Claims

[Scope of utility model registration request]

A substantially cylindrical main plate having a comb-like mounting groove on its outer periphery is fixed to a rotating shaft by a boss provided at its center, and groove portions are located on the outer periphery of the main plate approximately radially from the center of the main plate. A blade made of corrugated thin plates arranged in a substantially donut shape is provided, and the groove portion of the blade is closed-fitted into the comb-like mounting groove on the outer periphery of the main plate, and the outer periphery of the blade is provided with the A ring-shaped outer circumferential plate is provided that encloses the blade and the main plate, and has comb-teeth-shaped projections having comb-teeth-shaped attachment grooves that alternately protrude from both sides of the inner circumferential portion, and that fit into the outer circumferential ends of the grooves of the blade, Fluid flow generated by the rotation of the main plate, the blade, and the outer circumferential plate as a unit flows through groove portions on both sides of the blade adjacent to each other with the thickness of the blade in between, and heat is exchanged between the two fluids. A heat exchange type blower comprising: a thickness of a comb tooth-like protrusion on the outer circumferential plate in a direction from an outer circumferential end of the blade toward the center, which is different on both sides of the blade.
