Abstract
A heat exchanger includes a plurality of flow pass elements. Each flow pass element includes a partition member that is a moisture permeable sheet shaped member, and a frame forming an air flow path by joining to the partition member. The heat exchanger is configured by stacking the plurality of flow pass elements. In each of the plurality of flow pass elements, the partition member is joined to the frame in direction contact.
Claims9
A heat exchanger comprising:
- a plurality of flow pass elements, each flow pass element including
- a partition member that is a moisture permeable sheet shaped member, and
- a frame forming an air flow path by joining to the partition member,
- the heat exchanger being configured by stacking the plurality of flow pass elements, and
- in each of the plurality of flow pass elements, the partition member being joined to the frame in direction contact.

A method for manufacturing a heat exchanger, the method comprising:
- a first step of assembling a plurality of flow pass elements, each flow pass element being assembled by joining a partition member to a frame forming an air flow path, the partition member being a moisture permeable sheet shaped member;
- and
- a second step of stacking the plurality of flow pass elements assembled in the first step,
- each partition member including a porous base that is sheet shaped and a moisture permeable layer covering a surface of the porous base, and
- each flow pass element being assembled by
- stacking the partition member on the frame such that the moisture permeable layer faces the frame,
- temporally dissolving or softening a portion of the moisture permeable layer facing the frame, and
- solidifying the portion of the moisture permeable layer which has been temporally dissolved or softened, to join the partition member to the frame.
