ニットにある。SUMMARY OF THE INVENTION The present invention has been invented to solve the above problems, and its gist is to form a heat exchange chamber and a machine chamber by partitioning the inside of a container casing. A plurality of heat dissipating fins for disposing heat dissipating parts, which are provided in the heat exchanging chamber, a compressor, a control box, etc. In the outdoor unit of the air conditioner, which projects into the heat exchange chamber so as to be perpendicular to the wind passing through the heat exchange chamber, the length of the plurality of radiating fins is changed from the upstream side to the downstream side of the wind. The outdoor unit of the air conditioner is characterized in that the length is gradually increased toward the outside.
