Abstract
Description
Technical Field
[0001] This invention relates to the field of radiator technology, specifically to a high-efficiency and energy-saving radiator. Background Technology
[0002] Finned tube radiators are core heat exchange equipment widely used in industrial heating, HVAC, chemical heat exchange, and power machinery. Their basic working principle is as follows: high-temperature medium flows through the inside of the finned tube, and heat is transferred to the fins through the tube wall. Then, forced convection air driven by a fan carries away the heat from the surface of the fins, thereby achieving cooling of the medium. Due to their compact structure, high heat transfer efficiency, and strong adaptability, finned tube radiators play an important role in generator cooling, air coolers, waste heat recovery systems, and various industrial heat dissipation applications.
[0003] Currently, the typical structure of a finned tube radiator includes a heat dissipation shell, finned tube bundles, and a fan system. The heat dissipation shell is usually a rectangular or box-shaped structure with multiple sets of finned tubes arranged in parallel inside. An air inlet is provided on one side of the shell, and an air outlet is provided on the other side. The fan is installed on the air outlet side to guide the airflow by exhaust (or installed on the air inlet side to blow air). During operation, the fan runs to create forced convection inside the shell. External cold air enters the shell, and after horizontally scouring the finned tube bundles, the hot air carrying heat is discharged from the air outlet. The high-temperature medium inside the finned tubes is cooled down through forced convection heat exchange with the air.
[0004] However, the above structure has the following technical defects in actual operation. When air flows inside the radiator, the airflow mainly passes through the central area of the radiator quickly along the path with less resistance. The airflow path is short and the flow velocity is high. Some air does not make sufficient contact with the surface of the finned tubes before quickly passing through the fin gaps and being discharged from the air outlet, resulting in a waste of effective heat exchange area. At the same time, the finned tube bundles near the four corners and edges of the radiator cannot obtain sufficient airflow, forming heat dissipation dead zones. Due to the lack of effective airflow scouring, the convective heat transfer coefficient between the finned tubes and the air in the above areas is significantly lower than the design value, resulting in uneven temperature distribution of the radiator as a whole. Some pipes are in a high-temperature operating state for a long time, affecting the heat dissipation effect. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides a high-efficiency and energy-saving radiator, aiming to solve the problem of low heat exchange efficiency caused by airflow short-circuiting in existing radiators.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency energy-saving radiator, comprising a radiator shell and multiple sets of heat dissipation pipes passing through the radiator shell. The portion of each heat dissipation pipe located within the radiator shell is fixedly fitted with multiple circular heat dissipation fins at equal intervals. The radiator shell contains multiple vertical partitions and multiple vertical baffles. Each vertical baffle is positioned between two adjacent vertical partitions. The multiple vertical partitions and multiple vertical baffles are respectively positioned between two rows of adjacent heat dissipation pipes. When the upper ends of the multiple vertical partitions abut against the upper wall of the radiator shell, the lower ends of the multiple vertical baffles contact the radiator shell. When the lower walls abut against each other, and the lower ends of the multiple vertical baffles abut against the lower wall of the radiator housing, the upper ends of the multiple vertical baffles abut against the upper wall of the radiator housing. A power mechanism for controlling the staggered lifting and lowering of the multiple vertical baffles and the multiple vertical baffles is installed at the upper end of the radiator housing. A ring is rotatably sleeved on the heat dissipation pipe. A connecting piece for cleaning the gaps of the circular heat dissipation fins is installed on the ring. A pushing piece for controlling the rotation of the ring is provided between the ring and the vertical baffles. When the vertical baffles are raised and lowered to change the airflow direction, they are also used to control the rotation of the ring to clean the gaps of the circular heat dissipation fins. An agitator is installed on the connecting piece.
[0007] Preferably, it further includes a mounting housing fixedly connected to one side of the radiator housing, a fan fixedly installed inside the mounting housing, a first pipe and a second pipe provided on one side of the radiator housing, the water inlet ends of multiple sets of heat dissipation pipes fixedly connected to the second pipe, the water outlet ends of multiple sets of heat dissipation pipes fixedly connected to the first pipe, and connection ports fixedly connected to both the second pipe and the first pipe, a first filter screen plate installed on one side of the radiator housing, and a second filter screen plate installed on the outside of the mounting housing.
