Description
Technical Field
[0001] The present invention relates to the technical field of electronic equipment, and in particular to a semiconductor field effect tube heat dissipation structure and method. Background Art
[0002] Semiconductor field-effect transistors, particularly metal-oxide-semiconductor field-effect transistors (MOS transistors), play a vital role in modern electronic devices. Their advantages include high input resistance, low noise, low power consumption, wide dynamic range, ease of integration, no secondary breakdown, and a wide safe operating area. Consequently, they are widely used in electronic devices such as microprocessors, memory, and logic circuits.
[0003] During the operation of semiconductor field-effect transistors, a certain amount of heat will be generated due to the passage of current and the action of the electric field. If the heat cannot be dissipated in time, the temperature of the device will rise, which will in turn affect its performance and reliability. Especially in high-frequency and high-power application scenarios, the heat dissipation problem is particularly prominent. Therefore, as the performance of electronic equipment continues to improve, higher requirements are also placed on the heat dissipation performance of semiconductor field-effect transistors.
[0004] However, most traditional semiconductor field-effect tubes rely on the design of heat sinks to dissipate internal hot air. However, this heat dissipation method is inefficient and cannot complete the internal heat dissipation task in a timely and effective manner. Even more disadvantageously, during long-term use, a large amount of dust often accumulates on the outer surface of the heat sink, causing the heat sink to become clogged, thereby further weakening its heat dissipation performance. This clogging phenomenon will prevent the heat inside the semiconductor field-effect tube from being smoothly discharged, and may eventually damage the internal electronic components due to excessively high temperatures.

[0016] A semiconductor field effect tube heat dissipation method is applied to the above-mentioned semiconductor field effect tube heat dissipation structure, comprising the following steps:
[0017] S1. When the MOSFET begins operating, the micro-water pump starts simultaneously, pumping cooling liquid from one end of the micro-water pump into the heat absorption tube. The cooling liquid flows along the serpentine path of the heat absorption tube and absorbs heat from the MOSFET through the heat absorption plate.
[0018] S2. As the cooling liquid flows through the middle of the absorber tube, it encounters the deceleration module. The baffles and baffles at the upper and lower ends of the module guide the cooling liquid's flow, causing it to flow slowly through the circulation and return grooves. Simultaneously, undulating blocks on the upper end of the baffles and the center of the inner bottom of the absorber tube alter the cooling liquid's flow path, causing it to flow in a wavy pattern.
[0019] S3. After fully absorbing heat, the cooling liquid flows out of the heat absorption tube and into the micro-condenser. There, the cooling liquid is condensed, and the released heat is removed by the external cooling system. The condensed cooling liquid is then drawn back into the micro-water pump, forming a closed-loop circulation system that continuously dissipates heat from the semiconductor field-effect transistor.
[0020] S4. A spoiler assembly is provided on the inner top surface of the semiconductor field effect tube body. When the heat inside the semiconductor field effect tube body is high, the spoiler assembly starts to work, and the heat-expandable airbag expands when the temperature rises, pushing the connecting ring to move toward the side of the transfer tube. As the airbag expands, the air in the sealing sleeve is squeezed into the rotating tube through the transfer tube. The rotating tube can be engaged and rotated relative to the transfer tube under the action of the clamping block, which enables the elbow nozzle to spray air in different directions to form a spoiler effect to increase the heat absorption effect of the heat absorption tube.
[0021] Beneficial effects of the present invention:
[0022] 1. The semiconductor field-effect tube heat dissipation structure achieves efficient heat dissipation through built-in heat dissipation components. Specifically, the cooling liquid filled in the heat absorption tube can effectively absorb and take away the heat inside the semiconductor field-effect tube body. The heat absorption tube is designed in a serpentine shape and is equipped with multiple evenly spaced heat absorption fins, which increases the heat exchange area and further improves the heat dissipation efficiency. In addition, the application of the speed reduction module slows down the circulation speed of the coolant in the heat absorption tube, prolongs the heat exchange time between the coolant and the heat absorption tube and the heat absorption fins, thereby ensuring more sufficient heat transfer. At the same time, the spoiler component set on the inner top surface accelerates the circulation of hot air inside the semiconductor field-effect tube, contributes to the heat absorption effect of the heat absorption tube, and further improves the overall heat dissipation performance. The combined effect of this series of designs significantly improves the heat dissipation effect of the semiconductor field-effect tube, ensures its stable operation and extends its service life.
