Structure of the Invention The heat exchange type blower of the present invention includes a blade, an outer peripheral plate, and a partition plate, and a flexible sealing material having a substantially ring shape and a substantially V-shaped cross section is fixed to the outer peripheral plate,
The partition plate has a sliding portion located at the center of the substantially V-shaped cross section of the sealing material, and is swingable in the front and rear directions, so that the heat exchange type blower rotates. Even if the pressure on both sides of the partition plate is different, the sliding part is always located at the center of the approximately V-shaped cross section of the sealing material, and the sliding resistance between the sealing material and the sliding part during rotation can be reduced. This reduces torque and improves the durability of the sealing material.

In the above configuration, when the heat exchange type blower rotates, the sealing material 15 slides between and seals the sliding part 30 due to centrifugal force and wind force, but the sealing material 15 is sealed between the circulating air 26 side and the cooling air 27 side. If the loads are different and Pa>Pb as shown in FIG. Because of the presence of the sliding part 30 as shown in FIG.
swings toward the cooling air 27 side due to the sliding resistance difference (pressure difference) and pressure difference, and the sealing material 15 and the sliding portion 30 slide at a position where the sliding resistance becomes uniform. That is, the sliding portion 30 is always located at the center of the substantially V-shaped cross section of the sealing material 15 and slides thereon.

Therefore, the sliding resistance between the sealing material 15 and the sliding part 30 becomes uniform in the A part and the B part, and is smaller than that in the conventional non-uniform case, and the rotational torque can be reduced, and the sliding resistance of the sealing material 15 is This has the effect of improving durability. In addition, even if the load on both sides of the blade 11 changes, the sliding resistance between the sliding part 30 and the sealing material 15 is always uniform, so the two types of airflow flowing through the grooves on both sides of the blade 11 do not mix. This has the effect of improving heat exchange efficiency.
