Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydraulic station technology, specifically to a high-efficiency heat dissipation oil tank structure for hydraulic stations. Background Technology
[0002] A hydraulic power unit is a hydraulic source device or a hydraulic device including control valves, consisting of a hydraulic pump, a drive motor, an oil tank, a directional valve, a throttle valve, and a relief valve. It supplies oil according to the flow direction, pressure, and flow rate required by the drive device. It is suitable for various machines where the drive device and the hydraulic power unit are separate. By connecting the hydraulic power unit and the drive device (cylinder or motor) with oil pipes, the hydraulic system can realize various specified actions.
[0003] During operation, the hydraulic oil in a hydraulic station is prone to overheating due to frequent movements or high-pressure environments. This reduces the viscosity-temperature properties and lubrication performance of the oil, affecting the stability of the hydraulic station. Traditional cooling is achieved through air cooling, while some devices use internal inlet pipes, outlet pipes, straight cooling pipes, multiple sets of cooling hoses, and U-shaped pipes. The hose sets increase the contact area between the hydraulic oil and the coolant, improving heat exchange efficiency.
[0004] Existing hydraulic power units typically employ relatively simple heat dissipation methods. Air-cooled cooling requires continuous operation of the fan, resulting in high energy consumption. In contrast, the cooling efficiency of circulating water-cooled cooling decreases significantly after prolonged use as the cooling water temperature rises. Although using both methods together can maintain cooling for an extended period, it does not solve the problem of high energy consumption associated with air-cooled cooling. Utility Model Content
[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a high-efficiency heat dissipation oil tank structure for hydraulic stations, which can effectively solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] This utility model provides a high-efficiency heat dissipation oil tank structure for a hydraulic station, including an outer shell. An oil passage block is fixed to the top of the outer wall of the outer shell. A water tank is fixed to the middle of one side of the outer shell. An inlet pipe and an outlet pipe are fixed to both ends of the water tank. A breathable mesh plate is fixed through the upper and lower parts of the middle of both sides of the outer shell. A cooling box is fixed to the middle of the inner wall of the outer shell. The inlet pipe and the outlet pipe are respectively sealed and connected through the two ends of the cooling box. A first oil guide pipe is provided inside the cooling box. Oil pipe joints are fixed to both ends of the first oil guide pipe. Both oil pipe joints are connected to the oil passage block through a second oil guide pipe. Vertical heat-guiding fins are connected through the top of the cooling box. A water pump is installed through the water tank near the outer shell. A T-shaped pipe is fixed to the outlet of the water pump. Spray pipes are fixed to both ends of the T-shaped pipe.
[0008] Furthermore, the first oil guide pipe is U-shaped, and multiple vertical heat-conducting fins are provided. The multiple vertical heat-conducting fins are arranged horizontally and equidistantly in the middle of the U-shape of the first oil guide pipe, and horizontal heat-conducting fins are fixed on both the top and bottom sides of the multiple vertical heat-conducting fins.
[0009] Furthermore, both spray pipes are fixed to the inner wall of the outer shell, and the two spray pipes are respectively located at the top and bottom of the plurality of vertical heat-guiding fins. Atomizing spray holes are horizontally and equidistantly opened on opposite sides of the two spray pipes.
[0010] Furthermore, servo motors are fixed above and below the middle of the inner wall of the outer shell near the water tank, and the two servo motors are respectively located on the same horizontal plane as the upper and lower middle of the vertical heat guide fins.
[0011] Furthermore, the power output end of the servo motor is fixed with a wind duct, and the other end of the wind duct is rotatably connected to one side of the inner wall of the outer shell. The two wind ducts are respectively located on the same horizontal plane as the two breathable mesh plates located on the same vertical plane.
[0012] Furthermore, a water injection pipe is sealed and connected through one side of the top of the water tank, the water tank is made of acrylic sheet, and a circulation pump is installed inside the water tank.
[0013] Furthermore, a liquid thermometer is fixed to one side of the outer wall of the outer shell, and a light sensor is fixed to one side of the liquid thermometer. There are three light sensors, which are arranged vertically at equal intervals. The three light sensors are used in conjunction with the internal circulation pump, water pump and servo motor of the water tank from bottom to top.
