Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of energy storage power equipment, and in particular to energy storage power equipment with a multifunctional support having efficient heat dissipation. Background Art
[0002] With the large-scale integration of renewable energy sources such as wind power and photovoltaics, energy storage systems have become critical equipment for smoothing power fluctuations and ensuring grid stability. Supercapacitors, due to their fast response (millisecond-level charge and discharge), are widely used in instantaneous compensation scenarios for wind and solar energy storage. However, outdoor supercapacitor deployment faces the following technical bottlenecks:
[0003] Traditional cooling solutions are inefficient
[0004] Air cooling: Relying on forced convection by fans, the heat dissipation efficiency drops by more than 50% in high temperature environments (>40°C), and the fan energy consumption accounts for 15%-20% of the total power consumption of the equipment.
[0005] Closed water cooling: An independent coolant circulation system is required. Complex pipes are prone to blockage (annual failure rate 12%), and coolant leakage can cause capacitor short circuit.
[0006] Poor environmental adaptability
[0007] Rainwater erosion: Water easily seeps into the joints of the outdoor equipment casing, causing internal circuit boards to become damp.
[0008] Dust accumulation: In sandy areas, the dust on the heat sink surface increases in thickness by 1mm, and the heat dissipation efficiency decreases by 30%.
[0009] Water dependence and waste
[0010] Traditional water cooling systems require continuous water supply (average water consumption of 3-5m 3 / MWh), which is difficult to promote in arid areas.
[0011] Direct discharge of cooling water causes waste of resources, and wastewater containing preservatives pollutes the environment.
[0012] High maintenance costs
[0013] Repairing the built-in heat dissipation structure requires disassembling the equipment, which increases the maintenance time by 2-3 times.
[0014] These drawbacks severely restrict the large-scale application of supercapacitor energy storage in outdoor environments. Therefore, a self-circulating, maintenance-free, and highly environmentally adaptable heat dissipation support system is urgently needed. Summary of the Invention
[0015] In view of the deficiencies of the prior art, the present invention provides an energy storage power device with multifunctional support and efficient heat dissipation, which solves the above-mentioned problems.
[0016] To achieve the above objectives, the present invention is implemented through the following technical solutions: a multifunctional energy storage power device with efficient heat dissipation, comprising an energy storage capacitor placed in the open air for compensating for instantaneous power fluctuations in a wind farm, a support base fixed below the energy storage capacitor for supporting the energy storage capacitor, the inner cavity of the energy storage capacitor having a rectangular heat conduction groove extending vertically therethrough, the inner cavity of the support base having a water storage groove connected to the rectangular heat conduction groove, and a water storage mechanism provided on the top of the energy storage capacitor;
[0017] The inner cavity of the rectangular heat conduction groove is fixedly connected with a lifting cylinder, and the inner cavity of the lifting cylinder is slidably sealed with a piston ring driven by a cylinder. The bottom of the lifting cylinder is connected to a one-way water inlet pipe, and both sides of the lifting cylinder are connected to a one-way water outlet pipe. The end of the one-way water inlet pipe passes through and extends to the inner cavity of the water storage tank. The ends of the two one-way water outlet pipes are fixedly connected with an atomizing nozzle facing the top of the rectangular heat conduction groove. When in use, in order to smooth out wind and light fluctuations, energy storage capacitors are used to quickly compensate for instantaneous power fluctuations in photovoltaic / wind farms and reduce the impact on the power grid. They are generally packaged in standardized cabinets or containers and then placed in the open air. When the outside temperature is too high on hot days, due to the low temperature difference between the inside and outside, the high temperature generated during internal operation cannot be dissipated smoothly, which will reduce the service life. At this time, rainwater on rainy days is filtered through the filter. Then it enters the holding box and then enters the water storage tank through the rectangular heat conduction groove for storage. Outdoor rainwater can be used to dissipate the high temperature during work. When it is hot, the high temperature is transferred to the rectangular heat conduction groove. At this time, the cylinder inside the lifting cylinder is started to drive the piston ring to move up and down to form positive and negative pressure. The water in the water storage tank is pumped into the one-way water inlet pipe, and then pressurized and sprayed out through the one-way water outlet pipe, and then sprayed toward the inner wall of the rectangular heat conduction groove through the atomizing nozzle. At this time, the spoiler is rotated to form an air flow, and the water vapor generated by the heat below is discharged upward, and contacts the stainless steel film of the rectangular heat conduction groove. Under the action of evaporation, the heat contained inside is quickly taken away, and the principle of evaporation heat absorption can be used to continuously cool down, and there is no need to worry about the water circulation pipe passing through the inside of the energy storage capacitor and causing the risk of water leakage.
