Description

Technical Field

[0001] This application relates to the technical field of generator set cooling and heat dissipation, and in particular to a V-shaped heat dissipation device for a generator set. Background Art

[0002] A generator set generally refers to a mechanical device that converts other forms of energy into electrical energy, and is mainly divided into gas generator sets, fuel generator sets, wind turbine generator sets, etc. The cooling system of a generator set is mainly divided into a closed type and an open type. A closed cooling generator set generally uses a radiator to be connected to the internal cooling system of the unit through inlet and outlet water pipes, and through the operation of a fan, forced cooling of the cooling water is implemented to provide the cooling water required when the generator set works.

[0003] In the related art, a V-shaped heat dissipation device for a generator set mainly includes a chassis and a plate-shaped radiator core. The radiator core is a copper tube aluminum fin heat dissipation plate. There are two radiator cores, and the two radiator cores are arranged in a V-shaped structure. A plurality of fans are arranged above the two V-shaped radiator cores, and the plurality of fans are arranged in sequence along the length direction of the radiator core. A bracket is arranged on the chassis, and the upper end of the bracket supports the fans and the radiator core. The end of the radiator core is communicated with a common water chamber. An inlet for the water to be dissipated is arranged at the bottom of the common water chamber, and an outlet for discharging the water after heat dissipation is arranged at the top of the common water chamber. A control cabinet is arranged on the chassis, and a temperature transmitter is arranged at the inlet. The temperature transmitter and the fan are respectively electrically connected to the control cabinet. The control cabinet obtains the inlet water temperature data through the temperature transmitter and controls the rotation speed and start-stop quantity of the fan according to the temperature data. The water to be dissipated enters the common water chamber through the inlet, then enters the radiator core, and the fan takes away the heat on the radiator core. The water after heat dissipation is discharged through the outlet.

[0004] In view of the above related art, the aluminum fins on the radiator core are fixed on the copper tube, and it is not convenient to adjust the heat dissipation area of the radiator core according to needs such as the inlet water temperature. Summary of the Invention

[0005] To facilitate adjusting the heat dissipation area of the radiator core as needed, this application provides a V-shaped heat dissipation device for a generator set.

[0006] A V-shaped heat dissipation device for a generator set provided by this application adopts the following technical solutions:

[0007] A V-shaped heat dissipation device for a generator set, comprising a bottom plate, radiator cores arranged on both sides of the bottom plate, and a plurality of fans arranged on the bottom plate. The fans are located above the radiator cores and between the radiator cores on both sides. The radiator core includes heat dissipation tubes erected on the bottom plate and multiple fin groups arranged on the heat dissipation tubes. The fin groups correspond to the fans one by one. The fin group includes a plurality of heat dissipation fins. The plurality of heat dissipation fins are located on both sides of the heat dissipation tube in the length direction. The heat dissipation fins are slidably arranged in a direction approaching or departing from the heat dissipation tube. The sliding direction of the heat dissipation fins is perpendicular to the length direction of the heat dissipation tube. The heat dissipation fins are used to abut against the heat dissipation tube. An adjusting component is arranged on the heat dissipation tube. The adjusting component corresponds to the fin group one by one. The adjusting component is used to drive the heat dissipation fins in the corresponding fin group to slide in a direction approaching or departing from the heat dissipation tube.

[0008] By adopting the above technical solution, the adjusting component drives the heat dissipation fins in the corresponding fin group to slide in a direction approaching the heat dissipation tube, so that the heat dissipation fins are closely attached to the outer wall of the heat dissipation tube, which helps to conduct the heat on the heat dissipation tube, and thus the heat dissipation area of the radiator core can be enlarged as needed; by driving the heat dissipation fins in the corresponding fin group to slide in a direction departing from the heat dissipation tube by the adjusting component, the heat dissipation fins are separated from the heat dissipation tube, so that the heat dissipation area of the radiator core can be reduced as needed, which provides convenience for adjusting the heat dissipation area of the radiator core as needed.

