FIG. 2 is an exploded perspective view of the air conditioner outdoor unit 100 according to the embodiment.As shown in FIGS. 1 and 2, the air-conditioning outdoor unit 100 according to the embodiment includes a housing 1 that forms an outer shell. The housing 1 is formed by a front side face panel (front side face panel) 10, a right side face panel (right side face panel) 11, a bottom face panel (bottom face panel) 12 and a top face panel (top face panel) 13. The front panel 10 forms a front side and a left side surface of the housing 1, and is formed by, for example, an L-shaped component when viewed in a plan view. The front panel 10 has a circular air outlet formed therethrough and has a fan guard grill 17 attached thereto covering the air outlet. The right side panel 11 forms a right side surface of the housing 1 and has an opening 11 aformed therethrough. The right side panel 11 has a protective cover 18 fixed to an outer surface thereof, which covers the opening 11 a. The floor panel 12 forms a bottom surface of the housing 1. the floor panel 12 has legs 15 on its lower surface, which are fixed to an installation site. The cover plate 13 forms a cover surface of the housing 1.The inside of the housing 1 is divided into an air sending device space 2 and a machine space 3 by a separator 7. In the air transmission device space 2, a heat exchanger 20, an air transmission fan 21, a motor 22, and a motor bracket 23 are provided. The heat exchanger 20 functions as a condenser during the cooling operation and as an evaporator during the heating operation. The heat exchanger 20 has, for example, an L-shape when viewed in a plan view, and is provided to extend from a rear surface to the left side surface of the housing 1. The heat exchanger 20 is a fin and tube heat exchanger that includes a plurality of fins and heat transfer tubes arranged in parallel, which pass through the plurality of fins and are mounted on an upper surface of the bottom panel 12 so that the heat transfer tubes are held horizontally. The motor holder 23 is a component configured to hold the motor 22 with the air-sending fan 21 mounted on the motor 22, and is provided in front of the heat exchanger 20. The outdoor unit 100 is configured such that activation of the air-sending fan 21 causes air flowing through the heat exchanger 20 to be introduced into and flow through the air-sending fan 20 to be discharged toward a location located in front of the outdoor unit 100. This causes the outdoor unit 100 to be configured such that, for example, during the cooling operation, a refrigerant is cooled by air in the heat exchanger 20, and the air flowing through the heat exchanger 20 is heated by exchanging heat with the refrigerant.In the engine room 3, a compressor 30, a refrigerant pipe 31, and an electric component unit 40 are provided. The compressor 30 is mounted on the upper surface of the bottom plate 12 and compresses refrigerant sent from an indoor unit (not shown). The refrigerant compressed by the compressor 30 is sent to the heat exchanger 20 through the refrigerant pipe 31.
