Thermoelectric Assemblies About Laird Introduction Laird designs and manufactures customized, performance-critical products Thermoelectric Assemblies (TEAs) are compact units that control the temperature of for wireless and other advanced electronics applications. a wide variety of applications, such as laser diode packages in active optics, lasers in medical and industrial instrumentation, electronic enclosures, sample storage chambers Laird is a global technology company focused on providing components in medical diagnostics and analytical instruments and batteries in various automotive and solutions that protect electronic devices from electromagnetic interference and telecom applications. TEAs serve a cooling capacity spectrum from approximately and heat, and that enable connectivity through wireless applications and 10 to 400 Watts, and can cool by removing heat from control sources through antenna systems. convection, conduction, or liquid means. Custom products are supplied to all sectors of the electronics industry including the handset, telecommunications, data transfer and information technology, Advantages automotive, aerospace, defense, consumer, medical, mining, railroad and TEAs offer several advantages over other cooling technologies. For example, industrial markets. 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 As an industry leader in high-performance and cost-effective Thermal protect electronics inside enclosures from outside contaminants , and also limit moisture Management Solutions, Laird provides the knowledge, innovation, exposure from the outside environment. TEAs also offer precise temperature control and resources to ensure exceptional thermal performance and customer and accuracies to within 0.01C are achievable under steady-state conditions. satisfaction for applications in many industries including: Analytical Instrumentation TEAs have several advantages over conventional compressor-based systems: Clinical Diagnostics Semiconductor Fabrication Medical Imaging Compact size and lower weight than conventional compressor-based systems Electronic Enclosure Cooling Aerospace Defense Mountable in any orientation and have lower noise and vibration Food & Beverage Photonics Laser Systems Automotive Environmentally friendly, as TEAs do not use CFCs and are RoHS compliant Telecommunications 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.
