[0035] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Example 1

[0037] like Figures 1 to 11As shown, the present embodiment proposes a TVS diode packaging structure, including a packaging shell 4, the interior of the packaging shell 4 is provided with ventilation holes, and a plurality of arrays of equidistantly distributed heat dissipation grilles 5 are arranged on the ventilation holes, the packaging shell 4 is respectively provided with an inlet hole 7 and an outlet hole 6, the inlet hole 7 and the outlet hole 6 are symmetrically arranged, two symmetrically arranged mounting seats 9 are fixedly provided inside the packaging shell 4, and circulating water circuits are arranged inside the two mounting seats 9, a connecting seat 8 is fixedly provided inside the packaging shell 4, the connecting seat 8 is connected to the water outlet holes of the two circulating water circuits, the connecting seat 8 is fixedly connected to the water outlet hole, and the water outlet hole is connected to the outlet hole 6, and a quick disassembly and assembly mechanism 1 is fixedly provided on the two mounting seats 9, and the quick disassembly and assembly mechanism 1 includes two symmetrically arranged diode bodies 101, the bottoms of the two diode bodies 101 are fixedly connected with slide bars 102, and two symmetrically arranged slide grooves 104 are provided inside the mounting seat 9, and the slide grooves 104 have the same shape and size as the slide bars 102.

[0038] like Figures 1 to 11 As shown, the inside of the two slide bars 102 is provided with a telescopic groove 110, and the inside of the telescopic groove 110 is slidably connected with a fixed block 108, one end of the fixed block 108 is inclined, and the top of the fixed block 108 and the top wall of the telescopic groove 110 are connected with a first spring 107, and the inside of the two slide bars 102 is provided with an alignment hole 105 that passes through itself, and the alignment hole 105 has the same shape and size as the circulating water channel.

[0039] like Figures 1 to 11 As shown, a top block 112 is fixedly provided on the bottom wall of the slide groove 104, one end of the top block 112 is inclined, a straight groove 109 is opened inside the slide groove 104, a reset slider 106 is slidably connected inside the straight groove 109, one end of the reset slider 106 is inclined, one side of the reset slider 106 and the side wall of the straight groove 109 are connected with a second spring 111, and transparent display panels 103 are provided on both mounting seats 9.

[0040] In this embodiment, the packaging shell 4 is used to fix the TVS diode body 101 and play a protective role. Ventilation holes are symmetrically arranged on both sides of the packaging shell 4. A heat dissipation grille 5 is installed on one of the ventilation holes to ensure air circulation while reducing dust entry. The other ventilation hole is dedicated to the installation and removal of the TVS diode body 101. The packaging shell 4 is provided with an inlet hole 7 and an outlet hole 6 to form a closed circulating water system. The inlet hole 7 is used to connect an external water-cooling pipe to introduce the cooling liquid into the packaging shell 4. Two symmetrically arranged mounting seats 9 are fixedly arranged inside the packaging shell 4. The mounting seats 9 are designed with circulating water circuits inside. These water circuits are connected to the outlet holes 6 through the water outlet holes on the connecting seat 8 to form a closed cooling cycle. The design of the circulating water circuit ensures that the cooling liquid can flow through the TVS diode body 101 evenly and efficiently, thereby effectively reducing its operating temperature;

[0041] Furthermore, two symmetrically arranged mounting seats 9 are fixedly provided inside the packaging shell 4 for connecting the TVS diode body 101. A quick disassembly and assembly mechanism 1 is designed between the mounting seat 9 and the TVS diode body 101. During installation, it is only necessary to slide the two slide bars 102 at the bottom of the TVS diode body 101 into the slide groove 104 on the mounting seat 9 at the same time. The fixed card block 108 will contact the top block 112 on the bottom wall of the slide groove 104 during the movement, and shrink to the inside of the slide bar 102 under the action of the top block 112. When the fixed card block 108 moves to the straight groove 109 position inside the slide groove 104, the elastic force of the first spring 107 will push it downward, so that the vertical surface on one side of it abuts against the side wall of the straight groove 109 and one side of the top block 112, thereby realizing the limiting effect on the fixed card block 108 and ensuring the stable installation of the TVS diode body 101.

