[0032] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0034] In the description of this application, "several" means one or more, "more" means at least two, "greater than", "less than", "exceed", etc. are understood to exclude the number itself, and "above", "below", "within", etc. are understood to include the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0035] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application after combining the specific content of the technical solution.

[0036] Reference Figures 1 to 3 The additional heat dissipation device of the first aspect of the present application is applied to the exhaust heat dissipation of the electrical control cabinet and is suitable for being installed on the control cabinet. The additional heat dissipation device includes an additional shell 100, a connecting structure 200, a ventilation structure 300 and a heat dissipation assembly 400.

[0037] The additional shell 100 has an installation cavity 110, and the bottom surface of the additional shell 100 is provided with an air inlet 120 connected to the installation cavity 110; a connecting structure 200 is arranged on the additional shell 100, and the connecting structure 200 is used to be installed on the control cabinet; a ventilation structure 300 is arranged on the side wall of the additional shell 100; and a heat dissipation component 400 is arranged on the additional shell 100 and is located in the installation cavity 110, and the heat dissipation component 400 is used to extract the air of the control cabinet and discharge it from the ventilation structure 300.

[0038] It is understandable that by installing an additional heat sink on a control cabinet with insufficient heat dissipation capacity, the problem of insufficient heat dissipation capacity can be solved by installing an independent heat sink. Specifically, a hole is opened at a suitable position on the control cabinet, either a round hole or a square hole, and the size of the hole can be covered by the air inlet 120. The air inlet 120 is covered on the opening of the control cabinet, and then the additional heat sink is fixed to the control cabinet through the connecting structure 200, and the power cord of the heat dissipation component 400 is connected. At this time, the entire installation process is completed and it can be used after power is turned on. Preferably, this additional heat sink is fixed to the control cabinet by a detachable connection method, which is more convenient and quick to install.

[0039] Reference Figures 1 to 3 The additional heat dissipation device of the first aspect of the present application embodiment can be installed on a control cabinet with insufficient heat dissipation capacity. The design of the connecting structure 200 makes the installation convenient and quick, and is basically not restricted by site conditions. By opening a hole at a suitable position on the control cabinet and aligning the air inlet 120 with the hole position, the heat of the control cabinet can be discharged from the ventilation structure 300 through the heat dissipation component 400, thereby effectively solving the problem of insufficient heat dissipation capacity of the control cabinet itself.

[0040] In some embodiments, the additional housing 100 is configured as a rectangular box-shaped structure, which is easy and quick to install and can be easily covered on the opening of the control cabinet to ensure the heat dissipation effect of the installed heat dissipation device. In other embodiments, the additional housing 100 can also be configured as a structure of other specifications and shapes to adapt to control cabinets of different specifications and broaden the applicable scenarios.

[0041] In some embodiments of the present application, the air inlet 120 is suitable for covering the opening position of the control cabinet, and the heat dissipation component 400 is covered on the air inlet 120. It can be understood that the heat dissipation component 400 is directly arranged at the air inlet 120, and the air inlet 120 covers the opening position of the control cabinet to ensure that the heat to be dissipated can enter the air inlet 120 in time and be discharged through the heat dissipation component 400.

[0042] In some embodiments, the heat dissipation assembly 400 is a heat dissipation fan, which is convenient for installation at the air inlet 120 , saves costs, and does not temporarily use the installation cavity 110 space of the additional shell 100 , thereby meeting the requirement of a small volume of the additional shell 100 .

[0043] In some embodiments, two air inlets 120 are provided and spaced apart from each other, and the heat dissipation assembly 400 is provided on each air inlet 120. It is understandable that providing multiple air inlets 120 and heat dissipation assemblies 400 can improve the efficiency of heat dissipation. For this reason, the air inlets 120 and heat dissipation assemblies 400 are spaced apart from each other, so as to dissipate heat at different positions of the control cabinet at the same time, making the heat dissipation more uniform and rapid. For this reason, holes also need to be opened at two appropriate positions on the control cabinet, and then each air inlet 120 corresponds to each opening position, and then the additional housing 100 is installed on the control cabinet.

