A wind power hydraulic oil cooling device

Abstract

The present invention provides a wind power hydraulic oil cooling device, which belongs to the technical field of wind power equipment. The device comprises a radiator and a plurality of heat sinks. The heat sinks are sleeved on the outer side of the heat transfer oil pipe to form a heat dissipation array. A fan is arranged on one side of the heat transfer array. A cooling water pipe is wrapped inside the heat transfer oil pipe, and the heat transfer oil pipe is wrapped by a water absorption net. The water absorption net is wrapped on the heat transfer oil pipe at the gap between the heat transfer fins, and a cooling water pipe for conveying cooling water to the water absorption net is arranged. When the water absorption net absorbs water, heat exchange can be generated with the heat transfer oil pipe. Since the specific heat capacity of water is greater than that of air, more heat can be absorbed. At the same time, the continuous blowing of airflow by the fan can evaporate the water on the water absorption net and take away the heat, thereby improving the heat dissipation performance of the surface of the heat transfer oil pipe, and then improving the overall heat dissipation efficiency of the radiator to meet higher heat dissipation requirements.

Description

Technical Field

[0001] The invention belongs to the technical field of wind power equipment, and in particular relates to a wind power hydraulic oil cooling device. Background Art

[0002] Wind turbine generators are mainly composed of wind turbine blades, gearboxes, generators, hydraulic brakes and other parts. Among them, gearboxes and hydraulic brakes require circulating hydraulic oil. When the equipment is running, the temperature of the hydraulic oil will continue to rise. The increase in the temperature of the hydraulic oil will lead to a decrease in viscosity, oxidation and deterioration of the oil, and a decrease in oil performance. A sharp increase in oil temperature may cause system performance to decline or even fail. Cooling the hydraulic oil helps keep the oil temperature within a reasonable range, thereby ensuring the stable operation of the system.

[0003] At present, water mist is generally sprayed on the fins and oil pipes. As the fan continues to blow air, the water attached to the fins and oil pipes evaporates and takes away the heat, thereby improving the heat dissipation effect. Although the direct spraying method can make water droplets adhere to the fins and oil pipes, there are a lot of heat dissipation gaps between the fins and copper pipes. When spraying water mist, the water mist will be lost from the gaps, resulting in a large amount of water consumption.

[0004] In actual use, the heat on the fins is transferred by the oil pipe. Compared with the oil pipe directly wrapped with high-temperature oil, the fin temperature is lower. Due to the large surface area of ​​the fins, the fins dissipate heat faster, while the area where the oil pipe does not contact the fins dissipates heat more slowly. Therefore, the overall heat dissipation efficiency can be improved by increasing the heat dissipation speed of the oil pipe. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a wind power hydraulic oil cooling device, which at least partially solves the above problems.

[0006] The technical solution adopted by the present invention is as follows: The present invention proposes a wind power hydraulic oil cooling device, including a radiator, the radiator includes a plurality of mutually parallel heat transfer oil pipes, and two adjacent heat transfer oil pipes are connected by a connecting oil pipe:

[0007] A plurality of heat dissipation fins are sleeved on the outside of the heat-conducting oil pipe to form a heat dissipation array, and a fan is provided on one side of the heat dissipation array;

[0008] Wherein, the interior of the heat transfer oil pipe is wrapped with a cooling water pipe, and two adjacent cooling water pipes are connected by a connecting water pipe;

[0009] An installation gap is provided on one side of the heat transfer oil pipe, and a plurality of overflow holes distributed along the axial direction are provided on one side of the cooling water pipe located in the installation gap. Water absorption strips and sealing strips distributed circumferentially along the cooling water pipe are provided in the installation gap. The heat transfer oil pipe, the water absorption strips and the sealing strips are wrapped together by a water absorption net. The cooling water pipe is configured to be able to rotate along its own axis, and the overflow holes are sealed or drained when rotated to different angles.

[0010] Furthermore, the water absorption net is provided with a plurality of heat conduction gaps distributed along the axial direction and corresponding to the heat dissipation fins.

[0011] Furthermore, it also includes a driving device arranged at one end of the cooling water pipe, and the driving device is used to drive the multiple cooling water pipes to rotate synchronously. The driving device includes a motor, a worm and a worm wheel. The same end of the multiple cooling water pipes is coaxially fixed with a worm wheel. The worm is fixed to the output end of the motor, and the multiple worm wheels are engaged with the worm.

