There are many electrical control components inside the electrical box, such as drive components, main control components, reactors, etc. In the past, the electrical control components were usually installed on the mounting plate, and then fixed in the middle area inside the electrical box through the mounting plate. However, when installing or removing the electrical control components, the staff had to go deep into the electrical box to fix or loosen the screws, which was extremely inconvenient for installation and maintenance; moreover, the fluorine cold plate corresponding to the drive component for heat dissipation must also be set in the electrical box, resulting in the inability to apply silicone grease on the back of the fluorine cold plate, which greatly reduced the heat dissipation effect; in addition, during disassembly and assembly, in order to prevent the mounting plate and the electrical control components fixed thereon from falling and causing damage to themselves or other components, the mounting plate must be supported while the screws are fixed or loosened, which brings great inconvenience to disassembly and assembly.

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] In the description of the present invention, it should be noted that the terms "vertical direction", "upper", "lower", "horizontal" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0044] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, a mechanical connection, an electrical connection, a direct connection, or a connection through an intermediate medium, or the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] At present, the electric control components in the electrical box are arranged inside the electrical box body, which makes the installation and maintenance of the electric control components extremely inconvenient, and the back of the fluorine cold plate corresponding to the driving component cannot be coated with silicone grease. After analysis, it is found that when the electric control components are arranged inside the electrical box, the mounting plate for installing the electric control components is often fixed with screws from the side of the mounting plate facing the inside of the electrical box. When repairing, it is also necessary to remove it from the inside. Due to the obstruction of the electric control components, both the fixing and removal of the screws are extremely inconvenient, and it is easy to cause damage to the electric control components; at the same time, when the fluorine cold plate is installed on the side of the mounting plate away from the driving component, it is difficult to add a heat conductive layer between the mounting plate and the fluorine cold plate, which greatly reduces the heat dissipation efficiency. In addition, the installation of the electric control components has not been reasonably designed, so that when installing or removing, it is necessary to provide a support force for the mounting plate and the electric control components arranged thereon to prevent them from falling and causing damage to themselves and other components. This undoubtedly brings great inconvenience to installation and maintenance.

[0046] Based on this, the utility model provides an electrical box installation structure, in which the electronic control component is installed on the installation component, and then the installation component is fixed to the side panel of the box body, so that the installation component can be operated from the outside of the box body during disassembly and assembly, and a heat dissipation component for dissipating the driving components is conveniently arranged; at the same time, a supporting member is arranged on the side of the side panel facing the inside of the box body, and the installation component and the electronic control component are supported by the supporting member. During disassembly and assembly, there is no need for manual lifting to avoid damage to the components caused by the falling of the installation component and the electronic control component, which facilitates the disassembly and assembly of the electronic control component inside the electrical box and improves the installation and maintenance efficiency.

[0047] Please also see Figures 1 to 3 The electrical box installation structure provided by the utility model comprises a box body 10, a mounting assembly 20 and an electric control assembly 30. The mounting assembly 20 and the electric control assembly 30 are both arranged in the box body 10.

[0048] Specifically, the box body 10 is surrounded by a side panel 11 and a bottom cover, and a receiving cavity is formed inside the box body 10. The side portion of the box body 10 can be surrounded by a side panel 11, or can be formed by connecting multiple side panels 11. In order to facilitate installation and maintenance, in this embodiment, multiple side panels 11 are surrounded to form the side portion of the box body 10, and one side panel 11 can be opened and closed with other side panels 11. The bottom cover includes a bottom plate and a top cover 12, the bottom plate is installed on the mounting seat of the electrical box, the top cover 12 is covered in the receiving cavity and covers the receiving cavity, and the top cover 12 is connected to one end of the side panel 11 away from the bottom plate. Since the electrical box of the heat pump unit is large in size, and there are many electric control components 30, and the connection between the components is complicated, when the actual disassembly or maintenance operation is performed, when only one side panel 11 is opened, the internal light is dim, which is not convenient for the staff to install and repair the electric control components. Therefore, as a preferred embodiment, a detachable connection is adopted between the top cover 12 and the side panel 11. A connecting piece 121 is provided on the side of the top cover 12 facing the accommodating cavity, and a first mounting hole is opened on the connecting piece 121. A matching second mounting hole is provided on the end of the side panel 11 close to the top cover 12. The first mounting hole and the second mounting hole are arranged opposite to each other, and the connecting piece 121 is fixedly connected to the side panel 11 by screws, so as to realize the fixed connection between the top cover 12 and the side panel 11. It should be noted that at least two side panels 11 are fixedly connected to the top cover 12 to ensure the stability of the installation of the top cover 12.

