Deflectors include a group of aerodynamic devices, the principle of which is based on the deflection of the flow of gases, liquids, bulk solids and even light waves. So, the deflector can be used to enhance the air extraction from the room. Automotive deflectors are designed mainly to protect against damage to body elements - hood, headlights, sunroof, windows, rear doors.
Instructions
Step 1
If car deflectors are on sale in a huge assortment, then a deflector for a cellar or garage will most likely have to be done by hand. The traditional material for exhaust pipes and ventilation is galvanized iron. It is imperative to provide that the diameter of the deflector is 2.5 times the diameter of the pipe.
Step 2
It will be a pipe with three cones in the upper part, two of which will be truncated, interconnected by spacers. Try to keep the cones at the base at an acute angle of 25 degrees.
Step 3
Make the two upper cones so that the upper one has a slight overlap for bending over the second cone. This will prevent water from flowing into the deflector. The deflector structure is fastened with blind rivets and brackets, which are attached to the pipe with a clamp.
Step 4
Place the lower part of the exhaust pipe below the ceiling level by about 20 cm. The bottom of the supply pipe should not be higher than half a meter from the floor and be as far from the exhaust pipe as possible. The top of the inlet pipe should also be installed above the roof level by half a meter, which will provide effective wind blowing. If you do everything correctly, then the thrust in the pipe at a wind speed of 6 m / s will increase two to three times.
Step 5
on the hood of the car is made in order to protect it from minor damage. Install the deflector purchased from the store using a Phillips screwdriver without drilling special holes in the hood. First, at the points of attachment of the deflector, remove all the fixing elements of the hood insulation, then make an approximate fitting at the installation site.
Step 6
Remove the protective film from the deflector, and install the device in the place of attachment and fix it with special glue. The brackets are fixed with self-tapping screws, followed by applying an anti-corrosion coating to them. After that, the hood insulation elements can be replaced.