[0023] 2. This semiconductor field effect tube heat dissipation method significantly improves the thermal management efficiency of the semiconductor field effect tube. When the semiconductor field effect tube is working, the micro water pump starts immediately to pump the cooling liquid into the heat absorption tube, efficiently absorbs the heat in the tube along the serpentine path, and effectively transfers the internal heat of the semiconductor field effect tube through the heat absorption sheet. When the cooling liquid flows through the middle of the heat absorption tube, the ingenious design of the speed reduction module slows down the liquid flow rate. Through the guidance of the partition, the baffle block and the undulating block, a wavy flow path is formed, which further improves the heat exchange efficiency. Subsequently, the cooling liquid after absorbing heat enters the micro condenser and is condensed. The heat released by condensation is taken away by the external cooling system, and the condensate is re-absorbed by the micro water pump to form a closed-loop circulation, ensuring a continuous and stable heat dissipation effect. In addition, the built-in spoiler component automatically starts when the heat inside the semiconductor field effect tube is high, and promotes air flow through the expansion of the airbag, and uses the curved pipe nozzle to spray air in different directions to form a turbulent flow, which not only accelerates the circulation of hot air inside the semiconductor field effect tube, but also significantly enhances the heat absorption effect of the heat absorption tube, thereby achieving more efficient and comprehensive heat dissipation, extending the service life of the semiconductor field effect tube, and improving its working performance.

[0036] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to specific embodiments.
[0037] It should be noted that, unless otherwise defined, the technical or scientific terms used in the present invention should have the usual meanings understood by people with ordinary skills in the field to which the present invention belongs.

"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.
[0038] like Figures 1 to 9 As shown, a semiconductor field effect tube heat dissipation structure includes a semiconductor field effect tube body 1, a heat dissipation component is provided inside the semiconductor field effect tube body 1, and the heat dissipation component is used to absorb heat inside the semiconductor field effect tube body 1. The heat dissipation component includes a heat absorption tube 4, and a cooling liquid is provided inside the heat absorption tube 4. The heat absorption tube 4 is serpentine and both ends pass through the outside of the semiconductor field effect tube body 1. A plurality of heat absorption fins 5 are evenly spaced and fixedly connected to the middle of the heat absorption tube 4. A speed reduction module is provided inside the heat absorption tube 4, and the speed reduction module is used to reduce the circulation speed of the coolant inside the heat absorption tube 4. A spoiler component is provided on the inner top surface of the semiconductor field effect tube body 1, and the spoiler component is used to increase the circulation speed of the internal hot air.
[0039] This heat dissipation structure achieves efficient heat dissipation through built-in heat dissipation components. Specifically, the cooling liquid filled in the heat absorption tube 4 can effectively absorb and take away the heat inside the semiconductor field effect tube body 1, and the heat absorption tube 4 is designed in a serpentine shape and is equipped with multiple evenly spaced heat absorption plates 5, which increases the heat exchange area and further improves the heat dissipation efficiency. In addition, the application of the speed reduction module slows down the circulation speed of the coolant in the heat absorption tube 4, extends the heat exchange time between the coolant and the heat absorption tube 4 and the heat absorption plates 5, thereby ensuring more sufficient heat transfer. At the same time, the spoiler component arranged on the inner top surface accelerates the circulation of hot air inside the semiconductor field effect tube, contributes to the heat absorption effect of the heat absorption tube 4, and further improves the overall heat dissipation performance. The combined effect of this series of designs significantly improves the heat dissipation effect of the semiconductor field effect tube, ensures its stable operation and extends its service life.
[0040] Further, such as Figure 1 As shown, one end of the heat absorption tube 4 is fixedly connected to the micro water pump 2, the end of the heat absorption tube 4 away from the micro water pump 2 is fixedly connected to the micro condenser 3, and the end of the micro condenser 3 away from the heat absorption tube 4 is fixedly connected to the micro water pump 2;
[0041] When the semiconductor field effect transistor body 1 starts working, the micro water pump 2 starts, driving the cooling liquid to flow in from the end of the heat absorption tube 4 close to the micro water pump 2. The cooling liquid flows along the serpentine path of the heat absorption tube 4, and in this process absorbs the heat inside the semiconductor field effect tube body 1 through the heat absorption sheet 5. After sufficient heat absorption, the cooling liquid then flows out of the heat absorption tube 4 and enters the micro condenser 3. In the micro condenser 3, the cooling liquid is cooled, thereby releasing the heat previously absorbed. The condensed cooling liquid is again sucked into the micro water pump 2 to form a closed loop cycle, and enters the heat absorption tube 4 again to continue absorbing heat. This cycle continues, continuously taking away the heat inside the semiconductor field effect tube body 1 and dissipating it to the external environment.
