Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation of distribution cabinets, in particular to an outdoor explosion-proof distribution cabinet with a heat dissipation function. Background Art

[0002] An outdoor explosion-proof distribution cabinet is a distribution cabinet used in outdoor environments that can prevent explosions caused by explosive gases, vapors or dust. When the outdoor explosion-proof distribution cabinet is operating, it will generate a certain amount of heat. Moreover, the cabinet body of the distribution cabinet is usually assembled by cold-rolled steel plates, resulting in poor overall heat dissipation performance of the cabinet body. At present, in order to avoid the accumulation of heat in the distribution cabinet, heat dissipation fans are usually installed on the cabinet body. Although the heat dissipation fans can extract the heat inside the cabinet body, their heat dissipation function is single and the heat dissipation efficiency is relatively low. Especially when used in high-temperature environments in summer, it is very difficult to reduce the temperature inside the cabinet body in time only by the heat dissipation fans, which easily leads to too high temperature inside the distribution cabinet, affecting the normal operation of the equipment, shortening the service life, and even possibly causing potential safety hazards.

Specific embodiments

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Existing outdoor explosion-proof distribution cabinets usually install cooling fans on the cabinet body. Although the cooling fans can extract the heat inside the cabinet body, their heat dissipation function is single and the heat dissipation efficiency is relatively low. Especially when used in high-temperature environments in summer, it is very difficult to quickly reduce the temperature inside the cabinet body only by the cooling fans, which easily leads to too high temperature inside the distribution cabinet, affecting the normal operation of the equipment, shortening the service life, and even possibly causing potential safety hazards.

[0023] To solve the above-mentioned defects existing in the operation of the outdoor explosion-proof distribution cabinet, please refer to Figures 1-5 , a kind of outdoor explosion-proof distribution cabinet with heat dissipation function provided by the present utility model can, while exhausting the hot air inside the cabinet body 1, draw in the fresh air from the outside into the cabinet body 1, and convert the air into cold air and evenly blow it into the cabinet body 1, realizing the rapid cooling of the cabinet body 1, not only optimizing the ventilation effect inside the cabinet body 1, but also improving the heat dissipation efficiency of the equipment. The outdoor explosion-proof distribution cabinet device is based on the cabinet body 1. One side of the cabinet body 1 is provided with a ventilation pipe 2, the inside of the ventilation pipe 2 is provided with a dust-proof net 3, the outside of the dust-proof net 3 is rotatably installed with an exhaust fan 4, the other side of the cabinet body 1 is provided with a filter plate 5, the outside of the filter plate 5 is rotatably installed with an intake fan 6, and the top of the cabinet body 1 is provided with a driving mechanism 8 for driving the exhaust fan 4 and the intake fan 6 to rotate synchronously. Driving the driving mechanism 8 can drive the exhaust fan 4 and the intake fan 6 to rotate synchronously. The rotation of the exhaust fan 4 can extract the hot air inside the cabinet body 1 along the ventilation pipe 2, and the rotation of the intake fan 6 can convey the fresh air from the outside into the cabinet body 1, accelerating the air circulation and contributing to the heat dissipation of the cabinet body 1. The settings of the dust-proof net 3 and the filter plate 5 can prevent the outside dust and impurities from entering the cabinet body 1 and play a protective role for the electronic components inside the cabinet body 1.

[0024] When the intake fan 6 conveys the fresh air from the outside to the cabinet body 1, the outside air is at room temperature. Although the room-temperature air is lower than the original hot air temperature inside the cabinet body 1 and can play a preliminary heat dissipation effect on the cabinet body 1, the cooling effect on the cabinet body 1 is still not obvious enough. To solve this technical problem, a cooling mechanism 7 is provided inside the cabinet body 1, in which an air conditioner 71 fixedly installed outside the cabinet body 1 is provided. At least two air supply pipes 72 are arranged on the air conditioner 71. The air outlet of the air supply pipe 72 is arranged upward. The end of the air supply pipe 72 extends into the cabinet body 1. And two suspension rods 74 are symmetrically installed on the inner top wall of the cabinet body 1. An air distribution plate 75 corresponding to the intake fan 6 is slidably connected to the outside of the two suspension rods 74. The air distribution plate 75 is arranged as an arc plate, and a plurality of uniformly distributed diversion holes 76 are formed on the air distribution plate 75. The air conditioner 71 conveys cold air into the cabinet body 1 through the air supply pipe 72. When the cold air flows upward to the intake fan 6, the intake fan 6 can form cold wind and blow it into the cabinet body 1. The cold wind is dispersed by the air distribution plate 75 and flows into the cabinet body 1 along the diversion holes 76, playing a role in cooling the cabinet body 1. The distance between the upper end of the air distribution plate 75 and the inner wall of the cabinet body 1 is less than the distance between the lower end of the air distribution plate 75 and the inner wall of the cabinet body 1, so that the cold air can enter the air distribution plate 75 to the greatest extent and be fully blown out by the intake fan 6.

