The present invention relates to a rotary heat exchanger, a manufacturing method thereof, and a manufacturing apparatus thereof.

[0002]

2. Description of the Related Art A rotary heat exchanger used as a heat recovery type ventilation device is conventionally manufactured as follows.

(1) A sheet-shaped article having a constant width is formed into a corrugated shape to form an intermediate shin.

(2) A fixing agent (adhesive) is applied to the entire ridge line portion on the surface side of the middle shin which joins the sheet-shaped liner.
Apply.

(3) The surface of the liner, which is a sheet-like material, is superposed on one side of the ridge line portion of the middle shin, which is coated with the fixing agent, and the middle shin and the liner are bonded via the fixing agent.

(4) Next, a sticking agent is applied to the entire ridge line portion on the other surface of the middle shin.

(5) After that, the laminate of the core and the liner joined by the adhesive is wound up, and at the time of this winding, the adhesive and the liner of the liner are applied via the adhesive applied to the other surface of the core. The ridge line portion of the other surface of the middle shin is joined to the outer surface of the liner in the laminate to form a honeycomb cylindrical body.

(6) The honeycomb cylindrical body thus formed is further impregnated or coated with a bonding agent at both ends in the lengthwise direction of the honeycomb cylindrical body to retain the shape.

In the step (6), the reason why the adhesive agent is applied to both ends of the honeycomb cylindrical body in the longitudinal direction, that is, the openings of the honeycomb cylindrical body is that the heat exchanger made of the honeycomb cylindrical body is rotated. At this time, since the opening of the honeycomb cylindrical body is rubbed against the partition member of the air passage, it is necessary to strengthen the strength of the opening with the adhesive.
