Abstract：Passiveradiative cooling has garnered significantatentiondue to itspotential in energy conservation andenvironmental regulation.However，thecooling powerof passiveradiativecoolingisinherentlylimited by Planck'slaw.Recent research found that positive photon chemical potential has the potential to enhance radiation power，albeit it necesitates anactive energy input.This study proposes atheoretical model integratingaheat engine andathermalradiationdiode（TRD）thatcanpasivelyachieve positivephotonchemical potential，thereby enhancingradiative coling power.Theresults demonstrate thatthe integrated system ofTRDand thermoelectric generator （TEG）can efectively improve cooling power.Theoretical results indicate that the TRD-Carnot engine coupled systemhasthe potential toachieveapeak radiation powerdensityof 606.3 W/m2when the Carnot engine operates at 300 K（hotreservoir）and 28O K（cold reservoir）．The peak radiation power density has the potential to exceed the ideal blackbody radiation density at 300K ，which is 459W/m2 .This study theoretically confirms that the synergistic effect between TRD and heat engine provides a novel approach for enhancing radiative cooling performance.
