Description

Technical Field

[0001] This invention relates to the field of transformer technology, and in particular to an integrated heat dissipation structure for a new energy transformer. Background Technology

[0002] With the continuous increase in electricity demand, transformers, as important equipment in the power system, are crucial. Among them, new energy transformers are specifically designed for renewable energy systems and emerging power application scenarios, serving fields such as wind power, photovoltaics, energy storage systems, and electric vehicle charging stations. Their core functions are to achieve efficient voltage transformation, isolation, and transmission of electrical energy, while adapting to the unique operational requirements of new energy systems, such as highly fluctuating loads, high-frequency power conversion, high power density, and complex environmental conditions (such as high temperature, high humidity, and salt spray).

[0003] The effectiveness of heat dissipation technology directly affects the safe operation and service life of transformers. Existing transformer heat dissipation methods mainly rely on air convection and natural heat dissipation, but under high load or high temperature environments, the heat dissipation efficiency often fails to meet actual needs.

[0004] Existing transformer cooling structures largely rely on air convection, especially in laminar flow conditions where flowing air forms a boundary layer on the heat sink surface, reducing heat transfer efficiency. Furthermore, while increasing airflow velocity can improve cooling at high temperatures, its cooling capacity remains limited. Introducing other cooling methods requires multiple devices, making control complex and inconvenient.

[0005] Existing transformers often fail to effectively utilize rainfall for heat dissipation during rain, resulting in decreased heat dissipation efficiency. Over long periods of operation, transformer heat sinks tend to accumulate dust and dirt, which significantly reduce heat exchange efficiency and affect heat dissipation performance.

[0006] In addition, existing methods for cleaning heat sinks often require manual intervention, which is inefficient and inconvenient.

[0007] The information disclosed in the background section of this invention is intended only to enhance the understanding of the general background of this invention, and should not be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art. Summary of the Invention

[0008] Therefore, it is necessary to provide an integrated heat dissipation structure for new energy transformers to address the problems of low heat dissipation efficiency and inability to fully utilize environmental conditions to optimize heat dissipation in existing transformers.

[0009] The above objectives are achieved through the following technical solutions:

[0010] An integrated heat dissipation structure for a new energy transformer, comprising:

[0011] The system comprises a main housing, a heat dissipation device, and an active mechanism. The heat dissipation device includes multiple heat sinks, multiple first opening and closing structures, and multiple second opening and closing structures. The multiple heat sinks are sequentially arranged outside the main housing along a first direction for dissipating heat from the coolant flowing out of the main housing. The first direction is perpendicular to the heat sinks. The first opening and closing structures and the second opening and closing structures are alternately arranged between every two adjacent heat sinks.

[0012] The heat dissipation device has a first mode, a second mode, and a third mode. In the first mode, the first opening and closing structure and the second opening and closing structure are stationary, forming an air turbulence structure between the heat sinks to enhance natural convection heat dissipation. In the second mode, the first opening and closing structure and the second opening and closing structure slide synchronously between the heat sinks to drive airflow and form forced convection heat dissipation. In the third mode, the sliding speeds of adjacent first opening and closing structures and the second opening and closing structure are different, and the first opening and closing structure and the second opening and closing structure hinder the flow of air between adjacent heat sinks.

[0013] The active mechanism seals the area between the adjacent first opening / closing structure, the second opening / closing structure and the heat sink in the third mode, so as to form a negative pressure area when the adjacent first opening / closing structure and the second opening / closing structure slide at different speeds.

[0014] Furthermore, the heat dissipation device has a first stage and a second stage in the third mode. In the first stage, the sliding speed of the first opening and closing structure is greater than that of the second opening and closing structure, and the negative pressure area is formed between the first opening and closing structure and the second opening and closing structure and the heat sink. In the second stage, the sliding speed of the second opening and closing structure is greater than that of the first opening and closing structure, and the negative pressure area is formed between the first opening and closing structure and the second opening and closing structure and the heat sink.

[0015] Furthermore, the first and second opening / closing structures are identical in structure, each including a first scraper and a second scraper, which are hinged together. When the first and second scrapers rotate away from the heat sink, the first and second opening / closing structures retract, allowing air to flow between adjacent heat sinks. When the first and second scrapers move towards the heat sink, the first and second opening / closing structures unfold, hindering air flow between the heat sinks.

