  In recent years, a heat exchange ventilator has been adopted as a device for ventilating a room from the viewpoint of energy saving. A heat exchange ventilator is a device that reduces the loss of heat associated with ventilation by exchanging the indoor air temperature and humidity (also referred to as total heat) and the outdoor total heat via a heat exchange element. . The heat exchange element used in the heat exchange ventilator is a cross-flow heat exchange element that exchanges heat by making the supply air flow and the exhaust flow orthogonal to each other, and heat supply by making the supply air flow and the exhaust flow face each other. It classify | categorizes into the counterflow type heat exchange element to replace | exchange.

  For example, as shown in FIG. 22, the cross flow type heat exchange element has a flow path forming plate 602 having a corrugated cross-sectional shape formed on a substrate 601, and the substrate 601 and the flow path forming plate 602 are bonded to each other. The channel plate 604 in which the channel 603 is formed is laminated. Specifically, the cross flow heat exchange element 600 is formed by rotating the flow path plate 604 by rotating 90 ° for each layer. In the flow path plate 604, an air supply flow path plate 604a that takes the outdoor air OA into the room as an air supply SA by an air supply fan (not shown), and an indoor air RA is exhausted EA to the outdoors by an exhaust fan (not shown). And an exhaust passage plate 604b. Between the air supply flow path plate 604a and the exhaust flow path plate 604b, the supply airflow and the exhaust flow flow orthogonally, and the total heat of the supply airflow and the exhaust flow is heat exchanged via the substrate 601.

  For example, as disclosed in Patent Document 1, the counter flow type heat exchange element includes a counter channel portion formed by stacking channel plates, and a first channel connected to one end of the counter channel portion. And a second separation channel portion connected to the other end. The counterflow type heat exchange element disclosed in Patent Document 1 is a unit member that cuts out a rectangular member from a corrugated roll and forms the cutout rectangular member as a counter flow channel portion and first and second separation flow channel portions. Use as The cut-out rectangular member is formed into a unit member suitable for each of the opposing flow channel portion and the first and second separation flow channel portions, and these unit members are joined to create a flow channel plate.

A bonding tape 180 is attached to a position where the first substrate 122 and the third substrate 142 are in contact with each other.

  In order to form the first step portion 123d and the second step portion 133d, for example, after the first flow path forming plate 123 and the second flow path forming plate 133 are formed, the plate surfaces are compressed. There is a method of compressing and forming with a machine, or a method of cutting off part of the first flow path forming plate 123 and the second flow path forming plate 133.

  The width L4 of the bonding tape 180 is formed to be the same width as the width M2 of the first recess 40. The thickness of the bonding tape 180 is formed to be thinner than the depth of the first recess 40. Further, the width M2 of the first recess 40 is determined by the bonding pasted on the plate surface of the second flow path plate 150 when the second flow path plate 150 is overlaid on the first flow path plate 120. It is the same as the width of the tape. The joining tape attached to the opposite side of the second recess 50 also has the same dimensions as the joining tape 180 attached to the first recess 40.

A second recess is also formed at the contact portion with the flow path member 171. The bonding tape attached to the opposite side of the first recess 40 and the second recess 50 also has the same dimensions as the bonding tape 180 of the first flow path plate 120.

  Thus, since the width M2 of the first recess 40 is formed to be the same width as the width L4 of the bonding tape 180, the first flow path plate 120 is laminated on the second flow path plate 150. The bonding tape 180 attached to the second flow path plate 150 is inserted into the first recess 40 formed in the first flow path plate 120 to absorb the thickness of the bonding tape 180, and the flow path plate There is no non-uniformity in the spacing between them.

  According to the present embodiment, the concave portions are formed at the opposite ends of the flow channel forming plate, and the first side flow channel members 131 and 161 and the central flow channel members 121 and 151 are joined using the concave portions. The second side channel members 141 and 171 and the central channel member 121 and 151 were joined. Alternatively, the bonding tape of another flow path substrate can be received using the recess. Therefore, the interval between the flow path plates can be made uniform without using the adjustment tape 190, and the cost can be reduced. Further, unlike the joining method using the joining tape 180 and the adjustment tape 190, when the flow path plates are stacked, the thickness of the tape is not added in the laminating direction, so that the height of the heat exchange element in the laminating direction can be reduced. .