[0008] Preferably, the power mechanism includes a heat insulation shell fixedly installed on the upper end of the radiator shell, a dual-axis motor fixedly installed on the upper wall of the heat insulation shell, and rotating shafts fixedly installed on both output ends of the dual-axis motor. The radiator shell is provided with a first lifting member for controlling the lifting and lowering of the vertical baffle and a second lifting member for controlling the lifting and lowering of the vertical baffle. When the two rotating shafts rotate, they are used to control the first lifting member and the second lifting member to move up and down in a staggered manner, respectively.
[0009] Preferably, the first lifting member includes a first connecting plate fixedly connected to one of the rotating shafts, a sliding rod rotatably mounted on one side of the first connecting plate, a connecting rod fixedly mounted on the upper end of each of the plurality of vertical baffles, the upper ends of the plurality of connecting rods being located inside the heat insulation shell, a fixing plate fixedly connected between the upper ends of the plurality of connecting rods, a horizontal sliding groove being provided on one side of the fixing plate, and the sliding rod slidingly contacting the horizontal sliding groove.
[0010] Preferably, the second lifting member is fixedly connected to a second connecting plate with another rotating shaft. A sliding column is rotatably installed on one side of the second connecting plate. A connecting column is fixedly installed on the upper end of each of the multiple vertical partitions. The upper ends of the multiple connecting columns are located inside the heat insulation shell. An mounting plate is fixedly connected between the upper ends of the multiple connecting columns. A horizontal connecting groove is opened on one side of the mounting plate. The sliding column slides in contact with the horizontal connecting groove.
[0011] Preferably, the connector includes a plurality of toothed plates disposed on one side of the ring. Each toothed plate includes a rotating plate fixedly connected to the ring. The rotating plate is fixedly mounted with a plurality of toothed blocks at equal intervals on one side of the circular heat dissipation fins. Each toothed block is located between two adjacent circular heat dissipation fins.
[0012] Preferably, the pushing component includes multiple sets of push rods fixedly installed on both sides of the vertical partition, and multiple fixed posts are installed at equal intervals on one side of the ring, with each fixed post located between two adjacent push rods. The lifting and lowering of the push rods is used to control the rotation of the ring.
[0013] Preferably, the agitator includes agitator blades fixedly installed on one side of the rotating plate.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. By arranging multiple vertical baffles and vertical partitions inside the radiator housing, with each vertical baffle positioned between two adjacent vertical baffles, and simultaneously placing these baffles and partitions between two adjacent rows of heat dissipation pipes, this invention constructs a guiding structure that directs airflow in a meandering manner. Specifically, when the upper ends of the vertical baffles abut against the upper wall of the radiator housing, the lower ends of the vertical baffles abut against the lower wall of the radiator housing; conversely, when the lower ends of the vertical baffles abut against the lower wall of the radiator housing, the upper ends of the vertical baffles abut against the upper wall of the radiator housing. Through this staggered arrangement of alternating abutments, the internal airflow is forced to meander along an S-shaped path. This configuration significantly improves airflow efficiency. The flow path and residence time of the gas within the radiator housing are extended, allowing the airflow to flow sequentially over the surfaces of each heat pipe and circular heat dissipation fin, effectively covering the original airflow dead zones within the housing. This ensures that each heat pipe and circular heat dissipation fin can fully contact the airflow. When the power mechanism is working, it controls the vertical baffles and vertical baffles to move in a staggered up-and-down motion, causing the internal airflow guidance path to continuously and dynamically change. The corner areas that were originally difficult to reach are periodically and effectively flushed by airflow, thereby eliminating flow dead zones, effectively extending the residence time of the gas within the radiator housing, eliminating flow dead zones caused by airflow short circuits, and ensuring that each heat pipe and circular heat dissipation fin can fully contact the airflow.
[0016] 2. By rotating a ring on the heat dissipation pipe and fixing a toothed plate on one side of the ring for cleaning the gaps between the circular heat dissipation fins, this invention constructs an online dust removal structure that can actively clean the gaps between the circular heat dissipation fins. When the ring is rotated, it drives the toothed plate to move synchronously, causing the toothed blocks on the toothed plate to move back and forth in the gap between the two circular heat dissipation fins. This setting can effectively avoid the reduction of the effective contact area between the circular heat dissipation fins and the airflow due to dust accumulation, ensuring good heat exchange conditions between the airflow and the circular heat dissipation fins, and significantly improving the long-term operational stability and heat exchange efficiency of the radiator in dusty environments.
