Abstract

PURPOSE:To obtain a pipe at a low manufacturing cost by a method in which the pipe is made of a beltlike tape, which is wound spirally with its side edge doubled, and at least a part of the doubled part of the tape is adhered, so that a peripheral wall of the pipe does not attached to each other when a number of pipes are bundled. CONSTITUTION:A pipe A is formed by winding a beltlike tape T spirally. The tape T is doubled at its side edge part 1, and a doubled part 2 is welded by heat to each other. As a thickness of the doubled part 2 is larger than that of the other part, a peripheral wall 3 of the pipe A expands outside at the double part 2. Accordingly, only by bundling a number of the pipes A with the peripheral walls 3 of the adjacent pipes A contacted with each other at the doubled parts 2 where a diameter is large, a prescribed space S can be procured between the peripheral walls 3 excluding the doubled part 2. If the pipe is employed in a humidifier or a heat exchanger, a humidifying area or a heat exchanging area can be obtained widely.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe used for humidification or heat exchange in a bundled state, a humidifier and a heat exchanger using the pipe.

[0002]

2. Description of the Related Art Conventionally, there has been a humidifier built in a heating device or used together with the heating device. In this humidifier, a humidifying element is configured by accommodating a large number of ventilation pipes made of a moisture-permeable porous membrane in an outer tube filled with water to form a humidification element. There was one that tried to humidify the air inside.

In this humidifier, if the above pipes are in close contact with each other, the humidifying area is reduced and the humidifying performance is deteriorated. Conventionally, in order to avoid this, a pipe is formed into a blind shape by a weft thread orthogonal to the pipe, and a predetermined distance is maintained between the peripheral walls of both pipes by the weft thread interposed between the adjacent pipes. There was a humidifying element that was designed to work.

[0004]

However, in this humidifier, there is a problem that the work of forming the pipe in the shape of a blind using the weft thread is very time-consuming and the manufacturing cost is high. On the other hand, a heat exchanger that exchanges heat via the peripheral wall of the pipe in a state where a large number of pipes are bundled has the same problem. Further, the pipe is not limited to the one used in a humidifier or a heat exchanger, and there is a similar problem in a pipe in which a large number of bundles need to be provided with a gap between the peripheral walls.

An object of the present invention is to solve the above-mentioned technical problems and to prevent the peripheral walls from sticking to each other even in a bundled state and to reduce the manufacturing cost, and a humidifier and a heat exchanger using the pipe. Is to provide.

[0006]

In order to achieve the above object, a pipe according to claim 1 is a pipe which is used by bundling a large number and is made of a band-shaped tape material, and a side edge portion of the tape material. It is characterized in that they are spirally wound in a polymerized state, and that at least a part of the polymerized portion of the tape material is adhered.

A humidifier according to a second aspect of the invention is characterized in that a large number of the pipes are bundled and are humidified via the peripheral wall of the pipes. Further, the heat exchanger according to claim 3 is characterized in that a large number of the pipes are bundled and heat is exchanged through the peripheral wall of the pipes.

[0008]

According to the above construction, the thickness of the peripheral wall becomes thicker at the overlapping portion of the tape material and the overlapping portion swells outward,
The maximum outer diameter of the peripheral wall is defined by the outer diameter of the overlapping portion. Therefore, by simply bundling the pipes together, it is possible to secure a predetermined gap between the peripheral walls of the adjacent pipes excluding the overlapping portion. Therefore, it is not necessary to form the pipe in a blind shape as in the conventional case.

When the above pipe is used in a humidifier or a heat exchanger, the distance between the peripheral walls of the pipe can be maintained at a predetermined value by simply bundling the pipes, and a wide humidification area and heat exchange area can be secured. can do.

Embodiments will be described in detail below with reference to the accompanying drawings showing embodiments. FIG. 1 is a side view showing an embodiment of the pipe of the present invention, and FIG. 2 is a sectional view of a main part thereof. With reference to these drawings, the pipe A is configured by spirally winding a strip-shaped tape material T. The side edges 1 of the wound tape T are superposed, and the superposed portion 2 is heat-sealed with the peripheral wall 3 of the pipe A being spirally wound. Since the thickness of this overlapping portion 2 is thicker than the thickness of the other portions, the peripheral wall 3 of the pipe A bulges outward at the overlapping portion 2.

