Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0040] It should be understood that the terms used herein are for the purpose of describing specific example embodiments only and are not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "one", "an" and "said" as used herein may also be meant to include plural forms. The terms "comprise", "include", "contain" and "have" are inclusive and therefore specify the presence of stated features, steps, operations, elements and / or parts, but do not exclude the presence or addition of one or more other features, steps, operations, elements, parts, and / or combinations thereof.

It should also be understood that additional or alternative steps may be used.

[0041] Although the terms first, second, third, etc. can be used in the text to describe multiple elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms can only be used to distinguish an element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates otherwise, terms such as "first", "second" and other numerical terms do not imply order or sequence when used in the text. Therefore, the first element, component, region, layer or section discussed below can be referred to as the second element, component, region, layer or section without departing from the teaching of the example embodiments.

[0042] For ease of description, spatially relative terms may be used herein to describe the relationship of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," and the like.

Thus, the example term "below" can encompass both above and below orientations.

[0043] As shown in Figures 1 to 8, Figure 1 schematically shows a structural diagram of an air-conditioning cabinet 1000 according to an embodiment of the present application, Figure 2 is a schematic diagram of the internal structure of the air-conditioning cabinet 1000 shown in Figure 1, Figure 4 is a structural diagram of the electrical control box assembly 100 of the air-conditioning cabinet 1000 shown in Figure 3 at a second perspective, and Figure 6 is a sectional structural diagram (partial) of the air-conditioning cabinet 1000 shown in Figure 5 along the AA section. According to an embodiment of the present application, an air-conditioning cabinet 1000 is proposed, which includes a casing 400, an electrical control box assembly 100, a heat exchange assembly 300 and a fan assembly 200, wherein an installation space 402 is formed inside the casing 400; at least part of the electrical control box assembly 100 is arranged in the installation space 402, and the electrical control box assembly 100 is connected to the casing 400; the heat exchange assembly 300 is also arranged in the installation space 402, and the heat exchange assembly 300 is arranged below the electrical control box assembly 100 in a vertical direction; the fan assembly 200 is arranged above the heat exchange assembly 300 in a vertical direction, and the fan assembly 200 is arranged on the side of the electrical control box assembly 100 facing away from the casing 400.

[0044] The vertical direction referred to herein is the YY direction in FIG6 , meaning that the heat exchange assembly 300 is disposed below the electrical control box assembly 100 along the YY direction. The fan assembly 200 disposed on the side of the electrical control box assembly 100 facing away from the housing 400 refers to the fan assembly 200 being disposed on the left side of the electrical control box assembly 100 along the XX direction. In other words, the fan assembly 200 is further away from the housing 400 connected to the electrical control box assembly 100 than the electrical control box assembly 100. In this embodiment, the fan assembly 200 and the electrical control box assembly 100 are staggered in the horizontal direction. In this case, the fan assembly 200, the electrical control box assembly 100, and the heat exchange assembly 300 are each disposed in an independent space, minimizing the impact of each other. This provides the electrical control box assembly 100 with a relatively stable operating environment, reducing the impact of the fan assembly 200 and the heat exchange assembly 300 on the electrical control box assembly 100.

[0045] In addition, it should be noted that the connection between the electric control box assembly 100 and the housing 400 is typically made by connecting the electric control box assembly 100 to the housing 400 located on the side, thereby facilitating installation and removal of the electric control box assembly 100. The housing 400 is typically surrounded by a rectangular installation space 402, wherein the top of the housing 400 is provided with an opening 401, which communicates with the installation space 402, facilitating the discharge of airflow within the housing 400.

[0046] The fan assembly 200 is arranged on the side of the electrical control box assembly 100 facing away from the casing 400. At this time, the electrical control box assembly 100 is installed on one side of the casing 400, and the fan assembly 200 is closer to the middle position of the installation space 400 along the XX direction, which makes it convenient to remove the electrical control box assembly 100 from the casing 400.

[0047] It should be noted that the fan assembly 200 and the electrical control box assembly 100 can be located at the same height in the YY direction, or they can be staggered in the YY direction. It is sufficient for the fan assembly 200 to be located at a position that does not affect the electrical control box assembly 100. However, considering that the electrical control box assembly 100 needs to be located close to the fan assembly 200, in this embodiment, the fan assembly 200 and the electrical control box assembly 100 can be located at the same height in the YY direction.

