Description

Technical Field

[0001] The utility model belongs to the field of heat dissipation, in particular to a heat dissipation structure of a distribution box. Background Art

[0002] A distribution box is a complete set of equipment used to centrally install switches, instruments and other equipment. It usually contains switches, circuit breakers, measuring instruments, protective devices and auxiliary equipment. The size, model and structure of the distribution box vary depending on the application and requirements.

[0003] The distribution box itself is often installed outdoors for use. In the hot summer weather, the heat dissipation problem is difficult to solve because the general distribution box only uses some heat dissipation slots for natural heat dissipation.

[0004] In order to solve the heat dissipation problem, a Chinese patent with publication number CN210246066U discloses a heat dissipation distribution box, which performs heat dissipation by installing a fan inside the distribution box. However, the fan can only perform air extraction or blowing operation inside the box, and cannot form a circulating air duct, so the heat dissipation effect is not significantly improved. Utility Model Content

[0005] Technical problem to be solved: How to effectively dissipate heat in the distribution box.

[0006] Technical solution: The utility model provides a heat dissipation structure of a distribution box, including a main component and an air duct component: the main component includes a box body, a box door and a building block fan composed of an outer frame and a fan, air ducts are provided on both sides of the box body, and slide grooves along the width direction are provided at the top and bottom ends of the box body; the air duct component includes two partitions connected by slide groove clamping, and mounting grooves are provided on the partitions, and a detachable connecting mechanism is provided in the mounting groove for installing the building block fan, and the wind directions on one side of the two groups of building block fans are opposite.

[0007] Furthermore, the connecting mechanism includes a thin-walled plate connected to the top and bottom of the installation groove, and plate holes are symmetrically opened on the thin-walled plate; in addition, connecting holes are opened through the four corners of the outer frame of the building block fan, so that it can be connected to the thin-walled plate through the connecting holes and the plate holes and the connecting screws.

[0008] Furthermore, the partition is an aluminum plate, and a plurality of evenly distributed convex strips are formed on the sides of the two aluminum plates that are away from each other, and these convex strips together with the aluminum plates form a heat dissipation armor.

[0009] Furthermore, the top and bottom ends of the partition are both installed with sliding bars of the same length, and the sliding bars are slidably connected in the corresponding sliding grooves.

[0010] Furthermore, a sunken groove is formed on the inner wall of the box body at a position corresponding to the wind groove, and an adsorption mechanism connected to a filter is arranged in the sunken groove.

[0011] Furthermore, the adsorption mechanism includes thin magnetic sheets connected to the four corners of the inner side of the filter; in addition, the sunken groove is constructed on the inner side of the wind groove to form a groove wall, and a thin magnetic sheet is also provided on the groove wall for adsorbing the thin magnetic sheet on the filter.

[0012] Technical effects:

[0013] 1. In the utility model, two partitions divide the inner part of the box into three areas, the middle area is used to install components, and the areas on both sides are used as air ducts. Because the wind directions on the sides where the two groups of building block fans are close to each other are opposite, one group of building block fans sucks the cold air from the outside and blows it into the box, and the other group of building block fans draws the hot air from the inside of the box to the outside. The drawn air and the exhausted air are buffered by the two side areas respectively. The buffer on the side of the hot air exhaust can separate the hot air from the middle area through the partition on that side. Because the wind trough cannot discharge all the hot air at one time, it has an exhaust process, so it is necessary to block the hot air that has not been discharged yet. The buffer on the side of the cold air extraction is mainly to allow a part of the smoke and dust impurities drawn in to fall between the partition on that side and the box wall, thereby reducing the amount of smoke and dust impurities entering the middle area.

[0014] 2. In the utility model, the sunken groove formed by the structure on the inner side of the wind slot is connected to a filter to filter the external smoke and dust, further reducing the amount of smoke and dust entering the interior of the box. At the same time, since the filter is located in the area on both sides, even if the filter absorbs too much smoke and dust, most of the excess smoke and dust will still fall into the area on both sides, and the amount entering the middle area will be very small, which also reduces the amount of smoke and dust entering the middle area to a certain extent.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0022] The heat dissipation structure of the distribution box provided in this specific embodiment is as follows: Figure 2 and Figure 3 As shown, it includes a main body component and an air duct component, wherein:

[0023] The main components include a box body 1, a box door 2, and a building block fan 4 composed of an outer frame and a fan. The building block fan 4 is an existing public structure and will not be described in detail here. In addition, on the one hand, air ducts 3 are provided on both sides of the box body 1, and on the other hand, slide grooves 5 along the width direction are provided at the top and bottom of the box body 1.

[0024] The air duct component includes two partitions 6 connected by a slide groove 5. Specifically, the top and bottom ends of the partitions 6 are both installed with slide bars 601 of equal length, and the slide bars 601 are slidably connected in the corresponding slide grooves 5. In addition, the partitions 6 are provided with mounting grooves 7, and a detachable connection mechanism 8 is provided in the mounting grooves 7 for mounting the building block fans 4. The wind directions on one side of the two sets of building block fans 4 are opposite to each other. Because the wind directions on the side where the two groups of building block fans 4 are close to each other are opposite, one group of building block fans 4 draws cold air from the outside and blows it into the inside of the box body 1, and the other group of building block fans 4 draws hot air from the inside of the box body 1 and blows it to the outside. The extracted air and the exhausted air are buffered by the two side areas respectively. The buffer on the hot air exhaust side can separate the hot air from the middle area through the partition 6 on that side. Because the wind trough cannot discharge all the hot air at one time, it has an exhaust process, so it is necessary to block the hot air that has not been discharged yet. The buffer on the cold air extraction side is mainly to allow a part of the smoke and dust impurities drawn in to fall between the partition 6 on that side and the wall of the box body 1, thereby reducing the amount of smoke and dust impurities entering the middle area.

[0025] like Figure 4As shown, the above-mentioned connecting mechanism 8 includes a thin-walled plate 801 connected to the top and bottom of the installation groove 7, and plate holes 802 are symmetrically opened on the thin-walled plate 801; in addition, connecting holes 803 are opened through the four corners of the outer frame of the building block fan 4, so that it can be connected to the thin-walled plate 801 through the connecting holes 803 and the plate holes 802 with connecting screws.

[0026] To further improve the heat dissipation effect, such as Figure 3 As shown, the partition 6 can be an aluminum plate, and a plurality of evenly distributed convex strips 9 are formed on the side of the two aluminum plates away from each other. These convex strips 9 together with the aluminum plates form a heat dissipation armor, which can absorb heat and improve the heat dissipation performance.

[0027] It is worth mentioning that a recessed groove 10 is formed on the inner wall of the box body 1 at a position corresponding to the air groove 3. Figure 4 As shown, an adsorption mechanism is provided in the recessed groove 10 and connected to the filter 11. Specifically, the adsorption mechanism includes thin magnetic sheets connected to the four corners of the inner side of the filter 11. In addition, the recessed groove 10 is constructed on the inner side of the wind groove 3 to form a groove wall, and a thin magnetic sheet is also provided on the groove wall for adsorbing the thin magnetic sheet on the filter 11. In this way, the filter 11 can filter the external smoke and dust, further reducing the amount of smoke and dust entering the interior of the box 1. At the same time, since the filter 11 is located in the area on both sides, even if the filter 11 adsorbs too much smoke and dust, most of the excess smoke and dust will still fall into the area on both sides, and the amount entering the middle area will be very small, which also reduces the amount of smoke and dust entering the middle area to a certain extent.
