Next, a cooling apparatus and a cooling method according to the present invention will be described with reference to the accompanying drawings.

1 is a configuration diagram of a cooling apparatus according to the present invention, Figure 2 is a flow chart of the operation of the cooling apparatus according to the present invention.

1 and 2, the cooling device 100 includes a heat pipe 40 for cooling the indoor unit by a heat transfer method, a dehumidifier 20 for dehumidifying the indoor unit with a moisture absorbent 21a, and moisture. By using the latent heat of evaporation of the absorbed pulp paper 31, the indoor unit itself is able to function as a refrigerant because it is composed of a humidity compensator 30 for cooling the indoor unit and performing humidity correction.

At this time, the heat pipe 40 is the center, the dehumidifier 20 and the humidity corrector 30 is connected to the duct 50, the indoor unit is introduced into the inlet 11 of the housing 10 formed on the indoor side It is moved in the housing 10 by the blowing force of the inlet blower 11a and the exhaust blower 12a installed between the heat pipe 40 and the dehumidifier 20, and finally through the outlet 12 of the housing 10. Exhaust to the room.

The housing 10 is connected to both the indoor side and the outdoor side. An inlet 11 and an outlet 12 are formed and connected to the indoor side, and an exhaust port 13 is formed and connected to the outdoor side.

In addition, a cooling circulating jacket 41 is installed at the other side in the housing 10, and the coolant or cold air circulates through the inlet 41a and the outlet 41b to take away the sensible heat of the outer circumference and cool the heat pipe 40. to be.

Therefore, since the heat pipe 40 has a lower temperature on the other side than the one side, the indoor unit introduced from the inlet 11 and in contact with one side is deprived of sensible heat and cooled.

When the indoor unit is cooled through the heat pipe 40 as described above, the indoor unit moves to the dehumidifier 20 through the duct 50 installed at one side of the heat pipe 40.

The inlet blower 11a is installed in the duct 50 to suck the indoor unit through the inlet 11 of the housing 10, and the sucked indoor unit passes through the heat pipe 40 to the dehumidifier 20. Will move.

The dehumidifier 20 is connected to the heat pipe 40 and the duct 50 in front of the dehumidification rotor 21 rotated by the electric motor 22 and the heater 23 installed at the rear of the dehumidification rotor 21. ), And a blower 24 is installed at the rear of the heater 23 to blow toward the heater 23.

In the dehumidifier 20 configured as described above, the dehumidification rotor 21 chemically attaches a moisture absorbent 21a having a wide specific surface area such as silica gel, aluminum oxide, and zeolite to one surface of the ceramic plate 21b. It is shown in detail in Figure 3 to be wound in a concentric structure.

The dehumidification rotor 21 is rotated by the electric motor 22, while the indoor unit flows in the front while the water vapor contained in the indoor unit is absorbed by the moisture absorbent 21a, and is installed at the rear of the dehumidifying rotor 21 ( 23) is dried and exhausted due to hot air drying of the blower 24.

This process is repeated with the rotation of the dehumidification rotor 21, the inflow direction and the path of the indoor unit is the upper half and parallel to the inflow direction and the path of the hot air, respectively, if the indoor unit is introduced to one front side of the dehumidification rotor 21, Hot air flows into the other rear side.

That is, if water vapor is absorbed by the moisture absorbent 21a at the corresponding position at the front side of the dehumidifying rotor 21 and the indoor unit is dehumidified, the hot air introduced from the rear while the moisture absorbent 21a absorbed by the water vapor is rotated to the other side at the rear side. It is dried and regenerated by. This dehumidification and regeneration are repeated according to the rotation of the dehumidification rotor 21.

At this time, the water vapor evaporated by the hot air is exhausted through the exhaust port 13 of the housing 10 formed on the outdoor side.

In addition, the front of the heat pipe 40 and the dehumidifier 20 is connected to the two ducts 50, of which the inlet blower mentioned above in the duct 50 of the position closer to the one end of the heat pipe 40 11a is provided, and the exhaust blower 12a is provided in the duct 50 of a relatively distant position.