[0025] In order to make the cold wind be more evenly distributed in the cabinet body 1, an extension shaft 73 is fixedly connected to the center of the intake fan 6. The end of the extension shaft 73 extends into the cabinet body 1 and is fixedly connected to a driving rod 77. The end of the driving rod 77 is rotatably connected to a driven rod 78. The upper end of the driven rod 78 is rotatably connected to one side of the top of the air distribution plate 75. When the intake fan 6 rotates, it can drive the driving rod 77 to rotate. The driving rod 77 rotates and pulls the driven rod 78 to swing. The driven rod 78 swings to drive the air distribution plate 75 to slide up and down along the suspension rod 74. As the air distribution plate 75 continuously shakes, the cold wind can be blown more evenly into the cabinet body 1, expanding the coverage range of the cold wind and optimizing the cooling effect of the cooling mechanism 7.

[0026] Since the heat inside the cabinet body 1 needs to be discharged from the ventilation pipe 2, in order to accelerate the dispersion of heat, heat dissipation pipes 11 are symmetrically installed on the inner wall of the ventilation pipe 2. One end of the heat dissipation pipe 11 extends into the cabinet body 1, and the other end of the heat dissipation pipe 11 is sleeved with a plurality of heat dissipation fins 9. Part of the heat released from the ventilation pipe 2 can be discharged to the outside air, and part of the heat can be absorbed by the heat dissipation pipe 11 and transmitted to the heat dissipation fins 9. The heat dissipation fins 9 can assist the ventilation pipe 2 to release heat and improve the heat dissipation efficiency of the equipment.

[0027] Only relying on the heat dissipation pipe 11 to fix the multiple heat dissipation fins 9, the stability is poor. Therefore, an isolation frame 10 is installed on one side of the cabinet body 1 close to the exhaust fan 4, and the multiple heat dissipation fins 9 are fixedly installed on the isolation frame 10. On the one hand, the isolation frame 10 can enhance the stability of the heat dissipation fins 9, and on the other hand, it can lift the heat dissipation fins 9, so that there is a gap between the heat dissipation fins 9 and the cabinet body 1, improving air flow and making heat easier to be taken away.

[0028] In order to achieve the effect that the driving mechanism 8 drives the exhaust fan 4 and the intake fan 6 to rotate synchronously, the driving mechanism 8 is set as a servo motor 81 fixedly installed on one side of the top of the cabinet body 1. The output end of the servo motor 81 is fixedly connected with a connecting rod 82. The connecting rod 82 is rotatably installed on the top of the cabinet body 1, and pulley one 83 is fixedly sleeved at both ends of the connecting rod 82. Pulley two 84 is fixedly sleeved at the centers of the exhaust fan 4 and the intake fan 6. A synchronous belt 85 is commonly installed between the pulley one 83 and the pulley two 84 on the same side. Driving the servo motor 81 to drive the connecting rod 82 to rotate, the connecting rod 82 drives the two pulley ones 83 to rotate, the two pulley ones 83 drive the two pulley twos 84 to rotate through the synchronous belt 85, and the two pulley twos 84 drive the exhaust fan 4 and the intake fan 6 to rotate respectively, so as to realize the intake and exhaust of the cabinet body 1.

[0029] The control mode of the present utility model is automatically controlled by a controller. The control circuit of the controller can be realized by simple programming of those skilled in the art. The provision of power also belongs to the common knowledge in the art. And the present utility model is mainly used to protect mechanical devices, so the control mode and circuit connection of the present utility model will not be explained in detail.

[0030] It should be noted that in this article, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0031] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