[0042] Further, such as Figures 7 to 9 As shown, the deceleration module includes a baffle 17 fixedly connected to the middle part of the heat absorption tube 4, and the upper and lower ends of the baffle 17 are fixedly connected to the baffle block 16. The interior of the heat absorption tube 4 is provided with a circulation groove 21 for circulating the cooling liquid in the middle of the upper and lower ends of the baffle 17. A plurality of reflux grooves 20 are evenly spaced on one side of the baffle block 16 close to the circulation groove 21. One end of the reflux groove 20 is connected to the circulation groove 21, and the other end is configured to be concave semicircular to achieve a reflux effect. The middle part of the upper end surface of the baffle 17 and the middle part of the inner bottom surface of the heat absorption tube 4 are fixedly connected with an undulating block 18. The upper end of the undulating block 18 is wavy to change the flow path of the cooling liquid.
[0043] A partition 17 is fixedly connected to the middle of the inner part of the heat absorption tube 4. This partition 17 divides the heat absorption tube 4 into two upper and lower areas. The upper and lower ends of the partition 17 are fixedly connected to the baffle blocks 16. The function of these baffle blocks 16 is to guide the flow direction of the cooling liquid. In the middle of the upper and lower ends of the partition 17, a flow groove 21 is opened on the heat absorption tube 4. These grooves allow the cooling liquid to flow between the upper and lower sides of the partition 17. However, the flow of the cooling liquid does not simply pass through the flow groove 21. On the side of the baffle block 16 close to the flow groove 21, a plurality of reflux grooves 20 are evenly spaced. One end of these reflux grooves 20 is connected to the flow groove 21, and the other end is designed to be concave semicircular. This design allows the cooling liquid to reflux along the concave semicircular path of the reflux groove 20 after flowing through the flow groove 21, thereby slowing down the flow rate of the cooling liquid. In addition, in order to further To enhance the deceleration effect and improve the heat exchange efficiency, the middle part of the upper end surface of the partition 17 and the middle part of the inner bottom surface of the heat absorption tube 4 are fixedly connected with the undulating blocks 18. The upper ends of these undulating blocks 18 are designed to be wavy. When the cooling liquid flows through these undulating blocks 18, its flow path will be continuously changed, causing the cooling liquid to continuously impact the inner wall of the heat absorption tube 4 inside the heat absorption tube 4. This impact not only further reduces the flow speed of the cooling liquid, but also increases the contact area and contact time between the cooling liquid and the inner wall of the heat absorption tube 4 and the heat absorption plate 5, thereby improving the heat exchange efficiency. In summary, the deceleration module effectively reduces the circulation speed of the cooling liquid inside the heat absorption tube 4 through the combined action of the baffle block 16, the reflux groove 20 and the undulating blocks 18, and increases the heat exchange area and contact time between the cooling liquid and the inner wall of the heat absorption tube 4 and the heat absorption plate 5, thereby improving the heat dissipation efficiency of the entire heat dissipation structure.
