A design engineer should consider TEMs when the system electromagnetic interference and heat, and that enable connectivity design criteria includes such factors as precise temperature control, in mission-critical wireless applications and antenna systems. high reliability, compact geometry constraints, low weight and We are a global leader in the field of radio frequency (RF) engineering environmental friendly requirements. and in the design, development and supply of innovative technology that allows people, organisations and applications to connect efficiently. Benefits of Using Our aim is to be a trusted partner to our customers by delivering problem-solving solutions through Innovation, Reliable Fulfilment, Thermoelectrics and Speed. TEMs have several advantages over alternate cooling technologies: Laird partners with its customers to design custom thermal solutions for applications in many industries including: They have no moving parts, so the solid state construction results in high reliability and units can be mounted in any orientation. Medical Diagnostics TEMs can cool devices down to well below ambient. Colder Medical Imaging temperatures can be achieved, down to minus 100C, by using Baertt y Cooling a multistage thermoelectric module in a vacuum environment. Industrial Laser Systems Thermoelectrics are able to heat and cool by simply reversing the polarity, which changes the direction of heat transfer. This allows Optoelectronics temperature control to be very precise, where up to 0.01C can Analytical Instrumentation be maintained under steady-state conditions. Semiconductor Fabrication In heating mode, TEMs are much more efficient than Aerospace Defense conventional resistant heaters because they generate heat from input power supplied plus additional heat generated by Food & Beverage the heat pumping action. Automotive Devices are environmentally friendly because they use no CFCs As an industry leader in high-performance Engineered Thermal and electrical noise is minimal. Systems that demand high system uptime, Laird provides the TEMs can be used as energy harvesters, turning waste heat into knowledge, innovation, and resources to ensure exceptional usable output DC power. thermal performance and customer satisfaction for applications in the medical, analytical, telecom, industrial, and consumer markets. A Brief Introduction to Thermoelectrics Solid state heat pumps have been in existence since the discovery of the Peltier effect in 1834. The devices became commercially available several decades ago with the development of advanced semiconductor thermocouple materials in combination with ceramics substrates. Thermoelectric modules (TEMs) are solid-state heat pumps that require a heat exchanger to dissipate heat utilizing the Peltier Effect. During operation, DC current flows through the TEM to create heat transfer and a temperature differential across the ceramic substrates, causing one side of the TEM to be cold, while the other side is hot. A standard single-stage TEM can achieve temperature differentials of up to 70C. A typical TEMs geometric footprint can vary from 2 x 2 mms to 62 x 62 mms and are light in weight. This makes thermoelectrics ideal for applications with tight geometric space constraints and low weight requirements when compared too much larger cooling technologies, such as conventional compressor-based systems. TEMs can also be used as a power generator to convert waste heat into usable output DC power.
