Figure 5 for Figure 4 The schematic diagram of the structure of the electric control box assembly 100 in the second viewing angle is shown in FIG. Figure 6 for Figure 4The internal structure diagram of the electric control box assembly 100 is shown in FIG. Figure 7 for Figure 5 The internal structure diagram of the electric control box assembly 100 shown in FIG.

[0081] The electrical components 40 here include multiple functional components. Specifically, the electrical components 40 include high-current components 41 and low-current components 42. The high-current components 41 and low-current components 42 are respectively arranged in different areas in the electrical control box; that is, the high-current components 41 are centrally placed in the electrical control box, and the low-current components 42 are centrally placed in the electrical control box, and are respectively located in different areas.

[0082] Correspondingly, a high-voltage outlet 131 and a low-voltage outlet 132 are provided on the side panel of the electrical control box body, and the high-voltage outlet 131 is arranged close to the high-voltage component 41, and the low-voltage outlet 132 is arranged close to the low-voltage component 42, so that the electrical components 40 can be partitioned in the electrical control box for easy maintenance and replacement.

[0083] Specifically, as shown in the previous embodiments, a high-voltage outlet 131 is arranged in the left area of ​​the third side panel 13 of the electric control box body, and a low-voltage outlet 132 is arranged in the right area of ​​the third side panel 13.

[0086] The third aspect of the present utility model provides an air conditioning device 1000, such as Figures 9 to 12 As shown, Fig. 9 The structure diagram of the air conditioning device 1000 according to the embodiment of the utility model is schematically shown. Fig.10 for Fig. 9 The internal structure diagram of the air conditioning device 1000 is shown in FIG. Fig.11 for Fig. 9 The schematic diagram of the layout structure of the fan assembly 400 and the electric control box assembly 100 of the air conditioning device 1000 is shown in FIG. Fig.12 for Fig. 9 The internal structure diagram (side view) of the air conditioner is shown in FIG. The air conditioner 1000 includes a fan assembly 400 and an electric control box assembly 100 as mentioned in the above embodiment. The number of the fan assemblies 400 is at least two, and at least two fan assemblies 400 are coaxial and spaced apart. The electric control box assembly 100 is provided with an air outlet 17, and the air outlet 17 is arranged toward the fan assembly 400.

[0087] The air conditioning device 1000 further includes a casing 200 , and the fan assembly 400 and the electric control box assembly 100 are both arranged in an installation space surrounded by the casing 200 .

[0088] like Figure 8 As shown, Figure 8 The arrow direction in the figure indicates the flow direction of the airflow. After changing direction for many times, the airflow flows out from the air outlet 17 to achieve sufficient heat dissipation of the electric control box assembly 100. The air duct through which the airflow flows is a curved air duct.

[0089] Optionally, the air outlet 17 is arranged toward the fan assembly 400, and the air outlet 17 is arranged close to the fan assembly 400. When the fan assembly 400 generates a suction effect, the pressure at the position where the air outlet 17 is located can be reduced, and a pressure difference is formed between the air inlet 16 and the air outlet 17, which facilitates the airflow to enter the heat dissipation duct from the air inlet 16 and flow out from the air outlet 17.

[0090] It should be noted that the air outlet 17 can be disposed at the lower portion of the end plate 15 , so as to form at least two continuous curved air ducts in the electric control box 10 .

[0091] Optionally, the air conditioning device 1000 further includes a heat exchange assembly 300, which is disposed below the electric control box assembly 100 in the vertical direction; the air outlet 17 is protrudingly disposed on the electric control box body, and the air outlet direction of the air outlet 17 is inclined toward the direction where the heat exchange assembly 300 is located. In other words, the air outlet 17 is protrudingly disposed on the end plate 15, and the direction of the air outlet 17 is inclined downward, so that when the fan assembly 400 and / or the heat exchange assembly 300 are cleaned, the probability of water entering the electric control box body from the air outlet 17 is reduced.

[0092] like Figure 8As shown, the angle between the air flow direction of the air outlet 17 and the outer surface of the third side panel 13 is α, where α is a right angle or an acute angle, and the specific angle may be 80 degrees, 60 degrees or 50 degrees, etc., thereby reducing the probability of water entering the electrical control box body from the air outlet 17 when water is cleaning the fan assembly 400 and / or the heat exchange assembly 300.

[0093] Alternatively, if Fig.12 As shown, the air inlet portion 16 of the electric control box assembly 100 is disposed above the heat exchange assembly 300, wherein the air inlet area of ​​the heat exchange assembly 300 is in communication with the air inlet portion 16. Fig.12 In the figure, the air inlet area of ​​the heat exchange assembly 300 is located on the right side of the heat exchange assembly 300, that is, on the right side of the heat exchange assembly 300 along the XX direction, wherein the YY direction is the height direction of the air conditioner 1000. Part of the airflow in the air inlet area of ​​the heat exchange assembly 300 passes through the heat exchange assembly 300 and enters the fan assembly 400, and the rest of the airflow enters the interior of the electric control box assembly 100 from the air inlet portion 16 and enters the fan assembly 400 after passing through the air outlet portion 17. Fig.12 The arrows in the figure indicate the direction of air flow.

[0094] It should be noted that the heat exchange assembly 300 is tilted, and the angle between the heat exchange assembly 300 and the horizontal plane may be an acute angle or a right angle, such as 60 degrees or 70 degrees.
