The present invention relates to a cross-flow cooling tower for cooling cooling water or condensing a refrigerant, and more particularly, to a cross-flow cooling tower having a protruding sprinkling chamber.

Generally air conditioning and refrigeration. Refrigerators or industrial heat exchangers operating in refrigeration equipment, etc., are accompanied by waste heat to be removed. To remove this waste heat, the waste heat must be released to the atmosphere using a cooling medium. The cooling method of cooling tower is divided into air-cooled cooling that performs convective cooling by forced convection of atmospheric air that is lower than the fluid to be cooled, and evaporative cooling that uses cooling latent heat by contact of cooling water and air. Cooling towers are widely used because they provide greater cooling and economical efficiency than any other cooling system.

Conventional cooling towers have a counter flow type cooling tower in which air flows vertically and coolant flows vertically, and a cross flow type in which air flows almost horizontally and the cooling water flows vertically. Cooling water flow is divided into cooling tower, open water for evaporative heat exchange while flowing coolant and air-filled material, and cooling water and cooling fluid on the outer surface of a closed cooling coil in which cooling fluid (cooling water or refrigerant) flows into the pipe. It is divided into hermetic evaporative heat exchange while contacting air.

7 is a schematic longitudinal cross-sectional view of a conventional cross-flow cooling tower. As shown,

Conventional cross-flow cooling tower 100 is composed of a pair of louvers 165 for recovering the air inlet guide and the water droplets to the cooling tower into the cooling tower, the casing 151 formed on the louver 165 and both sides. A heat exchange region is formed by a casing (not shown).

And the sprinkling part 130 is provided through the bottom of the tubular sprinkling tank 136 and the sprinkling tank 136, the top of which is opened and consists of a plurality of spraying nozzles 133 to spray cooling water using gravity of the head. The upper part of the louver side casing 151 and the lower part of the fan deck 112 are arranged to face each other.

In addition, the side plate surface of the watering tank 136 is mounted to the windshield 113 to prevent the air flows to the fan portion 120 through the watering area 137 to form the watering area 137.

And a cooling water inlet 141 and a cooling water inlet pipe 140 for introducing high temperature cooling water, a first distribution pipe 131 branching from the cooling water inlet pipe 140 to guide the cooling water to the water spray tank 136, and A discharge diffuser 139 is provided between the lower portion of the first distribution pipe 131 and the upper portion of the sprinkling tank 136 and discharges the cooling water evenly into the sprinkling tank 136.

In addition, the fan tech 112 formed at the bottom of the fan unit 120 is coupled using a coupling jaw (not shown) formed at an upper end of a pair of watering tanks 136 facing each other as a coupling unit.

A heat exchanger 160 formed of a filler is disposed under the watering area 137 formed at the bottom of the pair of watering tanks 136.

In addition, a louver 165 is provided at the outside of the pair of heat exchangers 160 to guide the air inflow and recover the coolant that is released to the outside, and the water droplets scattered toward the fan 120 through the heat exchanger 160 are provided inside. The eliminator 166 to collect | recover is provided.

In addition, a collection tank 170 is disposed below the heat exchanger 160 to collect the coolant that is heat-exchanged through the heat exchanger 160, and integrally formed in one region to form the discharge sump 171 and the cooling water outlet 172. A support mount 190 for supporting the cooling tower is provided below the collection tank 170.

By such a configuration, the high temperature coolant introduced into the coolant inlet 141 is introduced into the sprinkling tank 136 through the coolant inlet pipe 140, the first distribution pipe 131, and the discharge diffuser 139 to have a predetermined depth. Will be stored.

The high temperature cooling water stored in the water spray tank 136 is sprinkled on the heat exchanger 160 through the plurality of water spray nozzles 133, and the hot water of the cooling water flows vertically downward in the heat exchanger 160. The heat exchanged and cooled coolant by water

It is collected at 170.

On the other hand, the air introduced through the louver 165 flows through the heat exchange part 160 in a substantially horizontal direction, and then exhausts heat through the fan part 120 after passing through the eliminator 166.

The coolant collected in the sump 170 is supplied to a cooling load facility (not shown) through the discharge sump 171 and the cooling water outlet 172 and absorbs heat through the cooling load facility (not shown). Is re-introduced into the coolant inlet 141 for cooling, and this circulation process is repeated.

The conventional cross-flow cooling tower 100 has the advantages of low drop noise compared to the counter-flow cooling tower and easy inspection and repair inside the cooling tower, while the cooling water overflows through the sprinkling tank 136 having an upper opening. The high frequency of induction causes loss of cooling water, and the water sprinkling tank 136 exposed to the atmosphere inhabits microorganisms by photocatalytic action and external foreign substances flow into the cooling water system, which promotes sprinkling failure and water pollution. There is a problem of lowering efficiency and increasing maintenance costs.

In addition, the windshield plate 113 is formed on the side plate surface of the water spray tank 136 to form the water spray region 135, and thus, airtightness and weakness of the air may be bypassed without passing through the heat exchanger 160.

In addition, due to the structural characteristics of the conventional cross-flow cooling tower 100, the upper region of the heat exchanger 160 where a stronger suction force is applied adjacent to the air outlet 129 of the fan unit 120 increases than the average design air flow of the entire area of the air flow. Air is flowed, and some of the high temperature exhaust discharged to the outside through the ventilation fan is recycled, and the cooling tower performance may be severely degraded, especially when the exhaust recycle is severe due to the low pressure or the deflection.

As the vertical distance of the heat exchanger 160 from the intake port 129 increases, the air flow rate decreases toward the lower region of the heat exchanger 160 as the suction force decreases, so that the air flow does not lean or flows in the lower region. A heat exchange dead area may be generated, and an imbalance occurs in the heat exchange contact due to an airflow deviation between the upper region and the lower region of the heat exchanger 160, thereby lowering the heat exchange efficiency.

In addition, due to the weight of the sprinkling tank 136 to store the cooling water to a predetermined depth increases the required support cost and basic construction cost, the surface of the sprinkling tank 136 during the inspection or maintenance work at the top of the cooling tower 100 Inconvenient and unsafe by using as a work furnace, the upper exposure area 200 is increased due to the fan portion 120 and the coolant inlet pipe 140 and the first distribution pipe 131 is formed on the top of the sprinkler tank 136 to aesthetics There is a problem of damage.
