Description

technical field [0001] The present invention relates to the technical field of servo drives, in particular, to a heat dissipation structure of a servo drive. Background technique [0002] The servo drive is a controller used to control the servo motor, mainly used in high-precision positioning systems. [0003] During the working process of the servo driver, a large number of digital signals need to be calculated, resulting in a large amount of heat generated by the servo driver. It is necessary to dissipate the heat of the servo driver in time to ensure the stable operation of the servo driver. [0004] The existing heat dissipation methods include air-cooled heat dissipation and water-cooled heat dissipation. Water-cooled heat dissipation: the equipment is compactly installed, the cost of use is high, and the heat dissipation effect is better. The air-cooled radiator runs through the fan to drive the flow of air and blow it to the servo driver to realize the heat dissipat...

AI Technical Summary

Problems solved by technology

Due to the dust in the air, the dust will adhere to the surface of the driver during the air flow process, which will easily cause a short circuit of the servo driver and affect the heat dissipation of the servo driver.

When the existing servo driver dissipates heat, the driver is installed on the heat sink, and the heat is transferred to the heat sink by means of heat conduction, increasing the heat dissipation area for passive heat dissipation, and the heat dissipation efficiency is low. Dust adheres, which affects the heat dissipation effect of the equipment. It is necessary to disassemble the heat sink and clean the dust. The operation method is complicated. Therefore, how to design a heat dissipation structure that improves the air-cooled heat dissipation efficiency and reduces the complexity of dust cleaning has become a technology in the art.