[0016] Furthermore, the active mechanism includes a cover plate, the first scraper and the second scraper rotate toward the direction of the heat sink, the cover plate is in contact with the first scraper and the second scraper, and the negative pressure area is formed between the first scraper, the second scraper, the cover plate and the heat sink; the cover plate is detached from the first scraper and the second scraper, and the cover plate guides rainwater into the first opening and closing structure and the second opening and closing structure.

[0017] Furthermore, both the first opening and closing structure and the second opening and closing structure also include a hinge assembly, which is used to control the rotation of the first scraper and the second scraper to realize the opening and closing of the first opening and closing structure or the second opening and closing structure.

[0018] Furthermore, the hinge assembly includes a first hinge rod and a second hinge rod, the first hinge rod being hinged to the second hinge rod, the first hinge rod being hinged to the first scraper, and the second hinge rod being hinged to the second scraper.

[0019] Furthermore, the first opening and closing structure and the second opening and closing structure are connected by a linkage mechanism. The linkage mechanism can drive the first opening and closing structure and the second opening and closing structure to slide, and drive the first scraper and the second scraper to rotate, so as to control the opening and closing of the first opening and closing structure or the second opening and closing structure.

[0020] Furthermore, the linkage mechanism includes a first wire, a second wire, a third wire, and a fourth wire. The first wire passes through all the second opening and closing structures and sequentially connects the hinge positions of the first scraper and the second scraper of all the first opening and closing structures to drive all the first opening and closing structures to slide synchronously. The second wire passes through all the second opening and closing structures and sequentially connects the hinge positions of the first hinge rod and the second hinge rod of all the first opening and closing structures to drive all the first opening and closing structures to open or close synchronously. The third wire passes through all the first opening and closing structures and sequentially connects the hinge positions of the first scraper and the second scraper of all the second opening and closing structures to drive all the second opening and closing structures to slide synchronously. The fourth wire passes through all the first opening and closing structures and sequentially connects the hinge positions of the first hinge rod and the second hinge rod of all the second opening and closing structures to open or close synchronously.

[0021] Furthermore, when the heat dissipation device is in the first stage in the third mode, the rotation speed of the first wire and the second wire is greater than the rotation speed of the third wire and the fourth wire; when the heat dissipation device is in the second stage in the third mode, the rotation speed of the first wire and the second wire is less than the rotation speed of the third wire and the fourth wire.

[0022] Furthermore, the first wire, the second wire, the third wire, and the fourth wire are all loop coils connected end to end, so as to drive the multiple first opening and closing structures and the multiple second opening and closing structures to slide cyclically between the multiple heat sinks.

[0023] The beneficial effects of this invention are:

[0024] This invention provides an integrated heat dissipation structure for a new energy transformer, comprising a main housing, a heat dissipation device, and an active mechanism. The heat dissipation device includes heat sinks sequentially arranged outside the main housing along a first direction, and a first opening / closing structure and a second opening / closing structure alternately arranged between the heat sinks. The heat dissipation device has three operating modes: in the first mode, the first and second opening / closing structures are stationary, creating air turbulence to enhance natural convection cooling; in the second mode, the first and second opening / closing structures slide synchronously, forcing air convection cooling; in the third mode, adjacent first and second opening / closing structures slide at different speeds, hindering airflow between adjacent heat sinks. The active mechanism seals the area between adjacent first and second opening / closing structures and the heat sinks in the third mode, creating a negative pressure area when adjacent first and second opening / closing structures slide at different speeds. This invention significantly improves heat dissipation efficiency and adaptability through multi-mode coordination and dynamic turbulence optimization, solving the problem of insufficient heat dissipation efficiency in traditional heat dissipation structures.

[0047] The following reference Figures 1 to 14 This invention describes the integrated heat dissipation structure of a new energy transformer provided in an embodiment of the invention.

[0048] like Figure 1 and Figure 2 As shown, the integrated heat dissipation structure of the new energy transformer provided in this embodiment of the invention is particularly suitable for heat dissipation treatment of transformer 101, and can also be applied to heat dissipation needs under other operating conditions.