[0044] In some embodiments of the present application, the connection structure 200 includes a flange 210 arranged around the edge of the additional housing 100, and a plurality of mounting holes 220 for installation are provided on the flange 210. It can be understood that the flange 210 is easy to be formed on the additional housing 100, and is also very convenient when actually used on site, and improves the efficiency of fixing the additional housing 100 on the control cabinet, wherein the mounting hole 220 can be a through hole or a threaded hole, and during installation, the additional housing 100 can be installed on the control cabinet by respectively passing the connecting piece through the mounting hole 220 of the flange 210 and the connecting hole on the control cabinet.

[0045] In some embodiments, the additional housing 100 and the flange 210 are an integrated structure and are formed by stamping. In other embodiments, the additional housing 100 and the flange 210 are fixedly connected by threaded connection, welding, snap connection or bonding, so that the flange 210 is formed on the additional housing 100. The specific setting method can be selected according to actual conditions and will not be repeated here.

[0046] In some embodiments, the mounting holes 220 are evenly arranged on the flange 210 , which facilitates installation and ensures smooth installation of the additional housing 100 .

[0047] In some embodiments of the present application, the ventilation structure 300 includes a plurality of ventilation holes 310, each of which is arranged in an array on at least one side wall of the additional housing 100. It can be understood that the design of the ventilation holes 310 can timely discharge the wind drawn from the control cabinet by the heat dissipation assembly 400 to the outside of the additional housing 100 to achieve efficient heat dissipation.

[0048] In some embodiments, the ventilation structures 300 are respectively arranged on the front and side surfaces of the additional housing 100. It can be understood that by providing two ventilation structures 300, the efficiency of ventilation and heat dissipation is ensured, and the heat dissipation function of the control cabinet is improved.

[0049] In some embodiments, three columns and three rows of ventilation holes 310 are formed on the front of the additional housing 100, and two columns and three rows of ventilation holes 310 are formed on the side of the additional housing 100, thereby meeting ventilation and heat dissipation requirements.

[0050] In some embodiments, the ventilation holes 310 are configured as slots, which are horizontally extended to achieve normal ventilation and heat dissipation effects. In other embodiments, the ventilation holes 310 can be configured as square holes, circular holes, polygonal holes, etc., which can be selected and used according to actual conditions, and can be directly processed and formed on the additional housing 100.

[0051] In some embodiments of the present application, a waterproof sealing strip 500 is provided between the connection structure 200 and the control cabinet. The provision of the waterproof sealing strip 500 satisfies the requirements of outdoor rainproof installation, ensuring that the additional heat dissipation device does not affect the normal and safe use of the control cabinet. In some embodiments, a corresponding rainproof component can also be provided on the ventilation structure 300 to further improve the rainproof effect.

[0052] Reference Figures 1 to 3 The additional heat dissipation device of the first aspect of the present application is based on practicality and convenient installation, and is designed to be an integrated, detachable, rainproof additional heat dissipation device outside an independent control cabinet. It has a small size and an integrated design; it can be flexibly installed and is not restricted by the control cabinet and site conditions; it has a high protection level and rainproof function, and can meet the requirements of outdoor rainproof installation; it can be mass-produced and stocked; and a variety of heat dissipation specifications are available.

[0053] Reference Figures 1 to 3 The control cabinet of the second aspect of the present application can be an electrical control cabinet, such as a frequency conversion control cabinet, a soft start control cabinet, and a low-voltage capacitor compensation cabinet. The control cabinet includes the heat dissipation device of the first aspect of the present application, which can be flexibly installed without being restricted by the control cabinet, thereby solving the problem of insufficient heat dissipation capacity of some cabinets.

[0054] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present application.
