Description

Technical Field

[0001] This invention relates to the field of aluminum recycling and manufacturing technology, and in particular to an aluminum profile manufacturing apparatus. Background Technology

[0002] With my country's large-scale infrastructure investment and rapid industrialization, the output and consumption of aluminum profiles have grown rapidly, making my country the world's largest aluminum profile production base and consumer market. Along with the large-scale production of aluminum profiles, a large amount of scrap aluminum is also generated. Recycling and recasting this scrap aluminum will effectively reduce resource consumption and has excellent energy-saving and environmental protection effects.

[0003] In the manufacturing of aluminum profiles, recycled scrap aluminum needs to be added to a hot melt tank for melting. The molten aluminum is then poured into a mold and cooled to set. During the melting process, the scrap aluminum has different shapes, which results in large gaps between the scrap aluminum, making it difficult to heat efficiently. Furthermore, after heating, some impurities remaining in the scrap aluminum are difficult to float to the surface of the liquid, thus affecting the final quality of the aluminum profile. Summary of the Invention

[0004] The purpose of this invention is to solve the problem in the prior art that scrap aluminum is difficult to heat efficiently, thus affecting the final quality of aluminum profiles, and to propose an aluminum profile manufacturing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An aluminum profile manufacturing process includes the following steps:

[0007] Step 1: Crush the recycled aluminum metal;

[0008] Step 2: Melt the crushed aluminum metal.

[0009] Step 3: Allow most of the impurities in the molten metal to float to the surface of the solution;

[0010] Step 4: Pour molten aluminum into a mold for shaping;

[0011] Step 5: Cool the mold using crushed aluminum metal.

[0012] An aluminum profile manufacturing apparatus includes a frame and further includes: a hot melt tank having a feed port and a discharge pipe, fixedly mounted on the frame, wherein a lower mold is fixedly mounted on the frame, and an upper mold is mounted on the lower mold via a lifting device, the output end of the discharge pipe facing the injection port of the upper mold; a turntable rotating on the top of the hot melt tank, wherein circumferentially distributed vertical rods are mounted on the turntable, and triangular blocks are fixedly connected to the outer wall of the vertical rods, the inclined surfaces of the triangular blocks facing downwards, and a drive unit for driving the turntable to rotate is provided on the frame.

[0013] To facilitate efficient heating of scrap aluminum, preferably, the drive unit includes a bracket fixedly connected to the hot melt tank, on which a drive motor is fixedly mounted. A drive shaft is fixedly connected to the turntable, and the drive shaft is connected to the output shaft of the drive motor through two meshing transmission gears.

[0014] To enable the vertical rod to rotate, a ring gear is fixedly installed on the bracket, and a driven gear is fixedly installed on the vertical rod. A lifting part is connected between the driven gear and the ring gear, and the lifting part is used to drive the driven gear to rise, fall, and rotate.

[0015] To enable the vertical rod to drive the triangular block to move up and down reciprocally, the lifting part further includes a reciprocating screw rotatably connected to the turntable, an inertial gear fixedly installed on the reciprocating screw, wherein the inertial gear meshes with the driven gear and the ring gear, a lifting plate is threadedly connected to the outer wall of the reciprocating screw, and the upper end of the vertical rod is rotatably connected to the lifting plate.

[0016] To facilitate the loading of the hot melt tank, a feeding hopper is fixedly installed on the frame, and a flat material tube facing the feeding port is fixedly provided at the lower end of the feeding hopper. A thin plate is longitudinally slidably installed inside the flat material tube, and a dredging part is provided on the turntable to drive the thin plate to move up and down.

[0017] To further prevent blockage of the flat material tube, the unblocking part includes a fixing plate fixedly connected to the outer wall of the flat material tube, and a T-shaped plate fixedly connected to the lower end of the thin plate. A spring is installed between the T-shaped plate and the fixing plate. When the lifting plate rotates with the turntable, multiple lifting plates will sequentially lift the T-shaped plate.

