Dive Summary:
- Researchers at the Public University of Navarre in Spain say they have invented an energy-free system that uses a given device's own heat to cool it down.
- The system uses thermoelectric generation to convert residual heat flow from a power convertor or transformer into energy, which the system then uses to cool the convertor or transformer.
From the article:
"... David Astrain-Ulibarrena, of the UPNA/NUP's Department of Engineering, Mechanics, Energy and Materials and head researcher in the project, explains what the system consists of: 'When these devices are functioning, they heat up and need to be cooled down.In many cases, heat exchangers with fans are used which naturally need to be powered externally and consume a certain amount of electrical power. What we do is take advantage of the heat flow emitted by the power converter and transformer to produce the electrical power needed to make the fans work. That way we achieve the cooling of the device and control its temperature, but without any energy cost.' ..."
