Description

Technical Field

[0001] The present invention relates to a heat dissipation system device for an energy storage device, in particular to an energy-saving heat dissipation system for a flywheel energy storage device, belonging to the field of heat dissipation for flywheel energy storage devices. Background Art

[0002] Under normal operating conditions, the main heat dissipation components of the flywheel device are the converter and the stator of the flywheel motor. The water cooling system can take away part of the heat of the converter and the heat of the flywheel motor stator; the heat dissipated by the reactor of the converter cabinet is taken away by the air cooling system and dissipated into the surrounding air.

[0003] Under stopped conditions, the main heat dissipation component of the flywheel device is the discharge resistor 1. Taking a 37MJ flywheel as an example, when the flywheel stops within 5 minutes, a large amount of heat is instantly dissipated into the surrounding air. The average heat dissipation power within 5 minutes is 123.3kW. If multiple flywheel devices in the computer room are shut down at the same time, the heat dissipation will be huge, which will cause the instantaneous temperature in the computer room to soar, posing a safety hazard.

[0004] Therefore, there is an urgent need to improve the heat dissipation system of the energy-saving flywheel energy storage device to solve the above-mentioned problems. Summary of the Invention

The generated heat is transferred to the insulating ceramic shell that wraps the discharge resistor. The heat is conducted to the thermal bridge connected to it through the insulating ceramic shell. The thermal bridge is connected to a three-way ball valve, and the three-way ball valve controls the flow direction of heat. Under normal circumstances, the heat flows to the heat dissipation tower through the three-way ball valve. The heat dissipation tower can effectively receive and dissipate the heat transferred from the thermal bridge, reduce the temperature of the computer room caused by the heat generated by the discharge resistor, ensure that the ambient temperature of the computer room is suitable for the normal operation of the equipment, and ensure the stable operating environment of the flywheel energy storage device. When there is a heat demand, the three-way ball valve is switched to allow the heat to flow to the waste heat recovery component.

[0018] The present invention has at least the following beneficial effects:

[0019] 1. When the flywheel energy storage device is shut down, the bleeder resistor on one side of it starts working, instantly converting the electrical energy stored in the device into thermal energy. The generated heat is transferred to the insulating ceramic shell that wraps the bleeder resistor. The heat is then transferred to the thermal bridge connected to it through the insulating ceramic shell. The thermal bridge is connected to a three-way ball valve, which controls the flow of heat. Under normal circumstances, the heat flows to the heat dissipation tower through the three-way ball valve. The heat dissipation tower can effectively receive and dissipate the heat transferred from the thermal bridge, reducing the temperature of the computer room caused by the heating of the bleeder resistor, ensuring that the ambient temperature of the computer room is suitable for normal operation of the equipment, and ensuring a stable operating environment for the flywheel energy storage device.

[0020] 2. Since the entire system will be affected by temperature changes during operation, the pipeline will expand and contract due to heat and cold. The bellows compensator can effectively absorb the change in pipeline length caused by temperature changes through its own expansion and contraction, and prevent the pipeline from being damaged due to excessive thermal stress. When the pipeline system is running, vibration may occur. The bellows compensator can buffer and absorb these vibration energies to a certain extent, reduce the impact of vibration on the pipeline connection parts, and reduce the generation of noise.

[0021] 3. The air inlet of the heat dissipation tower provides an entry channel for cold air, which will naturally rise under the action of the chimney effect. The air outlet discharges the air with increased temperature after heat exchange in the heat dissipation tower to ensure the continuity of the heat dissipation process. The nickel-based metal plate increases the heat dissipation area and strengthens the heat exchange process. The nickel-based metal plate has good thermal conductivity and can quickly absorb and conduct heat, so that the air in contact with it can absorb heat more effectively and improve the heat dissipation efficiency. The conical draft shield reduces the interference of external lateral wind force on the natural convection in the heat dissipation tower, stabilizes the air flow in the tower, and ensures the heat dissipation effect.