[0042] In addition, when disassembling, it is only necessary to push the TVS diode body 101 again along the axial direction of the slide slot 104, and the fixed block 108 will contact the reset slider 106 inside the straight slot 109. Under the action of the reset slider 106, the fixed block 108 will retract into the inside of the slide bar 102 again, and will not pop out again until it moves to the inclined surface on the other side of the reset slider 106. At this time, the vertical surface of the fixed block 108 abuts against the inclined surface of the reset slider 106, forming a temporary fixed structure. Then, it is only necessary to pull the TVS diode body 101 outward, and the fixed block 108 will push the reset slider 106 to move in the direction close to the top block 112 until one side of the reset slider 106 fits with one side of the top block 112. At this time, the top of the reset slider 106 and the top of the top block 112 are on the same axis, the reset slider 106 is fixed, and the fixed block 108 retracts upward to the inside of the slide bar 102 again under the thrust of the inclined surface of the reset slider 106. When the fixed block 108 is completely retracted into the slide bar 102, it fits with the top of the reset slider 106 and the top block 112 at the same time, and slides outward as the TVS diode body 101 is pulled out. At this time, the reset slider 106 will be reset to the initial position under the action of the second spring 111. It should be noted that the width of the reset slider 106 and the top of the top block 112 are calculated and tested to ensure that the bottom of the fixed block 108 is simultaneously placed on the top of the reset slider 106 and the top block 112, thereby ensuring the smooth disassembly of the TVS diode body 101;

[0043] In order to ensure the stable connection of the TVS diode body 101 in the packaging shell 4 and avoid shaking caused by the installation gap, a layer of polymer coating is coated on the side wall of the slide groove 104. This coating has good adhesion and friction, can fit closely to the side wall of the slide groove 104, and provide sufficient friction when the slide bar 102 contacts the slide groove 104. When the slide bar 102 slides into the slide groove 104, the coating on both sides achieves a stable connection effect, avoiding the slide bar 102 and the TVS diode body 101 from shaking up and down and sliding back and forth, thereby effectively reducing or eliminating the installation gap, improving the stability and reliability of the TVS diode packaging structure, thereby achieving the effect of front and rear limiting the TVS diode body 101 by the fixed block 108, and the polymer coating achieves a limiting effect on the up and down movement of the slide bar 102, ensuring a stable connection;

[0044] Furthermore, alignment holes 105 are provided inside the two slide bars 102, which penetrate through the two slide bars 102. These alignment holes 105 match the circulating water circuit inside the mounting seat 9. When the TVS diode body 101 is not mounted on the mounting seat 9, the two slide bars 102 are not inside the slide groove 104. At this time, the circulating water circuit is disconnected. When the two TVS diode bodies 101 are correctly mounted on the mounting seat 9, the two circulating water circuits will be linked together, and the cooling liquid can flow normally. At this time, the installer can observe whether the cooling liquid flows smoothly through the transparent display board 103, so as to judge whether the installation is correct. If the transparent display board 103 shows that the cooling liquid does not flow well, it means that the installation is incorrect and needs to be re-checked and adjusted.

[0045] The inlet hole 7 and the outlet hole 6 are connected to the external water-cooling pipe and the internal cooling water circuit respectively. The coolant is drawn from the coolant storage tank by a circulating pump and pumped to the inlet hole 7 of the packaging shell 4 through the pipeline system. Inside the packaging shell 4, the coolant flows through the circulating water circuits in two symmetrically arranged mounting seats 9. These water circuits evenly cover the TVS diode body 101 to ensure that the heat can be effectively absorbed. Subsequently, the heated coolant flows out through the water outlet holes on the mounting seat 9 and the outlet hole 6 of the packaging shell 4 to complete the preliminary heat exchange.

