Charging pile noise reduction device

Abstract

The invention relates to a charging pile noise reduction device. The device is characterized in that a vibration filtering box (3) is connected to the outer side of a cooling fan (2), a fan shell (4) and a noise reduction body (5) are arranged in the vibration filtering box (3), a cone noise reduction device (51), a cone fixing block (52) and a noise reduction hole area (53) are arranged in the noise reduction body (5), and each surface of the cone noise reduction device (51) is provided with a noise reflection piece (511) and a noise reduction hole (512); and the end surface of the noise reduction body (5) is connected with a dustproof device (6), and the dustproof device (6) comprises an electrostatic dustproof net (61), an anode device (63) and a cathode device (64). The device has the advantages that an aerodynamic noise transmitted out of the pile body is greatly reduced, meanwhile, the combination of noise reduction and heat dissipation functions in the pile body is considered, external dust is effectively filtered, and a mechanical noise generated by vibration during working of the heat dissipation fan is effectively buffered.

Description

Technical field [0001] The present invention relates to the technical field of new energy automotive charging equipment, in particular a charging pile noise reduction device. Background technique [0002] With the rapid development of new energy automotive technology, new energy vehicles gradually enter thousands of households. At the same time, the demand for new energy electric vehicles charging piles is getting bigger and bigger. When the charging pile is working, a large amount of heat is generated in the power module area, and the heat collector will impair the electronic components inside the pile. Currently, the pile is mainly dissipated by air cooling. However, with factors affecting the aging of fan aging and external dust into the wind turbine, there will be a large noise during operation, which seriously affects customer usage satisfaction and the lives of surrounding residents. Therefore, it is necessary to reduce the noise of the charging pile and significant. [000...
