Abstract
Description
Technical Field
[0001] This utility model relates to the field of diode technology, specifically to a high-temperature resistant, high-safety, high-power diode. Background Technology
[0002] Diodes are among the earliest semiconductor devices, and they are mainly used in various electronic circuits. By connecting diodes with components such as resistors, capacitors, and inductors in a reasonable manner, circuits with different functions can be constructed, which can realize multiple functions such as AC rectification, modulation signal detection, amplitude limiting and clamping, and power supply voltage regulation.
[0003] Therefore, Chinese Patent Publication No. CN 215069950 U proposes a high-temperature resistant diode, relating to the field of diode technology. This addresses the problem that existing diodes, while being heat-generating elements, generate relatively little heat that doesn't affect their internal structure, but when applied to high-temperature environments, the external ambient temperature can cause them to burn out. The sealed housing contains a vacuum isolation cavity, inside which is a glass crystal tube. Ceramic pistons are located at both ends of the vacuum isolation cavity and are fitted to the glass crystal tube. An asbestos gasket is located on the outside of the vacuum isolation cavity and is fitted to the sealed housing. A metal lead is located inside the glass crystal tube and extends into the ceramic piston. One end of the sealed housing has a positive terminal, and the other end has a negative terminal.
[0004] However, when using this type of high-temperature resistant diode, the probability of temperature rise cannot be completely eliminated by adding heat insulation materials alone. When the equipment temperature rises during operation, it will still cause the diode to be damaged, shortening its service life and requiring frequent replacement, which wastes resources and results in defects in the use of the device.

[0017] This invention provides a high-temperature resistant, high-safety, high-power diode. Compared with the prior art, it has the following advantages:
[0018] 1. This high-temperature resistant, high-safety, high-power diode achieves rapid cooling of the diode body by incorporating a first protective shell, a second protective shell, a heat sink, a filter box, a cold air box, a water tank, a first mounting box, a second vent, a second filter plate, a fan, a cooling pipe, a first connection port, a second mounting box, a cooler, connecting pipes, and a water pump.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figure 1-7This utility model provides a technical solution: a high-temperature resistant, high-safety, high-power diode, comprising a first protective shell 1 and a second protective shell 2. The bottom of the first protective shell 1 is detachably connected to the second protective shell 2. Both the first and second protective shells 1 and 2 have multiple heat sinks 4 inside. One end of each heat sink 4 is in contact with the diode body 3, enabling rapid and effective heat dissipation from the diode body 3 to the air. The diode body 3 is detachably connected between the first and second protective shells 1 and 2. In the event of a failure in the diode body 3, the heat sinks can quickly and effectively dissipate heat from the first and second protective shells 1 and 2. The outer casing 2 is removed from the outside of the diode body 3 for inspection. A first mounting box 9 is fixedly connected to the top of the first protective casing 1. A second ventilation opening 6 is provided between the top of the first protective casing 1 and the first mounting box 9, allowing internal communication between the first protective casing 1 and the first mounting box 9. A fan 10 is installed inside the first mounting box 9. When the fan 10 is turned on, it blows the gas inside the first mounting box 9 into the first protective casing 1 and the second protective casing 2, allowing air circulation outside the diode body 3. A cold air box 11 is fixedly connected to one side of the first mounting box 9. A cooling pipe 14, filled with coolant, is fixedly connected internally to the gas chamber 11 to cool the gas inside. A water tank 12, filled with coolant, is fixedly connected to the side of the gas chamber 11 away from the first mounting box 9. A second mounting box 22, filled with coolant, is fixedly connected inside the water tank 12. A cooler 16 is fixedly connected inside the second mounting box 22 via a connecting plate. One end of the cooling pipe 14 passes through one side of the second mounting box 22 and is fixedly connected to the cooler 16. A water pump 18 is fixedly connected to one side of the cooler 16 via a connecting pipe 17. One end of the water pump 18 passes through the second mounting box 22. One side extends to the bottom of the interior of the water tank 12. The water pump 18 is turned on to draw coolant from the second mounting box 22. The coolant drawn by the water pump 18 enters the cooler 16 through the connecting pipe 17. The cooler 16 cools the coolant. The cooled coolant enters the cooling pipe 14, so that the temperature of the coolant in the cooling pipe 14 is kept within a certain range. The end of the cooling pipe 14 away from the cooler 16 passes through the side of the water tank 12 and extends into the interior of the water tank 12. The coolant in the cooling pipe 14 returns to the water tank 12 and is drawn by the water pump 18 into the cooler 16 for cooling.
[0030] Furthermore, L-shaped plates 21 are fixedly connected to both sides of the first protective shell 1 and the second protective shell 2. A locking block 23 is slidably connected inside the L-shaped plate 21. A locking hole 24 is opened on the side of the L-shaped plate 21 away from the locking block 23. The locking block 23 enters into the locking hole 24 to connect the first protective shell 1 and the second protective shell 2 together.
[0031] Furthermore, a first connection port 15 is provided between one side of the cold air box 11 and the first mounting box 9, allowing the cold air inside the cold air box 11 to enter the first mounting box 9.
