Description

Technical Field

[0001] This application relates to the field of oil cooler technology, and in particular to a heat exchange tube type oil cooler. Background Technology

[0002] Heat exchange tubular oil coolers are key components for ensuring stable equipment operation. Their core function is to cool the high-temperature oil generated during equipment operation to a safe operating temperature through heat exchange between the coolant and the oil, thereby preventing equipment wear, efficiency loss, or even shutdown due to excessively high oil temperature. As industrial equipment develops towards higher power and higher load, the heating rate of oil has significantly increased, placing more stringent requirements on the heat exchange efficiency and cooling uniformity of oil coolers.

[0003] Traditional heat exchange tubular oil coolers typically employ a fixed condenser tube structure, creating a relatively static heat exchange environment once the chamber is filled with coolant. However, due to the slow natural convection velocity of the coolant within the chamber, the high-temperature coolant that has completed heat exchange with the condenser tubes cannot diffuse quickly. This results in localized high temperatures around the condenser tubes, while areas further away remain at lower temperatures. This uneven temperature distribution leads to significant differences in heat exchange efficiency across different sections of the condenser tubes, resulting in poor cooling performance and large fluctuations in the oil outlet temperature. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a heat exchange tube-type oil cooler.

The bottom of the other connecting plate 1 passes through the opening 2 and is hinged to one side of the other mounting block.

[0007] Preferably, oil storage tanks are fixedly installed on both sides of the inner circumference of the cylinder. An installation opening is provided on the side of each of the two oil storage tanks that are close to each other. A rotating tube plate is rotatably installed on the inner circumference of each of the two installation openings. The center positions of the sides of the two rotating tube plates that are close to each other are fixedly connected to both sides of several condenser tubes.

[0011] Preferably, the cavity is sealed and filled with coolant, with the inlet pipe and outlet pipe located between the two support plates.

[0012] Preferably, stirring plates are fixedly installed at equal intervals on the edges of the two support plates that are close to each other, and the stirring plates are arranged in a spiral shape.

[0013] Compared with the prior art, the beneficial effects of this application are as follows: (1) This invention proposes a heat exchange tubular oil cooler, which is provided with a cylinder, end cap, oil inlet assembly, oil outlet assembly, condenser tube, support plate, mounting bracket, electric telescopic rod, mounting block, connecting plate 1, water inlet pipe 1, water outlet pipe 1, check valve and linkage assembly. After the water inlet pipe 1 fills the cavity between the two support plates with coolant, the high temperature oil enters the condenser tube through the oil inlet assembly and exchanges heat with the coolant to cool down. As the coolant temperature is uneven, the inverted electric telescopic rod shortens, and its bottom will pull the corresponding end of the connecting plate 1 upward. Since the other end of the connecting plate 1 is hinged to the mounting block, this pulling causes the connecting plate 1 to rotate around The hinge point of the mounting block rotates, which in turn drives the mounting block and the support plate fixed to it to rotate. The support plate then drives the condenser tube to rotate synchronously. At the same time, the one-way valve in the inlet pipe moves through the linkage assembly, introducing new coolant. Another electric telescopic rod shortens, which also drives the support plate and condenser tube to rotate in the same direction through the connecting plate and the mounting block. At the same time, the one-way valve in the outlet pipe moves through another set of linkage assemblies, discharging the old coolant. The condenser tube continues to rotate and stir the coolant, making it evenly mixed and fully contacting the condenser tube. This achieves enhanced heat exchange through the rotation of the condenser tube, while dynamically replacing the coolant, improving the heat exchange effect and cooling uniformity.

[0014] (2) The present invention proposes a heat exchange tubular oil cooler, which is equipped with an oil storage tank, a rotating tube plate, an oil inlet pipe and an oil outlet pipe. High-temperature oil enters the oil storage tank through the oil inlet pipe and then enters the condenser tube. When the oil storage tank is not full, only the condenser tube with a lower vertical height enters the oil. The electric telescopic rod drives the support plate, the rotating tube plate and the condenser tube to rotate, so that the position of the condenser tube changes continuously and the contact position with the oil is adjusted to ensure that the oil enters all the condenser tubes evenly. Afterwards, the oil is discharged from the oil outlet pipe through another oil storage tank. This realizes that the rotation of the rotating tube plate and the condenser tube can ensure that the oil enters all the condenser tubes evenly when the oil storage tank is not full, thus ensuring sufficient heat exchange.

