Description

Technical Field

[0002] In the modern industrial field, hydraulic equipment is widely used in many industries such as construction machinery, metallurgy, aerospace, etc. due to its efficient power transmission and precise control performance. With the continuous development of hydraulic equipment towards high pressure, high speed, and high power, a large amount of heat will be generated by hydraulic oil during operation due to factors such as friction and work done. If these heats cannot be dissipated in time and effectively, the temperature of the hydraulic oil will continue to rise, resulting in a decrease in its viscosity and a deterioration of lubrication performance, thereby increasing the wear of internal components of the hydraulic equipment and reducing the service life of the equipment.

[0003] Currently, traditional heat dissipation devices often adopt simple heat dissipation structures, such as single heat dissipation tubes or heat dissipation fins. The heat dissipation area is limited and the heat exchange efficiency is relatively low, making it difficult to meet the requirements of modern hydraulic equipment for rapid heat dissipation. Moreover, the heat dissipation effect of these devices is greatly affected by environmental factors, and the heat dissipation performance will decrease significantly in high-temperature or poorly ventilated working environments.

[0016] (III) Beneficial effects

[0017] The present invention provides a hydraulic oil heat dissipation device for hydraulic equipment. It has the following beneficial effects:

[0018] (I) The hydraulic oil heat sink for hydraulic equipment increases the heat dissipation area by setting a cooling component and combining an inner tube, an outer tube, a temperature conducting block, a main heat sink, an auxiliary heat sink and heat sink fins, and has a good heat conduction effect. The fan impeller of the fan component rotates to generate airflow, accelerates the heat exchange between the air and the heat sink, and forces convection to take away the heat, thereby realizing rapid cooling of the hydraulic oil. Compared with traditional heat sinks, the heat dissipation efficiency is significantly improved, which can effectively ensure that the hydraulic oil works at a suitable temperature and improve the performance and stability of the hydraulic equipment.

[0019] (2). The hydraulic oil cooling device for a hydraulic equipment can adjust the position of the baffle plate in the baffle component through a snap connection. The baffle component can cover the cooling component to restrict the air flow direction, adjust the distribution of the air flow in the cooling component, make it enter more evenly, and improve the cooling effect. The baffle ring further guides the air flow to avoid the influence of the air flow on the temperature of the hydraulic oil in the liquid inlet pipe. Based on the principle of fluid mechanics, the air flow direction is optimized and can be flexibly adjusted according to the actual working conditions to ensure the efficient operation of the cooling device under different conditions.

[0020] (3). The hydraulic oil cooling device for a hydraulic equipment can effectively intercept impurities such as metal particles and oil stains in the hydraulic oil through the filter screen on the mounting ring of the filter component. The mounting ring with magnetic adsorption ensures the stable installation of the filter screen, ensures the cleanliness of the hydraulic oil. The clean hydraulic oil can reduce the wear of internal components of the hydraulic equipment, extend the service life of the equipment, reduce the probability of equipment failures, and improve the reliability and stability of the equipment.

[0021] (4). The hydraulic oil cooling device for a hydraulic equipment can utilize the flow of the hydraulic oil to push the guide vane, drive the rotating disk and the lever to rotate, and the lever can push the impurities on the filter screen to fall off, realizing self-cleaning, avoiding the blockage of the filter screen, and ensuring the continuity of the filtering effect.

The main heat sink 45 and the secondary heat sink 47 increase the heat dissipation area and improve the heat dissipation efficiency.

[0036] The outer wall of the secondary heat sink 47 is inserted into the inner wall of the main heat sink 45 through a limiting buckle 48, and the outer wall of the limiting buckle 48 is inserted into the inner wall of the main heat sink 45.

A magnetic force acts between the magnetic attraction blocks 84 on the blade wheel 83 and the permanent magnets 85 on the fan impeller 86. Due to the principle of opposite poles attracting each other, the fan impeller 86 rotates as the blade wheel 83 rotates. When the fan impeller 86 rotates, according to the principle of aerodynamics, its blades push the air to flow, forming an air current.

[0038] The flow blocking assembly 5 includes a liquid inlet pipe 51. A fixing ring 54 is fixedly connected to the outer wall of the liquid inlet pipe 51. A flow blocking ring 55 is fixedly connected to one side of the fixing ring 54 away from the liquid inlet pipe 51. A flow blocking plate 53 is slidably connected to the inner wall of the fixing ring 54, and the flow blocking plates 53 are arranged in a circular array along the central axis of the fixing ring 54. A buckle 52 is clamped to the outer wall of the flow blocking plate 53, and the outer wall of the buckle 52 is fixedly connected to the outer wall of the fixed shell 1. The outer wall of the liquid inlet pipe 51 is fixedly connected to the inner wall of the inner tube 41. Since a partition plate is arranged at the inlet end of the liquid inlet pipe 51, the incoming hydraulic oil is dispersed into four groups and enters the middle of the liquid inlet pipe 51. Since the stepper motor 81 is arranged inside the liquid inlet pipe 51, the hydraulic oil needs to be dispersed so as not to block the normal operation of the stepper motor 81, and then it flows out from the end of the hydraulic oil.

