Description

[Detailed Description of the Invention] The present invention relates to a heat exchanger that is very easy to manufacture and has excellent heat exchange efficiency.

Conventional heat exchangers generally have the disadvantage that if you try to improve the heat exchange rate, the configuration becomes complicated and the manufacturing cost increases, and if you try to simplify the configuration, the heat exchange rate decreases. .

The present invention aims to solve these conventional drawbacks, and provides a heat exchanger that has a simple configuration, has an excellent heat exchange efficiency, and is particularly suitable for low-pressure gases.

In the present invention, a plurality of rectangular corrugated plates of the same size are stacked so that the directions of the waves are orthogonal to each other to form alternately orthogonal flow channels between the corrugated plates, and at the end of each corrugated plate, A means for closing the openings is provided so that the channels perpendicular to each other do not communicate with each other, and this means cuts out the ends of each corrugated sheet in a shape that matches the corrugations of the adjacent corrugated sheets, or fills in the spaces between opposing corrugations. It is constructed by using shaped pads, and is provided with a clamping means for clamping a block made of stacked corrugated plates in the thickness direction, and a fluid supply port and a discharge port are provided on corresponding sides of the block, respectively. It is.

Hereinafter, the present invention will be explained with reference to drawings of embodiments.

The heat exchanger of the present invention has, for example, a first component as a component of the heat transfer section.
A corrugated plate 2 as shown in Figure A is used.

This corrugated plate 2 has corrugated notches 20 formed on both sides thereof,
A plurality of pieces of the same shape are stacked one on top of the other so that their waves are perpendicular to each other to form a heat transfer block as shown in the opening of FIG.

Alternatively, as the waveform 2, the pad 3 having the waveform unevenness on the upper surface is placed on the side of the waveform 2, as shown in FIG. match.

Next, a flat plate 5 of the same size as the corrugated plate 2 as shown in FIG.
, 5 sandwich the corrugated plate block from above and below, the four sides are tightened with bolts 6, and members 7 which come into contact with the end surfaces of the pads 3 are arranged at the four corners.

As a result, a heat transfer section is formed, and in this heat transfer section, channels are formed which are alternately orthogonal to each other in the horizontal direction.

Next, this heat transfer part 30 is mounted in the outer box 8 so that its corner is located at the center of the side of the outer box 8.

As shown in FIG. 5, a U-shaped holding member 9 is attached to the outer box 8, and the corner members 7 of the heat transfer portion 30 are fitted into this to connect the two.

Further, the upper and lower surfaces of the outer box 8 are covered with appropriate plates (not shown).

In this configuration, air supply from the inlet 12 passes through the heat transfer section 30 and is discharged from the outlet 11, while air supply from the inlet 13 passes through the heat transfer section 30 and is discharged from the discharge port 14. Heat exchange occurs while both supply air passes through the heat transfer section 30 at right angles to each other.

In the heat transfer section 30, as shown in FIG. 6, a horizontal channel 4a is formed between the corrugated plate 2a and the corrugated plate 2b below it, and A flow path 4b is formed between the plate 2C and the flow path 4b in a direction perpendicular to the flow path 4a, that is, a direction perpendicular to the plane of the paper, and in the same manner, flow paths that are perpendicular to each other are formed alternately.

The bottom surface of these channels is wavy in the direction transverse to the fluid's traveling direction, and the top surface is wavy in the fluid's traveling direction, making the shape of the channel complicated, resulting in turbulent flow. Good heat exchange takes place.

Furthermore, since it is made of stacked corrugated plates, a large heat transfer area is formed with a relatively compact structure.

As explained above, the heat exchanger of the present invention is constructed by stacking corrugated plates, and is much easier to manufacture than conventional heat exchanger tube types, and is particularly suitable for low-pressure gas heat exchangers. It is an excellent product.
