TH137C3 - Motor cooling and sound absorption system - Google Patents

Abstract

The motor cooling and sound-absorbing system is incorporated by a enclosure (10) that forms a filling compartment (13) surrounding the motor (11), the motor shaft (12) (11) is also attached. The fan (40) is positioned in the compartment (38) created by the cavity (36) cut into the foam block (35), the fan (40) will suck air into the compartment (13). ), And this air is then directed through the motor (11) to cool it down. Air will exit from the fan (40), which is typically trapped by The radius direction is directed to the angled surface (37) of the cavity (36) of the foam block (35). The air is then taken in. Surface Angled (37) and angled surface (42) of the positioned fork plate (19) Above the foam block (35), the passage of the spreader (41) reduces the speed of the Air to assist the foam block (35) to absorb the noise generated by it, in At the same time, it reduces the pressure at the fan outlet (40) to increase the air flow for cooling. Down through the motor (11), then air passes from the diffuser pass path (41) to the elongated groove (26) formed in the lower part of the hood (10 )

Claims (9)

1. Enhanced damped sound and cooling system for a device which It consists of a hood, a motor inside a enclosure whereby the motor rotates the protruding shaft. Along the axis that have been adjusted so that it is connected at one end. To one device, a fan installed by the other end of the shaft, the air inlet area is arranged. Made in such a hood, the air-emitting area created in the hood by Where the fan is introduced into the hood through the air inlet area And through the said motor and diffusion device, where the diffuser receives air From the fan and reduce the air velocity before it reaches the air outlet through an area for Released in such a way that the air flow through the motor is increased, at the same time The noise of the air and the motor will be reduced. 2. A system corresponding to claim 1, which follows, consists of sound-absorbing materials that surround it. Around the fan where the fan directs air towards the sound-absorbing material to Will reduce the noise further 3. System corresponding to claim 2, where the diffuser is integrated by a line Passage between the fan and the discharge area, with one side of the pass It is bounded by the surface of the sound absorbing material. 4. A system corresponding to claim 3, which in the following sequence consists of designated choke plates. Positioned above the sound absorbing material, where the shock plate has a surface that produces a different side. Of the pass 5. System corresponding to claim 4, which, in the order of, consists of an air vent. That was created between the pass through and the release area, where the surface Of the sound-absorbing material and the surface of the said shock-plates are diverted As the path extends to the said air port 6. System complies with claim 5, where the upper surface of the sound absorbing material is defined. Boundary to the bottom surface of the vented port. 7. System corresponding to claim 1, which, in the order of, consists of such sound-absorbing materials. There is a hollow formed inside by which the fan is introduced into the cavity. 8. A system complying with claim 7, where such a covering is incorporated by a correct shock plate. Positioned above the sound-absorbing material, where the shock plate and the cavity are. In such sound-absorbing materials 9. System corresponding to claim 8, where the cavity in the said sound-absorbing material represents A surface that is angled along the perimeter that is positioned in the fan edge radius direction 1. 0. The system complies with claim 9, where the shock plate has an angled surface according to The perimeter above the fan and opposite the angled surface of the perimeter. Of the cavity in the aforementioned sound-absorbing material and is spaced from the angled surface along the Perimeter