[0048] According to the air-conditioning cabinet 1000 of the present application, by locating the electric control box assembly 100 and the fan assembly 200 above the heat exchange assembly 300 in the vertical direction, and arranging the fan assembly 200 on the side of the electric control box assembly 100 away from the casing 400, when installing the electric control box assembly 100, the electric control box assembly 100 can be directly connected to the casing 400; when repairing the electric control box assembly 100, it can be disassembled from the side of the casing 400 connected to the electric control box assembly 100, and will not be affected by the heat exchange assembly 300 and the fan assembly 200, thereby reducing the difficulty of installing or repairing the electric control box assembly 100.

[0049] In addition, the air-conditioning cabinet 1000, the fan assembly 200, the electrical control box assembly 100 and the heat exchange assembly 300 in the present application are respectively arranged in independent spaces, which can facilitate the installation and disassembly of the fan assembly 200, the electrical control box assembly 100 and the heat exchange assembly 300, thereby reducing the impact on each other.

[0050] In addition, since the electrical control box assembly 100 is located above the heat exchange assembly 300, and the fan assembly 200 and the electrical control box assembly 100 are staggered in the horizontal direction, the heat exchange assembly 300 and the fan assembly 200 can be washed with water without affecting the electrical control box assembly 100.

[0051] Alternatively, as shown in Figures 3 to 5, Figure 3 is a schematic diagram of the internal structure of the electric control box assembly 100 of the air conditioning cabinet 1000 shown in Figure 2, and Figure 5 is a schematic diagram of the structure of the air conditioning cabinet 1000 shown in Figure 2 from a second perspective. The electric control box assembly 100 includes an electric control box body 10, a circuit board 30 located within the electric control box body 10, electrical components 40 and a heat sink 50 disposed on the circuit board 30. In other words, the heat sink 50 and the electrical components 40 are both disposed on the circuit board 30. When the electrical components 40 are in operation, heat is generated, and airflow is required to discharge the heat from the electric control box body 10.

[0052] In addition, as shown in Figure 7, which is a cross-sectional structural diagram of the electric control box assembly 100 of the air conditioning cabinet 1000 shown in Figure 5, the electric control box assembly 100 further includes an air duct assembly 60, in which a heat dissipation duct 70 is formed. The air inlet portion 112 and the air outlet portion 121 of the heat dissipation duct 70 are respectively formed on the electric control box body 10, and at least a portion of the radiator 50 is disposed in the heat dissipation duct 70.

[0053] The air inlet 112 may be a hole-shaped structure, that is, the air inlet 112 is a hole-shaped structure formed on the electric control box body 10, and the air outlet 121 may be a hole-shaped structure or a protruding structure with a through hole formed in the protruding structure. In this application, the air inlet 112 is a hole-shaped structure, and the air outlet 121 is a protruding structure.

[0054] Optionally, the electrical control box body 10 includes a side panel 11 and an end panel 12, wherein the side panel 11 is arranged around the outer edge of the end panel 12, and one of the air inlet portion 112 and the air outlet portion 121 is provided on the side panel 11, and the other of the air inlet portion 112 and the air outlet portion 121 is provided on the end panel 12; the air inlet portion 112 and the air outlet portion 121 respectively constitute the two ends of the heat dissipation duct 70, and the heat dissipation duct 70 here is usually a curved duct.

[0055] The side panel 11 here is a rectangular ring structure, and the end panel 12 here is a rectangular plate structure. The end panel 12 and the side panel 11 form a rectangular box structure with an open end, wherein one of the air inlet 112 and the air outlet 121 is arranged on the side panel 11, and the other of the air inlet 112 and the air outlet 121 is arranged on the end panel 12, so that a bent air duct can be formed between the air inlet 112 and the air outlet 121, thereby achieving effective heat dissipation of the electrical control box assembly 100.

[0056] Specifically, the air inlet 112 is arranged on the side plate 11, and the air outlet 121 is arranged on the end plate 12, wherein the air inlet 112 is located at the bottom of the electric control box body 10, which can achieve the effect of air intake from the bottom of the electric control box body 10 and air outlet from the side.

[0057] Optionally, a wire hole 13 is provided on one of the end plate 12 and the side plate 11 to facilitate the wiring harness to pass through the electric control box body 10 and connect with the corresponding components of the air conditioning cabinet 1000. In this application, both the end plate 12 and the side plate 11 are provided with a wire hole 13 to facilitate the wiring harness in the electric control box body 10 to pass through.

