摘要： PROBLEM TO BE SOLVED: To improve heat radiation characteristic of a bobbin winding coil, and to provide a coil winding method for manufacturing such bobbin winding coil.SOLUTION: A bobbin winding coil of the present invention includes a bobbin 2 containing a plurality of winding space regions S1-S3 mutually partitioned with a wall 2d in axial direction of a core body 2c, and a coil 3 which is wound on the core body 2c in each of the winding space regions S1-S3 so as to form a coil layer from the inside to the outside, and between two winding space regions, a winding end of an outermost coil layer in one region connects to a winding end of an innermost coil layer in the other region, such that the coil is wound around the bobbin by a predetermined number of turns as a whole. Since, in such bobbin winding coil, the winding end of an outermost coil layer in one region connects to the winding end of an innermost coil layer in the other region, the heat in the innermost coil layer is propagated to the outermost coil layer, for promoting heat radiation. Thus, a temperature of the innermost coil layer which is continued from the outermost coil layer in the other region is dropped.
摘要翻译：要解决的问题：为了提高筒管绕线圈的散热特性，并提供一种用于制造这种线圈绕组线圈的线圈绕制方法。解决方案：本发明的绕线线圈包括：线轴2，其包含与芯体2c的轴向方向上的壁2d相互隔开的多个绕组空间区域S1-S3，以及缠绕在线圈3上的线圈3 在每个绕组空间区域S1-S3中的芯体2c形成从内向外的线圈层，并且在两个绕组间隔区域之间，一个区域中的最外侧线圈层的绕组端连接到绕组在另一区域中的最内侧线圈层的端部，使得线圈整体围绕线轴缠绕预定匝数。由于在这样的绕线线圈中，一个区域中最外侧的线圈层的绕组端部与另一区域的最内侧的线圈层的绕组端部连接，所以最内侧的线圈层的热量传播到最外侧的线圈层，促进热辐射。因此，从其他区域中的最外侧线圈层继续的最内侧线圈层的温度下降。版权所有（C）2013，JPO＆INPIT