[0012] Furthermore, it also includes a cooling water circulation machine, which is provided with a water inlet pipe and a water return pipe, and the water inlet pipe and the water return pipe are respectively connected to the two cooling water pipes located at the outermost sides.

[0013] Furthermore, it also includes a water tank and a water pump, and the water tank replenishes water to the cooling water circulation machine through the water pump.

[0014] Furthermore, the radiator is provided with an oil inlet pipe and an oil drain pipe, and the oil inlet pipe and the oil drain pipe are respectively connected to the two heat-conducting oil pipes located at the outermost sides.

[0015] Furthermore, an oil pump is provided on the oil inlet pipe.

[0016] Furthermore, a filter is provided on the oil drain pipe.

[0017] Furthermore, it also includes a support frame for supporting the heat dissipation array, and connecting seats corresponding to the cooling water pipes are fixed to the inner walls on both sides of the support frame, and both ends of the cooling water pipes are rotatably connected to the connecting seats.

[0018] Furthermore, the connecting water pipe, the water inlet pipe and the water return pipe are all made of rubber hoses.

[0019] The beneficial effects achieved by the present invention using the above structure are as follows:

[0020] 1. By wrapping a water absorption net on the heat transfer oil pipe at the gap of the heat dissipation fins, and setting a cooling water pipe to transport cooling water to the water absorption net, when the water absorption net absorbs water, it can generate heat exchange with the heat transfer oil pipe. Since the specific heat capacity of water is larger than that of air, it can absorb more heat. At the same time, the continuous blowing of the fan can evaporate the water on the water absorption net and take away the heat, thereby improving the heat dissipation performance of the surface of the heat transfer oil pipe, and then improving the overall heat dissipation efficiency of the radiator, meeting higher heat dissipation requirements, and compared with directly spraying cooling water, the water absorption and covering method of the water absorption net can reduce water consumption;

[0021] 2. By setting the cooling water pipe for transporting cooling water to be wrapped by the thermal oil pipe, a heat exchange channel can be formed between the inner side of the thermal oil pipe and the cooling water pipe, and the cooling water in the cooling water pipe can be circulated through the cooling water circulation machine to form a circulating water circuit. Therefore, the cooling water pipe can cool the inner side of the thermal oil pipe and increase the heat dissipation area of ​​the thermal oil pipe. By optimizing the pipeline, the heat absorption performance of the cooling water can be fully utilized to further improve the heat dissipation efficiency of the radiator.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0031] In the description of the present invention, it should be understood that terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “top”, “bottom”, “inside” and “outside” indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0032] like Figure 1 and Figure 2 As shown, the present invention proposes a wind power hydraulic oil cooling device, including a radiator 100. The radiator 100 is provided with an oil inlet pipe 31 and an oil drain pipe 32. The high-temperature oil to be cooled is transported to the radiator 100 via the oil inlet pipe 31, and is discharged through the oil drain pipe 32 after being cooled by the radiator 100.

[0033] The radiator 100 includes a plurality of mutually parallel heat-conducting oil pipes 1, and two adjacent heat-conducting oil pipes 1 are connected by connecting oil pipes 3. The plurality of connecting oil pipes 3 are alternately arranged at both ends of the heat-conducting oil pipes 1, so that the plurality of heat-conducting oil pipes 1 are connected in sequence, and the plurality of heat-conducting oil pipes 1 form a longer oil circuit, thereby increasing the flow distance of the oil in the radiator 100;

[0034] The radiator 100 also includes a plurality of heat dissipation fins 2, which are sleeved on the outside of the heat transfer oil pipe 1. The heat dissipation fins 2 can form heat exchange with the outside of the heat transfer oil pipe 1, and a gap is left between two adjacent heat dissipation fins 2 for air flow to pass through for heat dissipation, so that the heat dissipation fins 2 and the heat transfer oil pipe 1 form a heat dissipation array. A fan 4 is provided on one side of the heat dissipation array to continuously transport air flow to the heat dissipation array for heat dissipation.

[0035] In this way, high-temperature oil is transported through the thermal oil pipe 1, and the heat of the oil is transferred to the heat dissipation fins 2 through the thermal oil pipe 1, thereby increasing the heat dissipation area. The airflow transported by the fan 4 takes away the heat on the surface of the thermal oil pipe 1 and the heat dissipation fins 2, thereby cooling the oil.

