Complete Configuration of Air Conditioning Aids

1 is a view showing the overall configuration of the automotive heating and cooling auxiliary apparatus according to an embodiment of the present invention.

Referring to FIG. 1, the air-conditioning assistance device of the present invention includes at least one air inlet pipe 100 having an air purifier 110 mounted thereon, and three pipes branching from one end of the air inlet pipe 100. It may be configured to include a branch pipe 200, the second branch pipe 300, the third branch pipe (400).

The air inlet pipe 100 according to an embodiment of the present invention introduces external air. That is, when the vehicle is driven or stopped, air outside the vehicle may be introduced into the air inlet pipe 100. One end of the air inlet pipe 100, that is, the end into which air is introduced, may be formed in a trumpet shape to facilitate air inflow. On the other hand, at least a portion of the air inlet pipe 100 is equipped with an air purification apparatus 110. The air purifier 110 is a purifier that operates by performing a catalytic reaction at a predetermined temperature or higher, preferably at 250 ° C or higher. According to one embodiment of the present invention, LMR (Light Metal Reactor) may be used as the air purification device (110). A detailed description of the operation of the air purification device 110 will be described later. The first branch pipe 200, the second branch pipe 300, and the third branch pipe of both ends of the air inlet pipe 100 equipped with the air purification device 110, that is, the air inlet pipe 100 ( The valve 120 may be formed at the end connected to the 400. The valve 120 is one or more of the air inlet pipe 100, the first branch pipe 200, the second branch pipe 300 or the third branch pipe 400 under the control of a controller (not shown). It performs the function of connecting or closing the pipe.

The first branch pipe 200 according to an embodiment of the present invention is a pipe through which the air purified by the air purification apparatus 110 flows into the air inlet pipe 100 and is discharged from the first branch pipe 200. The air exhausted at the end can be used as heater heat in the motor vehicle. As described above, since the air purifier 110 operates at a predetermined temperature or more, the air that has passed through the air purifier 110 has a temperature of a predetermined value or more. Therefore, the air exiting the air purifier 110 can be used as the heater heat. However, the air exiting the air purifier 110 may be cooled (for example, in the process of flowing into the first branch pipe 200 or the process of passing through the first branch pipe 200) for various reasons. In this case, the air exiting the first branch pipe 200 may not be used as a heater heat. Accordingly, at least a part of the first branch pipe 200 may be formed adjacent to the engine 500 of the vehicle as a means for heating the cooled air again. Alternatively, a coolant inflow pipe through which the coolant derived from the engine 500 flows may be formed in at least a portion of the first branch pipe 200. That is, the air passing through the first branch pipe 200 is heated by heat exchange with the heat of the engine 500 itself or cooling water derived from the engine 500, and then exits the first branch pipe 200. It can also be used as a heater heat. The connection or closing between the first branch pipe 200 and the air inlet pipe 100 may be realized by the valve 120. Specifically, when the vehicle indoor heating blower switch is in the on state, the valve 120 connects the first branch pipe 200 to the air inlet pipe 100 according to the control of the controller. ) May close the first branch pipe 200 and the air inlet pipe 100.

Next, the second branch pipe 300 according to an embodiment of the present invention performs a function of transferring the air passing through the air purification device 110 to the vehicle interior. The air passing through the air purification device 110 may be cooled to a certain degree while passing through the second branch pipe 300 at room temperature or higher, and the air may be introduced into the vehicle interior as it is. Connection or closing of the second branch pipe 300 and the air inlet pipe 100 may also be realized by the valve 120. That is, when the external air inlet switch of the vehicle interior is turned on, the valve 120 connects the second branch pipe 300 to the air inlet pipe 100 under the control of the controller. The second branch pipe 300 and the air inlet pipe 100 may be closed.

