The electric control box 10 includes an electric control box body and an insulation layer 20, which is provided on at least a portion of the outer surface of the electric control box body.

[0081] It should be noted that the insulation layer 20 here can be set on part of the surface of the electric control box body, or the insulation layer 20 can be set on the entire surface of the electric control box body, both of which can play the role of insulating the electric control box body and reduce the probability of heat exchange between the heat in the electric control box body and the outside world.

[0082] According to the electric control box 10 of the present application, by providing a thermal insulation layer 20 on at least part of the outer surface of the electric control box body, the probability of heat exchange between the heat inside the electric control box 10 and the outside world can be reduced, the probability of condensation occurring in the electric control box 10 can be reduced, and the anti-condensation effect of the electric control box 10 can be improved.

The shape of the insulation layer 20 is consistent with the shape of the electric control box body. For example, when the electric control box body is a rectangular box-shaped structure, the shape of the insulation layer 20 is also a rectangular box-shaped structure, and the space enclosed by the insulation layer 20 is adapted to the outer contour of the electric control box body, so that the inner surface of the insulation layer 20 can be fitted with the outer surface of the electric control box body, thereby improving the insulation effect of the electric control box 10.

[0084] Optionally, as shown in Figure 2, the electric control box body includes an end plate 15 and a side plate, the side plate is arranged around the outer edge of the end plate 15, and at least one of the end plate 15 and the side plate is provided with a through hole; the insulation layer 20 is provided with an opening corresponding to the through hole, wherein the through hole and the opening here correspond to each other one by one, which can realize the entry or outflow of airflow, and can also facilitate the wiring harness and other components to pass through the through hole and the corresponding opening from the inside of the electric control box body to the outside of the electric control box body.

[0085] The side panels are typically rectangular ring-shaped structures, and in this case, the end panels 15 are rectangular plate-shaped structures, making the electrical control box body a box-shaped structure with one end open. The side panels can also be configured as ring-shaped structures of other shapes, and the end panels 15 can also be corresponding shapes.

[0091] The air inlet 16 and the air outlet 17 here can be set as rectangular holes or through holes of other shapes. Accordingly, the shape of the first opening 21 of the insulation layer 20 is consistent with the shape of the air inlet 16, and the shape of the second opening 22 of the insulation layer 20 is consistent with the shape of the air outlet 17.

[0092] In addition, it is important to point out that the air inlet 16 is formed on the third side plate 13, thereby forming a bottom air inlet structure.

[0093] Optionally, at least one of the side panel and the end panel 15 is provided with a wire hole 18; a third opening 23 corresponding to the wire hole 18 is provided on the insulation layer 20. At this time, the wiring harness in the electrical control box 10 passes through the wire hole 18 and the third opening 23 in sequence and then extends to the outside of the electrical control box 10, which facilitates the installation of the wiring harness.

[0094] Optionally, the side panels and the end panels 15 are respectively provided with wire threading holes 18; the number of the third openings 23 is at least two, and at least two third openings 23 are respectively arranged corresponding to the wire threading holes 18.

[0095] There are also three third openings 23 , which are respectively provided corresponding to the three wire threading holes 18 , so as to facilitate the leading out of the wire harness.

[0096] It should be emphasized that the electric control box 10 in the present application can realize convenient wiring during the installation process by providing the third opening 23 and the wire threading hole 18, and the insulation layer 20 is relatively soft, which can achieve the purpose of preventing wire cutting.

[0097] Optionally, the electric control box 10 further includes an electric control box cover 30, which is detachably connected to the electric control box body to achieve sealing of the electric control box body. The shape of the electric control box cover 30 is consistent with the shape of the end plate 15, and can be a rectangular plate structure or a structure of other shapes.

[0099] Optionally, the electrical control box assembly 100 also includes a mounting member 80, an open opening 161 is provided at one end of the electrical control box body 10, and at least a portion of the circumferential edge of the end of the electrical control box body 10 where the open opening 161 is provided is provided with a flange 19, the flange 19 extends in a direction away from the open opening 161, and a mounting member 80 extends outward along the length direction of the flange 19.

