Abstract

PROBLEM TO BE SOLVED: To provide excellent cooling efficiency with a simple structure by bringing the protrusion of a sheet into contact with the protrusion of the adjacent sheet, opposing the recesses, and so superposing the sheets that the edge sides of the sheet are butted, thereby providing high and low temperature medium channels. SOLUTION: When the front surface of a first sheet is so superposed with the front surface of a second sheet 11 that the edge sides 12 of the sheets butted to each other, the first protrusion and first partition protrusion 16a are brought into contact with the first part protrusion 18a, the first coupling protrusion 19a has a gap from the front surface of the first sheet, thereby forming a zigzag-like snaking passage is formed between the front surface of the first sheet and the front surface of the second sheet 11. This passage communicates with the first cooling introducing hole 13A and discharging hole 13B. The cutout 15 of the sheet 11 forms part of the opening for introducing, for example, sample water of a high-temperature medium, and forms the part of the opening for externally discharging the sample water.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat exchange device, and more particularly to a heat exchange device which is excellent in heat exchange efficiency, can be easily manufactured, and is small in size but excellent in heat transfer efficiency.

[0002]

2. Description of the Related Art When boiler water is sampled by a sampling device, it is necessary to cool it with a cooling device because the sample is hot.

Conventionally, as a cooling device, a small diameter pipe is inserted into a large diameter pipe and cooling water is passed between the large diameter pipe and the small diameter pipe.
A double-tube cooling device in which a liquid to be cooled is passed through a small-diameter pipe to cause the cooling water and the liquid to be cooled to flow countercurrently, and a cooling medium filled in a cooling tank is coiled around. An immersion type cooling device and the like in which a cooling liquid flow corrugated pipe is arranged have been known.

However, in the double pipe cooling device, the surface area of the small diameter pipe becomes the heat transfer area for cooling, and therefore the length of the double pipe must be made sufficiently large to enhance the cooling efficiency. However, the larger the length of the double pipe, the larger the shape of the cooling device itself. Therefore, the double-tube cooling device is naturally limited in performing a cooling operation with high cooling efficiency in a small space. Moreover, in the double-pipe cooling device, the double pipe is formed by inserting the small-diameter pipe into the large-diameter pipe, so that the manufacturing process is complicated, and a special device for manufacturing the double-pipe is also used. is necessary. Further, in the immersion type cooling device, like the double pipe cooling device, in order to increase the heat transfer area, it is necessary to take a large flow length of the liquid flow pipe to be cooled, and a dead tank is used. Due to the space, there is a problem that the space occupied by the cooling device inevitably becomes large.

-Basic Unit-A basic unit is formed using the first to fourth sheets 1 to 31. That is, the front surface of the first sheet 1 and the front surface of the second sheet 11 are overlapped with each other such that the edge portions 2 and 12 thereof abut each other. By this superposition, the first convex portion 4
A and the first partition convex portion 16a and the first partial convex portion 18a are aligned to form a partition wall inside. Second sheet 11
The first connecting convex portion 19a in does not contact the front surface of the first sheet 1. Therefore, by overlapping the front surface of the first sheet 1 and the front surface of the second sheet 11, the first cooling water flow passage is formed.

The back of the second seat 11 and the third seat 2
1 and the back surface of No. 1 are overlapped so that the mutual edge portions 12 and 22 correspond to each other. By this superposition, the first meandering recess 17b and the second meandering recess 27b form a first sample water flow passage.

The second connecting convex portion 29a of the third sheet 21 does not contact the front surface of the fourth sheet 31. Therefore, the second cooling water flow passage is formed by overlapping the front surface of the third sheet 21 and the front surface of the fourth sheet 31.

By overlapping the first to fourth sheets 1 to 31, a first cooling water flow passage and a second cooling water flow passage are formed, and in the first cooling water flow passage and the second cooling water flow passage. One first sample water flow passage is formed which meanders in a zigzag manner when sandwiched.

This basic unit alone can be a heat exchange device. That is, when the cooling water is introduced from the first cooling water introducing hole and the second cooling water introducing hole and the sample water is introduced from the first sample water introducing hole, the cooling water and the sample water flow countercurrently. Is cooled while flowing through the first sample water flow passage, and the cooled sample water is discharged from the first sample water outlet.

In order to secure the first sample flow passage necessary for sufficiently cooling the sample water with the cooling water, each sheet is designed so that the first meandering recess 17b and the second meandering recess 27b are elongated. Is good.

-Multiple Assembly of Basic Units- It is preferable to connect a plurality of basic units when the predetermined heat exchange effect cannot be achieved by the basic units alone. In this case, connecting means connecting the cooling water flow passages in the n base units to each other, and also connecting the sample water flow passages in the n base units to each other, thereby physically uniting the base units. It does not mean that. However, if it is intended to make the entire apparatus compact, it is preferable to physically combine the basic units, for example, the back surface of the fourth seat 31 and the second basic unit in the first basic unit. The rear surface of the first sheet 1 in the unit is overlaid, and thereafter, the rear surface of the first sheet 1 of the nth basic unit and the fourth surface of the (n-1) th basic unit are similarly processed.
It is better to overlap the back of the sheet 31 of.

How many basic units are connected depends on what kind of medium heat exchange is achieved by this heat exchange device.

(Modification) The planar shape of the first to fourth sheets is not limited to the rectangular shape as in the above-described embodiment, but an appropriate shape can be adopted. For example, a square shape, a diamond shape, a polygonal shape, a circular shape, or the like as the planar shape of the sheet can be appropriately adopted depending on the location of the heat exchange device, the combination with other devices, and the like.

The edges of the first to fourth sheets are not limited to the edges of each sheet, and may be inside the edges of the sheets. If the edge portion is formed so that the edge portion of one sheet and the edge portion of the other sheet abut each other to form a closed space for forming the cooling water flow passage and the sample water flow passage. good.

The notch provided at the edge of the sheet is not limited to having a circular cross section, and may have a rectangular shape.

According to the present invention, the sheets having a simple structure obtained by forming the sheets can be easily assembled by superposing them, and the number of sheets to be superposed can be changed according to the scale of heat exchange. By being variable, it is possible to provide a heat exchanging device capable of making detailed correspondence according to the scale of heat exchange.

Moreover, according to this heat exchange device, it is possible to provide a small-sized heat exchange device having a simple structure and excellent cooling efficiency. According to the present invention, it is possible to provide a heat exchange device that can be easily manufactured using a material having a simple structure. According to the present invention, it is possible to provide a heat exchange device which is small in size despite having a large heat exchange area.
