Description

Technical Field

[0001] This utility model relates to the field of enclosures, and more specifically, to a heat dissipation enclosure. Background Technology

[0002] The electrical control cabinets of screw air compressors are typically quite short, making it difficult for the control panel or display screen to be directly adapted to the worker's height. Therefore, during installation or assembly, the control assembly is often elevated. Furthermore, for control cabinets used for extended periods, ventilation holes are necessary to improve heat dissipation. However, these holes may compromise the protection of internal electrical components, leading to decreased sensitivity or accuracy over time, requiring periodic maintenance. To increase maintenance intervals, the ventilation holes must be covered when the machine is shut down. Currently, the height adjustment of the cabinet and the covering of the ventilation holes are functionally independent, resulting in a complex structure. Utility Model Content

[0003] The purpose of this utility model is to provide a heat dissipation box that solves the problem that the height adjustment of the box and the blocking of the heat dissipation holes are independent in function, resulting in a more complex structure in the prior art.

[0005] A heat dissipation enclosure includes: a heat dissipation plate and a baffle. The heat dissipation plate has a plurality of heat dissipation holes and has a longitudinal degree of freedom of movement. The outer side wall of the heat dissipation plate is provided with an upper limit plate and a lower limit plate. The baffle includes: a middle plate and side plates located on both sides of the width direction of the middle plate. The middle plate is slidably connected to the outer side wall of the heat dissipation plate. The middle plate has a longitudinal degree of freedom of movement. The side plates are provided with an upper support block and a lower support block. The top wall of the upper support block abuts against the bottom wall of the upper limit plate. The top wall of the lower support block abuts against the bottom wall of the lower limit plate. A heat dissipation channel is formed between the upper support block and the lower limit plate, and the heat dissipation channel communicates with the heat dissipation holes. The side plates have a longitudinal degree of freedom of movement.

[0006] Preferably, the middle plate has a longitudinal groove on the side near the heat sink, the upper end of the groove is an open end and the lower end of the groove is a closed end; the upper end of the heat sink has a slider that cooperates with the groove; the lower end of the heat sink has a support plate that cooperates with the bottom wall of the middle plate.

[0007] Preferably, the width of the slider gradually increases as it extends in a direction away from the heat sink.

[0008] Preferably, the slide groove has openings on both sides in the width direction, and the width of the openings is less than the thickness of the slider; the openings are connected to the heat dissipation channel.

Detailed Implementation

[0024] To make the objectives, methods, and advantages of the embodiments of this utility model clearer, the methods in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0025] Example 1: As Figure 1-4 As shown, a heat dissipation box includes: a heat dissipation plate 1 and a baffle 2. The heat dissipation plate 1 is provided with a plurality of heat dissipation holes 11 and has a longitudinal degree of freedom of movement. The outer side wall of the heat dissipation plate 1 is provided with an upper limit plate 12 and a lower limit plate 13. The baffle 2 includes: a middle plate 21 and side plates 22 located on both sides of the width direction of the middle plate 21. The middle plate 21 is slidably connected to the outer side wall of the heat dissipation plate 1. The middle plate 21 has a longitudinal degree of freedom of movement. The side plates 22 are provided with an upper support block 221 and a lower support block 222. The top wall of the upper support block 221 abuts against the bottom wall of the upper limit plate 12. The top wall of the lower support block 222 abuts against the bottom wall of the lower limit plate 13. A heat dissipation channel 3 is formed between the upper support block 221 and the lower limit plate 13, and the heat dissipation channel 3 communicates with the heat dissipation holes 11. The side plates 22 have a longitudinal degree of freedom of movement.

[0026] In specific implementation, the longitudinal freedom of movement of the heat sink 1, middle plate 21, and side plate 22 can be achieved by telescopic cylinders or hydraulic cylinders. To allow the height of the electrical control box to be adjusted according to the height of different operators, the height of the heat sink 1 is adjustable in this embodiment. However, to achieve stable support for the box, at least two telescopic cylinders are usually symmetrically installed below the box. Therefore, to further adjust the height of the baffle 2, an additional cylinder is needed. In this embodiment, after designing the baffle 2 as a side plate 22 and a middle plate 21, as... Figure 3 As shown, the upper support block 221 on the side plate 22 can support the upper limit plate 12 on the heat dissipation plate 1, and the lower support block 222 can support the lower limit plate 13. When setting the telescopic cylinder under the box, a telescopic cylinder can be set on the side of the box that is away from the heat dissipation plate 1. Then, the support block on the side plate 22 can support the other side of the box. The telescopic cylinder and the side plate 22 can achieve the overall support of the box. The device that realizes the lifting of the side plate 22, such as the telescopic cylinder, can not only realize the height adjustment of the side plate 22, but also serve as one of the sources of the box's load-bearing capacity.

[0027] When heat dissipation is required, the movable middle plate 21 exposes the heat dissipation holes 11. After a cooling fan is installed inside the casing, hot air can be dissipated through the heat dissipation holes 11. In order to increase the distribution area of ​​the heat dissipation holes 11 and enhance heat dissipation, in this embodiment, the side plate 22 and the heat sink 1 are not directly in contact, but an opening is left as shown in the figure. Figure 3 As shown in the heat dissipation channel 3, when the middle plate 21 is opened, the heat dissipation holes 11, which are covered by the side plate 22, are directly connected to the outside atmosphere through the heat dissipation channel 3. This allows hot air to flow towards the middle plate 21 via the heat dissipation channel 3, achieving heat dissipation. During heat dissipation, only a portion of the heat dissipation holes 11 are exposed, further improving the dustproof effect.

