Here, the outdoor side intake duct 400 refers to a portion between the front partition 300 and the rear partition 4. The outdoor side outlet duct 500 refers to a portion of the rear partition 4 on a side away from the front partition 300.

The outdoor side air supply part comprises an axial flow fan blade 5 and a motor, an output shaft of the motor is connected with the axial flow fan blade 5 to drive the axial flow fan blade 5 to rotate, and the axial flow fan blade 5 is usually positioned between the rear partition plate 4 and the outdoor heat exchanger 3.

When the air conditioner operates in a refrigerating mode, the radiator 2 is located on the air inlet side of the outdoor heat exchanger 3, and compared with the air outlet side of the outdoor heat exchanger 3, the radiating environment temperature is low, and the radiating effect can be further improved.

When in heating operation, because the radiator 2 is positioned in a low-temperature environment outside the room, the surface temperature rise of the components in the electrical box 1 is not high, and the components of the controller cannot be damaged.

As an alternative embodiment, referring to fig. 1, fig. 2 and fig. 4, the electrical box 1 is fixed on the outer wall of the outdoor side air outlet duct 500, the heat sink 2 extends into the outdoor side air outlet duct 500 through the side wall of the outdoor side air outlet duct 500, and at least part of the heat sink 2 is located on the air outlet side of the outdoor side air supply component (axial flow fan blade 5).

The electrical box 1 of this embodiment is fixed on the outer wall of the outdoor side air outlet duct 500, and can prevent the condensate water thrown away by the outdoor side air supply component (axial flow fan blade 5) from splashing onto the electrical box 1, and prevent the damage to the components inside the electrical box 1. And the heat radiator 2 for radiating the electrical box 1 penetrates through the side wall of the outdoor side air outlet duct 500 to extend into the outdoor side air outlet duct 500, can be positioned at the air outlet side of the outdoor side air supply component (axial flow fan blade 5), and can radiate heat in an active air suction mode to form forced convection around the heat radiator 2 so as to further enhance the heat radiation.

As an optional implementation manner, referring to fig. 1, 2, and 4, the outdoor side air outlet duct 500 of this embodiment is formed by surrounding the rear partition plate 4 and the outdoor heat exchanger 3, the electrical box 1 is fixed to a side of the rear partition plate 4 facing away from the outdoor side air supply component (the axial flow fan blade 5), and the heat sink 2 passes through the rear partition plate 4 and extends to a position between the rear partition plate 4 and the outdoor heat exchanger 3.

The electric appliance box 1 is fixed on one side of the rear partition plate 4, which deviates from the outdoor side air supply part (the axial flow fan blade 5), and can prevent condensed water thrown away by the outdoor side air supply part (the axial flow fan blade 5) from splashing on the electric appliance box 1 to damage components inside the electric appliance box 1, and meanwhile, the radiator 2 fixed on the electric appliance box 1 conveniently penetrates through the rear partition plate 4 to stretch into the space between the rear partition plate 4 and the outdoor heat exchanger 3, so that the structure is compact, and the installation is convenient.

As an alternative embodiment, as shown in fig. 2 and 3, in the present embodiment, the rear partition plate 4 is provided with a mounting through hole 401 through which the heat sink 2 passes.

When the electrical box 1 is fixed on the side of the rear partition plate 4 away from the outdoor side air supply component (axial flow fan blade 5), the radiator 2 fixed on the electrical box 1 passes through the installation through hole 401 and extends to a position between the rear partition plate 4 and the outdoor heat exchanger 3. Above-mentioned mounting structure, both make things convenient for electrical apparatus box 1 to be located outside outdoor side air-out wind channel 500, make things convenient for radiator 2 to pass back baffle 4 again and stretch into to outdoor side air-out wind channel 500 in, dispel the heat through the mode that initiatively induced drafts.

As an alternative embodiment, as shown in fig. 2 and 3, the shape of the mounting through hole 401 is adapted to the outer contour shape of the heat sink 2, so that the outer wall of the heat sink 2 is attached to the inner wall of the mounting through hole 401 after the heat sink 2 is mounted in place in the mounting through hole 401.

For example, if the heat sink 2 is rectangular, the mounting through-hole 401 is rectangular, and the size of the mounting through-hole 401 is just enough to allow the heat sink 2 to pass through. Therefore, the damage of components in the electric appliance box 1 caused by the fact that water thrown out by the outdoor side air supply part splashes onto the electric appliance box 1 can be prevented.

