摘要： A noise reduction assembly includes an outer frame and a partition plate. An accommodating cavity is arranged in the outer frame; the partition plate is arranged in the accommodating cavity, and the partition plate and the outer frame form a noise reduction channel, the noise reduction channel includes a first noise reduction section, a second noise reduction section and a third noise reduction section that are communicated in sequence, and the channel cross-sectional areas of the first noise reduction section and the third noise reduction section are both smaller than the channel cross-sectional area of the second noise reduction section. The technical solution of the present application may reduce the noise of a new energy equipment having the noise reduction assembly during operation.

摘要： The present application relates to the technical filed of heat dissipation for inverters, and in particular to a fan assembly and an inverter. The fan assembly includes a fan guard, a fan body and a noise reduction mounting member. The fan body directly faces an air inlet, the air inlet is covered by a fan guard, and the noise reduction mounting member is arranged on the fan body, to provide a preset distance between the fan body and the fan guard, and the noise reduction mounting member is configured to mount the fan body on a to-be-mounted component in a buffered manner. The distance between the fan body and the fan guard can reach the preset distance due to the noise reduction mounting member, so as to avoid the formation of high-order vortex when the air flows through the fan guard, which reduces the aerodynamic noise. In addition, the noise reduction mounting member plays a vibration isolation function between the fan body and the to-be-mounted component, which improves the sound quality. With the fan assembly, the inverter according to the present application can avoid resonance between the fan body and the to-be-mounted component, which reduces the aerodynamic noise and improves the sound quality.