The third branch pipe 400 according to an embodiment of the present invention is also a pipe that serves to discharge the air flowing out of the air inlet pipe 100. Air discharged from the end of the third branch pipe 400 may be used as air conditioning air in the vehicle. The air that has passed through the air purifier 110 may have a temperature of a predetermined value or more or a temperature of room temperature or more. Such air may be unsuitable to be used as air conditioner air. Therefore, at least a part of the third branch pipe 400 may be provided with means for cooling the air passing through the third branch pipe 400. As an example, as shown in FIG. 1, at least a portion of the third branch pipe 400 may have a refrigerant inlet pipe 410 through which the compressed refrigerant in the vehicle passes. Accordingly, the air purified by the air purifier 110 is cooled by heat exchange with the compressed refrigerant while passing through the third branch pipe 400, and then exits the third branch pipe 400 as air conditioner air. The state can be used. Connection or closing between the third branch pipe 400 and the air inlet pipe 100 may also be selectively implemented by the valve 120. That is, when the automotive air conditioner blower switch is turned on, the valve 120 connects the third branch pipe 400 to the air inlet pipe 100 under the control of the controller. The three branch pipe 400 and the air inlet pipe 100 may be closed. On the other hand, the refrigerant flow into the refrigerant inlet pipe 410 may also be controlled by a separate valve (not shown). That is, the valve is opened only when the vehicle interior cooling blower switch is turned on, so that the coolant may flow into the refrigerant inlet pipe 410.

Hereinafter, the detailed configuration and operation principle of the air purification device 110 will be described in detail.

Air filter

The air purifying apparatus in the present invention is based on the air purifying carrier disclosed in Korean Patent Application No. 2009-0036439 ("Support Structure Using Inorganic Membrane and Method for Producing the Carrier") filed by the present applicant. The present applicant can significantly reduce the time required to rise to a temperature capable of causing a catalytic reaction in the air purification device because the air purification carrier described in the above application, which is an improvement of the conventional air purification carrier, that is, a light metal and has excellent thermal conductivity. An air purification carrier to which aluminum is applied will be referred to as LMR (Light Metal Reactor).

An inorganic film is applied to the air purifier 110, which will be described below.

The inorganic film used for the air purification device 110 may be manufactured using a conductive metal. As an example, aluminum, which is a light metal, may be used. The manufacturing process of such an inorganic film is described as follows. In the following description, the conductive metal used for the production of the inorganic film will be described with an example of aluminum. First, a hollow cylindrical aluminum tube is prepared, and the inside and the outside are degreased. Thereafter, metal oxides contained in aluminum are removed by etching or the like, and then immersed in a weakly acidic solution to remove insoluble materials. Next, an aluminum wire or an aluminum wire is disposed in the center of the aluminum tube to apply a cathode current, and an anode current is applied to the aluminum tube. In addition, the electrolyte is circulated inside the aluminum tube so that the anodization reaction may occur as a whole. Hydrogen is generated around the aluminum wire or wire to which the cathode current is applied by the anodic oxidation reaction, and oxygen is generated to the aluminum tube to which the anode current is applied. This oxygen reacts with the aluminum tube, whereby alumina, which is aluminum oxide, is gradually deposited on the inner wall of the aluminum tube, which is formed as an alumina film.

During the anodic oxidation reaction, the electrolyte solution dissolves the formed alumina film finely. When the dissolution rate and the growth rate of the alumina film are balanced, uniform pores having a diameter of about 10 to 150 μm are formed in the alumina film. Will be formed. That is, through the anodic oxidation reaction, a thick alumina film having uniform pores can be formed on the inner wall of the aluminum tube, and the porous aluminum film can function as an inorganic film applied to the air purification device 110.

Hereinafter, the carrier as the air purification device 110 will be described using the inorganic film obtained according to the above-described method.

Referring to the manufacturing process of the carrier used as the air purification apparatus 110 as follows. First, a catalyst layer is formed on an inner wall and an outer wall of an inorganic film formed as an alumina film prepared according to the above process by supporting a catalyst mother liquid of a noble metal series having an active gas reaction. In this case, the catalyst layer may be formed by supporting a catalyst mother liquid such as a mixture solution of platinum or rhodium. This will be described in more detail below.

Thereafter, it is calcined at 450 ° C. for 12 hours under air flow to grow a crystal structure.

Since the carrier is prepared in the form of a thin film on a metal substrate, the thermal conductivity of the carrier can be easily reached at a high temperature compared to a ceramic having a low heat capacity, and thus, various advantages that can be obtained at a high temperature can be obtained. Can be maximized.

On the other hand, in such an inorganic membrane, since the catalyst layer maintains the bond of the molecular step to the substrate, it is very resistant to physical impact.

In the above, as the metal used to form the inorganic layer, aluminum has been described as an example. However, the present invention is not limited thereto, and any metal capable of forming a metal oxide such as titanium or zirconium may be used.

