Description

Technical Field

[0001] This invention relates to the field of switchgear technology, specifically to a switchgear with a dual safety protection structure. Background Technology

[0002] Switchgear is a core set of electrical equipment in a power system used for power distribution, circuit control, and equipment protection. It assembles primary components such as circuit breakers, disconnectors, and instrument transformers into a metal cabinet according to a predetermined wiring scheme, realizing the functions of power reception, power supply, and fault protection. The components inside the cabinet can be divided into two main categories based on their heating characteristics: Category I electrical components, such as circuit breakers, disconnectors, current transformers, voltage transformers, and transformers, which carry large currents or have electromagnetic losses, belong to Category I electrical components. Their contact resistance or iron core coil losses will generate Joule heat or iron and copper losses during operation, leading to a significant temperature rise. Secondary circuit components such as instruments, relays, and temperature and humidity controllers, due to their extremely small operating current and low power consumption, generate almost no perceptible temperature rise during long-term operation and belong to Category II electrical components.

[0003] Current switchgear utilizes ventilation openings on the top surface, heat dissipation windows on the sides, and heat dissipation holes on the bottom, along with a cooling fan and heat dissipation cavity at the bottom of the cabinet, to ventilate and cool the first and second types of electrical components inside. However, in actual use, changes in external temperature can cause various problems: when the external environment is cold, the first type of electrical components continuously generate heat, while the second type of electrical components are prone to moisture and condensation at low temperatures, leading to electronic device failure. The existing structure cannot actively transfer the heat from the first type of electrical components to the second type for utilization. When the external environment is hot, the first type of electrical components generate even more heat due to the cumulative effect of the ambient temperature, and the second type of electrical components also heat up. Relying solely on heat dissipation holes and fans for cooling is limited in capacity and ineffective, making it difficult to cool down quickly. Furthermore, the high-temperature heat is not effectively utilized, resulting in energy waste, and the equipment is prone to damage due to overheating. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: a switch cabinet with a dual safety protection structure, comprising: Cabinet; Both the first type of electrical component and the second type of electrical component are located inside the cabinet. The first type of electrical component generates more heat than the second type of electrical component during operation. The adjustment mechanism includes an adjustment component and a working component disposed inside the cabinet. When the temperature is lower than a first preset temperature, the adjustment component adjusts the position of the working component to a first working position, so that the heat of the first type of electrical components is transferred to the second type of electrical components. When the temperature is higher than a second preset temperature, the adjustment component adjusts the position of the working component to a second working position, so that the working component dissipates heat from the first type of electrical components and the second type of electrical components respectively, and generates electricity through temperature difference. When the temperature inside the cabinet is abnormal, the power generation reaches a threshold, and the working component enhances the heat dissipation of the second type of electrical components and the first type of electrical components.

[0005] Preferably, the inner wall of the cabinet is provided with a partition, and the adjustment mechanism further includes two heat-conducting blocks. The two heat-conducting blocks are both disposed on the partition and connected to the first type of electrical component and the second type of electrical component respectively through multiple heat-conducting wires.

[0006] Preferably, the adjustment component includes a housing disposed on the inner wall of the cabinet, a temperature sensing component disposed inside the housing, a push plate that slides inside the housing at one end of the temperature sensing component, a push rod that penetrates the housing at the end of the push plate away from the temperature sensing component, a connecting plate at the end of the push rod away from the push plate, a spring at the end of the connecting plate away from the push rod, and the other end of the spring being disposed on the inner wall of the housing, the spring being made of stainless steel.

[0007] Preferably, the working component includes a first heat-conducting plate and a second heat-conducting plate, both of which are disposed on the push plate and located on the same side, and the length of the first heat-conducting plate is longer than the length of the second heat-conducting plate. The first heat-conducting plate and the second heat-conducting plate are slidably engaged with the two heat-conducting blocks respectively. The first position is when the first heat-conducting plate is in contact with both heat-conducting blocks at the same time and the second heat-conducting plate is not in contact with the heat-conducting blocks. The second position is when the first heat-conducting plate and the second heat-conducting plate are in contact with the two heat-conducting blocks respectively. The working component also includes two third heat-conducting plates, which are perpendicularly connected to the first heat-conducting plate and the second heat-conducting plate, respectively.

