  However, in the thing of the said structure, there existed a possibility that the air flow which goes to the heat exchanger 9 from a front may be disturbed by the inverter case 13, and may have a bad influence on heat exchange. Therefore, an outdoor unit as shown in FIG. 5 has been developed to solve such problems. In this outdoor unit, by providing an electrical component box 13 with a heat sink 13a on one side of the housing 5, the air flow from the front to the heat exchanger 9 is improved, and the internal inspection of the electrical component box 13 is performed. The side plate 4a is removed to carry out.

  By the way, even one outdoor unit provided with a plurality of compressors (one having a constant rotational speed and an inverter type capable of controlling the rotational speed) 2 as shown in FIG. 5 can support a plurality of indoor units. However, in some cases, when a plurality of outdoor units are installed close to each other as shown in FIG. 5 or when there is a wall on the side even when there is only one outdoor unit, the side plate 4a can be attached and detached. There was a problem that the internal inspection of the electrical component box 13 could not be performed.

Even if the electrical component box 13 is removable at the time of service inspection, if the electrical component box 13 has a large and heavy configuration, the external part of the electrical component box 13 must be held with a finger. As a result, it has become difficult to hold and has a problem of poor workability at the time of service inspection.
