Dustproof plug-in box with high heat dissipation performance

Abstract

The invention discloses a dustproof plug-in box with a high heat dissipation performance, and belongs to the technical field of electricity. The dustproof plug-in box comprises an air duct component,wherein a heat dissipation module is plugged into the air duct component to form an independent air duct structure after matching; the air duct component is arranged in the dustproof plug-in box, andthe dustproof plug-in box comprises a box upper cover plate and a box lower cover plate which are connected through two oppositely arranged box side plates. According to the invention, the internal structure of the standard plug-in box is redesigned, and the air duct component and the heat dissipation module matched with the standard plug-in box are designed, so that the heat of the heat source chip is transferred to the heat dissipation module and dissipated outside the plug-in box through the air duct component, the invasion of dust and foreign matters caused by opening air holes is avoided,and the heat dissipation performance and the environmental adaptability of the plug-in box are enhanced; the number and the installation positions of the air duct components can be flexibly configured, the reasonable layout of the plug-in units is facilitated, the anti-interference capability of the circuit is improved, and the internal wiring of the device is optimized.

Description

technical field [0001] The invention belongs to the field of electrical technology, and in particular relates to a dust-proof plug-in box with high-efficiency heat dissipation performance. Background technique [0002] With the development and upgrading of smart substations and on-site devices, there have been requirements for the installation of plug-in boxes in outdoor cabinets and on-site installations, which put forward higher requirements for the IP protection level and heat dissipation performance of the devices. [0003] The existing heat dissipation method of ordinary subracks is likely to cause various problems such as lowering the protection level of the subrack, dust intrusion into the chassis, and failure of electronic components. Elevated installation requirements. [0004] When the existing 19-inch standard subracks are configured with high-power plug-ins, the upper and lower cover plates are usually opened to speed up the airflow exchange inside and outside t...
