Nano particle generator

A nano particle generator, comprising:

• a body;
• a heating unit to apply heat in direct contact to a solid-phase material received in the body such that the material is evaporated to generate evaporated material;
• and
• a channel extending through the body such that the fluid to condense the evaporated material flows along the channel to generate nano particles having sizes in a range of 1 to 100 nm,
• wherein the heating unit includes
• a heating body;
• one heating wire buried in the heating body;
• and
• at least one locating part formed in the heating body such that the material is located in the locating part,
• wherein the heating wire is mounted so that the heating wire is concentrated at one end of the heating unit, and the locating part is formed at a region where the heating wire is concentrated,
• the heating unit directly heats the material located in the locating part,
• wherein the channel is partitioned into two channels by the heating unit, and partition plates are disposed between the respective channels and the heating unit, by which fluid flowing along the channels does not directly contact the heating unit.
