Method for producing line output transformer shell with high thermal diffusivity

Abstract

The invention discloses a method for producing a line output transformer shell with a high thermal diffusivity. The method comprises the following steps: melting ABS resin and polypropylene to obtaina mixture a; mixing and grinding negative ion powder, tourmaline, ferric acetylacetonate, talcum powder, sodium gluconate and carboxymethylcellulose sodium to obtain a mixture b; mixing the mixture awith the mixture b, and uniformly stirring the mixture a and the mixture b in order to obtain a mixture c; melting, molding and cooling the mixture c to obtain a green body d; homogenizing the green body, and cooling the homogenized green body with water to obtain a line output transformer shell matrix; and smearing a thermal diffusion material on the surface of the line output transformer shell matrix, and drying the surface to obtain the line output transformer shell, wherein the thermal diffusion material comprises modified viscose-based carbon fibers, nanometer silicon nitride, a couplingagent, naphthenic oil and ethanol. The method is simple, is friendly to the environment and is suitable for industrial production, and the produced line output transformer shell has excellent thermaldiffusivity, excellent insulating property and excellent ageing resistance.

Description

technical field [0001] The invention relates to the technical field of high-voltage packs, in particular to a method for preparing a shell of a high-voltage pack with high heat dissipation. Background technique [0002] The high-voltage pack is commonly known as the line output transformer, and the output of high-voltage direct current is the function of the high-voltage pack. This function is exactly the same as the high voltage pack in the TV. When used in a TV, it is used to accelerate the electronic screen to achieve sufficient brightness. When used in a computer LCD screen, it can supply power to the lamp to make the screen achieve sufficient brightness. [0003] When the high-voltage package is working, the internal coil will generate a lot of heat. With the continuous increase of power load, if the heat generated by the coil is not dissipated in time, it will not only damage the internal components, but also affect the normal operation of the transformer. The high-v...