[0049] Specifically, the integrated heat dissipation structure of the new energy transformer includes a transformer 101, a cooling oil chamber 102, a heat dissipation device 200, and a main casing 100. The transformer 101 is used for power conversion; its internal structure is existing technology and will not be described in detail here. The cooling oil chamber 102 stores coolant, which can be insulating oil, to ensure the normal operation and insulation performance of the transformer 101. The heat dissipation device 200 is responsible for heat dissipation. The main casing 100 serves as the mounting base for other components, including the transformer 101, the cooling oil chamber 102, and the heat dissipation device 200. These components can be directly or indirectly mounted on the main casing 100, forming a relatively integrated whole after installation.

[0050] like Figure 2 As shown, the heat dissipation device 200 includes a plurality of heat sinks 201, which are sequentially arranged outside the main housing 100 along a first direction, which is a horizontal direction perpendicular to the heat sinks 201. Furthermore, the main housing 100 is provided with an oil outlet pipe 103 and an oil inlet pipe 104. The oil outlet pipe 103 is fixedly disposed at the upper end of the heat sink 201, while the oil inlet pipe 104 is fixedly disposed at the lower end of the heat sink 201. Both are connected to the interior of the heat sink 201.

[0051] Specifically, when current flows through the windings and core inside transformer 101, an alternating magnetic field is generated. During this process, the windings and core generate heat, causing the internal temperature of transformer 101 to rise. This heat must be controlled within specified limits; otherwise, transformer 101 may be damaged due to overheating. Therefore, insulating oil is needed to cool transformer 101.

[0052] When the temperature inside transformer 101 rises, the intermolecular distance of the insulating oil increases, causing it to expand in volume. The heated insulating oil, having increased in volume, rises to the top of the main casing 100 and then enters the heat sink 201 via the oil outlet pipe 103. Due to the gaps between the heat sink 201 fins, air can pass through these gaps, promoting heat dissipation and thus cooling the insulating oil. Finally, the cooled insulating oil returns to the main casing 100 through the oil inlet pipe 104 at the bottom, re-cooling the transformer 101. This process is continuously repeated, thereby improving heat dissipation efficiency.

[0053] like Figures 2 to 9As shown, the heat dissipation device 200 also includes a plurality of first opening and closing structures 210 and a plurality of second opening and closing structures 220. For example... Figure 5 and Figure 9 As shown, the first opening and closing structure 210 and the second opening and closing structure 220 are alternately arranged between adjacent heat sinks 201 along the second direction, which is perpendicular to the first direction.

[0054] Furthermore, the heat dissipation device 200 has a first mode, a second mode, and a third mode.

[0055] Specifically, when the internal temperature of transformer 101 rises and the temperature difference with the external environment is large, the air's heat dissipation effect on heat sink 201 is significant, and the heat dissipation device 200 is in its first mode. Both the first opening / closing structure 210 and the second opening / closing structure 220 are in a static, closed state, with their sides not contacting the surface of heat sink 201, forming a static turbulence structure that allows air to flow between heat sinks 201. Since air flowing through heat sink 201 is mostly laminar and has a viscous effect, it easily adheres to the surface of heat sink 201, forming a boundary layer. The presence of this boundary layer slows down the airflow adjacent to the surface of heat sink 201, thus reducing heat transfer efficiency. At this time, when air flows through the first opening / closing structure 210 and the second opening / closing structure 220, the turbulence structure formed by them can disrupt the laminar flow phenomenon, destroy the boundary effect, and cause turbulent airflow, thereby enhancing the natural convection heat dissipation effect and accelerating the diffusion of heat from the surface of heat sink 201 into the air.

[0056] When the temperature difference between the inside of transformer 101 and the external environment is moderate, the heat dissipation effect of air on heat sink 201 decreases, and the heat dissipation device 200 is in its second mode. Both the first opening / closing structure 210 and the second opening / closing structure 220 remain in their retracted state and slide synchronously through the gaps in the heat sink 201. Their movement trajectory is a continuous S-shape, passing through all the gaps in the heat sink 201 in sequence before returning to their initial position, forming a cyclical disturbance. During the sliding process, the sides of the first opening / closing structure 210 and the second opening / closing structure 220 do not contact the surface of the heat sink 201, thus forming a dynamic turbulence structure that drives the air to form a directional airflow, accelerating the airflow and achieving a forced convection heat dissipation effect, allowing hot air to be expelled more quickly and cold air to enter more quickly.

