Air conditioner outdoor unit housing

A separate type air conditioner which includes an outdoor unit and an indoor unit having at least a compressor, a heat exchanger having a peripheral frame with a bore for a screw, and an expansion device, said outdoor and indoor units being connected with each other by refrigerant tubes so that they altogether form a refrigeration cycle of said air conditioner, said outdoor unit comprising:

• a baseplate;
• a housing containing a side wall having a side air intake window, a rear wall having a rear air intake window, and a front wall having an air outlet window, said walls being extended upright from said baseplate;
• and
• a partition board having a peripheral franc and extending upright from said baseplate for separating the internal space of said housing into a fan compartment for accommodating said heat exchanger and a fan for supplying air to said heat exchanger, and a machinery compartment for accommodating said compressor, said peripheral frame of said partition board having a bore fitted to said bore of said heat exchanger when said heat exchanger is extended over said rear air intake window in said rear wall and said partition board is mounted upright on said baseplate, wherein
• said heat exchanger is configured in the form of an L in the top view thereof, and has one section extending over said side air intake window in said side wall, another section connected to said one section by a connecting section extending over said rear air intake window in said rear wall when said heat exchanger is mounted upright on said baseplate;
• said partition board is disposed in front of said heat exchanger when said peripheral frame of said partition board is mounted on the front end of said peripheral frame of said heat exchanger by at least one screw applied from the rear of said heat exchanger;
• said side air inlet window has front and rear vertical columns of horizontal slits and an intermediate strip separating said two columns, said front column of slits facing said one heat exchanger section and said intermediate strip facing said connecting section of said heat exchanger;
• said housing is provided on the ceiling thereof with front and rear plateau regions extending across said ceiling and having widths that match corresponding columns of slits in said side air intake window, said plateau regions defining an intermediate groove therebetween which has the same width as, and is aligned to communicate with, said intermediate strip of said side air intake window.
