AI Technical Summary
Technical Problem
As inverter power increases, fan speed increases, leading to increased noise. Existing noise reduction heatsinks cannot effectively solve the noise problem.
Method used
The noise reduction component, which combines a microphone and a speaker, generates an anti-phase sound wave with the same amplitude but opposite phase as the fan noise through an audio processing module. This creates destructive interference in the noise propagation path, thus achieving active noise reduction.
Benefits of technology
It effectively reduces the noise of the noise-reducing heat sink, maintains the efficient heat dissipation performance of the fan assembly, and avoids direct coupling interference of anti-phase sound waves, ensuring the accuracy and reliability of noise reduction.

Abstract
This application discloses a noise-reducing heat dissipation box and inverter, relating to the field of inverter technology, to solve the problem of high noise caused by increased fan speed in existing noise-reducing heat dissipation boxes. The noise-reducing heat dissipation box provided in this application includes a box body with an air inlet and an air outlet. A fan assembly is mounted on the box body, positioned close to the air inlet, to drive external air into the box through the air inlet and out through the air outlet. The noise reduction assembly includes a first microphone, a speaker, and an audio processing module mounted on the box body. The first microphone and speaker are both electrically connected to the audio processing module. The first microphone is positioned between the fan assembly and the speaker to collect noise audio from the fan assembly, and the distance between the first microphone and the fan assembly is smaller than the distance between the first microphone and the speaker. This application reduces the noise of the noise-reducing heat dissipation box by incorporating the noise reduction assembly.
