Custom Cooling Assemblies have compact. solid-state design.

Press Release Summary:

Cascade Series Thermoelectric Assemblies (TEAs) use multistage Thermoelectric Modules (TEMs) to achieve high temperature differential from ambient. Able to be located directly on actual devices requiring cooling, standard configurations include Air-Air (AA), which uses convection cooling, and Direct-Air (DA), which uses conduction cooling. At temperature differentials greater than 30°C from ambient, cooling capacity is near 60% of max cooling power.

Laird Technologies Releases Enhanced Cascade Series Thermoelectric Assemblies

New Thermoelectric Assemblies Achieve Higher Cooling Capacities at Colder Temperatures

St. Louis, Missouri, USA - Laird Technologies, Inc., a global leader in the design and supply of customized performance-critical components and systems for advanced electronics and wireless products, today announced the release of its enhanced Cascade Series Thermoelectric Assemblies (TEAs).

The Cascade Series TEAs are custom designed cooling assemblies that use multistage Thermoelectric Modules (TEMs) to achieve a high temperature differential from ambient. This product series can produce up to a 40% higher cooling capacity at cold temperatures, surpassing standard product offerings with similar form factors.

One of the key benefits of the Cascade Series TEA is its compact size, solid-state construction, and ability to be located directly onto the actual device requiring cooling. Direct placement of the TEA reduces the need in many low temperature applications to use a conventional compressor-based cooling system, which generally cannot be integrated into the end user's devices due to its size.

Two standard configurations, as well as custom configurations which require a Minimum Order Quantity (MOQ), are available. The standard configurations include:
  • Air-Air (AA) - Convection cooling method where heat is absorbed and dissipated by high-density heat exchangers equipped with air-ducted shrouds and fans. Products in this series include AAC-050-24-22-00-00.
  • Direct-Air (DA) - Conduction cooling method where heat is absorbed through a cold plate and dissipated by high-density heat exchangers equipped with air-ducted shrouds and fans. Products in this series include DAC-035-12-02-00-00 and DAC-060-24-02-00-00.

    "Current TEA product offerings are designed with single-stage TEMs. The cooling capacity of these devices can drop to less than 30% of maximum cooling power at temperature differentials greater than 30˚C from ambient," said Andrew Dereka, Laird Technologies Thermoelectrics Product Manager. "However, at the same temperature differential, the cooling capacity of similar form factor Cascade TEAs is almost 60% of maximum cooling power. This opens up a new cooling spectrum that is currently served by conventional compressor-based systems."

    The Cascade Series TEAs are ideal for use in analytical instruments requiring cooling to well below zero Celsius. They are also applied in medical applications so the temperature of samples placed in storage compartments or centrifuges can be tightly controlled. Imaging applications utilize the TEAs to cool sensitive devices to below freezing in order to maximize the bandwidth of the light spectrum captured by the Charge-Coupled Device (CCD). The Cascade Series TEAs adhere to tight geometric space constraints by offering greater performance, higher reliability, and low cost of ownership. Their advanced capabilities are aided by new material technologies, thinner profiles, and automated assembly.