[0026] One preferred embodiment of this application, such as Figures 1 to 7As shown, a heat exchange tubular oil cooler includes: a cylindrical body 1, with end caps 9 fixedly installed on both sides of the cylindrical body 1; and further includes: an oil inlet assembly, an oil outlet assembly, condenser pipes 10, a support plate 11, a transmission assembly, a water inlet pipe 16, a water outlet pipe 17, a one-way valve 18, and a linkage assembly; the oil inlet assembly is located on one side of the inner circumference of the cylindrical body 1 for high-temperature oil to enter the cylindrical body 1 through the oil inlet assembly; the oil outlet assembly is located on the other side of the inner circumference of the cylindrical body 1 for high-temperature oil to exit the cylindrical body 1 through the oil outlet assembly; there are several condenser pipes 10, which are evenly arranged and fixedly installed on... Between the oil inlet assembly and the oil outlet assembly; there are two support plates 11, each sleeved on both sides of the outer circumference of several condenser tubes 10, forming a cavity between the two support plates 11; there are two sets of transmission assemblies, each set located on both sides of the cylinder 1, for driving the support plates 11 and condenser tubes 10 to rotate; the water inlet pipe 16 is vertically and fixedly installed on one side of the outer circumference of the cylinder 1; the water outlet pipe 17 is vertically and fixedly installed on the other side of the outer circumference of the cylinder 1; there are two one-way valves 18, each located inside the water inlet pipe 16 and the water outlet pipe 17, respectively. Valve 18 allows for consistent flow direction; there are two sets of linkage components, which are respectively located between the two one-way valves 18 and the inlet pipe 16 and the outlet pipe 17, so that the movement of the two sets of transmission components can drive the corresponding two one-way valves 18 to move up and down through the two sets of linkage components; the transmission components include: mounting bracket 12, electric telescopic rod 13, mounting block 14 and connecting plate 15, the two mounting brackets 12 are respectively fixedly installed on both sides of the outer circumference of the cylinder 1, and the two electric telescopic rods 13 are respectively fixedly installed on the top inner wall of one mounting bracket 12 and the bottom inner wall of the other mounting bracket 12. Mounting blocks 14 are fixedly installed on the edges of the two support plates 11 on opposite sides. Openings 2 are provided on both sides of the inner wall of the cylinder 1. The two openings 2 are respectively set to correspond to the two electric telescopic rods 13. The bottom of one connecting plate 15 is hinged to the top of the electric telescopic rod 13 near the oil outlet assembly. The top of the other connecting plate 15 is hinged to the bottom of the other electric telescopic rod 13. The top of one connecting plate 15 passes through the opening 2 and is hinged to one side of one mounting block 14. The bottom of the other connecting plate 15 passes through the opening 2 and is hinged to one side of the other mounting block 14.

[0027] First, coolant is injected into the cavity between the two support plates 11 through the inlet pipe 16 until the cavity is full. Then, high-temperature oil is introduced into the condenser tube 10 through the oil inlet assembly. During the flow of the high-temperature oil in the condenser tube 10, it exchanges heat with the coolant in the cavity to achieve cooling. As heat exchange proceeds, the temperature of the coolant in the cavity gradually increases and becomes unevenly distributed. At this time, the electric telescopic rod 13 is activated. One of the electric telescopic rods 13 installed on the inner wall of the top of the mounting bracket 12 is in an inverted state. This electric telescopic rod 13 shortens, and its bottom drives the top of the corresponding connecting plate 15 to move upward. Through the mounting block 14, it drives the support plate 11 to rotate, which in turn drives the condenser tube 10 to rotate synchronously. At the same time, the electric telescopic rod 13 drives the one-way valve 18 in the inlet pipe 16 to move through the linkage assembly, so that new coolant enters the cavity through the inlet pipe 16 and the one-way valve 18. The other electric telescopic rod 13 installed on the inner wall of the bottom of the mounting bracket 12 is activated. 3. The top of the tube is shortened, and the corresponding connecting plate 15 drives the mounting block 14 on the other side, which in turn drives the support plate 11 and the condenser tube 10 to rotate. The two support plates 11 rotate in the same direction. At the same time, the linkage component drives the one-way valve 18 in the outlet pipe 17 to move, and discharges the old coolant in the cavity through the outlet pipe 17 and the one-way valve 18. During the whole process, the condenser tube 10 rotates continuously, constantly stirring the coolant in the cavity, so that the newly injected low-temperature coolant and the original heated coolant are quickly and evenly mixed, avoiding the formation of areas with excessively high local temperatures. At the same time, the evenly mixed coolant can make more full contact with the outer circumference of the condenser tube 10, increasing the heat exchange area and contact efficiency. With the up and down movement of the one-way valve 18, the coolant is dynamically replaced, thereby more efficiently removing the heat of the high-temperature oil in the condenser tube 10. This achieves enhanced heat exchange through the rotation of the condenser tube, while dynamically replacing the coolant, improving the heat exchange effect and cooling uniformity.