[0039] The filtering assembly 6 includes a liquid outlet pipe 61. An installation ring 62 is magnetically adsorbed on the inner wall of the liquid outlet pipe 61. A filter screen 63 is fixedly connected to the outer wall of the installation ring 62. A limiting plate 65 is fixedly connected to the outer wall of the liquid outlet pipe 61.

[0040] The self-cleaning component 7 includes a fixing frame 73. A rotating disk 71 is rotatably connected to the inner wall of the fixing frame 73. A conical block 74 is fixedly connected to one side of the rotating disk 71 close to the fixing frame 73. A guiding vane 75 is fixedly connected to the outer wall of the conical block 74, and the guiding vanes 75 are arranged in a circular array along the central axis of the conical block 74. A dial rod 72 is fixedly connected to the outer wall of the rotating disk 71, and the dial rods 72 are arranged in a circular array along the central axis of the rotating disk 71. The flow of the hydraulic oil pushes the guiding vanes 75 on the conical block 74. According to the principle of fluid dynamics, the guiding vanes 75 are rotated by the impact force of the hydraulic oil, thereby driving the rotating disk 71 to rotate within the fixing frame 73. When the rotating disk 71 rotates, the dial rods 72 on its outer wall rotate along with it. The dial rods 72 are in sliding contact with the outer wall of the filter screen 63, and can peel off the impurities intercepted on the filter screen 63. The outer wall of the fixing frame 73 is fixedly connected to the inner wall of the liquid outlet pipe 61. The outer wall of the dial rod 72 is slidably connected to the outer wall of the filter screen 63.

[0041] The hydraulic oil cooling device mainly consists of a fixing shell 1, an integrated component 2, and a separation component 3. The outer wall of the integrated component 2 is fixedly connected to the outer wall of the fixing shell 1, and it internally includes a flow-blocking component 5, a fan component 8, and a cooling component 4; the outer wall of the separation component 3 is inserted into the inner wall of the flow-blocking component 5, and it consists of a filtering component 6 and a self-cleaning component 7. Before using the cooling device, the cooling device needs to be installed on the hydraulic oil pipeline. It should be noted that the installation direction of the cooling device is that the hydraulic oil transported from the hydraulic pump to the hydraulic equipment needs to enter the cooling device from the fixing shell 1 and flow out of the cooling device from the self-cleaning component 7. The hydraulic oil enters the device from the liquid inlet pipe 51 of the flow-blocking component 5, passes through the cooling component 4 and the filtering component 6 in sequence, and finally flows out of the device, achieving heat dissipation, filtration, and self-cleaning during this process.

[0042] The flow-blocking component 5 includes a liquid inlet pipe 51, a fixing ring 54, a flow-blocking ring 55, flow-blocking plates 53, and a buckle 52. The outer wall of the liquid inlet pipe 51 is fixedly connected to the fixing ring 54. The flow-blocking ring 55 is fixedly connected to one side of the fixing ring 54 away from the liquid inlet pipe 51. A plurality of flow-blocking plates 53 arranged in a circular array along its central axis are slidably connected to the inner wall of the fixing ring 54. The outer walls of the flow-blocking plates 53 are clamped to the outer wall of the fixing shell 1 through the buckle 52. The outer wall of the liquid inlet pipe 51 is fixedly connected to the inner wall of the inner pipe 41 of the cooling component 4.

[0043] When the hydraulic oil enters the flow-blocking component 5 from the liquid inlet pipe 51, since a partition plate is provided at the inlet end of the liquid inlet pipe 51, the incoming hydraulic oil is dispersed into four groups and enters the middle of the liquid inlet pipe 51. Since the stepping motor 81 is arranged inside the liquid inlet pipe 51, the hydraulic oil needs to be dispersed so as not to block the normal operation of the stepping motor 81, and then flows out from the end of the hydraulic oil.