[0017] 3. By installing multiple sets of push rods on both sides of the vertical partition and installing multiple fixed columns at equal intervals on one side of the ring corresponding to the positions of the push rods, this invention constructs a linkage transmission mechanism that converts the lifting motion of the vertical partition into the rotational motion of the ring. When the motor controls the lifting of the vertical partition, the vertical partition drives multiple sets of push rods to move synchronously. During the movement, the push rods contact the fixed columns and push them to move. The fixed columns then drive the ring to rotate around the axis of the heat dissipation pipe, thereby driving the toothed plate to perform the dust removal action. With this setting, the power source of the dust removal mechanism and the power source of the airflow guiding mechanism inside the radiator are combined into one, eliminating the need to add a separate motor and control system for the dust removal function.
[0018] 4. By installing stirring blades on one side of the rotating plate, the ring drives the rotating plate and stirring blades to move synchronously during the rotation of the ring, thereby actively stirring the airflow near the stirring blades and generating local turbulence in the area. This setting can effectively disrupt the laminar boundary layer on the surface of the heat dissipation tube and the circular heat dissipation fins, enhance the degree of turbulence disturbance of the local airflow, and significantly improve the convective heat transfer coefficient. Compared with the traditional heat exchange method that relies on the mainstream air scouring, the local turbulence generated by the stirring blades can continuously renew the thermal boundary layer on the surface of the circular heat dissipation fins, maintain a large temperature gradient between the high-temperature circular heat dissipation fins and the low-temperature air, thereby greatly improving the heat exchange efficiency per unit area and achieving higher heat dissipation effect with lower energy consumption.

[0029] The embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings and examples. The detailed description of the embodiments and the accompanying drawings are used to illustrate the principles of this disclosure by way of example, but should not be used to limit the scope of this disclosure. This disclosure can be implemented in many different forms and is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
[0030] Please see Figures 1-9A high-efficiency energy-saving radiator includes a radiator shell 1 and multiple sets of heat dissipation pipes 3 passing through the radiator shell 1. The portion of the heat dissipation pipes 3 located inside the radiator shell 1 is fitted with multiple circular heat dissipation fins 7 at equal intervals (the circular heat dissipation fins 7 are made of aluminum alloy and are integral with the heat dissipation pipes 3, unlike the welding method of general fins and radiator pipes, increasing reliability and reducing thermal resistance). It also includes a mounting shell 26 fixedly connected to one side of the radiator shell 1. A fan 2 is fixedly installed inside the mounting shell 26 (the fan 2 can exhaust or blow air, depending on the actual situation). A first pipe 30 and a second pipe 28 are provided on one side of the radiator shell 1. The water inlet ends of the multiple sets of heat dissipation pipes 3 are all fixedly connected to the second pipe 28, and the water outlet ends of the multiple sets of heat dissipation pipes 3 are all fixedly connected to the first pipe 30 (water inlet...). (The end and outlet can also be selected according to the actual situation). Connection ports 29 are fixedly connected to the second pipe 28 and the first pipe 30. A first filter screen plate 25 is installed on one side of the radiator shell 1, and a second filter screen plate 27 is installed on the outside of the mounting shell 26. Hot water passes through the heat dissipation pipe 3 inside the radiator shell 1. At the same time, the fan 2 works (exhaust type: the air inside the radiator shell 1 is drawn outward, so that a negative pressure is formed inside the radiator shell 1. The external cold air is forced in from the air inlet at the other end of the radiator shell 1, flows through the heat dissipation area and is discharged from the fan 2 end; blowing type: the external cold air is blown directly into the radiator shell 1 to form a positive pressure. The cold air is forced to flow through the heat dissipation area and is discharged from the air outlet at the other end). The hot water in the heat dissipation pipe 3 is cooled by the heat dissipation pipe 3 and the circular heat dissipation fins 7.