[0018] As a further solution of the present invention: the inner wall of the rectangular heat-conducting groove is covered with a stainless steel film that contacts the heat-conducting component of the energy storage capacitor, which is covered while conducting heat to prevent external water from entering.
[0019] As a further solution of the present invention: the inner cavity of the rectangular heat-conducting groove located above the lifting cylinder is rotatably connected to a spoiler driven by a motor. The rotation of the spoiler forms an airflow, which guides the water vapor generated by the heat below upward and contacts the stainless steel film of the rectangular heat-conducting groove, and quickly takes away the heat contained inside under the action of evaporation.
[0020] As a further solution of the present invention: a filter ball is fixedly connected to the end of the one-way water inlet pipe, and the extracted water is filtered by the filter ball to prevent large particles of impurities from entering the lifting cylinder and affecting normal work.
[0021] As a further solution of the present invention: the side of the support base is connected to an overflow pipe connected to the water tank. The setting of the overflow pipe can prevent excessive rainwater from accumulating inside the water tank, and the overflow pipe is extended outside the support base to direct the water to a distant place.
[0022] As a further solution of the present invention: it also includes a water tank connected to the water storage tank in the inner cavity of the support base through a constant pressure pipe. In addition to being supplied by rainwater, it is also supplied through the water tank. When the water volume inside the water tank is insufficient, under atmospheric pressure, the water tank and the water storage tank always maintain a uniform water level to ensure long-term cooling.
[0023] As a further solution of the present invention: the water storage mechanism includes a first baffle fixed on the top of the energy storage capacitor, the top of the first baffle is fixedly connected to a holding box, the bottom of the holding box is communicated with the rectangular heat conduction groove, the top of the holding box is fixedly connected to a filter screen, and both sides of the filter screen are provided with a slope inclined downward from the middle toward the outside, so that when rainwater can be filtered, it can be flushed by rainwater to wash away dirt, and the rainwater enters the holding box after being filtered by the filter screen, and then enters the water storage tank through the rectangular heat conduction groove for storage. The outdoor rainwater can be used to dissipate the high temperature during operation.
[0024] As a further solution of the present invention: a second baffle is fixedly connected to the side of the support base to block rainwater and prevent it from directly eroding the foundation near the support base.
[0025] Compared with the prior art, the present invention has the following beneficial effects:
[0026] 1. Efficient natural heat dissipation: Using open-air rainwater as a cooling medium, heat is dissipated through a dual mechanism of atomization spray and evaporation heat absorption, significantly reducing the operating temperature of the energy storage capacitor (the efficiency is increased by more than 40% compared to traditional air cooling). The one-way water inlet pipe draws water from the water storage tank, and then sprays it out under pressure through the one-way water outlet pipe. It is then sprayed toward the inner wall of the rectangular heat conduction groove through the atomizing nozzle. At this time, the spoiler rotates to form an air flow, which guides the water vapor generated by the heat below upward and contacts the stainless steel membrane of the rectangular heat conduction groove. Under the action of evaporation, the heat contained inside is quickly taken away. The principle of evaporation heat absorption can be used to continuously cool down the capacitor, and there is no need to worry about the risk of water leakage caused by the water circulation pipe passing through the energy storage capacitor.
[0027] 2. No water leakage risk: The external water circulation system (water storage tank, lifting cylinder, atomizing nozzle) is used to prevent the cooling pipe from penetrating the interior of the capacitor, eliminating water leakage and causing equipment short circuit;
[0028] 3. Intelligent temperature control linkage: The cylinder drives the piston ring to achieve on-demand water pumping and spraying, and the spoiler actively guides steam to achieve dynamic matching of heat dissipation intensity and temperature fluctuations;
[0029] 4. Enhanced environmental adaptability: Rainwater collection and filtration system (filter screen, filter ball) adapts to dusty and rainy environments;
[0030] 5. The water reservoir and overflow pipe design ensures water balance and foundation protection in extreme weather conditions; low maintenance cost: the stainless steel film covers the heat conduction groove to prevent corrosion, and the open structure facilitates cleaning and maintenance.

[0037] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.
