A lacquer hollow copper electromagnetic wire and a manufacturing method thereof

Abstract

A lacquer hollow copper electromagnetic wire and a manufacturing method thereof, belongi to the technical field of components for electric equipment, The lacquer hollow copper electromagnetic wire comprises a capillary copper tube, a bottom coating, an intermediate coating and an outer coating are arranged from the inside to the outside of the surface of the capillary copper tube.,The bottom coating is a polyester imide insulating layer. The intermediate coating is a polyamideimide insulating layer. The outer coating is a lubricant material layer. The manufacturing method of the painted hollow copper magnet wire includes wire drawing, surface cleaning, painting, baking, cooling treatment and winding, The invention has the advantages that the manufacturing process of the painted hollow copper electromagnetic wire is simple, the primary battery reaction caused by contacting with other metals is avoided, the influence of humid environment is avoided, and the electromagnetic wire in thehigh-frequency circuit can be replaced, the heat dissipation effect is improved, the material is saved, and the application field of the hollow copper electromagnetic wire is wider.

Description

technical field [0001] The invention relates to the technical field of electrical equipment components, in particular to a painted hollow copper magnet wire and a manufacturing method thereof. Background technique [0002] In the refrigeration system of refrigerators and air conditioners, capillary copper tubes are used for throttling and current limiting. Since the throttling capillary copper tubes will contact other aluminum tubes and metal parts during operation, in humid environments, copper, aluminum or There will be a galvanic reaction between copper and other metals, which will cause corrosion on the surface of the copper tube. In severe cases, corrosion holes will appear, causing the refrigerant in the refrigeration system to leak, which will cause the refrigeration system to fail, and the refrigerator and air conditioner will not work. Moreover, this capillary copper tube is generally suitable for refrigeration systems, and its application is relatively single, but ...

Problems solved by technology

[0003] In order to solve the above technical problems, the present invention provides a paint-coated hollow copper magnet wire and its manufacturing method, which mainly solves the problem that the paint-coated hollow copper magnet wire used in the existing refrigeration system is prone to produce primary batteries with other metal parts in a humid environment. The problem of leakage of refrigerant and failure of the refrigeration system further solves the problem of single purpose of the existing painted hollow copper magnet wire. The purpose is to avoid contact with other metals by designing a painted hollow copper magnet wire Produce galvanic reaction, avoid the influence of humid environment, and this painted hollow copper magnet wire can also replace the magnet wire in the high-frequency circuit, which not only improves the heat dissipation effect, but also saves materials, making it more widely used
