Therefore, when the fan assembly radiates heat, the air flow blown to the electrical element with high dissipation power is high, and the air flow blown to the electrical element with low dissipation power is low, so that the phenomenon that heat radiation resources are wasted can be avoided to a certain extent.

Embodiments of the present application will be described in detail below with reference to the attached drawings and detailed description.

As shown in fig. 1 to 6, the present embodiment provides a cabinet assembly, including a cabinet body 1, the cabinet body 1 includes two cover plates 14 that are oppositely disposed and a plurality of enclosing plates 15 that enclose between the two cover plates 14, an installation cavity 11 is enclosed between the two cover plates 14 and the plurality of enclosing plates 15, and an air inlet 12 and an air outlet are respectively provided on the two enclosing plates 15 that are oppositely disposed, wherein, one cover plate 14 is rotatably connected with the enclosing plates 15, and can close or open the installation cavity 11.

In order to make greater use of the heat dissipation resources during the heat dissipation process in the cabinet 1, for example, the air flow through the electrical components with high dissipation power is greater than the air flow through the electrical components with low dissipation power.

From this, the cabinet body assembly that this embodiment provided can also include setting up the partition piece 2 in the installation cavity 11, partition piece 2 and cabinet body 1 cooperate to enclose into two mutually independent wind channel chambeies, for example be first wind channel chamber 4 and second wind channel chamber 5 in this embodiment, the both ends in first wind channel chamber 4 communicate with air intake 12 and air outlet respectively, the both ends in second wind channel chamber 5 communicate with air intake 12 and air outlet respectively, be used for holding first electrical components in the first wind channel chamber 4, be used for holding second electrical components in the second wind channel chamber 5, and the dissipation power of first electrical components and second electrical components is different.

Further, in order to enable the heat dissipation air flow, for example, low-temperature air flow, to pass through the first air channel cavity 4 and the second air channel cavity 5, the cabinet body assembly provided in this embodiment further includes a fan assembly 3, the fan assembly 3 may be disposed at the position of the air inlet 12 or the air outlet, and the fan assembly 3 is used for driving the external air flow to enter from the air inlet 12, and after passing through the first air channel cavity 4 and the second air channel cavity 5, the external air flow is discharged from the air outlet.

In order to vary the amount of airflow through the first electrical component and the second electrical component, in this embodiment, the cabinet assembly is configured such that the amount of airflow through the two air duct chambers is different and the amount of airflow through each air duct chamber is positively correlated to the dissipated power of the electrical component located within the air duct chamber. That is, when the power consumption of the first electrical component is greater than that of the second electrical component, the air flow through the first air channel cavity 4 is greater than that through the second air channel cavity 5; when the power consumption of the first electrical component is smaller than that of the second electrical component, the air flow through the first air channel cavity 4 is smaller than that through the second air channel cavity 5. Like this, in the cabinet body subassembly that this embodiment provided, when dispelling the heat through fan subassembly 3, blow the air current on the electrical components that the dissipation power is big, blow the air current on the electrical components that the dissipation power is little, then can avoid appearing the phenomenon that the heat dissipation resource was wasted to a certain extent, that is to say, can reach directional radiating effect to a certain extent according to different electrical components.

When the air flow amount blown to the electric device with large dissipation power needs to be larger than the air flow amount blown to the electric device with small dissipation power, the opening area of the air inlet corresponding to the electric device with large dissipation power may be larger than the opening area of the air inlet corresponding to the electric device with small dissipation power, or the shielding member may be provided at the air inlet corresponding to the electric device with small dissipation power, or the power of the fan assembly corresponding to the electric device with large dissipation power may be larger than the power of the fan assembly corresponding to the electric device with small dissipation power. In this case, there is no limitation on the implementation of the different air flows to the electrical components of different dissipated power.

Wherein, the electric appliance element with large dissipation power and the electric appliance element with small dissipation power can share one fan assembly 3, and can also be respectively provided with the fan assemblies 3, when sharing one fan assembly 3, the difference of air flow can be realized by limiting the opening area of the air inlet 12; when the fan assemblies 3 are provided separately, the powers of the two fan assemblies 3 can be made different to achieve the difference in the air flow rate.

The following description will take an example of the difference in opening areas of the common air inlet assembly 3 and the air inlet 12.

In order to achieve a large air flow to the electrical components with large dissipation power and a small air flow to the electrical components with small dissipation power, the air flow into the corresponding air duct cavity can be limited. Thus, the air inlet 12 may include the first air inlet 121 and the second air inlet 122 with different opening areas, and it is specifically understood that the first air inlet 121 may be one or more, and the second air inlet 122 may be one or more. When the first air inlet 121 and the second air inlet 122 are both one, the opening area of the first air inlet 121 should be different from the opening area of the second air inlet 122; when the first air inlet 121 and the second air inlet 122 are plural, the difference of the opening areas can be understood that the sum of the opening areas of the first air inlets 121 is different from the sum of the opening areas of the second air inlets 122. Here, the number of the first air inlets 121 and the second air inlets 122 is not limited.