[0031] To effectively prolong the residence time of gas within the radiator housing 1, eliminate flow dead zones caused by airflow short-circuiting, and ensure that each heat dissipation pipe 3 and circular heat dissipation fin 7 can fully contact the airflow, multiple vertical baffles 5 and multiple vertical baffles 6 are arranged inside the radiator housing 1. Each vertical baffle 6 is positioned between two adjacent vertical baffles 5, and the multiple vertical baffles 5 and multiple vertical baffles 6 are respectively positioned between two rows of adjacent heat dissipation pipes 3. This invention constructs a guiding structure that can guide the airflow to meander. When the upper ends of the multiple vertical baffles 5 abut against the upper wall of the radiator housing 1, the lower ends of the multiple vertical baffles 6 abut against the lower wall of the radiator housing 1; when the lower ends of the multiple vertical baffles 5 abut against the lower wall of the radiator housing 1, the upper ends of the multiple vertical baffles 6 abut against the upper wall of the radiator housing 1. Through the aforementioned staggered arrangement of alternating and counteracting elements, the internal airflow is forced to meander along an S-shaped path. This arrangement significantly extends the flow path and residence time of the gas within the radiator housing 1, allowing the airflow to flow sequentially over the surfaces of each heat pipe 3 and the circular heat dissipation fins 7, and effectively covering the original airflow dead zones within the radiator housing 1. This ensures that each heat pipe 3 and the circular heat dissipation fins 7 can fully contact the airflow. The upper end of the radiator housing 1 is equipped with a power mechanism that controls the staggered lifting and lowering of multiple vertical baffles 5 and multiple vertical baffles 6. When the power mechanism is working, it controls the staggered lifting and lowering of the vertical baffles 5 and vertical baffles 6, causing the internal airflow guidance path to continuously and dynamically change. The corner areas that were originally difficult to reach can be periodically and effectively flushed by airflow, thereby eliminating flow dead zones.
[0032] A circular ring 8 is rotatably mounted on the heat sink 3. A connector for cleaning the gaps between the circular heat sink fins 7 is installed on the circular ring 8. The connector includes multiple toothed plates 9 disposed on one side of the circular ring 8. Each toothed plate 9 includes a rotating plate 902 fixedly connected to the circular ring 8. Multiple toothed blocks 901 are fixedly installed at equal intervals on one side of the circular heat sink fins 7 on the rotating plate 902. Each toothed block 901 is located between two adjacent circular heat sink fins 7. When the circular ring 8 is rotated, the circular ring 8 drives the toothed plates 9 to move synchronously, causing the toothed blocks 901 on the toothed plates 9 to reciprocate within the gaps between the two circular heat sink fins 7. (It should be noted that the primary function of the toothed blocks 901 is not to clean the gaps between the circular heat sink fins 7.) The dust between the two circular heat dissipation fins 7 is thoroughly cleaned to keep them completely clean at all times. This is to prevent the gaps between the circular heat dissipation fins 7 from being filled with dust. As the operating time increases, if the gaps between the circular heat dissipation fins 7 are gradually blocked by dust, the airflow cross-sectional area will decrease, and the effective contact area between the circular heat dissipation fins 7 and the air will be significantly reduced. This setting can effectively avoid the reduction of the effective contact area between the circular heat dissipation fins 7 and the airflow due to dust accumulation, ensuring good heat exchange conditions between the airflow and the circular heat dissipation fins 7, and significantly improving the long-term operating stability and heat exchange efficiency of the radiator in dusty environments.
[0033] A pusher is provided between the circular ring 8 and the vertical partition 5 to control the rotation of the circular ring 8. When the vertical partition 5 is raised or lowered to change the airflow direction, it is also used to control the rotation of the circular ring 8 to clean the gaps in the circular heat dissipation fins 7. An agitator is installed on the connector. The pusher includes multiple sets of push rods 21 fixedly installed on both sides of the vertical partition 5. Multiple fixed posts 11 are installed at equal intervals on one side of the circular ring 8. Each fixed post 11 is located between two adjacent push rods 21. The raising and lowering of the push rods 21 is used to control the rotation of the circular ring 8, thus constructing a mechanism for raising the vertical partition 5. The linkage transmission mechanism converts the downward motion into the rotational motion of the ring 8. When the power mechanism controls the vertical partition 5 to rise and fall, the vertical partition 5 drives multiple sets of push rods 21 to move synchronously. During the movement, the push rods 21 contact the fixed column 11 and push it to move. The fixed column 11 then drives the ring 8 to rotate around the axis of the heat dissipation pipe 3, thereby driving the toothed plate 9 to perform the dust cleaning action. In this way, the power source of the dust cleaning mechanism and the power source of the airflow guiding mechanism inside the radiator are combined into one, without the need to add an independent motor and control system for the dust cleaning function.