[0032] Furthermore, the cold air box 11 has symmetrical second connection ports 19 on both sides. A filter box 13 is symmetrically fixedly connected to one side of the cold air box 11 and outside the second connection port 19. A third filter plate 20 is provided on the outside of the filter box 13. The third filter plate 20 filters the gas to be entered into the filter box 13 to prevent dust and impurities from entering the filter box 13. The gas in the filter box 13 enters the cold air box 11 through the second connection port 19.
[0033] Furthermore, a spring 25 is fixedly connected between one end of the locking block 23 and the L-shaped plate 21, and a movable plate 26 is fixedly connected to one side of the locking block 23. The movable plate 26 moves the locking block 23 toward the spring 25. The spring 25 is compressed and generates elastic force. When the spring 25 loses its pressing force, it returns to its original position with the locking block 23 under the action of the elastic force.
[0034] Furthermore, a limiting frame 27 is rotatably connected to one side of the L-shaped plate 21. A magnet 28 is provided on one side of the limiting frame 27, and an iron block 29 is provided on one side of the L-shaped plate 21. The limiting frame 27 rotates, causing the magnet 28 to rotate as well. When the limiting frame 27 moves with the magnet 28 to one side of the L-shaped plate 21, the movable plate 26 is located inside the L-shaped plate 21. With the cooperation of the magnet 28 and the iron block 29, the movable plate 26 is fixed to the outside of the movable plate 26, which limits the range of movement of the movable plate 26 and prevents the movable plate 26 from moving during use, causing the first protective shell 1 and the second protective shell 2 to become loose.
[0035] Furthermore, a second filter plate 8 is provided inside the second vent 6 to filter and dry the gas entering the second vent 6.
[0036] Furthermore, the bottom of the second protective shell 2 is provided with a first ventilation port 5, and the interior of the first ventilation port 5 is provided with a first filter plate 7 to filter the gas leaving the first protective shell 1 and the second protective shell 2, and also to prevent external dust and impurities from entering the first protective shell 1 and the second protective shell 2 through the first ventilation port 5.
[0037] Furthermore, ceramic pistons 31 are symmetrically arranged at both ends inside the diode body 3. There are two sets of ceramic pistons 31, which serve as insulation and protection. A glass crystal tube 30 is arranged between the two sets of ceramic pistons 31. The glass crystal tube 30 cooperates with the metal leads inside the diode body 3 to conduct current. A vacuum isolation cavity 33 is arranged inside the diode body 3 and between the two sets of ceramic pistons 31. The vacuum isolation cavity 33 can isolate the heat of the external environment from the inside of the crystal tube, and can also prevent current conduction, thereby improving the safety and heat resistance of the diode body 3. An asbestos gasket 32 is arranged inside the diode body 3 and outside the ceramic pistons 31. The asbestos gasket 32 can effectively block the transfer of heat.
[0038] In use, the ceramic piston 31 provides insulation and protection. The glass crystal tube 30, in conjunction with the metal leads inside the diode body 3, allows for current conduction. The vacuum isolation cavity 33 isolates the external heat from the crystal tube's interior while also preventing current conduction, thus improving the safety and heat resistance of the diode body 3. The asbestos gasket 32 effectively blocks heat transfer. The cooler 16 and water pump 18 are activated. The water pump 18 draws coolant from the water tank 12, and the drawn coolant enters the connecting pipe 17. The connecting pipe 17 then cools the... The coolant is used for cooling treatment. The cooled coolant enters the cooling pipe 14. The cooling pipe 14 is S-shaped, which prolongs the residence time of the coolant in the cooling pipe 14 to cool the gas in the cold air box 11. The fan 10 is turned on, and the fan 10 draws the cooled gas in the cold air box 11 into the first mounting box 9 through the first connection port 15. At this time, the outside gas passes through the third filter plate 20 on the outside of the filter box 13 and enters the second connection port 19, and then enters the cold air box 11 from the second connection port 19. The cooled gas in the first mounting box 9 passes through the second filter plate. After drying and filtration, the 8-phase gas enters the first protective shell 1 and the second protective shell 2 to cool the diode body 3. The heat generated by the diode body 3 is conducted through the heat sink 4, making the heat emitted by the diode body 3 more effectively conducted to the heat sink 4, and then dissipated into the surrounding air through the heat sink 4, improving the cooling efficiency of the diode body 3 and enabling rapid heat dissipation. The original gas inside the first protective shell 1 and the second protective shell 2 is filtered by the first filter plate 7 and discharged to the outside through the first vent 5, allowing the gas inside the first protective shell 1 and the second protective shell 2 to circulate and carry away the heat generated by the diode body 3. When the diode body 3 malfunctions, the limiting frame 27 can be rotated to move the limiting frame 27 away from one side of the moving plate 26, releasing the restriction on the moving plate 26. The moving plate 26, along with the locking block 23, leaves the locking hole 24, releasing the connection between the first protective shell 1 and the second protective shell 2, and removing the first protective shell 1 and the second protective shell 2 from the outside of the diode body 3, making it convenient for staff to inspect or replace the diode body 3.
