Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, and in particular to a heat dissipation device for distribution boxes. Background Technology

[0002] A distribution box is a low-voltage power distribution device that assembles switching equipment, measuring instruments, protective electrical appliances, and auxiliary equipment in a closed or semi-closed metal cabinet or panel according to electrical wiring requirements. The electrical equipment installed inside the distribution box generates a lot of heat when it is working, and this heat needs to be dissipated in a timely manner to avoid affecting the electrical equipment.

[0003] Existing distribution boxes use air ducts inside the box to distribute cool air brought in by an external fan to cool electrical appliances. However, these heat dissipation structures accumulate dust over time, making them difficult to clean. Furthermore, when heat dissipation components are damaged, they are difficult to repair or replace. Utility Model Content

[0004] This invention addresses the problems of dust accumulation in existing distribution box heat dissipation structures, making cleaning difficult, and the difficulty in repairing or replacing damaged heat dissipation components. It proposes a heat dissipation device for distribution boxes.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a heat dissipation device for a distribution box, including a box with a front opening, a box door installed at the front opening of the box, and heat dissipation vents opened on the left and right sides of the box near the top and bottom ends, and a heat dissipation component installed inside the box, the heat dissipation component including a blower box inserted into the box from the rear side of the box, the blower box blowing air to the upper and lower sides, and a blower mechanism fixed at the rear end of the blower box.

[0006] As a preferred embodiment, the blower box has evenly arranged air holes on both the top and bottom sides, and an air inlet box is fixed at the rear end of the blower box. The blower mechanism is fixed at the rear port of the air inlet box, and a filter plate is installed inside the air inlet box from top to bottom.

[0007] As a preferred option, lock holes are provided on both the left and right sides of the air inlet box, and an insertion port is provided on the top side of the air inlet box.

[0008] As a preferred embodiment, the front side of the filter plate has evenly arranged air passage holes, and the rear side of the filter plate has a cavity, with filter cotton installed inside the cavity.

[0009] As a preferred embodiment, the blower mechanism includes a cover, on the surface of which multiple fans are mounted, and a locking plate is fixed to the front side of the cover near the left and right ends. The locking plate is threaded with a locking screw, and a pin is fixed to the end of the locking screw.

[0010] As a preferred option, the rear side of the enclosure is provided with an installation port, and the left and right side walls inside the enclosure are provided with guide slots.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The blower blows air into the air box and onto the top and bottom sides of the box to dissipate heat. When the heat dissipation structure needs to be cleaned, the entire heat dissipation component can be removed directly for cleaning, which also facilitates the repair and replacement of the heat dissipation component.

[0013] The air blower box uses air holes on the top and bottom sides to blow air evenly to the top and bottom sides, thereby dissipating heat from the electrical appliances on both sides over a large area. The hot air is then quickly discharged to the outside through the heat dissipation vents, which greatly improves the heat dissipation effect inside the distribution box. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0023] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0024] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0027] like Figure 1 and Figure 2 As shown, a heat dissipation device for a distribution box includes a box 1 with a front opening. A door 2 is installed at the front opening of the box 1, and heat dissipation vents 4 are provided on the left and right sides of the box 1 near the top and bottom ends. A heat dissipation component 3 is installed inside the box 1. The heat dissipation component 3 includes a blower box 31 inserted into the box 1 from the rear side. The blower box 31 blows air to the top and bottom sides, and a blower mechanism 33 is fixed at the rear end of the blower box 31. The blower mechanism 33 blows air into the blower box 31 and to the top and bottom sides of the box 1 to dissipate heat. When it is necessary to clean the heat dissipation structure, the entire heat dissipation component 3 can be directly removed for cleaning, which also facilitates the maintenance and replacement of the heat dissipation component 3.

[0028] like Figure 3 As shown, the blower box 31 has evenly arranged blow holes 313 on both the upper and lower sides. The blower box 31 uses the blow holes 313 on the upper and lower sides to blow air evenly to the upper and lower sides to dissipate heat from the electrical appliances on the upper and lower sides.

[0029] Furthermore, an air inlet box 311 is fixed to the rear end of the air blower box 31, and the air blower mechanism 33 is fixed at the rear port of the air inlet box 311. A filter plate 32 is installed inside the air inlet box 311 from top to bottom. The air blower mechanism 33 blows air into the air inlet box 311 and filters the incoming air through the filter plate 32.

[0030] like Figure 3As shown, the air inlet box 311 has lock holes 314 on both the left and right sides, and an insertion port 312 on the upper side of the air inlet box 311. The air inlet box 311 uses the insertion port 312 to install and fix the filter plate 32.

[0031] like Figure 4 As shown, the front side of the filter plate 32 is provided with evenly arranged air passage holes 322, and the rear side of the filter plate 32 is provided with a cavity. Filter cotton 321 is installed inside the cavity. The filter plate 32 uses the air passage holes 322 to realize the air circulation, and uses the filter cotton 321 to filter and block dust in the air.

[0032] like Figure 5 As shown, the blower mechanism 33 includes a cover 333, and multiple fans 334 are mounted on the surface of the cover 333. The fans 334 blow air into the air inlet box 311 and send it to the blower box 31 for heat dissipation.

[0033] Locking plates 331 are fixed to the front side of the cover 333 near the left and right ends. Locking screws 335 are threaded on the locking plates 331, and pins 332 are fixed to the ends of the locking screws 335. The cover 333 is fitted onto the air inlet box 311, and the pins 332 are inserted into the lock holes 314 for locking and fixing by turning the locking screws 335 on the locking plates 331.

[0034] like Figure 6 As shown, the rear side of the housing 1 is provided with an installation port, and the left and right side walls inside the housing 1 are provided with guide slots 11. The housing 1 uses the installation port to install the blower box 31, and the guide slots 11 are used to limit and fix the blower box 31 during installation.

[0035] In this embodiment, when dissipating heat from the electrical appliances inside the enclosure 1, a fan 334 blows air into the air inlet box 311 and into the air blower box 31. The air blower box 31 blows air into the air inlet box 311 and filters the incoming air through the filter plate 32. The filtered air is then evenly distributed to the upper and lower sides through the air blowing holes 313 on the upper and lower sides of the air blower box 31, thereby dissipating heat from the electrical appliances on the upper and lower sides. The hot air is then discharged to the outside through the heat dissipation vent 4, thus completing the heat dissipation of the electrical distribution box.

[0036] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