[0100] It should be noted that the electric control box body 10 here is generally a rectangular box structure, and an open mouth 161 is provided at one end of the rectangular box. The open mouth 161 is usually closed to achieve sealing of the electric control box body 10. Specifically, the electric control box body 10 includes a first side panel 11, a second side panel 12, a third side panel 13 and a fourth side panel 14 connected in sequence, wherein the first side panel 11, the second side panel 12, the third side panel 13 and the fourth side panel 14 surround a rectangular cylindrical structure, one end of the rectangular cylindrical structure is the open mouth 161, and the other end of the rectangular cylindrical structure is connected to the end plate 15. The third side panel 13 is generally located at the bottom of the electric control box assembly 100 when the electric control box assembly 100 is in the installed state. Therefore, in order to facilitate the lead-out of the wiring harness, the third side panel 13 is provided with a high-voltage outlet 131 and a low-voltage outlet 132, so that the internal components of the electric control box assembly 100 can be partitioned.

[0101] Optionally, a wire hole 18 may be provided on any one of the first side plate 11 , the second side plate 12 , the fourth side plate 14 and the end plate 15 to facilitate the connection of the wire harness with components outside the electric control box assembly 100 after passing through the wire hole 18 .

Normally, the entire circumferential edge of the end of the electric control box body 10 with the open opening 161 is provided with a flange 19.

[0104] As a preferred embodiment, the mounting member 80 can also be directly connected to the outer side surface of the electric control box body 10. That is, there is no need to set the flange 19 on the electric control box body 10. The mounting member 80 can be directly connected to the outer surface of the second side panel 12 and the fourth side panel 14 of the electric control box body 10, which can also improve the strength of the electric control box assembly 100.

[0105] According to the electric control box assembly 100 of the present application, the mounting member 80 is extended outward along the length of the flange 19, thereby reinforcing the strength of at least a portion of the flange 19, thereby improving the strength of the electric control box assembly 100. Generally, after the mounting member 80 is extended outward along the length of the flange 19, the thickness of the flange 19 can be increased, and the electric control box assembly 100 can be more easily fixed.

[0106] Optionally, the mounting member 80 and the flange 19 can be an integral structure or a split structure. When the mounting member 80 and the flange 19 adopt a split structure, screws and other connecting members can be used to realize the connection between the mounting member 80 and the flange 19. Considering that the electric control box assembly 100 is usually an integrally formed structure, the mounting member 80 and the flange 19 can also be set as an integral structure, which can realize the integral forming between the electric control box body 10 and the mounting member 80, simplifying the installation process of the electric control box assembly 100 and improving the assembly efficiency of the electric control box assembly 100.

[0107] It should be noted that, in order to install the electric control box assembly 100 on the air conditioner 1000, a mounting member 80 for mounting the electric control box assembly 100 is usually provided on the housing 200 of the air conditioner 1000, and then the electric control box assembly 100 is connected to the mounting member 80. This results in a large number of installation steps for the electric control box assembly 100 and low assembly efficiency. In the present application, however, the mounting member 80 is integrated into the electric control box body 10, which simplifies the installation steps of the electric control box assembly 100, reduces the number of screws used, and improves the strength of the electric control box assembly 100, thereby reducing the chance of damage to the electric control box assembly 100.

[0108] Optionally, the electric control box cover 30 and the electric control box body 10 are detachably connected, and the mounting member 80 is provided on the surface of the flange 19 facing away from the electric control box cover 30 .

[0123] The second aspect of the present application provides an electric control box assembly 100, as shown in Figures 4 to 8, wherein Figure 4 schematically shows an overall structural diagram of the electric control box assembly 100 according to an embodiment of the present application, Figure 5 is a structural diagram of the electric control box assembly 100 shown in Figure 4 at a second viewing angle, Figure 6 is a schematic diagram of the internal structure of the electric control box assembly 100 shown in Figure 4, Figure 7 is a schematic diagram of the internal structure of the electric control box assembly 100 shown in Figure 5 at a second viewing angle, and Figure 8 is a structural diagram of the airflow direction inside the electric control box assembly 100 shown in Figure 5. The electric control box assembly 100 includes an electrical component 40 and the electric control box 10 as mentioned in the above embodiment, and the electrical component 40 is disposed in the electric control box 10.

[0124] The electrical components 40 here include multiple functional components. Specifically, the electrical components 40 include high-current components 41 and low-current components 42.

Of course, the high-voltage outlet 131 and the low-voltage outlet 132 here can also be adjusted and changed according to the positions of the high-voltage components 41 and the low-voltage components 42, such as interchanging the high-voltage outlet 131 and the low-voltage outlet 132.