DETAILED DESCRIPTION

[0032] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0033] like Figures 1-8As shown, the energy-saving flywheel energy storage device heat dissipation system provided in this embodiment includes a discharge resistor 1, a heat dissipation tower 2 and a waste heat recovery component 3. The discharge resistor 1 is fixed on one side of the flywheel energy storage device. When the flywheel energy storage device is shut down, the discharge resistor 1 is used to instantly release the stored electrical energy and convert it into heat energy to avoid safety hazards caused by residual electrical energy in the device or affect subsequent equipment maintenance and operation. The outer wall of the discharge resistor 1 is fixedly connected to an insulating ceramic shell 4. On the one hand, the insulating ceramic shell 4 plays an electrical insulation role for the discharge resistor 1 to prevent the operator from getting an electric shock and ensure personal safety. On the other hand, the radiation heat dissipation coating coated on its surface can enhance the infrared radiation heat dissipation capacity and assist the discharge resistor 1 in heat dissipation. A thermal bridge 5 is connected to one side of the insulating ceramic shell 4, and the other end of the thermal bridge 5 extends to the outdoors. The thermal bridge 5 is made of high thermal conductivity material, such as copper or graphene composite material, and transfers the heat generated by the discharge resistor 1 to the outdoor heat dissipation tower 2 or the waste heat recovery component 3 to achieve directional heat transfer.

[0034] The heat dissipation tower 2 and the waste heat recovery component 3 are respectively located on both sides of the end of the heat conduction bridge 5. The heat dissipation tower 2 and the waste heat recovery component 3 are commonly connected to a three-way ball valve 6. The other end of the three-way ball valve 6 is connected to the heat conduction bridge 5. The heat dissipation tower 2 is located outdoors, receives heat transferred from the heat conduction bridge 5, and dissipates the heat into the atmosphere, effectively reducing the temperature in the computer room caused by the heating of the discharge resistor 1, ensuring that the ambient temperature of the computer room is suitable for the normal operation of the equipment. When there is a heat demand, the waste heat recovery component 3 changes the heat flow direction through the three-way ball valve 6, and recovers and reuses the waste heat received from the discharge resistor 1 on the heat conduction bridge 5;

[0035] Further, such as Figures 1-8 As shown, multiple vacuum-sealed phase-change heat pipes 21 are embedded in the interior of the thermal bridge 5 along the axial direction. There are three phase-change heat pipes 21. The vacuum-sealed phase-change heat pipes 21 play a core role in accelerating heat conduction inside the thermal bridge 5. The evaporation section of the phase-change heat pipe 21 is close to the discharge resistor 1. When the heat generated by the discharge resistor 1 is transferred to the thermal bridge 5, the working fluid in the evaporation section of the heat pipe absorbs heat and evaporates. The steam flows to the condensation section under the action of the pressure difference, and is liquefied by the cold in the condensation section, releasing latent heat, and efficiently transferring heat from one end of the thermal bridge 5 to the other end, thereby greatly improving the overall heat transfer efficiency of the thermal bridge 5. The liquefied working fluid then flows back to the evaporation section.

[0036] Among them, Figures 1-8As shown, the insulating ceramic shell 4 is fixed to one side of the thermal bridge 5 by multiple screws. A copper connecting piece 31 is provided inside the insulating ceramic shell 4. The copper connecting piece 31 is in close contact with the bleeder resistor 1. The insulating ceramic shell 4 is firmly fixed to one side of the thermal bridge 5 by screws to ensure a tight connection between the two and maintain a stable mechanical connection and heat transfer path. The screw connection method is simple and reliable, easy to install and disassemble, and is conducive to the assembly, maintenance and repair of the equipment. The copper connecting piece 31 has good thermal conductivity and a high thermal conductivity coefficient, which can efficiently and quickly transfer the heat generated by the bleeder resistor 1 to the insulating ceramic shell 4.

