Abstract
The utility model provides a combination type axial-flow fan of the field of machines. The structure is characterized in that the circular cylindrical or square cylindrical fan case is provided with a plurality of air deflectors with incline, an air channel is formed between two air deflectors. Each air channel is coaxially provided with blades with the same number with the air channel, and a fan shaft is fixedly connected with a motor and the fan case.
Description
The utility model provides the blower fan of mechanical field.
Axial-flow blower, main working parts are fans and stream guidance fan housing, and every line shaft only is with fans, for example an electric fan usually.The blower fan of this structure can be made into bigger diameter, and performance characteristic is, air quantity is big, and blast is low.Be suitable for for narrow and small ventilation occasion.
The purpose of this utility model is to provide a kind of and can adapt to the built-up shaft flow fan that narrow and small occasion is ventilated.
Realize that scheme of the present utility model is, two above fans are installed on a fan shaft, constitute combination fan, combination fan is installed in the air channel.
Connect the built-up shaft flow fan that the utility model scheme is made, on fan shaft, several fans can be installed, and that the diameter of fan can be done is less, so just, can carry out ventilation operation to long and narrow zone, thereby realize the ventilating machinary thin typeization, help using design, enlarge the application area of ventilating product and the application performance of raising product.
Elaborate below in conjunction with accompanying drawing:
Fig. 1 is the utility model structural drawing
Among Fig. 1,1 is Fan casing, can be garden tubular or square tube shape, at one End is equipped with motor 2, and motor 2 is connected with fan shaft 3, and the other end is fixed on On the bearing block 4, the interval is equipped with fan leaf 5 on fan shaft 3. At blower fan In the shell 1, the wind deflector 6 consistent with fan leaf quantity is installed, wind deflector 6 is flat Face direction and Fan casing 1 horizontal sides direction are angled. At two wind deflectors 6 Between, form air channel 7.
Air channel one end air intake, other end air-out.
Embodiment's explanation
Press the utility model scheme and make the air conditioner blower fan, blower fan boundary dimension is long 60cm, wide 10cm, fans diameter 9cm.Blade quantity is 6, and necessary electromotor is 50 watts.
The results showed that this structure blower fan can reach the ventilation of technical requirements, and the shared space width of complete machine only be 10cm fully under the less situation of flabellum diameter.
Air conditioner heat exchanger according to the manufacturing of the utility model blower fan has been realized ultra-thinization.
