Laird Technologies Releases the Next Generation of Tunnel Series Thermoelectric Assemblies

Compact Design Yields Higher Cooling Performance, Less Power Consumption

 

St. Louis, Missouri, USA – December 10, 2009 – Laird Technologies, Inc., a global leader in the design and manufacture of customized, performance-critical components for wireless systems and other advanced electronics applications, today announced the release of its newly modified Tunnel Series Thermoelectric Assemblies (TEAs).

The Tunnel Series TEAs are designed with a patented, high-performance cross flow technology maximizing heat transfer when pulling air through a heat exchanger. Heat is absorbed and dissipated through a high density heat sink equipped with sheet metal shrouds and fans. The number of airflow paths required is minimized when compared to traditional impingement flow TEAs. The Thermoelectric Modules (TEMs) are custom designed to achieve a high coefficient of performance (COP) to minimize power consumption with reliable solid-state operation that does not use a compressor or CFC refrigerants.

The Tunnel Series TEAs are available in two cooling configurations:

  • Air-Air (AA) – Convection cooling method where heat is absorbed and dissipated by heat exchangers equipped with fans. Products in this series include AA-027-12-22 and AA-035-24-22.
  • Direct-Air (DA) – Conduction cooling method where heat is absorbed through a cold plate, pumping the heat through the TEM and dissipating it into the air through a heat sink equipped with a fan. Products in this series include DA-033-12-02 and DA-039-12-02.
  •  

    “Conventional TEAs use impingement flow to convect heat from heat exchangers. This can pose a challenge for medical, analytical and photonics instruments with tight geometric space constraints,” stated Andrew Dereka, Laird Technologies Thermoelectrics Product Manager. “The Tunnel Series are compact TEAs that maximize cooling capacity and efficiency, while minimizing the number of air circulation paths required to operate properly.”

    The Tunnel Series TEAs are ideal for use in cooling applications with 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.