[0028] Further reference Figure 3 and Figure 4 Oil storage tanks 201 are fixedly installed on both sides of the inner circumference of the cylinder 1. An installation opening 1 is opened on the side of the two oil storage tanks 201 that are close to each other. A rotating tube plate 202 is rotatably installed on the inner circumference of the two installation openings 1. The center position of the side of the two rotating tube plates 202 that are close to each other is fixedly connected to both sides of several condenser tubes 10. The oil inlet assembly includes: an oil inlet pipe 203. One side of the oil inlet pipe 203 is fixedly installed on the outer wall of one side of one oil storage tank 201, and the other side of the oil inlet pipe 203 passes through one side of one end cap 9. The oil outlet assembly includes: an oil outlet pipe 204. One side of the oil outlet pipe 204 is fixedly installed on the outer wall of one side of another oil storage tank 201, and the other side of the oil outlet pipe 204 passes through one side of another end cap 9.

[0029] High-temperature oil enters one of the oil storage tanks 201 through the oil inlet pipe 203. Since the condenser tubes 10 are evenly arranged and fixedly installed between the two rotating tube plates 202, the oil in the oil storage tank 201 can enter the condenser tubes 10. When the oil storage tank 201 is not full, the oil can only enter the condenser tube 10 with the lower vertical height. When the electric telescopic rod 13 is activated, it drives the support plate 11 to rotate, thereby driving the rotating tube plate 202 and the condenser tubes 10 to rotate together. During the rotation, the position of the condenser tubes 10 changes continuously, constantly adjusting the contact position with the oil in the oil storage tank 201 to ensure that the oil enters all the condenser tubes 10 evenly. Then the oil flows in the condenser tubes 10 and finally enters the other oil storage tank 201, and is discharged through the oil outlet pipe 204, completing the heat exchange operation. This achieves that even if the oil storage tank is not full, the rotation of the rotating tube plate and the condenser tubes can ensure that the oil enters all the condenser tubes evenly, ensuring that the heat exchange is fully carried out.

[0030] Further reference Figure 1 , Figures 3-6 The linkage components include: a second water inlet pipe 301, a second water outlet pipe 302, and two second connecting plates 303. The second water inlet pipe 301 is vertically inserted into the first water inlet pipe 16. One of the one-way valves 18 is horizontally fixedly installed at the bottom of the inner circumference of the second water inlet pipe 301. The second water outlet pipe 302 is vertically inserted into the first water outlet pipe 17. The other one-way valve 18 is horizontally fixedly installed at the top of the inner circumference of the second water outlet pipe 302. The two second connecting plates 303 are horizontally fixedly installed between the telescopic ends of the two electric telescopic rods 13 and the outer circumference of the second water inlet pipe 301 and the outer circumference of the second water outlet pipe 302, respectively.

[0031] When the electric telescopic rod 13 extends or retracts, the connecting plate 2 303 drives the water inlet pipe 2 301 to move vertically within the water inlet pipe 1 16. The one-way valve 18 installed at the bottom of the inner circumference of the water inlet pipe 2 301 moves accordingly, opening and closing the passage between the water inlet pipe 1 16 and the water inlet pipe 2 301, controlling the entry of coolant. At the same time, in another set of linkage components, the electric telescopic rod 13 drives the water outlet pipe 2 302 to move vertically within the water outlet pipe 1 17 via the connecting plate 2 303. The one-way valve 18 installed at the top of the inner circumference of the water outlet pipe 2 302 moves synchronously, opening and closing the passage between the water outlet pipe 1 17 and the water outlet pipe 2 302, controlling the discharge of coolant. The movement directions of the two one-way valves 18 are coordinated to ensure that the coolant flows in the set direction.

