Abstract

The invention provides an independent air duct structure of a servo driver. The independent air duct structure comprises a shell assembly and a forced heat dissipation assembly. A substrate of the forced heat dissipation assembly divides a cavity in the shell assembly into a first isolation cavity and a second isolation cavity which are independent of each other; a power assembly of the servo driver is arranged in the first isolation cavity, and the forced heat dissipation assembly is arranged in the second isolation cavity. The cavity in the shell assembly is divided into the first isolationcavity and the second isolation cavity which are independent by the substrate of the forced heat dissipation assembly, and the power assembly and the forced heat dissipation assembly are arranged in the first isolation cavity and the second isolation cavity respectively, so that complete isolation of the power assembly and the forced heat dissipation assembly is realized; the technical problems that the heat dissipation performance of a fan is reduced and dust is accumulated on a circuit board due to the fact that the air duct and the circuit board cannot be completely isolated are solved.

Description

technical field [0001] The present invention and the technical field of servo drives, in particular, relate to an independent air duct structure of a servo drive. Background technique [0002] In the servo system, the internal work needs to integrate a large number of electronic devices, which will generate more heat during operation. Therefore, in order to prevent the servo drive from overheating, it is usually equipped with a cooling fan to cool it down. At present, there are generally two types of servo drives for fan heat dissipation, heat dissipation without air duct and heat dissipation with air duct. Among them, the heat dissipation fan without air duct directly blows the heating components, which will lead to low working efficiency of the fan and circuit board footprint. There is an air duct for heat dissipation. Although a simple air duct is built, it cannot completely isolate the air duct from the circuit board, which will also lead to the reduction of fan cooling ...
