Description

Technical Field

[0001] This utility model relates to the technical field of ship security alarm systems, and in particular to a heat dissipation device for a Beidou SSAS control box. Background Technology

[0002] The Beidou SSAS control box is a device used in ship security alarm systems. It primarily transmits ship security alarm information via the Beidou satellite system. The Beidou SSAS control box connects to a Beidou short message shipborne terminal on the deck. When an alarm or test button is triggered, the control box encodes and encapsulates the corresponding information, sending it to the Beidou satellite via the Beidou short message communication link. The Beidou satellite then forwards the information to the ground control center or a designated receiving terminal. Upon receiving the information, the ground control center or receiving terminal decodes and processes it to obtain relevant information such as the ship's location and alarm type.

[0003] In order to ensure the heat dissipation requirements of the Beidou SSAS control box during installation and use, heat sinks are usually installed on the back shell of the control box, combined with forced air cooling. However, this heat dissipation structure is relatively simple and its effect on guiding and dissipating heat inside the control box is not effective, which often makes the control box susceptible to high temperature damage. Therefore, we propose a heat dissipation device for Beidou SSAS control boxes. Utility Model Content

[0004] The main objective of this invention is to provide a heat dissipation device for a Beidou SSAS control box. By installing a heat dissipation mechanism on the control box body of the existing Beidou SSAS control box, the heat dissipation mechanism has air supply and guidance structures on the sides and back of the control box body. The heat dissipation mechanism adopts a multi-directional airflow guidance method. The internal guide fan sends air inward from the side recessed seat screen window, and the L-shaped lifting plate and grid groove accelerate the exhaust of hot air. The cooling fan draws air outward through the gradually lowering air guide cover, forming a through airflow, which greatly improves the heat guidance and exhaust efficiency of the control box body, reduces internal heat accumulation, and can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A heat dissipation device for a Beidou SSAS control box includes a control box body and a heat dissipation mechanism. The heat dissipation mechanism includes a side recessed seat, an internal fan, an outer support frame, a cooling fan, a grille, a matching frame, and a gradually lowering air guide shroud. The side recessed seat is recessed in the side wall of the control box body, and a screen window communicating with the control box body is opened at the bottom of the side recessed seat. An internal fan covering the screen window is installed in the seat of the side recessed seat. An outer support frame for installing the cooling fan is welded to the back box surface of the control box body near the side recessed seat, and a gradually lowering air guide shroud is installed on the back of the control box body on one side of the outer support frame. A back perforation groove is opened through the back shell wall of the control box body near the gradually lowering air guide shroud, and a grille is fitted and welded into the back perforation groove. A matching frame is installed in the back perforation groove outside the grille, and a dustproof net is fixed in the frame opening of the matching frame.

[0007] Furthermore, the surface of the grille plate is provided with grille grooves that communicate with the inner cavity of the control box body, and an L-shaped lifting plate that extends into the control box body to draw hot air outward is welded into the grille grooves away from the outward support frame grooves.

[0008] By adopting the above technical solution, after the grating plate is interconnected with the control box body through the grating groove, the L-shaped lifting plate at the grating groove of the grating plate can serve as a guiding structure. When the internal guide fan blows dust along the screen window of the side recess, the wind can blow the heat in the control box body to the L-shaped lifting plate along the screen window, assisting the heat in the control box body to be drawn out of the dustproof net.

[0009] Furthermore, an installation hole for screwing in an internal hexagon bolt is provided between the back through groove on the outer side of the grating plate and the frame plate of the frame, and an enlarged hole for hiding the head of the internal hexagon bolt is provided at the installation hole of the frame.

[0010] By adopting the above technical solution, the mounting holes of the frame and the back through groove can be screwed with hexagon socket bolts, and the head of the hexagon socket bolts can be hidden in the enlarged hole of the frame.

