It is possible to reduce the installation area and reduce the turbulent flow and flow resistance of the air supply in the air supply channel and prevent the flow unbalance of the cooling fluid to improve the heat exchange efficiency, It is possible to reduce the recirculation of the exhaust gas, thereby suppressing the heat exchange efficiency deterioration, to collect stable cooling water, and to perform the independent cooling operation for each supply channel according to the cooling load , One of the air supply channel configuration is broken or the other air supply channel configuration is cooled during maintenance, and even when some of the blowing fan units fail, the cooling operation is maintained by the remaining blowing fan units, And which can reduce the maintenance cost.

Generally, air conditioning equipment and refrigeration. Refrigerators or industrial heat exchangers operated in refrigerators or the like are accompanied by waste heat to be removed which is transferred from the hot fluid (or refrigerant) flowing in the cooling tower to the cooling air and discharged to the atmosphere.

The heat rejection type of the cooling tower is caused by evaporation of a part of hot fluid in a wet cooling open type heat exchanger in which hot fluid and cooling air are in direct contact with each other and heat exchange occurs Evaporative cooling to cool the hot fluid by latent heat of evaporation,

In a wet cooling closed circuit type heat exchanger in which hot fluid (or refrigerant) is indirectly in contact with cooling air and cooling water, air flowing through the outer surface of the closed heat transfer tube Indirect evaporative cooling for cooling (or condensing) a high temperature fluid (or a refrigerant) flowing through the inside of the heat transfer tube through the contact of the cooling water, heat transfer of the waste heat of the high temperature fluid flowing in the heat transfer tube through the tube wall at a high temperature Dry cooling to cool the hot fluid with sensible heat by transferring it to cooling air with lower temperature than the fluid, hybrid cooling type heat exchanger combining wet cooling heat exchanger and dry cooling heat exchanger And wet-dry hybrid cooling in which the high-temperature fluid is cooled.

And the cooling action can be divided into fluid cooling which lowers the temperature of the liquid (hot fluid, cooling oil, etc.) and fluid condensation which condenses by cooling the gas (refrigerant gas, steam, etc.) .

The cooling air and the cooling fluid flow are divided into a counter flow type in which the cooling air flows upward and a cooling fluid flows downward, an orthogonal flow type in which the cooling air flows horizontally and the cooling fluid flows downward, a cross flow type, and a parallel flow type in which cooling air flows in the same direction as a cooling fluid.

The ventilation system is a natural draft type that uses rising wind force due to difference in the inner and outer air density of natural wind or tower, a mechanical draft type that forced air through a blowing fan, , And an ejector draft type in which air is blown using a cooling fluid injection attractive force of an ejector.

In addition, the air blowing type is an induced draft type in which high temperature cooling air (hereinafter referred to as "exhaust") that has undergone heat exchange in the heat exchanging portion is sucked and discharged to the outside, And a forced draft type in which exhaust gas after heat exchange in the heat exchange section is discharged to the outside.

The discharge method of the exhaust includes a vertical exhaust type in which the fan is vertically upwardly exhausted through a fan cylinder vertical to the fan deck, a horizontal exhaust is horizontally exhausted through a fan cylinder configured horizontally in the side casing (Horizontal exhaust type).

In addition, the blowing fan type can be classified into an axial type fan generally used in a suction ventilation type and a centrifugal type fan used in a pressurized air blowing type.

In addition, the driving method of the blowing fan can be classified into a belt drive type, a gear reducer drive type, and a direct drive type.

 Next, a description will be given of a conventional induction blowing cooling tower to which the present invention is applied.

Cooling towers, The typical structure of the channel, the fan outlet, and the water collecting tank is shown in the reference photograph 1.

Reference 1. Composition of the cooling tower

References 1. Air supply channel and fan outlet of the pressurized air cooling tower

The pressurized air cooling tower has the advantages of reduced installation area (about 15 ~ 20% reduction) compared to the intake ventilated cooling tower, easiness of outdoor installation with obstacles (single intake and exhaust air supply structure), ease of indoor installation (in this case, Therefore, while there are advantages such as reduction of environmental induction,

(1) Due to the structure of the low-speed exhaust and the exhaust port compared to the suction blowing cooling tower, the recirculation of the high-temperature exhaust increases the heat exchange efficiency.

As shown in References 1 and 1, (2) In order to prevent the cooling water that falls out into the fan discharge port passing through the partition wall from being introduced, a downwardly inclined fan discharge port is extended close to the casing, and the partition and the long- And the air supply channel is narrowed.

③ The supply air supply structure is an air supply structure that flows into the heat exchange part while spreading in the direction of up and down, right and left, and fan outlet, after the discharge air supply is attached to the inner wall of the long side casing facing the fan discharge port. The consumption power of the pressurized cooling tower is increased by about 200 to 300%).