[0058] As a preferred embodiment, an air inlet 112 is provided on the side panel 11 located at the bottom in the vertical direction, and an air outlet 121 is provided on the end panel 12, and the air outlet 121 is disposed toward the fan assembly 200, thereby forming a heat dissipation duct 70 with bottom air intake and side air outlet. Because the air outlet 121 is disposed toward the fan assembly 200 and is disposed close to the fan assembly 200, when the fan assembly 200 generates an air suction effect, the pressure at the location of the air outlet 121 can be reduced, forming a pressure difference between the air inlet 112 and the air outlet 121, thereby facilitating airflow from the air inlet 112 into the heat dissipation duct 70 and out through the air outlet 121.

[0059] Optionally, as shown in FIG6 , the air inlet 112 of the electrical control box assembly 100 is positioned 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 FIG6 , 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 cabinet. 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 200 . The remaining airflow enters the interior of the electrical control box assembly 100 through the air inlet 112 and enters the fan assembly 200 after passing through the air outlet 121 . The arrows in FIG6 indicate the direction of the airflow.

[0060] 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.

[0061] It should be noted that the air outlet portion 121 can be provided at the lower portion of the end plate 12 , so as to form at least two continuous bending structures in the electric control box body 10 .

[0062] Optionally, to facilitate installation of the electric control box assembly 100, a mounting member 14 is provided on the electric control box body 10, wherein the mounting member 14 is configured to connect to the housing 400. The mounting member 14 can be integrally formed with the side panel 11, thereby achieving an integrated structure between the electric control box body 10 and the mounting member 14, simplifying the installation process of the electric control box assembly 100 and improving the assembly efficiency of the electric control box assembly 100.

[0063] Optionally, the mounting member 14 includes a first plate portion and a second plate portion, and the first plate portion and the second plate portion are interconnected and intersectingly arranged. Here, the first plate portion and the second plate portion can be arranged perpendicular to each other, with an angle of 90 degrees between them, or other angles, such as 85 degrees or 95 degrees, etc., which are not specifically limited here.

[0064] Here, the mounting member 14 is configured as a structure of a first plate portion and a second plate portion connected to each other, which can enhance the aesthetics of the electric control box assembly 100 and also increase the strength of the electric control box assembly 100 .

[0065] In order to achieve better heat dissipation of the electronic control box assembly 100, the bent air duct here includes at least two continuous bent structures, so that the heat dissipation air duct 70 can form a maze-like heat dissipation structure, increase the total length of the heat dissipation air duct 70 in the air duct assembly 60, and achieve effective heat dissipation of the electronic control box assembly 100.

[0066] Optionally, as shown in Figure 7, at least part of the bending structure is a smooth structure, that is, the end angle position of the bending structure is a smooth structure, such as an arc-shaped end angle, etc. Through this structural setting, when the air flow flows in the heat dissipation duct 70, the resistance formed by the bending structure is reduced, and the impact on the air flow speed is reduced.

[0067] Alternatively, as shown in FIG. 7 , the air outlet 121 protrudes from the end plate 12, and the air outlet 121 is arranged to discharge air in an obliquely downward direction. In other words, the air outlet 121 protrudes from the end plate 12, and the air outlet 121 is arranged to discharge air in an obliquely downward direction. This can reduce the chance of water entering the electrical control box body 10 through the air outlet 121 when cleaning the fan assembly 200 and / or the heat exchange assembly 300.

[0068] As shown in Figure 7, the angle between the air flow direction of the air outlet 121 and the outer surface of the end plate 12 is α, where α is a right angle or an obtuse angle. The specific angle can be 100 degrees, 120 degrees or 150 degrees, etc., so that when water is cleaning the fan assembly 200 and / or the heat exchange assembly 300, the probability of water entering the electrical control box body 10 from the air outlet 121 is reduced.

[0069] The following describes the specific structure of the air duct assembly 60. The air duct assembly 60 is formed within the space within the electrical control box body 10, so that airflow only needs to flow through the heat dissipation duct 70 surrounded by the air duct assembly 60, thereby reducing the impact of the heat dissipation airflow on the circuit board 30 and / or electrical components 40.

[0070] Optionally, continuing to refer to FIG. 7 , the air duct assembly 60 includes a first plate 61 and a second plate 62 , at least one of which is a bent plate, and the first plate 61 and the second plate 62 enclose at least a portion of the heat dissipation duct 70 .

[0071] The bent plate mentioned here refers to a plate-like structure with a bent structure, so that at least a portion of the heat dissipation duct 70 can be formed between the first plate body 61 and the second plate body 62 .

[0072] Optionally, the air duct assembly 60 further includes a third plate 63 , wherein the third plate 63 , the second plate 62 and the first plate 61 together enclose at least a portion of the heat dissipation air duct 70 .