[0008] Preferably, the working component further includes a plurality of first heat dissipation fins and two second heat dissipation fins disposed on the cabinet. The working component also includes two sets of first heat conduction pipes disposed inside the cabinet and connected to the first heat dissipation fins. One end of the first heat dissipation fins and one end of the second heat dissipation fins both pass through the cabinet and extend to the outside of the cabinet. An outer guide plate is vertically arranged at the end of the first heat pipe away from the first heat dissipation fin in each group. A fourth heat-conducting plate is arranged at the end of the outer guide plate away from the first heat pipe. The third heat-conducting plate and the fourth heat-conducting plate are in sliding contact to transfer heat from the third heat-conducting plate to the fourth heat-conducting plate. Flexible graphite is provided at the end of the fourth heat-conducting plate near the third heat-conducting plate and at the end of the heat-conducting block near the connecting plate to enhance the heat transfer effect.

[0009] Preferably, the outer guide plate is annular, and a partition ring is provided inside the outer guide plate. An inner guide plate is provided inside the partition ring. The partition ring is used to isolate the outer guide plate and the inner guide plate to prevent the heat of the inner guide plate from being transferred to the outer guide plate. The thermal resistance of the inner guide plate is less than that of the outer guide plate, so that heat is preferentially transferred from the fourth heat-conducting plate to the inner guide plate. One end of the inner guide plate is fixedly connected to the fourth heat-conducting plate, and the other end of the inner guide plate is vertically provided with a second heat-conducting pipe. A thermoelectric generator is provided at the end of the second heat-conducting pipe away from the inner guide plate, and the end of the thermoelectric generator away from the second heat-conducting pipe is connected to the second heat dissipation fin. The heat-conducting block, the first heat-conducting plate, the second heat-conducting plate, the third heat-conducting plate, and the fourth heat-conducting plate are all made of copper.

[0010] Preferably, the cabinet is equipped with an energy storage module, which is electrically connected to the thermoelectric generator and is used to store the electricity generated by the thermoelectric generator.

[0011] Preferably, a fan is provided at the end of the first heat dissipation fin away from the thermoelectric generator, and a sensor connected to the energy storage module 432 is provided inside the cabinet to detect the energy storage capacity of the energy storage module.

[0012] This invention provides a switch cabinet with a dual safety protection structure. It has the following advantages: I. This switchgear with a dual safety protection structure, through the installation of an adjustment component, allows the temperature sensing element to contract at low temperatures. A spring pushes a connecting plate, which in turn moves the first and second heat-conducting plates synchronously, ensuring the first heat-conducting plate simultaneously contacts both heat-conducting blocks. At this time, the heat from the first type of electrical components is transferred to the second type of electrical components through the connected heat-conducting blocks, the first heat-conducting plate, and the other heat-conducting block, thus maintaining both types of electrical components at normal temperatures and preventing the second type of electrical components from failing due to condensation at low temperatures. At high temperatures, the temperature sensing element expands, pushing the push plate, push rod, and connecting plate to move synchronously and compressing the spring. At this time, the first and second heat-conducting plates respectively contact their corresponding heat-conducting blocks.

[0013] II. This switchgear with a dual safety protection structure, through its designed working components, ensures that under high-temperature conditions, the heat from the first type of electrical components is transferred to the fourth heat-conducting plate via the first and third heat-conducting plates. The second type of electrical components also transfer heat to the fourth heat-conducting plate via the second and third heat-conducting plates. The heat from the fourth heat-conducting plate is preferentially conducted to the hot end of the thermoelectric generator via the inner guide plate and the second heat-conducting pipe. The thermoelectric generator generates electricity using the temperature difference between its hot end and the cold end, which is cooled by the second heat dissipation fins, and then transmits the electrical energy to the energy storage module for storage. The remaining heat is directly dissipated through the outer guide plate and the first heat-conducting pipe to the first heat dissipation fins. When the energy storage module reaches a threshold during energy storage, indicating an abnormal temperature rise within the cabinet, the sensor sends a signal to the backend. The backend then activates the cooling fan via an external power source. The cooling fan forces convection heat exchange onto the first heat dissipation fins, continuously accelerating the removal of heat from the fins, thereby improving heat dissipation efficiency and ultimately reducing the temperature of both the first and second type of electrical components.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0017] like Figure 1 and Figure 2 As shown, the present invention provides a technical solution: a switch cabinet with a dual safety protection structure, comprising a cabinet body 1, a first type of electrical component 2, a second type of electrical component 3, and an adjustment mechanism 4. The first type of electrical component 2 and the second type of electrical component 3 are both located inside the cabinet body 1. The adjustment mechanism 4 adjusts its position according to temperature to achieve temperature management and heat dissipation regulation of the first type of electrical component 2 and the second type of electrical component 3, thereby improving the safety and reliability of equipment operation.

