Description

Technical Field

[0001] This invention relates to a high-efficiency, lightweight heat exchanger, and more particularly to a high-efficiency, lightweight heat exchanger for low-altitude aircraft power supply, applied in the field of aircraft thermal management technology. Background Technology

[0002] Electronic components in low-altitude aircraft generate significant heat during operation, particularly the aircraft's power supply. Independent air ducts are emerging as a revolutionary direction for heat dissipation design of aircraft electronic components in the low-altitude economy. Through the deep integration of customized airflow paths and intelligent control technology, they provide efficient thermal management solutions for lightweight, high-power-density aircraft electronic systems. This design abandons traditional distributed heat dissipation structures, instead constructing a directional airflow system highly coupled to the heat sources of electronic components. Utilizing aerodynamic optimization and breakthroughs in materials science, it achieves precise airflow guidance and rapid heat dissipation.

[0003] Chinese patent CN202322462636.5 discloses "An Easy-to-Install UAV Battery Heatsink," which uses a water cooler as the core component of the heat dissipation system. The water cooler transfers the cool air generated during the circulation of the circulating fluid in the circulation pipe to the partition plate to absorb the heat released by the battery. A heat exchanger is also included to absorb heat from the battery when it overheats, using the flow of a cooling medium (air, liquid, etc.). Chinese patent CN202010939600.X discloses "A UAV with a Circuit Board Heat Dissipation Structure." This structure surrounds the circuit board by placing it between two heat conduction plates in the heat dissipation component. The heat generated by the circuit board is quickly and evenly transferred to the top and bottom plates of the heat dissipation component through the heat conduction plates. The continuous flow of the cooling medium in the circulation channel exchanges heat with the circuit board, thus carrying away the heat. Compared to traditional cooling fan structures, surrounding the circuit board and using the circulating flow of the cooling medium provides comprehensive and more uniform heat dissipation.

[0004] In existing technologies, air-cooled heat sinks mostly use fins of a single shape, such as... Figure 3 As shown, uneven local heat dissipation or excessive flow resistance can lead to this problem. Most existing heat exchangers use plate fins, which have very low flow resistance but limited heat exchange performance and are gradually failing to meet heat dissipation requirements. In order to further reduce weight, it is imperative to develop heat exchange structures with high heat transfer performance and low flow resistance. Summary of the Invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that most existing heat exchangers adopt plate fins, which have very small flow resistance, but their heat exchange performance is limited and they are gradually unable to meet the heat dissipation requirements.

[0006] To address the aforementioned problems, this invention provides a high-efficiency, lightweight heat exchanger for low-altitude aircraft power supplies, comprising an air-cooled heat dissipation channel, a heat exchange recess at the bottom of the air-cooled heat dissipation channel, and airflow inlet and outlet at both ends of the air-cooled heat dissipation channel, respectively. Inlet guide ribs and outlet guide ribs are fixedly connected inside the airflow inlet and outlet, respectively. A rib module is fixedly connected between the inlet guide ribs and the outlet guide ribs. A column rib module is fixedly connected inside the air-cooled heat dissipation channel, with the rib module and column rib module alternating.

[0007] The rib module includes straight ribs and wavy ribs, and the column rib module includes cylindrical ribs, semi-circular ribs and semi-circular triangular ribs. Straight ribs and wavy ribs can be combined individually or freely with cylindrical ribs, semi-circular ribs and semi-circular triangular ribs.

[0008] The top and bottom of the wavy ribs are slidably connected to the inner wall of the air-cooled heat dissipation channel, and the wavy ribs are made of titanium alloy. Temperature control targets are fixedly distributed in a matrix between the air-cooled heat dissipation channel and the heat exchange concave area. The top of the temperature control targets is fixedly connected to the inner concave part of the wavy ribs with connecting ribs made of shape memory alloy.

[0009] In the aforementioned high-efficiency lightweight heat exchanger for low-altitude aircraft power supply, a suitable combination of finned modules and column finned modules is selected for the air-cooled heat dissipation channel according to the operating environment. This facilitates a larger heat exchange surface area and effectively improves heat exchange efficiency by turbulent fluid, thereby effectively improving the heat dissipation effect of the aircraft.