[0009] Preferably, a plurality of sets of sleeve plate groups are sleeved on the heat dissipation tube. The sleeve plate groups correspond to the fin groups one by one. Each set of sleeve plate groups includes two fixing plates sleeved on the heat dissipation tube at intervals. The heat dissipation fins of the fin group are located between the two fixing plates of the corresponding sleeve plate group. Each adjusting component includes a bidirectional screw, a sliding plate, and a driving member arranged on the bidirectional screw. The bidirectional screw is rotatably arranged on the fixing plate corresponding to the fin group. The rotation axis of the bidirectional screw is parallel to the sliding direction of the heat dissipation fins. There are two sliding plates. The heat dissipation tube is located between the two sliding plates. The sliding plates are located between the two fixing plates of the corresponding sleeve plate group. The sliding plates are threadedly sleeved on the bidirectional screws of the two fixing plates. The plurality of heat dissipation fins on the same side of the heat dissipation tube are arranged on the sliding plate on the corresponding side. The driving member is used to drive the bidirectional screws on the two fixing plates of the sleeve plate group to rotate.

[0010] By adopting the above technical solution, the driving member drives the bidirectional screws on the two fixing plates of the sleeve plate group to rotate. The bidirectional screws drive the sliding plates on both sides of the heat dissipation tube to approach or separate from each other, so that the sliding plates drive the plurality of heat dissipation fins on the corresponding side to slide in a direction approaching or departing from the heat dissipation tube, which helps to realize the abutment or separation of the heat dissipation fins and the heat dissipation tube, and further facilitates adjusting the heat dissipation area of the radiator core as needed.

[0011] Preferably, the driving member includes a first reel sleeved on the bidirectional screw, a transmission rope wound around the first reel, and a torsion spring sleeved on the bidirectional screw. One end of the torsion spring is arranged on the fixed plate, and the other end is arranged on the bidirectional screw. The torsion spring is used to drive the bidirectional screw to reset. A transmission rod is rotatably arranged on the bottom plate. The transmission rod is located between the two side heat dissipation tubes. The transmission rod corresponds to the fan one by one. The transmission rod is directly below the corresponding fan. The rotation axis of the transmission rod is parallel to the rotation axis of the blades of the corresponding fan. A fan blade is coaxially arranged on the transmission rod. A second reel is sleeved on the transmission rod. The ends of the transmission ropes on the bidirectional screws corresponding to both sides of the fan, which are far away from the first reel, are both wound around the second reel and in the same winding direction. When the wind of the fan blows the fan blade to rotate, the second reel rotates to wind up the transmission rope; when the first reel rotates to unwind the transmission rope, the bidirectional screw drives the two sliding plates to approach each other.

[0012] By adopting the above technical solution, when the fan corresponding to the fin group works, the wind blown by the fan blows onto the fan blade at the corresponding position, driving the fan blade to drive the transmission rod and the second reel to rotate, so that the second reel winds up the transmission rope. The transmission rope pulls the first reel to rotate and unwind the transmission rope. At this time, the torsion spring deforms. The first reel drives the corresponding bidirectional screw to rotate, so that the sliding plates at both ends of the bidirectional screw drive the corresponding plurality of heat dissipation fins to slide towards the direction close to the heat dissipation tube, which helps to make the heat dissipation fins close to the heat dissipation tube, and is convenient to expand the heat dissipation area of the radiator core according to needs; when the fan stops working, the torsion spring drives the bidirectional screw to rotate in the reverse direction to reset, so that the first reel winds up the transmission rope, and the sliding plates at both ends of the bidirectional screw drive the corresponding plurality of heat dissipation fins to slide towards the direction away from the heat dissipation tube, which helps to separate the heat dissipation fins from the heat dissipation tube, and then is convenient to reduce the heat dissipation area of the radiator core according to needs.

[0013] Preferably, a mounting plate is slidably arranged on the sliding plate. The mounting plate slides towards the direction close to or away from the heat dissipation tube. The sliding direction of the mounting plate is parallel to the rotation axis of the bidirectional screw. The plurality of heat dissipation fins on the same side of the sliding plate are arranged on the mounting plate on the corresponding side. A push spring is arranged on the sliding plate. The push spring is used to push the mounting plate to slide towards the direction close to the heat dissipation tube. A pull rope is arranged on the side of the mounting plate away from the heat dissipation tube. The pull rope is used to pull the mounting plate to slide towards the direction away from the heat dissipation tube. A winding and unwinding assembly for winding or unwinding the pull rope is arranged on the sliding plate.

[0014] By adopting the above technical solution, the winding and unwinding assembly winds and unwinds the pulling rope, so that the pulling rope pulls the mounting plate to slide away from the heat dissipation pipe, facilitating the detachment of the heat dissipation fins from the heat dissipation pipe and helping to reduce the moving path of the sliding plate; by unwinding the pulling rope through the winding and unwinding assembly, the compressed push spring has a thrust to push the mounting plate to slide towards the heat dissipation pipe, thereby improving the pressing effect between the heat dissipation fins and the heat dissipation pipe and helping to ensure the heat dissipation effect.