[0046] Example 2

[0047] like Figures 1 to 11As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that an emergency switching mechanism 2 is arranged inside the packaging shell 4, and the emergency switching mechanism 2 includes a connecting plate 201, and the connecting plate 201 is slidably arranged inside the packaging shell 4. Water inlet pipes are arranged on the two mounting seats 9, and the water inlet pipes are connected to the water inlet pipe of the circulating water circuit. A guide hole 209 that runs through the connecting plate 201 is opened inside, and the guide hole 209 has the same shape and size as the water inlet pipe. A survival frame 208 is fixedly arranged inside the packaging shell 4, and the survival frame 208 is communicated with the guide hole 209.

[0048] like Figures 1 to 11 As shown, a side rod 204 is fixedly provided on the connecting plate 201, and two symmetrically arranged fixing sleeves 202 are fixedly provided inside the encapsulating shell 4, a circular groove is provided inside the fixing sleeve 202, mercury is provided inside the circular groove, a telescopic top rod 203 is slidably connected inside the circular groove, and the top ends of the two telescopic top rods 203 are fixedly connected to the bottom of the side rod 204, a mounting groove is provided inside the encapsulating shell 4, an oblique clamping block 206 is slidably connected inside the mounting groove, one side of the oblique clamping block 206 is connected to the side wall of the mounting groove with a limiting spring 205, and a clamping groove 207 is provided inside the connecting plate 201, and the shape and size of the clamping groove 207 and the oblique clamping block 206 are the same.

[0049] In this embodiment, in view of the consequences of the TVS diode body 101 being suddenly damaged by high temperature generated under high load or long-term operation, resulting in system shutdown, an innovative emergency switching mechanism 2 is designed to ensure the continuity and stability of system operation. Two TVS diode bodies 101 are installed in the packaging shell 4, respectively located on two mounting seats 9. In the initial state, the lower TVS diode body 101 is powered on as the main device, and the upper TVS diode body 101 is used as a backup emergency device.

[0050] Specifically, when the TVS diode body 101 is under high load or works for a long time, a large amount of heat is generated, and the heat is quickly transferred to the inside of the packaging shell 4, and further transferred to the fixing sleeve 202 inside the mounting seat 9. The fixing sleeve 202 is made of copper-based alloy material to ensure that the heat can be quickly and effectively transferred to the mercury therein. As the mercury expands due to heat, it pushes the telescopic top rod 203 to move upward, and at the same time drives the connecting plate 201 and the side rod 204 thereon to rise together;

[0051] As the connection plate 201 rises, the guide hole 209 on it will gradually align with the water inlet hole of the upper mounting seat 9. When the connection plate 201 moves to the top, the guide hole 209 is completely connected with the water inlet hole, and the coolant in the survival frame 208 will flow into the upper connection plate 201 through the guide hole 209 to cool the spare TVS diode body 101. At the same time, the circuit will automatically switch to the spare TVS diode body 101 to ensure continuous and stable operation of the system.

[0052] In order to ensure that the connecting plate 201 can be stably maintained at a high position after moving, a limiting structure is further provided inside the packaging shell 4. When the connecting plate 201 moves upward, it will contact the inclined surface of the oblique clamping block 206, pushing the oblique clamping block 206 to retract into the storage groove. When the clamping groove 207 on the connecting plate 201 moves to one side of the oblique clamping block 206, the oblique clamping block 206 is quickly ejected under the action of the limiting spring 205 and firmly clamped into the clamping groove 207, thereby achieving the limiting effect on the connecting plate 201. This design effectively avoids the problem of resetting the connecting plate 201 due to temperature reduction.

[0053] It should be noted that the fixing sleeve 202 is made of a copper-based alloy material with high thermal conductivity. This material has good thermal conductivity and thermal stability. It can quickly and effectively transfer the heat inside the mounting seat 9 to the mercury in the fixing sleeve 202. As the mercury is heated, its volume will expand according to the principle of thermal expansion and contraction. After the mercury expands, it pushes the telescopic top rod 203 to move upward.

