Description

Technical Field

[0001] This invention relates to the field of substation enclosure technology, and more specifically, to a substation enclosure with circulating air ducts and heat dissipation fins. Background Technology

[0002] In some coastal areas with high humidity and salt spray, the outside air surrounding substation enclosures often contains salt spray, corrosive acidic and alkaline gases, and dust. If the enclosure directly allows large amounts of air in for heat dissipation, these corrosive and polluting media will enter the enclosure with the airflow, adhering to the surfaces of equipment insulation components, contacts, and metal parts, causing corrosion, dirt accumulation, reduced insulation performance and contact reliability, and even triggering creepage, short circuits, or malfunctions. Therefore, existing equipment typically designs the enclosure as a relatively enclosed structure with heat dissipation fins on the enclosure walls: part of the fins is located inside the enclosure to absorb heat; the other part extends outside the enclosure to release heat to the outside environment, and the penetration points usually need to be sealed. Heat inside the enclosure is conducted to the outside through the fins, thus achieving heat dissipation without introducing large amounts of polluted outside air.

[0003] However, after long-term operation, even if the fins are made of corrosion-resistant materials, their surfaces will still accumulate impurities and gradually form scale due to the combined effects of salt spray, dust, and moisture. This scale layer increases the thermal resistance between the fins and the air, weakening heat conduction and dissipation. Furthermore, when there is a large temperature difference between the inside and outside of the enclosure or when the ambient temperature changes drastically, existing fixed fins cannot actively adjust their heat dissipation. They cannot change their heat dissipation capacity according to the internal temperature and the heat generated by the equipment, causing significant fluctuations in the internal temperature with the ambient temperature. This affects the stability, reliability, and lifespan of temperature-sensitive electronic components, and in severe cases, may even induce condensation. Summary of the Invention

[0004] To overcome the shortcomings of scale buildup on the surface of heat sink fins affecting heat dissipation, and the inability of existing fins to actively adjust heat dissipation, which causes significant fluctuations in the internal temperature of the enclosure with the external ambient temperature, thus affecting the electronic components inside, this invention provides a substation enclosure with a circulating air duct and heat sink fins.

The inner side of the box slides; several partitions are fixedly connected to the inner side of the channel component, and the partitions are fixedly connected to the corresponding heat-conducting plates; the space between the box body, the box door and the piston plate forms a cavity one below the piston plate, and the space above the piston plate forms a cavity two; each channel component has an opening; several air ducts are formed between the channel component and the partitions, the lower part of the air duct is connected to cavity one, and the upper part is connected to cavity one through the corresponding opening; each air duct has a fan, and the fan is fixedly connected to the corresponding channel component and partition; each channel component has a temperature sensor fixedly connected to it.

[0006] Furthermore, the top of the box has two symmetrical bevels.

[0007] The present invention achieves a flow guiding effect by adopting the above structure.

[0008] Furthermore, it also includes auxiliary components, including one-way valve 1, one-way valve 2, and heat insulation plates; piston plate 1 has several circular holes 1; cavity 1 communicates with cavity 2 through the circular holes 1; several one-way valves 1 are installed on piston plate 1, and the one-way valves 1 are located in the corresponding circular holes 1; air in cavity 2 can enter cavity 1 through one-way valves 1; several one-way valves 2 are installed on the housing; outside air can enter cavity 2 through one-way valves 2; two heat insulation plates are fixedly connected to each heat-conducting plate, the heat insulation plates are fixedly connected to piston plate 1, and the heat insulation plates are slidably connected to the housing and the top of the housing.

[0009] Furthermore, the partition is made of a thermally conductive material.

[0010] The present invention achieves heat dissipation effect by adopting the above structure.

[0011] Furthermore, it also includes a fan shroud; several fan shrouds are fixedly connected to the lower side of the piston plate, and the fan shrouds are fixedly connected to the corresponding heat-conducting plates; each fan shroud is provided with a cavity three, and the cavity three is connected to the corresponding round hole one; each fan shroud is provided with several round holes two, and the round holes two are connected to the corresponding cavity three and cavity one.

