[0053] like Figures 1 to 8As shown, Figure 1 The structure diagram of the air conditioning cabinet 1000 according to the embodiment of the utility model is schematically shown. Figure 2 for Figure 1 The internal structure diagram of the air conditioning cabinet 1000 is shown in FIG. Figure 4 for Figure 3 The structure diagram of the electric control box assembly 100 of the air-conditioning cabinet 1000 shown in FIG. Figure 6 for Figure 5 The cross-sectional structural diagram (part) of the air-conditioning cabinet 1000 along the AA section shown in FIG. According to the embodiment of the utility model, an air-conditioning cabinet 1000 is proposed, and the air-conditioning cabinet 1000 includes a housing 400, an electric control box assembly 100, a heat exchange assembly 300 and a fan assembly 200, wherein an installation space 402 is formed inside the housing 400; at least part of the electric control box assembly 100 is arranged in the installation space 402, and the electric control box assembly 100 is connected to the housing 400; the heat exchange assembly 300 is also arranged in the installation space 402, and the heat exchange assembly 300 is arranged below the electric control box assembly 100 in the vertical direction; the fan assembly 200 is arranged above the heat exchange assembly 300 in the vertical direction, and the fan assembly 200 is arranged on the side of the electric control box assembly 100 away from the housing 400.

[0054] The vertical direction mentioned here is Figure 6 In the YY direction, that is, the heat exchange assembly 300 is arranged below the electric control box assembly 100 along the YY direction. The fan assembly 200 mentioned here is arranged on the side of the electric control box assembly 100 away from the housing 400, which means that the fan assembly 200 is arranged on the left side of the electric control box assembly 100 along the XX direction, that is, the fan assembly 200 is farther away from the housing 400 connected to the electric control box assembly 100 relative to the electric control box assembly 100. In this embodiment, the fan assembly 200 and the electric control box assembly 100 are staggered in the horizontal direction. At this time, the fan assembly 200, the electric control box assembly 100 and the heat exchange assembly 300 are respectively arranged in independent spaces, and the influence between them is small, so that the electric control box assembly 100 is in a relatively stable working environment, reducing the influence of the fan assembly 200 and the heat exchange assembly 300 on the electric control box assembly 100.

[0055] In addition, it should be noted that the connection between the electric control box assembly 100 and the housing 400 is usually that the electric control box assembly 100 is connected to the housing 400 located on the side, so that it is convenient to install and remove the electric control box assembly 100. The housing 400 here is usually a rectangular installation space 402, wherein the top of the housing 400 is provided with an opening 401, and the opening 401 is connected to the installation space 402, so as to facilitate the airflow in the housing 400 to be discharged.

[0056] The fan assembly 200 is arranged on the side of the electrical control box assembly 100 away from the casing 400. At this time, the electrical control box assembly 100 is installed on a 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 is convenient for removing the electrical control box assembly 100 from the casing 400.

[0057] It should be noted that the fan assembly 200 and the electric control box assembly 100 can be located at the same height in the YY direction, or can be staggered in the YY direction, and the fan assembly 200 only needs to be located at a position that does not affect the electric control box assembly 100. However, considering that the electric control box assembly 100 needs to be located close to the fan assembly 200, the fan assembly 200 and the electric control box assembly 100 can be located at the same height in the YY direction in this embodiment.

[0058] According to the air-conditioning cabinet 1000 of the utility model, 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.

[0059] 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 utility model 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.

[0060] In addition, since the electric control box assembly 100 is located above the heat exchange assembly 300, and the fan assembly 200 and the electric 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 electric control box assembly 100.

[0061] Alternatively, if Figures 3 to 5 As shown, Figure 3 for Figure 2 The internal structure diagram of the electric control box assembly 100 of the air conditioning cabinet 1000 is shown in FIG. Figure 5 for Figure 2The structure diagram of the air conditioner cabinet 1000 shown in the second viewing angle. The electric control box assembly 100 includes an electric control box body 10, a circuit board 30 located in the electric control box body 10, and electrical components 40 and a heat sink 50 arranged on the circuit board 30. That is, the heat sink 50 and the electrical components 40 are both arranged on the circuit board 30. When the electrical components 40 are in working state, heat is generated, and airflow is required to discharge the heat from the electric control box body 10.

