606, in the case that the quantity of the substrate in converter 607, loop control circuit 608 etc. is 2 or more, from the thickness of thinned electric box
From the perspective of degree, preferably, the plate face of above-mentioned 2 or more substrates is arranged in the same plane.For example, real the 1st
It applies in mode, preferably, the plate face of substrate A1, A2, A3 etc. is arranged in the same plane.
Moreover, in Figure 5, to the refrigerating circulation system figure of the air conditioner 10 of the outdoor unit 1 using above first embodiment
It is illustrated, still, as long as example, the sheet such as outdoor unit 111 of the outdoor unit 11 of the 2nd embodiment of satisfaction, the 3rd embodiment
The outdoor unit of the structure of the outdoor unit of invention can be arbitrary outdoor unit.
In addition, the outdoor unit of the present invention, as the driving power of the outdoor unit, such as may be used single phase ac, 2 phases
The arbitrary power supplys such as exchange, the exchange of 3 phases still use in order to inhibit higher harmonic current and need active filter, active
In the case of 3 phase AC powers of the loop structure of the complexity such as converter, it is particularly possible to reduce the volume of above-mentioned electric box.
