(C) dividing plate
The dividing plate 53 of this example is made of upper baffle plate 53a and two tabular components of lower partition 53b.Dividing plate 53a, the 53b of this example are formed from a resin.
And, upper baffle plate 53a and lower partition 53b up and down between form the window portion 57 that front space C is communicated with inner space D.
(D) configuration of electric parts
Next, adopt Fig. 6～Fig. 9 that the configuration of electric parts case 15 internal electric parts is described.Here, Fig. 8 is that explanation electric parts case 15 takes off the stereogram that covers the later state of member 52.Fig. 9 is the exploded perspective view that explanation electric parts case 15 takes off the later state of dividing plate 53.
Main electric parts in the electric parts case 15 comprise: light current parts such as noise filter 62a, the 62b that forceful electric power part such as converter 61a, the 61b of compressor 13a and fan 14 usefulness, choke 61c and converter 61a, 61b use, terminal board 63a～63b, control substrate 64.Wherein converter 61a, 61b and choke 61c are the height heating parts that caloric value is big in the operation process, and control substrate 64 then is the little low heating part of caloric value in the operation process.
As promoting cooling in the operation process, will be arranged in the inner space D as generate heat converter 61a, 61b and the choke 61c of part of height.Particularly, converter 61a is configured on the position corresponding with fin 54, and converter 61b is configured on the position corresponding with fin 55, and choke 61c is configured in the upside of converter 61a.On the other hand, will be configured among the front space C, be directly fixed on (this example is upper baffle plate 53a) on the dividing plate 53 as the control substrate 64 of low heating part.That is, in electric parts case 15, high heating part is separated to be configured among front space C and the inner space D with low heating part.
In addition, consider that outdoor unit 1 is provided with after, to terminal board 63a～63b and control substrate 64 (first electric parts) the processing frequency higher, with terminal board 63a～63b and control substrate 64 be disposed among the front space C.Particularly, terminal board 63a～63b is installed on the lower partition 53b, and control substrate 64 is installed on the upper baffle plate 53a.Dividing plate 53a, 53b are formed from a resin, can with case body 51 insulation, so terminal board 63a～63b and control substrate 64 can be directly installed on dividing plate 53a, the 53b.On the other hand, outdoor unit 1 is provided with post processing frequency lower inverse converter 61a, 61b, choke 61c and noise filter 62a, 62b (second electric parts) and then is configured among the inner space D.But, even for the converter 61a, the 61b that are configured among the inner space D, also can see through dividing plate 53a, 53b up and down between the window portion 57 that forms and see from lid member 52 1 sides and (with reference to Fig. 7) such as terminal connecting portions need not take off dividing plate 53, can do MIN processing.
In the bottom of inner space D, be noise filter 62a, the 62b that the position that is positioned at inner space D one side of bulge 56 disposes longer dimension.Promptly, configuration control substrate 64, tabular electric parts such as converter 61a, 61b in the more shallow space of the depth on case body 51 tops, and in the darker space of the depth of case body 51 bottoms (bulge 56), noise filter 62a, 62b, terminal board 63a～63b that configuration sized is long.So, just improved the space utilization of electric parts case 15.
In addition, the same with the action of the outdoor unit 1 of above-mentioned explanation when outdoor unit turns round, the air that is inhaled into housing 12 inside by behind the heat exchanger 13b when enclosure interior flows, produce towards above the streamline that flows of air blow-off outlet 22a.For example near the part that is positioned at back plate 24 1 sides of electric parts case 15, produce the air-flow (with reference to Fig. 5) as streamline F.
Here, when compressor 13a and fan 14 runnings, inverse converter 61a, 61b and choke 61c in the electric parts case 15 generate heat all the time.Yet inverse converter 61a, 61b and choke 61c are configured among the inner space D, are installed in the rear face 51b of case body 51 simultaneously, and rear face 51b is provided with fin 54,55, so these parts can access sufficient cooling.Therefore, heat is difficult to reach front space C, can protect the low control substrate 64 of hear resistance.
