Description

Technical Field

[0001] The present invention relates to the technical field of heat exchangers, and more particularly to a circulating heat exchange processing device for a vehicle refrigeration system. Background Art

[0002] The automotive heat exchanger is a special component in the automotive engine cooling system. Its main function is to transfer heat from the engine compartment to the outside, so that the engine can work normally and avoid overheating, melting or scrapping. It can be regarded as a fully enclosed small heat exchange system for heat exchange between the engine compartment and the external environment, and for isolating steam and cooling media.

[0003] Existing automotive heat exchangers are generally of the tube-fin type. The core of the exchanger is composed of many thin cooling tubes and fins. The cooling tubes mostly adopt an oblate cross-section to reduce air resistance and increase the heat transfer area. When the vehicle is running, the heat in the cooling tubes is transferred to the fins. The airflow passes through the gaps between the fins and is eventually carried away by the airflow, completing the heat exchange between the coolant, air and fins.

[0004] However, the heat sinks on most existing automotive heat exchangers are generally fixed. When the vehicle is running at high speed, the airflow will generate severe turbulence between the fixed heat sinks, and the wind resistance increases with the square of the vehicle speed. When the vehicle is running at low speed and relying only on the fan airflow, a laminar boundary layer is easily formed on the surface of the fixed heat sink, and the heat exchange efficiency drops sharply, affecting the use effect of the automotive heat exchanger.

Since the air flow flows in the flow channel, the air flow can take away the heat inside the fixed fins, further improving the heat conduction efficiency of the fixed fins to the heat exchange tubes. At the same time, when the vehicle is running at high speed, the extended fins can push out the fixed fins, which further increases the heat dissipation area of ​​the fixed fins, improves the heat dissipation efficiency, and improves the use effect of the heat exchange treatment device.

[0020] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0022] In the present invention, unless otherwise specified, directions such as "up" and "down" are generally used with respect to the directions shown in the drawings, or with respect to the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "left" and "right" are generally used with respect to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.

[0023] See also Figure 1-8 , the present invention provides the following technical solutions: Specifically, it refers to a circulating heat exchange processing device for a vehicle refrigeration system, including a frame 1, in which a plurality of heat dissipation fins 2 arranged in parallel at intervals are arranged, and a heat exchange tube 3 arranged in a continuous bending manner is inlaid on the frame 1. At the same time, a plurality of heat dissipation fins 2 are sleeved on the outer surface of the heat exchange tube 3 located in the frame 1, and the heat dissipation fins 2 and a section of the heat exchange tube 3 located in the frame 1 are made of high thermal conductivity materials. Flange joints 4 are provided at both ends of the heat exchange tube 3, which are connected to the vehicle's refrigeration pipeline through the flange joints 4. When the vehicle is running, the pump body transports the coolant into the heat exchange tube 3, and the coolant passes through the continuously bent heat exchange tube 3, so that the heat in the coolant is conducted to the heat dissipation fins 2 through the heat exchange tube 3. At the same time, the external cold air blows to the heat dissipation fins 2 through the vehicle grille, and the airflow flowing between the two adjacent heat dissipation fins 2 can take away the heat, thereby achieving the purpose of heat exchange of the coolant in the heat exchange tube 3.

[0024] The heat dissipation fin 2 includes a fixed fin 21, which is installed on the outer surface of the heat exchange tube 3 located in the frame 1. A U-shaped swinging fin 22 is provided on the rear side of the fixed fin 21. Grooves 23 are provided on the upper and lower surfaces of the rear side of the fixed fin 21. The upper and lower protrusions of the swinging fin 22 extend into the two grooves 23 respectively. A swing shaft 24 is provided between the groove 23 and the protrusion of the swinging fin 22. The swing shaft 24 is rotatably connected to the inner wall of the groove 23. Therefore, when in use, the swinging fin 22 swings with the swing shaft 24 as the rotation point. In this way, when the vehicle is running at high speed, it is aerodynamically self-smoothed, and the high-speed airflow is adsorbed and adheres to the surface of the swinging fin 22 to form an aviation-like laminar shape, which can reduce wind resistance to a certain extent. At the same time, when the vehicle is running at low speed, the swinging fin 22 destroys the laminar boundary layer located at the fixed fin 21, generates tail vortex mixing, and further improves the heat dissipation efficiency of the vehicle when running at low speed.

[0025] When in use, the front of the fixed fin 21 is the windward side, which keeps the main structure stable and avoids overall vibration. At the same time, the swinging fin 22 is set on the leeward side, and the leeward swing amplitude is constrained by physical limits, eliminating the risk of air duct blockage due to uncontrolled swinging.