[0036] In a specific embodiment, the oil inlet pipe 31 and the oil drain pipe 32 are respectively connected to the two outermost thermal oil pipes 1. The high-temperature oil input by the oil inlet pipe 31 can pass through multiple thermal oil pipes 1 in sequence and then be output by the oil drain pipe 32, so that the high-temperature oil can fully exchange heat with the thermal oil pipes 1 and the heat dissipation fins 2.

[0037] Furthermore, the present invention also includes an oil pump 200 , which is connected to the oil inlet pipe 31 . The oil is pumped by the oil pump 200 to provide power for the oil so that the oil can pass through the radiator 100 .

[0038] In an optional embodiment, the oil pump 200 preferably adopts a gear pump. The gear pump is not very sensitive to dirt in the oil during operation, and even if the oil contains a certain amount of dirt, it will not seriously affect its working performance.

[0039] Furthermore, the present invention also includes a filter 300, which is connected to the oil drain pipe 32 to filter the cooled oil to keep the oil pure and avoid impurities in the oil from causing equipment wear.

[0040] Combination Figure 3 , Figure 4 and Figure 5 As shown, the interior of the heat transfer oil pipe 1 is wrapped with a cooling water pipe 11 (such as Figure 5 As shown, two adjacent cooling water pipes 11 are connected by a connecting water pipe 5, and a plurality of connecting water pipes 5 are alternately arranged at both ends of the cooling water pipe 11, so that the cooling water pipes 11 are connected in sequence (as shown in FIG. Figure 4 As shown), multiple cooling water pipes 11 form a longer cooling water circuit.

[0041] Furthermore, a mounting gap 101 is provided on one side of the heat transfer oil pipe 1, and a plurality of overflow holes 111 are provided on one side of the cooling water pipe 11 located in the mounting gap 101, and a water absorption strip 12 and a sealing strip 13 are provided in the mounting gap 101 and are distributed along the circumference of the cooling water pipe 11, and the heat transfer oil pipe 1, the water absorption strip 12 and the sealing strip 13 are wrapped together by a water absorption net 14, and the cooling water pipe 11 is configured to be able to rotate along its own axis (such as Figure 6 as shown).

[0042] In this way, when the cooling water pipe 11 rotates to the point where the overflow hole 111 corresponds to the water absorption strip 12, the overflow hole 111 can slowly drain water outwards, and the water absorption strip 12 serves as a diversion channel. The discharged water can be absorbed by the water absorption net 14 and spread to the entire water absorption net 14. Moreover, since the water absorption net 14 is wrapped around the outside of the heat transfer oil pipe 1, after the water absorption net 14 absorbs water, it can generate heat exchange with the heat transfer oil pipe 1. Since the specific heat capacity of water is greater than that of air, it can absorb more heat. At the same time, the continuous blowing of air by the fan 4 can evaporate the water on the water absorption net 14 and take away the heat, thereby improving the heat dissipation performance of the surface of the heat transfer oil pipe 1, and further improving the overall heat dissipation efficiency of the radiator 100, which can meet higher heat dissipation requirements. Moreover, compared with directly spraying cooling water, the water absorption and covering method using the water absorption net 14 can reduce water consumption.

[0043] By setting the cooling water pipe 11 for transporting cooling water to be wrapped by the thermal oil pipe 1, a heat exchange channel can be formed between the inner side of the thermal oil pipe 1 and the cooling water pipe 11, and the cooling water pipe 11 cools the inner side of the thermal oil pipe 1, thereby increasing the heat dissipation area of ​​the thermal oil pipe 1, making full use of the heat absorption performance of the cooling water, and improving the heat dissipation efficiency of the radiator 100.

[0044] When the cooling water pipe 11 rotates until the overflow hole 111 corresponds to the sealing strip 13, the overflow hole 111 can be sealed. When the heat dissipation demand is low, the overflow hole 111 does not discharge water to the outside, thereby preventing the loss of cooling water.

[0045] It should be understood that the water absorbent net 14 is made of water absorbent fibers woven together to form more weaving gaps, which increases the contact area between the water absorbent net 14 and the airflow, increases the evaporation rate of water on the water absorbent net 14, and thus improves the heat dissipation efficiency.

[0046] In an optional embodiment, the absorbent net 14 preferably uses cotton fibers, which have good water absorption performance. The water overflowing from the overflow holes 111 can be quickly transferred along the fibers and cover the entire absorbent net 14.

