Fundamental thermoelectric technology patent granted to DTP Thermoelectrics

20 October 2022

DTP Thermoelectrics has been awarded a patent that opens the door for solid-state deep cooling thermal management. The patent is based on theoretical and analytical models that have been validated through the fabrication and characterization of thermoelectric devices that use distributed transport properties (DTP) thermoelectric materials.

Sample tests using standard protocols demonstrate significant increases in maximum cooling temperature, efficiency (coefficient of performance) and cooling power, confirming that DTP devices can cool to lower temperatures, improving performance and functionality. Until now, these capabilities were only possible using much larger and heavier mechanical cooling systems.

"There is no better performing thermoelectric material system than what we have fabricated with our DTP technology,” said Dr. Lon E. Bell, president and CEO. “This mass-producible, proprietary technology increases cooling capacity at efficiencies greater than what is possible with other thermoelectric devices. DTP technology has the potential to improve cooling and thermal management system performance and cost effectiveness in Lidar, infrared sensors, electronics, cold chain storage, medical devices, battery thermal management and vision systems."

The patent for "Thermoelectric Systems Employing Distributed Transport Properties to Increase Cooling and Heating Performance" (number 11,421,919 by the U.S. Patent and Trademark Office) covers DTP technology and its ability to increase cooling and heating performance in solid-state heat pumps.