[0018] To facilitate heat dissipation of the lower and upper molds, a first heat pipe and a second heat pipe are fixedly installed inside the lower and upper molds, respectively, and a third heat pipe is fixedly installed inside the thin plate. The first, second, and third heat pipes are connected in series via a first long pipe, a second long pipe, and a third long pipe, respectively. A rotating tube is rotatably connected to the third long pipe, and a first fan blade is fixedly installed inside the rotating tube. The hot melt tank is provided with a circulation part that drives the rotating tube to rotate.

[0019] To enable the coolant to circulate automatically, the circulation unit further includes a vertical pipe rotatably connected to the outer wall of the hot melt tank. A second fan blade is fixedly installed on the inner wall of the vertical pipe. The vertical pipe and the rotating pipe are connected by a chain drive. An air blowing pipe is fixedly connected to the upper end of the vertical pipe. The hot melt tank is provided with an air supply unit for blowing air onto the air blowing pipe.

[0020] To further utilize the waste gas effectively, the gas supply unit includes a gas storage tank fixedly installed on the hot melt tank. The input end of the gas storage tank is fixedly connected to an inflation pipe extending into the hot melt tank. The output end of the gas storage tank is fixedly connected to an air blowing pipe through a delivery pipe. Both the inflation pipe and the delivery pipe are fixedly installed with a one-way valve, and a valve is installed in the delivery pipe.

[0021] Compared with the prior art, the present invention provides an aluminum profile manufacturing apparatus, which has the following beneficial effects:

[0022] 1. This aluminum profile manufacturing device uses a drive motor to rotate a turntable, which in turn drives a vertical rod and a triangular block to stir the scrap aluminum material in a hot melt tank. This allows the scrap aluminum material to be heated more thoroughly and facilitates the removal of impurities from the scrap aluminum material, thereby indirectly improving the quality of the subsequent aluminum profiles.

[0023] 2. In this aluminum profile manufacturing device, as the turntable rotates, the lifting plate will drive the triangular block to move up and down inside the hot melt tank. The reciprocating triangular block can lift the scrap aluminum material at the bottom of the hot melt tank upwards, thereby improving the heating uniformity and hot melt efficiency of the scrap aluminum material.

[0024] 3. The aluminum profile manufacturing device drives the driven gear to rotate through the inertial gear, thereby causing the triangular block to move up and down in different orientations in the hot melt tank, so that the triangular block can better break up the scrap aluminum material, thereby making the scrap aluminum material heat up more efficiently and removing impurities.

[0025] 4. In this aluminum profile manufacturing device, by opening the valve in the delivery pipe, the coolant in the first, second, and third heat pipes will circulate. When the coolant passes through the third heat pipe, the third heat pipe will transfer heat to the scrap aluminum material in the flat material tube through the thin plate. The scrap aluminum material will be heated, while the coolant can dissipate heat. This effectively utilizes the temperature of the upper and lower molds and reduces heat waste. Due to the high thermal conductivity of aluminum, the heat dissipation efficiency of the lower and upper molds can be effectively guaranteed.

[0026] 5. This aluminum profile manufacturing device, by opening the valves in the flat material pipe and the feeding port, allows the waste aluminum material in the feeding hopper to be continuously discharged into the feeding port. The flowing waste aluminum material can significantly improve the heat dissipation efficiency of the third heat pipe, thereby improving the heat dissipation efficiency of the upper and lower molds. At the same time, it also completes the automatic replenishment of the hot melt tank. Since the waste aluminum material is preheated, the heating power of the hot melt tank can be reduced, making it more environmentally friendly.

[0027] 6. The aluminum profile manufacturing device drives the lifting plate to revolve around its axis via a turntable. As multiple lifting plates pass the lower end of the T-shaped plate in sequence, the T-shaped plate will shake up and down, thereby causing the thin plate to shake up and down inside the flat tube. This can prevent blockage in the flat tube and improve the heat conduction efficiency of the flat tube. Attached Figure Description

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0038] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Example 1

[0039] Reference Figures 1-8 An aluminum profile manufacturing process includes the following steps:

[0040] Step 1: Crush the recycled aluminum metal;

[0041] Step 2: Melt the crushed aluminum metal.