[0044] The fan assembly 8 is composed of a stepper motor 81, a rotating shaft 82, a vane wheel 83, magnetic attraction blocks 84, a fan impeller 86 and a permanent magnet 85. The outer wall of the stepper motor 81 is fixedly connected to the inner wall of the inner tube 41 through a frame, and its output end is fixedly connected to the vane wheel 83 through the rotating shaft 82. A plurality of magnetic attraction blocks 84 arranged in a circular array along its central axis are fixedly connected to the outer wall of the vane wheel 83. The fan impeller 86 is arranged outside the vane wheel 83, and a plurality of permanent magnets 85 arranged in a circular array along its central axis are fixedly connected to its outer wall. The inner wall of the fan impeller 86 is slidably connected to the limiting block 42 on the inner wall of the inner tube 41.

[0045] After the stepper motor 81 is powered on, it drives the rotating shaft 82 to rotate, and then drives the vane wheel 83 to rotate. A magnetic force is generated between the magnetic attraction blocks 84 on the vane wheel 83 and the permanent magnets 85 on the fan impeller 86. Due to the principle of opposite poles attracting each other, the fan impeller 86 rotates with the rotation of the vane wheel 83. When the fan impeller 86 rotates, according to the principle of aerodynamics, its blades push the air to flow, forming an air flow. When the air flow passes through the main heat sink 45, the secondary heat sink 47 and the heat dissipation fins 49 of the cooling component 4, it accelerates the heat exchange between the air and the heat sink, taking away the heat on the heat sink, thereby realizing the cooling of the hydraulic oil. The inner wall of the fan impeller 86 is slidably connected to the limiting block 42, ensuring the stability and accuracy of the rotation of the fan impeller 86, and preventing it from shifting or shaking during the rotation process, which may affect the heat dissipation effect.

[0046] Moreover, by adjusting the position of the baffle 53 on the flow blocking component 5 and using the buckle 52 to fix the position of the baffle 53, the baffle 53 is forced to cover the cooling component 4, thereby restricting the movement direction of the air flow, adjusting the distribution of the air flow in the cooling component 4, making it enter the cooling component 4 more evenly, and improving the heat dissipation effect. The baffle ring 55 further blocks and guides the flow of the air flow, ensuring that the air flow flows along the predetermined path, avoiding the air flow passing through the cooling component 4 from blowing to the end of the liquid inlet pipe 51, which may affect the temperature of the hydraulic oil in the liquid inlet pipe 51, and improving the stability and efficiency of the heat dissipation device. Its principle is based on the control of fluid flow in fluid mechanics. By reasonably setting the baffle 53 and the baffle ring 55, the flow direction of the air flow is changed to achieve the purpose of optimizing heat dissipation.

[0047] The cooling component 4 includes an inner tube 41, an outer tube 46, a heat conduction block 44, a limiting post 43, a main heat sink 45, a secondary heat sink 47, a limiting buckle 48 and heat dissipation fins 49. The outer wall of the inner tube 41 is fixedly connected to the outer tube 46. The outer wall of the outer tube 46 is fixedly connected with a plurality of heat conduction blocks 44 arranged in a circumferential array along its central axis. The outer wall of the heat conduction block 44 is inserted with the limiting post 43. The outer walls of the limiting post 43 are respectively inserted with the main heat sink 45 and the secondary heat sink 47. The outer wall of the secondary heat sink 47 is inserted into the inner wall of the main heat sink 45 through the limiting buckle 48. The inner wall of the secondary heat sink 47 is fixedly connected with a plurality of heat dissipation fins 49 arranged in a circumferential array along its central axis. The inner wall of the inner tube 41 is fixedly connected with a limiting block 42. The outer wall of the outer tube 46 is in contact with the outer walls of the main heat sink 45 and the secondary heat sink 47.

[0048] The hydraulic oil that needs to be cooled flows in from the liquid inlet pipe 51. Since the temperature of the hydraulic oil is higher than the external ambient temperature, according to the principle of heat conduction, heat will be transferred from the hydraulic oil through the pipe wall of the inner tube 41 outside the liquid inlet pipe 51 to the outer tube 46. The heat conduction blocks 44 on the outer wall of the outer tube 46 can effectively export the heat and transfer it to the main heat sink 45 and the secondary heat sink 47. The main heat sink 45 and the secondary heat sink 47 increase the heat dissipation area and improve the heat dissipation efficiency. The heat dissipation fins 49 on the secondary heat sink 47 further increase the contact area between the air and the heat sink, enabling the heat to be dissipated into the air faster. The air flow generated by the fan assembly 8 accelerates this heat dissipation process. Through forced convection, the heat on the heat sink is taken away to achieve the cooling of the hydraulic oil. The limiting post 43 and the limiting buckle 48 ensure the stable installation of the main heat sink 45, the secondary heat sink 47 and the heat dissipation fins 49, preventing them from loosening or displacing during the working process. In addition, when the main heat sink 45 and the secondary heat sink 47 need to be replaced, only need to pull out the limiting post 43, and then slide the limiting buckle 48 out of the main heat sink 45, then the main heat sink 45 and the secondary heat sink 47 can be taken out from the cooling component 4.