[0015] Preferably, the winding and unwinding assembly includes a third reel rotatably arranged on the sliding plate and a rotating member arranged on the third reel. The rotation axis of the third reel is perpendicular to the rotation axis of the bidirectional screw. One end of the pulling rope away from the mounting plate is wound around the third reel, and the rotating member is used to rotate the third reel to wind or unwind the pulling rope.

[0016] By adopting the above technical solution, the rotating member drives the third reel to rotate to unwind the pulling rope, so that the compressed push spring has a thrust to push the mounting plate to slide towards the heat dissipation pipe, thereby improving the pressing effect between the heat dissipation fins and the heat dissipation pipe and helping to ensure the heat dissipation effect.

[0017] Preferably, the rotating member includes a first gear sleeved on the third reel and a first rack arranged on one side fixing plate. The length direction of the first rack is parallel to the rotation axis of the bidirectional screw. The first gear and the first rack are meshed. When the sliding plate drives the first gear to roll towards the heat dissipation pipe, the third reel rotates to unwind the pulling rope.

[0018] By adopting the above technical solution, when the bidirectional screw rotates to drive the sliding plate to move towards the heat dissipation pipe, the first gear rolls along the first rack towards the heat dissipation pipe, and the first gear drives the third reel to rotate to unwind the pulling rope, so that the compressed push spring has a thrust to push the mounting plate to slide towards the heat dissipation pipe, thereby improving the pressing effect between the heat dissipation fins and the heat dissipation pipe and helping to ensure the heat dissipation effect; when the bidirectional screw rotates to drive the sliding plate to slide away from the heat dissipation pipe, the first gear rolls along the first rack away from the heat dissipation pipe, and the first gear drives the third reel to wind the pulling rope, so that the pulling rope pulls the mounting plate to slide away from the heat dissipation pipe, helping to accelerate the detachment of the heat dissipation fins from the heat dissipation pipe.

[0019] Preferably, a cavity for storing lubricating oil is formed in the sliding plate. The cavity is located above the bidirectional screw. A through hole is formed in the side wall of the sliding plate. The through hole corresponds to the position of the bidirectional screw on the sliding plate. The through hole is communicated with the cavity. A rotating rod is rotatably arranged in the cavity. The rotating rods correspond to the bidirectional screws on the sliding plate one by one. The rotating rod rotatably penetrates through the top wall of the sliding plate. The rotation axis of the rotating rod is perpendicular to the rotation axis of the bidirectional screw. A blocking block for blocking the corresponding through hole is sleeved on the rotating rod. A transmission member is arranged on the fixed plate corresponding to the bidirectional screw for driving the approaching rotating rod to drive the blocking block to rotate towards or away from the through hole.

[0020] By adopting the above technical solution, the transmission member drives the rotating rod and the blocking block to rotate, so that the blocking block intermittently opens the through hole, facilitating the lubricating oil in the cavity to flow to the bidirectional screw through the through hole, thereby contributing to lubricating the bidirectional screw, reducing the friction force, and facilitating the rotation of the fan blade.

[0021] Preferably, the transmission member includes a second rack arranged on the fixed plate corresponding to the bidirectional screw and a second gear sleeved on the rotating rod. The second gear meshes with the approaching second rack. When the torsion spring is in a natural state, the blocking block blocks the corresponding through hole.

[0022] By adopting the above technical solution, when the bidirectional screw rotates to drive the sliding plate to move, the second gear rolls along the second rack. The second gear drives the rotating rod and the blocking block to rotate, so that the blocking block intermittently opens the through hole, facilitating the lubricating oil in the cavity to flow to the bidirectional screw through the through hole, thereby contributing to lubricating the bidirectional screw, reducing the friction force, and facilitating the rotation of the fan blade.

[0023] Preferably, bellows are arranged on both opposite sides of the sliding plate. The through hole is located inside the bellows. The bellows are movably sleeved on the bidirectional screw. One end of the bellows away from the sliding plate is arranged on the side of the bidirectional screw away from the sliding plate.

[0024] By adopting the above technical solution, the arrangement of the bellows makes the lubricating oil flowing out of the through hole not easily fall onto the bottom plate.

