Abstract
The utility model discloses a cooling fan of an air conditioner outdoor unit. The cooling fan comprises a fan shell (1), an electromotor (2) and fan blades (3), wherein the electromotor (2) is fixed on the fan shell (1); the fan blades (3) are fixed on a blade frame (4); and the blade frame (4) is fixed on a main shaft of the electromotor (2). Sawtooth-shaped notches (31) are formed in the fan blades (3), so that a noise reduction effect can be well achieved, and the fan is simple in structure and relatively low in manufacturing cost.
Description
Technical field:
The utility model relates to the blower fan technical field, more specifically to a kind of air conditioner outdoor machine group cooling blower.
Background technique:
Along with people's is increasingly high to environmental requirement; People have also proposed more highland requirement to the noise that reduces of blower fan; Because central air-conditioner generally all is installed in densely populated places such as office building, office building; Therefore the noise of the outdoor unit cooling blower of central air-conditioner must be little, and existing air conditioner outdoor machine group cooling blower generally adopts fan to be equipped with special-purpose muffling device or on the structure of blower fan, improves the effect that reduces noise to reach, but adopting aforesaid way to reduce noise makes that its cost is very high; And adopt aforesaid way also can make the structure of blower too fat to move, huge, this gives and installs and carrying has brought very big inconvenience.
The model utility content:
The purpose of the utility model is exactly the deficiency to existing technology, and a kind of air conditioner outdoor machine group cooling blower is provided, and it can reach the effect that reduces noise well, and makes the simple in structure of blower fan, and manufacture cost is also lower simultaneously.
The technological solution of the utility model is following:
Air conditioner outdoor machine group cooling blower comprises Blower Housing, motor and fan blade, and motor is fixed on the Blower Housing, and fan blade is fixed on the vane frame, and vane frame is fixed on the main shaft of motor, forms jagged breach on the fan blade.
Be fixed with the blower fan guard shield on the exhaust outlet of said Blower Housing.
Said fan blade is fixed on the vane frame through rivet.
Said motor is fixed on the grillage, and grillage is fixed on the Blower Housing.
The beneficial effect of the utility model is:
It improves blade, can reach good erasure effect, and its is relatively simple for structure, can not give to install and carrying made troubles, and cost is also lower simultaneously.
Description of drawings:
Fig. 1 is the structural representation of the utility model
Fig. 2 is equipped with the structural representation of guard shield for the utility model
Fig. 3 is the sectional view of the utility model
Among the figure: 1, Blower Housing; 2, motor; 3, fan blade; 4, vane frame; 5, blower fan guard shield; 21, grillage; 31, breach.
Embodiment:
Embodiment: see shown in Fig. 1 to 3; Air conditioner outdoor machine group cooling blower; Comprise Blower Housing 1, motor 2 and fan blade 3, motor 2 is fixed on the Blower Housing 1, and fan blade 3 is fixed on the vane frame 4; Vane frame 4 is fixed on the main shaft of motor 2, forms jagged breach 31 on the fan blade 3.
Be fixed with blower fan guard shield 5 on the exhaust outlet of said Blower Housing 1.
Said fan blade 3 is fixed on the vane frame 4 through rivet.
Said motor 2 is fixed on the grillage 21, and grillage 21 is fixed on the Blower Housing 1.
Working principle: form jagged breach 31 on the fan blade 3 of the utility model, these breach 31 make that fan blade 3 rear side ground are stressed littler, and the vibration of fan blade 3 is littler, can be so that the utility model reaches the effect that well reduces noise.