[0042] Step 3: Allow most of the impurities in the molten metal to float to the surface of the solution;

[0043] Step 4: Pour molten aluminum into a mold for shaping;

[0044] Step 5: Cool the mold using crushed aluminum metal. Example 2

[0045] Reference Figures 1-8An aluminum profile manufacturing apparatus includes a frame 1 for supporting the entire apparatus, and further includes: a hot melt tank 2 with a feeding port 4 and a discharge pipe 3, fixedly installed on the frame 1, with valves installed in both the feeding port 4 and the discharge pipe 3. The hot melt tank 2 is used to heat and melt scrap aluminum. A lower mold 5 is fixedly installed on the frame 1, and an upper mold 7 is installed on the lower mold 5 via a lifting device 6. The lifting device 6 is a telescopic cylinder used to drive the upper mold 7 to open and close. The output end of the discharge pipe 3 faces the injection port of the upper mold 7. A turntable 8 rotates on the top of the hot melt tank 2. The turntable 8 is equipped with circumferentially distributed vertical rods 11, the number of which is 2 to 6, preferably 4 in this application. Triangular blocks 12 are fixedly connected to the outer wall of the vertical rods 11. The triangular blocks 12 are right-angled triangles with the inclined surface facing down and one right-angled side facing up. The frame 1 is provided with a drive unit for driving the turntable 8 to rotate.

[0046] Specifically, during use, the crushed scrap aluminum is added into the hot melt tank 2 through the feeding port 4. The scrap aluminum is then heated in the hot melt tank 2 to melt it. During this process, the drive unit drives the turntable 8 to rotate, which in turn drives the vertical rod 11 and the triangular block 12 to stir the scrap aluminum in the hot melt tank 2. This ensures that the scrap aluminum is heated more thoroughly and facilitates the removal of impurities from the scrap aluminum, indirectly improving the quality of the subsequent aluminum profiles. When it is necessary to inject the molten aluminum into the lower mold 5 and the upper mold 7, the valve in the discharge pipe 3 is opened, and the molten aluminum enters the lower mold 5 and the upper mold 7 from the injection port of the upper mold 7. After the injection is completed, the lower mold 5 and the upper mold 7 are cooled. Finally, the lifting device 6 moves the upper mold 7 away from the lower mold 5, and the shaped aluminum profile is removed. Example 3

[0047] Reference Figures 1-3 as well as Figure 6 Similar to Embodiment 2, but further, a specific implementation scheme for the drive unit is disclosed.

[0048] The aforementioned drive unit includes a bracket 9 fixedly connected to the hot melt tank 2, and a drive motor 13 fixedly mounted on the bracket 9. A drive shaft 10 is fixedly connected to the turntable 8, and the drive shaft 10 is connected to the output shaft of the drive motor 13 through two meshing transmission gears 14.

[0049] Specifically, during the melting of scrap aluminum using the hot melt tank 2, the drive motor 13 is started. The drive motor 13 drives the drive shaft 10 to rotate through two meshing transmission gears 14. The drive shaft 10 then drives the turntable 8 to rotate. The turntable 8 drives the vertical rod 11 and the triangular block 12 to stir the scrap aluminum in the hot melt tank 2, so that the scrap aluminum is heated more thoroughly and the impurities in the scrap aluminum are removed, which indirectly improves the quality of the subsequent aluminum profiles.

[0050] A ring gear 17 is fixedly installed on the bracket 9, and a driven gear 16 is fixedly installed on the vertical rod 11. A lifting part is connected between the driven gear 16 and the ring gear 17. The lifting part is used to drive the driven gear 16 to rise and rotate. The lifting part includes a reciprocating screw 15 rotatably connected to the turntable 8. An idler gear is fixedly installed on the reciprocating screw 15. The idler gear is not labeled in the figure. The idler gear meshes with the driven gear 16 and the ring gear 17. A lifting plate 18 is threadedly connected to the outer wall of the reciprocating screw 15. The upper end of the vertical rod 11 is rotatably connected to the lifting plate 18.

