Description

[Detailed description of the invention] In this invention, plane paper and corrugated paper are laminated and pasted alternately to form a large number of small holes that pass through both end faces, and two kinds of fluids with different temperatures are placed inside the small holes. The present invention relates to improvements in materials for heat exchangers that exchange heat between two fluids through.

Conventionally, there is a material for heat exchangers that is made by laminating plane paper and corrugated paper alternately and forming a large number of small holes. In the direction of movement, it is necessary to apply strong tension to the flat paper during the adhesive lamination or chemical impregnation process, which can cause tears in the flat paper during the adhesive wrapping process, making the work difficult and causing defective products. In addition, the heat exchange effect is performed by the fluid passing through the small holes, but in this case, the fluid passing through the small holes has a small Ray nozzle number, so it forms a laminar flow, which increases the heat exchange efficiency. There are problems that cannot be improved.

The present invention eliminates the above-mentioned drawbacks, and by arranging an appropriate number of strands between the flat paper and the wavy paper in the direction perpendicular to the length direction of the small through holes, the wavy The purpose is to improve the strength of the material in the direction of movement, and to generate turbulence in the fluid passing through the small through holes for efficient heat exchange.

An embodiment of the present invention will be described below with reference to the drawings. In the drawings, 1 is a plane paper, 2 is a corrugated paper, 3 is a filament, and 4 is a small through hole.

The flat paper 1 and the corrugated paper 2 are film-like materials made of thermoplastic synthetic resins such as polyvinyl chloride and polyethylene, and other synthetic resin materials, and papers made of fibrous materials such as asbelt paper, glass fiber paper, and kraft paper. The paper 1 and the corrugated paper 2 may be made of the same material or may be a combination of different materials.

The fibers 3 are made of vegetable threads such as cotton threads, animal threads such as silk threads, synthetic threads such as nylon threads, vinyl chloride threads, polyethylene threads, polypropylene threads, and 0,0
A fine metal wire with a diameter of about 1 to 0.05 mm may be used, and various threads may be used in combination.

In this case, as described above, a plane paper 1 and a wavy paper 2 are pasted together with an adhesive, a large number of small through holes 4 are formed between the plane paper 1 and the wavy paper 2, and the direction of the small through holes 4 is as follows. The fibers 3 are arranged and sandwiched at appropriate intervals so as to be orthogonal to each other.

The heat exchanger material of the present invention thus obtained is, for example, the third
As shown in the figure, the outer surface of a cylindrical core is crimped several times and used in a rotary heat exchanger.

As is well known, there are two types of heat: sensible heat and latent heat.

The sum of sensible heat and latent heat is called total heat.

When the materials mentioned above are used for the plain paper 1 and the corrugated paper 2, a sensible heat exchanger is obtained, and when the plain paper 1 and/or the corrugated paper 2 are impregnated with a moisture absorbent, a total heat exchanger is obtained.

In this case, as mentioned above, the fibers 3 are arranged perpendicularly to the direction of the small through hole 4.
Since a large number of sheets are arranged and sandwiched at appropriate intervals, when the flat paper 1 and the corrugated paper 2 are successively pasted together, as in the past, the flat paper 1 is insufficient in strength and may be torn due to the tension applied during processing. The strength of the product is improved without fear, and when using a heat exchanger, the small through holes 4 are
The effect is that efficient heat exchange can be carried out by creating turbulence in the fluid passing through the chamber and increasing contact between the fluid having a mutual temperature difference and the small through-hole wall.

According to experiments, when the size of the small holes and the paper material were all the same, the heat exchange efficiency increased by approximately 5% when the fibers 3 were provided compared to when the fibers 3 were not provided.