[0047] Combination Figure 5 As shown, the water absorption net 14 is provided with a plurality of heat conduction gaps 102 distributed along the axial direction and corresponding to the heat dissipation fins 2. The heat dissipation fins 2 are installed at the heat conduction gaps 102 so that the heat dissipation fins 2 can contact the outside of the heat conduction oil pipe 1 to form a heat transfer channel.

[0048] Combination Figure 1 and Figure 4 As shown, the present invention also includes a cooling water circulation machine 400, which is provided with an inlet pipe 51 and a return pipe 52. The inlet pipe 51 and the return pipe 52 are respectively connected to the two outermost cooling water pipes 11, so that the cooling water can pass through the multiple cooling water pipes 11 in sequence and then flow back to the cooling water circulation machine 400 through the return pipe 52.

[0049] Furthermore, the present invention also includes a water storage tank 500 and a water pump 600 , and the water storage tank 500 replenishes water to the cooling water circulation machine 400 through the water pump 600 .

[0050] In this way, when the overflow hole 111 drains water outward, the cooling water in the water tank built into the cooling water circulation machine 400 decreases, and the water storage tank 500 replenishes water to the cooling water circulation machine 400 through the water pump 600 to maintain the cooling water within a normal water volume range to meet the circulation and drainage needs.

[0051] It should be understood that a liquid level sensor is provided in the water tank built into the cooling water circulation machine 400, which can monitor the amount of cooling water in the water tank in real time. When the water level is lower than a preset value, the water pump 600 starts to transport the cooling water in the water storage tank 500 to the water tank built into the cooling water circulation machine 400 until the water level reaches the preset value.

[0052] Furthermore, the connecting water pipe 5, the water inlet pipe 51 and the water return pipe 52 are all made of rubber hoses. When the cooling water pipe 11 rotates, the soft rubber hose can produce a certain deformation to maintain the transportation of cooling water.

[0053] It should be noted that the rotation of the cooling water pipe 11 only needs to ensure that the overflow hole 111 faces the water absorption strip 12 or the sealing strip 13. Therefore, the rotation angle of the cooling water pipe 11 is small, and a rubber hose is sufficient to meet the use requirements.

[0054] Combination Figure 2 , Figure 3 and Figure 4 As shown, the driving device is arranged at one end of the cooling water pipe 11, and is used to drive multiple cooling water pipes 11 to rotate synchronously. The driving device includes a motor 6, a worm 61 and a worm wheel 62. The same end of the multiple cooling water pipes 11 is coaxially fixed with a worm wheel 62. The worm 61 is fixed at the output end of the motor 6, and the multiple worm wheels 62 are engaged with the worm 61.

[0055] In this way, the motor 6 drives the worm 61 to rotate, and the worm 61 drives the cooling water pipe 11 to rotate through the worm gear 62 , and makes the overflow hole 111 face the water absorption strip 12 or the sealing strip 13 .

[0056] Combination Figure 2 and Figure 3 As shown, the present invention also includes a support frame 7 for supporting the heat dissipation array, and connecting seats 71 corresponding to the cooling water pipe 11 are fixed to the inner walls on both sides of the support frame 7, and both ends of the cooling water pipe 11 are rotatably connected to the connecting seats 71 through bearings, so that the rotation of the cooling water pipe 11 is more stable.

[0057] In a specific embodiment, the upper and lower ends of the heat dissipation fins 2 are fixed to the inner side of the support frame 7 .

[0058] Furthermore, the motor 6 is fixed on the supporting frame 7 , and both ends of the worm 61 are rotatably connected to the supporting frame 7 .

[0059] The working principle of the present invention is as follows: the high-temperature oil is pumped by the oil pump 200 and transported to the heat-conducting oil pipe 1 through the oil inlet pipe 31, and flows through the inside of the plurality of heat-conducting oil pipes 1 in sequence, and the heat on the outer surface of the heat-conducting oil pipe 1 can be transferred to the heat-dissipating fins 2 in contact with the outer wall of the heat-conducting oil pipe 1, thereby increasing the heat dissipation area, and then the airflow transported by the fan 4 takes away the heat on the surface of the heat-conducting oil pipe 1 and the heat-dissipating fins 2, thereby cooling the oil;