[0051] Specifically, during the rotation of turntable 8, vertical rod 11 revolves around the axis of turntable 8, driving driven gear 16 and idler gear to revolve synchronously. The idler gear, under the action of ring gear 17, drives reciprocating screw 15 to rotate. Reciprocating screw 15 then drives vertical rod 11 to move up and down through lifting plate 18. Lifting plate 18 then drives triangular block 12 to move up and down inside hot melt tank 2. When triangular block 12 is lifted upwards, its inclined surface faces downwards, so its right-angled side can lift the scrap aluminum material at the bottom of hot melt tank 2 upwards. When triangular block 12 moves downwards, it will be inserted into the bottom of hot melt tank 2 under the guidance of its inclined surface. Thus, the up-and-down reciprocating triangular block 12 can lift the scrap aluminum material at the bottom of hot melt tank 2 upwards, thereby improving the heating uniformity and hot melt efficiency of scrap aluminum material.

[0052] Specifically, during the rotation of the reciprocating screw 15, the reciprocating screw 15 will also drive the driven gear 16 to rotate through the inertial gear. The driven gear 16 will drive the vertical rod 11 to rotate, and the vertical rod 11 will drive the triangular block 12 to revolve around the vertical rod 11. This will cause the triangular block 12 to move up and down in different orientations in the hot melt tank 2, so that the triangular block 12 can better break up the scrap aluminum material, thereby enabling the scrap aluminum material to be heated more efficiently and impurities to be removed. Example 4

[0053] Reference Figures 1-4 as well as Figure 7 Similar to Example 3, but further, a specific implementation scheme is disclosed to facilitate the loading of materials into the hot melt tank 2.

[0054] A feeding hopper 19 is fixedly installed on the frame 1. A flat material tube 20 facing the feeding port 4 is fixedly provided at the lower end of the feeding hopper 19. A valve is installed inside the flat material tube 20. A thin plate 21 is slidably installed in the flat material tube 20. A clearing part is provided on the turntable 8 to drive the thin plate 21 to move up and down. The clearing part includes a fixing plate 23 fixedly connected to the outer wall of the flat material tube 20. A T-shaped plate 22 is fixedly connected to the lower end of the thin plate 21. A spring 24 is installed between the T-shaped plate 22 and the fixing plate 23. When the lifting plate 18 rotates with the turntable 8, multiple lifting plates 18 will lift the T-shaped plate 22 in sequence.

[0055] Specifically, during use, the crushed scrap aluminum is placed into the feeding hopper 19, and then the valves in the flat material tube 20 and the feeding port 4 are opened, allowing the scrap aluminum in the feeding hopper 19 to enter the hot melt tank 2 through the flat material tube 20 and the feeding port 4, thus facilitating the feeding process. During the rotation of the turntable 8, the turntable 8 will drive the lifting plate 18 to revolve around its axis. When the lifting plate 18 moves to the bottom of the T-shaped plate 22, the lifting plate 18 will lift the T-shaped plate 22 upward. When the lifting plate 18 moves away from the bottom of the T-shaped plate 22, the spring 24 will drive the T-shaped plate 22 to slide downward and reset. Thus, when multiple lifting plates 18 pass the lower end of the T-shaped plate 22 in sequence, the T-shaped plate 22 will shake up and down, thereby causing the thin plate 21 to shake up and down in the flat material tube 20, which can prevent blockage in the flat material tube 20. Example 5

[0056] Reference Figures 1-5 as well as Figure 8 Similar to Embodiment 4, but further, a specific implementation scheme for heat dissipation between the lower mold 5 and the upper mold 7 is disclosed.

[0057] The lower mold 5 and the upper mold 7 are respectively fixedly installed with a first heat pipe 25 and a second heat pipe 27, and a third heat pipe 28 is fixedly installed in the thin plate 21. The first heat pipe 25, the second heat pipe 27 and the third heat pipe 28 are connected in series through a first long pipe 26, a second long pipe 29 and a third long pipe 30, forming a closed loop filled with coolant. A rotating pipe 31 is rotatably connected to the third long pipe 30. A first fan blade is fixedly installed in the rotating pipe 31. The first fan blade is not shown in the figure. Its function is to replace the circulating pump. The hot melt tank 2 is provided with a circulation part to drive the rotating pipe 31 to rotate.