On the other hand, the carrier used as the air purification device 110 may be formed in the following shape.

Referring to FIG. 2, the carrier according to another embodiment of the present invention may have a shape in which a lattice a having a shape such as a 'sieve' is formed at a predetermined height. According to this, the surface area of the inorganic film is relatively widened, and the efficiency of the gas reaction can be improved. 3 is a cross-sectional view taken along the line A-A 'of the carrier shown in FIG.

Referring to FIG. 3, the grating a is formed to be inclined at a predetermined angle with a height direction in which the carrier modules are stacked. Compared to the case where the lattice is stacked vertically with the base of the carrier module, the area in which the gaseous reactant is in contact with the inorganic membrane is increased, and in addition to the effect of increasing the reaction efficiency, the reactant passes through the carrier module. By hitting the lattice and generating turbulence or diffuse reflection, the path of the reaction material moving inside the carrier may be increased, thereby increasing the overall reaction efficiency.

3 is an enlarged view of the grating surface of FIG. 2.

Referring to FIG. 3, the surface of the lattice a may include a metal layer 610 forming a base, a transition layer 620 on which the metal constituting the metal layer 610 coexists with an oxide of the metal on the metal layer 610; The porous ceramic coating layer 630 is formed on the transition layer 620. Aluminum, titanium, or zirconium may be used as the metal constituting the metal layer 610.

Meanwhile, a platinum (Pt) or rhodium (Rh) catalyst layer may be inserted between the pores of the ceramic coating layer 630. The catalyst layer is formed by supporting the catalyst mother liquid to form a catalyst layer and then drying.

As an example, assuming that a carrier is used to purify exhaust gas, the platinum catalyst can be used to convert CO constituting the exhaust gas into CO 2 or to decompose Hydro C into H 2 O or CO 2 . On the other hand, the rhodium catalyst can be used to decompose NOx to N2.

On the other hand, Figure 4 is a view showing the manufacturing process of the inorganic film formed carrier according to another embodiment of the present invention, Figures 5 and 6 show the structure of the carrier formed with an inorganic film formed by the method disclosed in FIG. Drawing.

4 to 6, the carrier may be prepared by the following method. First, the perforation 720 is formed on the metal plate 710 by press working or the like. The perforation 720 may be similar in shape to a hole where steaming is removed from the kettle lid. A metal foam 730 having a 'sieve' shape is formed under the metal plate 710 on which the perforations 720 are formed to filter impurities such as dust contained in the outside air.

After the perforation 720 is formed, the carrier structure is anodized to form an inorganic membrane, and a catalyst layer is formed on the inner and outer walls of the inorganic membrane by supporting a catalyst mother liquid having a noble metal-based activity. This is the same as the manufacturing process of the carrier described above.

Meanwhile, the carrier thus formed is rolled into a spiral form to form a cylindrical carrier structure. The carrier structure thus prepared is disclosed in FIGS. 5 and 6.

The reaction target material (outer air) proceeds perpendicularly to the cylindrical carrier, that is, through a circular cross section, and passes through a number of perforations 720 in the process. The reaction target material entering the perforation 720 is filtered by impurities such as dust by the lattice structure of the metal foam 730 formed under the metal plate 710, and only gas passes therethrough. In general, the outside air belonging to the turbulent series has a complicated flow of the streamline, so that the harmful air contained in the outside air reacts with the catalyst layer because it passes through the perforation 720 and the metal foam 730 in progress. This can be maximized. Therefore, the outside air passing through the carrier structure is purged by the carrier for purification, that is, all impurities and harmful substances are removed.

In some cases, it is also possible to form an inorganic film by anodizing only the metal foam, form a catalyst layer, and then roll in a spiral shape to form a cylindrical carrier structure.

Carrier for air purification produced in various ways can be used as the air purification device 110 of the present invention.

On the other hand, in addition to the above-described carrier for air purification, a carrier, which is another method, for example, a method of producing ceramic as a main material, may be applied to the air purification apparatus 110.

Although the present invention has been described by specific embodiments such as specific components and limited embodiments and drawings, it is provided to help a more general understanding of the present invention, and the present invention is not limited to the above embodiments, Those skilled in the art to which the present invention pertains can make various modifications and variations from this description.