[0028] Example 2: To improve the stability of the movement of the middle plate 21 and reduce the adjustment of the height of the middle plate 21, improvements were made based on Example 1, such as... Figure 4-5 As shown, in this embodiment, the middle plate 21 is provided with a longitudinal groove 211 on the side near the heat sink 1. The upper end of the groove 211 is an open end, and the lower end of the groove 211 is a closed end. The upper end of the heat sink 1 is provided with a slider 14 that cooperates with the groove 211. The lower end of the heat sink 1 is provided with a support plate 15 that cooperates with the bottom wall of the middle plate 21.

[0029] In practice, when adjusting the height of the enclosure, the support plate 15 can move the middle plate 21 along with the enclosure. When heat dissipation is required, the longitudinal movement of the middle plate 21 is more stable with the cooperation of the slider 14 and the slide groove 211.

[0030] Example 3: To prevent the middle plate 21 from tipping over, improvements were made based on Example 2, such as... Figure 6As shown in this embodiment, the width of the slider 14 gradually increases as it extends in a direction away from the heat sink 1.

[0031] In practice, the cross-section of the slider 14 can be trapezoidal. By utilizing the cooperation between the slider 14 and the slide groove 211, the slider 14 can only disengage from the slide groove 211 through longitudinal movement, thereby preventing the middle plate 21 from disengaging from the heat sink 1 and improving the stability of the relative position between the middle plate 21 and the housing when the middle plate 21 rises and falls with the housing.

[0032] Example 4: An improvement was made based on Example 2, such as... Figure 7 As shown, in this embodiment, the slide groove 211 has openings 2111 on both sides in the width direction, and the width of the openings 2111 is smaller than the thickness of the slider 14; the openings 2111 are connected to the heat dissipation channel 3.

[0033] In practical implementation, when heat dissipation is required, the movement of the side plate 22 and / or the middle plate 21 can expose the heat dissipation holes 11, enabling the heat dissipation holes 11 to communicate with the external environment. Therefore, this embodiment provides a structure that allows heat dissipation through the movement of the side plate 22. For example, when two telescopic cylinders are used for stable support at the bottom of the enclosure, the relative position between the side plate 22 and the heat dissipation plate 1 can be changed through the cylinders of the side plate 22. The method of exposing the heat dissipation holes 11 by moving the side plate 22 downwards can also reduce the vertical space occupied by the enclosure to some extent. After providing an opening 2111 on the side wall of the slide 211, the internal space of the slide 211 can communicate with the external environment through the opening 2111, allowing the portion of the heat dissipation holes 11 covered by the middle plate 21 to also communicate smoothly with the external environment, increasing the heat dissipation area.

[0034] Example 5: To increase the structural stability of baffle 2, improvements were made based on Example 1, such as... Figure 6 As shown, in this embodiment, the side wall of the middle plate 21 in the width direction is provided with a limiting block 212, and the side plate 22 is provided with a limiting groove 223 that cooperates with the limiting block 212.

[0035] In the specific implementation process, since there will be a certain relative displacement between the middle plate 21 and the side plate 22, in order to increase the connection stability between the two, this embodiment sets a limiting block 212 and a limiting groove 223. Through the cooperation of the limiting block 212 and the limiting groove 223, the stability of the side plate 22 or the middle plate 21 when moving can be increased or decreased, and the overall structural stability of the baffle 2 can be increased.

[0036] Example 6: As Figure 1As shown, in this embodiment, the heat dissipation box further includes: an outer shell 4, a lifting plate 5, and a driving mechanism 6. The heat dissipation plate 1 is disposed on the side wall of the outer shell 4; the lifting plate 5 is installed on the bottom wall of the outer shell 4; and the output end of the driving mechanism 6 is connected to the side plate 22.

[0037] In practice, the back panel of the outer casing 4 can directly use the heat dissipation plate 1. A cylinder can be installed below the lifting plate 5 to raise and lower the lifting plate 5, thereby achieving overall height adjustment of the outer casing 4. The drive mechanism 6 can also use a telescopic cylinder to raise and lower the side plate 22.

[0038] Example 7, in order to simplify the synchronous movement of the two side plates 22 and reduce the use of the drive device 61, was improved based on Example 6, such as... Figure 1 As shown, in this embodiment, the driving mechanism 6 includes: a driving device 61, an integrated plate 62, and a connecting rod 63. The output end of the driving device 61 extends longitudinally; the integrated plate 62 is connected to the driving device 61; and the side plate 22 is connected to the integrated plate 62 via the connecting rod 63.

[0039] In practice, the drive device 61 can be a telescopic cylinder or a hydraulic cylinder. Since there are two side plates 22 in this embodiment, although each side plate 22 could be moved by a telescopic cylinder, the cost would be high. In this embodiment, after connecting the output end of the telescopic cylinder to the integrated plate 62, the movement of the side plate 22 can be achieved by moving the integrated plate 62.

[0040] Example 8: To improve the stability of the movement of the outer casing 4, improvements were made based on Example 7, such as... Figure 1 As shown, in this embodiment, it further includes: a ring frame 7, the inner sidewall of which is slidably connected to the lifting plate 5; and the driving device 61 is installed on the top wall of the ring frame 7.

[0041] In practice, plates can be installed at the front and rear of the lower side of the ring frame 7 to shield the telescopic cylinder below the lifting plate 5. The sliding connection structure is existing technology. A slide rail can be installed on the inner wall of the ring frame 7, and a slider 14 can be installed on the side wall of the lifting plate 5. The stability of the lifting plate 5 during movement is ensured by the cooperation of the slide rail and the slider 14.

[0042] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
