In addition, above-mentioned power inverter 1 utilizes next door 130 to be divided into high heating part 11 and low heating part 12, but next door 130 might not be set.And, in the situation that be provided with next door 130, can be not with the space of the rear side of the substrate of baseplate part 4 and power baseplate part 600, next door be set being formed with output as described above yet yet, but only in the face side of substrate, erects next door is set.Perhaps, also can be only in the spatial placement next door of the rear side of substrate.
And, above-mentioned power inverter 1 will be divided into high heating part 11 and low heating part 12 two parts in housing 10, but also can for example with hanging down heating part 12, be divided into the first low heating part and the second low heating part, form high heating part 11 in central authorities, in the mode that clips described high heating part 11, configure the first low heating part and the second low heating part.