[0127] Optionally, to allow the high-voltage outlet 131 and the low-voltage outlet 132 to communicate with the exterior of the electrical control box body, a fourth opening 24 is correspondingly provided on the insulation layer 20, thereby enabling both the high-voltage outlet 131 and the low-voltage outlet 132 to communicate with the exterior of the electrical control box body. The number of fourth openings 24 is at least two, which is equal to the total number of the high-voltage outlet 131 and the low-voltage outlet 132.

[0128] Optionally, the electrical control box assembly 100 also includes a circuit board 70 located inside the electrical control box body, and electrical components 40 and a heat sink 60 arranged on the circuit board 70. That is, the heat sink 60 and the electrical components 40 are both arranged on the circuit board 70. When the electrical components 40 are in working state, heat is generated, and airflow is required to discharge the heat from the electrical control box body.

[0129] As mentioned earlier, the air duct assembly 50 is formed within the electrical control box 10, and a heat dissipation duct is formed within the air duct assembly 50. The ends of the heat dissipation duct are connected to the air inlet 16 and the air outlet 17, respectively. The electrical components 40 are located within the heat dissipation duct, allowing the heat generated by the electrical components 40 to be discharged from the electrical control box body through airflow. For the electrical control box assembly 100, the airflow flows through the air inlet 16, the heat dissipation duct within the air duct assembly 50, and the air outlet 17, forming a circular flow.

[0130] The third aspect of the present application proposes an air conditioning device 1000, as shown in Figures 9 to 12, wherein Figure 9 schematically shows a structural diagram of the air conditioning device 1000 according to an embodiment of the present application, Figure 10 is a schematic diagram of the internal structure of the air conditioning device 1000 shown in Figure 9, Figure 11 is a schematic diagram of the layout structure of the fan assembly 400 and the electrical control box assembly 100 of the air conditioning device 1000 shown in Figure 9, and Figure 12 is a schematic diagram of the internal structure of the air conditioning device shown in Figure 9 (side view). The air conditioning device 1000 includes a fan assembly 400 and an electrical control box assembly 100 as mentioned in the above embodiment, the number of the fan assemblies 400 is at least two, and the at least two fan assemblies 400 are coaxial and spaced apart; the electrical control box assembly 100 is provided with an air outlet 17, and the air outlet 17 is arranged toward the fan assembly 400.

[0131] 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 .

[0132] As shown in FIG8 , the arrow direction in FIG8 indicates the flow direction of the airflow. After multiple changes in direction, 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.

[0133] 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.

[0134] It should be noted that the air outlet 17 can be provided 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 .

[0135] Optionally, the air conditioning apparatus 1000 further includes a heat exchange assembly 300, which is disposed vertically below the electrical control box assembly 100. An air outlet 17 protrudes from the electrical control box body, and the air outlet 17 is tilted toward the heat exchange assembly 300. In other words, the air outlet 17 protrudes from the end plate 15 and is tilted downward. This reduces the chance of water entering the electrical control box body through the air outlet 17 when cleaning the fan assembly 400 and / or the heat exchange assembly 300.

[0136] As shown in Figure 8, 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. The specific angle can be 80 degrees, 60 degrees or 50 degrees, etc., so that when water is cleaning the fan assembly 400 and / or the heat exchange assembly 300, the probability of water entering the electrical control box body from the air outlet 17 is reduced.

[0137] Optionally, as shown in FIG12 , the air inlet 16 of the electrical 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 16. In FIG12 , 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, where the YY direction represents the height of the air conditioner 1000. Part of the airflow from the air inlet area of ​​the heat exchange assembly 300 passes through the heat exchange assembly 300 and enters the fan assembly 400. The remaining airflow enters the interior of the electrical control box assembly 100 through the air inlet 16 and enters the fan assembly 400 after passing through the air outlet 17. The arrows in FIG12 indicate the direction of the airflow.

[0138] 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 can be an acute angle or a right angle, such as 60 degrees or 70 degrees.

[0139] The air conditioning device 1000 in the present application can quickly install the electric control box assembly 100 in the casing 200, thereby achieving efficient installation of the electric control box assembly 100.

[0140] Optionally, as shown in Figures 13 to 15, the air conditioning equipment 1000 further includes a support member 500, which is provided with a support groove 501, and at least part of the electric control box body 10 can be inserted into the support groove 501, thereby forming a support effect on the electric control box body 10 through the support groove 501.

[0141] Optionally, the support member 500 further includes a support base 502 , which is disposed at the bottom of the support member 500 to facilitate stable placement of the electric control box assembly 100 .
