[0037] Specifically, it refers to a circulating heat exchange processing device of a vehicle refrigeration system, comprising a frame 1, a plurality of spaced parallel arranged heat dissipation fins 2 are arranged in the frame 1, a continuous curved arranged heat exchange pipe 3 is embedded on the frame 1, and the plurality of heat dissipation fins 2 are all sleeved on the outer surface of the heat exchange pipe 3 located in the frame 1. The heat dissipation fins 2 and the section of the heat exchange pipe 3 located in the frame 1 are all made of high thermal conductivity material. The heat exchange pipe 3 is provided with a flange joint 4 at both ends, which is connected with the refrigeration pipeline of the vehicle. During the driving of the vehicle, the pump body delivers the cooling liquid into the heat exchange pipe 3. The cooling liquid passes through the continuously curved heat exchange pipe 3, so that the heat in the cooling liquid is conducted to the heat dissipation fins 2 through the heat exchange pipe 3, and at the same time, the external cold air is blown to the heat dissipation fins 2 through the vehicle grille. The airflow flowing between the adjacent two heat dissipation fins 2 can take away the heat, so as to achieve the purpose of heat exchange of the cooling liquid in the heat exchange pipe 3.

[0038] The heat dissipation fin 2 comprises a fixed fin 21 mounted on the outer surface of the heat exchange pipe 3 located in the frame 1, the rear side of the fixed fin 21 is provided with a Z-shaped swinging fin 22, the upper and lower side surfaces of the rear side of the fixed fin 21 are both provided with a groove 23, the upper and lower protruding parts of the swinging fin 22 respectively extend into the two grooves 23, the swinging shaft 24 is arranged between the groove 23 and the protruding part of the swinging fin 22, and the swinging shaft 24 is rotationally connected with the inner wall of the groove 23, so that the swinging fin 22 swings around the swinging shaft 24 as the rotation point in use, so that the vehicle is aerodynamically self-leveling when running at high speed, the high-speed airflow is adsorbed and attached to the surface of the swinging fin 22 to form an aviation laminar flow shape, which can reduce the wind resistance to a certain extent, and when the vehicle runs at low speed, the swinging fin 22 destroys the laminar boundary layer at the fixed fin 21 to generate tail vortex mixing, thereby further improving the heat dissipation efficiency of the vehicle when running at low speed.

[0039] In use, the front surface of the fixed fin 21 is the windward surface, so as to keep the structure main body stable and avoid overall vibration, and the swinging fin 22 is arranged on the leeward surface, the swinging amplitude on the leeward surface is constrained by physical limiting, and the risk of air duct blockage caused by uncontrolled swinging is eliminated.

[0040] The front surface of the fixed fin 21 is provided with two air inlet grooves 25 arranged in parallel upward and downward, the air inlet grooves 25 are trumpet-shaped, the rear side of the air inlet grooves 25 is provided with a straight groove 26, the bottom wall of the upper straight groove 26 is rotationally connected with a connecting shaft 216, the outer surface of the connecting shaft 216 is sleeved with a first gear 27, the outer surface of the first gear 27 is engaged with a first rack 28, the rear side of the straight groove 26 is provided with a sleeving rod 29, a sliding groove (not shown in the figure) is formed in the surface of the first rack 28 close to the sleeving rod 29, the first rack 28 is slidably sleeved on the outer surface of the sleeving rod 29 through the sliding groove, and the first rack 28 is movably sleeved on the outer surface of the sleeving rod 29 between the straight groove 26 and the inner wall.

[0041] The upper side of the fixed fin 21 is provided with a speed reduction cavity 217, the upper end of the connecting shaft 216 rotationally penetrates into the speed reduction cavity 217, and the lower end of the upper swinging shaft 24 also rotationally penetrates into the speed reduction cavity 217, and the connecting shaft 216 and the swinging shaft 24 are provided with a speed reduction assembly.

[0042] When the vehicle stops running, the first tension spring 210 pulls the first rack 28 to be close to the rear side of the straight groove 26, so that the swinging shaft 24 swings the swinging fin 22 to an initial state of an inclined state, and the swinging fin 22 is attached to the surface of the fixed fin 21. Figure 4So that the air duct between the two fixed fins 21 is inclined, when the vehicle is cold started in low temperature environment, the swing fin 22 maintains the inclined state because the low speed airflow cannot drive the swing fin 22 to swing when cold started, so as to reduce the heat dissipation efficiency of the fixed fin 21, thereby improving the warm-up efficiency of the vehicle when cold started in low temperature environment, and further reducing the fuel consumption of the vehicle when cold started.

[0043] The right inner wall of the air inlet groove 25 is rotationally connected with a mounting rotating shaft 212, the left end of the mounting rotating shaft 212 is provided with a fan blade 213, the left side surface of the fan blade 213 is provided with a sleeving shaft 214, the sleeving shaft 214 is arranged at the eccentric position of the circular surface of the fan blade 213, the front side surface of the first rack 28 is provided with a pulling rod 211, the front end of the pulling rod 211 extends into the air inlet groove 25, the outer surface of the sleeving shaft 214 is rotationally sleeved with a rotating push plate 215, the other side of the rotating push plate 215 is hingedly connected with the front end of the pulling rod 211.