[0044] Further, such as Figures 4 to 6As shown, the spoiler assembly includes a sealing sleeve 8, one side of the middle of the inner wall of the sealing sleeve 8 is fixedly connected to a limiting plate 13, one end face of the limiting plate 13 is fixedly connected to an airbag 12 that can be expanded by heat, and one end of the airbag 12 away from the limiting plate 13 is fixedly connected to a connecting ring 22, and the upper and lower ends of the end face of the connecting ring 22 away from the airbag 12 are fixedly connected to telescopic spring seats 19, and the ends of the two telescopic spring seats 19 away from the airbag 12 are fixedly connected to the inner wall of the sealing sleeve 8, and the outer wall of the sealing sleeve 8 on one side of the limiting plate 13 is evenly spaced with a plurality of through holes 9, and the outer side of the middle of the limiting plate 13 is evenly spaced with a plurality of vents 14, and the middle of one end face of the sealing sleeve 8 is fixedly connected to the inner wall of the sealing sleeve 8. A transfer tube 6 is fixedly connected, and the transfer tube 6 is U-shaped. The diameter ratio of the transfer tube 6 to the sealing sleeve 8 is 1:8. A plurality of mounting seats 7 are fixedly connected to the upper end of the transfer tube 6 at even intervals. The upper ends of the plurality of mounting seats 7 are fixedly connected to the semiconductor field effect tube body 1. The end of the transfer tube 6 away from the sealing sleeve 8 is engaged and rotatably connected to the rotating tube 10. A clamping block 15 is fixedly connected to the outer side of the upper end surface of the rotating tube 10. The rotating tube 10 is engaged and rotatably connected to the rotating tube 10 through the clamping block 15. The lower end of the rotating tube 10 is in a closed state. A plurality of elbow nozzles 11 are fixedly connected to the outer wall of the rotating tube 10 at even intervals. The elbow nozzle 11 is L-shaped. The rotating tube 10 is connected to the transfer tube 6;
[0045] The spoiler assembly mainly consists of a sealing sleeve 8 and a series of structures inside it. These structures work together in the internal space of the semiconductor field effect transistor body 1 to accelerate the circulation of hot air and enhance the heat absorption effect of the heat absorption tube 4. When the semiconductor field effect transistor body 1 is working, heat is generated inside it, causing the temperature to rise. At this time, the heated expandable airbag 12 in the sealing sleeve 8 will expand due to the temperature increase. When the airbag 12 expands due to heat, it will push the connecting ring 22 to slide along the inner wall of the sealing sleeve 8. This sliding action not only compresses the telescopic spring seat 19, but also causes the restricted air inside the sealing sleeve 8 to be squeezed into the transfer tube 6 through the vent holes 14 on the limiting plate 13 and the through holes 9 on the outer wall of the sleeve. Due to the design of the diameter ratio of the transfer tube 6 and the sealing sleeve 8, the air can be effectively concentrated and guided to the rotating tube 10. The rotating tube 10 is flexibly connected by the clamping block 15. Its lower end is closed and the outer wall is evenly distributed with L-shaped elbow nozzles 11. As the air flows from the transfer tube 6 into the rotating tube 10, it is finally ejected through the elbow nozzles 11. This turbulent effect not only accelerates the circulation speed of the hot air inside the semiconductor field effect transistor body 1, but also helps to distribute the heat more evenly throughout the space, thereby improving the heat absorption efficiency of the heat absorption tube 4. Under the action of the deceleration module, the cooling liquid inside the heat absorption tube 4 can more fully exchange heat with the inside of the semiconductor field effect transistor body 1, thereby achieving a more efficient heat dissipation effect.
[0046] An embodiment of the present invention further provides a semiconductor field effect tube heat dissipation method, which is applied to the above-mentioned semiconductor field effect tube heat dissipation structure, and includes the following steps:
[0047] S1. When MOSFET body 1 begins operating, micro-water pump 2 starts simultaneously, pumping cooling liquid from one end of micro-water pump 2 into heat absorption tube 4. The cooling liquid flows along the serpentine path of heat absorption tube 4 and absorbs heat from MOSFET body 1 through heat absorption sheet 5.
[0048] S2. As the cooling liquid flows through the middle of the heat absorbing tube 4, it encounters the deceleration module. The baffle 17 and its upper and lower baffles 16 guide the cooling liquid's flow, causing it to flow slowly through the circulation groove 21 and the return groove 20. Simultaneously, the undulating block 18 on the upper surface of the baffle 17 and the middle of the inner bottom surface of the heat absorbing tube 4 alters the cooling liquid's flow path, causing it to flow in a wavy pattern.
[0049] S3. After sufficient heat absorption, the cooling liquid flows out of the heat absorption tube 4 and enters the micro-condenser 3. In the micro-condenser, the cooling liquid is condensed, and the released heat is removed by the external cooling system. The condensed cooling liquid is then sucked back into the micro-water pump 2, forming a closed-loop circulation, continuously dissipating heat from the semiconductor field-effect transistor body 1.
[0050] S4. A spoiler assembly is provided on the inner top surface of the semiconductor field effect transistor body 1. When the heat inside the semiconductor field effect transistor body 1 is high, the spoiler assembly starts to work, and the heat-expandable airbag 12 expands when the temperature rises, pushing the connecting ring 22 to move toward the side of the transfer tube 6. As the airbag 12 expands, the air in the sealing sleeve 8 is squeezed into the rotating tube 10 through the transfer tube 6. The rotating tube 10 can be engaged and rotated relative to the transfer tube 6 under the action of the clamping block 15, which enables the elbow nozzle 11 to spray air in different directions to form a spoiler effect to increase the heat absorption effect of the heat absorption tube 4.
