II-VI Marlows’ ability to provide both low-cost standard products and cost-efficient, customized products remains our industry advantage. As the leading supplier of custom thermoelectric coolers (TECs), Marlow has a concept-to-completion approach to design. This approach enables II-VI Marlow to span a variety of markets and applications, offering world-class support to the customer and capturing the optimum design to match their requirements.
Why is a custom, optimized design important?
According to basic theory, TEC coefficient of performance (COP) is a strong function of ∆T across the elements. In a real-world situation, with thermal resistances due to interfaces and heat exchangers, ∆T across the elements is a function of COP. Therefore, there is a compounding effect and a severe penalty for failure to optimize at the system level. II-VI Marlow's optimization process specifically addresses minimizing TEC power consumption by system-level analysis.
Similar to Christopher Columbus navigating the vast waters of the Atlantic, Thomas Seebeck helped to plot the way for the field of thermoelectrics. Seebeck’s discoveries in the 19th century have stood the test of time and continue to be used to this day.
Along with fellow physicists Jean Peltier of the Peltier effect and Lord Kelvin of the Thomson effect, Seebeck created the foundation for the field of thermoelectrics as we know it today.Continue reading →
NASCAR has Dale Earnhardt, cooking shows have Julia Child, and thermoelectrics has Jean Peltier. While his might not be a household name, chances are his discoveries and lasting legacy has reached you in some way. Peltier, a French physicist, is responsible for discovering what are now called thermoelectric coolers and heaters.Continue reading →
