AI Technical Summary
Technical Problem
The fans in ventilation therapy equipment are quite noisy and require effective noise reduction measures.
Method used
Design a flow guide structure for a noise reduction device, in which the fluid flows out after undergoing at least one angular turn in the fluid chamber, and consumes sound wave energy through reflection and refraction. This includes the design of the included angle between the fluid inlet and the fluid outlet, as well as the material and position setting of the closed end.
Benefits of technology
It effectively reduces the noise level of ventilation therapy equipment by consuming sound wave energy through changes in fluid direction, thereby achieving the purpose of noise reduction.