[0012] Furthermore, it also includes lighting; several lighting lamps are fixedly attached to one of the piston plates.

[0014] Furthermore, it also includes a smoke sensor; a smoke sensor is fixedly installed in each channel component.

[0015] Furthermore, it also includes an alarm light; an alarm light is fixed to the top of the box.

[0016] Furthermore, a sealing strip is installed on the door.

[0017] Furthermore, a sealing strip is provided on the piston plate.

[0018] The present invention achieves a sealing effect by adopting the above structure.

[0019] Compared with the prior art, the present invention has the following advantages: First, by moving the heat-conducting plate with an electric push rod, the area of ​​the heat-conducting plate extending outside the top part of the box can be adjusted according to the temperature of the external environment, thereby adjusting the degree of heat dissipation. This makes the temperature fluctuation of the circulating airflow smaller when the external environment temperature changes frequently, avoiding damage to electronic components due to temperature fluctuations. Furthermore, when the electric push rod moves the heat-conducting plate, the scale on the surface of the heat-conducting plate can be scraped off through the top part of the box, avoiding a decrease in heat dissipation efficiency due to scale formation on the surface of the heat-conducting plate. Second, with the combined action of one-way valve one, one-way valve two and heat insulation plate, when the air temperature in cavity one rises, the upward-moving piston plate one can also squeeze the air in cavity two into cavity one, thereby accelerating the rate at which the air temperature in cavity one drops. Combined with the extended heat-conducting plate, this allows the air temperature in cavity one to drop back to the normal range more quickly. Third, by pressurizing the air flowing out of the one-way valve through the fan shroud, the flow rate and jet distance are increased, so that this part of the air can directly impact the surface of the electronic components, thereby improving the cooling efficiency of the electronic components.

Detailed Implementation

[0022] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] Example 1: A substation enclosure with circulating air ducts and heat dissipation fins, such as... Figures 1-8 As shown, the enclosure includes a housing 1 and a door 2; the door 2 is rotatably connected to the housing 1; it also includes a top component 3, electric push rods 4, piston plate 5, heat-conducting plate 6, channel components 7, partitions 8, a fan 9, and a temperature sensor 10; the top component 3 is bolted to the housing 1; two electric push rods 4 are fixedly connected to the top component 3, and the electric push rods 4 are fixedly connected to the top of the housing 1; the extension ends of all the electric push rods 4 are fixedly connected to the piston plate 5, and the piston plate 5 is slidably connected to the housing 1; several heat-conducting plates 6 are threaded through the piston plate 5, and the heat-conducting plates 6 are slidably connected to the top of the housing 1 and to the top component 3; two channel components 7 are bolted to the piston plate 5, and the channel components 7 slide inside the housing 1; several partitions 8 are bolted to the inside of the channel components 7. The partition 8 is fixedly connected to the corresponding heat-conducting plate 6; the space between the box body 1, the box door 2 and the piston plate 5 below the piston plate 5 forms a cavity 191; the space above the piston plate 5 forms a cavity 192; each channel component 7 has an opening 193; several air ducts 194 are formed between all the channel components 7 and the partition 8, the lower part of the air duct 194 is connected to the cavity 191, and the upper part of the air duct 194 is connected to the cavity 191 through the corresponding opening 193; each air duct 194 is equipped with a fan 9, the fan 9 is fixedly connected to the corresponding channel component 7, and the fan 9 is fixedly connected to the corresponding partition 8; each channel component 7 is bolted with a temperature sensor 10, and the temperature in the cavity 191 is monitored by the temperature sensor 10.

[0024] The top part 3 has two symmetrical inclined surfaces on its upper side, which guide rainwater and impurities.

