Description

{Air Cooler using Copper Foil}

Technology that uses the heat exchanger using copper thin film in the principle of cooling air using the heat of vaporization of water, effectively extracting only cold air without raising the indoor humidity, so that the room air is cool and comfortable

Conventional refrigerators circulate water to evaporate water to obtain cold air. At this time, vaporized water vapor also spreads into the room together with the air, thereby increasing the humidity. When the indoor humidity is increased, evaporation of sweat is suppressed, so the coolness is not felt and the discomfort index is increased. Accordingly, the present invention efficiently extracts only the cold air obtained from the vaporizing action of water without releasing moisture into the room, and cools the indoor air pleasantly, so that the air conditioner can be replaced only with less electricity.

1. How can you efficiently extract only the cold air from the vaporization of water to cool the air without releasing moisture into the room?

2. What material is the most efficient way to make heat exchangers?

A key means of solving the problem is to make a heat exchanger using a copper thin film with a thickness of 0.01 mm to 0.02 mm. The copper thin film is highly suitable for the heat exchanger of the present invention because it has high thermal conductivity, good durability and weatherability, and can maximize the surface area with a small weight. The copper thin film requires a large amount, so if there is no problem with durability, the thinner the heat exchange performance, the lower the cost, the lighter the product weight. Taking the basic size of the device as an example, the copper thin film required to fill the inside of 0.7M x 0.5M x 0.9M weighs only about 3Kg, but it is 0.4M wide and has a length of about 40M and a surface area of 32 square meters. Water is evaporated from the surface of half of the 16 square meters, and heat exchange occurs in the other half, so that room air can be cooled very efficiently. The copper thin films are alternately arranged in the longitudinal direction at intervals of about 6 mm to 10 mm and are alternately arranged in a vaporizing space where water evaporates in each space divided by the thin film and a cooling space where heat exchange is performed between indoor air, So that the air can be cooled. At this time, the air evaporated from the water must be taken out of the room separately. However, since the apparatus becomes simple by disposing the air conditioner itself outdoors, it is preferable to use an outdoor installation type as the basic structure.

The heat of vaporization of water is 100 ° C and 539cal / g, which is the amount of heat required to raise 539g of water 1 ° C at room temperature. The heat of vaporization of water is larger than that of any other substance, and therefore, sufficient cooling effect can be obtained even with a small amount of energy. Indeed, the energy circulation and temperature changes on Earth are phenomena caused by water evaporation and rainfall, and it is the same principle that the body controls the body temperature through sweat. Therefore, if the evaporation phenomenon of water, which is often available and environmentally friendly, is well utilized, cooling effect can be obtained to replace air conditioner as much as possible. The present invention can efficiently cool the air without increasing the humidity through the heat exchanger using the copper thin film having high thermal conductivity and large surface area since the conventional refrigerator can not properly separate the cold air and the moisture. , Unlike air conditioners, which consume a lot of energy from the condenser, only 20% of the air conditioners can be replaced with air conditioners only by the fan and submersible motors. But the ripple effects will be great globally.

FIG. 1 is a front view of the present invention. As shown in FIG. 1, when the cooling fan 6 is turned, an air flow 7 for vaporizing water is generated from left to right. The air and the copper foil 11 are cooled by the heat of vaporization, And the cooling air 4 passing between them is moved from the upper side to the lower side, cooled by heat exchange, and then supplied to the room. The present invention can be installed indoors, but it is mainly installed on an outdoor wall or a roof, and sucks room air or outside air into the cooling air inlet 1 to lower the temperature, and then supplies the indoor air through the cooling air outlet 2.

 FIG. 2 is a left side view of the present invention showing a structure in which copper thin films 11 are closely arranged longitudinally, and a structure in which water tied to a water tank is supplied to the upper copper thin film supporting pipe 14 Water 18 that flows down through the thin cloth 13 or mesh or hydrophilic coating adhered to the copper foil 11 and flows down through the lower copper thin film supporting pipe 20 The water is collected in the water pipe 5 and flows into the water tank in which the water motor 9 is located. The water tank is provided with a water level control valve (19), and water is supplied from the water connection hose (16) by the amount of water to be evaporated.

