Advantages of Additive Manufactured Cold-sprayed Thermoelectric Generators

 

Supersonic cold-spray technology has not been widely used for the deposition of crystalline materials, and in particular thermoelectric semiconductor materials. TTEC patented and patent pending technology enables the complete additive manufacturing of thermoelectric generator, and thermoelectric cooler systems and a wider range of energy harvesting materials and applications.

 

Why Cold-spray?

Semiconductor composition, phase and TE properties maintained

TEGs can be applied directly to 3D shaped heat sources

All metallic and semiconductor layers can be sequentially sprayed

Large area depositions possible

Thin layer semiconductor deposition for enhanced power output

Micro and nano-structured layered TE materials

Improved TEG mechanical and thermal shock resistance

Eliminates the need for output limiting solders

Unique low-temperature properties

Decreased cost per installed watt using a robotic additive manufacturing process

Applications

Complex shaped industrial process waste heat sources

Directly applied IOT power sources

Enhanced potential for IC engine applications

Thermal sensing

Small RTG's

Solar power systems enhancement

Low-grade waste heat sources