[0034] As a further technical solution of the present invention, the power mechanism includes a heat insulation shell 4 fixedly installed on the upper end of the radiator shell 1. A dual-axis motor 14 is fixedly installed on the upper wall of the heat insulation shell 4. Rotating shafts 22 are fixedly installed on both output ends of the dual-axis motor 14. A first lifting member for controlling the lifting and lowering of the vertical baffle 6 and a second lifting member for controlling the lifting and lowering of the vertical baffle 5 are provided inside the radiator shell 1. When the two rotating shafts 22 rotate, they are used to control the staggered lifting and lowering of the first and second lifting members, respectively. The first lifting member includes a first connecting plate 20 fixedly connected to one of the rotating shafts 22. A sliding rod 23 is rotatably mounted on one side of the connecting plate 20. Connecting rods 13 are fixedly mounted on the upper ends of multiple vertical baffles 6. The upper ends of the multiple connecting rods 13 are all located inside the heat insulation shell 4. A fixing plate 16 is fixedly connected between the upper ends of the multiple connecting rods 13. A horizontal sliding groove 24 is provided on one side of the fixing plate 16. The sliding rod 23 slides in contact with the horizontal sliding groove 24. The second lifting member is fixedly connected to a second connecting plate 18 of another rotating shaft 22 (when the end of the second connecting plate 18 away from the rotating shaft 22 is above, the end of the first connecting plate 20 away from the rotating shaft 22 is below, and the end of the second connecting plate 18 away from the rotating shaft 22 is below). When one end of 22 is at the bottom, the end of the first connecting plate 20 away from the rotating shaft 22 is at the top. A sliding column 17 is rotatably installed on one side of the second connecting plate 18. A connecting column 12 is fixedly installed on the upper end of each of the multiple vertical partitions 5. The upper ends of the multiple connecting columns 12 are all located inside the heat insulation shell 4. A mounting plate 15 is fixedly connected between the upper ends of the multiple connecting columns 12. A horizontal connecting groove 19 is opened on one side of the mounting plate 15. The sliding column 17 slides in contact with the horizontal connecting groove 19. The dual-axis motor 14 controls the rotation of the two rotating shafts 22. One of the rotating shafts 22 drives the first connecting plate 20 to rotate. The connecting plate 20 drives the sliding rod 23 to move. The sliding rod 23 slides in the horizontal sliding groove 24, pushing the fixed plate 16 to move upward. The fixed plate 16 drives the vertical baffle 6 to move upward through multiple connecting rods 13, so that its upper end abuts against the upper wall of the radiator housing 1. At the same time, another rotating shaft 22 drives the second connecting plate 18 to rotate. The second connecting plate 18 drives the sliding column 17 to move. The sliding column 17 slides in the horizontal connecting groove 19, pushing the mounting plate 15 to move downward. The mounting plate 15 drives the vertical partition 5 to move downward through multiple connecting columns 12, so that its lower end abuts against the lower wall of the radiator housing 1, thereby changing the airflow path.
[0035] As a further technical solution of the present invention, the agitator includes an agitator blade 10 fixedly installed on one side of the rotating plate 902. During the rotation of the ring 8, the agitator blade 10 is controlled to move synchronously, thereby actively agitating the airflow near the agitator blade 10, causing local turbulence in the area, which can effectively destroy the laminar boundary layer on the surface of the heat dissipation pipe 3 and the circular heat dissipation fin 7, enhance the degree of turbulence disturbance of the local airflow, and significantly improve the convective heat transfer coefficient.
[0036] During work:
[0037] I. Initial State and Medium Introduction Stage
[0038] The operator introduces a high-temperature medium, such as water or oil, into the second pipe 28 through the connection port 29. After being distributed through the second pipe 28, the medium enters the inlet end of multiple sets of heat dissipation pipes 3. After flowing through the heat dissipation pipes 3, it is collected from the outlet end to the first pipe 30 and output through another connection port 29. At the same time, the fan 2 is started, and the exhaust or blowing mode is selected according to the working conditions to form forced convection inside the radiator shell 1.
