Description

[Detailed description of the invention] This invention relates to a cooling tower, and is designed to allow pipes through which water to be cooled to pass to be easily and firmly fixed, and to easily increase or decrease the number of pipes depending on the size of the heat exchange capacity. This relates to a cooling tower that is suitable for mass production.

Conventionally, heat exchangers as cooling towers used in coolers, etc.
As a heat exchanger according to Publication No. 257) or as a heat exchanger according to
It has been proposed as a heat exchanger according to No. 5-5444 (Japanese Patent Publication No. 36-21647), but the Utility Model Application No. 51778
In the heat exchanger according to No. 4, a supporting material is provided around a vertically rising central header, a flexible spiral tube supported by this supporting material is arranged so as to surround the central header, and the supporting material is A flexible spiral tube is formed with one end opening into an outer header disposed vertically around the central header and the other end opening into the central header.

Therefore, the structure becomes very complex, and there is no compatibility of heat exchanger parts between small coolers that require a small heat exchange capacity and large coolers that require a large heat exchange capacity. The drawback was that the heat exchanger had to be redesigned each time depending on the size of the cooler.

On the other hand, in the heat exchanger according to Japanese Patent Application No. 35-5444, a large number of semicircular notches are carved on the sides of a rectangular heat conduction plate, and tubes are inserted into the semicircular notches from the side. The tube is spirally curved, and the 20 sides of a rectangular heat conduction plate with many semicircular notches cut into the sides are applied from the outside of the spirally wound tube to form a semicircle and a semicircle. A structure in which a spirally wound tube is inserted into each hole formed by a circle, or a rectangular heat conduction plate with a number of horizontally elongated holes vertically drilled, and the center of each company placed approximately in the center of these holes. This heat exchanger has a structure in which a rectangular heat-conducting plate is curved along a line passing through it, and a spirally formed tube is sandwiched between the semicircular notches formed by the curve.

Therefore, the rectangular heat conduction plate must be processed in advance according to the number of turns of the tube, and when the number of turns of the tube is increased or decreased to match the size of various coolers, the size of the rectangular heat conduction plate must be changed each time. Because it is essential, there is no interchangeability of parts and it is not suitable for mass production.

That is, both of the above-mentioned heat exchangers on the two sides are not suitable for mass production, and therefore have the drawback that cost reduction through mass production cannot be achieved and they become extremely expensive.

Therefore, this invention was devised in view of the above-mentioned drawbacks, etc., and its gist is that the fins are formed by sequentially fitting a large number of disk-shaped pieces around the outer periphery, or by winding strips in a spiral manner. The formed pipes are wound into a sparse spiral shape with a space in the center, and a plurality of these pipes are arranged with gaps above and below, and on the other hand, the spiral pipes are arranged in a substantially radial direction. forming a plate having fitting portions on the upper and lower edges thereof, into which the pipes are fitted and locked for each turn of the spiral, and a plurality of plates are provided in the gaps between each of the plurality of pipes. The pipes and plates are alternately stacked by distributing them approximately evenly around the entire circumference and standing in the radial direction, so that both ends of each pipe are connected to the header and the cooled water outlet. A ventilation section with a built-in rotating fan is provided above the center of the stacked pipes, and a water tank section for sprinkling water is provided above the spiral shape of the stacked pipes.
A water receiver is provided below to receive the water.
The pipe and plate are formed to be held by a rising part which is the peripheral wall of the water receiving part and a hanging part of the water tank part, and these are shifted in position from the perfect circle by one turn of the spiral pipe. This is due to the shape.

Hereinafter, embodiments of this invention will be described with reference to the drawings.

In the figure, 1 is a pipe made of metal such as copper, which is wound into a sparse spiral shape with a space 2 in the center.

The pipe 1 is formed by sequentially fitting a large number of disc-shaped parts made of aluminum or its alloy into the pipe 1, or by attaching strip-shaped fins 3 by winding strips of aluminum or its alloy in a spiral shape. It is something to do.

In addition, at this time, the fins 3 may be attached to the straight pipe 1 first, and the fins 3 may be wound into a spiral shape.

The plate 4 is formed of a rectangular plate made of a metal such as iron, stainless steel, or aluminum or a material such as plastic or wood, and the two opposing long sides of the plate 4 are an upper edge and a lower edge, and the upper edge and the lower edge, when the plate 4 is placed upright so that the long sides are up and down in the radial direction of the spirally wound pipe 1, the pipe 1 is fitted and locked for each turn of the spiral. The fitting portions 5, 5 are formed.

The fitting portion 5 is constituted by a substantially semicircular notch into which the pipe 1 can be fitted, as shown in FIG.

Then, a plurality of the spiral pipes 1 are arranged with gaps above and below, and in each gap, a plurality of the plates 4 are approximately evenly distributed around the entire circumference of the spiral, and the above-mentioned plates 4 are arranged in the radial direction. By placing the pipe 1 upright and intervening,
and plates 4 are stacked alternately, and the pipes 1 are respectively locked by the plates 4.

Then, as shown in FIG. 2, the parts of the pipe that are attached to the plate 4, such as the rising part 19 which is the peripheral wall of the water receiving part 18 as the pedestal 11 and the hanging part 20 of the water tank part 17, are made into a spiral shape. By shifting the position from the perfect circle by the amount of winding, it is possible to use a large number of plates 4 all having the same size and shape.