[0010] As a further improvement of this application, the temperature control target body has a movable groove in the middle that communicates with the heat exchange recess. The temperature control target body is made of aerogel material. The temperature control target body made of aerogel material has low thermal conductivity, thereby achieving the heat insulation effect of the temperature control target body.

[0011] As a further improvement of this application, the top and bottom of the connecting rib are both curved, and a heat insulation sleeve is wrapped between the top of the connecting rib and the top of the temperature control body. The movable groove is sleeved with the bottom curved end of the connecting rib. The connecting rib, made of shape memory alloy material, bends and changes in the curved position, thereby using the change in the bending amplitude of the connecting rib to drive the deformation of the wavy rib, changing the local bending amplitude of the wavy rib, thereby effectively enhancing the fluid disturbance capability of the area and effectively improving the heat exchange capability of the area. The heat insulation sleeve effectively improves the heat insulation capability of the connecting rib, thereby extending the deformation state time of the connecting rib, that is, extending the time of improving the heat exchange capability of the area.

[0012] As a further improvement of this application, a sealing plate is fixedly connected to the lower opening of the movable groove. The bottom arc-shaped end of the connecting rib contacts and corresponds to the sealing plate. The sealing plate is made of aluminum alloy. The sealing plate is used to seal the lower part of the movable groove, effectively preventing the fluid inside the air-cooled heat dissipation channel from leaking into the heat exchange recess. Furthermore, the heat conduction through the contact between the connecting rib and the sealing plate facilitates the thermal deformation of the connecting rib. After the connecting rib deforms, the contact between the connecting rib and the sealing plate is broken, thereby effectively reducing the heat dissipation of the connecting rib and extending the deformation time of the connecting rib.

[0013] As another improvement of this application, the lower edge of the wavy fin is provided with a content groove, and a thermally conductive silicone strip is fixedly embedded inside the content groove. The thermally conductive silicone strip is slidably connected to the inner wall of the air-cooled heat dissipation channel, and the heat exchange capacity between the wavy fin and the inner wall of the air-cooled heat dissipation channel is effectively improved by using the thermally conductive silicone strip.

[0014] As a further improvement to this application, the thermally conductive silicone strip is fixedly connected with pads at equal intervals in the middle. The two ends of the pads are fixedly connected to the inner wall of the air-cooling heat dissipation channel. The thermally conductive silicone strip is buffered and fixed to the air-cooling heat dissipation channel through the pads, thus retaining a certain range of motion of the thermally conductive silicone strip.

[0015] As a further improvement to this application, both ends of the pad are provided with arched buffer portions, and the pad is made of elastic plastic. The pad can bend through the arched buffer portions to achieve the pad's adaptation to the movement and buffering of the thermally conductive silicone strip.

[0016] As another improvement of this application, a locking hole is provided at the bottom of the arched buffer section near the thermal conductive silicone strip. A locking screw is inserted into the locking hole. The bottom of the locking screw is threaded to the inner wall of the air-cooling heat dissipation channel, and the top of the locking screw is in contact with the side of the wavy rib. The air-cooling heat dissipation channel is connected by the locking screw through the locking hole, thereby fixing the displacement capability of the wavy rib in this area, thus providing a force support point for adjusting the bending amplitude of the wavy rib.

[0017] In summary, the high-efficiency lightweight heat exchanger proposed in this invention selects appropriate combinations of finned and column finned modules based on the operating environment, effectively providing a larger heat exchange surface area for the power system. It also effectively improves heat exchange efficiency by turbulent fluid flow, ensuring efficient heat dissipation for the aircraft's power system under prolonged high-power output. Through optimized structural design, the weight of the heat exchanger is minimized, ensuring better payload and endurance for the aircraft. When using wavy fins in the finned modules, localized temperature monitoring of the heat exchange concave area is conducted using a temperature control probe. When the temperature in this area triggers the thermal deformation of the connecting ribs, the thermal deformation of the connecting ribs pushes the concave portion of the wavy fins to further bend, thereby enhancing the irregularity of the wavy fins in this area, effectively increasing the turbulent flow disturbance capability of the fluid, and locally improving the heat exchange capacity of this area. Subsequently, after the temperature decreases, the wavy fins automatically recover their shape. Attached Figure Description