[0049] The filtering component 6 includes an outlet pipe 61, a mounting ring 62, a filter screen 63, a limiting plate 65 and a rubber pad 64. The inner wall of the outlet pipe 61 magnetically adsorbs the mounting ring 62. The outer wall of the mounting ring 62 is fixedly connected with the filter screen 63. The outer wall of the outlet pipe 61 is fixedly connected with the limiting plate 65 and a plurality of rubber pads 64 arranged in a circumferential array along its central axis. The outer wall of the limiting plate 65 is clamped with the fixing block 66 through a clamping ball 67. The outer wall of the fixing block 66 is fixedly connected with the outer wall of the fixing ring 54. The outer wall of the outlet pipe 61 is inserted into the inner wall of the inlet pipe 51.

[0050] The hydraulic oil that has been cooled by the cooling component 4 flows into the outlet pipe 61. When the hydraulic oil passes through the outlet pipe 61, due to the existence of the filter screen 63 on the mounting ring 62, according to the filtering principle, impurities in the hydraulic oil such as metal particles and oil stains are intercepted by the filter screen 63, thereby achieving the filtration of the hydraulic oil and ensuring the cleanliness of the hydraulic oil.

[0051] When the filter screen 63 needs to be replaced, just grasp the rubber pad 64 and rotate the liquid outlet pipe 61 to force the clamping ball 67 to slide out of the limit plate 65. Then, the liquid outlet pipe 61 can be taken out of the liquid inlet pipe 51. It should be noted that before replacing the filter screen 63, the operation of the hydraulic equipment and the hydraulic pump must be stopped, and then the filter screen 63 can be replaced. After the filter screen 63 is replaced, the limit plate 65 and the fixing block 66 are clamped by the clamping ball 67, so that the filter assembly 6 can be stably installed in the device, which is convenient for disassembly and maintenance and facilitates the regular replacement of the filter screen 63.

[0052] The self-cleaning component 7 includes a fixing frame 73, a rotating disk 71, a conical block 74, a guide vane 75 and a lever 72. The outer wall of the fixing frame 73 is fixedly connected to the inner wall of the liquid outlet pipe 61. The inner wall of the fixing frame 73 is rotatably connected to the rotating disk 71. A conical block 74 is fixedly connected to one side of the rotating disk 71 close to the fixing frame 73. A plurality of guide vanes 75 arranged in an annular array along its central axis are fixedly connected to the outer wall of the conical block 74. A plurality of levers 72 arranged in an annular array along its central axis are fixedly connected to the outer wall of the rotating disk 71. The outer wall of the lever 72 is slidably connected to the outer wall of the filter screen 63.

[0053] When the hydraulic oil flows through the liquid outlet pipe 61, the flow of the hydraulic oil pushes the guide vanes 75 on the conical block 74. According to the principle of fluid dynamics, the guide vanes 75 rotate under the impact force of the hydraulic oil, and then drive the rotating disk 71 to rotate in the fixing frame 73. When the rotating disk 71 rotates, the lever 72 on its outer wall rotates accordingly. The lever 72 is in sliding contact with the outer wall of the filter screen 63, and can peel off the impurities intercepted on the filter screen 63. The peeled impurities converge at the tail of the filter screen 63 under the flow of the hydraulic oil, realizing the self-cleaning of the filter screen 63. This self-cleaning method can avoid the blockage of the filter screen 63, ensure the continuity of the filtering effect, and reduce the frequency and cost of manual maintenance.

[0054] After completing one operation of heat dissipation, filtration and self-cleaning of the hydraulic oil, the hydraulic oil flows out of the device from the liquid outlet pipe 61 and returns to the hydraulic system. When the hydraulic system runs again and the temperature of the hydraulic oil rises and needs heat dissipation, the above work process is repeated. During the whole work process, the flow blocking component 5 adjusts the flow of the hydraulic oil, the fan component 8 accelerates heat dissipation, the temperature reduction component 4 realizes heat exchange, the filter component 6 filters impurities, and the self-cleaning component 7 maintains the cleanliness of the filter screen 63. The components cooperate with each other to form an efficient and stable closed-loop system, ensuring the normal working temperature and cleanliness of the hydraulic oil in the hydraulic equipment, and improving the overall performance and reliability of the hydraulic equipment.
