Embodiment Construction

[0007] Below in conjunction with embodiment the present invention is further described. The difference between the manufacturing method of the coil disk of an electromagnetic oven provided by the present invention and the existing coil disk manufacturing method is that the copper-clad aluminum core wire is used to make the coil. Including the following steps: (1) Winding multi-strand wires; since the induction cooker coil is a high-frequency coil, high-frequency current is generated after being energized, and the high-frequency current has a skin effect, and the outer layer of the copper-clad aluminum core is copper, and the inner layer is Aluminum, so it not only has the superior conductivity of copper, but also takes advantage of the skin effect of high-frequency current, and also combines the advantages of light weight and good plasticity of aluminum. At the same weight, the copper-clad aluminum core wire is better than the enamelled The copper core wire is 1.5 to 1.7 times...

Abstract

This invention relate to a method for manufacturing the coil disk of the induction cooker. Its feature is that: the coil disk is made of copper cladding aluminum wires. The invention of the beneficial effects : (1) it saves copper and greatly reduce production cost, (2) the plasticity of the aluminum wires is better than ones of copper wire, easy molding, (3) the Insulation Resistance and heat tolerance of the coating layer of the aluminum is better, thereby it prolongs its using-life.

Description

Technical field [0001] The invention relates to an electromagnetic cooker accessory, in particular to a manufacturing method of an electromagnetic cooker coil disk. Background technique [0002] At present, the induction cooker is widely used, and its coil disk has long been wound with traditional enamelled copper core wires. Due to the lack of copper resources in my country and the high price, the manufacturing cost of coil discs remains high. In addition, the density of copper is relatively high, and the weight of the coil disk is relatively heavy, resulting in high transportation costs. Contents of the invention [0003] In order to overcome the shortcomings of the existing enamelled copper core coil disk, the invention provides a manufacturing method for the coil disk of an induction cooker. The coil disk adopts a copper-clad aluminum core, so it is light in weight and low in cost. [0004] The technical solution adopted by the present invention to solve its technica...