[0054] In addition, in order to ensure the stability of the circuit and the continuous operation of the system, when the main TVS diode body 101 reaches a preset temperature threshold due to overheating, the thermal sensing element will respond quickly and trigger the circuit switching through a mechanical or electronic switch. At this time, the power supply connected to the main TVS diode body 101 will be automatically disconnected, and the backup TVS diode body 101 will quickly connect to the circuit and take over the responsibility of transient voltage protection. The principle is similar to the dual power automatic switching circuit mechanism, which is a prior art and will not be repeated here.

[0055] Example 3

[0056] like Figures 1 to 11As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a protective heat dissipation mechanism 3 is provided on both mounting seats 9, and the protective heat dissipation mechanism 3 includes a heat-conducting metal plate 301 and a heat-conducting metal frame 302. The heat-conducting metal frame 302 is fixedly arranged on the top of the mounting seat 9, and a side support plate 303 is fixedly connected to the heat-conducting metal frame 302. A rotating rod 308 is rotatably installed on the side support plate 303. A gear 309 is rotatably sleeved on the outer peripheral surface of the rotating rod 308 through a one-way bearing. One side of the gear 309 and one side of the side support plate 303 are commonly connected with a torsion spring 310, and the torsion spring 310 is sleeved on the outside of the rotating rod 308.

[0057] like Figures 1 to 11 As shown, a connecting bracket 307 is fixedly provided on one side of the heat-conducting metal plate 301, and a first support rod 304 and a second support rod 306 are movably hinged on the connecting bracket 307, and the other end of the first support rod 304 is movably hinged to the side support plate 303, and another section of the fixing sleeve 202 of the second support rod 306 is arranged on the outer peripheral surface of the rotating rod 308, and a transmission rack 305 is fixedly provided on the diode body 101, and the transmission rack 305 is meshingly connected with the gear 309.

[0058] In this embodiment, in order to significantly improve the heat dissipation performance, a protective heat dissipation mechanism 3 is designed to assist the heat dissipation effect. When the TVS diode body 101 is installed, the fixed transmission rack 305 will precisely mesh with the gear 309, thereby driving the gear 309 to rotate. Since the gear 309 is connected to the rotating rod 308 through a one-way bearing, this special design ensures that the rotating rod 308 remains stationary when the gear 309 rotates. At this time, the torsion spring 310 connected between the spur gear 309 and the side support plate 303 begins to accumulate torque;

[0059] As the transmission rack 305 continues to move forward until it is separated from the gear 309, the installation of the TVS diode body 101 is completed. At this time, the torsion spring 310 is no longer stressed and begins to release the previously accumulated torque, pushing the gear 309 to rotate in the opposite direction and driving the rotating rod 308 to rotate synchronously. The rotation of the rotating rod 308 further drives the connecting bracket 307 and the second support rod 306 to rotate, thereby driving the fixedly connected heat-conducting metal plate 301 to flip. At the same time, the first support rod 304 also rotates accordingly, playing a role of balanced connection. The torque released by the torsion spring 310 just flips the heat-conducting metal plate 301 90 degrees, so that one side of it is tightly fitted to the side of the TVS diode body 101.

[0060] After the TVS diode body 101 is installed, the outer peripheral surface of the TVS diode body 101 is respectively bonded to the heat-conducting metal frame 302. The heat-conducting metal plate 301 and the heat-conducting metal frame 302 are both made of copper alloy materials with high thermal conductivity. These materials can effectively absorb and quickly conduct the heat generated by the TVS diode body 101, ensuring its stable and efficient operation, while improving the heat dissipation performance and reliability of the overall system;

[0061] During disassembly, flip the heat-conducting metal plate 301 upward 90 degrees by hand so that the heat-conducting metal plate 301 is flipped again to the top of the TVS diode body 101. It should be noted that during the disassembly process, after the fixed block 108 is separated from the top block 112, it is necessary to push it upward with force so that the transmission rack 305 and the gear 309 do not contact each other during the resetting process.

[0062] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
