Specifically, the purification filter unit 220 according to the present embodiment includes an adsorption filter 224 for adsorbing foreign substances from the inflow air, a water removal filter 225 for removing moisture from the air passing through the adsorption filter 224, and moisture. It may include a fiber filter 226 for removing the foreign matter by the particle diameter from the air passing through the removal filter 225.

Such a purification filter unit 220 is to increase the purification efficiency while preventing the filter blockage by mixing the separation by adsorption, moisture removal and particle size.

In the present invention, an example of the adsorption filter 224 is illustrated in FIG. 8.

Adsorption filter 224 of the present embodiment, as shown in Figure 8 and the outer frame 224-1 and a plurality of elastic material string 224-2 mounted on the upper end of the inner frame (224-1) and the inner periphery; Adsorbed plate formed on the inner circumference of the outer frame 224-1 to form a plurality of inclined gradients in the lower portion of the string 224-2 and formed so that a flow path 224-4 is formed, and an adsorption coating layer of an adhesive material formed on an upper surface thereof. 224-3).

Air flowing from the outside passes through the string 224-2 in the adsorption filter 224. As shown in FIG. 8, the string 224-2 is an elastic material and the string ( 224-2) is a vibration is generated and such vibration energy is to be imposed on the flowing air.

The air g1 to which the vibration energy is applied is in an excited state to facilitate the separation of foreign matter from the air. Air g1 in this state flows on the upper surface of the adsorption plate 224-3 on which the adhesive coating layer of adhesive material is formed, and the air g2 in which the foreign matter such as fine dust has been removed by adsorption by the adsorption coating layer flows through Through 224-4.

That is, the adsorption filter 224 of the present embodiment is to increase the separation efficiency of the foreign matter by adsorption from the air by applying vibration energy to the air to be in an excited state.

As such, the air passing through the adsorption filter 224 passes through the water removal filter 225 formed at the lower portion thereof so that the water mixed in the air is removed. The reason for removing the water is to express the effect of dehumidification. Of course, it is for controlling the fiber filter 226 at the rear end deteriorated by moisture exposure.

Here, the water removal filter 225 may be applied with various known techniques. In the present invention, in the case of the water removal filter of the conventionally known material, the water is removed by adsorbing moisture from the air. In order to solve an unexpected problem, the structure of the embodiment illustrated in FIGS. 6 and 7 may be applied.

As shown in FIG. 6, the water removal filter 225 of the present embodiment is a heat conductive frame 2252 of a thermally conductive material, and a mesh body 225-12 mounted inside the heat radiating frame 225-2 and having a gap formed therein. ) And a mesh portion 225-1 including the carbon nanotube coating layer 225-11 applied on the manganese body 225-12.

As shown in the figure, air (g) passing through the adsorption filter 224 passes through the mesh portion 225-1, and moisture is introduced from the air (g) by the carbon nanotube coating layer 225-11. Only the air g1 from which the moisture is removed from the air g is controlled to pass through the mesh portion 225-1.

In the carbon nanotube coating layer 225-11, carbon nanotubes have a hydrophobic property, and the coating layer 225-11 has a hydrophobic surface by the carbon nanotubes so that water is introduced from the air (g). This is to be controlled.

In addition, the carbon nanotube has a high thermal conductivity, in particular, when hot air is introduced in summer, etc., so that the heat dissipation function is also performed in addition to the moisture blocking function from the air, as shown in FIG. The carbon nanotube coating layer 225-11 is absorbed and transferred to the heat dissipation frame 225-2, thereby dissipating heat (H) from the heat dissipation frame 225-2 to the outside. As the 225-11 absorbs heat from the air g, the gaseous moisture is liquefied, and the liquefied water is naturally filtered by the carbon nanotube coating layer 225-11.

The heat dissipation frame 225-2 is made of a material having high thermal conductivity, such that aluminum is applied to dissipate heat (H) transmitted by the carbon nanotube coating layer 225-11 to the outside, thereby reintroducing heat into the air. To be controlled.

The carbon nanotube solution forming the carbon nanotube coating layer 225-11 is a mixture of carbon nanotubes in various known solvents, and a known additive such as a dispersant may be added to improve the dispersibility of the carbon nanotubes. .

For example, a hydrophobic surfactant may be applied as a solvent, such as POLYOXYETHYLENE STEARYL ETHER DERIVATIVES, SORBITAN FATTY ACID ESTER DERIVATIVES, POLYOXYETHYLENE OLEYLAMINE DERIVATIVES Etc. may be applied.

The manganese body 225-12 is formed such that a gap is formed such that air (g1) from which moisture is removed by the carbon nanotube coating layer 225-11 flows downward through the gap. In the case of the main body 225-12, various known materials may be applied, and thus detailed description thereof will be omitted.

In addition, in the present embodiment, as shown in FIG. 7, the heat dissipation frame 225-2 has a tubular shape having a space formed therein, and a flow hole 225 at one side of the inner circumference of the heat dissipation frame 225-2. -21 is formed, and the mesh portion 225-1 is mounted such that a downward slope gradient α is formed in the direction of the flow hole 225-21 at the inner circumference of the heat dissipation frame 225-2. Give an example.

That is, as shown in the drawing, the net portion 225-1 is mounted on the inner circumference of the heat dissipation frame 225-2 such that an inclined gradient α is formed, and the end of the net portion 225-1 is a flow hole 225-21. Moisture (W) separated from the air by the carbon nanotube coating layer (225-11) flows along the gradient of the net portion 225-1, so as to be softly connected to the heat radiation frame (225-21). 225-2) to be stored inside.

Moisture (W) separated from the air by the carbon nanotube coating layer (225-11) there is a flow of air hitting the net 225-1 continuously, so that the net portion 225-1 to form a gradient gradient by such a blow Ride) to flow in the downward direction to be stored in the heat radiation frame (225-2).

Although not shown in the drawing, the heat dissipation frame 225-2 should have a discharge line formed to discharge the moisture stored in the heat dissipation frame 225-2 to the outside through the discharge line.