[0044] When the vehicle is running, the airflow blows to the windward surface of the fixed fin 21, part of the airflow enters the air inlet groove 25, the airflow forms a thrust on the fan blade 213, and the mounting rotating shaft 212 rotates synchronously with the fan blade 213, at this time, the sleeving shaft 214 rotates synchronously with the fan blade 213, so that the sleeving shaft 214 forms a pulling force or a pushing force on the rotating push plate 215, the rotating push plate 215 can drive the pulling rod 211 to displace to the front side or the rear side, so that the first rack 28 slides on the sleeving rod 29, and the first tension spring 210 is stretched or contracted, so that the first rack 28 engages the first gear 27 to repeatedly rotate, and the swing shaft 24 rotates synchronously under the drive of the speed reduction assembly, so that the swing shaft 24 can drive the swing fin 22 to swing.

[0045] At the same time, since the air inlet groove 25 is trumpet-shaped, according to the Venturi effect, when the restricted flow passes through the reduced flow cross section, the flow rate of the fluid increases, the flow rate of the fluid increases, which can ensure the stability of driving the fan blade 213 to rotate.

[0046] The speed reduction assembly comprises a transmission cover 218, the upper surface of the transmission cover 218 is connected with the lower end of the swing shaft 24, the transmission cover 218 is hollow inside, and the lower part is open, the upper end of the connecting shaft 216 extends into the inside of the transmission cover 218 through the opening of the transmission cover 218, the upper end of the connecting shaft 216 is sleeved with a first speed reduction gear 219, and the bottom wall of the speed reduction cavity 217 is rotationally connected with a plurality of second speed reduction gears 220 which extend into the transmission cover 218, the plurality of second speed reduction gears 220 are arranged in a circumferential array on the outer ring of the first speed reduction gear 219 and are rotationally connected with the first speed reduction gear 219, and the inner ring of the transmission cover 218 is provided with an annular tooth 221 which is rotationally connected with the plurality of second speed reduction gears 220. As known from the above, the connecting shaft 216 and the swing shaft 24 are arranged as a planetary gear set, so that the force consumed by the connecting shaft 216 to drive the swing shaft 24 is reduced, and the problem that the airflow cannot drive the fan blade 213 to rotate due to the large force consumed by the driving swing fin 22 to rotate is avoided as much as possible, and the stability of the swing fin 22 in operation is ensured.

[0047] The dustproof net 5 is arranged in the air inlet groove 25, the outer surface of the dustproof net 5 is flush with the outer surface of the fixed fin 21, and the dustproof net 5 limits the dust from entering the air inlet groove 25 along the airflow, so that the problem that the straight groove 26 is blocked by impurities and the swing fin 22 cannot rotate is avoided as much as possible, and the stability of the swing fin 22 in operation is further ensured.

[0048] Although the dustproof net 5 can isolate impurities, the impurities will still adhere to the dustproof net 5, and if not handled for a long time, the impurities will adhere to the dustproof net 5, causing the mesh of the dustproof net 5 to be blocked and affecting the air permeability of the dustproof net 5. Therefore, a knocking assembly is arranged in the air inlet groove 25 to knock the dustproof net 5, the dustproof net 5 is vibrated by the knocking assembly, the impurities adhering to the dustproof net 5 can jump under the vibration, and the impurities are prevented from adhering to the dustproof net 5 for a long time under the action of the airflow. When the vehicle is stationary, the adhesion between the impurities and the dustproof net 5 is low, so that the impurities can fall off under the action of inertia.

[0049] The knocking assembly comprises a knocking head 51, the knocking head 51 is arranged in the air inlet groove 25, the rear surface of the knocking head 51 is provided with a movable rod 52, the outer surface of the movable rod 52 is slidably sleeved with a sleeving seat 53, one side of the sleeving seat 53 is mounted on the inner wall of the air inlet groove 25, the outer surface of the movable rod 52 is sleeved with a connecting plate 54, and the connecting plate 54 and the sleeving seat 53 are provided with a second tension spring 55 which is movably sleeved on the outer surface of the movable rod 52. When the second tension spring 55 is not affected by tension, the second tension spring 55 will form a tension on the connecting plate 54, so that the initial position of the knocking head 51 is not in contact with the dustproof net 5.