[0025] During operation, fan 9 is activated, causing the air in the air duct 194 to move downwards. This allows the air in the upper part of cavity 191 to flow into the air duct 194 through opening 193, then into the lower part of cavity 191 from the lower end of the air duct 194, and then back up from the lower part of cavity 191 to the upper part of cavity 191, thus forming a circulating airflow. Substation electronic components are installed inside cavity 191 of housing 1. These components generate heat during operation, which is then conducted into the circulating airflow. The circulating airflow contacts the lower part of heat-conducting plate 6, allowing this heat to be conducted to the external environment, completing the heat dissipation operation. When the external ambient temperature rises, the heat-conducting plate 6's ability to dissipate heat to the external environment decreases. The decrease in ambient temperature reduces the heat dissipation effect, causing the air temperature inside cavity 191 to rise. Conversely, when the ambient temperature decreases, the heat-conducting plate 6's ability to dissipate heat to the environment increases, improving heat dissipation and causing the air temperature inside cavity 191 to decrease. If the frequency and amplitude of ambient temperature changes are large, the air temperature inside cavity 191 will fluctuate significantly, affecting the stability, reliability, and lifespan of temperature-sensitive electronic components. Therefore, a temperature sensor 10 is installed on channel component 7. During heat dissipation, the temperature of the circulating airflow is monitored by the temperature sensor 10. When the detected temperature is too high, the electric push rod 4 drives the piston plate 5 to move upward, and the piston plate 5 drives the heat-conducting plate 6 to move upward. This design allows more of the heat-conducting plate 6 to extend beyond the outer side of the top part 3, increasing the heat exchange area between the heat-conducting plate 6 and the external environment, thus improving heat dissipation and lowering the temperature of the circulating airflow. When the detected temperature is too low, the electric push rod 4 drives the piston plate 5 downward, which in turn drives the heat-conducting plate 6 downward, reducing the area of ​​the heat-conducting plate 6 extending beyond the outer side of the top part 3. This further reduces the heat exchange area between the heat-conducting plate 6 and the external environment, improving heat dissipation and increasing the temperature of the circulating airflow. This minimizes temperature fluctuations in the circulating airflow when the ambient temperature changes frequently, preventing damage to electronic components due to temperature fluctuations. When the electric push rod 4 drives the piston plate 5 downward, the piston plate 5 drives the heat-conducting plate 6 downward. The top component 3 scrapes off the scale buildup on the surface of the heat-conducting plate 6. The scraped-off impurities slide down the slope of the top component 3 to the ground, achieving a cleaning operation and preventing a decrease in heat dissipation efficiency due to scale buildup on the surface of the heat-conducting plate 6. During use, the electric push rod 4 moves the heat-conducting plate 6, adjusting the area of ​​the heat-conducting plate 6 extending beyond the top component 3 according to the ambient temperature, thereby regulating the degree of heat dissipation. This minimizes temperature fluctuations in the circulating airflow when the ambient temperature changes frequently, preventing damage to electronic components due to temperature fluctuations. Furthermore, when the electric push rod 4 moves the heat-conducting plate 6, the top component 3 scrapes off the scale buildup on the surface of the heat-conducting plate 6, preventing a decrease in heat dissipation efficiency due to scale buildup on the surface of the heat-conducting plate 6.

[0026] It also includes auxiliary components, including a one-way valve 201, a one-way valve 202, and a heat insulation plate 203; the piston plate 5 has several circular holes 195; the cavity 191 is connected to the cavity 292 through the circular holes 195; several one-way valves 201 are installed on the piston plate 5, and the one-way valves 201 are located in the corresponding circular holes 195; air in the cavity 292 can enter the cavity 191 through the one-way valves 201; several one-way valves 202 are installed on the housing 1; outside air can enter the cavity 292 through the one-way valves 202; two heat insulation plates 203 are fixedly connected to each heat-conducting plate 6, and the heat insulation plates 203 are fixedly connected to the piston plate 5 and slidably connected to the housing 1 and the top part 3.

