Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary instruments for condenser equipment, and particularly relates to an evaporative condenser with a noise reduction structure. Background Art

[0002] An evaporative condenser is a heat exchange device used for cooling cold storages, which is composed of components such as a fan, a condensing coil, heat exchange fins, a box body, etc. Since one or more axial fans are installed inside the evaporative condenser, and noise is bound to be generated during high-speed air extraction operation. Even if the fan is inside the box body, without noise reduction treatment on the box body, relatively loud noise can still be heard outside. Moreover, when the axial fan operates at high speed, the exhaust duct of the condenser will vibrate due to friction with the discharged air, generating noise. Therefore, those skilled in the art propose an evaporative condenser with a noise reduction structure here. Content of the Utility Model

[0025] It includes a condenser device 1, and an air outlet silencer 2 is arranged at the position of the top air outlet port of the condenser device 1; wherein, the condenser device 1 includes a condenser box 19, side plates 11 fixed on the left and right sides of the condenser box 19, and a front side plate 14 and a rear side plate 18 fixed on the front and rear side walls of the condenser box 19, and a front side air inlet 13 and a rear side air inlet 17 are respectively arranged inside the front side plate 14 and the rear side plate 18; an axial flow fan 15 is fixed in the inner cavity of the condenser box 19, heat exchange fins 12 are also installed at the bottom of the inner cavity of the condenser box 19 and below the axial flow fan 15, and a top plate 16 is fixed on the top surface of the condenser box 19; on one side where the side plates 11 are close to each other, the bottom surface of the top plate 16, and the surfaces where the front side plate 14 and the rear side plate 18 are close to each other, a piece of sound-absorbing cotton 110 is fixed by an adhesive;

[0026] The air outlet silencer 2 includes an exhaust duct 21, an outer sound-absorbing cotton 24 sleeved on the outer circle of the exhaust duct 21, and an inner sound-absorbing cotton 23 sleeved on the inner circle of the exhaust duct 21. 8-12 strip-shaped air outlet slots 22 are provided on the peripheral side walls of the exhaust duct 21, the inner sound-absorbing cotton 23 and the outer sound-absorbing cotton 24.

[0027] Rectangular through holes are provided in the sound-absorbing cotton 110 on the inner surfaces of the front side plate 14 and the rear side plate 18 for allowing the front side air inlet 13 and the rear side air inlet 17 to circulate air into the condenser box body 19. Air outlet holes 111 are provided in the top plate 16 and the sound-absorbing cotton 110 on the bottom surface of the top plate 16 for exhausting the air inside the condenser box body 19.

[0028] The bottom port edge of the exhaust duct 21 is fixedly connected to the inner cavity side wall of the air outlet hole 111. The strip-shaped air outlet slots 22 are arranged in a circular array with the central axis of the exhaust duct 21 as the reference point.
