How to make a deflector
TO deflectors refers to a group of aerodynamic devices,the principle of which is based on the deviation of the flow of gases, liquids, solids and even light waves. Thus, the deflector can be used to enhance the exhaust of air from the room. Automobile deflectors are designed mainly to protect against damage to body parts - the hood, headlights, hatch, windows, rear doors.
Instructions
1
If the car wind deflectors are on sale ina huge assortment, then the deflector for a cellar or a garage is likely to have to do by yourself. The traditional material for the exhaust pipes and ventilation is galvanized iron. It is necessary to ensure that the diameter of the deflector is 2.5 times larger than the diameter of the pipe.
2
It will be a trumpet with threecones in the upper part, two of which will be truncated, connected by spacers. Try to make the cones at the base have an acute angle of 25 degrees.
3
The two upper cones are made with such a calculation,so that the top has a slight overlap for bending over the second cone. This way you prevent water from flowing into the deflector. The design of the deflector is secured by the rivets and clamps, which are fixed to the pipe by a yoke.
4
Lower the lower part of the exhaust pipe belowthe level of the ceiling is approximately 20 cm. At the same time, the bottom of the supply pipe should not be more than half a meter from the floor and be as far as possible from the exhaust pipe. The top of the supply pipe should also be installed above the roof level by half a meter, which will ensure effective wind blowing. If you do everything correctly, the thrust in the pipe at a wind speed of 6 m / sec will increase two to three times.
5
Installation of the deflector (spoiler) on the hoodThe car is made in order to protect it from minor damage. The deflector purchased in the store is installed using a Phillips screwdriver for drilling holes in the hood without drilling. First, at the deflector attachment points, remove all the fixing elements of the hood insulation, then make an approximate fitting in the installation site.
6
Remove the protective film from the deflector, andInstall the device in place of the attachment and fix it with a special adhesive. The brackets are fixed with self-tapping screws and then applied to them with an anti-corrosion coating. After that, the hood insulation elements can be replaced.
