Outdoor unit

Abstract

The invention provides an outdoor unit for reducing the front projection area of a distribution box and causing the flow of the cooling air in a cooling machine room to be smooth. The distribution box of the outdoor unit is provided with a distribution unit supporting plate arranged at the front side of the machine room and extending towards the width direction of the machine room, the distribution unit supporting plate comprises a plate portion extending to a heat exchange room from the front of the machine room nearby the outside surface of the machine room and a sloping plate portion sloping from the plate portion to the front side of the heat exchange room and extending to a spacing plate, the front of the plate portion is provided with a first distribution substrate composing a firstunit, the front of the sloping plate portion is provided with a second distribution substrate composing a second unit, the spacing plate at the back side of the sloping plate portion is provided witha spacing plate sloping portion along the sloping plate portion roughly, a blind hole space (SP) enclosed by the spacing plate sloping portion and the sloping plate portion is provided with a radiator releasing the heat emitted by the second distribution unit, and the sloping portion of the spacing plate is provided with vents for leading the cooling air which flows at the back of the plate portion and the sloping plate portion to cool the radiator to the negative pressure side of the blower of the heat exchange room.

Description

technical field [0001] The present invention relates to an outdoor unit in which the inside of the unit housing is divided longitudinally by partition plates into a heat exchange chamber and a machine room, the heat exchange room houses a heat exchanger and a blower, and the machine room houses a compressor and a power distribution box. Background technique [0002] Some of the outdoor units of the air conditioner divide the inside of the unit casing into a heat exchange chamber and a machine room by partitioning vertically. The heat exchange room houses a heat exchanger and a blower, and the machine room houses a compressor and a power distribution box. [0003] Generally, this kind of power distribution box removes the front panel of the outdoor unit for maintenance work. Therefore, for example, when the power distribution box is set as a plate member extending substantially straight in the width direction of the machine room, as long as the power distribution product is a...

AI Technical Summary

Problems solved by technology

[0007] Conventionally, the outside air is vented into the machine room to cool the power distribution products in the power distribution box. However, if the power distribution box is arranged on the front side of the machine room as mentioned above, it is sometimes difficult to smoothly exchange the cooling air in the machine room with the heat. Indoor exhaust, the flow of cooling air may deteriorate
