[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

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.

[0034] High-density power supplies are widely used in various scenarios due to their small size and high power. However, under long-term high-power use, heat will be generated inside the device. The accumulation of this heat inside the device will not only affect the service life of the device and the stability of the power output, but may also pose a fire risk in extreme environments, causing damage to surrounding equipment and resulting in huge property losses.

[0035] Therefore, this invention provides a high-efficiency, high-power-density power supply.

A temperature sensing device 205 is installed on the outside of the main body 102; a sliding plate 208 is slidably connected to one side of the inside of the protective box 1; a sealing plug 209 is fixedly connected to the side of the sliding plate 208 away from the power supply main body 102; the sealing plug 209 is used in conjunction with the vent 103; a power cord 2010 is installed in the middle of the sliding plate 208; the firing mechanism includes a locking tooth 3; the locking tooth 3 is located on the outside of 27; a toothed rotating cylinder 301 is rotatably connected to the inside of the protective box 1 near the servo motor 203; a fixed sliding groove 302 is fixedly connected to the inside of the protective box 1 near the toothed rotating cylinder 301; a rack 30 is slidably connected inside the fixed sliding groove 302. 3; The rack 303 meshes with the toothed rotating cylinder 301; A cutting head 304 is fixedly connected to the end of the rack 303; 305 is installed inside the protective box 1; 305 is made of polyethylene material, which will begin to melt when exposed to flame; The fan blade 207 rotates inside 305; The sealing mechanism includes a sliding cylinder 4; The sliding cylinder 4 is located on both sides inside the protective box 1; A flame-retardant partition 401 is slidably connected inside the sliding cylinder 4; A fixed shaft 404 is fixedly connected to the end of the sliding cylinder 4; A cutting groove 405 is opened on the outer side of the fixed shaft 404; A compression spring 402 is fixedly connected inside the sliding cylinder 4; One end of the compression spring 402 The flame-retardant partition 401 is connected to the flame-retardant partition 401; a tension band 403 is fixedly connected to the side of the flame-retardant partition 401 near the compression spring 402; the tension band 403 is used in conjunction with the cutting groove 405; the crushing mechanism includes an inclined block 5; the inclined block 5 is located inside the protective box 1; a buckle 501 is hinged to the outside of the inclined block 5; the buckle 501 is connected to one end of the rack 303; a crushing block 502 is provided on the top of the buckle 501; the buckle 501 limits the crushing block 502; the plugging and unplugging mechanism includes a contact spring guide groove 6; the contact spring guide groove 6 is located outside the power supply body 102; a slot 601 is fixedly connected to the end of the power cord 2010.The slot 601 slides inside the contact spring guide groove 6. The groove inside the contact spring guide groove 6 increases the contact area between the slot 601 and the contact spring guide groove 6. Through multi-point contact, the contact resistance is reduced, and the heat generation effect is reduced. At the same time, during the insertion and removal process, the friction between the contact spring guide groove 6 and the slot 601 can scrape off the oxide film on the metal surface and maintain a low-resistance connection. The induction fire extinguishing assembly includes a sand box 7. The top of the sand box 7 has a sand inlet 701. A sealing block 702 is installed inside the sand inlet 701. Two sets of carbon dioxide high-pressure gas cylinders 703 are fixed to the bottom inside the sand box 7. Liquid carbon dioxide is injected into the carbon dioxide high-pressure gas cylinders 703. A nozzle 704 is fixedly connected to the end of a high-pressure carbon dioxide cylinder 703; then the nozzle 704 is aligned with the power supply body 102, and a pull plate 705 is installed at the end of the nozzle 704; a pull rope 706 is fixedly connected to the end of the pull plate 705; the end of the pull rope 706 is connected to 305; the burial mechanism includes a connecting pipe 8; an inflatable air cushion 801 is fixedly connected to the end of the connecting pipe 8; the inflatable air cushion 801 is located inside the sand box 7. The inflatable air cushion 801 is connected to the high-pressure carbon dioxide cylinder 703 through the connecting pipe 8. The liquid carbon dioxide inside the high-pressure carbon dioxide cylinder 703 will vaporize and fill the interior of the inflatable air cushion 801, keeping it taut and sealing the bottom of the sand box 7.