When the window type air conditioner is used for refrigerating, the air conditioner is usually required to be installed to be inclined downwards from the indoor side to the outdoor side, so that condensed water generated by an indoor side evaporator naturally flows to the rear part of the outdoor side chassis 7 and is collected at the rear part of the chassis 7. Therefore, during cooling operation, condensed water formed by the indoor-side heat exchanger is generally collected in the base pan 7 on the outdoor side.

In order to further improve the heat dissipation effect of the heat sink 2, referring to fig. 1, 2, and 4, the outdoor side air supply component of this embodiment includes the axial flow fan blade 5, the heat sink 2 is located beside the axial flow fan blade 5, and the installation position of the heat sink 2 enables water thrown up by the axial flow fan blade 5 to directly splash onto the heat sink 2, or throw water onto the rear cover plate 6 above the axial flow fan blade 5 and drip onto the heat sink 2.

During refrigeration operation, the condensed water collected in the chassis 7 is thrown out by the axial flow fan blades 5 and can be directly splashed onto the radiator 2, or the water is thrown onto the rear cover plate 6, and the water dripped from the rear cover plate 6 can drip onto the radiator 2 to form water-cooling heat dissipation.

Relatively pure air-cooled radiating mode, radiator 2 in this embodiment can utilize the mode that air-cooled heat dissipation and water-cooling heat dissipation combined together, promotes the radiating effect greatly. Meanwhile, because the radiator 2 is positioned in the outdoor air outlet duct 500 and is positioned beside the axial flow fan blade 5, forced convection can be formed around the radiator 2 by air outlet, so that heat dissipation is further enhanced, temperature rise of components in the electrical box 1 is effectively reduced, the components in the electrical box 1 are protected from being damaged, and normal and stable operation of the whole machine is ensured.

As an alternative embodiment, referring to fig. 1, 2 and 4, the heat sink 2 is disposed obliquely toward the outdoor side air blowing member (axial flow fan blade 5). The radiator 2 is arranged towards the axial flow fan blade 5, so that the effect of forced convection can be further improved, and the heat dissipation effect is improved. And the radiator 2 is obliquely arranged, so that the width size of the window type air conditioner can be reduced, and the structure is more compact.

In order to facilitate the radiator 2 to be disposed in an inclined manner toward the outdoor side air supply component (axial flow fan blade 5), specifically, as shown in fig. 2, the rear partition plate 4 located inside the outdoor side in the present embodiment includes: the air conditioner comprises a horizontal plate body 41 used for fixing an outdoor side air supply component (axial flow fan blade 5) and an inclined plate body 42 used for fixing the electric appliance box 1, wherein one side of the inclined plate body 42 is connected with the horizontal plate body 41, and one side of the inclined plate body 42, which deviates from the horizontal plate body 41, extends towards the direction close to the outdoor heat exchanger 3, so that the radiator 2 is obliquely arranged towards the outdoor side air supply component (axial flow fan blade 5) after being assembled in place on the inclined plate body 42.

The electrical apparatus box 1 is fixed in the one side that deviates from axial fan 5 of inclined plate body 42, like this, when radiator 2 passed the installation opening and extends to in outdoor side air outlet duct 500, radiator 2 can set up towards the slope of the axial fan 5 of outdoor side to further improve the effect of forcing the convection current, improve the radiating effect, make the structure compacter simultaneously.

The radiator mounting structure of this embodiment, when the outdoor ambient temperature is higher the refrigeration operation, the complete machine load increases, and radiator 2 ambient air temperature is higher. Radiator 2 in this embodiment is located outdoor side air outlet duct 500, through the mode that wind heat dissipation combines the water-cooling heat dissipation, effectively promotes the radiating effect for the complete machine can be normal operating under higher frequency, guarantees the refrigeration travelling comfort.

On the other hand, even if the chassis 7 is not filled with water, the heat radiator 2 can also radiate heat in an active air suction mode, and forced convection is formed around the heat radiator 2, so that the heat radiation efficiency of the electric box 1 is greatly improved compared with a passive western wind heat radiation mode; the radiator 2 is located the air inlet side of outdoor heat exchanger 3, compares in the air-out side of outdoor heat exchanger 3, and scattered ambient temperature is low, can further promote the radiating effect.