The weight of the upper pipe 1 is supported by the plate 4, and by stacking the pipes in this manner, the spiral pipe group forms a cylindrical body with a hollow center.

At both ends of the spiral pipe 1 formed in this way, for example, the inner end 7 of the winding is connected to a header 9 connected to the inlet of the water to be cooled, and the end 8 of the outer winding is connected to the outlet of the water to be cooled. Connect to the header 10 connected to.

Moreover, a fan 14 rotated by a motor 15 is built in above the center of these stacked spiral pipes 1, that is, above the cavity, and a ventilation part 13 is formed to forcibly exhaust the air inside the cavity. , a water tank part 17 for sprinkling water is provided above the spiral shape of the pipe 1, and a water receiving part 1 for receiving water sprayed onto the pipe 1 from the water tank part 17 is provided below.
8 is provided.

Although not shown, water from the water receiving section 18 or other water source is fed to the water tank section 17 and circulated using a pump and piping.

Further, between the water receiving portion 18 and the spiral pipe 1 at the bottom, there is the plate 4 described above that supports the pipe 1.
A plate 6 is formed without the insertion part 5 at the lower edge of the plate 4, and like the plate 4, a plurality of plates are distributed approximately evenly around the entire circumference of the spiral and are arranged vertically in the radial direction to support the pipe 1. be.

Since this invention is constructed as described above, it is very easy to form the part for heat exchange, that is, the gathering part of the pipes 1 through which the water to be cooled passes, and by changing the headers 9 and 10, the pipes 1 Just by increasing or decreasing the number of and the number of plates 4,
Since the heat exchange capacity can be changed, it can be changed freely depending on the size of the cooler etc. without having to change the design of the cooling tower each time.
Since there is no change in the shape, etc., it is possible to mass produce and reduce costs.
Furthermore, these fixations can be made more rigid.

That is, a pipe 1 with fins 3 formed by sequentially fitting a large number of disk-shaped pieces around the outer periphery or by winding a band-shaped piece in a spiral shape is wound into a sparse spiral shape with a space 2 in the center, By arranging a plurality of pipes 1 with gaps above and below, it is easy to attach the fins 3 themselves to the pipes 1, making it very suitable for mass production, and also has excellent thermal efficiency. For example, when the fin 3 is made of a soft metal such as aluminum, fitting to the plates 4 and 6 can be facilitated by slightly deforming the portions overlapping with the plates 4 and 6, which will be described later.

A plate 4 has fitting portions 5 on the upper and lower edges thereof, which fit and lock the pipe 1 for each turn of the spiral by disposing the pipe 1 vertically in a substantially radial direction. The pipes 1 and the plates 4 are interposed in the gaps between the plurality of pipes 1 by disposing a plurality of the plates 4 approximately evenly distributed around the entire circumference and erected in the radial direction. By stacking them alternately, even if a force is applied from any direction to topple the tower of spiral pipes, the plate whose longitudinal direction is orthogonal to this tower will receive the force applied to the tower. .

In addition, even if a force is applied to the tower in which the spiral pipes are stacked to shift the positions of the upper and lower spiral pipes, the fitting part provided at the lower edge of the plate will fit into the lower pipe, and the upper edge of the plate will The fitting part provided at the top fits into the upper pipe, and since this is continuous vertically, the tower as a whole has a very large resistance against forces that try to topple or collapse the tower. It is something that you have.

Moreover, since the fins are attached to the pipes, by bringing the plate close to the fins, it is possible to prevent the plate from falling over.Also, by making the plate a material with good heat conduction, the thermal efficiency of the cooling tower can be improved. It has the advantage that it can also be improved.

Furthermore, by providing the fitting portions 5 in the plate 4, when stacking the pipes 1, the spiral state of the pipe 1 can be maintained in an accurate state as designed by the gap between the fitting portions 5.

Furthermore, both ends of each pipe 1 are connected to a header 9 connected to the inlet of the water to be cooled and a header 10 connected to the outlet of the cooled water, and a rotating fan 14 is installed above the center of the stacked pipes 1. The built-in ventilation section 13 is further provided with a water tank section 17 for sprinkling water above the spiral shape of the stacked pipes 1, and a water receiver section 18 below to receive the water. The pipe 1 and the plates 4, 6 are held by the rising part 19, which is the peripheral wall, and the hanging part 20 of the water tank part 17, and are positioned relative to the perfect circle by one turn of the spiral pipe 1. Due to the staggered shape, the water to be cooled passing through the pipe 1 is sufficiently cooled by the sprayed water, and is sent to a cooler or the like by each header 9, 10 and circulated.

By configuring the shapes of the rising portion 19 and the hanging portion 20 as described above, the plates 4 can all have the same size and shape, and are very suitable for mass production like the pipe 1. It is.

As explained above, this idea allows the heat exchange capacity to be changed by increasing or decreasing the stacking of pipes and plates, so the parts are compatible and there is no need to change the design each time depending on the size of the cooler. Therefore, the pipes and plates can be mass-produced, and as a result, the cost can be reduced, so it can be provided at a very low cost, and compared to the heat exchanger shown as a conventional example. It can be provided at a much lower price, and has practical advantages such as being robust and easy to assemble.