[0025] Preferably, an annular groove is formed in the heat dissipation tube. The annular groove corresponds to the heat dissipation fins. The heat dissipation fins are used for fitting and abutting against the corresponding annular groove.

[0026] By adopting the above technical solution, through the fitting and pressing of the heat dissipation fins and the annular groove, it helps to expand the fitting area and ensure the heat dissipation effect.

[0027] In summary, the present application includes the following beneficial technical effects:

[0028] By driving the heat dissipation fins in the corresponding fin group to slide towards the direction close to the heat dissipation pipe through the adjusting component, the heat dissipation fins are tightly attached to the outer wall of the heat dissipation pipe, which helps to conduct the heat on the heat dissipation pipe, so that the heat dissipation area of the radiator core can be expanded as needed; by driving the heat dissipation fins in the corresponding fin group to slide towards the direction away from the heat dissipation pipe through the adjusting component, the heat dissipation fins are separated from the heat dissipation pipe, so that the heat dissipation area of the radiator core can be reduced as needed, providing convenience for adjusting the heat dissipation area of the radiator core as needed.

Detailed Description of the Embodiment

[0035] The following will further describe the present application in detail Figures 1-5 with reference to the attached drawings.

[0036] The embodiment of the present application discloses a V-shaped heat dissipation device for a generator set. Refer to Figure 1 and Figure 2The V-shaped heat dissipation device for the generator set includes a bottom plate 1, a radiator core and a fan 2. The cross section of the bottom plate 1 is rectangular. Two radiator cores are symmetrically installed along the center line of the bottom plate 1. The arrangement direction of the two radiator cores is perpendicular to the length direction of the bottom plate 1. The spacing between the two radiator cores gradually increases in the direction away from the bottom plate 1, so that the two radiator cores are in a V-shaped structure, which helps to expand the heat dissipation area. Support columns 21 are relatively fixed on the bottom plate 1. The support columns 21 are located between the radiator cores on both sides. The top ends of the two support columns 21 are connected to the same top plate 22. The top plate 22 is located above the radiator core. The fan 2 is installed on the top plate 22. Multiple fans 2 are installed along the length direction of the bottom plate 1. Multiple fans 2 are located between the radiator cores on both sides, and multiple fans 2 are located above the radiator core.

[0037] Reference Figure 1 and Figure 2 Each radiator core includes a heat dissipation tube 3 and a plurality of fin groups 4 arranged on the heat dissipation tube 3. The heat dissipation tube 3 is mounted on the base plate 1. The heat dissipation tube 3 is a copper tube. The length direction of the heat dissipation tube 3 is parallel to the length direction of the base plate 1. The water inlet and outlet on the heat dissipation tube 3 are used to communicate with the public water chamber. A plurality of sets of plate groups 6 are fixedly sleeved on the heat pipe 3, the plate groups 6 correspond to the fin groups 4 one by one, the fin groups 4 correspond to the positions of the fans 2 one by one, the plurality of plate groups 6 are arranged in sequence along the length direction of the heat pipe 3, the plurality of fin groups 4 are arranged along the length direction of the heat pipe 3, each set of plate groups 6 includes two fixing plates 61 sleeved on the heat pipe 3 at intervals, the spacing between the two fixing plates 61 is adapted to the diameter of the fan 2, so that the fan 2 is located between the two fixing plates 61 of the corresponding plate group 6, the upper end of the fixing plate 61 is inclined in the direction away from the fan 2, so that the plane where the heat pipe 3 is located is inclined, the two fixing plates 61 close to each other of the adjacent plate groups 6 are abutted against each other, the bottom end of the fixing plate 61 is fixedly installed on the base plate 1, the side of the fixing plate 61 away from the fan 2 is fixedly connected with a vertical pole 23, and the pole 23 is fixed on the base plate 1 to support the fixing plate 61 and the heat pipe 3.