[0060] When the oil temperature is too high and the airflow delivered by the fan 4 alone cannot meet the heat dissipation demand, the cooling water circulation machine 400 delivers cooling water to the cooling water pipe 11 through the water inlet pipe 51. At the same time, the motor 6 drives the worm 61 to rotate, and the worm 61 drives multiple cooling water pipes 11 to rotate synchronously through the worm gear 62, and makes the overflow hole 111 face the water absorption bar 12, and the cooling water flows out through the overflow hole 111, and the water absorption bar 12 serves as a diversion channel. The discharged water can be absorbed by the water absorption net 14 and spread to the entire water absorption net 14. Since the water absorption net 14 is wrapped around the outside of the heat transfer oil pipe 1, after the water absorption net 14 absorbs water, it can generate heat exchange with the heat transfer oil pipe 1. Since the specific heat capacity of water is larger than that of air, it can absorb more heat. At the same time, the continuous blowing of air by the fan 4 can evaporate the water on the water absorption net 14 and take away the heat, thereby improving the heat dissipation performance of the surface of the heat transfer oil pipe 1, and then improving the overall heat dissipation efficiency of the radiator 100, which can meet higher heat dissipation requirements;

[0061] By arranging the cooling water pipe 11 for conveying cooling water to be wrapped by the heat transfer oil pipe 1, a heat exchange channel can be formed between the inner side of the heat transfer oil pipe 1 and the cooling water pipe 11, and the cooling water in the cooling water pipe 11 can flow back to the cooling water circulation machine 400 via the return pipe 52 to form a circulating water circuit. Therefore, the inner side of the heat transfer oil pipe 1 can be cooled by the cooling water pipe 11, the heat dissipation area of ​​the heat transfer oil pipe 1 is increased, the heat absorption performance of the cooling water is fully utilized, and the heat dissipation efficiency of the radiator 100 is further improved.

[0062] Therefore, the heat dissipation performance of the present invention can be divided into three stages. The first stage is: only relying on the airflow delivered by the fan 4 to take away the heat on the surface of the heat transfer oil pipe 1 and the heat dissipation fin 2, so as to cool the oil. The second stage is: while maintaining the operation of the fan 4, cooling water is delivered to the cooling water pipe 11, and the cooling water pipe 11 is rotated until the overflow hole 111 corresponds to the sealing strip 13, so that the cooling water only flows in the cooling water pipe 11 and does not overflow. At this time, the airflow delivered by the fan 4 dissipates heat to the outside of the heat transfer oil pipe 1, and the cooling water pipe 11 dissipates heat to the inside of the heat transfer oil pipe 1, thereby providing High heat dissipation performance, the third stage is: while maintaining the operation of the fan 4 and the delivery of cooling water, the cooling water pipe 11 is rotated to the overflow hole 111 corresponding to the water absorption strip 12, and the cooling water flows out through the overflow hole 111 and is absorbed by the water absorption strip 12 and the water absorption net 14. After the water absorption net 14 absorbs the water, it can generate heat exchange with the thermal oil pipe 1. Since the specific heat capacity of water is greater than that of air, it can absorb more heat. At the same time, the continuous blowing of air by the fan 4 can evaporate the water on the water absorption net 14 and take away the heat, thereby further improving the heat dissipation performance of the surface of the thermal oil pipe 1.

[0063] In summary of the above embodiments: by wrapping the water absorption net 14 on the heat transfer oil pipe 1 at the gap of the heat dissipation fin 2, and providing a cooling water pipe 11 for conveying cooling water to the water absorption net 14, when the water absorption net 14 absorbs water, it can generate heat exchange with the heat transfer oil pipe 1. Since the specific heat capacity of water is larger than that of air, it can absorb more heat. At the same time, the continuous blowing of air by the fan 4 can evaporate the water on the water absorption net 14 and take away the heat, thereby improving the heat dissipation performance of the surface of the heat transfer oil pipe 1, and then improving the overall heat dissipation efficiency of the radiator 100, which can meet higher heat dissipation requirements;

[0064] By setting the cooling water pipe 11 for transporting cooling water to be wrapped by the thermal oil pipe 1, a heat exchange channel can be formed between the inner side of the thermal oil pipe 1 and the cooling water pipe 11, and the cooling water in the cooling water pipe 11 can circulate through the cooling water circulation machine 400 to form a circulating water circuit. Therefore, the cooling water pipe 11 can cool the inner side of the thermal oil pipe 1 and increase the heat dissipation area of ​​the thermal oil pipe 1. By optimizing the pipeline, the heat absorption performance of the cooling water can be fully utilized to further improve the heat dissipation efficiency of the radiator 100.
