DW.FANS SERIES

——

DW.FANS series is a vertical HVLS energy-saving fan, which breaks the installation limitations of traditional industrial large fans and is suitable for more indoor and outdoor places that require ventilation and cooling, such as airports, high-speed railways, amusement parks, bars, restaurants, citizen squares, commercial complexes, etc.
The DW.FANS series solves the industry problem of outdoor cooling. Due to the limitations of the site and environment, general ventilation and air conditioning equipment often cannot function well outdoors. However, the DW.FANS series energy-saving fans are more suitable for ventilation and cooling equipment in this environment, which can create a comfortable feeling close to natural wind.

VFD : Vector Converter

1. Start steady : Motor vector algorithm and current suppression to achieve
2. No noise : up to 16 KHZ , no noise during speed up , slow down , and running
3. Restart : It can smooth restart when the blades not completely stopped
4. Failure protection : 25 fail-safe protections ( over current , over voltage , under voltage phase loss , overload , etc .)

Blade : Streamlined variable cross-section

1.0.059” thickness No.5052 aviation aluminum alloy plate , not break wher Impact

2.To aerodynamic equal chord length theory, the blade narrows and thins from root to tip till tail then widen, more uniform
3.17ibs per blade (24ft ) , 5 blades total 84.9 ibs , more safer

Wheel chassis:

1.It is made of 7075 aviation-grade aluminum material by CNC lathe processing + CNC precision processing technology, the shape maintains the same height, the metal streamline is complete, and the better mechanical performance of the chassis is guaranteed.
2.After CNC machining, the precision tolerance of the chassis is controlled at 100mm to ensure the precise dynamic balance of the chassis.

Connection:

The key parts are structurally connected to ensure the fan overall safety:

1.Motor and connecting rod : The motor cover and connecting rod are equipped with a suspension ring , even if the motor shaft is loose , the hangingring will snap up and down to prevent falling.
2.Chassis and petiole: The petiole and the chassis are connected by ahook-type tenon joint , the bolts are not stressed , and the overall strength is guaranteed.
3.Blade and petiole : The centrifugal force, resistance and buoyancy generatedby the rotation of the blade are transmitted to the petiole chassis through the concave-convex tenon and tenon joint connection , so as to prevent the blade from breaking due to cutting force.

Core Technology 

Blade Design:Streamline Variable Cross-Section

1. Blade design: streamlined variable cross-section

Through aerodynamic simulation analysis, applying equal chord length theory, combined with the principle of relative linear velocity, a streamline variable cross-section fan blade was developed and designed, which gradually narrowed and thinned from blade root to tip, with more balanced force, more uniform air supply, and no cavity in the center.

2. Blade Material Selection:Aviation Grade Industrial Alloy Plate

Adopting 5052H32 high grade 1.5mm aviation grade aluminum alloy motherboard, precision CNC forming, higher strength and flexibility, ensuring no fracture. Lighter and safer in weight. Each blade only weighs 6.7 kilograms (7.3 meters in diameter, excluding buffer parts), with a small number of blades and light weight, reducing motor load, extending service life, and ensuring safety and energy conservation.

3. Blade Connection - Multi Point Riveting Process

16 high-strength steel core rivets are separated and riveted up and down (a single rivet can withstand 1500kg tension), forming independent surfaces on the upper and lower layers of the blades to withstand the strong centrifugal force when the fan is running at full speed.

Patented Buffer Structure : Efficient Fan Components

1. Shock-absorption Rubber

With high-precision coordination with the blade buffer chamber, it efficiently absorbs stress and airflow vibration from the blade, reduces motor load, and extends service life.

2.  1 ° Micro Upward

There is a precise angle limit in the buffer chamber, and the blade handle is connected to the buffer chamber to form a 1 ° micro upward movement, effectively eliminating the reverse force generated during the fan operation and forming a conical airflow, achieving no voids in the center and increasing coverage.

Patent Integrated Hub:the core of fan safety

Patent Integrated Hub

By interlocking the upper and lower pressure plates with the concave and convex steps of the blade handle, the blade handle is integrated with the hub/motor, and the overall structure is used to withstand the centrifugal force during fan operation, without any stress on all fasteners.

Patent Inner Cone Shaft Sleeve

A patent inner cone kit is installed in the center of the hub, forming a structural self-locking with the output of the inner rotor motor, which naturally expands and tightens under the action of gravity, ensuring reliable connection between the overall hub and the motor.

Safety Anti Fall Structure

Anti fall ring and inner rotor motor: connect 5 blade handles with the anti fall ring through bolts, and form a sleeve hanging with the chassis of the frame to prevent falling due to wheel hub detachment or shaft breakage;

Anti Fall Ring And Outer Rotor Motor

The anti fall ring forms a collar with the motor flange, ensuring effective hooking in the event of motor shaft breakage and ensuring safe operation.