[0038] Reference Figure 2 and Figure 3, the fin group 4 includes a plurality of heat dissipation fins 41. The heat dissipation fins 41 are aluminum fins. The plurality of heat dissipation fins 41 are located on both sides of the heat dissipation tube 3 in the length direction. In this embodiment, the plurality of heat dissipation fins 41 are symmetrically distributed in pairs along the length direction of the heat dissipation tube 3. The plurality of heat dissipation fins 41 of the fin group 4 are all located between the two fixing plates 61 of the corresponding sleeve plate group 6. The two symmetric heat dissipation fins 41 are arranged to slide relative to each other. The sliding direction of the heat dissipation fins 41 is perpendicular to the length direction of the heat dissipation tube 3. The heat dissipation fins 41 slide towards or away from the heat dissipation tube 3. An annular groove 20 is formed in the heat dissipation tube 3. The annular groove 20 corresponds to the two symmetric heat dissipation fins 41. An arc groove 24 is formed on the side of the heat dissipation fin 41 close to the heat dissipation tube 3. The arc groove 24 of the heat dissipation fin 41 is used to fit and abut against the side of the corresponding annular groove 20 close to it. The setting of the annular groove 20 helps to improve the heat dissipation effect; an adjusting component 5 is arranged on the heat dissipation tube 3. The adjusting component 5 corresponds to the fin group 4 one by one. The adjusting component 5 is used to drive the heat dissipation fins 41 in the corresponding fin group 4 to slide towards or away from the heat dissipation tube 3.

[0039] Referring to Figure 1 and Figure 2 , a protection plate 25 is fixedly connected between the two vertical rods 23 corresponding to the two fixing plates 61 of the sleeve plate group 6. A plurality of ventilation holes 26 are formed in the protection plate 25. The protection plate 25 helps to protect the radiator core.

[0040] When the control cabinet controls the fan 2 at a specified position to start according to the inlet water temperature data obtained by the temperature transmitter, the adjusting component 5 corresponding to the started fan 2 drives the heat dissipation fins 41 in the corresponding fin group 4 to slide towards the heat dissipation tube 3, so that the arc groove 24 on the heat dissipation fin 41 fits and abuts against the annular groove 20 on the heat dissipation tube 3. The heat on the heat dissipation tube 3 can be conducted to the heat dissipation fins 41 and taken away by the wind force of the fan 2; the adjusting component 5 corresponding to the unstarted fan 2 drives the corresponding heat dissipation fins 41 away from the heat dissipation tube 3, so that the heat dissipation fins 41 are separated from the heat dissipation tube 3, thereby being able to adjust the heat dissipation area of the radiator core according to the need of the inlet water temperature.

[0041] Referring to Figure 3 and Figure 4, to facilitate driving multiple heat dissipation fins 41 of the fin group 4 to slide towards or away from the heat dissipation tube 3, an installation block 27 is fixed on the top wall of the fixing plate 61. The installation block 27 is aligned with the position of the heat dissipation tube 3. The adjusting assembly 5 includes a bidirectional screw 51, a sliding plate 52, and a driving member 53 arranged on the bidirectional screw 51. The bidirectional screw 51 rotatably penetrates through the installation blocks 27 of the fixing plates 61 on both sides of the fin group 4. The rotation axis of the bidirectional screw 51 is perpendicular to the length direction of the heat dissipation tube 3. The threads on both sides of the bidirectional screw 51 located on both sides of the installation block 27 are opposite. The length direction of the sliding plate 52 is parallel to the length direction of the heat dissipation tube 3. There are two sliding plates 52. The heat dissipation tube 3 is located between the two sliding plates 52. The sliding plate 52 is located between the fixing plates 61 on both sides. The sliding plate 52 is threadedly sleeved on the ends of the bidirectional screws 51 on both sides, so that the ends on the same side of the two bidirectional screws 51 are threadedly connected to the same sliding plate 52. The sliding plate 52 is located on the side of the corresponding heat dissipation fin 41 away from the heat dissipation tube 3. An installation plate 10 is arranged on the side of the sliding plate 52 close to the heat dissipation tube 3. The length direction of the installation plate 10 is parallel to the length direction of the sliding plate 52. Multiple heat dissipation fins 41 on the same side of the heat dissipation tube 3 are all fixed on the surface of the corresponding installation plate 10 close to the heat dissipation tube 3. The driving member 53 is used to drive the two bidirectional screws 51 of the sleeve plate group 6 to rotate.

