Filed: 2020-05-22
Abstract: To provide a blower capable of reducing the noise of a fan and capable of improving efficiency of the fan.SOLUTION: Outside a guide part 24 in the fan radial direction, a communication passage 24b is formed for communicating an upstream space 12a with a gap 201a between a fan ring part 201 and the guide part 24. The fan ring part 201 of a side plate 20 is positioned further on the outside in the fan radial direction than an innermost peripheral part 242 of the guide part 24. Therefore, a reverse flow air flow shown by an arrow F2r merges with an air flow of the communication passage 24b, and merges with a main flow by passing through the gap 201a between the fan ring part 201 and the guide part 24 as shown by an arrow Fo. Thereby, in a reverse flow outlet portion in which the reverse flow air merges with the main flow, an intersection angle between the direction of the reverse flow air flow and the direction of the main flow can be reduced. As a result, the noise of a fan 16 can be reduced and the efficiency of the fan 16 can be improved.SELECTED DRAWING: Figure 4