[0026] The front of the fixed fin 21 is provided with two air inlet slots 25 which are arranged in parallel up and down. The air inlet slot 25 is trumpet-shaped, and a straight slot 26 is provided on the rear side of the air inlet slot 25. The bottom wall of the upper straight slot 26 is rotatably connected to a connecting shaft 216. The outer surface of the connecting shaft 216 is sleeved with a first gear 27, and the outer surface of the first gear 27 is meshedly connected to a first rack 28. A sleeve rod 29 is provided on the inner wall of the rear side of the straight slot 26. A sliding groove (not shown in the figure) is provided on the surface of the first rack 28 close to the sleeve rod 29. The first rack 28 is slidably sleeved on the outer surface of the sleeve rod 29 through the sliding groove. A first tension spring 210 which is movably sleeved on the outer surface of the sleeve rod 29 is provided between the first rack 28 and the inner wall of the straight slot 26. When the first tension spring 210 is not affected by the tension, the first tension spring 210 pulls the first rack 28 close to the inner wall of the rear side of the straight slot 26.

[0027] A deceleration chamber 217 is opened on the upper side of the fixed fin 21, the upper end of the connecting shaft 216 rotates and passes through the deceleration chamber 217, and the lower end of the upper swing shaft 24 also rotates and passes through the deceleration chamber 217. A deceleration assembly is arranged between the connecting shaft 216 and the swing shaft 24.

[0028] When the vehicle stops running, the first tension spring 210 pulls the first rack 28 to be located at the rear side near the straight slot 26, so the swing shaft 24 swings the swing fin 22 to an initial state of tilting. Figure 4, making the air duct between the two fixed fins 21 inclined. When the vehicle is cold-started in a low-temperature environment, the low-speed airflow during cold start cannot drive the swing fins 22 to swing, and the swing fins 22 maintain an inclined state, which can reduce the heat dissipation efficiency of the fixed fins 21, thereby improving the warm-up efficiency of the vehicle during cold start in a low-temperature environment, and further reducing the fuel consumption of the vehicle during cold start.

[0029] A mounting shaft 212 is rotatably connected to the right inner wall of the air inlet slot 25, and a fan blade 213 is provided at the left end of the mounting shaft 212. A sleeve shaft 214 is provided on the left surface of the fan blade 213, and the sleeve shaft 214 is provided at an eccentric position of the circular surface of the fan blade 213. A pulling rod 211 is provided on the front surface of the first rack 28, and the front end of the pulling rod 211 extends into the air inlet slot 25. A rotating push plate 215 is rotatably sleeved on the outer surface of the sleeve shaft 214, and the other side of the rotating push plate 215 is hinged to the front end of the pulling rod 211.

[0030] When the vehicle is driving, the airflow blows toward the windward side of the fixed fin 21, and part of the airflow will enter the air inlet slot 25. The airflow will form a thrust on the blades 213. At the same time, the mounting shaft 212 rotates synchronously with the blades 213. At this time, the sleeve shaft 214 rotates synchronously with the blades 213, so the sleeve shaft 214 will form a pulling force or a thrust on the rotating push plate 215. The rotating push plate 215 can drive the pulling rod 211 to move forward or backward, so that the first rack 28 slides on the sleeve rod 29, and the first tension spring 210 stretches or contracts, so that the first rack 28 engages and transmits the first gear 27 to rotate repeatedly, and the swing shaft 24 rotates synchronously driven by the deceleration component, so the swing shaft 24 can drive the swing fin 22 to swing.

[0031] At the same time, since the air inlet slot 25 is trumpet-shaped, according to the Venturi effect, when the restricted flow passes through the reduced flow section, the fluid flow rate increases, and the increased fluid flow rate can ensure the stability of the rotation of the driving blades 213.

[0032] The reduction assembly includes a transmission cover 218, the upper surface of the transmission cover 218 is connected to 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 transmission cover 218 through the opening of the transmission cover 218, the upper end of the connecting shaft 216 is sleeved with a first reduction gear 219, and the bottom wall of the reduction cavity 217 is rotatably connected to a plurality of second reduction gears 220 that extend into the transmission cover 218. The plurality of second reduction gears 220 are arranged in a circumferential array on the first reduction gear 219. The outer ring of the gear 219 is meshed with the first reduction gear 219, and the inner ring of the transmission cover 218 is provided with annular teeth 221 meshed with multiple second reduction gears 220. From the above, it can be seen that a planetary gear set is set between the connecting shaft 216 and the swing shaft 24, which reduces the force spent by the connecting shaft 216 to drive the swing shaft 24, and avoids the problem of spending a lot of force to drive the swing fins 22 to rotate, resulting in the airflow being unable to drive the fan blades 213 to rotate, thereby ensuring the stability of the operation of the swing fins 22.