[0057] When the temperature difference between the inside of the transformer 101 and the outside environment is small, the air's heat dissipation effect on the heat sink 201 is not significant. At this time, the heat dissipation device 200 is in the third mode. Both the first opening and closing structure 210 and the second opening and closing structure 220 are deployed. The two sides of the first opening and closing structure 210 and the second opening and closing structure 220 are in contact with the surface of the heat sink 201, hindering the airflow between adjacent heat sinks 201.

[0058] In addition, the heat dissipation device 200 also includes an active mechanism 400. Normally, in the absence of rain, the active mechanism 400 is in contact with the first opening / closing structure 210 and the second opening / closing structure 220 between adjacent heat sinks 201. Therefore, when the first opening / closing structure 210 and the second opening / closing structure 220 unfold and contact the surface of the heat sink 201, a sealed chamber is formed between the adjacent first opening / closing structure 210 and the second opening / closing structure 220 and the heat sink 201, and the active mechanism 400 is used to seal the sealed chamber. At this time, due to the different sliding speeds of the first opening / closing structure 210 and the second opening / closing structure 220, they undergo relative displacement, resulting in a change in the air volume within the sealed chamber, thereby creating a negative pressure area. This, in turn, lowers the air temperature within the sealed chamber, thus optimizing the heat dissipation effect.

[0059] Specifically, in rainy weather, the active mechanism 400 disengages from the first opening / closing structure 210 and the second opening / closing structure 220. At this time, the first opening / closing structure 210 and the second opening / closing structure 220, located in the middle of the heat sink 201, are exposed to the external environment. Rainwater then flows into the interior of the first opening / closing structure 210 and the second opening / closing structure 220, thereby cooling the heat sink 201. Simultaneously, as air flows between the heat sinks 201, it carries impurities that adhere to the surface of the heat sink 201, affecting the device's heat dissipation performance. The active mechanism 400 can also use rainwater to wash away these impurities. The washed-away impurities are discharged from the heat dissipation device 200 through the sliding of the first opening / closing structure 210 and the second opening / closing structure 220, further enhancing the heat dissipation effect.

[0060] In one embodiment, the heat dissipation device 200 has a first stage and a second stage in the third mode. Specifically, as shown... Figure 5 and Figure 6 As shown, in the gap between adjacent heat sinks 201, the first opening / closing structure 210 is farther from the center of the heat sink 201 than the second opening / closing structure 220. This is the first stage. The sliding speed of the first opening / closing structure 210 is greater than that of the second opening / closing structure 220, reducing the pressure in the sealed chamber between them, thereby lowering the air temperature inside the sealed chamber and optimizing the heat dissipation effect. Because the first opening / closing structure 210 and the second opening / closing structure 220 are alternately arranged and continuously slide, the negative pressure environment in the sealed chamber between them is broken when the first opening / closing structure 210 moves from the heat sink 201 to the gap of the next heat sink 201. Simultaneously, during this process, the positions of the first opening / closing structure 210 and the second opening / closing structure 220 gradually interchange, so the sliding speed of the second opening / closing structure 220 is now greater than that of the first opening / closing structure 210. This is the second stage. Similarly, the pressure in the sealed chamber between them decreases, thereby lowering the air temperature inside the sealed chamber and optimizing the heat dissipation effect.

[0061] In one embodiment, such as Figures 10 to 12 As shown, both the first opening and closing structure 210 and the second opening and closing structure 220 include a first scraper 231 and a second scraper 232, which are hinged together.

