Here, we demonstrate an interpenetrating architecture of electrocaloric polymer with highly thermally conductive pathways that achieves a 240% increase in the electrocaloric performance and a 300% enhancement in the thermal conductivity of the polymer. A scaled-up version of the device prototype for a single heat spot cooling of 5 G chip is fabricated utilizing this electrocaloric composite and electromagnetic actuation. The continuous three-dimensional (3-D) thermal conductive network embedded in the polymer acts as nucleation sites of the ordered dipoles under applied electric field, efficiently collects theNature communicationshttps://www.ebi.ac.uk/biostudies/studies/S-EPMC9532434biostudies-literatureThermal management of chips by a device prototype using synergistic effects of 3-D heat-conductive network and electrocaloric refrigerationPMC9532434Li JShen QGan JWang FChen XWang XShen XLi MfalseThermal management of chips by a device prototype using synergistic effects of 3-D heat-conductive network and electrocaloric refrigerationWith speeding up development of 5 G chips, high-efficient thermal structure and precise management of tremendous heat becomes a substantial challenge to the power-hungry electronics.