[0037] Among them, Figures 1-8 As shown, the side of the heat dissipation tower 2 close to the three-way ball valve 6 is fixedly connected with a heat dissipation pipe 41, and the other end of the heat dissipation pipe 41 is fixedly connected with a bellows compensator 42. The heat dissipation pipe 41 is a component connecting the heat dissipation tower 2 and the bellows compensator 42, and undertakes the important task of transferring the heat transferred from the three-way ball valve 6 to the heat dissipation tower 2. The side of the bellows compensator 42 close to the three-way ball valve 6 is fixedly connected with a flange 1 43, and the flange 1 43 and one end of the three-way ball valve 6 conflict with each other. Since the entire system will be affected by temperature changes during operation, the pipeline will Thermal expansion and contraction occur, and the bellows compensator 42 can effectively absorb the change in pipe length caused by temperature changes through its own expansion and contraction, preventing the pipe from being damaged due to excessive thermal stress. When the pipe system is in operation, vibration may occur, and the bellows compensator 42 can buffer and absorb the vibration energy to a certain extent, reducing the impact of vibration on the pipe connection parts and reducing noise generation. The two sides of the flange 1 43 are tightly connected to the bellows compensator 42 and the three-way ball valve 6 respectively, which can not only transfer heat to the inside of the pipe, but also transfer heat through itself;

[0038] Further, such as Figures 1-8 As shown, an air inlet 51 is provided at the bottom of the heat dissipation tower 2, and an air outlet 52 is provided at the upper end of the heat dissipation tower 2. The air inlet 51 provides an entry channel for cold air, which will naturally rise under the action of the chimney effect, and the air outlet 52 discharges the air whose temperature has increased after heat exchange in the heat dissipation tower 2, thereby ensuring the continuity of the heat dissipation process. The interior of the heat dissipation tower 2 is fixedly connected with multiple nickel-based metal plates 53. The nickel-based metal plates 53 increase the heat dissipation area and strengthen the heat exchange process. The nickel-based metal plates 53 have good thermal conductivity and can quickly absorb and conduct heat, so that the air in contact with them can absorb heat more effectively, thereby improving the heat dissipation efficiency. A conical flow shield 54 is fixedly connected to the upper end of the heat dissipation tower 2. The conical flow shield 54 reduces the interference of external lateral wind force on the natural convection in the heat dissipation tower 2, stabilizes the air flow in the tower, and ensures the heat dissipation effect. When there is wind outside, the conical flow shield 54 can change the wind direction, so that the wind flows along the surface of the cover, avoiding direct blowing into the air outlet 52 to affect the discharge of hot air.

[0039] Among them, Figures 1-8 As shown, the waste heat recovery component 3 includes a heat exchange pipe 61, a circulation pipe 62 and a circulation pump 63. The heat exchange pipe 61 is made of high thermal conductivity material and has good thermal conductivity. It can efficiently obtain the waste heat transferred from the thermal bridge 5 from the three-way ball valve 6 and transfer the heat to the medium flowing in the circulation pipe 62, thereby realizing the transfer of waste heat from the heat dissipation system to the external heat utilization system. The circulation pipe 62 provides a circulation path for the heat exchange medium, so that the medium can continuously flow on the outer wall of one end of the heat exchange pipe 61, be transported to the external heat utilization system through the circulation pipe 62 to release heat, and then return to the heat exchange pipe 61 to continue absorbing waste heat, forming a continuous heat transfer cycle. The circulation pump 63 provides power for the flow of the medium in the circulation pipe 62. One end of the heat exchange pipe 61 is fixedly connected to a flange 2 64, which is fixedly connected to one end of the three-way ball valve 6. One end of the heat exchange pipe 61 is tightly connected to the three-way ball valve 6 through the flange 2 64, ensuring that waste heat can smoothly enter the heat exchange pipe 61. The other end of the heat exchange pipe 61 extends into the interior of the circulation pipe 62. The two ends of the circulation pipe 62 are respectively connected to the water inlet and the water outlet of the circulation pump 63. An external heat utilization system can be connected to any point on the circulation pipe between the water inlet of the circulation pump 63 and the heat exchange pipe 61. The design of the other end of the heat exchange pipe 61 extending into the interior of the circulation pipe 62 ensures that the heat exchange pipe 61 is fully in contact with the medium in the circulation pipe 62, thereby increasing the heat exchange area, thereby effectively transferring the waste heat to the medium and realizing the recovery and utilization of heat energy.