[0018] like Figures 4 to 9As shown, the adjustment mechanism 4 includes an adjustment component 41 and a working component 42 disposed inside the cabinet 1. When the temperature is lower than the first preset temperature, the adjustment component 41 adjusts the position of the working component 42 to the first working position, so that the heat of the first type of electrical component 2 is transferred to the second type of electrical component 3, so that the first type of electrical component 2 and the second type of electrical component 3 operate at a relatively balanced temperature, avoiding damage to the first type of electrical component 2 due to excessive temperature, and preventing the second type of electrical component 3 from becoming damp and condensing due to excessively low temperature. When the temperature is higher than the second preset temperature, the adjustment component 41 adjusts the position of the working component 42 to the second working position, so that the working component 42 dissipates heat from the first type of electrical component 2 and the second type of electrical component 3 respectively, and generates electricity through temperature difference. When the power generation reaches the threshold, that is, the temperature inside the cabinet 1 is abnormal, the working component 42 strengthens the heat dissipation of the second type of electrical component 3 and the first type of electrical component 2, so that the first type of electrical component 2 and the second type of electrical component 3 operate at a relatively balanced temperature, preventing damage to the first type of electrical component 2 and the second type of electrical component 3 due to prolonged operation at high temperature.

[0019] The cabinet 1 has a partition 5 on its inner wall. The adjustment mechanism 4 also includes two heat-conducting blocks 43. The two heat-conducting blocks 43 are both set on the partition 5 and connected to the first type of electrical component 2 and the second type of electrical component 3 respectively through multiple heat-conducting wires, so that the adjustment mechanism 4 can realize temperature control of the first type of electrical component 2 and the second type of electrical component 3.

[0020] It should be noted that circuit breakers, disconnect switches, current transformers, voltage transformers, and transformers belong to the first category of electrical components 2, while instruments, relays, and temperature and humidity controllers belong to the second category of electrical components 3. The first category of electrical components 2 are located in the lower middle part of cabinet 1, and the second category of electrical components 3 are located in the upper part of cabinet 1. The first category of electrical components 2 are connected to a heat-conducting block 43 via a heat-conducting wire, and the second category of electrical components 3 are connected to another heat-conducting block 43 via a heat-conducting wire. The two heat-conducting blocks 43 respectively concentrate the heat from the first category of electrical components 2 and the second category of electrical components 3, facilitating heat transfer. The first preset temperature and the second preset temperature are 10°C and 30°C, respectively. When the temperature is below the first preset temperature (low temperature state), the working component 42 is in the first working position; when the temperature is between the first and second preset temperatures (normal state), the working component 42 is in the second working position; when the temperature is above the second preset temperature (high temperature state), the working component 42 is in the second working position.

[0021] like Figures 4 to 8As shown, the adjustment assembly 41 includes a housing 411 disposed on the inner wall of the cabinet 1. A temperature sensing component 412 is disposed inside the housing 411. A push plate 413, which slides inside the housing 411, is disposed at one end of the temperature sensing component 412. A push rod 414, penetrating the housing 411, is disposed at the end of the push plate 413 away from the temperature sensing component 412. A connecting plate 415 is disposed at the end of the push rod 414 away from the push plate 413. A spring 416 is disposed at the end of the connecting plate 415 away from the push rod 414. The other end of the spring 416 is disposed on the inner wall of the housing 411. The spring 416 is made of stainless steel. The stainless steel spring 416 maintains a fixed elasticity during use, preventing excessive elasticity from affecting the operation of the temperature sensing component 412. When the temperature drops, the temperature sensing component 412 contracts, and the connecting plate 415 returns to its original position via the spring 416.

