Thermoelectric Assemblies About Laird Introduction Laird is a global technology company focused on providing Thermoelectric Assemblies (TEAs) are compact units that control the systems, components and solutions that protect electronics from temperature of a wide variety of applications, such as laser diode packages electromagnetic interference and heat, and that enable connectivity in active optics, lasers in medical and industrial instrumentation, electronic in mission-critical wireless applications and antenna systems. enclosures, sample storage chambers in medical diagnostics and analytical instruments and batteries in various automotive and telecom applications. We are a global leader in the field of radio frequency (RF) engineering TEAs serve a cooling capacity spectrum from approximately 10 to 400 and in the design, development and supply of innovative technology Watts, and can cool by removing heat from control sources through that allows people, organisations and applications to connect efficiently. convection, conduction, or liquid means. Our aim is to be a trusted partner to our customers by delivering problem-solving solutions through Innovation, Reliable Fulfilment, Advantages and Speed. TEAs offer several advantages over other cooling technologies. For example, conventional fan trays do not cool to below ambient and Laird partners with its customers to design custom thermal solutions require an air exchange with the outside environment. On the other for applications in many industries including: hand, TEAs can cool to well below ambient and protect electronics inside enclosures from outside contaminants, and also limit moisture • Medical Diagnostics • Analytical Instrumentation exposure from the outside environment. TEAs also offer precise • Medical Imaging temperature control and accuracies to within 0.01˚C are achievable • Semiconductor Fabrication under steady-state conditions. • Battery Cooling • Aerospace Defense • Industrial Laser Systems • Food & Beverage • TEAs have several advantages over conventional • Optoelectronics compressor-based systems: • Automotive • Compact size and lower weight than conventional As an industry leader in high-performance Engineered Thermal compressor-based systems Systems that demand high system uptime, Laird provides the • Mountable in any orientation and have lower noise and vibration knowledge, innovation, and resources to ensure exceptional thermal performance and customer satisfaction for applications • Environmentally friendly, as TEAs do not use CFCs and are RoHS in the medical, analytical, telecom, industrial, and consumer markets. 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/ Cascade Series 35 – 60 Watts 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 PowerCool Series 19 – 195 Watts operating voltages are 12 and 24 VDC, and on some models 48 VDC. The standard product offering includes heat transfer mechanisms Tunnel Series Outdoor Cooler Series 11 – 39 W 102 – 480 Watts designed to absorb and dissipate heat by convection, conduction, or MRC Chiller Series through liquid heat exchangers. All products are manufactured in an ISO 150, 300 Watts 9001:2008 certified facility and are designed to meet the cooling needs of many thermal management applications in the medical, analytical, 0 Cooling Capacity (W) 480 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.
