Embodiment approach 1

[0028] figure 1 It is a cross-sectional view of the electrical module part in the embodiment of the present invention.

[0029] The main body 1 of the electrical module part forms a case 5 through the side plate part 2 , the bottom plate part 3 and the top plate part 4 , and a plurality of circuit components for driving the compressor are housed inside the case 5 . Among the circuit components, a converter circuit section for converting AC commercial power to DC, an inverter circuit section for converting DC to AC, and a control circuit section are roughly divided and housed in respective blocks. The side plate part 2, the top plate part 4 or the bottom plate part 3 of the housing 5 are made of materials with high thermal conductivity such as metal materials, and have a waterproof and drip-proof airtight structure. In the inverter circuit section are provided diodes 6 and circuit components 7 such as capacitors and inductors, and in the inverter circuit section are provided ...

Embodiment approach 2

[0040] Figure 4 It is a schematic diagram of the outdoor unit of the air conditioner in Embodiment 2 of this invention. Figure 4 (a) is the plan view of the outdoor unit, Figure 4 (b) is its front view. In Embodiment 2, the electrical module unit main body 1 is arranged in the dead zone of the air passage formed by the outdoor blower 33 in the outdoor unit main body 30 , that is, in an area where wind does not flow or where it is difficult to flow.

[0041] exist Figure 4 Among them, the main body 1 of the electrical module part is arranged on the outer peripheral part of the bell mouth 42 which is formed on the front panel 37 of the exterior part 31 and serves as a blower guide. Although the outer peripheral portion of the bell mouth 42 serves as an air passage, an area where the wind hardly flows or the wind speed is very slow, a wasteful space is formed in the middle of the outdoor unit main body 30 . According to the present embodiment, the outdoor unit main body 3...

[0045] Image 6 is a schematic diagram of the outdoor unit of the air conditioner in Embodiment 3 of the present invention, Image 6 (a) is the plan view of the outdoor unit, Image 6 (b) is its front view.

[0046] like Image 6 As shown, the main body 1 of the electrical module part is installed on the side plate 36 of the exterior part 31 of the outdoor unit main body 30 forming the upper part of the compressor 34, and the power terminal part 47 of the main body 1 of the electrical module part faces the main body 30 of the outdoor unit. set externally. Therefore, the side plate 36 having a very large heat dissipation area can be used as a heat dissipation plate for the heat-generating circuit components in the electrical module unit main body 1 . In addition, it is installed in the vicinity of the compressor 34, and the wiring connection with the compressor 34 becomes easy. At the same time, the power supply terminal 47 provided on the main body 1 of the electrical modu...

Abstract

To realize an outdoor unit for air conditioner enhanced in reliability of an inverter driving circuit part while improving the air conditioning performance with a small size. This outdoor unit comprises an outdoor unit body 30, an outdoor heat exchanger 32, an outdoor blower 33, a compressor 34 for compressing a refrigerant, and an electric module part body 1 having a circuit part arranged in a sealed casing, the circuit part comprising at least a converter circuit part for driving a motor part, an inverter circuit part, and a control circuit part. The electric module part body 1 is arranged on the bottom plate 35 of the outdoor unit body 30.

Description

technical field [0001] The present invention relates to an air conditioner, especially an outdoor unit of a separate type air conditioner. Background technique [0002] In recent years, compressors controlled by inverters have become mainstream as compressors for household air conditioners. The compressor and the control device for controlling the compressor are mounted on the outdoor unit that constitutes the air conditioner, and the refrigeration cycle operation is performed. . [0003] Figure 7 It is a perspective view of a rough structure of an outdoor unit in a conventional split-type air conditioner. like Figure 7 As shown, the main body of the outdoor unit 100 is composed of a compressor 110 containing at least a compression mechanism part and a motor part driving the compression mechanism part in an airtight container, an outdoor heat exchanger 120 for exchanging heat with outdoor air, and an outdoor heat exchanger 120 for transferring heat exchange. A blower 130...