[0073] Optionally, the circuit board 30 is located outside the heat dissipation duct 70. Even if water enters the heat dissipation duct 70 from the air inlet 112, it will not affect the circuit board 30, thereby protecting the circuit board 30 and achieving a heat dissipation effect for the circuit board 30.

[0074] The structures of the first plate body 61 , the second plate body 62 and the third plate body 63 will be described in detail below.

[0075] Optionally, continuing to refer to Figure 7, the first plate body 61 includes a first horizontal plate portion 611 and a first vertical plate portion 612 set at an angle, and the second plate body 62 includes a second horizontal plate portion 621 and a second vertical plate portion 622 set at an angle, the first horizontal plate portion 611 and the second horizontal plate portion 621 are respectively arranged on both sides of the radiator 50 in the vertical direction, and the second vertical plate portion 622 is arranged between the radiator 50 and the first vertical plate portion 612, a first heat dissipation duct 71 is formed between the first vertical plate portion 612 and the second vertical plate portion 622, and a second heat dissipation duct 72 is formed between the second vertical plate portion 622 and the radiator 50, and the air inlet portion 112, the first heat dissipation duct 71, the second heat dissipation duct 72 and the air outlet portion 121 are connected in sequence.

[0076] That is, the heat dissipation duct 70 includes a first heat dissipation duct 71 and a second heat dissipation duct 72, and the first heat dissipation duct 71 and the second heat dissipation duct 72 are interconnected, and the air inlet 112, the first heat dissipation duct 71, the second heat dissipation duct 72 and the air outlet 121 are in a state of interconnection.

[0077] At least one of the first heat dissipating air duct 71 and the second heat dissipating air duct 72 has a bending structure, so that the heat dissipating air duct 70 formed by the first heat dissipating air duct 71 and the second heat dissipating air duct 72 can be a bent air duct.

[0078] Continuing with FIG7 , the free end of the second vertical plate portion 622 is higher than the bottom of the radiator 50 , that is, the top of the second vertical plate portion 622 is higher than the bottom of the radiator 50 , so that at least part of the airflow must pass through the radiator 50 before flowing out of the air outlet portion 121 to carry away the heat generated in the electrical control box assembly 100 .

[0079] Preferably, the free end of the second vertical plate portion 622 is arranged flush with the top of the radiator 50 or the free end of the second vertical plate portion 622 is slightly lower than the top of the radiator 50, so that most of the airflow or all of the airflow can pass through the radiator 50 and then flow out of the air outlet portion 121.

[0080] Optionally, the first plate body 61 also includes a first connecting plate 613 and a second connecting plate 614, wherein the first connecting plate 613 is connected to the first vertical plate portion 612, one end of the second connecting plate 614 is connected to the first horizontal plate portion 611, and the other end of the second connecting plate 614 is connected to the side panel 11, so that the first plate body 61 can form a relatively closed air duct space with the side panel 11 and the third plate body 63 of the air duct assembly 60.

[0081] The third plate body 63 here is a semi-I-shaped structure, including a third horizontal plate portion 631, a third vertical plate portion 632 and a fourth horizontal plate portion 633 connected in sequence, wherein the third horizontal plate portion 631 is connected to the first connecting plate 613 of the second plate body 62. Of course, the third plate body 63 and the first plate body 61 here can also be set as an integral structure to form an integral structure.

[0082] The inner surface of the fourth horizontal plate portion 633 is arranged to fit the radiator 50 , wherein the third vertical plate portion 632 can change the direction of the airflow so that the airflow flows out after passing through the radiator 50 , thereby achieving heat dissipation for the radiator 50 .

[0083] In order to achieve a seal between the fourth transverse plate portion 633 and the circuit board 30, a flange can be provided on the fourth transverse plate portion 633, which contacts the circuit board 30 through the flange, thereby reducing the airflow passing through the circuit board 30, so that most or all of the airflow can flow out after passing through the radiator 50.

[0084] Optionally, the second transverse plate portion 621 and the second vertical plate portion 622 of the second plate body 62 are also smoothly connected, wherein the second transverse plate portion 621 is set in the horizontal direction and the second vertical plate portion 622 is set in the vertical direction, so that the airflow can be easily changed in direction and the resistance of the airflow during the flow process is reduced.

[0085] In addition, in order to facilitate the sealing between the second plate body 62 and the end plate 12, a flange can be provided at one end of the second horizontal plate portion 621 facing the end plate 12. By attaching the flange to the inner surface of the end plate 12, the sealing between the end plate 12 and the second plate body 62 is achieved, so that the air flow can flow out from the air outlet 121.

