  • Patent number: 5257902
    Abstract: A blower includes a plurality of rotatable impeller vanes operable to impel air. The impeller vanes create an air pressure differential thereacross when rotated, and each of the impeller vanes has a porous central portion made of sintered resin material. The porous central portion has a plurality of pores therein which permit a portion of air to pass through the porous central portion from a relatively high air pressure side to a relatively low air pressure side of the impeller vanes. Each of the impeller vanes also has a non-porous portion surrounding the porous central portion. The non-porous portion is made of a solid resin material which prevents air from passing therethrough.

  • Patent number: 4907646
    Abstract: A heat exchanger has groups of cutouts provided on tabular fin surfaces, projecting in the direction of arrangement of the fins. Each of the cutouts has two opposed openings in the main direction of air flow as well as two leg portions that not parallel with the main direction of air flow, the cutouts being formed on the tabular fin surfaces alternately on the front and rear sides with a fin base portion placed therebetween. The heat exchanger substantially reduces heat resistance between the air and the fin surfaces and ventilation resistance when the humidity is high, and excels in noise characteristics since the configuration of each cutout provided on the fin surface on the air inlet side of a cross flow fan is changed.
