Problems solved by technology
[0002] A coil usually refers to a ring-shaped wire winding; some problems are still exposed during the use of the current coil. The heat generated during the use of the coil is large, resulting in excessive resistance, and the heat dissipation efficiency of the coil is not ideal. Exposed problems, it is necessary to improve and optimize the structure of the coil and its manufacturing method

The invention belongs to the technical field of coils, in particular to a spiral hollow coil, which includes a conductor, the side surface of the conductor is uniformly provided with a concave groove, and the side surface of the conductor is bonded with a connecting piece by glue. The outer surface of the sheet is provided with an extension sheet by injection molding, and the end of the extension sheet different from the connecting sheet is integrally formed with a fitting sheet, and the surface of the conductor on the side different from the connecting sheet is bonded with a connecting strip through glue, and the There is a fitting groove on the side surface of the connecting strip different from the conductor; the concave groove is evenly arranged on the side surface of the conductor, which can effectively increase the surface area of the conductor and facilitate the heat exchange between the conductor and the outside world. The conductor passes through the connecting strip during the self-winding process. Cooperating with the embedded block keeps a certain distance between the coils of conductors, increases the surface area of the conductors exposed to the external environment, and facilitates the heat dissipation of the coil.
Description
technical field [0001] The invention belongs to the technical field of coils, and in particular relates to a spiral hollow coil and a manufacturing method thereof. Background technique [0002] A coil usually refers to a ring-shaped wire winding; some problems are still exposed during the use of the current coil. The heat generated during the use of the coil is large, resulting in excessive resistance, and the heat dissipation efficiency of the coil is not ideal. To solve the exposed problems, it is necessary to improve and optimize the structure of the coil and its manufacturing method. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the present invention provides a helical hollow coil and a manufacturing method thereof, which have the characteristics of improving the heat dissipation rate of the coil and being convenient for processing and manufacturing. [0004] In order to achieve the above object, the present invent...