[0051] The above-mentioned heat dissipation method is adopted to significantly improve the thermal management efficiency of the semiconductor field effect tube. When the semiconductor field effect tube is working, the micro water pump 2 is immediately started to pump the cooling liquid into the heat absorption tube 4, efficiently absorbing the heat in the tube along the serpentine path, and effectively transferring the internal heat of the semiconductor field effect tube through the heat absorption sheet 5. When the cooling liquid flows through the middle of the heat absorption tube 4, the ingenious design of the speed reduction module slows down the liquid flow rate. Through the guidance of the partition 17, the baffle block 16 and the undulating block 18, a wavy flow path is formed, which further improves the heat exchange efficiency. Subsequently, the cooling liquid after absorbing heat enters the micro condenser 3 and is condensed. The heat released by condensation is taken away by the external heat dissipation system, and the condensate is re-absorbed by the micro water pump 2 to form a closed-loop circulation, ensuring a continuous and stable heat dissipation effect. In addition, the built-in turbulence component is automatically activated when the heat inside the semiconductor field effect tube is high, and the air flow is promoted by the expansion of the airbag 12. The air is sprayed in different directions by the curved nozzle 11 to form a turbulence, which not only accelerates the circulation of hot air inside the semiconductor field effect tube, but also significantly enhances the heat absorption effect of the heat absorption tube 4, thereby achieving more efficient and comprehensive heat dissipation, extending the service life of the semiconductor field effect tube, and improving its working performance.

7. The semiconductor field effect tube heat dissipation structure according to claim 6, characterized in that: One end of the transfer tube (6) away from the sealing sleeve (8) is engaged and rotatably connected to a rotating tube (10), a clamping block (15) is fixedly connected to the outer side of the upper end surface of the rotating tube (10), the rotating tube (10) is engaged and rotatably connected to the rotating tube (10) via the clamping block (15), the lower end of the rotating tube (10) is in a closed state, and the outer wall of the rotating tube (10) is evenly spaced and fixedly connected to a plurality of elbow nozzles (11), the elbow nozzles (11) are L-shaped, and the rotating tube (10) is connected to the transfer tube (6).
8. A semiconductor field effect tube heat dissipation method, applied to the semiconductor field effect tube heat dissipation structure according to any one of claims 1 to 7, characterized in that: The following steps are involved: S1. When the semiconductor field effect tube body (1) starts to work, the micro water pump (2) starts synchronously, pumping the cooling liquid from one end of the micro water pump (2) into the heat absorption tube (4). The cooling liquid flows along the serpentine path of the heat absorption tube (4) and absorbs the heat inside the semiconductor field effect tube body (1) through the heat absorption plate (5); S2. When the cooling liquid flows through the middle of the heat absorbing tube (4), it encounters the deceleration module. The baffle (17) in the deceleration module and the baffle blocks (16) at the upper and lower ends thereof guide the flow direction of the cooling liquid, causing it to flow slowly through the flow groove (21) and the reflux groove (20). At the same time, the undulating blocks (18) on the upper end surface of the baffle (17) and the middle of the inner bottom surface of the heat absorbing tube (4) change the flow path of the cooling liquid, causing it to flow in a wavy shape. S3. The cooling liquid that has fully absorbed heat flows out of the heat absorbing tube (4) and enters the micro condenser (3). In the micro condenser, the cooling liquid is condensed, and the released heat is taken away by the external heat dissipation system. The condensed cooling liquid is sucked into the micro water pump (2) again, forming a closed loop circulation, which continuously dissipates heat for the semiconductor field effect tube body (1); S4. A turbulence component is provided on the inner top surface of the semiconductor field effect tube body (1). When the heat inside the semiconductor field effect tube body (1) is high, the turbulence component starts to work, and the heat-expandable airbag (12) expands when the temperature rises, pushing the connecting ring (22) to move toward the side of the transfer tube (6). As the airbag (12) expands, the air in the sealing sleeve (8) is squeezed into the rotating tube (10) through the transfer tube (6). The rotating tube (10) is engaged and rotated relative to the transfer tube (6) under the action of the clamping block (15), which enables the elbow nozzle (11) to spray air in different directions to form a turbulence effect to increase the heat absorption effect of the heat absorption tube (4).
