooler Series is designed for outdoor use to control the
temperature of electronic cabinets. The product series has been designed to
pass harsh environmental demands such as earthquake resistance, salt fog,
wind-driven rain, high temperature exposure and dust. The cooling capacity
ranges from 100 to 250 Watts. This product series is offered in 24 and 48 VDC
configurations and is designed for outdoor use in the telecom and industrial
markets. As a standard option products are also sold with bi-polar thermostatic
control to heat and cool to specific temperature set points.

MRC Series Recirculating
Thermoelectric Chillers
MRC Chillers are self contained re-circulating chillers
that offer dependable, compact performance by
controlling the temperature of a coolant in a liquid
circuit. The coolant is re-circulated using a pump
with high mean time between failures (MTBF). Heat
from the coolant is absorbed by a heat exchanger
and dissipated through high density heat sinks
equipped with brand name fans. The TEMs are
custom designed to achieve long life operation.
The unit is regulated with an easy-to-use digital
temperature controller and is housed inside an
aesthetic sheet metal casing.
Direct-to-Liquid Systems (DL)
Direct-to-Liquid Assemblies cool or heat objects attached directly to the cold
plate. Heat is dissipated into a liquid heat exchanger on the hot side. The liquid
circuit is normally a re-circulating type that requires a pump and additional liquid
heat exchanger that dissipates heat into the ambient environment. Specifications
apply to the warm side liquid temperature of 32°C and nominal voltage with
tolerances ±10%.
