## Abstract

An outdoor unit of an air-conditioning apparatus includes a housing forming an outline of the outdoor unit, a partition plate extending from a front surface toward a rear surface of the housing and partitioning an interior of the housing into an air-sending device chamber and a machine chamber, a heat exchanger disposed in the air-sending device chamber and along an end portion located at the rear surface of the housing, and a holder mounted on the heat exchanger and accommodating a temperature-measurement unit that measures an outside air temperature. The partition plate includes a first flat portion disposed with a space between a rear surface of the first flat portion and the heat exchanger and extending in a longitudinal direction of the heat exchanger, and a second flat portion projecting from a side edge portion of the first flat portion toward the heat exchanger.

## Claims

### Claim 1

An outdoor unit of an air-conditioning apparatus, the outdoor unit comprising:
a housing forming an outline of the outdoor unit;
a partition plate extending from a front surface of the housing toward a rear surface of the housing and partitioning an interior of the housing into an air-sending device chamber and a machine chamber;
a heat exchanger disposed in the air-sending device chamber and along an end portion located at the rear surface of the housing; and
a holder mounted on the heat exchanger and accommodating a temperature-measurement unit configured to measure an outside air temperature,
the partition plate including
a first flat portion disposed with a space between a rear surface of the first flat portion and the heat exchanger and extending in a longitudinal direction of the heat exchanger, and
a second flat portion projecting from a side edge portion of the first flat portion toward the heat exchanger,
the holder including
an accommodating unit holding the temperature-measurement unit, and
a hook unit formed continuous with the accommodating unit, the hook unit extending across a top surface of the heat exchanger and being hooked to the first flat portion.

### Claim 2 (depends on 1)

The outdoor unit of an air-conditioning apparatus of claim 1, wherein the partition plate further includes a third flat portion projecting from a side edge portion of the second flat portion in the longitudinal direction of the heat exchanger.

### Claim 3 (depends on 1)

The outdoor unit of an air-conditioning apparatus of claim 1,
wherein the hook unit of the holder includes
an extended-surface portion extending from the accommodating unit, the extended-surface portion being in contact with a rear surface of the heat exchanger,
a top-surface portion extending and being bent from an end portion of the extended-surface portion and placed on the top surface of the heat exchanger, and
a hook portion extending and being bent from an end portion of the top-surface portion and hooked to the first flat portion, and
wherein the hook portion has an end portion that is inclined outward.
