Embodiment 1

[0040] This embodiment provides an insulating and heat-conducting potting electrical component, such as figure 1As shown, the insulating and heat-conducting potting electrical component is a radial motor, the part to be potted is the stator winding disc 4, and the cavity to be potted is the casing 1 and the stator winding disc 4 of the radial motor. In the formed cavity, the casing 1 is provided with an installation cavity, and the stator winding disk 4 and the rotor 5 rotating on the casing 1 are installed in the installation cavity. The stator winding disk 4 can have an iron core structure or a coil structure without an iron core. , The gap between the stator winding disk 4 and the housing 1 is filled with large-diameter solid particles 2 with an outer diameter of 2mm. The spherical particles are convenient to fill and flow in the gap, and the filling density is uniform. If the stator winding disc 4 is a coil structure, because the large-diameter solid particles 2 have a par...

Embodiment 2

[0042] This embodiment provides an insulating and heat-conducting potting electrical component, such as figure 2 As shown, the insulating and heat-conducting potting electrical component is a capacitor, the part to be potted is the capacitor core 6, and the cavity to be potted is the cavity formed between the shell 1 of the capacitor and the capacitor core 6, The housing 1 is provided with an installation cavity, and the capacitor core 6 is installed in the installation cavity. The gap between the capacitor core 6 and the housing 1 is filled with large-diameter solid particles 2, and the outer diameter of the particles is 2 mm.

Abstract

The invention relates to an insulating heat-conducting potting electrical element, and belongs to the technical field of electrical manufacturing. The problems that in the prior art, the glue pouring amount of electrical elements is large, and the cost is high are solved. The insulating heat-conducting potting electrical element comprises a shell, a to-be-potting part is arranged in the shell, a gap is formed between the to-be-potting part and the shell, the gap is filled with heat-conducting insulating colloid, and large-particle-size solid particles are arranged in the heat-conducting insulating colloid. The large-particle-size solid particles are arranged in the colloid, so that the use amount of the colloid can be reduced, the large-particle-size solid particles are lower in cost than the colloid and higher in heat-conducting property than the colloid, and the addition of the large-particle-size solid particles can improve the toughness of the colloid, so that the cost is reduced, the toughness of the colloid is improved, and the heat conduction effect is improved.

Description

technical field [0001] The invention belongs to the field of electrical manufacturing, and relates to a potting electrical component, in particular to an insulating and heat-conducting potting electrical component and a potting method thereof. Background technique [0002] As the market demands more and more precision and lightweight electrical components, electrical components are often accompanied by a lot of heat during operation, and there are requirements for insulation of electrical components, and the most commonly used thermal insulation in the prior art The method is to conduct the heat-generating part of the electrical component to the outside of the electrical component through the heat-conducting insulating glue through colloid potting to dissipate heat. [0003] The so-called colloid potting refers to the use of special potting glue to fill the cavity of electrical components and cure. Improving the colloidal potting can strengthen the overall strength of elect...
