The invention relates to a power resistor of a three-dimensional network structure and a processing technique of the power resistor. The power resistor comprises a resistor material layer and a three-dimensional insulating network body base material, wherein the resistor material layer is arranged on the surface of the three-dimensional insulating network body base material and jointly forms a power resistor body of the three-dimensional network structure together with the three-dimensional network structure body base material. The resistor material layer of the power resistor is attached to the surface of the three-dimensional insulating network body base material and jointly forms the three-dimensional network structure together with the three-dimensional insulating network body base material; as the three-dimensional network structure is internally overhead, the inside of the power resistor has a good permeable action, and quick cooling can be realized.
Description
technical field [0001] The invention relates to a power resistor, in particular to a three-dimensional network structure power resistor and its processing technology. Background technique [0002] The existing resistors are mainly divided into carbon film resistors, carbon resistors, metal film resistors, wire wound resistors, etc., as well as special resistors such as varistors and thermistors. [0003] Taking the metal film resistor as an example, the inside is a metal film, and the outside is wrapped with ceramic or cement materials to form a compact structure; during the working process, the heat generated by the metal film is difficult to dissipate. Especially when the power of the resistor is large, it will generate more heat when it is applied to a high-power circuit. If the harmful heat cannot be dissipated in time, the resistor will burn out. Contents of the invention [0004] The object of the present invention is to provide a three-dimensional network structure...