[0038] See also Figure 1-4The present invention provides a technical solution: a multifunctional energy storage power device with efficient heat dissipation, comprising an energy storage capacitor 1 placed in the open air for compensating for instantaneous power fluctuations in a wind farm, a support base 2 fixed below the energy storage capacitor 1 for supporting the energy storage capacitor 1, a rectangular heat conduction groove 4 extending vertically through the inner cavity of the energy storage capacitor 1, a water storage groove 3 communicating with the rectangular heat conduction groove 4, and a water storage mechanism provided on the top of the energy storage capacitor 1;
[0039] The inner cavity of the rectangular heat conduction groove 4 is fixedly connected with a lifting cylinder 6, and the inner cavity of the lifting cylinder 6 is slidingly sealed with a piston ring 8 driven by a cylinder 7. The bottom of the lifting cylinder 6 is connected with a one-way water inlet pipe 11, and both sides of the lifting cylinder 6 are connected with a one-way water outlet pipe 9. The end of the one-way water inlet pipe 11 passes through and extends to the inner cavity of the water storage tank 3. The ends of the two one-way water outlet pipes 9 are fixedly connected with an atomizing nozzle 10 facing the top of the rectangular heat conduction groove 4. When in use, in order to smooth out wind and light fluctuations, the energy storage capacitor 1 is used to quickly compensate for instantaneous power fluctuations in photovoltaic / wind farms and reduce the impact on the power grid. It is generally packaged in a standardized cabinet or container and then placed in the open air. When the outside temperature is too high on hot days, due to the low temperature difference between the inside and outside, the high temperature generated during internal work cannot be smoothly dissipated, which will reduce the service life. At this time, rainwater on rainy days is filtered through the filter 17 and enters the storage tank The heat is then directed to the heat exchanger 4 by means of the air filter 22. The heat is then directed to the heat exchanger 4 by means of the air filter 23. The heat is then directed to the heat exchanger 4 by means of the air filter 24. The heat is then directed to the heat exchanger 4 by means of the air filter 25.

[0041] The inner cavity of the rectangular heat-conducting groove 4 located above the lifting cylinder 6 is rotatably connected to a spoiler 20 driven by a motor. The rotation of the spoiler 20 forms an airflow, which guides the water vapor generated by the heat below upward and contacts the stainless steel film 5 of the rectangular heat-conducting groove 4, and quickly takes away the heat contained inside under the action of evaporation.
[0042] A filter ball 12 is fixedly connected to the end of the one-way water inlet pipe 11, and the extracted water is filtered by the filter ball 12 to prevent large particles of impurities from entering the lifting cylinder 6 and affecting normal operation.
[0043] The side of the support base 2 is connected to an overflow pipe 14 connected to the water tank 3. The setting of the overflow pipe 14 prevents excessive rainwater from being stored in the water tank 3, and the overflow pipe 14 extends outside the support base 2 to guide the water to a distant place.
[0044] It also includes a water tank 15 connected to the water tank 3 in the inner cavity of the support base 2 through a constant pressure pipe 13. In addition to being supplied by rainwater, it is also attacked through the water tank 15. When the water volume inside the water tank 15 is insufficient, under atmospheric pressure, the water tank 15 and the water tank 3 always maintain a uniform water level to ensure long-term cooling.
[0045] The water storage mechanism includes a first baffle 18 fixed to the top of the energy storage capacitor 1, and the top of the first baffle 18 is fixedly connected to a receiving box 21.

Both sides of the filter screen 17 are provided with a slope 16 that tilts downward from the middle toward the outside. When the rainwater can be filtered, the rainwater can be used to flush the dirt and wash it down. After being filtered by the filter screen 17, the rainwater enters the receiving box 21 and then enters the water storage tank 3 through the rectangular heat conduction groove 4 for storage. The outdoor rainwater can be used to dissipate the high temperature during operation.
[0046] A second baffle 18 is fixedly connected to the side of the support base 2 to block rainwater and prevent it from directly eroding the foundation near the support base 2.
[0047] Dual-mode cooling mechanism:
[0048] Atomization spray cooling: The cylinder 7 drives the piston ring 8 to form a high-pressure water flow. The atomization nozzle 10 controls the water particle diameter to 20-50μm, increasing the contact area with the heat conduction groove 4, and the instantaneous heat absorption efficiency reaches 3.2kW / m 2 2.5 times higher than traditional spraying.
[0049] Steam evaporation enhancement: The spoiler 20 forces the airflow to make the water vapor rise at a rate of 1.5m / s. After contacting the stainless steel film 5, the utilization rate of the evaporation latent heat exceeds 85%, and the overall heat dissipation power consumption is reduced by 60%.
[0050] Measured data: At an ambient temperature of 45°C and full capacitor load, the internal temperature is stabilized at 40±2°C. The traditional solution is 55-60°C, and the equipment life is extended to 8 years, while the national standard requires 5 years.
