Localized heating device and localized heating system having the same

A localized heating system, comprising:

• a plasma producing source, providing a plasma flow;
• a localized heating device, including:
• a plasma deforming portion, including:
• an inlet end, having a circular hole, connected with a plasma producing source;
• an outlet end, having an elongated hole, the elongated hole having a first length and a first width perpendicular to each other, the first length being parallel to a first direction, the first direction and an axis of the circular hole being perpendicular to each other;
• and
• a channel, connected with the circular hole and the elongated hole;
• and
• a heating portion, including two control covers, the two control covers being spaced to each other by a slot having a first distance, the slot having a second length parallel to the first direction, the slot being parallel to the axis and having a second width, the heating portion being disposed at the outlet end of the plasma deforming portion, the first length and the second length being parallel to each other, the elongated hole and the slot being oppositely disposed, a plasma flow provided by the plasma producing source being to enter the channel via the circular hole, then to flow through the elongated hole, and finally to reach the slot;
• and
• a fixture, configured for loading a workpiece, driven to displace an edge of the workpiece to enter the slot for undergoing a plasma treatment.
