[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION This invention relates to a counter-flow cooling tower.

[0002]

2. Description of the Related Art A counterflow type cooling tower of this kind and a load section (for example, a refrigerator) are connected via a separately installed circulation pump via a long pipe.

[0003]

When the conventional countercurrent cooling tower described above is installed on the top floor of a small-scale building or in a confined place, a place for installing the cooling tower and a place for installing the circulation pump are secured. The required cooling capacity cannot be achieved, or a separate installation location for the circulation pump must be secured.

The object of the present invention is to provide a space-saving and space-saving type in which the drawbacks of the above-mentioned prior art are improved at once by improving a base for sharing and supporting the load of the countercurrent cooling tower together with the legs. That is, it is an object of the present invention to provide a countercurrent cooling tower with a small amount of protrusion of the circulation pump from below the lower water tank accompanying the integration of the lower water tank and the circulation pump.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is directed to a leg for supporting a lower water tank in a countercurrent cooling tower having a blower at an exhaust port and having an outside air intake all around. All of the bodies are interconnected by a horizontal stay near the lower end of each leg, forming a frame of the cooling tower, and forming a main frame in a square or a triangle when viewed from above with the stay, and The circulation pump and its entire driving motor are substantially housed between the water tanks, and a suction port of the circulation pump is connected to a circulation cooling water outlet provided on a side surface of the falling water tank in the lower water tank. Is mounted and fixed on a flat rectangular support frame that is a part of the main body frame, the circulating cooling water inlet is provided on the front surface of the falling water tank, and the circulating cooling water outlet is provided on a side surface perpendicular to the front surface. And this circulation The counter flow cooling tower characterized in that the axis of the suction pipe, which is the short pipe of the circulation pump, extends at right angles to the water outlet, and the suction port of the suction pipe is directly connected to the outlet by an elastic joint. is there.

[0006]

The operation of the present invention will be described below. The counter-current cooling tower is operated to spray hot water from a load unit such as a refrigerator through the circulating cooling water inlet provided in the dropping water tank to the sprinkler of the counter-current cooling tower onto the filler. The hot water is cooled by the latent heat generated by the evaporation of the hot water. Thereafter, the cooling water is collected in the dropping water tank, and by operating the circulating pump, the cooling water is immediately sucked from the suction port of the circulating pump connected to the circulating cooling water outlet of the dropping water tank, and is sent from the discharge port of the circulating pump. It is sent to the load section through a water pipe and used for circulation. During this operation, the weight of the countercurrent cooling tower and the load of the circulating cooling water are shared and supported by all of the legs and the body frame that is the gantry. Further, the load of the circulation pump is supported by the support frame. At this time, since the entire circulation pump and its driving motor are substantially housed under the lower water tank, the portion protruding outward from the lower water tank of the cooling tower is extremely small, and the cooling tower installation space with a little room is provided. If present, this circulation pump and its driving motor together with the countercurrent cooling tower are installed in the same place.

[0007]

Next, a typical embodiment of the present invention will be described. In FIG. 1, A is sent from a load unit (not shown) such as a refrigerator to a watering pump 42 of a watering device 13 through a circulating cooling water inlet 12 and a rising pipe 30 provided in a falling water tank 11 of a lower water tank 10. The incoming warm water is sprinkled on the filler 14 in the main body 43 and the motor 5
By rotating the blower 44 provided at the exhaust port by the drive of 2, the air is taken in from the louver 45 over the entire circumference, which is the outside air inlet, and brought into contact with the airflow in a countercurrent manner, and the hot water is cooled by the latent heat by the evaporation, Thereafter, the cooling water is collected in the dropping water tank 11 and, by the operation of the circulation pump C, is sucked from the suction port 16 of the circulation pump C connected to the circulation cooling water outlet 15 of the dropping water tank 11, and the circulation is performed. This is a counter-current cooling tower of a type that is sent from the discharge port 17 of the pump C through a water pipe (not shown) to the load section and circulated for use. At least three legs 18 supporting the lower water tank 10 in the counter-flow cooling tower A are interconnected by a horizontal stay 19 near the lower end, and constitute a gantry B of the cooling tower. To form the body frame 20 in a triangle,
Between the main body frame 20 and the lower water tank 10, the circulation pump C and the entire drive motor D are substantially housed, and
A suction port 16 of the circulating pump C is directly connected to a circulating cooling water outlet 15 of the dropping water tank 11 by an elastic joint 21, and the circulating pump C is a flat rectangular support frame which is a part of the main body frame 20. 22 and is fixed. The drive motor D is covered if necessary [not shown]

[0009]

According to the first aspect of the present invention, at least three legs supporting the lower water tank in the countercurrent cooling tower are interconnected by a horizontal stay near the lower end,
The cooling tower is configured as a mount, and the stay is formed in a rectangular or triangular body frame when viewed in a plane.The circulation pump and the entire drive motor are substantially housed between the body frame and the lower water tank, and The suction port of the circulating pump is connected to the circulating cooling water outlet of the dropping water tank in the lower water tank, and since the circulating pump is mounted and fixed to a part of the main body frame, it is collected in the dropping water tank. The cooled circulating cooling water that has been cooled can be immediately sucked by the circulating pump without passing through a long pipe, and the piping work and maintenance management can be omitted. During this operation, the self-weight of the countercurrent cooling tower and the load of the circulating cooling water, by all the legs and the gantry,
The support can be shared, and the rigidity of the legs can be made lower than conventional ones.

Further, the load of the circulating pump can be supported by the support frame, and the whole of the circulating pump is substantially housed under the lower water tank, so that a portion protruding outside the lower water tank of the cooling tower can be made very small. If there is some space for installing the cooling tower, this circulation pump and its drive motor can be installed together with the countercurrent cooling tower in the same place, and this circulation pump and its drive can be installed on the peripheral wall of the countercurrent cooling tower installation place. A situation where the motor cannot be installed due to contact with the motor can be avoided. Further, in the case where a blower is provided at the exhaust port as disclosed in Japanese Utility Model Application Laid-Open No. 53-43262, the installation direction of the cooling tower is limited so that the air supply port is not closed by the peripheral wall of the installation location. In the present invention, since there is an outside air intake all around, the cooling tower can be installed without such restrictions. That is, the installation space and installation space of the counter-current cooling tower can be reduced without being limited to the direction, and the counter-current cooling tower of the present invention can be easily installed even on the top floor or in a narrow place of a small building. .
