Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooling tower in a refrigeration system or the like, which sprays cooling water for releasing exhaust heat to lower the temperature.

[0002]

2. Description of the Related Art In refrigeration cycles and absorption cycles of refrigeration systems and air conditioners, etc., in order to lower the temperature in a refrigerator or room, waste heat collected from the refrigerator or room is radiated to the outside via a condenser or the like. I do. In order to increase the heat radiation efficiency at the time of heat radiation, a cooling tower is used in which a cooling water is sprayed in a heat radiating section to forcibly send wind and utilize the heat of vaporization to lower the temperature of the cooling water. In these cooling towers,
Cooling water, whose heat has been recovered by a condenser or the like, is sprayed on several cooling radiators by a sprinkler, and the temperature of the cooling water drops by self-cooling due to heat of vaporization while flowing down the surface of the cooling radiator. The cooling water that has become low temperature in the cooling tower is again supplied to a condenser or the like, and circulated between the cooling tower and the condenser.

As described above, in the cooling tower, while the temperature of the cooling water is lowered while flowing down the surface of the cooling radiator plate, it is desirable to increase the surface area of the cooling radiator plate so as to increase the surface area of the cooling water. In addition, a large number of cooling radiators made of vinyl chloride sheet or the like are layered with a space interposed therebetween to secure a contact area between the cooling water and air sprayed on each cooling radiator plate.

[0004]

However, in a refrigerating apparatus or the like using a cooling tower, when the size of the apparatus is reduced, the size of the cooling tower is limited. Can't be bigger. For this reason, it is necessary to increase the efficiency of heat radiation within the limited dimensions, and for that purpose, the cooling water is spread all over the surface of each cooling radiator plate to surely lower the temperature of the cooling water. There is a need.

However, in order to reduce the size of the cooling tower, if the space between a large number of cooling radiators made of vinyl chloride sheets is narrowed to reduce the interval between the cooling radiating plates, a cooling radiator having a small rigidity is used. In such a case, the influence on the cooling water flow due to the difference in the space between the layers increases due to the variation in the shape. For example, when the space between the layers becomes about 1 cm or less, the cooling water stays due to surface tension and flows down smoothly. On the other hand, if it is larger than 1 cm, excessive cooling water will flow down at once and water droplets will be scattered. In either case, there is a problem that the cooling performance is reduced.

According to the present invention, in a cooling tower for cooling by dispersing cooling water on each cooling radiator plate by providing a space between a plurality of cooling radiator plates and spraying cooling water on each cooling radiator plate, the cooling capacity of the cooling tower can be reduced. It aims at miniaturization.

[0007]

According to claim 1 of the present invention,
A plurality of cooling radiators are arranged in the vertical direction, an air passage space is formed between each cooling radiator, and the plurality of cooling radiators are horizontally layered. In a cooling tower that cools cooling water by dispersing cooling water flowing down from a water sprinkler disposed above to the plurality of cooling heat radiating plates, the water sprinkler includes an upper end of each of the plurality of cooling heat radiating plates. Is formed as a plurality of guide grooves for adjusting the interval between the layers by inserting the respective grooves.

According to the first aspect of the present invention, when a plurality of cooling radiators are arranged below the water sprinkler, the upper end of each cooling heat radiator is inserted into the guide groove of the water sprinkler. The spacing between the upper ends of the cooling radiator plate is adjusted,
The upper end of each cooling radiator plate can be maintained at a predetermined interval between layers.

As a result, the amount of cooling water supplied becomes small because the interval between the layers is narrow, or the amount of cooling water supplied becomes excessive because the interval between the layers is large, and the water flows between the cooling radiating plates at a stretch. The cooling water flowing down from the sprinkler is distributed evenly to each cooling radiator plate at regular intervals to prevent the water droplets from being scattered, so that the surface of each cooling radiator plate is evenly distributed. Flow down while getting wet. As a result, the cooling performance of the cooling water in each cooling radiator plate becomes uniform, and the cooling performance does not decrease.

According to a second aspect of the present invention, in the first aspect, an edge of the plurality of guide grooves is chamfered to facilitate insertion of each end of the plurality of cooling radiating plates. And With this configuration, it is easy to insert the ends of the plurality of cooling radiating plates into the guide grooves, and it is possible to smoothly perform the assembling work of the cooling tower and shorten the assembling time, thereby improving the productivity.

According to a third aspect of the present invention, in the first and second aspects, the water sprinkler comprises a water sprinkling pipe formed by dispersing a plurality of water spouts in a direction in which the plurality of cooling radiating plates are stacked. A disperser that is disposed along the sprinkling pipe below and that includes a roof-like member that disperses the cooling water flowing down from the sprinkling pipe, wherein the plurality of guide grooves are formed below the disperser. The provision of the plate member with a guide groove is technical means.

As described above, according to the third aspect, since the guide groove for inserting the cooling radiator plate is located below the roof-like member which is the distributor, the cooling water flowing down from the sprinkling port of the sprinkling pipe is:
Since the cooling water is dispersed on the surface of the roof-like member and is not directly transmitted to the plate member with the guide groove, there is no influence on the watering path.
Further, the disperser and the plate member with guide grooves can be integrally formed, and the number of parts does not increase, so that the cost can be reduced.

According to a fourth aspect of the present invention, in the third aspect, the roof-like member of the disperser has a technical shape of having a substantially arc-shaped cross-sectional shape. As a result, since the upper end of the disperser is not simply angular and rounded, the cooling water flowing down from the sprinkling pipe to the roof-shaped member does not immediately flow to both sides of the roof-shaped member, and the roof is not spilled. The cooling water can be dispersed over a wider range because it also spreads in the arrangement direction of the shaped members.

According to a fifth aspect of the present invention, in the third aspect, an interval between the plurality of water spouts of the water sprinkling pipe and an overlapping interval between the cooling radiating plates are the same, and the arrangement position of each of the cooling radiating plates is set to the same value. The technical means is to correspond to the position of each water spout. Thereby, the cooling water that has flowed down from the sprinkling port of the watering pipe correctly flows down to each cooling radiator plate, and the amount of cooling water flowing down to each cooling radiator plate can be made uniform. As a result, the cooling capacity of the cooling water in each cooling radiator plate is not reduced.

According to a sixth aspect, in the first to fifth aspects,
A regenerator for heating the absorbing liquid containing the refrigerant to separate the refrigerant vapor from the absorbing liquid, a condenser for cooling and condensing the refrigerant vapor separated by the regenerator, and a low-pressure refrigerant for condensing the refrigerant in the condenser. An absorption cycle comprising: an evaporator for evaporating under the evaporator; an absorber for absorbing the refrigerant vapor evaporated by the evaporator into an absorbent supplied from the regenerator; and a pump for returning the absorbent from the absorber to the regenerator. In the absorption refrigeration apparatus formed with the above, technical means is that the cooling tower is provided in a circulation circuit of cooling water for cooling the condenser.