[0042] Refer to Figure 3 and Figure 4 , to facilitate driving the two corresponding bidirectional screws 51 of the sleeve plate group 6 to rotate, a support plate 28 is fixed on the installation block 27. The cross-section of the support plate 28 is T-shaped. The support plate 28 is located above the installation block 27. A connecting plate 29 is fixed at one end of the support plate 28 close to the blower 2. One end of the bidirectional screw 51 close to the blower 2 rotates on the connecting plate 29. The driving member 53 includes a first reel 531, a transmission rope 532, and a torsion spring 533. The first reel 531 is coaxially and fixedly sleeved on one end of the bidirectional screw 51 close to the blower 2. The first reel 531 is located on the side of the sliding plate 52 close to the blower 2. One end of the transmission rope 532 is wound around the first reel 531. The torsion spring 533 is movably sleeved on one end of the bidirectional screw 51 close to the blower 2. The torsion spring 533 is located on the side of the first reel 531 close to the blower 2. One end of the torsion spring 533 is fixed on the connecting plate 29, and the other end is fixed on the side wall of the first reel 531. The torsion spring 533 is used to drive the corresponding bidirectional screw 51 to reset. The torsion force of the torsion spring 533 is greater than the sum of the rotational friction of the transmission rod 7 and the rotational friction of the bidirectional screw 51.

[0043] Refer to Figure 2 and Figure 3, a transmission rod 7 is rotatably arranged on the bottom plate 1. The transmission rods 7 correspond to the blowers 2 one by one. The transmission rod 7 is located between the radiator cores on both sides. The transmission rod 7 is directly below the corresponding blower 2. The rotation axis of the blower 2 blades is arranged in the vertical direction. The rotation axis of the transmission rod 7 is parallel to the rotation axis of the corresponding blower 2 blades. A fan blade 8 is coaxially fixed at the top end of the transmission rod 7. The fan blade 8 is directly below the corresponding blower 2. A second reel 9 is fixedly sleeved on the transmission rod 7. The second reel 9 is located below the fan blade 8. One ends of the transmission ropes 532 on the corresponding bidirectional screws 51 on both sides of the blower 2, which are far away from the first reel 531, are wound around the second reel 9 and have the same winding direction. When the wind of the blower 2 blows the fan blade 8 to rotate, the second reel 9 rotates to wind up the transmission rope 532; when the first reel 531 rotates to unwind the transmission rope 532, the bidirectional screw 51 drives the two sliding plates 52 to approach each other. In other embodiments, the driving member 53 can be replaced by a reduction motor installed on the connecting plate 29. The bidirectional screw 51 is coaxially fixed to the output end of the corresponding reduction motor. The reduction motor is electrically connected to the control cabinet. The bidirectional screw 51 can also be driven to rotate by the reduction motor.

[0044] When the control cabinet controls the blower 2 at the required position to start according to the inlet water temperature data obtained by the temperature transmitter, the started blower 2 blows the wind onto the fan blade 8 below, driving the corresponding fan blade 8 to drive the transmission rod 7 and the second reel 9 to rotate, so that the second reel 9 winds up the corresponding transmission rope 532. The transmission rope 532 pulls the corresponding first reel 531 to rotate and unwind the transmission rope 532. The first reel 531 drives the bidirectional screw 51 to rotate, causing the torsion spring 533 to be torsionally deformed. Then, the rotating bidirectional screw 51 drives the two sliding plates 52 at both ends to approach each other, causing the mounting plate 10 to drive the corresponding plurality of heat dissipation fins 41 to approach the heat dissipation tube 3, so that the arc-shaped grooves 24 on the heat dissipation fins 41 are in close contact with the annular grooves 20 on the heat dissipation tube 3, which helps the heat dissipation tube 3 transfer heat to the heat dissipation fins 41, and the heat is taken away by the wind blown out by the blower 2; since the unstarted blower 2 cannot blow the corresponding fan blade 8 to rotate, under the action of the torsion spring 533, the sliding plates 52 on the bidirectional screw 51 remain in a state away from the heat dissipation tube 3, causing the corresponding heat dissipation fins 41 to be separated from the heat dissipation tube 3, and thus the heat dissipation area of the radiator core can be adjusted according to the need of the inlet water temperature.

[0045] Refer to Figure 3 and Figure 4, Guide rods 30 are fixed to the opposite sides of the lower ends of the two fixing plates 61 of the template set 6. The length direction of the guide rods 30 is parallel to the rotation axis of the mounting plate 10. A same guide plate 31 is slidably sleeved on the two guide rods 30 on the same side of the two fixing plates 61. The sliding direction of the guide plate 31 is parallel to the sliding direction of the mounting plate 10. The guide plate 31 is located on the side of the heat dissipation fins 41 away from the heat dissipation tube 3. The sides of the plurality of heat dissipation fins 41 on the same side of the heat dissipation tube 3 in the fin group 4 away from the heat dissipation tube 3 are fixed to the guide plate 31. The sliding fit between the guide plate 31 and the guide rods 30 helps to guide the sliding of the mounting plate 10.

