Abstract

PURPOSE: To obtain the silencer for a vortex flow fan with sufficient pressure seal at a low cost by using thin metal plates.
CONSTITUTION: In constituting this silencer, elastic bodies 13 are attached onto the bent sides 14 of a partition plate, and the bent side 14 is positioned at prescribed position, and the bent side 14 is spot-welded to a base plate 1. Then intermediate pieces 22 and 23 are welded to the base plate 1 and the partition plate 3. Further, elastic bodies 13 are attached onto the outer sides 9 and 10, and the outer sides 9 and 10 are opposed to the base plate 1, and each spot-welded at the position 12. Lastly, each throttle plate 4, 5, 6, 7 is continuously welded with the partition plate 3, base plate 1, and a groove plate 2. A hole 19 is connected with the suction port (not shown in the figure) of a vortex flow fan, and a hole 20 is connected with the discharge port, and furthermore, a hole 17 is connected with a suction pipe not shown in the figure, and a hole 18 is connected with a discharge pipe. Thus, using thin metal plates, the silencer of the vortex flow fan with sufficient pressure seal can be obtained at a low cost.