[0022] Specifically, the temperature sensing component 412 uses paraffin wax as the temperature sensing medium, which can sense temperature changes inside the cabinet 1. The connecting plate 415 is made of engineering ceramics with low thermal conductivity, so it will not affect the heat transfer of the working component 42. When the internal temperature of the cabinet 1 is low, the paraffin wax shrinks in volume. At this time, the spring 416 pushes the connecting plate 415, push rod 414, and push plate 413 to move upward synchronously, and the push plate 413 will move linearly inside the housing 411. When the internal temperature of the cabinet 1 rises, the paraffin wax melts and expands, increasing in volume, pushing the push plate 413, push rod 414, and connecting plate 415 to move downward synchronously and compressing the spring 416.

[0023] like Figures 4 to 9 As shown, the working assembly 42 includes a first heat-conducting plate 421 and a second heat-conducting plate 422. Both the first and second heat-conducting plates 421 and 422 are mounted on the push plate 413 and located on the same side. The length of the first heat-conducting plate 421 is longer than the length of the second heat-conducting plate 422. The first and second heat-conducting plates 421 and 422 are slidably engaged with two heat-conducting blocks 43, respectively. A first position is where the first heat-conducting plate 421 is in contact with both heat-conducting blocks 43 simultaneously, while the second heat-conducting plate 422 is not in contact with any of the heat-conducting blocks 43. A second position is where the first and second heat-conducting plates 421 and 422 are in contact with both heat-conducting blocks 43, respectively. By adjusting the position of the first heat-conducting plate 421, the temperature of the first type of electrical component 2 and the second type of electrical component 3 can be adjusted. The working assembly 42 also includes two third heat-conducting plates 423, which are perpendicularly connected to the first and second heat-conducting plates 421 and 422, respectively, for heat transfer.

[0024] Specifically, when in a low-temperature state, the temperature sensing component 412 contracts, causing the connecting plate 415 to move upward. Simultaneously, the connecting plate 415 moves the first heat-conducting plate 421 and the second heat-conducting plate 422 together. At this time, the first heat-conducting plate 421 simultaneously contacts both heat-conducting blocks 43, reaching the first working position, thus connecting the first type of electrical component 2 with the second type of electrical component 3. The heat from the first type of electrical component 2 is then transferred to the first heat-conducting plate 421 through the heat-conducting wire and the heat-conducting block 43, and then transferred through the first heat-conducting plate 421 to the other heat-conducting block 43. The other heat-conducting block 43 then transfers the heat to the second type of electrical component 3 through the heat-conducting wire, causing the second type of electrical component 3 to heat up and preventing damage at low temperatures. During the heat conduction process, the first type of electrical component 2 gradually cools down, ensuring that both the second type of electrical component 3 and the first type of electrical component 2 are at a relatively balanced temperature.

[0025] The working component 42 also includes a plurality of first heat dissipation fins 430 and two second heat dissipation fins 434 disposed on the cabinet 1. In this embodiment, the number of first heat dissipation fins 430 is four. The working component 42 also includes two sets of first heat conduction pipes 428 disposed inside the cabinet 1 and connected to the first heat dissipation fins 430. In this embodiment, the number of first heat conduction pipes 428 in each set is four. One end of the first heat dissipation fin 430 and one end of the second heat dissipation fin 434 both pass through the cabinet 1 and extend to the outside of the cabinet 1, so as to dissipate heat from the first heat dissipation fins 430 by means of external airflow. Each group of first heat pipes 428 has an outer guide plate 425 vertically arranged at the end away from the first heat dissipation fins 430. The outer guide plate 425 has a fourth heat plate 424 arranged at the end away from the first heat pipe 428. The third heat plate 423 and the fourth heat plate 424 are in sliding contact to allow heat to be transferred from the third heat plate 423 to the fourth heat plate 424.

[0026] Flexible graphite 435 is provided at one end of the fourth heat-conducting plate 424 near the third heat-conducting plate 423 and at one end of the heat-conducting block 43 near the connecting plate 415 to enhance heat transfer. Specifically, the flexible graphite 435 on the fourth heat-conducting plate 424 and the second heat-conducting plate 422 can significantly reduce contact thermal resistance and also act as a lubricant to enhance heat transfer between the fourth heat-conducting plate 424 and the third heat-conducting plate 423 and reduce friction between them; enhance heat transfer between the heat-conducting block 43 and the second heat-conducting plate 422 and reduce friction between them; and enhance heat transfer between the heat-conducting block 43 and the first heat-conducting plate 421 and reduce friction between them.

