Description

Technical Field

[0001] The present invention relates to the technical field of diffusers, and in particular to a conformal channel diffuser. Background Art

[0002] The function of the diffuser is to convert the dynamic pressure of the fan into static pressure, thereby reducing the speed and increasing the pressure. At the outlet of the blade diffuser, under the constraint of the blade flow channel shape, the distribution of the airflow angle does not show a trend of first increasing and then decreasing at the inlet, but rather shows an overall increasing trend along the blade height, indicating that the uneven airflow at the impeller outlet is effectively controlled by the blades. At the same time, the use of the blade diffuser reduces the overall airflow angle at the diffuser outlet, which helps to reduce the along-the-way loss of the downstream airflow.

[0003] However, the input end of the existing diffuser does not have a protective device. When the diffuser is in operation, impurities are easily introduced into the diffuser. Moreover, when the diffuser is used for a long time, impurities are accumulated on the inside of the blades, and the impurities are not easy to clean. Summary of the invention