[0058] Specifically, when cooling of the lower mold 5 and upper mold 7 is required, the rotating tube 31 is driven to rotate by the circulation section. The rotating tube 31 then drives the first fan blade inside to rotate. The rotating first fan blade causes the coolant in the third long tube 30 to flow continuously. Under the action of the first long tube 26 and the second long tube 29, the coolant in the first heat pipe 25, the second heat pipe 27 and the third heat pipe 28 will circulate. When the coolant enters the first heat pipe 25 and the second heat pipe 27, the coolant will absorb the temperature of the lower mold 5 and the upper mold 7, thereby completing the cooling work of the upper mold 7 and the lower mold 5. When the coolant passes through the third heat pipe 28, the third heat pipe 28 will transfer heat to the scrap aluminum in the flat material tube 20 through the thin plate 21. The scrap aluminum will be heated, while the coolant can dissipate heat. The temperature of the upper mold 7 and the lower mold 5 is effectively utilized, and heat waste is reduced. Since aluminum has high thermal conductivity, the heat dissipation efficiency of the lower mold 5 and the upper mold 7 can be effectively guaranteed.

[0059] The aforementioned circulation unit includes a vertical pipe 32 rotatably connected to the outer wall of the hot melt tank 2. A second fan blade is fixedly installed on the inner wall of the vertical pipe 32, which is not shown in the figure. The vertical pipe 32 and the rotating pipe 31 are connected by a chain drive 33. An air blowing pipe 34 is fixedly connected to the upper end of the vertical pipe 32. The hot melt tank 2 is provided with an air supply unit for blowing air onto the air blowing pipe 34. The air supply unit includes an air storage tank 35 fixedly installed on the hot melt tank 2. The air storage tank 35 is used to store high-pressure gas. An inflation pipe 36 extending into the hot melt tank 2 is fixedly connected to the input end of the air storage tank 35. The output end of the air storage tank 35 is fixedly connected to the air blowing pipe 34 through a delivery pipe 37. A one-way valve is fixedly installed in both the inflation pipe 36 and the delivery pipe 37, and a valve is installed in the delivery pipe 37.

[0060] Specifically, during the heating process of the hot melt tank 2, the valve in the loading port 4 is closed. Since the scrap aluminum contains impurities, the heated scrap aluminum will generate waste gas. The waste gas will be transported to the storage tank 35 through the air filling pipe 36. When the lower mold 5 and the upper mold 7 need to be cooled, the valve in the conveying pipe 37 is opened, so that the gas stored in the storage tank 35 is transported to the blowing pipe 34 through the conveying pipe 37. The blowing pipe 34 will blow air onto the vertical pipe 32. Since the vertical pipe 32 is equipped with a second fan blade, the vertical pipe 32 will drive the rotating pipe 31 to rotate through the chain drive 33. The rotating pipe 31 will drive the first fan blade inside it to rotate. The rotating first fan blade will cause the coolant in the third long pipe 30 to flow continuously, so as to complete the heat dissipation of the mold.

[0061] In use, the crushed scrap aluminum is placed into the feeding hopper 19, and then the valves in the flat material pipe 20 and the feeding port 4 are opened, allowing the scrap aluminum in the feeding hopper 19 to enter the hot melt tank 2 through the flat material pipe 20 and the feeding port 4. The scrap aluminum is then heated in the hot melt tank 2 to melt it. During this process, the drive motor 13 is started, and the drive motor 13 drives the drive shaft 10 to rotate through two meshing transmission gears 14. The drive shaft 10 then drives the turntable 8 to rotate, and the turntable 8 drives the vertical rod 11 and the triangular block 12 to stir the scrap aluminum in the hot melt tank 2, so that the scrap aluminum is heated more thoroughly and the impurities in the scrap aluminum are removed, which indirectly improves the quality of the subsequent aluminum profiles.

[0062] During the rotation of turntable 8, vertical rod 11 revolves around the axis of turntable 8, driving driven gear 16 and idler gear to revolve synchronously. The idler gear, under the action of ring gear 17, drives reciprocating screw 15 to rotate. Reciprocating screw 15 then drives vertical rod 11 to move up and down through lifting plate 18. Lifting plate 18 drives triangular block 12 to move up and down inside hot melt tank 2. When triangular block 12 is lifted upward, its inclined surface faces downward, so its right-angled side can lift the scrap aluminum material at the bottom of hot melt tank 2 upward. When triangular block 12 moves downward, it will be inserted into the bottom of hot melt tank 2 under the guidance of its inclined surface. Thus, the up-and-down reciprocating triangular block 12 can lift the scrap aluminum material at the bottom of hot melt tank 2 upward, thereby improving the heating uniformity and hot melt efficiency of scrap aluminum material.