[0027] The outer guide plate 425 is annular, and a partition ring 427 is provided inside the outer guide plate 425. Inside the partition ring 427 is an inner guide plate 426. The partition ring 427 isolates the outer guide plate 425 and the inner guide plate 426, preventing heat transfer from the inner guide plate 426 to the outer guide plate 425. The outer guide plate 425 is made of aluminum, and the inner guide plate 426 is made of copper. Copper has good thermal conductivity and low thermal resistance, while aluminum has higher thermal resistance than copper. The partition ring 427 is made of engineering ceramic, which has low thermal conductivity and will not transfer heat from the inner guide plate 426 to the outer guide plate 425.

[0028] One end of the inner guide plate 426 is fixedly connected to the fourth heat conduction plate 424, and the other end of the inner guide plate 426 is vertically provided with a second heat conduction pipe 429. A thermoelectric generator 431 is provided at the end of the second heat conduction pipe 429 away from the inner guide plate 426. The end of the thermoelectric generator 431 away from the second heat conduction pipe 429 is connected to the second heat dissipation fin 434, and the cold end of the thermoelectric generator 431 is cooled by the second heat dissipation fin 434.

[0029] It should be noted that the thermal resistance of the inner guide plate 426 is less than that of the outer guide plate 425, so that heat is preferentially transferred from the fourth heat-conducting plate 424 to the inner guide plate 426. The spacer ring 427 between the inner guide plate 426 and the outer guide plate 425 can isolate heat and prevent heat on the outer guide plate 425 from transferring to the inner guide plate 426, thereby allowing heat to preferentially transfer to the thermoelectric generator 431.

[0030] Specifically, when under high temperature conditions, the temperature sensing component 412 expands, causing the connecting plate 415 to move downwards. Simultaneously, the connecting plate 415 causes the first heat-conducting plate 421 and the second heat-conducting plate 422 to move together. At this time, the first heat-conducting plate 421 and the second heat-conducting plate 422 are respectively connected to the two heat-conducting blocks 43. That is, the first heat-conducting plate 421 is connected to the first type of electrical component 2, and the second heat-conducting plate 422 is connected to the second type of electrical component 3. The first heat-conducting plate 421 will transfer the heat of the first type of electrical component 2 to the lower third heat-conducting plate 423 and the lower fourth heat-conducting plate 424 through the upper third heat-conducting plate 423. The second heat-conducting plate 422 will transfer the heat of the second type of electrical component 3 to the upper fourth heat-conducting plate 424 through the upper third heat-conducting plate 423. When the fourth heat-conducting plate 424 receives heat, the heat is preferentially transferred to the inner heat-conducting plate 426. The inner heat-conducting plate 426 transfers the heat to the hot end of the thermoelectric generator 431. The thermoelectric generator 431 then transfers the heat from the hot end to the cold end, generating electricity through the temperature difference between the hot and cold ends. The cold end transfers the remaining heat to the second heat dissipation fin 434 for heat dissipation. The heat that is not transferred to the thermoelectric generator 431 is transferred to the outer heat-conducting plate 425 through the fourth heat-conducting plate 424. The outer heat-conducting plate 425 then transfers the heat to the first heat dissipation fin 430 for heat dissipation.

[0031] It should be noted that the heat-conducting block 43, the first heat-conducting plate 421, the second heat-conducting plate 422, the third heat-conducting plate 423, the fourth heat-conducting plate 424, the first heat-conducting pipe 428, and the second heat-conducting pipe 429 are all made of copper. Copper has good thermal conductivity and can quickly transfer heat, thereby improving the heat dissipation effect on the first type of electrical component 2 and the second type of electrical component 3.

[0032] The cabinet 1 houses an energy storage module 432, which is electrically connected to a thermoelectric generator 431 to store the electricity generated by the thermoelectric generator 431. A fan 433 is installed at the end of the first heat sink 430 away from the thermoelectric generator 431. The cabinet 1 also houses a sensor 436 connected to the energy storage module 432 to detect the amount of electricity stored in the energy storage module 432.