[0086] The heat dissipation duct 70 formed by the first heat dissipation duct 71 and the second heat dissipation duct 72 in the present application has a maze structure. After the airflow of the air-conditioning cabinet 1000 enters from the air inlet 112, the heat dissipation airflow can only pass through the radiator 50 and does not need to pass through the circuit board 30, thereby achieving effective heat dissipation of the electric control box assembly 100 and protecting the circuit board 30.

[0087] In addition, the second plate 62 is provided with through holes for airflow. This allows airflow to enter the air inlet 112, smoothly enter the first heat dissipation duct 71 and the second heat dissipation duct 72, and then flow out of the air outlet 121, removing heat from the electrical control box assembly 100 and dissipating heat from the electrical control box assembly 100. The arrows in FIG7 indicate the direction of airflow. After multiple changes in direction, the airflow flows out of the air outlet 121, effectively dissipating heat from the electrical control box assembly 100.

[0088] The angle between the second horizontal plate portion 621 and the second vertical plate portion 622 can be about 90 degrees, such as 85 degrees or 95 degrees, for easy processing. Accordingly, the bends of the first plate body 61 and the third plate body 63 are also smoothly transitioned, facilitating the flow of air and reducing resistance during the flow process.

[0089] Optionally, as shown in FIG8 , FIG8 is a schematic diagram of the position structure between the fan assembly 200 and the electric control box assembly 100 of the air-conditioning cabinet 1000 shown in FIG6 .

[0090] Optionally, as shown in FIG. 3 and FIG. 4 , the electric control box assembly 100 further includes a heat-insulating layer 15 , which is disposed on at least a portion of the outer surface of the electric control box body 10 .

[0091] According to the electric control box assembly 100 of the application, by providing an insulation layer 15 on at least part of the outer surface of the electric control box body 10, the probability of heat exchange between the heat in the electric control box assembly 100 and the outside world can be reduced, the probability of condensation occurring in the electric control box assembly 100 can be reduced, and the anti-condensation effect of the electric control box assembly 100 can be improved.

[0092] Optionally, the insulation layer 15 can be an integrated structure and wrapped around the outer surface of the electric control box body 10. The structure of the insulation layer 15 is consistent with that of the electric control box body 10 and can be directly wrapped around the outer surface of the electric control box body 10. Specifically, the insulation layer 15 can be bonded to the outer surface of the electric control box body 10.

[0093] Optionally, the heat-insulating layer 15 is provided with a avoidance opening 151 for avoiding the air inlet portion 112 and a avoidance opening 151 for avoiding the air outlet portion 121 , thereby forming a heat dissipation duct 70 .

[0094] Optionally, the electric control box assembly 100 further includes an electric control box cover 20, wherein the electric control box cover 20 is detachably connected to the end of the side panel 11 facing away from the end panel 12, thereby facilitating the disassembly of the electric control box assembly 100 and the replacement of the circuit board 30, electrical components 40 or the radiator 50.

[0095] It should be noted that the electrical components 40 here include high-current components and low-current components, and the high-current components and low-current components are respectively arranged in different areas within the electric control box body 10; that is, the high-current components are concentrated in the electric control box body 10, and the low-current components are concentrated in the electric control box body 10, and are respectively located in different areas of the electric control box body 10.

[0096] Correspondingly, a high-voltage outlet and a low-voltage outlet are provided on the side panel 11 of the electric control box body 10, and the high-voltage outlet is arranged close to the high-voltage components, and the low-voltage outlet is arranged close to the low-voltage components, so that the electrical components 40 can be partitioned in the electric control box body 10, which is convenient for maintenance and replacement.

[0097] It should be noted that strong current and weak current are relative. Generally speaking, the working current of strong current electronic devices in strong current components is greater than the working current of weak current electronic devices in weak current components, that is, the power of strong current electronic devices in strong current components is greater than the power of electronic devices in weak current components.

[0098] In this application, the structure of partitioning the high-current components and the low-current components is used to avoid the staggered arrangement of the high-current components and the low-current components, and to prevent the low-current components from being interfered with by the electromagnetic and signal interference of the high-current components, thereby improving the accuracy and reliability of the control of the electric control box assembly 100.

[0099] The air-conditioning cabinet 1000 in the present application may be a wall-mounted air-conditioning device, a cabinet-type air-conditioning device, a window-type air-conditioning device, etc. This embodiment does not further limit the type of the air-conditioning device.