In some specific embodiments, one end of the first air channel cavity 4 is communicated with the first air inlet 121, and the other end of the first air channel cavity 4 is communicated with the air outlet; one end of the second air channel cavity 5 is communicated with the second air inlet 122, and the other end of the second air channel cavity 5 is communicated with the air outlet; the opening area of the first air inlet 121 is positively correlated with the dissipated power of the first electrical component, and the opening area of the second air inlet 122 is positively correlated with the dissipated power of the second electrical component. That is, when the dissipated power of the first electrical component is greater than that of the second electrical component, the opening area of the first air inlet 121 is greater than that of the second air inlet 122; when the dissipated power of the first electrical component is smaller than that of the second electrical component, the opening area of the first air inlet 121 is smaller than that of the second air inlet 122. In this way, by limiting the opening area of the air inlet 12 that the corresponding air duct cavity communicates with, the air flow flowing through the corresponding air duct cavity can be positively correlated with the opening area of the corresponding air inlet 12.

It should be noted that, in some embodiments, the ratio of the opening area of the first air inlet 121 to the opening area of the second air inlet 122 is a preset ratio, for example, in this embodiment, the ratio of the opening area of the first air inlet 121 to the opening area of the second air inlet 122 may be 1:4, that is, the ratio of the air flow in the first air duct cavity 4 to the air flow in the second air duct cavity 5 is 1:4. The ratio of the opening area of the first air inlet 121 to the opening area of the second air inlet 122 is determined according to the layout of the electrical components in the actual cabinet 1, and is not particularly limited herein.

When the opening area of the first air inlet 121 is smaller than the opening area of the second air inlet 122, it indicates that the dissipation power of the first electrical component is smaller than the dissipation power of the second electrical component, and in some embodiments, the first electrical component with smaller dissipation power may include the power panel 6, and the second electrical component with larger dissipation power may include the capacitor 7. Here, the types of the first electrical component and the second electrical component are not limited.

Referring to fig. 1 to 7, fig. 7 is a schematic structural diagram of an air duct cavity formed by a partition member and a cabinet body in a cabinet body assembly according to an embodiment of the present application. As shown in fig. 1 to 7, two ends of the partition 2 extend toward the air inlet 12 and the air outlet respectively, specifically, one end of the partition 2 extends toward the air inlet 12 to separate the first air inlet 121 from the second air inlet 122, so that the first air inlet 121 and the second air inlet 122 are respectively located in different areas on two sides of the partition 2, that is, the first air inlet 121 and the second air inlet 122 are arranged at intervals in a direction perpendicular to the extending direction of the partition 2; the other end of the partition 2 extends towards the air outlet and has a gap with the shroud 15 provided with the air outlet, at least part of the fan assembly 3 being located in the gap, i.e. part of the structure of the fan assembly 3 extending into the mounting cavity 11.

Wherein, fan assembly 3 includes fixed frame 31 and sets up the fan 32 in fixed frame 31, and wherein, fixed frame 31 cooperates with the air outlet in order to be connected with cabinet 1 detachably, and fan 32 sets up in fixed frame 31.

In order to further improve the utilization ratio of the heat dissipation resources, in some optional embodiments, the first air duct cavity 4 and the second air duct cavity 5 may share one fan assembly 3, specifically, one end of the partition 2 extending towards the air outlet may divide the fan 32 into two air passing areas, the two air passing areas are arranged along a direction consistent with the arrangement direction of the two air duct cavities, and in the arrangement direction of the two air duct cavities, the opening area of each air passing area is positively correlated with the dissipation power of an electrical component in the corresponding air duct cavity, that is, when the dissipation power of the first electrical component is greater than that of the second electrical component, the opening area of the air passing area communicated with the first air duct cavity 4 is greater than that of the air passing area communicated with the second air duct cavity 5; when the dissipated power of the first electrical component is smaller than that of the second electrical component, the opening area of the air passing area communicated with the first air duct cavity 4 is smaller than that of the air passing area communicated with the second air duct cavity 5. In this way, by limiting the opening area of the over-air region on the blower 32 that communicates with the air duct cavity, the amount of airflow to the air duct cavity can also be limited, so that the heat sink resources are utilized to a greater extent.

In this embodiment, the number of the fans 32 may be two, and the arrangement direction of the two fans 32 is perpendicular to the arrangement direction of the two air duct cavities. Here, the number and arrangement direction of the fans 32 are not limited.