[0039] Working effect: As the high-temperature medium flows through the heat dissipation pipe 3, the heat is transferred to the circular heat dissipation fins 7 through the pipe wall, which prepares for the subsequent forced convection heat exchange with the air. The start-up of the fan 2 provides forced convection power for the radiator.
[0040] II. Airflow Guidance and Dynamic Distribution Stage
[0041] In the initial state, the upper ends of multiple vertical baffles 5 abut against the upper wall of the radiator housing 1, and the lower ends of multiple vertical baffles 6 abut against the lower wall of the radiator housing 1, forming the first airflow guiding state. External cold air enters the radiator housing 1 under the action of the fan 2 and is forced to travel along an S-shaped path, flowing through the surface of each heat dissipation pipe 3 and the circular heat dissipation fin 7 in sequence.
[0042] Working effect: Through the alternating and offset staggered arrangement, the internal airflow is forced to travel along an S-shaped path, which significantly prolongs the flow path and residence time of the gas in the radiator housing 1. This allows the airflow to flow through the surface of each heat pipe 3 and the circular heat dissipation fin 7 in sequence, and effectively covers the original airflow dead zone area in the radiator housing 1, ensuring that each heat pipe 3 and the circular heat dissipation fin 7 can fully contact the airflow.
[0043] The dual-axis motor 14 operates, controlling the two rotating shafts 22 to rotate synchronously. One rotating shaft 22 drives the fixed plate 16 to move upward through the first connecting plate 20 and the slide rod 23. The fixed plate 16 drives the vertical baffle 6 to move upward through the connecting rod 13, so that its upper end abuts against the upper wall of the radiator housing 1. The other rotating shaft 22 drives the mounting plate 15 to move downward through the second connecting plate 18 and the slide column 17. The mounting plate 15 drives the vertical partition 5 to move downward through the connecting column 12, so that its lower end abuts against the lower wall of the radiator housing 1, thus completing the switching of the airflow guidance path. The dual-axis motor 14 continues to operate, causing the vertical partition 5 and the vertical baffle 6 to periodically move up and down in a staggered manner.
[0044] Working effect: When the power mechanism is working, it controls the vertical baffle 5 and the vertical baffle 6 to move up and down in a staggered manner, so that the internal airflow guide path changes continuously and dynamically. The corner areas that were originally difficult to reach can be periodically flushed by effective airflow, thereby eliminating the flow dead zone and realizing the adaptive adjustment of airflow distribution.
[0045] III. Online Dust Removal and Local Turbulence Enhancement Stage
[0046] During the lifting and lowering of the vertical partition 5, multiple sets of push rods 21 fixedly installed on both sides of it move synchronously. During the movement, the push rods 21 contact the fixed column 11 on one side of the ring 8 and push it to move. The fixed column 11 drives the ring 8 to rotate around the axis of the heat dissipation pipe 3. The ring 8 drives the toothed plate 9 to rotate synchronously, so that the toothed block 901 on the toothed plate 9 moves back and forth in the gap between the two circular heat dissipation fins 7.
[0047] Working effect: The power source of the dust cleaning mechanism and the power source of the airflow guiding mechanism inside the radiator are combined into one, eliminating the need to add a separate motor and control system for the dust cleaning function. The reciprocating movement of the tooth block 901 in the gap of the circular heat dissipation fin 7 can effectively prevent the gap from being filled with dust, maintain the airflow cross-sectional area, and ensure good heat exchange conditions between the airflow and the circular heat dissipation fin 7.
[0048] During the rotation of the ring 8, the stirring blades 10 fixedly installed on one side of the rotating plate 902 move synchronously, actively stirring the airflow near the stirring blades 10, causing local turbulence in the area;
[0049] Working effect: The local turbulence generated by the stirring blades 10 can effectively disrupt the laminar boundary layer on the surface of the heat dissipation tube 3 and the circular heat dissipation fins 7, enhance the degree of turbulence disturbance of the local airflow, and significantly improve the convective heat transfer coefficient. Compared with the traditional heat exchange method that relies on the mainstream air scouring, the local turbulence can continuously renew the thermal boundary layer on the surface of the circular heat dissipation fins 7, so as to maintain a large temperature gradient between the high temperature circular heat dissipation fins 7 and the low temperature air, thereby greatly improving the heat exchange efficiency per unit area.
