  • Patent number: 11940174
    Abstract: A heat-exchanger fixing plate fixes a side portion of a heat exchanger to a housing panel of an air-conditioning apparatus, the heat exchanger including a heat radiation fin and a heat transfer tube. The heat-exchanger fixing plate includes a heat-exchanger support portion facing the side portion of the heat exchanger, and having an insertion hole through which a hairpin portion of the heat transfer tube of the heat exchanger is inserted; and a housing-panel fixing portion separate from and fitted to the heat-exchanger support portion fastened with a screw to the housing panel such that the heat exchanger is fixed to the housing panel. The housing-panel fixing portion is made of material having a higher mechanical strength than that of the heat-exchanger support portion, and the heat-exchanger support portion is made of the material having a lower friction coefficient than that of the housing-panel fixing portion.
