    • A portable induction tool is provided for soldering or brazing sections of metal pipe together. A work coil head (with induction coil) is U-shaped, allowing placement of the head around lengths of pipe, heating a susceptor (e.g., the pipe) to form a joint, and then to be withdrawn after the pipe joint is made. In one form, the tool uses heat pipes to remove thermal energy from the head, and also a heat exchanger for higher-powered units. Power capacitors are generally included with the induction (work) coil to create a tank circuit of a resonant frequency. The induction coil uses Litz wire, copper tubing, or heat pipes with a conductive outer skin to carry the high-current being delivered to the induction coil. The induction coil has a general racetrack configuration, which is typically wound in a U-shape (or as a semicircle) as a single winding, with multiple turns.
    • 提供便携式感应工具,用于将金属管的部分焊接或钎焊在一起。 工作线圈头(带有感应线圈)是U形的,允许头部围绕管的长度放置,加热基座(例如管)以形成接头,然后在制造管接头之后被抽出。 在一种形式中,该工具使用热管从头部除去热能,以及用于更高功率单元的热交换器。 感应(工作)线圈通常包括功率电容器,以产生谐振频率的电路。 感应线圈使用带有导电外皮的Litz线,铜管或热管来承载传递到感应线圈的大电流。 感应线圈具有通常的跑道结构,其通常以多匝绕作为单个绕组的U形(或半圆形)。
