Jet atomization cooling device and method

The invention provides a jet atomization cooling device and method. The device comprises a shell, an air supply mechanism, a heat exchange pipeline, a jet flow atomization mechanism and a liquid supply mechanism. The heat exchange tube bundle and the jet flow atomizing nozzle are arranged based on the air cooling channel, when a cooled working medium is fed into the heat exchange tube bundle, the air supply mechanism is used for air cooling, the jet flow atomizing nozzle is used for spraying cooling liquid, and the two modes of air cooling and spraying cooling are both considered. And jet atomization spraying is adopted, so that the size of liquid particles can be reduced and improved, and the evaporation rate of the liquid particles is improved. And the multiple sets of heat exchange tube bundles and the multiple sets of jet flow atomizing nozzles are correspondingly arranged, the problem that cooling liquid is sprayed unevenly can be effectively solved, and liquid films on the wall faces of the heat exchang
