Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

The invention claimed is: 1. A heat-exchanger fixing plate to fix 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 comprising: 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 formed separately from the heat-exchanger support portion, fitted to the heat-exchanger support portion, and detachably engaged with the heat-exchanger support portion, the housing-panel fixing portion being fastened with a screw to the housing panel such that the heat exchanger is fixed to the housing panel, the housing-panel fixing portion being made of material having a higher mechanical strength than a mechanical strength of material of which the heat-exchanger support portion is made, the heat-exchanger support portion being made of the material having a lower friction coefficient than a friction coefficient of the material of which the housing-panel fixing portion is made. 2. The heat-exchanger fixing plate of claim 1 , wherein the housing-panel fixing portion is made of ABS resin. 3. The heat-exchanger fixing plate of claim 1 , wherein the heat-exchanger support portion is made of PP resin. 4. An indoor unit of an air-conditioning apparatus, the indoor unit comprising the heat-exchanger fixing plate of claim 1 . 5. The heat-exchanger fixing plate of claim 1 , wherein the housing-panel fixing portion and the heat-exchanger support portion each include a respective plurality of engagement latches and engagement portions adapted to fit the housing-panel fixing portion to the heat-exchanger support portion.