The inlet blower 11a and the outlet blower 12a are opposite to each other in a blowing direction, such that the inlet blower 11a sucks an indoor unit through the inlet 11 of the housing 10 and contacts the heat pipe 40. Then, if the air flows into the dehumidification rotor 21 to be dehumidified, the exhaust blower 12a blows the dehumidified indoor unit to be in contact with the heat pipe 40 again.

As the indoor unit dehumidified above is absorbed by the moisture absorbent 21a and the temperature is increased, the indoor unit is cooled by re-contacting the heat pipe 40 by the exhaust blower 12a.

In addition, the humidity corrector 30 is installed between the heat pipe 40 and the outlet 12 of the housing 10. The humidity corrector 30 is connected to the heat pipe 40 by the duct 50 so that the dehumidified indoor unit is introduced through the heat pipe 40.

The humidity corrector 30 is made of a porous pulp paper 31 attached to the rectangular frame 32 (shown in detail in FIG. 4). The pulp paper 31 is absorbed with moisture so that the indoor unit surface. While passing through the cooling by the latent heat of evaporation by moisture, the humidity of the indoor unit in a low humidity state by the dehumidification in the dehumidifier 20 is provided with a constant moisture at the same time is corrected.

As described above, the cooling device 100 according to the present invention operates while the indoor unit is circulated in the order of the heat pipe 40, the dehumidifier 20, the heat pipe 40, and the humidity corrector 30. Let's explain.

First, the indoor unit introduced through the inlet 11 comes into contact with the heat pipe 40 and cooled.

The cooled indoor unit is blown into the moisture absorbent 21a of the dehumidifier 20 to be dehumidified.

Since the indoor unit dehumidified through the dehumidifier 20 is accompanied by a temperature increase at the same time as the dehumidification, the indoor unit is fed back to the heat pipe 40 and recooled.

The cooled indoor unit is blown to the humidity corrector 30 and cooled by latent heat of evaporation, followed by humidity correction and finally exhausted into the room to control room temperature and humidity.

The moisture absorbent 21a in which moisture is absorbed during the dehumidification is dried in the heat of the heater 23, and the vaporized water vapor is exhausted to the outside through the exhaust port 13.

3 is a block diagram of a dehumidifier according to the present invention.

As shown in FIG. 3, the dehumidifier 20 includes a dehumidifying rotor 21, an electric motor 22, a heater 23, and the like connected to a belt for rotating the dehumidifying rotor 21.

The dehumidifying rotor 21 is formed by winding a rectangular long plate member 21b made of ceramic and a moisture absorbent 21a chemically bonded to one surface of the plate member 21b in a concentric manner.

Therefore, after winding, the dehumidification rotor 21 has a disc shape, and the electric motor 22 is connected to the belt on the outer circumference thereof to rotate in one direction according to the driving of the electric motor 22.

The dehumidification rotor 21 is a dehumidification area for dehumidifying the indoor unit introduced, and moisture absorbed by the absorbent 21a during dehumidification is heated by the rotation of the dehumidification rotor 21 by the hot air of the heater 23 and the blower 24. It is divided into a regeneration area which moves in the application direction and is dried and regenerated by hot air.

In the dehumidification area and the regeneration area, the inflow direction and the path of the indoor unit can be distinguished from each other because they are opposite and parallel to the inflow direction and the path of the hot air, respectively.

In addition, the regenerated absorbent 21a moves back to the dehumidification area according to the rotation of the dehumidification rotor 21 and can be dehumidified by contact with the indoor unit. Such regeneration and dehumidification are repeated by the rotation of the dehumidification rotor 21.

Since the regeneration region of the dehumidification rotor 21 is connected to the exhaust port 13 of the housing 10 and the duct 50, the regenerating area of the dehumidifying rotor 21 is absorbed by the moisture absorbent 21a by the blowing force of the blower 24 behind the heater 23. Then, the water vapor generated by hot air drying may be exhausted to the outside.

4 is a block diagram of a humidity corrector according to the present invention.