[0014] The technical solution provided by this utility model has the following advantages compared with the known prior art:
[0015] 1. This application operates through a circulating pump inside the water tank, circulating the water inside the cooling tank. The water inside the cooling tank absorbs the heat from the first oil guide pipe, achieving initial water cooling. The evaporation of water mist absorbs the heat from both ends of the vertical heat-conducting fins. The heat-conducting fins conduct the heat inside the cooling tank to the external environment. The sprayed water mist cools the area. The servo motor drives the fan to rotate, and the airflow accelerates the evaporation of water mist outside the heat-conducting fins, rapidly cooling the fins. This achieves triple heat dissipation, thus achieving multiple heat dissipation methods, ensuring that the hydraulic oil inside the hydraulic station remains at a low temperature even after prolonged operation.
[0016] 2. This application uses a liquid thermometer to detect the internal temperature of the outer casing. When the temperature rises, the liquid level inside the liquid thermometer rises. At this time, the bottom photosensitive sensor is blocked by the liquid level and sends a signal to control the circulation pump inside the water tank to work. As the temperature continues to rise, the middle photosensitive sensor is blocked by the liquid level and controls the water pump to work. When the temperature continues to rise, the top photosensitive sensor is blocked by the liquid level. At this time, the servo motor works to drive the fan to rotate, thereby achieving the effect of automatically adjusting the heat dissipation method according to the hydraulic oil temperature.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0026] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.
[0027] This application discloses a high-efficiency heat dissipation oil tank structure for a hydraulic station, including an outer shell 1. An oil passage block 2 is fixed to the top of the outer wall of the outer shell 1. A water tank 3 is fixed to the middle of one side of the outer wall of the outer shell 1. An inlet pipe 6 and an outlet pipe 7 are fixed to both ends of the water tank 3, respectively. A breathable mesh plate 14 is fixed through the middle of the middle of both sides of the outer shell 1. A cooling box 8 is fixed to the middle of the inner wall of the outer shell 1. The inlet pipe 6 and the outlet pipe 7 are respectively sealed and connected through the two ends of the cooling box 8. A first oil guide pipe 11 is provided inside the cooling box 8. An oil pipe connector 12 is fixed to both ends of the first oil guide pipe 11. Both oil pipe connectors 12 are connected to the oil passage block 2 through a second oil guide pipe 13. A vertical heat-guiding fin 9 is connected through the top of the cooling box 8. A water pump 17 is installed through the water tank 3 near the side of the outer shell 1. A three-way pipe 18 is fixed to the outlet end of the water pump 17. Spray pipes 19 are fixed to both ends of the three-way pipe 18.
[0028] Reference Appendix Figure 4 The first oil guide pipe 11 is U-shaped, and multiple vertical heat-conducting fins 9 are provided. The multiple vertical heat-conducting fins 9 are arranged horizontally and equally at the middle of the U-shape of the first oil guide pipe 11. Horizontal heat-conducting fins 10 are fixed on the top and bottom sides of the multiple vertical heat-conducting fins 9. The vertical heat-conducting fins 9 absorb the heat of the cooling water near the first oil guide pipe 11, and the horizontal heat-conducting fins 10 are used to accelerate the heat dissipation of the parts of the vertical heat-conducting fins 9 located outside the cooling box 8.
[0029] Reference Appendix Figure 3 Two spray pipes 19 are fixed to the inner wall of the outer shell 1. The two spray pipes 19 are located at the top and bottom of multiple vertical heat-conducting fins 9 respectively. Atomizing nozzles 20 are opened horizontally and equidistantly on opposite sides of the two spray pipes 19. Water is pumped out of the water tank 3 by the water pump 17 and then introduced into the two spray pipes 19 through the three-way pipe 18. The water is then evenly sprayed onto the vertical heat-conducting fins 9 and the horizontal heat-conducting fins 10 through the atomizing nozzles 20. The water mist absorbs the heat at both ends of the vertical heat-conducting fins 9 through evaporation.
