How to make a fanless fan

With the onset of heat, we immediately recall all kinds of devices for air freshening. And one of these devices is a simple fan. Its design is an engine and a multi-blade impeller mounted on its shaft. Despite the simplicity of the design, the fan has a number of significant drawbacks. It is very noisy, dust constantly settles on it, which later swells around the room. In addition, they are quite dangerous, with the fan running, the child may accidentally stick his hand under the protective grill and get injured.

All these shortcomings are devoid of a bladeless fan. This is truly an innovative technology.

Necessary materials:

• Small pieces of PVC pipes (diameter 90, 125.150mm);
• Glue moment (any other quick-drying glue);
• A small piece of plexiglass or plexiglass (preferably blue);
• Server cooler YW880 (preferred frame width 60mm);
• Spray can with white paint;
• A piece of soft metal mesh (mesh size 10mm);
• Soldering materials, screws and thermal cages;
• Rheostatic speed control board and toggle switch;
• LED strip (approximately 50cm);
• Insulating tape;
• Power supply for 12V.

Work process

We cut from the PVC pipe with a diameter of 150 mm a portion equal to 10 cm. We process the edges with sandpaper. Next, we select a container for our pipe segment. Cut it off and fix it with glue.

We cut off from the PVC pipe with a diameter of 125 mm a portion equal to 9 cm. With a pipe with a diameter of 90 mm, we do the same, cut 13 cm. The last section will serve as the base of the fan. And so we cut off its edges according to the circumference of the largest part.

This part is drilled with a 60 mm diameter crown. Next, glue it to our base. To the middle PVC segment, it is necessary to glue a Plexiglas plug along the contour. The plug must be a ring. From the outside, paint it white.

Along the contour of the inner part of a large segment, we glue the LED strip, we bring the wires to the base. We glue all the parts.

Now we insert the cooler into the base and bring all the wiring down. On the lower border of our stand, we make a through hole with a crown. We cover them with pieces of mesh, gluing from the inside.

Wiring from the cooler and tape, connect to the toggle switch. We drill a hole for it in the base. Power wires lead out. Now they can be connected to the power supply. The fan is ready, you can enjoy the flow of pleasant cool air.