[0062] Furthermore, such as Figures 2 to 5 As shown, the active mechanism 400 adopts a two-layer structure, and these two layers are identical. The active mechanism 400 includes an electric push rod 401, a connecting push rod 402, a movable plate 403, a driven rod 404, a connecting ring 406, and a cover plate 405. The outer shell of the electric push rod 401 is fixedly connected to the main shell 100, and the actuating component inside the electric push rod 401 is fixedly connected to the connecting push rod 402, which in turn is slidably connected to the movable plate 403. The movable plate 403 consists of a pair of openable and closable movable blades, which are hinged together by the connecting ring 406 and fixedly connected to the driven rod 404. The other end of the driven rod 404 extends to the cover plate 405 to achieve power transmission. Among them, the cover plate 405 is a key component, such as... Figure 2 and Figure 3 As shown, the cover plate 405 is sequentially disposed in the gap between adjacent heat sinks 201 along the first direction, and is in contact with the first opening and closing structure 210 and the second opening and closing structure 220.

[0063] Specifically, in the absence of rain, the first scraper 231 and the second scraper 232 rotate towards the heat sink 201, causing the first opening and closing structure 210 and the second opening and closing structure 220 to unfold and contact the surface of the heat sink 201. At this time, both the upper and lower cover plates 405 are in contact with the first scraper 231 and the second scraper 232 of the first opening and closing structure 210 and the second opening and closing structure 220, forming a sealed chamber together with the heat sink 201, allowing the first opening and closing structure 210 and the second opening and closing structure 220 to form a negative pressure area due to differential sliding. However, when it rains, the actuator of the electric push rod 401 drives the connecting push rod 402 to move towards the housing of the electric push rod 401, causing the two movable blades of the movable plate 403 to move closer to each other. This, in turn, drives the cover plate 405 to move outward from the heat dissipation device 200 via the driven rod 404, and the end of the cover plate 405 away from the middle of the heat sink 201 moves upward. Figure 3 The vertical direction within the heat sink 201. At this time, the first opening / closing structure 210 and the second opening / closing structure 220, located in the middle of the heat sink 201, are exposed to the external environment. For example... Figure 13As shown, both the first opening / closing structure 210 and the second opening / closing structure 220 include a water storage chamber 240 and multiple liquid holes 241. The liquid holes 241 are located at one end of the first scraper 231 and the second scraper 232 that contact the heat sink 201. Rainwater is collected inside the water storage chamber 240 through the cover plate 405 and flows evenly through the liquid holes 241 along with the sliding of the first opening / closing structure 210 and the second opening / closing structure 220, thereby cooling the heat sink 201. At the same time, the rainwater can also wash away impurities adhering to the heat sink 201. The washed-away impurities are discharged from the heat sink 201 through the sliding of the first opening / closing structure 210 and the second opening / closing structure 220, thus achieving a self-cleaning function.

[0064] In one embodiment, such as Figures 11 to 13 As shown, both the first opening / closing structure 210 and the second opening / closing structure 220 include a hinge assembly 250. Further, the hinge assembly 250 includes a first hinge rod 251 and a second hinge rod 252, which are hinged together. The first hinge rod 251 is hinged to the first scraper 231, and the second hinge rod 252 is hinged to the second scraper 232.

[0065] In one embodiment, such as Figures 2 to 7 As shown, the first opening / closing structure 210 and the second opening / closing structure 220 are connected by a linkage mechanism 300. Specifically, in the second mode, the linkage mechanism 300 drives the first opening / closing structure 210 and the second opening / closing structure 220 to slide, forming a dynamic turbulence structure. In the third mode, the linkage mechanism 300 drives the first opening / closing structure 210 and the second opening / closing structure 220 to slide, and simultaneously controls the first hinge rod 251 and the second hinge rod 252 to rotate the first scraper 231 and the second scraper 232 toward the heat sink 201, causing either the first opening / closing structure 210 or the second opening / closing structure 220 to unfold, forming a sealed chamber together with the cover plate 405 and the heat sink 201.

[0066] In addition, a rubber sheet 242 is provided on the side of the first scraper 231 and the second scraper 232 that contacts the heat sink 201. When the first scraper 231 and the second scraper 232 contact the heat sink 201, the rubber sheet 242 adheres to the surface of the heat sink 201 to ensure the sealing of the sealed chamber.

