Thermoelectric Assemblies About Laird Laird is a global technology company focused on providing systems, components and solutions that protect electronics from electromagnetic interference and heat, and that enable connectivity in mission-critical wireless applications and antenna systems. Introduction We are a global leader in the field of radio frequency (RF) engineering and in the design, development and supply of innovative technology that allows people, organisations and applications to connect efficiently. Thermoelectric Assemblies (TEAs) are compact units that control the temperature of a wide variety of applications, such as laser diode packages in active optics, lasers in medical and industrial instrumentation, electronic enclosures, sample storage chambers in medical diagnostics and analytical instruments and batteries in various automotive and telecom applications. TEAs serve a cooling capacity spectrum from approximately 10 to 400 Watts, and can cool by removing heat from control sources through 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, and Speed. Advantages Laird partners with its customers to design custom thermal solutions for applications in many industries including: • Medical Diagnostics • Analytical Instrumentation • Medical Imaging • Semiconductor Fabrication • Battery Cooling • Aerospace Defense • Industrial Laser Systems • Food & Beverage • Optoelectronics • Automotive As an industry leader in high-performance Engineered Thermal Systems that demand high system uptime, Laird provides the knowledge, innovation, and resources to ensure exceptional thermal performance and customer satisfaction for applications in the medical, analytical, telecom, industrial, and consumer markets. TEAs offer several advantages over other cooling technologies. For example, 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 protect electronics inside enclosures from outside contaminants, and also limit moisture exposure from the outside environment. TEAs also offer precise temperature control and accuracies to within 0.01˚C are achievable under steady-state conditions. • TEAs have several advantages over conventional compressor-based systems: • Compact size and lower weight than conventional compressor-based systems • Mountable in any orientation and have lower noise and vibration • Environmentally friendly, as TEAs do not use CFCs and are RoHS 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 There are five distinct TEA product families that were designed for a specific cooling capacity range, temperature differential range or tight space constraint. The diagram to the right is a perceptual map of a cooling spectrum that can be used to guide designers to a particular product family that will have the desired attributes that the application requires. Thermoelectric Applications Cascade Series 35 – 60 Watts Temperature Differential (ΔT) Laird offers the widest selection of TEAs on the market. Products are designed and manufactured to strict process control standards and pass/ 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 operating voltages are 12 and 24 VDC, and on some models 48 VDC.