[0032] Further reference Figure 7Leak-proof pads 401 are fixedly installed on the top of the inner wall of the inlet pipe 16 and the bottom of the inner wall of the outlet pipe 17. The inner walls of the two leak-proof pads 401 are respectively fitted to the top of the outer wall of the inlet pipe 301 and the bottom of the outer wall of the outlet pipe 302. Leak-proof pads 402 are fixedly installed on the bottom of the outer wall of the inlet pipe 301 and the top of the outer wall of the outlet pipe 302. The outer walls of the two leak-proof pads 402 are respectively fitted to the bottom of the inner wall of the inlet pipe 16 and the top of the inner wall of the outlet pipe 17.

[0033] When inlet pipe 2 301 moves vertically within inlet pipe 1 16, the leak-proof gasket 401 on the top of the inner circumference of inlet pipe 1 16 remains in contact with the top of the outer circumference of inlet pipe 2 301, while the leak-proof gasket 402 on the bottom of the outer circumference of inlet pipe 2 301 remains in contact with the bottom of the inner circumference of inlet pipe 16. This cooperation prevents coolant leakage at the gap between inlet pipe 1 16 and inlet pipe 2 301. Simultaneously, outlet pipe 2 30... 2. The device moves vertically within the outlet pipe 17. The leak-proof pad 401 at the bottom of the inner circumference of the outlet pipe 17 is always in contact with the bottom of the outer circumference of the outlet pipe 302, and the leak-proof pad 402 at the top of the outer circumference of the outlet pipe 302 is always in contact with the top of the inner circumference of the outlet pipe 17. Through the combined action of these two sets of leak-proof pads, the coolant is prevented from leaking at the gap between the outlet pipe 17 and the outlet pipe 302, ensuring reliable sealing of the coolant during flow.

[0034] Further reference Figure 3 and Figure 4 Two support plates 11 are rotatably installed on both sides of the inner circumference of the cylinder 1. A sealing gasket 501 is fixedly installed on the side of the two support plates 11 that are close to each other. The outer circumference of the sealing gasket 501 is fitted to the inner circumference of the cylinder 1. The cavity is sealed and filled with coolant. The inlet pipe 16 and the outlet pipe 17 are located between the two support plates 11.

[0035] Driven by the electric telescopic rod 13 through the connecting plate 15 and the mounting block 14, the two support plates 11 rotate along the inner circumference of the cylinder 1. During this process, the outer circumference of the sealing gasket 501 on one side of the two support plates 11 remains tightly fitted with the inner circumference of the cylinder 1. Even if the support plates 11 continue to rotate, the sealing gasket 501 can effectively prevent coolant from leaking from the gap between the support plates 11 and the cylinder 1, ensuring the sealing of the cavity between the two support plates 11 and ensuring that the coolant always exchanges heat with the condenser pipe 10 within the cavity. When the electric telescopic rod 13 drives the support plate 11 and the condenser pipe 10 to rotate, the sealed cavity ensures that the coolant will not leak out and can fully contact the rotating condenser pipe 10 for heat exchange within the cavity. At the same time, the inlet pipe 16 located between the two support plates 11 injects new coolant into the cavity, while the outlet pipe 17 discharges the old coolant that has completed heat exchange within the cavity. Through the cooperation of the inlet pipe 16 and the outlet pipe 17, the coolant is dynamically circulated, maintaining the cooling effect of the coolant within the cavity and ensuring that heat exchange continues to be carried out efficiently.

[0036] Further reference Figure 3 Two support plates 11 are fixedly installed with stirring plates 701 at equal intervals on the edges of their adjacent sides. The stirring plates 701 are arranged in a spiral shape.

[0037] When the electric telescopic rod 13 drives the two support plates 11 to rotate, the spiral stirring plates 701 located close to one side edge of the support plates 11 rotate together. Since the stirring plates 701 are equidistantly arranged and spiral in shape, they will generate a spiral thrust on the coolant in the cavity during rotation, causing the coolant to flow along the spiral path. This not only accelerates the mixing of the newly injected coolant with the original coolant in the cavity, but also enhances the turbulence of the coolant, allowing the coolant to contact the condenser tube 10 more fully, and further improving the heat exchange efficiency.