[0050] A second rack 56 is provided at the rear end of the movable rod 52, and a sector gear 57 is sleeved on the outer surface of the mounting shaft 212. When the mounting shaft 212 rotates, the sector gear 57 can be meshed and connected with the second rack 56. When in use, the mounting shaft 212 rotates clockwise synchronously with the fan blades 213, and the sector gear 57 rotates with the mounting shaft 212 at the same time. When the sector gear 57 meshes with the second rack 56, the sector gear 57 will form a forward thrust on the second rack 56. At the same time, the movable rod 52 is synchronously displaced to the front side, and the second tension spring 55 is stressed and stretched, so that the knocking head 51 knocks on the dustproof net 5. When the fan gear 57 is not engaged with the second rack 56, the movable rod 52 is pulled to the rear side by the second tension spring 55. At this time, the knocking head 51 is not in contact with the dustproof net 5. Since the fan blades 213 will continue to rotate under the drive of the airflow, the knocking head 51 can continuously knock on the dustproof net 5, thereby avoiding the problem of the dustproof net 5 being blocked by impurities.

[0051] Two flow channels 6 are provided in the fixed fin 21, and both flow channels 6 are continuously curved. A connecting groove 7 connected to the straight groove 26 is provided on the side of the flow channel 6 close to the straight groove 26. When the airflow enters the straight groove 26, the airflow can flow into the flow channel 6 through the connecting groove 7. Since the airflow flows in the flow channel 6, the airflow can take away the heat inside the fixed fin 21, further improving the heat conduction efficiency of the fixed fin 21 to the heat exchange tube 3, thereby ensuring the use effect of the heat treatment device.

[0052] The inner wall of the flow channel 6 on the side away from the straight groove 26 is provided with an air outlet groove 610 extending from the outer surface of the fixed fin 21. A mounting shaft (not shown in the figure) is rotatably connected between the upper and lower inner walls of the air outlet groove 610. A rotating baffle 611 is sleeved on the outer surface of the mounting shaft. A limiting groove 612 communicating with the air outlet groove 610 is provided on the outer surface of the fixed fin 21. A torsion spring (not shown in the figure) is provided between the mounting shaft and the inner wall of the air outlet groove 610. Therefore, under the action of the torsion spring, the rotating baffle The initial position of 611 is rotated into a horizontal shape, and the rear side of the rotating baffle 611 is rotated into the limiting groove 612, so that the rotating baffle 611 can seal the air outlet groove 610, and try to avoid external dust from entering the flow channel 6 through the air outlet groove 610 when the vehicle is stationary. When the air flow flows to the end of the flow channel 6, the air flow will form a thrust on the rotating baffle 611, causing the rotating baffle 611 to rotate outward, and at the same time the torsion spring is deformed, so that the air flow can finally be discharged from the air outlet groove 610.

[0053] The auxiliary heat dissipation assembly is arranged in each horizontal passage of the flow passage 6, and comprises a mounting block 61 mounted on the bottom wall of the horizontal passage of the flow passage 6. One side of the mounting block 61 in the wind surface is provided with an arc-shaped push plate 62. The surface of the arc-shaped push plate 62 towards the mounting block 61 is provided with a sliding rod 63. The mounting block 61 is provided with a sliding cavity 64. The other end of the sliding rod 63 is slidably penetrated into the sliding cavity 64. One end of the sliding rod 63 in the sliding cavity 64 is provided with an embedded sliding plate 65 which slides in the sliding cavity 64. A third tension spring 66 is arranged between the embedded sliding plate 65 and the inner wall of the sliding cavity 64 and is sleeved on the outer surface of the sliding rod 63. When the third tension spring 66 is not pulled, the third tension spring 66 will form a pulling force on the embedded sliding plate 65, so that the initial position of the arc-shaped push plate 62 is away from the mounting block 61. Therefore, the airflow entering the flow passage 6 will form a pushing force on the arc-shaped push plate 62, so that the arc-shaped push plate 62 is displaced towards the mounting block 61. At the same time, the sliding rod 63 pushes the embedded sliding plate 65 to slide in the sliding cavity 64, and the third tension spring 66 is stressed and stretched.

[0054] The horizontal passage of the flow passage 6 is provided with two extension fins 67 which are respectively arranged on the left and right sides of the mounting block 61. The opposite sides of the two extension fins 67 are slidably penetrated out of the outer surface of the fixed fin 21. The materials of the two extension fins 67 are the same as those of the fixed fin 21. The opposite surfaces of the extension fins 67 and the arc-shaped push plate 62 are respectively provided with a hinged seat 68. Two adjacent hinged seats 68 are hingedly connected with a connecting rotating plate 69. When the arc-shaped push plate 62 is away from the mounting block 61, the connecting rotating plate 69 will form a pulling force on the extension fin 67, so that the initial position of the extension fin 67 is extended into the flow passage 6. At the same time, the outer surface of the extension fin 67 is flush with the outer surface of the fixed fin 21. When the vehicle moves at high speed, the airflow entering the flow passage 6 is increased, so that the pushing force on the arc-shaped push plate 62 is increased, and the arc-shaped push plate 62 is displaced towards the mounting block 61. At this time, the arc-shaped push plate 62 will form a pushing force on the connecting rotating plate 69, so that the connecting rotating plate 69 pushes the extension fin 67 to displace out of the fixed fin 21. In this way, the heat dissipation area of the fixed fin 21 is further increased, the heat dissipation efficiency is improved, and the use effect of the heat exchange treatment device is improved.