[0062] In addition, if Figure 7 As shown, Figure 7 for Figure 5 The cross-sectional structural diagram of the electric control box assembly 100 of the air conditioning cabinet 1000 is shown in FIG. The electric control box assembly 100 further includes an air duct assembly 60, in which a heat dissipation air duct 70 is formed, and an air inlet 112 and an air outlet 121 of the heat dissipation air duct 70 are respectively formed on the electric control box body 10, and at least part of the radiator 50 is disposed in the heat dissipation air duct 70.

[0063] 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 the present utility model, the air inlet 112 is a hole-shaped structure, and the air outlet 121 is a protruding structure.

[0064] Optionally, the electric 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 the side panel 11 is provided with one of the air inlet portion 112 and the air outlet portion 121, and the end panel 12 is provided with the other of the air inlet portion 112 and the air outlet portion 121; 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 bent duct.

[0065] 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 wind duct with a bent structure can be formed between the air inlet 112 and the air outlet 121, thereby realizing effective heat dissipation of the electric control box assembly 100.

[0066] 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, so as to achieve the effect of air intake from the bottom of the electric control box body 10 and air outlet from the side.

[0067] Optionally, a wire hole 13 is provided on one of the end plate 12 and the side plate 11, so that the wire harness can pass through the electric control box body 10 and then be connected with the corresponding components of the air conditioner cabinet 1000. In the present invention, both the end plate 12 and the side plate 11 are provided with a wire hole 13, so that the wire harness in the electric control box body 10 can pass through.

[0068] As a preferred embodiment, an air inlet 112 is provided on the side plate 11 located at the bottom in the vertical direction, and an air outlet 121 is provided on the end plate 12, and the air outlet 121 is arranged toward the fan assembly 200, so that a heat dissipation duct 70 with bottom air inlet and side air outlet can be formed. Since the air outlet 121 is arranged toward the fan assembly 200, and the air outlet 121 is arranged close to the fan assembly 200, when the fan assembly 200 generates a suction effect, the pressure at the location of the air outlet 121 can be reduced, and a pressure difference is formed between the air inlet 112 and the air outlet 121, so that the airflow can enter the heat dissipation duct 70 from the air inlet 112 and flow out from the air outlet 121.

[0069] Alternatively, if Figure 6 As shown, the air inlet portion 112 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. Figure 6 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 cabinet. 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 200, and the rest of the airflow enters the interior of the electric control box assembly 100 from the air inlet portion 112 and enters the fan assembly 200 after passing through the air outlet portion 121. Figure 6 The arrows in the figure indicate the direction of air flow.

[0070] 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.

[0071] It should be noted that the air outlet 121 can be disposed 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 .

[0072] Optionally, in order to realize the 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 used to connect with the housing 400. The mounting member 14 can be provided as an integrated structure with the side plate 11, so that the electric control box body 10 and the mounting member 14 can be integrated into one piece, simplifying the installation process of the electric control box assembly 100 and improving the assembly efficiency of the electric control box assembly 100.

[0073] 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, and the angle between them is 90 degrees, or other angles, such as 85 degrees or 95 degrees, etc., which are not specifically limited here.

[0074] 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 .

[0075] In order to achieve better heat dissipation of the electric 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 electric control box assembly 100.

[0076] Alternatively, if Figure 7 As shown, 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 airflow flows in the heat dissipation duct 70, the resistance formed by the bending structure is reduced, and the impact on the airflow speed is reduced.

[0077] Optionally, continue to refer to Figure 7 As shown, the air outlet 121 is protruded on the end plate 12, and the air outlet direction of the air outlet 121 is inclined downward. In other words, the air outlet 121 is protruded on the end plate 12, and the direction of the air outlet 121 is inclined downward, so that when cleaning the fan assembly 200 and / or the heat exchange assembly 300, the probability of water entering the electric control box body 10 from the air outlet 121 can be reduced.

[0078] like Figure 7 As shown, 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, and the specific angle may be 100 degrees, 120 degrees or 150 degrees, etc., thereby reducing the probability of water entering the electrical control box body 10 from the air outlet 121 when water is cleaning the fan assembly 200 and / or the heat exchange assembly 300.