As shown in FIG. 4, the humidity corrector 30 has a structure in which a porous pulp paper 31 is fixed to a square frame 32 and an inner side of the frame 32. The front surface is located toward the heat pipe 40 and is connected to the duct 50 with respect to the heat pipe 40, so that the dehumidified and recooled indoor unit is introduced.

Since the pulp paper 31 absorbs moisture, the indoor unit passes through the pulp paper 31 and is cooled by latent heat of evaporation. In addition, the indoor unit is dehumidified in the dehumidifier 20, the humidity is corrected in a manner that is provided with lost moisture.

After the humidity correction in the humidity compensator 30, the indoor unit is exhausted into the room through the outlet 12 of the housing 10.

5 is a flowchart of a cooling method according to the present invention.

As shown in FIG. 5. The cooling method comprises a cooling method using a heat transfer method of the heat pipe 40, a dehumidification method using an absorbent 21a, and a cooling and wet compensation method using latent heat of evaporation of water. The regeneration process of the moisture absorbent 21a which consists of hot air drying with respect to (21a) is performed repeatedly.

The heat pipe 40 is water-cooled or air-cooled, the temperature of the other side is relatively lower than one side. The indoor unit in contact with one side is cooled by this heat transfer method.

During the cooling process, the indoor unit increases in humidity, and the indoor unit is hot and humid air originally contained in the room.

Once cooled, the indoor unit is blown and dehumidified by a dehumidifying method of the absorbent 21a. The moisture absorbent 21a is composed of a group of physical dry substances in which moisture to be contacted is absorbed, and more specifically, silica gel, aluminum oxide, zeolite, or the like. (S2000)

In addition, the moisture absorbent 21a in which the water vapor is absorbed is regenerated and reused without being discarded. The moisture absorbent 21a is used in a dehumidification process immediately after evaporating and evacuating water vapor by a hot air drying method. Therefore, in the dehumidification method using the absorbent 21a, the regeneration process of the absorbent 21a is repeated as well as the dehumidification process (S2100).

However, in the dehumidification process of the indoor unit, the humidity is removed, but the temperature of the indoor unit is increased. This is because the latent heat is changed to sensible heat when the water vapor is liquefied and transferred to the indoor unit. Accordingly, the indoor unit requires recooling.

Therefore, the indoor unit is subjected to a process of blowing and recooling the heat pipe 40. At this time, the humidity change is almost insignificant, and since the dehumidification process has been performed earlier, the humidity of the indoor unit is very low. (S3000)

However, in order to provide indoor units for human activity, correction of humidity as well as low temperature is required. Therefore, the indoor unit is used to compensate for humidity by using humidification for correction of humidity as well as cooling through latent heat of sensible heat during evaporation of water.

Humidity is corrected by the humidity correction process as described above, and the indoor unit cooled again after cooling of the heat pipe 40 is exhausted into the room.

In the cooling device and the cooling method according to the present invention as described above, the heat pipe 40 can be used in combination of a plurality of modules, of course, also in this case water cooling using the circulation jacket 41 mentioned in the present invention Or heat transfer is achieved by air cooling.

In addition, in addition to the structure using the porous pulp paper 31, the humidity corrector 30 may be used by replacing a plurality of long moisture pads in which moisture is absorbed in parallel along the height direction.

In addition, the inlet 11 and the outlet 12 of the housing 10, respectively, can be installed to use a separate filter, of course.

According to the cooling method and the cooling device according to the present invention as described above, since the use of a compressor or the like is eliminated compared to a general commercial air conditioner and cooling method, it is characterized by a low power high efficiency that can express a larger cooling rate with lower power There is this.

In addition, since it is closer to a natural cooling method, such as cooling and humidity correction of the indoor unit itself, rather than an artificial cooling method using a refrigerant, there is an advantage that can provide more comfortable cold air and humidity to human activities.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it is possible to make various modifications or variations without departing from the spirit and scope of the invention. Accordingly, the appended claims will cover such modifications and variations as fall within the spirit of the invention.