[0027] The partition 8 is made of a thermally conductive material. Some of the heat on the heat-conducting plate 6 is conducted to the partition 8, and then conducted to the air by the partition 8, which helps to improve the heat dissipation effect.

[0028] During heat dissipation, the heat on the heat-conducting plate 6 is isolated by the heat insulation plate 203, significantly reducing the heat exchange between the air in cavity one 191 and the air in cavity two 192 through the heat-conducting plate 6. Furthermore, cavity two 192 is connected to the external environment through the one-way valve two 202, allowing the air temperature inside cavity two 192 to approach the ambient air temperature. When the air temperature in cavity one 191 rises, the electric push rod 4 drives the piston plate one 5 and the heat-conducting plate 6 upwards, extending more of the heat-conducting plate 6 to enhance heat dissipation. During this process, the upward-moving piston plate one 5 compresses the air in cavity two 192, thus reducing the heat exchange in cavity two 192. Air flows into cavity 191 through one-way valve 201, which accelerates the temperature drop of the air in cavity 191. Combined with the extended heat-conducting plate 6, this allows the air temperature in cavity 191 to return to normal more quickly. During use, the combined action of one-way valve 201, one-way valve 202, and heat insulation plate 203 causes the air temperature in cavity 191 to rise. The upward-moving piston plate 5 also compresses the air in cavity 292 into cavity 191, thus accelerating the temperature drop of the air in cavity 191. This, combined with the extended heat-conducting plate 6, allows the air temperature in cavity 191 to return to normal more quickly.

[0029] It also includes a fan shroud 204; several fan shrouds 204 are fixedly connected to the lower side of the piston plate 5, and the fan shrouds 204 are fixedly connected to the corresponding heat-conducting plate 6. The fan shrouds 204 are made of alloy material; each fan shroud 204 is provided with a cavity 3 196, and the cavity 3 196 is connected to the corresponding round hole 195; each fan shroud 204 is provided with four round holes 2 197, the round holes 2 197 are connected to the corresponding cavity 3 196, and the round holes 2 197 are connected to the cavity 191.

[0030] During the heat dissipation process, when the piston plate 5 squeezes the air out of the cavity 192 through the one-way valve 201, the air flows into the cavity 196 of the fan shroud 204 through the one-way valve 201, and then sprays downward through the round hole 197. Since the diameter of the round hole 197 is relatively small, the air can increase its flow rate and distance after being sprayed out of the round hole 197, so that the air can directly impact the surface of the electronic components. Compared with the air in the cavity 191 being mixed (the temperature of the mixed air is higher than the temperature of the air sprayed out of the round hole 197) before contacting the surface of the electronic components, this method can improve the cooling efficiency of the electronic components. In use, the air flowing out of the one-way valve 201 is pressurized by the fan shroud 204 to increase its flow rate and spray distance, so that the air can directly impact the surface of the electronic components, thereby improving the cooling efficiency of the electronic components.

[0031] Example 2, based on Example 1, such as Figure 4 and Figure 5 As shown, it also includes a lighting lamp 205; two lighting lamps 205 are bolted to the piston plate 5, and lighting is provided by the lighting lamps 205.

[0032] It also includes a smoke sensor 206; a smoke sensor 206 is fixedly connected in each channel component 7.

[0033] It also includes an alarm light 207; the alarm light 207 is fixedly attached to the top part 3 of the box.

[0034] A sealing strip is installed on door 2 to improve sealing.

[0035] A sealing strip is provided on piston plate 5 to improve sealing.

[0036] During maintenance, the door 2 is opened manually, and lighting is provided by the light 205. Then, the electrical components inside the box 1 are maintained. During use, if the electrical components inside the box 1 spontaneously combust, the generated smoke will move to the smoke sensor 206 with the circulating airflow. After the smoke sensor 206 detects the smoke, it sends a fire signal to the control center and triggers the alarm light 207 to sound an alarm.