[0046] Refer to Figure 3 and Figure 4 , The mounting plate 10 is slidably arranged on the corresponding sliding plate 52. The sliding direction of the mounting plate 10 is parallel to the rotation axis of the bidirectional screw 51. The mounting plate 10 slides in the direction of approaching or departing from the heat dissipation tube 3. Slide rods 32 are fixed to the opposite sides of the side of the mounting plate 10 close to the sliding plate 52. Sleeve rods 33 are fixed to the side of the sliding plate 52 close to the mounting plate 10. The sleeve rods 33 correspond to the slide rods 32 one by one. The slide rods 32 are slidably connected to the corresponding sleeve rods 33. The sliding direction of the slide rods 32 is parallel to the sliding direction of the mounting plate 10. A push spring 11 is movably sleeved on the sleeve rod 33. One end of the push spring 11 is fixed to the side of the mounting plate 10 away from the heat dissipation fins 41, and the other end is fixed to the side of the sliding plate 52 close to the mounting plate 10. The push spring 11 is used to push the mounting plate 10 to slide in the direction of approaching the heat dissipation tube 3. A pull rope 12 is fixedly connected to the side of the slide rod 32 away from the mounting plate 10. The pull rope 12 slidably passes through the corresponding sliding plate 52. The pull rope 12 is used to pull the mounting plate 10 to slide in the direction of departing from the heat dissipation tube 3. A winding or unwinding assembly 13 for winding or unwinding the pull rope 12 is arranged on the sliding plate 52.

[0047] Refer to Figure 3 and Figure 4, to facilitate the winding or unwinding of the pulling rope 12, the winding and unwinding assembly 13 includes a third reel 131 and a rotating member 132. The third reels 131 correspond to the pulling ropes 12 one by one. The third reel 131 is rotatably arranged on the side of the sliding plate 52 away from the mounting plate 10. The rotation axis of the third reel 131 is perpendicular to the rotation axis of the bidirectional screw 51. The third reel 131 is located between the bidirectional screws 51 on both sides of the sliding plate 52. One end of the pulling rope 12 away from the mounting plate 10 is wound around the corresponding third reel 131. The rotating member 132 is arranged on the sliding plate 52 and is used to rotate the third reel 131 to wind or unwind the pulling rope 12. The rotating member 132 includes a first gear 1321 and a first rack 1322. The first gear 1321 is coaxially sleeved on the rotating shaft of the third reel 131. The first gear 1321 is located above the third reel 131. The first rack 1322 is fixedly arranged on the side wall of the support plate 28. The length direction of the first rack 1322 is parallel to the rotation axis of the bidirectional screw 51. The first gear 1321 meshes with the first rack 1322 on the adjacent support plate 28. When the sliding plate 52 drives the first gear 1321 to roll towards the direction close to the heat dissipation tube 3, the third reel 131 rotates to unwind the pulling rope 12.

[0048] When the bidirectional screw 51 rotates to drive the sliding plates 52 on both sides to slide towards the direction close to the heat dissipation tube 3, the sliding plate 52 drives the first gear 1321 on the third reel 131 to roll along the first rack 1322 towards the direction close to the heat dissipation tube 3. The first gear 1321 drives the corresponding third reel 131 to rotate, and the third reel 131 unwinds the pulling rope 12. At this time, the compressed push spring 11 has a thrust on the mounting plate 10, so that the heat dissipation fins 41 can be tightly pressed against the heat dissipation tube 3, improving the heat dissipation effect; when the bidirectional screw 51 rotates to drive the sliding plates 52 on both sides to slide towards the direction away from the heat dissipation tube 3, the first gear 1321 rolls along the first rack 1322 towards the direction away from the heat dissipation tube 3, and the first gear 1321 drives the third reel 131 to reverse, so that the third reel 131 winds the pulling rope 12, which helps to accelerate the separation between the heat dissipation fins 41 and the heat dissipation tube 3 and reduces the moving distance of the sliding plate 52.