[0063] During the rotation of the reciprocating screw 15, the reciprocating screw 15 will also drive the driven gear 16 to rotate through the inertial gear. The driven gear 16 will drive the vertical rod 11 to rotate, and the vertical rod 11 will drive the triangular block 12 to revolve around the vertical rod 11. This will cause the triangular block 12 to move up and down in different directions in the hot melt tank 2, so that the triangular block 12 can better break up the scrap aluminum, thereby enabling the scrap aluminum to be heated more efficiently and impurities to be removed.

[0064] After the scrap aluminum is melted, the valve in the discharge pipe 3 is opened, and the molten aluminum flows from the upper mold 7 into the lower mold 5. After the molten aluminum cools and solidifies, the lifting device 6 lifts the upper mold 7 upwards, away from the lower mold 5, and the cooled and shaped aluminum profile is then removed from the lower mold 5.

[0065] During the heating process of the hot melt tank 2, the valve in the loading port 4 is closed. Due to the impurities in the scrap aluminum, the heated scrap aluminum will generate waste gas. The waste gas will be transported to the storage tank 35 through the air filling pipe 36. When the lower mold 5 and upper mold 7 need to be cooled, the valve in the conveying pipe 37 is opened, so that the gas stored in the storage tank 35 is transported to the blowing pipe 34 through the conveying pipe 37. The blowing pipe 34 will blow air into the vertical pipe 32. Since the second fan blade is installed in the vertical pipe 32, the vertical pipe 32 will drive the rotating pipe 31 to rotate through the chain drive 33. The rotating pipe 31 will drive the first fan blade inside it to rotate. The rotating first fan blade will cause the coolant in the third long pipe 30 to flow continuously and in the first long pipe. Under the action of 26 and the second long pipe 29, the coolant in the first heat pipe 25, the second heat pipe 27 and the third heat pipe 28 will circulate. When the coolant enters the first heat pipe 25 and the second heat pipe 27, the coolant will absorb the temperature of the lower mold 5 and the upper mold 7, thereby completing the cooling work of the upper mold 7 and the lower mold 5. When the coolant passes through the third heat pipe 28, the third heat pipe 28 will transfer the heat to the scrap aluminum in the flat material tube 20 through the thin plate 21. The scrap aluminum will be heated, while the coolant can dissipate heat. The temperature of the upper mold 7 and the lower mold 5 is effectively utilized, and the waste of heat is reduced. Since aluminum has high thermal conductivity, the heat dissipation efficiency of the lower mold 5 and the upper mold 7 can be effectively guaranteed.

[0066] During the heat dissipation process of the lower mold 5 and the upper mold 7, in order to improve the heat dissipation efficiency, the valves in the flat material pipe 20 and the feeding port 4 are opened, so that the waste aluminum material in the feeding hopper 19 is continuously discharged into the feeding port 4. The flowing waste aluminum material can significantly improve the heat dissipation efficiency of the third heat pipe 28, thereby improving the heat dissipation efficiency of the upper mold 7 and the lower mold 5. At the same time, the automatic material replenishment of the hot melt tank 2 is also completed. Since the waste aluminum material is preheated, the heating power of the hot melt tank 2 can be reduced, making it more environmentally friendly.

[0067] During the rotation of turntable 8, turntable 8 will drive lifting plate 18 to revolve around its axis. When lifting plate 18 moves to the bottom of T-shaped plate 22, lifting plate 18 will push T-shaped plate 22 upward. When lifting plate 18 moves away from the bottom of T-shaped plate 22, spring 24 will drive T-shaped plate 22 to slide downward and reset. Thus, when multiple lifting plates 18 pass the lower end of T-shaped plate 22 in sequence, T-shaped plate 22 will shake up and down, thereby driving thin plate 21 to shake up and down in flat tube 20. On the one hand, this can prevent blockage in flat tube 20, and on the other hand, it can improve the heat conduction efficiency of flat tube 20.

[0068] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
