The invention relates to a wire coil, and particularly to a highly energy-gathered uniform heating wire coil. The highly energy-gathered uniform heating wire coil comprises a winding bracket, an enameled wire and a magnetic tape, wherein the enameled wire is wound on the front side of the winding bracket; the magnetic tape is clamped on the backside of the winding bracket; the highly energy-gathered uniform heating wire coil is characterized in that one end of a horizontal part of the magnetic tape is set as a recess structure or the two ends thereof are set as recess structures, and the structure of the winding bracket matches with the structure of the magnetic tape. As the existing magnetic tape structure is subjected to such the adjustment that one end of the horizontal part of the magnetic tape is set as the recess structure or two ends thereof are set as the recess structures, the recess structure needs to be formed at the front side of the winding bracket. Therefore, the number of layers of the enameled wire wound in the recess structure of the front side of the winding bracket is increased when the enameled wire is wound, magnetic sensing wires distributed in a relatively wide range of the middle part of the wire coil are enabled to be relatively dense, and the achieved heat efficiency of the wire coil at the presence of completely same other conditions such as the same electric energy and the same area is greatly higher than that of an existing product.