 The copper thin film, which is a core part of the present invention, is formed by arranging the support tube frame 23 of FIG. 3 on the right and left sides and the upper and lower ends and drilling holes in the frame to connect the upper copper thin film supporting tube 14 and the lower copper thin film supporting tube 20 After fixing the copper foil, the copper foil is stretched and attached to the support pipe at the upper and lower ends like a cloth repeatedly and repeatedly arranged as shown in the figure. As shown in FIG. 6, the copper thin film support tube structure 46 is formed by laminating two rows of holes in a thin aluminum, plastic, or stainless steel pipe at an angle of about 90 to 150 degrees from the central axis, The upper copper thin film support tube 14 is directed downward and the lower copper thin film support tube 20 is disposed facing upward so that water can be evenly supplied to the surface of the copper film and recovered. The lower copper thin film supporting pipe 20 can be replaced with the same shape as the hole array placing tube 48 of FIG.

 When the apparatus is operated, the underwater motor 9 circulates, water is uniformly supplied to the surface of the copper foil 11, and the cooling fan 6 is circulated to generate a flow of vaporized air 7 that vaporizes water, (11) is cooled, the cooling air (4) passing through the side compartment is cooled by the heat exchange phenomenon. FIG. 3 is a partial perspective view of the present invention and shows the operation principle and structure in detail. Here, the diaphragm 22 separates the two different air flows so that they are not mixed, and is made of metal or plastic.

When this unit is operated, the air temperature can be obtained about 6 ~ 8 degrees lower than the surrounding air as it has been proven in the existing air conditioner, and usually it is possible to obtain a considerable cooling effect only by this degree, .

In the cooling performance of the present invention, if the heat is severe, an additional temperature lowering may be required. In this case, the double cooling fan system shown in FIG. 4 can be solved. The basic principle of the dual structure cooling device is that the cooling auxiliary body 34 is attached to the structure of the basic cooling body 33 so that the vaporized air 25 for vaporizing water is cooled and supplied beforehand to further lower the temperature. The structure of the inside of the cooling auxiliary body 34 is substantially similar to that of the inside of the cooling body 33. Fig. 5 shows the structure of the cooling auxiliary body 34 in Fig. 4, It shows its structure and working principle in perspective view. Here, the water supply pipe 28 can be used jointly on the cooling body 33 side and the cooling auxiliary body 34 side. Unusual is that the water is supplied to the upper copper thin film support pipe 39 from the cooling auxiliary body 34 side Water is supplied through the water supply tubing 38 disposed thereon, and flows down the upper copper thin film supporting pipe 39. Therefore, the upper copper thin film support tube 39 and the lower copper thin film support tube do not need holes for water supply and recovery, but instead have a diameter of about 5 to 90 degrees from the center axis, as seen in the water supply tubular structure 47 of FIG. And the water is directed downward on both outer sides of the copper foil 40. The water thus flowed falls to the cooling auxiliary body 45 and then flows into the water tank 31 in which the water supply tubing 38 can be replaced with the same shape as the row hole arrangement tube 48 of FIG. At this time, the cooling assisting body air 26 in the cooling assisting body 34 enters the apparatus through the air suction port 35 by the operation of the cooling assisting body ventilator 32, The air direction may be reversed. When the dual structure cooling device is operated, as shown in FIG. 4, the pre-cooled vaporized air 24 passing through the cooling auxiliary body 34 passes again through the cooling body 33 and evaporates water to further lower the temperature, The cooling air 27 is cooled to a lower temperature.

The present invention can replace the function of the air conditioner only by using the energy of about 20% of the air conditioner by using only the heat of vaporization of water, and can be easily installed in all houses, office buildings, schools, public institutions, factories, Can be supplied at a much lower cost than air conditioners. It can supply about 9 cubic meters of air per minute at 0.7M (horizontal) x 0.5M (vertical) x 0.9M (height) To 6 to 8 degrees lower than the outside temperature. Because it does not weigh much compared to the product size, it can be applied to any size by increasing the size or increasing the size on the wall or roof of a large building such as a school classroom, an office, a factory, etc., and it can be installed as a central cooling system. In addition, it is not necessary to install an indoor unit and an outdoor unit such as an air conditioner, and only a single unit can be installed, thus saving cost and space. When the present invention begins to spread, it will spread rapidly to domestic and foreign countries, and contribute to domestic industrial development, promotion of employment, and also to mitigate global warming.