[0033] Specifically, under high-temperature conditions, the first type of electrical component 2 and the second type of electrical component 3 heat up, and the first heat sink 430 cools them down. During the cooling process, the thermoelectric generator 431 continuously absorbs heat and generates electricity, which is collected by the energy storage module 432. When the amount of electricity collected by the energy storage module 432 reaches a set threshold, it indicates that the temperature difference between the hot and cold ends of the thermoelectric generator 431 is continuously increasing, meaning that the temperature of the first type of electrical component 2 and the second type of electrical component 3 is abnormally high. At this time, the sensor 436 transmits a signal to the backend, which then activates an external power supply to power the fan 433, enabling the fan 433 to enhance heat dissipation of the first heat sink 430, thereby rapidly reducing the temperature of the first type of electrical component 2 and the second type of electrical component 3. While the sensor 436 transmits the signal, it also consumes the amount of electricity collected by the energy storage module 432, keeping the amount below the threshold to facilitate continued electricity collection and monitoring.

[0034] Working principle: When the temperature is low, the temperature sensing component 412 contracts, and the spring 416 pushes the connecting plate 415, push rod 414, and push plate 413 to move synchronously. The push plate 413 moves inside the housing 411, and the connecting plate 415 simultaneously drives the first heat-conducting plate 421 and the second heat-conducting plate 422 to move together. At this time, the first heat-conducting plate 421 simultaneously contacts the two heat-conducting blocks 43, reaching the first working position, that is, the first type of electrical component 2 and the second type of electrical component 3 are connected. At this time, the heat of the first type of electrical component 2 is transferred to the heat-conducting block 43 through the heat-conducting wire, and then transferred to the other heat-conducting block 43 through the heat-conducting block 43 and the first heat-conducting plate 421. The other heat-conducting block 43 then transfers the heat to the second type of electrical component 3 through the heat-conducting wire, causing the second type of electrical component 3 to heat up. The first type of electrical component 2 will gradually cool down during the heat conduction process, so that the second type of electrical component 3 and the first type of electrical component 2 are both at a relatively balanced temperature.

[0035] When in a high-temperature state, the temperature sensing component 412 expands, pushing the push plate 413 and push rod 414, and causing the connecting plate 415 to move downward and compress the spring 416. The connecting plate 415 simultaneously drives the first heat-conducting plate 421 and the second heat-conducting plate 422 to move together. At this time, the first heat-conducting plate 421 and the second heat-conducting plate 422 are respectively connected to the two heat-conducting blocks 43. That is, the first heat-conducting plate 421 is connected to the first type of electrical component 2, and the second heat-conducting plate 422 is connected to the second type of electrical component 3. The first heat-conducting plate 421 will transfer the heat of the first type of electrical component 2 to the lower third heat-conducting plate 423 and the lower fourth heat-conducting plate 424 through the lower third heat-conducting plate 423. The second heat-conducting plate 422 will transfer the heat of the second type of electrical component 3 to the upper third heat-conducting plate 423 and the upper fourth heat-conducting plate 424 through the upper third heat-conducting plate 423. When the fourth heat-conducting plate 424 receives heat, the heat is preferentially transferred to the inner heat-conducting plate 426 with lower thermal resistance. The inner heat-conducting plate 426 transfers the heat to the hot end of the thermoelectric generator 431 through the second heat-conducting pipe 429. The thermoelectric generator 431 then transfers the heat from the hot end to the cold end and generates electricity using the temperature difference between the hot and cold ends. The cold end transfers the remaining heat to the second heat dissipation fin 434 for heat dissipation. The heat on the fourth heat-conducting plate 424 that is not transferred to the thermoelectric generator 431 is transferred to the outer heat-conducting plate 425. The outer heat-conducting plate 425 transfers the heat to the first heat dissipation fin 430 through the first heat-conducting pipe 428 for heat dissipation.

[0036] During the cooling process of the first type of electrical component 2 and the second type of electrical component 3, the thermoelectric generator 431 continuously absorbs heat and generates electrical energy. This electrical energy is collected by the energy storage module 432. When the amount of electricity collected by the energy storage module 432 reaches a set threshold, it indicates that the temperature difference between the hot and cold ends of the thermoelectric generator 431 is continuously increasing, meaning that the temperatures of the first type of electrical component 2 and the second type of electrical component 3 are abnormally high. At this time, the sensor 436 transmits a signal to the backend, which then activates an external power supply to power the fan 433. This allows the fan 433 to enhance heat dissipation of the first heat sink 430, thereby rapidly reducing the temperatures of the first type of electrical component 2 and the second type of electrical component 3. While the sensor 436 transmits the signal, it also consumes the amount of electricity collected by the energy storage module 432, keeping the amount below the threshold to facilitate continued electricity collection and monitoring.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
