A Brief Introduction to
Thermoelectrics
Solid state heat pumps have been in existence since the discovery of
the Peltier effect in 1834. The devices became commercially available
several decades ago with the development of advanced semiconductor
thermocouple materials in combination with ceramics substrates.
Thermoelectric modules (TEMs) are solid-state heat pumps that require
a heat exchanger to dissipate heat utilizing the Peltier Effect. During
operation, DC current flows through the TEM to create heat transfer
and a temperature differential across the ceramic substrates, causing
one side of the TEM to be cold, while the other side is hot. A standard
single-stage TEM can achieve temperature differentials of up to 70°C.
A typical TEM’s geometric footprint can vary from 2 x 2 mm’s to 62 x
62 mm’s and are light in weight. This makes thermoelectrics ideal for
applications with tight geometric space constraints and low weight
requirements when compared too much larger cooling technologies,
such as conventional compressor-based systems. TEMs can also be
used as a power generator to convert waste heat into usable output
DC power.
Thermoelectrics are ideal for applications that require active cooling
to below ambient and have cooling capacity requirements < 600
Watts. A design engineer should consider TEMs when the system
design criteria includes such factors as precise temperature control,
high reliability, compact geometry constraints, low weight and
environmental friendly requirements.
Benefits of Using
Thermoelectrics
TEMs have several advantages over alternate cooling technologies:

• TEMs can cool devices down to well below ambient. Colder
temperatures can be achieved, down to minus 100°C, by using

• Devices are environmentally friendly because they use no CFC’s
and electrical noise is minimal.
• TEMs can be used as energy harvesters, turning waste heat into
usable output DC power.

Thermoelectric Product Line
Laird designs and manufactures thermoelectric modules (TEMs)
which adhere to strict process control standards and pass/fail
criteria, assuring our customers receive the best possible modules.
Our extensive standard product portfolio covers a wide range
of cooling capacities, temperature differentials, input power
requirements and geometric footprints. Standard finishing options
are available to accommodate alternate lead lengths, lapping
thickness tolerances, and moisture protective sealants. Standard
pre-tinning and solder constructions are available to accommodate
solder-able mounting of the TEM to the heat exchanger, or
processing of TEM through a reflow oven to solder onto an
optoelectronic package.
Laird offers several thermoelectric module product families that
can be classified by cooling capacity, temperature differential, form
factor or thermal cycling capability. Reference perceptual map as a
general guide as to where each product family fits with regards to these attributes.
Telecommunications
Optical components are used in backhaul communications to transmit data. Temperature stabilization of these devices is required to maintain
peak performance while ambient environment conditions fluctuate over time. Compact form factors are required to keep package size down
as well as no outgassing of thermal component.
Medical
Reagents are used in medical diagnostics to help analyze liquid samples obtained from patients to diagnose an illness. TEMs refrigerate the
reagents to extend their life and keep costs down. Molecular diagnostics use TEMs to thermal cycle DNA samples to create millions of strands
of DNA for analysis. Medical lasers use TEMs to keep temperature of laser stable and for patient comfort during treatment.
Industrial & Instrumentation
Operating IR detectors and CCD’s at low temperatures limits the noise they are exposed too. This expands the light spectrum they are able
to capture and increase resolution. Industrial lasers and metrology instrumentation use TEMs for temperature stabilization to maintain peak
performance. Digital printers use TEMs to control the humidity and optimize the ink drying process in high volume production runs.
Transportation
Advancements in transportation technology require continued innovations in thermal management solutions. For example, use of smart lighting
headlamps or industrial x-ray inspection systems, provide numerous benefits, however at increased temperatures that the devices must endure.
Active cooling mechanisms that feature the use of TEMs provide the thermal management solutions needed to operate each device within an
acceptable temperature range that optimizes its performance.
TEM Rapid Prototyping Center
Since there are so many unique attributes that need to be ascertained for each application,
often a customized TEM will yield a more optimal thermal solution. Laird offers strong
engineering services with a global presence that supports onsite concept generation,
thermal modeling, thermal design and rapid prototyping. We also offer validation test services to meet unique compliance standards for each
industry, such as Telcordia,
MIL-STDs or standards specific to unique application. Minimum order quantity (MOQ) applies for all custom TEM designs and validation testing.

Thermal Wizard
The Thermal Wizard is an online tool that allows engineers
to specify a given set of input variables based on application
attributes and model the performance of the TEM prior to
trial. The tool contains several application examples and an
active datasheet that simulates how the TEM(s) will function
under a specific set of operating conditions. Available only
online, the Thermal Wizard is accessible from the Laird
website at lairdtech.com/thermal-wizard.

Silicone (RTV) is an all purpose sealant that exhibits good sealing characteristics and retains its elastomeric properties over a wide temperature range,
-60 to 200°C.
The sealant is non-corrosive to many chemicals and exhibits good electrical properties with low thermal conductivity.
Epoxy (EP) is an effective barrier to moisture that exhibits a useable temperature range of -40 to 130°C. When cured the material is completely uni-cellular and therefore the moisture
absorption is negligible. The material exhibits a low dielectric constant, low coefficient of thermal expansion and low shrinkage.