[0049] Refer to Figure 4 and Figure 5, a cavity 14 for storing lubricating oil is formed in the sliding plate 52. The cavity 14 is located above the bidirectional screw 51. Through holes 15 are formed in the opposite two side walls of the sliding plate 52. The through holes 15 correspond to the position of the bidirectional screw 51 and are communicated with the cavity 14. Rotating rods 16 are rotatably arranged on both sides in the cavity 14. The rotating rods 16 rotatably penetrate through the top wall of the sliding plate 52. The rotating rods 16 correspond to the bidirectional screw 51 one by one. The two support plates 28 of the sleeve plate group 6 are located between the two rotating rods 16 of the sliding plate 52. One end of the rotating rod 16 located in the cavity 14 is fixedly sleeved with a blocking block 17 for blocking the corresponding through hole 15 on one side. The blocking block 17 is a rubber block. The cross-section of the blocking block 17 is oval. The long side diameter of the blocking block 17 is adapted to the width of the cavity 14, and the long side diameter of the blocking block 17 is smaller than the length of the cavity 14, so that the rotating rod 16 can rotate 360°. A transmission member 18 for driving the adjacent rotating rod 16 to drive the blocking block 17 to rotate towards or away from the through hole 15 is arranged on the support plate 28 close to the bidirectional screw 51.

[0050] Referring to Figure 4 and Figure 5 , for facilitating driving the rotating rod 16 to drive the blocking block 17 to rotate, the transmission member 18 includes a second rack 181 and a second gear 182. The second rack 181 is fixed on the side of the support plate 28 away from the first rack 1322. The second gear 182 is fixedly sleeved on the end of the rotating rod 16 located outside the cavity 14. The second gear 182 and the second rack 181 are meshed. When the torsion spring 533 is in a natural state, the blocking block 17 blocks the corresponding through hole 15.

[0051] When the bidirectional screw 51 rotates to drive the sliding plates 52 on both sides to slide towards or away from the heat dissipation pipe 3, the sliding plate 52 drives the second gear 182 to roll along the second rack 181. The second gear 182 drives the rotating rod 16 to rotate. The rotating rod 16 drives the blocking block 17 to rotate, so that the blocking block 17 intermittently opens the through hole 15, which helps the lubricating oil in the cavity 14 to flow onto the bidirectional screw 51. The lubricating oil can lubricate the bidirectional screw 51, reduce the friction force, and facilitate the rotation of the fan blade 8.

[0052] Referring to Figure 3 and Figure 5 , bellows 19 are fixed on both opposite sides of the sliding plate 52. The through holes 15 are located inside the bellows 19. The bellows 19 are movably sleeved on the bidirectional screw 51. The bellows 19 extend towards the direction away from the sliding plate 52. One end of the bellows 19 away from the sliding plate 52 is fixed on the side of the bidirectional screw 51 away from the sliding plate 52. The bellows 19 can prevent the lubricating oil flowing out of the through hole 15 from easily falling onto the bottom plate 1.

[0053] The implementation principle of the embodiments of this application is as follows: When the control cabinet starts the fan 2 at a specified position according to the inlet water temperature data obtained by the temperature transmitter, the started fan 2 blows the wind onto the lower fan blades 8, driving the corresponding fan blades 8 to drive the transmission rod 7 and the second reel 9 to rotate, so that the second reel 9 winds up the corresponding transmission rope 532, and the transmission rope 532 pulls the corresponding first reel 531 and the bidirectional screw 51 to rotate. Then, the rotating bidirectional screw 51 drives the sliding plates 52 at both ends to approach each other. At this time, the first gear 1321 rolls along the first rack 1322 towards the direction close to the heat dissipation pipe 3, and the second gear 182 rolls along the second rack 181. The first gear 1321 drives the third reel 131 to rotate and unwind the pulling rope 12, and the blocking block 17 rotates to open the through hole 15 so that the lubricating oil in the cavity 14 flows onto the bidirectional screw 51. At this time, the push spring 11 can push the mounting plate 10 to drive the corresponding plurality of heat dissipation fins 41 close to the heat dissipation pipe 3. Under the thrust of the push spring 11, the arc-shaped groove 24 on the heat dissipation fin 41 fits and abuts tightly against the annular groove 20 on the heat dissipation pipe 3, which helps the heat dissipation pipe 3 transfer heat to the heat dissipation fins 41, and the heat is taken away by the wind blown by the fan 2.

[0054] Since the unstarted fan 2 cannot drive the corresponding fan blade 8 to rotate, under the action of the torsion spring 533, the sliding plate 52 on the bidirectional screw 51 remains in a state of being away from the heat dissipation pipe 3, so that the corresponding heat dissipation fin 41 is separated from the heat dissipation pipe 3, and thus the heat dissipation area of the radiator core can be adjusted as needed.

[0055] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