[0011] Furthermore, the large opening of the gradually lowering air guide hood rests against the outer support frame, and a small opening is provided on the side of the hood body away from the outer support frame. The hood body of the gradually lowering air guide hood is welded with perforated plates on both sides, and the perforated plates are locked to the control box body by bolts.

[0012] By adopting the above technical solution, after the cooling fan at the outer support frame blows air, the air force can be guided and gathered by the gradually lowering air guide shroud, so that the air force can efficiently remove the heat emitted from the dustproof net.

[0013] Furthermore, the cavity size of the side recess is larger than the housing size of the inner fan, and a mounting hole for screwing bolts is provided between the housing of the inner fan and the bottom of the side recess.

[0014] By adopting the above technical solution, the internal fan can be inserted into the seat cavity of the side recess and locked with bolts. Then, the internal fan can blow dust at the screen window of the side recess, so that the air can enter the control box body and guide the heat to be carried away.

[0015] Furthermore, the outer support frame has mounting holes on its frame plate surface away from its own frame holes, and bolts are screwed between the mounting holes of the outer support frame and the housing mounting holes of the cooling fan.

[0016] By adopting the above technical solution, the cooling fan can be locked to the outer support frame with bolts to supply air as needed.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This utility model incorporates a heat dissipation mechanism into the control box body of the existing Beidou SSAS control box. The heat dissipation mechanism features air supply and guidance structures on the sides and back of the control box body. The heat dissipation mechanism employs a multi-directional airflow guidance method, with an internal fan supplying air inward from the side recessed seat screen window. This, combined with an L-shaped lifting plate and grille groove, accelerates the exhaust of hot air. The cooling fan draws air outward through a gradually lowering air guide cover, forming a through airflow. This significantly improves the efficiency of heat guidance and exhaust at the control box body, reducing internal heat accumulation.

[0019] Furthermore, the heat dissipation mechanism features a gradually lowering air guide shroud to optimize the airflow path, achieving efficient heat dissipation within a limited space. The side recesses and frame of the heat dissipation mechanism are equipped with dustproof designs to reduce the amount of dust entering the control box body during heat dissipation.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1-4 As shown, a heat dissipation device for a Beidou SSAS control box includes a control box body 1 and a heat dissipation mechanism 2. The heat dissipation mechanism 2 includes a side recessed seat 3, an internal fan 5, an external support frame 6, a cooling fan 7, a grille 9, a frame 11, and a gradually lowering air guide shroud 13. The side recessed seat 3 is recessed in the side wall of the control box body 1, and a screen window 4 communicating with the control box body 1 is opened at the bottom of the side recessed seat 3. A shielding screen window 4 is installed inside the seat of the side recessed seat 3. An internal fan 5 is provided. The back box surface of the control box body 1 near the side recess 3 is welded with an outer support frame 6 for installing a cooling fan 7. A gradually lowering air guide shroud 13 is installed on the back of the control box body 1 on one side of the outer support frame 6. A back penetration groove 8 is provided through the back shell wall of the control box body 1 near the gradually lowering air guide shroud 13. A grille plate 9 is fitted and welded into the back penetration groove 8. A frame 11 is installed in the back penetration groove 8 outside the grille plate 9. A dustproof net 12 is fixed in the frame opening of the frame 11.

[0027] Among them, the surface of the grating plate 9 is provided with grating grooves that communicate with the inner cavity of the control box body 1, and an L-shaped lifting plate 10 that extends into the control box body 1 to draw hot air outward is welded into the groove of the outward support frame 6 away from the grating groove.

[0028] By adopting the above technical solution, after the grille plate 9 communicates with the control box body 1 through the grille groove, the L-shaped lifting plate 10 at the grille groove of the grille plate 9 can serve as a guiding structure. When the internal fan 5 blows dust along the screen window 4 of the side recess 3, the wind can blow the heat in the control box body 1 towards the L-shaped lifting plate 10 along the screen window 4, which helps to draw the heat in the control box body 1 outward to the dustproof net 12.

