Embodiment Construction
[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0024] Figure 1 to Figure 5 As shown, a two-dimensional array duct fan, the duct fan includes an air duct 30, a motor 10, a motor base 20, a fan body 50, and an air duct partition 60, and the air duct 30 includes a first air duct 301 and a second air duct 301. The air cylinder 302, the axis of the first air cylinder 301 intersects the axis of the second air cylinder 302, the inner sections of the first air cylinder 301 and the second air cylinder 301 are square, and the air duct partition 60 divides the first air duct 302 into several sub-air ducts 3011 longitudinally and transversely, and the mo...

A two-dimensional array pipeline fan comprises an air drum, a motor, a motor base, a fan body and air channel partition plates. The air drum comprises a first air drum and a second air drum, the axes of the first air drum and the second air drum intersect, inner sections of the first air drum and the second air drum are square, the air channel partition plates divide the first air drum into a plurality of auxiliary air channels longitudinally and transversely, the motor base is fixedly arranged outside an intersection position of the first air drum and the second air drum, the motor base is provided with shaft through holes corresponding to the auxiliary air channels, the motor is arranged on the motor base, a motor shaft of the motor penetrates through the shaft through holes to extend into the corresponding auxiliary air channels, and the fan body is arranged at the front end of the motor shaft and in the auxiliary air channels. The motor is externally arranged, does not cover flow diameter of the air channels, air channel use rate and air supplying efficiency are improved, air resistance is small, maintenance is convenient, energy is saved, heat produced in working of the motor does not affect a pipeline working medium, an air flow evenness degree is high in the air channels, speed difference among sub-air-flows is reduced, air supplying noise is remarkably reduced, and air supplement can not stop completely due to damage of a single motor.
Description
technical field [0001] The invention belongs to the field of fans, and in particular relates to an axial-flow pipeline fan. Background technique [0002] Same invention date as the present invention, same inventor, invention name: a pipeline fan, a relay pipeline fan belonging to the axial flow type is given, and the curved tube air cylinder body of the pipeline fan is a square tube or a circle Tube, when the body of the curved tube fan cylinder is taken as a square tube and a single fan body works, the airflow conveyed in the fan cylinder is a single airflow, because the square inner cavity of the fan cylinder and the fan body of the curved tube fan cylinder The outline is not completely matched, and there is more space at the four corners. When the fan is working, there is a speed difference between this part of the airflow and the airflow at other positions in the fan cylinder. This difference will increase the disturbance of the airflow in the fan cylinder, causing noise...