[0033] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0034] First implementation method:

[0035] Figures 1 to 8 The diagram shows a high-efficiency lightweight heat exchanger for a low-altitude aircraft power supply, comprising an air-cooled heat dissipation channel 1, a heat exchange recess 101 at the bottom of the air-cooled heat dissipation channel 1, and airflow inlet 102 and airflow outlet 103 respectively at both ends of the air-cooled heat dissipation channel 1. Inlet guide ribs 104 and outlet guide ribs 105 are fixedly connected inside the airflow inlet 102 and the airflow outlet 103 respectively. A rib module is fixedly connected between the inlet guide ribs 104 and the outlet guide ribs 105. A column rib module is fixedly connected inside the air-cooled heat dissipation channel 1, with the rib module and column rib module alternating.

[0036] The rib module includes a straight rib 201 and a wavy rib 202, and the column rib module includes a cylindrical rib 301, a semi-circular rib 302 and a semi-circular triangular rib 303. The straight rib 201 and the wavy rib 202 can be combined individually or freely with the cylindrical rib 301, the semi-circular rib 302 and the semi-circular triangular rib 303.

[0037] This high-efficiency, lightweight heat exchanger, based on the operating environment, selects a suitable combination of finned and column-finned modules in its air-cooled heat dissipation channel 1. This effectively provides a larger heat exchange surface area. Especially between the column-finned modules, the fluid velocity slows down and flow irregularities occur, generating vortices. These vortices greatly enhance the fluid's heat exchange capacity. By enhancing fluid turbulence, the vortices allow heat to be transferred more quickly from the cylindrical surface to the fluid, absorbing the heat generated by the internal equipment. At the same time, the gas carries away more heat during flow and effectively improves heat exchange efficiency by disturbing the fluid. This ensures that the aircraft's power system provides efficient heat dissipation under long-term high-power output conditions. Through optimized structural design, the weight of the heat exchanger is reduced to the greatest extent possible, ensuring that the aircraft has better load capacity and endurance.

[0038] The key to the technical solution of this invention lies in optimizing the combination of the fin module and the column fin module in the air-cooled heat dissipation channel 1 to improve the heat dissipation efficiency of the heat exchanger, reduce the weight of the aircraft, and ensure the temperature control stability of the aircraft power system during operation.

[0039] When the internal heat exchange structure of the air-cooled heat dissipation channel 1 is constructed using straight fins 201, the straight fins 201 are arranged in a straight line, which has low processing cost, is easy to mass-produce, has low flow resistance, smooth airflow path, and low pressure drop. It is suitable for low flow velocity or natural convection scenarios. The heat exchange efficiency is moderate, but the turbulence effect is weak, the thermal boundary layer is thick, the uniformity is high, and the heat distribution is uniform, making it suitable for scenarios with high requirements for temperature consistency.

[0040] When the internal heat exchange structure of the air-cooled heat dissipation channel 1 is constructed using wavy fins 202, the wavy structure of the wavy fins 202 disrupts the boundary layer, effectively improving the heat transfer coefficient and heat dissipation efficiency. It has stronger heat dissipation capacity under the same volume, making it suitable for high heat flux density scenarios. However, it has high flow resistance and airflow disturbances that lead to higher pressure drop, requiring greater driving power. Its compact design achieves higher heat dissipation performance in a limited space, such as in servers or high-power electronic devices. In forced convection environments, it can be paired with high-speed fans or pumps to offset the disadvantage of high resistance and give full play to the advantages of efficient heat dissipation.

[0041] Features of cylindrical ribs 301: symmetrical structure, uniform boundary layer separation when airflow passes around it, generating periodic vortices, enhancing turbulent mixing, moderate heat transfer coefficient, low pressure drop, moderate flow resistance, strong mechanical strength, circular cross-section has strong resistance to pressure and deformation, suitable for high vibration environments, simple processing, but high cost when densely arranged.