[0029] Among them, the back through groove 8 on the outer side of the grid plate 9 is provided with a mounting hole for screwing in the internal hexagon bolt between the frame plate of the frame 11 and the mounting hole of the frame 11 is provided with an enlarged hole for hiding the head of the internal hexagon bolt.

[0030] By adopting the above technical solution, the mounting holes of the frame 11 and the back through groove 8 can be screwed with hexagon socket bolts, and the head of the hexagon socket bolts can be hidden in the enlarged hole of the frame 11.

[0031] The large opening of the gradually lowering air guide hood 13 rests against the outer support frame 6, and a small opening is provided on the side of the hood body away from the outer support frame 6. The hood body of the gradually lowering air guide hood 13 is welded with perforated plates on both sides, and the perforated plates are locked to the control box body 1 by bolts.

[0032] By adopting the above technical solution, after the cooling fan 7 blows air at the outer support frame 6, the air force can be guided and gathered by the gradually lowering air guide shroud 13, so that the air force can efficiently remove the heat emitted from the dustproof net 12.

[0033] The cavity size of the side recess 3 is larger than the housing size of the inner air guide fan 5, and an installation hole for screwing bolts is provided between the housing of the inner air guide fan 5 and the bottom of the side recess 3.

[0034] By adopting the above technical solution, the internal fan 5 can be inserted into the seat cavity of the side recess 3 and locked with bolts. Then, the internal fan 5 can blow dust at the screen window 4 of the side recess 3, so that the air can enter the control box body 1 and guide the heat to be carried away.

[0035] The outer support frame 6 has mounting holes on its frame plate surface away from its own frame hole, and bolts are screwed between the mounting holes of the outer support frame 6 and the housing mounting holes of the cooling fan 7.

[0036] By adopting the above technical solution, the cooling fan 7 can be locked to the outer support frame 6 with bolts to supply air as needed.

[0037] It should be noted that this utility model is a heat dissipation device for a Beidou SSAS control box. After setting a heat dissipation mechanism 2 as a heat dissipation device on the control box body 1 of the existing Beidou SSAS control box, after slotting the side wall of the control box body 1 according to the size of the side recess 3, the side recess 3 can be welded to the pre-slotted area of ​​the control box body 1 for recessed installation. Then, the inner fan 5 can be inserted into the side recess 3 and locked with bolts. At the same time, after opening the back through groove 8 on the back of the control box body 1, the grille plate 9 can be welded. The back through groove 8 can reserve part of the cavity for mounting frame 11. Then, the mounting frame 11 can be locked in the back through groove 8 with bolts. Then, the surface hole plate of the gradually lowering air guide shroud 13 can be locked to the back of the control box body 1 with bolts. At the same time, after the outer support frame 6 is welded to the back of the control box body 1, the cooling fan 7 can be installed with bolts, so that the cooling fan 7 can blow air into the outer support frame 6 and the gradually lowering air guide shroud 13. The inner fan 5 and the cooling fan 7 can be connected to an external controllable power supply for power control as needed.

[0038] When heat is generated inside the control box body 1, the internal fan 5 can blow air through the screen window 4 of the side recess 3 to prevent dust, allowing the air to enter the control box body 1 and guide the heat away. When the hot air encounters the L-shaped lifting plate 10 at the grille plate 9, it can accelerate outward along the grille plate 9 and the dustproof net 12 and enter the gradually lowering air guide hood 13. At this time, the outer support frame 6 can blow the hot air outward from the gradually lowering air guide hood 13, and the gradually lowering air guide hood 13 can gather the air force to assist the air force in efficiently carrying away the heat inside the gradually lowering air guide hood 13, ensuring effective heat dissipation of the control box body 1. The special air-guiding structure of the internal fan 5, combined with the grille plate 9 and the L-shaped lifting plate 10, is superior to the heat dissipation structure of existing control boxes and has a better heat dissipation guiding effect.