According to this embodiment, by simply bundling a large number of the pipes A, the peripheral walls 3 of the adjacent pipes A are brought into contact with each other at the overlapping portions 2 having a large diameter, and the peripheral walls 3 excluding the overlapping portions 2 are joined together. A predetermined gap S can be secured between them. Therefore, in a device in which it is necessary to secure a predetermined gap between the peripheral walls of a large number of bundled pipes,
When the pipe A is used, the pipe A is used as described above.
Since the above-mentioned gap S can be secured by simply bundling the pipes, it is not necessary to form the pipe in a blind shape as in the conventional case, and the manufacturing cost of the device can be reduced.

The pipe of the present invention is not limited to the above embodiment, and for example, as shown in FIG.
Only the upper edge portion 2a of the overlapping portion 2 may be non-fused to be erected outward, and in this case as well, a large interval between the peripheral walls 3 can be secured. Further, as shown in FIG. 4, it is possible to form a protruding ridge 4 that is raised along the overlapping portion, and in this case, the protruding ridge 4 can secure a large space between the peripheral walls 3.

Further, when the tape material T is thin, etc., a spacer 7 having a circular cross section (see FIG. 5) or a square shape (see FIG. 6) is wound along the outer periphery along the overlapping portion 2. By turning, the gap S can be reliably ensured. FIG. 7 shows a humidifying element of a humidifier B using a large number of pipes A of the embodiment shown in FIG. The material of the pipe A is, for example, a moisture-permeable porous film such as polyethylene or fluororesin, in which an air flow F from a fan (not shown) as a ventilation unit flows. The pipe A is arranged inside a moisture-impermeable outer tube 5 having a cylindrical shape such as a cylindrical shape or a rectangular shape, in which water G is filled, and the inside of the pipe 3 is surrounded by the peripheral wall 3 of the pipe A. The water vapor permeated to humidifies the air flow F inside the pipe A.

According to this embodiment, by simply bundling the pipes A, the interval between the peripheral walls 3 of the adjacent pipes A can be maintained at a predetermined value, and a wide humidification area can be secured. Therefore, it is not necessary to form the pipe in a blind shape as in the conventional case, and the manufacturing cost of the humidifying element and the humidifier can be reduced. Figure 8
Shows a heat exchanger C in which a large number of pipes A of the embodiment of FIG. 1 are bundled and used. The material of the pipe A is, for example, a non-moisture permeable film or a moisture permeable film made of resin, and an air flow F from a fan (not shown) as a ventilation unit is circulated inside the film. The pipe A is arranged in the outer pipe 6 through which the air flow H in the direction opposite to the air flow F is ventilated, and the air flow F and the air flow H exchange heat via the peripheral wall 3 of the pipe A. A liquid flow may be used instead of the air flow H.

According to this embodiment, by simply bundling the pipes A, the interval between the peripheral walls 3 of the adjacent pipes A can be maintained at a predetermined value, and a large heat exchange area can be secured. Therefore, it is not necessary to form the pipe into a blind shape as in the conventional case, and the manufacturing cost of the heat exchanger can be reduced. The present invention is not limited to the above-described embodiments, but the polymerized portion 2 of the tape material T can be adhered by an adhesive, and other various design changes are possible within the scope of the present invention. Can be applied.

[0016]

As described above, according to the pipe of the present invention, by simply bundling, a predetermined gap can be secured between the peripheral walls of the pipe by the overlapping portion having a large diameter. When used in a device that requires a gap between its peripheral walls, the labor of forming a pipe in a blind shape as in the conventional case is unnecessary, and the manufacturing cost of the device can be reduced. it can.

When the pipe is used in a humidifier or heat exchanger, the pipes are simply bundled to secure a predetermined gap between the peripheral walls of the pipes to secure a wide humidification area or heat exchange area. Therefore, it is not necessary to form the pipe in a blind shape as in the conventional case, and the manufacturing cost of the humidifier or the heat exchanger can be reduced.