[0049] Accordingly, before installing the entire electrical box in the heat pump unit box, the top cover 12 and the openable side panel 11 are opened at the same time. The staff can enter the box body 10 from one side of the opened side panel 11 for installation, or reach into the box body 10 from the top cover 12 for installation. The installation process is efficient and convenient. After the entire electrical box is installed in the heat pump unit box, when the electronic control component 30 needs to be repaired, the openable side panel 11 is opened first for maintenance. In order to avoid the accidental unplugging of the electrical connection wires due to the small maintenance space and dim internal light, the top cover 12 can be opened at the same time. On the one hand, sufficient light is provided for maintenance, and on the other hand, another maintenance window is provided to improve the convenience and efficiency of maintenance.

[0050] In other embodiments, the top cover 12 is connected to the side panel 11 by a snap connection structure. For example, matching protrusions and grooves are provided between the top cover 12 and the side panel 11, the protrusions are provided on the side of the top cover 12 facing the side panel 11, and the grooves are provided on the end surface of the side panel 11 facing one end of the top cover 12, or the protrusions are provided on the end surface of the side panel 11 facing one end of the top cover 12, and the grooves are provided on the side of the top cover 12 facing the side panel 11; for another example, matching hooks and holes are provided between the top cover 12 and the side panel 11, the hooks are provided on the side of the top cover 12 facing the side panel 11, and the holes are provided near the end of the side panel 11 facing the top cover 12, etc., but the present invention is not limited thereto.

[0051] Please refer to FIG. 4 . The installation component 20 is disposed in the accommodating cavity. The electric control component 30 includes a driving component 31 and a reactor 32 . The installation component 20 includes a plurality of installation members 21 . The plurality of installation members 21 are used to install the driving component 31 and the reactor 32 , respectively.

[0052] Specifically, the mounting member 21 is provided with a first mounting portion 211 and a second mounting portion 212. The first mounting portion 211 is connected to the side panel 11, one end of the second mounting portion 212 is connected to the first mounting portion 211, preferably connected as one piece, and the other end is extended toward the inside of the accommodating cavity. Preferably, the first mounting portion 211 and the second mounting portion 212 are both flat plates, the second mounting portion 212 is arranged at an angle to the first mounting portion 211, and the second mounting portion 212 and the first mounting portion 211 are preferably arranged vertically as one piece. It is understandable that the second mounting portion 212 can be arranged at one end of the first mounting portion 211 facing the top cover 12 or at one end away from the top cover 12, and the second mounting portion 212 can also be arranged between the two ends of the first mounting portion 211. As shown in FIG4(a), when the second mounting portion 212 is disposed at one end of the first mounting portion 211 away from the top cover 12, the electric control component 30 is disposed on the side of the first mounting portion 211 facing the accommodating cavity. At this time, it is suitable to install relatively light components. In this embodiment, the light driving component 31 is installed thereon; when the second mounting portion 212 is disposed at one end of the first mounting portion 211 facing the top cover 12, as shown in FIG4(b), the electric control component 30 is disposed on the second mounting portion 212. At this time, it is suitable to install components of various weights. In this embodiment, the heavier inductor 32 is installed thereon. In either case, the second mounting portion 212 can provide support for the electric control component 30, and when a component of the electric control component 30 falls, the second mounting portion 212 can receive the fallen component to prevent it from falling to the bottom of the electrical box and causing damage to other components.

[0053] Furthermore, a flange 2121 is provided on the edge of the second mounting portion 212, one end of the flange 2121 is connected to the second mounting portion 212, and the other end is extended toward the top cover 12 to better receive dropped parts. At the same time, the electrical connection lines of the electric control component 30 installed on the mounting part 21 of one of the side panels 11 can be concentrated in the area surrounded by the second mounting portion 212 and its flange 2121, so that the distribution of the electrical connection lines is more reasonable, and interference between the electrical connection lines caused by the disorder of the electrical connection lines can be prevented, and misconnection and misplugging during installation and disassembly can be avoided.

