High-cooling enameled copper flat wire with good flexibility

Abstract

The invention discloses a high-cooling enameled copper flat wire with good flexibility. The high-cooling enameled copper flat wire with good flexibility comprises a copper flat wire core, wherein a magnetic particle coating layer, a first aromatic polyimide paint layer, a tear-resistant layer, a second aromatic polyimide paint layer and a waterproof layer are sequentially arranged at an outer sideof the copper flat wire core, the tear-resistant layer comprises multiple Kevlar fiber bundles which are distributed at equal distance, polyamide-imide insulation paint is coated in a gap between anouter surface of the Kevlar fiber bundle and adjacent Kevlar fiber bundle, semi-cylindrical grooves are formed in an outer surface of the copper flat wire core at equal distance, an insulation film isarranged between the semi-cylindrical grooves and the magnetic particle coating layer, and the Kevlar fiber bundle is of a net-shaped structure formed by twisting seven strands of Kevlar fibers. Thehigh-cooling enameled copper flat wire has the advantages of good flexibility and good cooling performance.

Description

technical field [0001] The invention relates to an enamelled copper flat wire, in particular to an enamelled copper flat wire with good flexibility and high heat dissipation. Background technique [0002] With the rapid development of my country's electrical and mechanical industries, the concept of mechatronics has long been deeply rooted in the hearts of the people. Enameled wire, as an indispensable wire material for electrical appliances or motors, also needs continuous improvement and improvement to adapt to the new environment. Enameled copper flat wire is due to Its excellent properties such as chemical corrosion resistance, high thermal shock resistance, and thermal aging have been used in various electronic wire industries. However, the existing enamelled copper flat wires have poor flexibility and often have enameled wire tearing. Although they have good high temperature resistance performance, but it is difficult to quickly dissipate heat after high-speed movement, ...

[0002] With the rapid development of my country's electrical and mechanical industries, the concept of mechatronics has long been deeply rooted in the hearts of the people. Enameled wire, as an indispensable wire material for electrical appliances or motors, also needs continuous improvement and improvement to adapt to the new environment. Enameled copper flat wire is due to Its excellent properties such as chemical corrosion resistance, high thermal shock resistance, and thermal aging have been used in various electronic wire industries. However, the existing enamelled copper flat wires have poor flexibility and often have enameled wire tearing. Although they have good high temperature resistance performance, but it is difficult to quickly dissipate heat after high-speed movement, long-term use will cause a short circuit between turns of the coil, and it is difficult to go to international occasions

Therefore, the existing enamelled copper flat wire has the disadvantages of poor flexibility and poor heat dissipation performance.
