Description

[Detailed explanation of the invention] In this invention, cooling pipes with a planar spiral shape are arranged in multiple stages within the casing, and the heat exchange area of the cooling pipes is larger than that of straight pipes. The cooling tower, which is much larger and has significantly better cooling capacity, is characterized by having a water tank 12 at the bottom, an air intake 2 at the bottom, and a fan 3 at the top. A vertical central header 6 to which a water supply pipe 6' is connected at the bottom is provided in the center of the casing 1 having the opening 4;
Cooling pipe 8 having a spiral planar shape with an inner end opening inward
The outer end of each drainage header 7a is opened into a plurality of drainage headers 7a to 7f provided inside the casing 1.
A vertical water sprinkling header 5 is connected to the annular collecting pipe 10 having an outflow pipe 10a on one side at the upper end of ~7f, and the water in the lower water tank 12 is supplied to the central header 6 by a pump 13. A sprinkler 11 is attached to the upper end of the water sprinkling header 5 through which the water supplied from the water sprinkling header is spouted diagonally downward and rotated horizontally by the reaction.

In the above configuration, the central header 6 is a cold water supply header,
The surrounding vertical headers 7a to 7f are used as drainage headers, and a water supply pipe 6' is connected to the lower side of the central header 6.

In addition, in the illustration, six cooling pipes 8a to 8f are arranged in a spiral shape running in parallel on the same plane, and the outer ends of each cooling pipe are successively connected to outflow headers 7a to 7f. A plurality of parallel cooling tube groups are arranged in multiple stages above and below.

In addition, each cooling pipe is inclined so that the outer end is higher than the inner end on the center side, so as to facilitate air removal and water removal during a water cutoff.

The cooling tower of the present invention has the structure described above, and the cooling tower (
The cooling water flowing into the central header 6 from the central header 6 flows through each cooling pipe 8a, 8b...8f, enters each vertical header 7a...7f, and flows into the upper collecting pipe. It is returned to the cooler through the outlet pipe 10a of 10.

Therefore, the cooling water flowing in the cooling pipes 8a, 8b...8f is
It is cooled by the latent heat of vaporization of the water sprinkled from the sprinkler 11, but in the present invention, since the cooling pipes 8a, 8b, . . . 8f are spirally shaped, the cooling pipes 8a, 8b...8f have a much longer flow path and a larger surface area than straight pipes, so their heat exchange capacity is significantly improved compared to straight pipes. There is.

Furthermore, by forming the cooling pipe in a spiral shape, the space within the casing can be used effectively and economically, and a cooling tower with little dead space and therefore compactly assembled can be provided.

In addition, the sprinkler 11 is caused to rotate by itself due to the reaction of the water jetted diagonally downward, so to drive the sprinkler, water is pumped up from the lower water tank and the sprinkler is driven.
The water supply pump 13 is sufficient, and there is no need for a motor for driving the sprinkler, which has the advantage of reducing manufacturing costs and running costs.