[0042] Features of the semi-circular rib 302: Asymmetrical structure, airflow is accelerated on the convex surface and vortex is formed on the concave surface, the local heat transfer coefficient is improved, the drag pressure drop is slightly higher than that of the cylindrical shape, the installation direction affects the performance, and it can be arranged to fit the surface in space, making it suitable for compact designs in confined spaces.

[0043] The semi-circular triangular ribbed column 303 has the following characteristics: the sharp leading edge causes strong boundary layer separation, forming a high turbulence wake region, the highest heat transfer coefficient, significantly increased drag pressure drop, requiring greater driving power, large heat transfer area per unit volume, suitable for high heat flux density scenarios, the sharp angle is prone to stress concentration, and the stamping or etching process has high requirements.

[0044] Second implementation method:

[0045] Compared to the first implementation, the main difference is the specific form of the wavy rib 202 in the rib module. The specific new structure is as follows, while the rest of the structure is the same as the first implementation.

[0046] Figures 9 to 11 As shown, the top and bottom of the wavy rib 202 are slidably connected to the inner wall of the air-cooled heat dissipation channel 1, and the wavy rib 202 is made of titanium alloy. Temperature control targets 4 are fixedly distributed in a matrix between the air-cooled heat dissipation channel 1 and the heat exchange recess 101. A connecting rib 401 is fixedly connected between the top of the temperature control target 4 and the inner recess of the wavy rib 202. The connecting rib 401 is made of shape memory alloy. An active groove 402 communicating with the heat exchange recess 101 is opened in the middle of the temperature control target 4. The temperature control target 4 is made of aerogel material. The temperature control target 4 made of aerogel material has low thermal conductivity, so as to achieve the heat insulation effect of the temperature control target 4.

[0047] When the rib module is combined with the corrugated ribs 202, the corrugated ribs 202 made of titanium alloy have excellent elastic deformation ability. The temperature of the heat exchange concave area 101 is monitored locally by the temperature control target 4. The temperature of this area triggers the thermal deformation ability of the connecting rib 401. After the thermal deformation of the connecting rib 401, it pushes the concave part of the corrugated rib 202 to achieve further bending, thereby enhancing the irregularity of the corrugated rib 202 in this area, that is, effectively enhancing the turbulence disturbance ability of the fluid and locally improving the heat exchange capacity of this area. Subsequently, after the temperature drops, the shape of the connecting rib 401 returns to normal after the temperature drops, and the corrugated rib 202 also automatically returns to normal shape, thereby effectively avoiding long-term turbulence in this area and affecting the fluid flow capacity of other areas.

[0048] Figures 10 to 11As shown, the top and bottom of the connecting rib 401 are both curved, and a heat insulation sleeve 403 covers the top of the connecting rib 401 and the top of the temperature control body 4. The movable groove 402 is sleeved with the bottom curved end of the connecting rib 401. The connecting rib 401, made of shape memory alloy material, bends at the curved position, thereby using the change in the bending amplitude of the connecting rib 401 to drive the deformation of the wave-shaped rib 202, changing the local bending amplitude of the wave-shaped rib 202, thereby effectively enhancing the fluid disturbance capability of the area and effectively improving the heat exchange capability of the area. The heat insulation sleeve 403 effectively improves the heat insulation capability of the connecting rib 401, thereby extending the deformation state time of the connecting rib 401, that is... To extend the time for improving the heat exchange capacity of this area, a sealing plate 404 is fixedly connected to the lower opening of the movable groove 402. The bottom arc-shaped end of the connecting rib 401 contacts and corresponds to the sealing plate 404. The sealing plate 404 is made of aluminum alloy. The sealing plate 404 is used to seal the lower part of the movable groove 402, effectively preventing the fluid inside the air-cooled heat dissipation channel 1 from leaking into the heat exchange recess 101. Furthermore, the heat conduction through the contact between the connecting rib 401 and the sealing plate 404 facilitates the heat deformation of the connecting rib 401. After the connecting rib 401 deforms, the contact between the connecting rib 401 and the sealing plate 404 is broken, thereby effectively reducing the heat dissipation of the connecting rib 401 and extending the deformation time of the connecting rib 401.

