The air conditioner according to the present embodiment includes an outdoor unit 10 and an indoor unit (not shown), and performs a cooling operation and a heating operation by flowing a refrigerant through a refrigerant circuit connected by a refrigerant pipe. The outdoor unit 10 is installed outside, exchanges heat with outdoor air, condenses the refrigerant during the cooling operation and releases heat to the outside air, and evaporates the refrigerant during the heating operation and takes in heat from the outside air. In addition, the directions such as up and down and left and right described below indicate directions when the outdoor unit 10 is viewed from the front side in a state where the outdoor unit 10 is installed.

  FIG. 1 is a perspective view of the outdoor unit 10. The outdoor unit 10 includes a substantially rectangular parallelepiped box-shaped unit case (housing) 11, and the unit case 11 includes a bottom plate 12, a ceiling panel 13, a front panel 14, and an outer plate 15. The inside of the unit case 11 is partitioned vertically by a partition plate 16 erected on the bottom plate 12, and is divided into a heat exchange chamber R1 and a machine chamber R2. The front panel 14 includes a first front panel 14A and a second front panel 14B that are divided into left and right parts with a partition plate 16 as a boundary. By removing the first front panel 14A, the operator can perform maintenance work on components in the heat exchange chamber R1 from the front side of the outdoor unit 10, and by removing the second front panel 14B, the operator can perform outdoor work. Maintenance work of parts in the machine room R2 can be performed from the front side of the unit 10.

  In addition, the first front panel 14A on the heat exchange chamber R1 side is formed with two air outlets 28 and 28 that blow out the air heat-exchanged inside the heat exchange chamber R1 in the vertical direction. The air outlets 28 and 28 are each covered with a net-like fan guard 29. Although not shown, the air outlets 28 and 28 are covered with, for example, a round flange-shaped fan cover, and a blower 22 described later is provided in the opening of the fan cover.

  FIG. 2 is a perspective view of the outdoor unit 10 with the ceiling panel 13, the front panel 14, and the outer plate 15 removed. The inside of the unit case 11 is divided into a heat exchange chamber R1 and a machine room R2 by a partition plate 16 standing on the bottom plate 12. As shown in FIG. 2, the heat exchanger 21 accommodates the heat exchanger 21 on the back side and the blowers 22 and 22 arranged in the vertical direction on the front side. The heat exchanger 21 is formed by being bent into a substantially L shape when viewed from above, and is disposed along the back surface from the left side surface (outer side surface) of the heat exchange chamber R1. Thus, the heat exchanger 21 forms the left side surface and the back surface of the heat exchange chamber R1 (that is, the unit case 11), and the entire exposed surface from the left side surface to the back surface functions as a ventilation path (suction port). Although not shown, the surface of the heat exchanger 21 is covered with a finger made of a resin net or the like in order to prevent a human body or the like from contacting the heat exchanger 21.

  The electrical unit includes: a first substrate disposed substantially horizontally with the partition plate body directly above the partition plate; a second substrate disposed in a substantially T shape with respect to the first substrate; 1 substrate, and a substrate holder that is detachably supported by the support member integrally with a heat sink that dissipates heat generated by the electrical components mounted on the first substrate,
  The support member faces the heat exchange chamber through an opening through which the heat sink communicates with the heat exchange chamber and the machine chamber, and the substrate holder is disposed so that the first substrate is disposed in the machine chamber. To support
  An outdoor unit of an air conditioner characterized by that. The outdoor unit of the air conditioner according to claim 1 or 2, wherein a convex portion that fits into the recess is provided on a tube plate of the heat exchanger. The support member includes a plate-like member that extends to the partition plate body and projects to the back side in the height direction, and the recess extends the plate-like member along the back surface of the partition plate body. The convex portion is formed by bending the inner edge of the casing of the tube plate in a substantially L shape on the heat exchange chamber side. The outdoor unit of the air conditioning apparatus according to claim 3 . The air conditioner according to claim 4 , wherein the convex portion is fitted into the concave portion, the front surface of the edge of the plate-like member and the rear surface of the convex portion are brought into contact with each other, and are fixed with screws. The outdoor unit of the device.
