Researchers at UCLA have created a new cooling technology that utilizes the electrocaloric effect to continuously lower temperatures. The innovative design employs layers of flexing thin films that pump away heat when subjected to an electric field. In lab experiments, the prototype successfully reduced ambient temperatures by 16 degrees Fahrenheit continuously and up to 25 degrees at the heat source within 30 seconds.
A new cooling innovation developed by scientists pumps away heat continuously using layers of flexing thin films . The design is based on the electrocaloric effect , in which an electric field causes a temporary change in a material’s temperature, according to researchers.
When the electricity switches off, the stacked pairs come apart to then press against the other neighboring layers. As this alternating process repeats itself, the self-regenerative, accordion-like cascading action continually pumps heat away, layer by layer, according to a press release.