[0067] In one embodiment, such as Figures 2 to 7As shown, the linkage mechanism 300 includes a first wire 301, a second wire 302, a third wire 303, and a fourth wire 304. Specifically, the first wire 301 passes through all the second opening and closing structures 220 and is sequentially fixedly connected to the hinge positions of the first scraper 231 and the second scraper 232 of all the first opening and closing structures 210; the second wire 302 passes through all the second opening and closing structures 220 and is sequentially fixedly connected to the hinge positions of the first hinge rod 251 and the second hinge rod 252 of all the first opening and closing structures 210; the third wire 303 passes through all the first opening and closing structures 210 and is sequentially fixedly connected to the hinge positions of the first scraper 231 and the second scraper 232 of all the second opening and closing structures 220; the fourth wire 304 passes through all the first opening and closing structures 210 and is sequentially fixedly connected to the hinge positions of the first hinge rod 251 and the second hinge rod 252 of all the second opening and closing structures 220.

[0068] Furthermore, such as Figures 2 to 5 As shown, the first wire 301, the second wire 302, the third wire 303, and the fourth wire 304 are all loop coils connected end to end. Specifically, the first wire 301 and the second wire 302 drive the first opening and closing structure 210 to pass through all the gaps between the heat sinks 201 in sequence and then return to the initial position. Similarly, the third wire 303 and the fourth wire 304 drive the second opening and closing structure 220 to pass through all the gaps between the heat sinks 201 in sequence and then return to the initial position. This allows the first opening and closing structure 210 and the second opening and closing structure 220 to slide cyclically between the heat sinks 201, thereby ensuring the continuous operation of heat dissipation.

[0069] In addition, the linkage mechanism 300 also includes a first guide wheel 311, a second guide wheel 312, a third guide wheel 313, and a fourth guide wheel 314. For example... Figure 5 As shown, the linkage mechanism 300 also includes a first motor 321, a second motor 322, a third motor 323, a fourth motor 324 and multiple gear structures 341, as well as a first drive shaft 331, a second drive shaft 332, a third drive shaft 333, a fourth drive shaft 334 and multiple rotating shafts 340.

[0070] Specifically, the first motor 321 provides power to the first drive shaft 331 via a gear structure 341. The first guide wheel 311 is fixedly connected to the first drive shaft 331, driving the first guide wire 301 to rotate. The second guide wheel 312, third guide wheel 313, and fourth guide wheel 314 are rotatably connected to the first drive shaft 331. Similarly, the second motor 322 provides power to the second drive shaft 332 via the gear structure 341. The second guide wheel 312 is fixedly connected to the second drive shaft 332, driving the second guide wire 302 to rotate. The first guide wheel 311, third guide wheel 313, and fourth guide wheel 314 are rotatably connected to the second drive shaft 332. The third motor 323 provides power to the third drive shaft 333 via a gear structure 341. The third guide wheel 313 is fixedly connected to the third drive shaft 333, and drives the third guide wire 303 to rotate. The first guide wheel 311, the second guide wheel 312, and the fourth guide wheel 314 are rotatably connected to the third drive shaft 333. The fourth motor 324 provides power to the fourth drive shaft 334 via a gear structure 341. The fourth guide wheel 314 is fixedly connected to the fourth drive shaft 334, and drives the fourth guide wire 304 to rotate. The first guide wheel 311, the second guide wheel 312, and the third guide wheel 313 are rotatably connected to the fourth drive shaft 334. It is worth noting that the first guide wheel 311, the second guide wheel 312, the third guide wheel 313, and the fourth guide wheel 314 are all rotatably connected to all the rotating shafts 340.

[0071] When the heat dissipation device 200 is in the first stage of the third mode, the second motor 322 and the fourth motor 324 are driven first. The second wire 302 drives the first scraper 231 and the second scraper 232 to rotate through the first hinge rod 251 and the second hinge rod 252 of the first opening and closing structure 210, so that the first opening and closing structure 210 unfolds and adheres to the surface of the heat sink 201. The fourth wire 304 drives the first scraper 231 and the second scraper 232 to rotate through the first hinge rod 251 and the second hinge rod 252 of the second opening and closing structure 220, so that the second opening and closing structure 220 unfolds and adheres to the surface of the heat sink 201, thereby forming a sealed chamber between the first opening and closing structure 210, the second opening and closing structure 220, the cover plate 405 and the heat sink 201. Then, the rotational speeds of the first motor 321 and the second motor 322 are made greater than the rotational speeds of the third motor 323 and the fourth motor 324, thereby making the rotational speeds of the first wire 301 and the second wire 302 greater than the rotational speeds of the third wire 303 and the fourth wire 304, and making the sliding speed of the first opening and closing structure 210 greater than the sliding speed of the second opening and closing structure 220. As a result, the pressure in the sealed chamber is reduced, forming a negative pressure environment, which in turn reduces the air temperature in the sealed chamber and optimizes the heat dissipation effect.