[0079] The specific structure of the air duct assembly 60 will be described in detail below. The air duct assembly 60 is formed in the space inside the electric control box body 10, so that the airflow only needs to flow through the heat dissipation air duct 70 surrounded by the air duct assembly 60, reducing the influence of the heat dissipation airflow on the circuit board 30 and / or the electrical components 40.

[0080] Optionally, continue to refer to Figure 7As shown, the air duct assembly 60 includes a first plate 61 and a second plate 62 , at least one of the first plate 61 and the second plate 62 is a bent plate, and the first plate 61 and the second plate 62 surround at least a portion of the heat dissipation air duct 70 .

[0081] 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 .

[0082] Optionally, the air duct assembly 60 further includes a third plate body 63 , wherein the third plate body 63 , the second plate body 62 and the first plate body 61 together enclose at least a portion of the heat dissipation air duct 70 .

[0083] 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.

[0084] 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.

[0085] Optionally, continue to refer to Figure 7 As shown, the first plate body 61 includes a first transverse plate portion 611 and a first vertical plate portion 612 which are arranged at an angle, and the second plate body 62 includes a second transverse plate portion 621 and a second vertical plate portion 622 which are arranged at an angle, the first transverse plate portion 611 and the second transverse plate portion 621 are respectively arranged on both sides of the radiator 50 in the vertical direction, 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, 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.

[0086] 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.

[0087] 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.

[0088] Continue to refer to Figure 7As shown, 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 it can flow out from the air outlet portion 121 to take away the heat generated in the electrical control box assembly 100.

[0089] Preferably, the free end of the second vertical plate portion 622 is flush with the top of the radiator 50 or slightly lower than the top of the radiator 50 , so that most or all of the airflow can pass through the radiator 50 and then flow out from the air outlet 121 .

[0090] 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.

[0091] 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.

[0092] 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 .

[0093] 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 .

[0094] 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 arranged in a horizontal direction and the second vertical plate portion 622 is arranged in a vertical direction, so that the airflow can be easily changed in direction and the resistance of the airflow during the flow process is reduced.

[0095] 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 transverse plate portion 621 facing the end plate 12. By fitting 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 airflow can flow out from the air outlet 121.

[0096] The heat dissipation duct 70 formed by the first heat dissipation duct 71 and the second heat dissipation duct 72 in the utility model has a maze structure. After the airflow of the air-conditioning cabinet 1000 enters from the air inlet part 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.

[0097] In addition, the second plate body 62 is provided with a through hole for air flow to pass through, so that after the air flow enters from the air inlet 112, it can smoothly enter the first heat dissipation duct 71 and the second heat dissipation duct 72, and then flow out from the air outlet 121, taking away the heat in the electric control box assembly 100, thereby achieving heat dissipation of the electric control box assembly 100. Figure 7 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 121 to achieve sufficient heat dissipation for the electric control box assembly 100.

[0098] 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 bending positions of the first plate body 61 and the third plate body 63 are also smooth transition structures, which facilitates the flow of air and reduces the resistance of the flow process.

[0099] Alternatively, if Figure 8 As shown, Figure 8 for Figure 6 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 FIG.

[0100] Alternatively, if Figure 3 and Figure 4 As shown, the electric control box assembly 100 further includes a heat preservation layer 15 , which is disposed on at least a portion of the outer surface of the electric control box body 10 .

[0101] According to the electric control box assembly 100 of the utility model, by providing a thermal 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 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.

[0102] 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.

[0103] 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 , so that a heat dissipation duct 70 can be formed.

[0104] Optionally, the electric control box assembly 100 also 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 away from the end panel 12, so as to facilitate the disassembly of the electric control box assembly 100 and the replacement of the circuit board 30, the electrical components 40 or the radiator 50.

[0105] 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.

[0106] 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.

[0107] 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.

[0108] The utility model divides the strong current components and the weak current components into zones to avoid staggered arrangement of the strong current components and weak current components, and to prevent the weak current components from electromagnetic and signal interference from the strong current components, thereby improving the accuracy and reliability of the control of the electric control box assembly 100.

[0109] The air conditioning cabinet 1000 in the present invention may be a wall-mounted air conditioning device, a cabinet air conditioning device, a window air conditioning device, etc. This embodiment does not further limit the type of the air conditioning device.

[0111] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
