Each of these has a basic structure in which a partition plate having heat conductivity and moisture permeability (which may have only heat conductivity) is superposed in a plurality of layers at predetermined intervals with a space plate interposed therebetween. There is. The partition plate is a rectangular flat plate, and the spacing plate is a corrugated plate with a sawtooth or sinusoidal waveform whose projection plane matches the partition plate.

調分野において大きな貢献を果すに至っている。In the heat exchanger having the above-mentioned structure, the primary air flow and the secondary air flow are connected to the heat exchange passages of the two systems which are alternately formed for each layer and are independent of each other, so that the primary air flow and the secondary air flow are connected. In between, the temperature and humidity of each of the air streams are exchanged simultaneously and continuously. Japanese Patent Publication No. 51-42334, Japanese Patent Publication No. 62-35596, and Japanese Patent Laid-Open Nos. 6-109395 and 6
As disclosed in Japanese Patent No. 123579, many innovations have been made on a partition plate that is the main component of the heat exchange function, and technological innovation has advanced to the point where high heat exchange efficiency can be obtained, which has made a great contribution to the air conditioning field. There is.

Many efforts and trials have been made to improve heat exchange efficiency by improving the material and reducing the wall thickness.
However, since the heat exchanger as described above originally has a simple basic structure and the degree of completion is already quite high, it is no longer possible to achieve the above-mentioned problems in the direction of improving the material of the partition plate and reducing the wall thickness. Almost impossible.

No. 8, Japanese Utility Model Publication No. 5-52568, Japanese Utility Model Publication No. 5-5
A technique has been proposed in the direction of greatly expanding the effective area for heat exchange as shown in Japanese Patent No. 2567. In Japanese Patent Laid-Open No. 60-2888, a corrugated plate is piled up so that the peak portions are alternately in contact with each other, and a spacer is sandwiched at both ends in the same direction and laminated. Although the heat transfer area is wide because the heat transfer surface is a corrugated plate and not a flat plate, one of the passages is linear, but many of the passages are orthogonal to the corrugations and have irregularities, which makes it a primary fluid. The performance cannot be expected so much because the secondary fluids flow in completely different ways and the heat exchange obstruction points formed by adhesion are wide. In addition, it is difficult to accurately match all the crests of the corrugated sheet with a corrugated sheet having a small pitch, and the productivity is low.

The one disclosed in Japanese Patent No. 52567 is configured by stacking corrugated element sheets 101 so that corrugations intersect each other as shown in FIG. 9 and alternately closing the valleys of the end faces of the element sheet 101. Is. This can be constituted only by the corrugated element sheet 101 without a member corresponding to the spacing plate, and the effective area for heat exchange is remarkably widened, which is effective for high performance and compactness.

い。The heat exchanger in which the above spacers and spacers are eliminated and only corrugated plates are laminated and which is expected to have high performance, has a serious problem to be overcome. That is,
It is actually very difficult to alternately close the valleys of the end face of the element sheet 101, and in this type of heat exchanger applied to an air conditioner, the corrugated height and pitch of the element sheet 101 are each about 2.5 mm. Since it is as small as about 4 to 6 mm and its thickness is as thin as about 100 gramm, it is almost impossible to close each valley. In Japanese Utility Model Laid-Open No. 52525/1993, the flat portion 102 is formed so that the closing portion is also integrally formed by a mold. However, in the closing portion equivalent to the thin element sheet 101, pressure due to air blowing is applied. The closed part may open.

It is to obtain a manufacturing method that can reduce the cost of the heat exchanger.

がり、熱交換性能を向上させる方向に働く。The heat exchanger 1 as a hierarchical structure can be constructed by stacking the corrugated plates 2 having the above-described structure so that the corrugated plates 2 do not have a structural dependency and are simply crossed with the corrugations. In this heat exchanger 1, as shown in FIG. 1, primary fluid passages 6 are formed alternately for each layer and are independent of each other.
By connecting the primary fluid a and the secondary fluid b to the secondary fluid passage 7 and the secondary fluid channel 7 from one opening end, respectively, the fluid flow between the primary fluid a and the secondary fluid b is not interrupted. The temperature and humidity held can be continuously changed. In both of the primary fluid passage 6 and the secondary fluid passage 7, the corrugated corrugated plates 2 adjacent to each other in the direction intersecting the flow direction face the inside thereof, so that both the passing primary fluid a and the secondary fluid b are passed. Is turbulent. The turbulent flow of the primary fluid a and the secondary fluid b leads to an increase in the number of contact with the heat transfer surface, which works to improve the heat exchange performance.

交換器１としての信頼性は高いものとなる。Since the heat transfer area functioning for heat exchange in the heat exchanger 1 is due to the corrugated plate 2, it can be increased to about 150% in the same projection plane as compared with the conventional flat plate type laminated heat exchanger. That is, the corrugated board 2
Since a vast increase in the heat transfer area obtained by multiplying the increase in the heat transfer area per sheet by the number of laminated layers is obtained, the heat exchanger has a very high performance. Although the opening area of the inlet and outlet of the primary fluid passage 6 and the secondary fluid passage 7 is narrowed because one side in the stacking direction is closed, it is compact because it is composed only of the corrugated plate 2 that functions for heat exchange, and the material is also a spacer. It is 30% to 40% less than the conventional one. Particularly, the closed portion 4 made of resin has a stable structure that is not peeled off by the pressure of the blown air, and can maintain high airtightness, so that the reliability of the heat exchanger 1 is high.