[0049] When the connecting rib 401 bends and deforms due to temperature changes, the arc bending amplitude at the top of the connecting rib 401 decreases, thereby applying a lateral thrust to the corrugated rib 202. This pushes the concave part of the corrugated rib 202 to bend further, achieving further irregular adjustment of the fluid flow path, effectively enhancing the fluid's turbulence disturbance capability, and locally improving the heat transfer capacity of this area. The arc bending amplitude at the bottom of the connecting rib 401 increases, achieving disconnection between the connecting rib 401 and the sealing plate 404, cutting off the heat transfer between the connecting rib 401 and the sealing plate 404. At the same time, the heat insulation sleeve 403 wraps and insulates the exposed connecting rib 401, so that when efficient turbulence heat dissipation is carried out in this area, the heat dissipation capacity of the connecting rib 401 is relatively lower, thereby effectively increasing the maintenance time of the thermal deformation state of the connecting rib 401, effectively avoiding the corrugated rib 202 bending deformation time being too short, and effectively avoiding affecting the local turbulence enhancement capability of the corrugated rib 202.

[0050] Figures 12 to 13As shown, the lower edge of the wavy rib 202 has a groove 5, and a thermally conductive silicone strip 501 is fixedly embedded inside the groove 5. The thermally conductive silicone strip 501 is slidably connected to the inner wall of the air-cooled heat dissipation channel 1, effectively improving the heat exchange capacity between the wavy rib 202 and the inner wall of the air-cooled heat dissipation channel 1. A foot piece 502 is fixedly connected at equal intervals in the middle of the thermally conductive silicone strip 501. Both ends of the foot piece 502 are fixedly connected to the inner wall of the air-cooled heat dissipation channel 1. The thermally conductive silicone strip 501 is buffered and fixed to the air-cooled heat dissipation channel 1 through the foot piece 502, retaining a certain range of motion for the thermally conductive silicone strip 501. Both ends of the foot piece 502 are provided with arched buffer portions 503, and the foot piece 502 is made of elastic material. Made of plastic, the foot pad 502 bends through the arched buffer part 503 to adapt to the movement of the thermally conductive silicone strip 501. The bottom of the arched buffer part 503 near the thermally conductive silicone strip 501 has a locking hole 504. A locking screw 505 is inserted into the locking hole 504. The bottom of the locking screw 505 is threaded to the inner wall of the air-cooled heat dissipation channel 1, and the top of the locking screw 505 contacts the side of the wave-shaped rib 202. The locking screw 505 passes through the locking hole 504 and is threaded to the air-cooled heat dissipation channel 1, thereby fixing the displacement capability of the wave-shaped rib 202 in this area, thus providing a force support point for adjusting the bending amplitude of the wave-shaped rib 202.

[0051] When installing the corrugated fin 202, a thermally conductive silicone strip 501 is fixedly embedded in the groove 5 at the lower edge of the corrugated fin 202. The corrugated fin 202 contacts the air-cooled heat dissipation channel 1 through the thermally conductive silicone strip 501, effectively improving the heat exchange capacity between the corrugated fin 202 and the air-cooled heat dissipation channel 1, without affecting the bending amplitude adjustment capability of the corrugated fin 202, facilitating heat dissipation through the corrugated fin 202. The thermally conductive silicone strip 501 is fixed to the air-cooled heat dissipation channel 1 by the pads 502, and the arched buffer portions 503 at both ends serve as pads. The left and right swing amplitude of the foot piece 502 reaches the limit of the movable range of the thermal conductive silicone strip 501, and the thermal conductive silicone strip 501 automatically recovers through the elasticity of the arched buffer part 503. When installing the foot piece 502, the position of the deformation fulcrum of the wavy rib 202 is determined according to the distribution position of the temperature control target body 4. The locking screw 505 is threaded through the locking hole 504 to connect the air cooling heat dissipation channel 1, thereby fixing the displacement capacity of the wavy rib 202 in this area, thereby providing a force fulcrum for adjusting the bending amplitude of the wavy rib 202.

[0052] In light of current practical needs, the above-described embodiments adopted in this application are not limited to this scope of protection. Various changes made within the knowledge of those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