[0072] When the heat dissipation device 200 is in the second stage of the third mode, similarly, the second motor 322 and the fourth motor 324 are first driven to unfold the first opening and closing structure 210 and the second opening and closing structure 220 and fit against the surface of the heat sink 201, forming a sealed chamber between the cover plate 405 and the heat sink 201. Next, the rotational speeds of the third motor 323 and the fourth motor 324 are increased compared to the rotational speeds of the first motor 321 and the second motor 322, resulting in the rotational speeds of the third wire 303 and the fourth wire 304 being greater than the rotational speeds of the first wire 301 and the second wire 302. This, in turn, causes the sliding speed of the second opening and closing structure 220 to be greater than the sliding speed of the first opening and closing structure 210. Therefore, the pressure in the sealed chamber decreases, creating a negative pressure environment, thereby reducing the air temperature inside the sealed chamber and optimizing the heat dissipation effect.

[0073] Understandably, to ensure the stability of the first opening and closing structure 210 and the second opening and closing structure 220, the linkage mechanism 300 can be configured into two sets, such as... Figure 2 As shown, they are respectively located at the upper and lower ends of the first opening and closing structure 210 and the second opening and closing structure 220, that is... Figure 2 The vertical direction within. Furthermore, to ensure that the first opening / closing structure 210 and the second opening / closing structure 220 do not interfere with each other during deployment, the hinge assembly 250 of the first opening / closing structure 210 is closer to the center of the heat sink 201 than the hinge assembly 250 of the second opening / closing structure 220. The hinge assemblies 250 of the two structures are not on the same plane, so that when the heat sink 200 is in the third mode, the rotation and sliding of the first scraper 231 and the second scraper 232 of the first opening / closing structure 210 and the second opening / closing structure 220 do not interfere with each other, thereby ensuring smooth movement.

[0074] It is worth noting that, since the first opening and closing structure 210 and the second opening and closing structure 220 pass through the rotation shaft 340, the first drive shaft 331, the second drive shaft 332, the third drive shaft 333, and the fourth drive shaft 334 during sliding, this may cause obstruction of movement. Therefore, as Figures 2 to 13 As shown, the heat dissipation device 200 also includes a first support frame 202 and a second support frame 203. The rotating shaft 340 is slidably connected to the first support frame 202 via a slider 343, and an elastic component 344 is provided on the slider 343. When the first opening / closing structure 210 or the second opening / closing structure 220 passes the rotating shaft 340, the rotating shaft 340 is compressed and slides along the first support frame 202, compressing the elastic component 344. During this process, the first opening / closing structure 210 or the second opening / closing structure 220 is forced to gradually close between the guide wheel and the wire, minimizing resistance and damage to components, and ensuring the smooth passage of the first opening / closing structure 210 or the second opening / closing structure 220.

[0075] In addition, such as Figure 14As shown, the first drive shaft 331 is slidably connected to the second support frame 203 via a gear slider 342, and an elastic component 344 is also provided on the gear slider 342. When the first opening / closing structure 210 or the second opening / closing structure 220 passes the first drive shaft 331, the first drive shaft 331 will be compressed and slide along the second support frame 203, and the elastic component 344 will be compressed. During this process, the first opening / closing structure 210 or the second opening / closing structure 220 will be forced to gradually close between the guide wheel and the guide wire, minimizing resistance and damage to components, and ensuring the smooth passage of the first opening / closing structure 210 or the second opening / closing structure 220. After the first opening / closing structure 210 or the second opening / closing structure 220 passes, the elastic force of the elastic component 344 will reset the rotating shaft 340 and the first drive shaft 331.

[0076] It is understandable that when the first opening and closing structure 210 and the second opening and closing structure 220 pass through the second drive shaft 332, the third drive shaft 333 and the fourth drive shaft 334, their working process is the same as that of the first drive shaft 331.
