Description

Technical Field

[0001] This invention relates to the field of explosion-proof technology, and more particularly to an explosion-proof box. Background Technology

[0002] Existing distribution boxes have a certain degree of enclosure. Generally, they achieve cooling by creating vents in the enclosure and adding fans inside to promote air circulation. However, in places with high levels of dust and hazardous gases in the outside air, dust and hazardous gases can enter the enclosure through the vents. If a spark occurs inside the distribution box, an explosion may occur. Therefore, to prevent dust and hazardous gases from entering the enclosure, the inside of the enclosure is sealed. However, sealing the enclosure leads to poor heat dissipation, causing the components installed inside the enclosure to operate at excessively high temperatures, thus affecting their service life. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing an explosion-proof box.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An explosion-proof enclosure includes a enclosure body, a heat dissipation box connected to one side of the enclosure body, a partition connected inside the heat dissipation box, the partition dividing the heat dissipation box into an upper cavity and a lower cavity, a coolant filling the upper cavity, a water pump connected to the lower cavity, the water pump being connected to the upper cavity via an inlet pipe, a cooling pipe being connected to the enclosure body via an outlet pipe, the cooling pipe being connected to the upper cavity body, a mobile heat dissipation device connected inside the enclosure body, a circulating air pump connected to the upper cavity body, the circulating air pump being connected to the mobile heat dissipation device via an outlet pipe, and the circulating air pump being connected to the enclosure body via an inlet pipe.

[0005] Preferably, the mobile heat dissipation device includes an air outlet box, a set of first air outlet holes evenly distributed on the air outlet box, an air outlet pipe with closed ends rotatably connected inside the air outlet box, a set of second air outlet holes evenly distributed spirally on the air outlet pipe, and when the air outlet pipe rotates, the set of second air outlet holes are correspondingly arranged with the set of first air outlet holes, and an air jet component slides up and down on the air outlet box.

[0006] Preferably, the jet component includes a U-shaped plate, which is sleeved on the outside of the air outlet box. A rectangular tube is connected to one side of the U-shaped plate, and a set of jet pipes are evenly distributed on the rectangular tube. A through hole is provided on the inner side of the U-shaped plate, and the through hole communicates with the rectangular tube.

[0007] Preferably, the mobile heat dissipation device further includes a drive motor connected to the upper side of the housing, the output shaft of the drive motor being connected to a screw, the screw thread driving a moving plate, the moving plate being connected to the rectangular tube, and the drive motor driving the air outlet pipe through a transmission mechanism.

[0008] Preferably, the transmission mechanism includes a first gear connected to the output shaft of the drive motor, the first gear meshing with a second gear, the second gear connected to a rotating shaft, the rotating shaft rotatably connected to a fixed plate, the fixed plate connected to the inner side of the housing, a drive wheel also connected to the rotating shaft, the drive wheel driving a driven wheel through a transmission belt, and the driven wheel connected to the air outlet pipe.

[0009] Preferably, guide strips are connected to both sides of the air outlet box, and guide grooves are provided on both sides of the U-shaped plate, with the guide strips slidably connected in the guide grooves.

[0010] Preferably, the portion of the air outlet duct that is inside the coolant has a serpentine structure.

[0011] Preferably, a set of heat-conducting boxes are inserted into one side wall of the heat sink, with one end of the heat-conducting box facing outward and the other end extending into the coolant. Each heat-conducting box has an opening on one side facing outward.

[0012] Preferably, a cooling fan is connected to the outside of the heat sink, and the airflow of the cooling fan is directed toward the opening of the heat conduction box.

[0013] The advantages of this invention are as follows: The explosion-proof box provided by this invention uses a water pump to draw coolant from the upper cavity into a cooling pipe, thereby cooling the air inside the box. In addition, a gas pump draws hot air from inside the box into an air outlet pipe, which is located in the coolant. The coolant cools the hot air in the air outlet pipe. The cooled air enters a mobile heat dissipation device, which then provides targeted heat dissipation to the electrical components inside the box, thereby effectively improving the heat dissipation efficiency inside the box. In addition, by blowing heat through the heat conduction box with a cooling fan, heat is dissipated from the heat conduction box, and then the coolant is cooled through the heat conduction box, so that the coolant can better dissipate heat from the cabinet.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on this invention.

[0017] like Figure 1 As shown, the present invention provides an explosion-proof box, including a box body 1, a heat dissipation box 2 connected to one side of the box body 1, and a partition 3 connected inside the heat dissipation box 2. The partition 3 divides the heat dissipation box 2 into an upper cavity and a lower cavity. The upper cavity is filled with coolant. In this embodiment, the coolant is cold water, and the height of the coolant is not higher than the height of the outlet of the cooling pipe 7 below.

[0018] A water pump 4 is bolted to the lower cavity. The water pump 4 is connected to the upper cavity via an inlet pipe 5 and an outlet pipe 6. The cooling pipe 7 is connected inside the housing 1, with its outlet connected to the upper cavity. The water pump 4 draws coolant from the upper cavity into the cooling pipe 7, which then returns to the upper cavity, forming a water circulation. The cooling pipe 7 cools the interior of the housing 1. The portion of the cooling pipe 7 inside the housing 1 has a serpentine structure, resulting in a larger contact area with the hot air inside the housing 1 and better heat dissipation. Furthermore, the electrical components and the cooling pipe 7 are integrated seamlessly. Figure 1 The arrangement shown can better absorb the heat emitted by electrical components.

