Jeff Hershberger, Robert Smythe, Xiaoyi Gu and Richard F. Hill Laird Technologies, Inc. INTRODUCTION Thermoelectric cooling is an active thermal management technique. A thermoelectric cooler (TEC) has two circuit boards which are typically Al2O3 plates with copper circuit traces attached to them and semiconductor elements soldered between them. TECs are now available … [Read more...]
New Thermoelectric Material May Boost Development of Green Technologies
New material properties discovered by researchers at the University of Miami may impact ongoing research into thermoelectric materials, which are useful in power generation, energy detection and refrigeration and cooling. Lead author Joshua Cohn, professor and chairman of the UM Department of Physics, and his colleagues report new properties of a metal known as lithium … [Read more...]
High-Performing Thermoelectric Material May Improve Clean Energy Research
Researchers at the University of Houston have discovered a new thermoelectric material capable of high performance at temperatures ranging from room temperature to 300 degrees Celsius (573 degrees Fahrenheit) and possibly higher. The material is reportedly the first new high-efficiency thermoelectric material in 60 years, and could be important for both clean energy research … [Read more...]
High Power Thermoelectric Cold Plate for 19-Inch Racks
Elite Thermal Engineering, a developer of high power, high performance thermoelectric cooling devices, has released a 19-inch version of its thermoelectric cooling plate OCP-300 and high power heat sink HS-004 created for use with 19-inch rack systems in both OEM and laboratory applications.

Solving the Thermoelectric Mystery
Thermoelectric materials—substances that exhibit the so-called thermoelectric effect, in which a temperature difference creates an electric potential or vice versa—have been known for decades and employed in applications including power generation and refrigeration. Despite their commercial use, however, scientists have remained somewhat baffled as to why some of these … [Read more...]