[0054] Please also see Figure 2 4, in a further embodiment, the side plate 11 connected to the first mounting portion 211 is set as the first side plate 111, and the side plate adjacent to the first side plate 111 is the second side plate 112. In order to improve the stability of the installation of a heavy component such as the reactor 32, the flange 2121 parallel to the second side plate 112 abuts against the second side plate 112. In the case where the second mounting portion 212 is arranged at one end of the first mounting portion 211 facing the top cover 12 or between the two ends of the first mounting portion 211, the flange 2121 parallel to the first side plate 111 abuts against the first side plate 111, and further, the flange 2121 and / or the second side plate 112 are fixedly connected. It can be understood that the flange 2121 abutting or fixedly connected to the first side plate 111 and the second side plate 112 can be set to a different size from the flanges of other edges according to actual stability requirements or space limitations.

[0055] When actually installing and disassembling the mounting member 21, since the mounting member 21 is installed with the electric control component 30 and is heavy, when fixing the mounting member 21 to the side panel 11, it is necessary to support the mounting member 21 and the electric control component 30 fixed thereon while installing it, which brings great inconvenience to the disassembly and assembly, and there is a risk of the electric control component 30 being damaged due to falling. In order to improve the disassembly and assembly efficiency and avoid the risk of falling, a supporting member 13 is provided on the side of the side panel 11 facing the accommodating cavity, and the supporting member 13 supports the mounting member 21 and the electric control component 30 provided on the mounting member 21 on the side panel 11.

[0056] One end of the supporting member 13 is connected to the side plate 11, and the other end is extended toward the mounting member 21. Preferably, the supporting member 13 is integrally connected with the side plate 11 to ensure the supporting force of the supporting member 13 on the mounting member 21 and the electric control component 30 disposed on the mounting member 21. The mounting member 21 is provided with a first through hole 21a matching the supporting member 13, and the supporting member 13 passes through the first through hole 21a, so that the mounting member 21 is pre-installed on the side plate 11, so that the mounting member 21 and the electric control component 30 are supported by the supporting member 13.

[0057] See also Figure 5During the disassembly and assembly operation, the mounting member 21 may be touched to some extent or vibration may be generated when plugging and unplugging the electrical connection wire. In order to prevent the supporting member 13 from being moved out of the first through hole 21a due to the touch or vibration, causing the mounting member 21 to be separated from the supporting member 13, the supporting member 13 and the side plate 11 are arranged in an inclined manner, and preferably, the inclination direction is toward the top of the box body 10. This prevents the supporting member 13 from being easily moved out of the first through hole 21a due to external force or vibration.

[0058] See also Figure 6 In another embodiment, the supporting member 13 is provided with a connecting portion 131 and a limiting portion 132. One end of the connecting portion 131 is connected to the side plate 11, and the other end is connected to the limiting portion 132. The limiting portion 132 is extended toward the top cover 12 from one end of the connecting portion 131. The shape and size of the first through hole 21a match the supporting member 13 so that the supporting member 13 can pass through the first through hole 21a. Preferably, the first through hole 21a is in a long strip shape, and its length direction is the extension direction from the bottom plate to the top cover 12. First, the supporting member 13 is passed from one side of the first through hole 21a toward the side plate 11 to the other side, and the mounting member 21 is loosened. Due to the action of gravity, the first through hole 21a moves downward relative to the supporting member 13, and the supporting member 13 moves upward relative to the first through hole 21a. Finally, the connecting portion 131 moves to the end of the first through hole 21a toward the top cover 12, and the limiting portion 132 abuts against the side of the mounting member 21 facing the inside of the accommodating cavity. Even if there is external force or vibration, it is difficult to move the supporting member 13 out of the first through hole 21a. The cross section of the supporting member 13 can be circular or square, preferably square, and the wall surface of the end of the first through hole 21a facing the top cover 12 is a plane, so that after the supporting member 13 is clamped in the first through hole 21a, the supporting member 13 abuts against the wall surface of the end of the first through hole 21a facing the top cover 12, avoiding the installation member 21 from rotating around the supporting member 13 in the case of an arc.

[0059] There are several supporting members 13 . Preferably, there are at least two supporting members 13 . The two supporting members 13 are arranged near the end of the side plate 11 facing the top cover 12 and are symmetrically arranged at intervals to better support the mounting member 21 .