[0030] Reference Appendix Figure 2The outer shell 1 has two servo motors 15 fixed above and below the middle of the inner wall near the water tank 3. The two servo motors 15 are located on the same horizontal plane as the upper and lower middle of the vertical heat-conducting fins 9, respectively. The power output end of the servo motor 15 is fixed with a fan duct 16. The other end of the fan duct 16 is rotatably connected to one side of the inner wall of the outer shell 1. The two fan ducts 16 are located on the same horizontal plane as two breathable mesh plates 14 located on the same vertical plane. The two servo motors 15 drive the fan ducts 16 to rotate, drawing in air from outside the outer shell 1 through the breathable mesh plate 14, blowing it over multiple vertical heat-conducting fins 9, and then expelling it from the other breathable mesh plate 14. The wind accelerates the evaporation of water mist outside the heat-conducting fins, achieving rapid cooling of the heat-conducting fins.
[0031] Reference Appendix Figure 1 The top side of the water tank 3 is sealed with a water injection pipe 4. The water tank 3 is made of acrylic sheet and has a circulation pump inside. The remaining water level inside the water tank 3 can be seen through the acrylic sheet, so it can be determined whether cooling water needs to be added. When water needs to be added, water can be injected into the tank through the water injection pipe 4.
[0032] Reference Appendix Figure 5 The outer shell 1 has a liquid thermometer 5 fixed to one side of its outer wall, and a light sensor 51 fixed to one side of the liquid thermometer 5. There are three light sensors 51 arranged vertically at equal intervals. The three light sensors 51 are used in conjunction with the internal circulation pump, water pump 17 and servo motor 15 of the water tank 3 from bottom to top. During normal operation, the liquid thermometer 5 detects the internal temperature of the outer shell 1. When the temperature rises, the liquid level inside the liquid thermometer 5 rises. At this time, the bottom light sensor 51 is blocked by the liquid level and sends a signal to control the internal circulation pump of the water tank 3 to work for initial water cooling. As the temperature continues to rise, the middle light sensor 51 is blocked by the liquid level and controls the water pump 17 to work to spray water mist for cooling. When the temperature continues to rise, the top light sensor 51 is blocked by the liquid level. At this time, the servo motor 15 works to drive the fan duct 16 to rotate, realizing triple heat dissipation.
[0033] The workflow of this utility model is as follows:
[0034] During normal operation, the liquid thermometer 5 detects the internal temperature of the outer casing 1. When the temperature rises, the liquid level inside the liquid thermometer 5 rises. At this time, the bottom photosensitive sensor 51 is blocked by the liquid level and sends a signal to control the circulation pump inside the water tank 3 to work. The water inside the cooling tank 8 circulates and absorbs the heat from the first oil guide pipe 11, achieving initial water cooling. As the temperature continues to rise, the middle photosensitive sensor 51 is blocked by the liquid level, controlling the water pump 17 to work. The water pump 17 draws out some water from the water tank 3 and introduces it into the two spray pipes 19 through the three-way pipe 18. Then, it is evenly sprayed from the atomizing nozzles 20 onto the vertical heat-conducting fins 9 and the horizontal heat-conducting fins 10. The water is absorbed through evaporation. The system collects heat from both ends of the vertical heat-conducting fins 9, which in turn absorb heat from inside the cooling box 8. Water mist is sprayed to cool the fins, achieving a double-layer cooling effect. When the temperature continues to rise, the top light sensor 51 is blocked by the liquid level. At this time, the servo motor 15 works to drive the fan duct 16 to rotate. The two servo motors 15 drive the fan duct 16 to rotate, drawing air from outside the outer shell 1 through the ventilated mesh plate 14, blowing it over multiple vertical heat-conducting fins 9, and then expelling it from the ventilated mesh plate 14 on the other side. The wind accelerates the evaporation of water mist outside the heat-conducting fins, rapidly cooling the fins and achieving triple heat dissipation. The water tank 3, made of acrylic sheet, shows the remaining water level inside, allowing you to determine if cooling water needs to be added. When water needs to be added, simply inject water into the tank through the water inlet pipe 4.
[0035] The aforementioned optical sensor model can be LX-120, which can send control signals based on light intensity.