[0039] During operation, the power supply unit 102 is first installed on top of the mounting slot 101 inside the protective box 1. Then, the sand box 7 is placed on top of the protective box 1. The sand box 7 is then opened using the sealing block 702, and sand is poured into the sand box 7 through the sand inlet 701. The sand is blocked by the inflatable air cushion 801 and remains stationary inside the sand box 7. At this point, the sealing block 702 is closed to seal the sand inlet 701. Then, the power cord 2010 is connected to the slot 601, and the sliding plate 208 is pushed towards the contact spring guide groove 6 through the slot 601. Electrical connection is achieved between the power cord 2010 and the power supply body 102. A flame-retardant partition 401 separates the sliding plate 208 from the power supply body 102. The sealing plug 209 is positioned away from the vent 103, allowing for airflow and heat exchange within the protective enclosure 1. When the power supply body 102 starts operating, the cooling pump 2 is activated, pumping coolant into the heat sink 201. The heat sink 201 then connects to the heat-conducting block 202 and the mounting groove 101, enabling rapid flow of coolant within the heat sink 201. The power supply unit 102 is cooled and dissipated by carrying away the heat generated during operation. When the heat inside the power supply unit 102 is dissipated through the heat pipe 201, and the temperature continues to rise due to continued high-power operation, the signal receiving module 204 and temperature sensing device 205 detect the temperature. When the temperature of the power supply unit 102 exceeds the set threshold, the signal receiving module 204 drives the servo motor 203 to start working, causing the telescopic rod 206 and fan blades 207 to rotate, generating airflow and dissipating heat. Heat pipes 201 work together to achieve more efficient heat dissipation. When the main power supply 102 experiences thermal runaway and fire due to long-term high-power operation, 305 will begin to melt. After 305 melts, the telescopic rod 206 will retract, causing the locking teeth 3 to lock inside the toothed rotating cylinder 301. At the same time, the fan blade 207 continues to rotate, causing the rack 303 to slide on the top of the fixed slide groove 302, causing the cutting head 304 to impact the fixed shaft 404. Through the cooperation between the cutting head 304 and the cutting groove 405, the tension band 403 breaks.At this moment, the taut compression spring 402 quickly returns to its original position, pushing the flame-retardant partition 401 to slide inside the sliding cylinder 4. The impact force pushes the sliding plate 208, causing the slot 601 to disengage from the power supply body 102, thus cutting off the power to the power supply body 102. Simultaneously, when the sliding plate 208 is pushed, the sealing plug 209 engages inside the vent hole 103, sealing the vent hole 103 to isolate internal oxygen. When the rack 303 strikes the fixed shaft 404, the other end of the rack 303 pulls the buckle 501 on the outside of the inclined block 5, causing the buckle 501 to disengage from the limiting position of the broken block 502. The broken block 502 will then... Due to gravity, the liquid falls into the protective box 1, breaking the heat dissipation pipe 201. At this time, the cooling pump 2 will continue to work, spraying the coolant inside the heat dissipation pipe 201 into the protective box 1, which plays a certain role in extinguishing the fire. When 305 melts, 305 pulls the pull rope 706 and the pull plate 705, releasing the seal on the nozzle 704. At this time, the liquid carbon dioxide inside the high-pressure carbon dioxide cylinder 703 is sprayed into the protective box 1 to extinguish the fire. At the same time, the carbon dioxide absorbs a lot of heat during the vaporization process, further reducing the temperature inside the protective box 1. After the carbon dioxide spraying is completed, the air cushion 801 begins to decrease in pressure due to the lack of gas support. At this time, the sand inside the sand box 7 falls into the protective box 1, burying the power supply unit 102. Carbon dioxide cooling seals the vent 103, forming a sealed space. The cooling pipe 201 is broken, spraying out the coolant inside for auxiliary fire suppression. After the fire is extinguished, sand is used to bury the fire site, further isolating oxygen and absorbing heat. Through the use of multi-stage heat dissipation components and induction fire suppression components, the power supply unit 102, during operation at low power, only needs to... The cooling pump 2 and the heat pipe 201 work together to achieve cooling. When high power is used, if the temperature exceeds the set threshold, the servo motor 203 will be driven to start cooling, so that air cooling and water cooling work together to greatly improve the heat dissipation efficiency and increase the service life of the device. In the event of a fire in extreme circumstances, the fire extinguishing component will be activated to destructively drive the internal device. The purpose is to deal with the open flame as soon as possible, and to seal and reduce the internal structure of the device, preventing external oxygen from entering the protective box 1. This greatly reduces the possibility of the fire spreading and causing other damage when a fire occurs.

[0040] For details, see Figure 4-5 As shown, the fan blade 207 has multiple sets of breaking grooves 9 on its outer side; the heat-conducting block 202 is filled with paraffin wax, which can absorb heat and liquefy. It can absorb a large amount of heat in a short time without significant temperature rise. Before the paraffin wax completely melts, its temperature is basically constant, which has an auxiliary and enhancing effect on the heat dissipation of the power supply body 102.

[0041] When the fan blade 207 is working, it generates wind power by rotating continuously. The rotation of the fan blade 207 will generate eddies. These eddies will generate high-frequency noise and vibration. This noise and vibration will affect the surrounding environment and human ears. Therefore, the eddies generated by the breaking groove 9 are used to break the noise, so that the noise spectrum is shifted to the high-frequency band that is not sensitive to human ears, thereby reducing the impact of noise on human ears.