[0033] A dustproof net 5 is provided in the air inlet slot 25. The outer surface of the dustproof net 5 is flush with the outer surface of the fixed fin 21. The restriction of the dustproof net 5 prevents dust from entering the air inlet slot 25 along the air flow, and avoids the problem of the straight slot 26 being blocked by impurities, which causes the swing fin 22 to be unable to rotate, further ensuring the stability of the operation of the swing fin 22.

[0034] Although the dust-proof net 5 can isolate impurities, these impurities will still adhere to the dust-proof net 5. If they are not handled for a long time, the impurities will adhere to the dust-proof net 5, causing the mesh of the dust-proof net 5 to be blocked, affecting the air permeability of the dust-proof net 5. Therefore, a knocking component for knocking the dust-proof net 5 is provided in the air inlet slot 25. The knocking component continuously knocks the dust-proof net 5 to vibrate the dust-proof net 5, so that the impurities attached to the dust-proof net 5 can jump under the action of vibration, and the impurities are avoided from being blown by the airflow for a long time and attached to the dust-proof net 5. In this way, when the vehicle is stationary, the adhesion between the impurities and the dust-proof net 5 is low, so that the impurities can fall off under the action of inertia.

[0035] The knocking assembly includes a knocking head 51, which is arranged in the air inlet groove 25. A movable rod 52 is provided on the rear surface of the knocking head 51. The outer surface of the movable rod 52 is slidably sleeved with a sleeve seat 53. One side of the sleeve seat 53 is installed 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. A second tension spring 55 that is movably sleeved on the outer surface of the movable rod 52 is provided between the connecting plate 54 and the sleeve seat 53. When the second tension spring 55 is not affected by the 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] Each horizontal section of the flow channel 6 is provided with an auxiliary heat dissipation component, which includes a mounting block 61. The mounting block 61 is mounted on the bottom wall of the horizontal channel of the flow channel 6. An arc-shaped push plate 62 is provided on the windward side of the mounting block 61. A sliding rod 63 is provided on the surface of the arc-shaped push plate 62 facing the mounting block 61. A sliding cavity 64 is provided in the mounting block 61. The other end of the sliding rod 63 slides through the sliding cavity 64. One end of the sliding rod 63 located in the sliding cavity 64 is provided with a built-in slide 65 that slides in the sliding cavity 64. The built-in slide A third tension spring 66 movably mounted on the outer surface of the sliding rod 63 is provided between the plate 65 and the inner wall of the sliding cavity 64. When the third tension spring 66 is not pulled, the third tension spring 66 will generate a pulling force on the built-in slide plate 65, so that the initial position of the arc-shaped push plate 62 is to the side away from the mounting block 61. Therefore, the airflow entering the flow channel 6 will generate a thrust on the arc-shaped push plate 62, so that the arc-shaped push plate 62 is displaced toward the side close to the mounting block 61. At the same time, the sliding rod 63 pushes the built-in slide plate 65 to slide in the sliding cavity 64, and the third tension spring 66 is stressed and stretched.

[0040] Two extended fins 67 are provided in the horizontal channel of the flow channel 6. The two extended fins 67 are respectively provided on the left and right sides of the mounting block 61. The opposite sides of the two extended fins 67 slide through the outer surface of the fixed fin 21. At the same time, the material of the two extended fins 67 is the same as that of the fixed fin 21. The extended fins 67 and the opposite surfaces of the arc-shaped push plate 62 are provided with hinge seats 68. A connecting rotating plate 69 is hinged between the two adjacent hinge seats 68. When the arc-shaped push plate 62 is on the side away from the mounting block 61, the connecting rotating plate 69 will form a pulling force on the extended fin 67, so that the extended fin 6 The initial position of 7 is to extend into the flow channel 6, and the outer surface of the extended 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 channel 6 increases, thereby increasing the thrust on the arc-shaped push plate 62, causing the arc-shaped push plate 62 to move toward the side close to the mounting block 61. At this time, the arc-shaped push plate 62 will form a thrust on the connecting rotating plate 69, causing the connecting rotating plate 69 to push the extended fin 67 out of the fixed fin 21, thereby further increasing the heat dissipation area of ​​the fixed fin 21, improving the heat dissipation efficiency, and improving the use effect of the heat exchange treatment device.