[0060] Furthermore, after the mounting member 21 is supported on the supporting member 13, in order to fix the mounting member 21 to the side panel 11, a connection structure is further provided between the side panel 11 and the mounting member 21, and the side panel 11 and the mounting member 21 are fixedly connected via the connection structure. Specifically, the connection structure includes a second through hole, a third through hole, and a fixing member, the second through hole is provided on the side panel 11, the third through hole is provided on the mounting member 21, the second through hole and the third through hole are arranged opposite to each other, the fixing member is a screw or a bolt, and the shapes of the second through hole and the third through hole match the fixing member. The fixing member is inserted into the second through hole and the third through hole in sequence from the side plate 11 toward the outside of the accommodating cavity, so that the electric control component 30 disposed in the accommodating cavity can be conveniently installed and fixed from the outside of the electrical box. When maintenance is required, the fixing member can also be conveniently removed from the outside of the electrical box to release the connection between the mounting member 21 and the side plate 11. Because the supporting member 13 is supported, when the fixing member is removed, the electric control component 30 installed on the mounting member 21 can be guaranteed not to fall, which provides great convenience for installation and maintenance and disassembly. In a further embodiment, in order to prevent water from entering the electrical box and causing circuit failure, a waterproof member is provided at the connection between the fixing member and the second through hole, and the waterproof member is made of a material with good waterproof properties, preferably a soft rubber material.

[0061] See also Figure 1 and Figure 2 , the driving component 31 will generate a lot of heat during operation, and it is necessary to dissipate the heat to the outside of the electrical box in time to improve the performance and life of the driving component 31. Therefore, the electrical box mounting structure is also provided with a heat sink 40, which is installed on the side of the side plate 11 facing the outside of the accommodating cavity and is arranged opposite to the driving component 31. The heat sink 40 can be composed of a heat sink or a fluorine cold plate. In this embodiment, it is a fluorine cold plate, which has a good heat dissipation effect.

[0062] In addition, in order to make the heat sink 40 directly abut against the driving component 31 to enhance the heat dissipation effect, a first through hole is opened on the corresponding side panel 11, and a second through hole is opened on the mounting member 21, specifically, on the first mounting portion 211. The first through hole and the second through hole are arranged relatively to each other, and the size and shape of the through hole match the heat sink 40, so that one end of the heat sink 40 facing the side panel 11 passes through the first through hole and the second through hole and abuts against a side of the driving component 31 facing the side panel 11, specifically abuts against the mounting plate of the driving component 31.

[0063] Furthermore, after the heat sink 40 abuts against the mounting plate of the driving component 31, a gap will inevitably appear between the heat sink 40 and the mounting plate of the driving component 31, and the gap is filled with air, and the thermal conductivity of air is poor. In order to further improve the heat dissipation efficiency of the heat sink 40 to the driving component 31, a heat dissipation layer (not shown) is coated on the heat sink 40, and the thermal conductive layer is sandwiched between the heat sink 40 and the mounting plate of the driving component 31. The thermal conductive layer is preferably silicone grease, and the solution-like silicone grease is applied to the side of the heat sink 40 facing the driving component 31. After the heat sink 40 and the mounting plate of the driving component 31 abut against each other, the silicone grease can fully adhere to the heat sink 40 and the mounting plate of the driving component 31, and form a thermal conductive layer after solidification.

[0064] At the same time, the present application also provides a heat pump unit, including the electrical box installation structure described in the utility model.

[0065] Compared with the prior art, the beneficial effects of the technical solution of this application are:

[0066] (1) By installing the electric control component on the mounting component, and then fixing the mounting component to the side plate of the box body, the mounting component can be operated from the outside of the box body during disassembly and assembly, and a heat dissipation component for dissipating heat from the driving component can be conveniently arranged; at the same time, a supporting member is arranged on the side of the side plate facing the inside of the box body, and the mounting component and the electric control component are supported by the supporting member, so that the mounting component and the electric control component can be prevented from falling and causing damage to the components without manual lifting during disassembly and assembly, which facilitates the disassembly and assembly of the electric control component inside the electrical box, and improves the efficiency of installation and maintenance;

[0067] (2) The supporting member is integrally connected to the side plate, and the angle and shape of the supporting member are designed to improve the stability of the connection between the supporting member and the mounting assembly, thereby preventing the supporting member from being removed from the first through hole during disassembly and assembly, thereby preventing the mounting assembly and the electronic control assembly installed thereon from falling off;

[0068] (3) By setting up mounting parts of different structures, it can adapt to the installation of drive components and reactors of different weights, provide support for electronic control components and receive dropped components;
