Thermoelectric Elements Miniaturization

In electronics, everyone has seen the beneficial impact of miniaturization. Exponential increases in computing power and ever-decreasing package sizes are evident in the evolution of cell phones, MP3 players, laptops and a whole host of other electronic devices. Historical trends have followed Moore's Law, which predicts that the number of transistors on integrated circuits doubles every 18 months. Feature sizes on current computer chips are now measured on the nanometer scale. Can thermoelectrics benefit from this type of scaling? “Smaller” and “more powerful” are generally positive attributes, but what are the implications unique to thermoelectrics when it comes to miniaturization and scaling?

Thermoelectric Power Generation

The vast majority of government-sponsored research in the field of thermoelectrics over the past 10-15 years has been in the area of thermoelectric power generation. The driving force behind most of this research seeks ways to improve our utilization of energy. Consider that less than a fourth of the energy content in the gasoline in your car actually goes into useful work to move the vehicle. The majority of the energy escapes as heat loss to the ambient primarily through the vehicle exhaust and radiator. Likewise, the U.S. manufacturing industry discharges roughly one-third of the energy consumed as thermal losses to the atmosphere or to cooling systems. This heat loss is measured in Quads (1015 BTU) and represents a huge opportunity for thermoelectrics to someday impact national energy consumption and our dependence on foreign fuel.

Optimum Thermoelectric Design: Concept to Completion

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.
