Problems solved by technology

[0002] Existing servo drive manufacturers use the internal fan of the drive to provide the air source for heat dissipation, combined with the openings at both ends of the drive shell, the internal air duct, and the air guide column to discharge the heat from the radiator to achieve the purpose of cooling the servo drive. The cooling capacity of the heat dissipation method is limited, and the heat dissipation effect of the over-high-power components is average, and the low-power model has a compact structure and cannot be equipped with a fan. not functioning properly

Abstract

The invention relates to a heat dissipation structure of a servo drive and a control cabinet including the same. A heat dissipation air duct and a heat pipe are arranged in the cabinet of the servo drive. The evaporation section of the heat pipe contacts each heating component of the servo drive. There is a working medium inside the heat pipe, and the working medium can absorb the heat transmitted to the evaporation section and undergo a liquid-gas phase change, then flow to the condensation section and undergo a gas-liquid phase change in the condensation section, and cooperate with the air duct to discharge the heat, The setting of the heat pipe and its internal working medium can quickly take away the heat of the servo drive, and solve the heat accumulation problem of the traditional servo drive heat dissipation structure. In this way, there is no need to set fans and cooling holes inside the servo drive, which greatly reduces the size, volume and weight are effectively reduced, and is suitable for control cabinets of various power types.

Description

technical field [0001] The invention relates to the technical field of heat dissipation, in particular to a heat dissipation structure of a servo driver and a control cabinet including the same. Background technique [0002] Existing servo driver manufacturers use the internal fan of the driver to provide the air source for heat dissipation, combined with the openings at both ends of the driver's shell, the internal air duct, and the air guide column to discharge the heat from the radiator to achieve the purpose of cooling the servo driver. This air-cooled The cooling capacity of the heat dissipation method is limited, and the heat dissipation effect of the over-high-power components is average, and the low-power model has a compact structure and cannot be equipped with a fan. not functioning properly. Contents of the invention [0003] Aiming at the problems existing in the above-mentioned prior art, the present invention provides a servo drive heat dissipation structure...
