Patent ID: 7935169

Claim:
An apparatus for manufacturing metal nanoparticles, comprising: a precursor supplying part which supplies a precursor solution of metal nanoparticles; a first heating part which is connected with the precursor supplying part, includes a reactor channel having a diameter of 1 to 50 mm, and is heated to the temperature range where any particle is not produced; a second heating part which is connected with the first heating part, includes a reactor channel having a diameter of 1 to 50 mm, and is heated to the temperature range where particles are produced; and a cooler which is connected with the second heating part and collects and cools metal nanoparticles produced at the second heating part, wherein at least one of the first heating part and the second heating part has a reactor channel which is a spiral-shaped condenser type and of which around oil fluid circulates.
