Solid-state heatpumps, thermocoolers, thermoelectric coolers, Peltier or simply TECs - all these names refer to a device based on the Peltier-effect. TEC Microsystems GmbH is in a position to offer miniature thermoelectric coolers manufactured by the company RMT Ltd, an experienced maker specialized in micro cooling solutions for Laser and Optoelectronics Applications. There are more than 1000 standard types of thermoelectric coolers available. Cold sides range from 1 x 2 mm² to 18 x 18 mm², maximum current ranges from 0.3 to 10 Amp, dTmax - from 70°C in single stage up to 150°C in multi-stage configurations (specified at 27°C, vacuum).
Depending on size and performance all TE coolers are divided into several Series. We recommend the software TECCad for optimal thermoelectric cooler selecting and analysis at different conditions, or our On-Line TEC Select Assistant for fast search and selecting of the type you need for your application. You’re also welcome to contact us – we would be glad to assist you.
MC Series of Single and Multi-Stage thermoelectric coolers
Basic large series designed for cooling and thermostabilization of microchips, IR instruments and elements of semiconductor quantum electronics. Due to the use of high quality materials, MC Series micro thermoelectric coolers provide increased dTmax and higher cooling capacity. Thermoelectric coolers are optimal for components of microelectronics by dimensions and power requirements. Many options are available: TEC shapes, terminal wires, surface finish and use of different high quality ceramics. MC Series consists of three Sub-Series by pellets cross-section, electrical parameters and performance options: MC04, MC06 and MC10.
MD Series of Single and Multi-Stage thermoelectric coolers
Feature of this new MD series of miniature thermoelectric coolers is in increased cooling capacity and very miniature dimensions possibility. Cooling power density of is up to 15 W/cm² (additionally up to 25 W/cm²). That is a result of increased density and very low profile of thermoelements - pellets.
The series consist of three Subseries: MD03, MD04 and MD06. More than 250 different thermoelectric cooler types are available, from single to four stage.
Single-stage Thermoelectric Coolers for Telecom Applications
Thermoelectric Coolers from this Series are specially optimized for cooling in DWDM applications. Typical telecom standard TECs of 17, 23, 29 and 35 couples (Bi-Te elements inside TEC) are available. Each type can be provided in different ceramics options: Alumina and Aluminum Nitride with different thicknesses.
Thermoelectric Coolers with Special Configurations
The classical connection between Bi-Te elements (pellets) inside thermoelectric coolers is serial. The typical way to change thermoelectric coolers electrical/performance parameters is in changing of pellet Bi-Te elements) height. However, there are several ways to modify the construction of TEC and obtain results, optimized for some custom applications, using combination of different pellet heights (for multi-stage TEC types), parallel connection instead of serial or a combination of both solutions.
Thermoelectric Coolers for Telecom Applications with increased Cooling Capacity
Based on High Density pellets placement technology thermoelectric coolers of 1MDL06 Series have about 40% more pellets (elements inside TEC) on the same size as standard thermoelectric cooler. Together with ultra-low profile pellets of 0.3mm height it increases cooling capacity of TEC more than twice. Check the review of 1MDL06 Series.