[0019] A set of heat-conducting boxes 2.1 are inserted into one side wall of the heat sink 2. That is, a set of mounting slots are provided on the side wall of the heat sink 2, and a heat-conducting box 2.1 is welded into each mounting slot. The heat-conducting box 2.1 is made of copper, which has good thermal conductivity. One end of the heat-conducting box 2.1 is on the outside, and the other end extends into the coolant. Each heat-conducting box 2.1 has an opening on one side, which faces outward. Heat exchange with the coolant through the heat-conducting boxes 2.1 to cool the coolant. A cooling fan 2.2 is connected to the outside of the heat sink 2. The cooling fan 2.2 blows air towards the opening of the heat-conducting box 2.1, which accelerates the heat dissipation of the heat-conducting box 2.1, thereby cooling the coolant and enabling the coolant to better cool the casing 1.

[0020] Connect a mobile heat dissipation device 8 inside the housing 1, such as... Figure 2As shown, the mobile heat dissipation device 8 includes an air outlet box 8.1, which is connected inside the housing 1. The air outlet box 8.1 is a rectangular box with a cylindrical cavity inside. A set of first air outlet holes 8.8 are evenly distributed on the air outlet box 8.1. In this embodiment, there are four first air outlet holes 8.8 arranged vertically. An air outlet pipe 8.2 with closed ends is rotatably connected inside the air outlet box 8.1. A set of second air outlet holes 8.3 are evenly distributed spirally on the air outlet pipe 8.2. The number of second air outlet holes 8.3 corresponds to the number of first air outlet holes 8.8, which is also four. When the air outlet pipe 8.2 rotates, the four second air outlet holes 8.3 are positioned correspondingly to the four first air outlet holes 8.8. An air jet component 8.4 slides up and down on the air outlet box 8.1.

[0021] The jet component 8.4 includes a U-shaped plate 8.41, which is sleeved on the outside of the air outlet box 8.1. Guide strips 8.11 are connected to both sides of the air outlet box 8.1. Guide grooves 8.44 are provided on both sides inside the U-shaped plate 8.41. The guide strips 8.11 are slidably connected in the guide grooves 8.44. When the U-shaped plate 8.41 moves up and down on the air outlet box 8.1, the guide strips 8.11 slide within the guide grooves 8.44, making the U-shaped plate 8.41 more stable when moving.

[0022] A rectangular tube 8.42 is connected to one side of the U-shaped plate 8.41. A set of jet pipes 8.43 are evenly distributed on the rectangular tube 8.42. A through hole is provided on the inner side of the U-shaped plate 8.41, and the through hole connects to the rectangular tube 8.42.

[0023] The mobile cooling device 8 also includes a drive motor 8.5, which is connected to the upper side of the housing 1. The housing 1 has a through hole through which the output shaft of the drive motor 8.5 passes. The output shaft of the drive motor 8.5 is connected to a screw 8.6, which drives a moving plate 8.7 via a threaded connection. The moving plate 8.7 is connected to a rectangular tube 8.42. The drive motor 8.5 drives the screw 8.6 to rotate, and the screw 8.6 drives the moving plate 8.7 via a threaded connection. The moving plate 8.7 drives the rectangular tube 8.42 and the air jet pipe 8.43 to move up and down. The drive motor 8.5 also drives the air outlet pipe 8.2 via a transmission mechanism.

[0024] The transmission mechanism includes a first gear 12, which is connected to the output shaft of the drive motor 8.5. The first gear 12 meshes with a second gear 13, which is connected to a rotating shaft. The rotating shaft is rotatably connected to a fixed plate 14, which is connected to the inner side of the housing 1. A drive wheel 15 is also connected to the rotating shaft. The drive wheel 15 drives a driven wheel 17 via a transmission belt 16. The driven wheel 17 is connected to the air outlet pipe 8.2. In addition, the diameter of the first gear 12 is smaller than the diameter of the second gear 13, so that the vertical movement distance of the jet 8.4 corresponds to the rotation distance of the air outlet pipe 8.2, and the corresponding first air outlet 8.8 and second air outlet 8.3 correspond to the through hole. This allows all the cold air in the air outlet box 8.1 to enter the jet 8.4, and then the jet 8.4 provides targeted airflow and heat dissipation to the corresponding electrical components in the housing 1.

[0025] A circulating air pump 9 is connected to the upper cavity. The circulating air pump 9 is connected to the air outlet box 8.1 through the air outlet pipe 10. The part of the air outlet pipe 10 that is in the coolant has a serpentine structure. The circulating air pump 9 is connected to the housing 1 through the air inlet pipe 11. The circulating air pump 9 draws hot air from the housing 1 through the air inlet pipe 11, and then cools it down through the coolant before delivering it into the air outlet box 8.1. It is then ejected through the jet nozzle 8.4 to provide targeted heat dissipation for the electrical components.

[0026] This explosion-proof cabinet uses a water pump 4 to draw coolant from the upper cavity into the cooling pipe 7, thereby cooling the air inside the cabinet 1. In addition, an air pump 9 draws hot air from the cabinet 1 into the air outlet pipe 10, which is located in the coolant. The coolant cools the hot air in the air outlet pipe 10. The cooled air then enters the mobile heat dissipation device 8, which provides targeted heat dissipation for the electrical components inside the cabinet 1, preventing local electrical components from overheating. In addition, the cooling fan 2.2 blows heat to the heat conduction box 2.1 to dissipate heat, and then the heat conduction box 2.1 exchanges heat with the coolant, thereby cooling the coolant and enabling the coolant to better dissipate heat to the inside of the box 1.
