Abstract
An efficient air filter comprises an outer cover, filter paper and a central tube. The outer cover is made of a metal cylindrical tube. The wall of the metal cylindrical tube is provided with a plurality of oblique holes; every oblique hole penetrates the wall of the metal cylindrical tube; every oblique hole is axially intersected with the axis of the metal cylindrical tube while the included angle is smaller than 90 degrees; the metal cylindrical tube is provided with a cooling device. The air passing the oblique holes in the wall of the metal cylindrical tube is cooled by the cooling device, moisture in the air condenses, condensed water flows out of the oblique holes, the humidity of air entering the metal cylindrical tube is decreased, and the filter paper is protected from being damped. The radius from any V-shaped folding apex on the outside of the tubular filter paper to the center of the tubular filter paper is larger than or smaller than that from the adjacent V-shaped folding apex to the center of the tubular filter paper. After the efficient air filter is mounted in an air passage, an air flow gap is large, air flow drag is decreased accordingly, and filtering effect is improved further.

Summary of the invention:
The object of the present invention is to provide a kind of air-strainer efficiently, described this efficient air-strainer will solve the technical problem that in prior art, in dry type paper air cleaner, filter paper easily makes moist, causes filtering resistance to increase in humid area and season.
This efficient air-strainer of the present invention comprises outer cover, filter paper and central tube, described central tube is cylindrical tube, on the barrel of central tube, be distributed with plurality of through holes, filter paper is done after V-type folds to surround cylinder along the circumferencial direction of central tube continuously, wherein, described outer cover is made up of a metallic cylinder, the internal diameter of described metallic cylinder is greater than the external diameter of filter paper cylinder, filter paper cylinder and central tube are all positioned at metallic cylinder coaxial with metallic cylinder, the wall thickness of metallic cylinder is greater than or equal to the thickness between inner circle and cylindrical in filter paper cylinder, in the barrel of metallic cylinder, be distributed with a plurality of inclined holes, any one inclined hole all runs through the barrel of metallic cylinder, any one inclined hole axially all with the axial crossing of metallic cylinder and be the angle that is less than 90 degree, on metallic cylinder, be provided with cooling unit.
Further, described cooling unit is heat exchanger, or is arranged on the cooling medium runner on metallic cylinder, or the cooling element of semiconductor.
Further, the radial cross section area sum of a plurality of inclined holes is greater than or equal to the area of the excircle of filter paper cylinder.
Further, in the radial cross section of filter paper cylinder, the folding summit of any one V-type in filter paper outside is all greater than or less than the radius of the folding summit of its adjacent V-type to cylinder center to the radius of cylinder center.
Further, the top and bottom of cylinder are connected with respectively ring-type fixed block.
Further, described ring-type fixed block is made up of PU colloid.
Concrete, lower end and the upper end of metallic cylinder are provided with end cap, be provided with air passageways and communicate with central tube inner chamber in the end cap of upper end.
Working principle of the present invention is: the air that contains moisture arrives the excircle of filter paper cylinder after a plurality of inclined holes in metallic cylinder barrel, then enters central tube after filtering.Metallic cylinder is cooled by the cooling device, the air that contains moisture when the inclined hole with metallic cylinder heat exchange, temperature reduction, airborne hydrogenesis, flow out along inclined hole, the airborne humidity entering in metallic cylinder is reduced, and has avoided filter paper to make moist.In addition, the folding summit of any one V-type in filter paper outside is all greater than or less than the radius of the folding summit of its adjacent V-type to cylinder center to the radius of cylinder center, therefore air-strainer is installed to after air passageways efficiently, air flow gap is large, thereby reduce air flow resistance, improved filtering effect.
The present invention and prior art are compared, and its effect is actively with obvious.The present invention in the arranged outside of cylindric filter paper a metallic cylinder, utilize the cooling air through inclined hole in metal cylinder barrel of cooling unit, make to flow out along inclined hole after airborne hydrogenesis, reduced the humidity of the air entering in metallic cylinder, avoided filter paper to make moist.In addition, change the folding method of filter paper, the folding summit of any one V-type in cylindric filter paper outside is all greater than or less than the radius of the folding summit of its adjacent V-type to cylinder center to the radius of cylinder center, air-strainer is installed to after air passageways efficiently, air flow gap is large, thereby reduce air flow resistance, further improved filtering effect.