[0038] Working principle: First, coolant is injected into the cavity between the two support plates 11 through the inlet pipe 16 until the cavity is full. Then, high-temperature oil enters one of the oil storage tanks 201 through the oil inlet pipe 203. Since the condenser tubes 10 are evenly arranged and fixedly installed between the two rotating tube plates 202, the oil in the oil storage tank 201 can enter the condenser tubes 10. During the flow of the high-temperature oil in the condenser tubes 10, heat exchange occurs with the coolant in the cavity, achieving cooling. As heat exchange proceeds, the temperature of the coolant in the cavity gradually increases and becomes unevenly distributed. At this time, the electric telescopic rod 13 is activated. One of the electric telescopic rods 13 installed on the inner wall of the top of the mounting bracket 12 is in an inverted state. This electric telescopic rod 13 shortens, and its bottom drives the corresponding connecting plate. The top of the first 15 moves upward, driving the support plate 11 to rotate via the mounting block 14, which in turn drives the condenser tube 10 and the rotating tube plate 202 to rotate synchronously. Another electric telescopic rod 13, installed on the inner wall of the bottom of the mounting frame 12, shortens. Its top, via the corresponding connecting plate 15, drives the mounting block 14 on the other side, similarly driving the support plate 11, condenser tube 10, and rotating tube plate 202 to rotate. Both support plates 11 rotate in the same direction. During rotation, when the oil reservoir 201 is not full, the position of the condenser tube 10 continuously changes, constantly adjusting its contact position with the oil in the oil reservoir 201 to ensure that the oil enters all condenser tubes 10 evenly. The oil then flows within the condenser tubes 10 and finally enters another oil reservoir 201, before exiting through the outlet. When the coolant is discharged from pipe 204, the electric telescopic rod 13 extends and retracts, driving the inlet pipe 201 to move vertically within the inlet pipe 16 via the connecting plate 203. The one-way valve 18, installed at the bottom of the inner circumference of the inlet pipe 201, moves accordingly, allowing new coolant to enter the cavity through the inlet pipe 16 and the one-way valve 18. In another linkage assembly, the electric telescopic rod 13 drives the outlet pipe 202 to move vertically within the outlet pipe 17 via the connecting plate 203. The one-way valve 18, installed at the top of the inner circumference of the outlet pipe 202, moves synchronously, discharging the old coolant from the cavity through the outlet pipe 17 and the one-way valve 18. The two one-way valves 18 move in the same direction to ensure the coolant flows in the set direction. When the inlet pipe 201 extends and retracts within the inlet pipe 16... When moving vertically inside, the leak-proof pad 401 at the top of the inner circumference of inlet pipe 16 remains in contact with the top of the outer circumference of inlet pipe 2 301, while the leak-proof pad 402 at the bottom of the outer circumference of inlet pipe 2 301 remains in contact with the bottom of the inner circumference of inlet pipe 16. This prevents coolant leakage at the gap between inlet pipe 16 and inlet pipe 2 301. Simultaneously, as outlet pipe 2 302 moves vertically inside outlet pipe 17, the leak-proof pad 401 at the bottom of the inner circumference of outlet pipe 17 remains in contact with the bottom of the outer circumference of outlet pipe 2 302, and the leak-proof pad 402 at the top of the outer circumference of outlet pipe 2 302 remains in contact with the top of the inner circumference of outlet pipe 17. This prevents coolant leakage at the gap between outlet pipe 17 and outlet pipe 2 302.During the rotation of the two support plates 11, the outer circumference of the sealing gasket 501 on the side closest to each other remains in close contact with the inner circumference of the cylinder 1, ensuring the sealing of the cavity and ensuring that the coolant always exchanges heat with the condenser tube 10 within the cavity. The spiral stirring plate 701 on the edge of the support plates 11 on the side closest to each other rotates simultaneously, generating a spiral thrust on the coolant within the cavity, causing the coolant to flow along a spiral path, accelerating the mixing of newly injected coolant with the existing coolant, enhancing the turbulence of the coolant, and allowing the coolant to contact the condenser tube 10 more fully. Combined with the up-and-down movement of the one-way valve 18, dynamic replacement of the coolant is achieved, thereby more efficiently removing heat from the high-temperature oil in the condenser tube 10. This realizes enhanced heat exchange through the rotation of the condenser tube, while simultaneously dynamically replacing the coolant, improving the heat exchange effect and cooling uniformity.