④ Due to the limit of collection capacity due to the structure of the water collecting tank at the lower part between the bulkhead and the casing, instability in the cooling water circulation (such as overflow due to fluctuations of air inflow and circulation cooling water in the cooling water circulation when the water level is insufficient) Waves occur in the water surface of the water tank.

(5) A single-suction cooling tower structure that constitutes a blowing fan section on one side of a casing on the longitudinal side, in which a plurality of cooling towers can be attached to a long-side casing and two or more cooling towers can not be continuously extended. (Cooling tower area + air supply space area) due to the provision of the air supply space at a predetermined interval in the outer direction of the air blowing fan unit in both cases where the two cooling towers are extended and mutually outward.

⑥ It causes side effect (operation frequency of water supply opening and closing due to wave, water loss and damage of the ball tap) to the operation of the water ball tap which is opened and closed according to the water level fluctuation due to the downward discharge air flow. And the like.

The following is a description of a prior art pressurized air cooling tower (hereinafter referred to as "prior art") having a pressurized air cooling tower structure as in the present invention, with reference to the accompanying drawings.

Fig. 10 is a schematic side cross-sectional view of a conventional pressurized air cooling tower, Fig. 11 is a schematic front view of a conventional pressurized air cooling tower, Fig. 12 is a schematic plan view showing a state of a blowing fan portion of a conventional pressurized air cooling tower, 10 is a schematic plan view showing a state in which a plurality of pressurized air cooling cooling towers are installed. As shown in the figure,

The long side casing 10a, the short side casing 10b and both side ends forming the heat exchange area 15, the water spraying area 16 and the air supply channel 14 are fixed to the inner surface of the short side casing 10a, A partition 11c partitioning the channel and the fan room 19b and forming a mounting opening 10c; A feed mechanism 19a provided in the long side casing 10a; An exhaust port 17 formed at the upper end of the casing 10a, 10b; A heat exchanging part (40a) disposed in the heat exchange area (15); A water spray main pipe arranged in a water spray area 16 formed in the upper part of the heat exchange part 40a and spraying the cooling water supplied to the heat exchange part 40a and having a cooling water inlet 51 on one side, A water spraying unit, a water spraying unit 50 composed of a plurality of water spraying nozzles coupled to the water spraying pipe; An eliminator 41 disposed on the water spraying unit 50 to collect water droplets scattered; A blowing fan portion 70c having a fan housing having an air supply outlet 74b fixed through the partition 11c; And a cooling water outlet 62 provided in one area of the water collecting tank 61. The cooling water outlet 62 is formed at a lower portion between the inner side surface of the long side casing 10a in the air supply direction and the inclined partition wall 11c And is provided with a collecting part 60 constituted by the collecting part.

The low-temperature, high-temperature exhaust after heat exchange is recirculated to the air supply mechanism 19a adjacent to the exhaust port 17 to reduce the heat exchange efficiency (recirculation) The heat capacity of the cooling tower may be reduced by about 25%),

As shown in Fig. 10, due to the limitation of the collection amount of the limited volume collecting portion 60 formed at the lower end portion between the inclined partition wall 11c and the long side casing 10a, instability in the cooling water circulation The flow of air into the cooling water circulation system, the overflow and shortage of the cooling water due to the increase / decrease of the circulation cooling water quantity, etc.)

(The frequency of the water supply opening and closing due to the wave is increased, the water loss is increased due to the fluctuation of the water supply opening due to the fluctuation of the water supply opening) due to the downward discharge airflow of the supply air outlet 74b, And damage to the bolt)

In either case where one cooling tower or the cooling fan part 70c side of the cooling tower is outwardly mutually outwardly and two cooling towers are installed and extended, as shown in Fig. 13, There is a problem that the total installation area (cooling tower area + air supply space area) due to the provision of the air supply space 19c can be increased.

Of course, the cross-sectional area of the cooling tower can be further improved to increase the volume of the supply channel 14 to further reduce turbulence and flow resistance of the supply air,

However, in this case, the installation area of the cooling tower is increased, which makes it difficult to reduce the installation area, which is the first advantage of the pressurized air cooling tower.

Since the problem of the above-described pressurized cooling air cooling tower is a typical problem in the pressurized air blowing type structure under the suggestion of reducing the installation area, since the pressurized air cooling tower has been developed, a plurality of blowing fan portions A narrow air supply channel 14 formed between the inclined partition wall 11c and the long side casing 10a and a narrow air supply channel 14 formed at the lower end between the partition wall 11c and the long side casing 10a, The structure and structure of arranging the discharge port 60 and the supply / discharge port 74b downward in the lateral direction of the inside of the long side casing 10a are almost maintained as they are.