[0040] Among them, Figures 1-8 As shown, the outer wall of the operating rod of the three-way ball valve 6 is fixedly connected to a ratchet gear 71, and a ratchet plate 72 is provided on one side of the ratchet gear 71 that meshes with the ratchet gear 71. The ratchet plate 72 cooperates with the ratchet gear 71 to realize the transmission of motion, and converts its own linear motion into a unidirectional rotation of the ratchet gear 71, thereby controlling the steering inside the three-way ball valve 6 to change the direction of heat transfer. Limit blocks 73 are provided at both ends of the ratchet plate 72. The limit blocks 73 limit the range of motion of the ratchet plate 72 to prevent it from being out of engagement with the ratchet gear 71 during movement. A push plate 74 is fixedly connected to one side of the ratchet plate 72, and the push plate 74 provides driving force for the movement of the ratchet plate 72.

[0041] Further, such as Figures 1-8As shown, the outer wall of one end of the three-way ball valve 6 close to the flange 1 43 is fixedly connected to a fixing ring 81, and a plurality of interference rods 82 are slidably connected inside the fixing ring 81. The fixing ring 81 provides a slidable track for the interference rods 82, ensuring that the plurality of interference rods 82 can make linear motion along a fixed direction. One end of the plurality of interference rods 82 is fixedly connected to the flange 1 43, and the interference rods 82 achieve a tight connection or separation between the flange 1 43 and the three-way ball valve 6 by sliding within the fixing ring 81. The other ends of the plurality of interference rods 82 are commonly fixedly connected to a interference ring 83, and the interference ring 83 is slidably connected to the outer wall of the three-way ball valve 6. The interference ring 83 fixes the other ends of the plurality of interference rods 82 together, ensuring that the plurality of interference rods 82 can work together.

[0042] Further, if Figures 1-8 As shown, the outer walls of the multiple resistance rods 82 are all sleeved with resistance springs 91, and the two ends of the resistance springs 91 are respectively connected to the fixing ring 81 and the resistance ring 83. The resistance springs 91 are usually in a compressed state during installation, and will exert a certain elastic force on the fixing ring 81 and the resistance ring 83, thereby causing the resistance rods 82 to generate a continuous pre-tightening force on the flange 1 43, ensuring that the flange 1 43 fits tightly with the three-way ball valve 6, enhancing the sealing of the connection part, and facilitating automatic reset after the flange 1 43 is disconnected from the three-way ball valve 6 through the multiple resistance springs 91.

[0043] Among them, Figures 1-8 As shown, both upper and lower sides of the three-way ball valve 6 are slidably connected with a contact plate 101. There are two contact plates 101, which are respectively located on the upper and lower sides of the three-way ball valve 6. The contact plates 101 and the contact ring 83 contact each other, and the side of the contact is a curved surface. By making the contact plate 101 move linearly, the contact ring 83 is pushed to slide along the outer wall of the three-way ball valve 6, thereby driving the contact rod 82, flange 43 and related components connected thereto to move. One side of the multiple contact plates 101 is fixed to the push plate 74. A fixed connection is provided on one side of the push plate 74, and an electric telescopic rod 102 is provided. The output end of the electric telescopic rod 102 is connected to the push plate 74. When the waste heat is recovered, the electric telescopic rod 102 provides power to the push plate 74 through its telescopic movement, thereby driving the two contact plates 101 and the ratchet plate 72 to move, rotating the three-way ball valve 6, so that the heat flows to the waste heat recovery component 3, and at the same time disconnecting the connection between the flange 1 43 and the three-way ball valve 6, thereby avoiding heat waste and improving the heat recovery rate.

[0044] like Figures 1-8As shown, the principle of an energy-saving flywheel energy storage device heat dissipation system provided by this embodiment is as follows: during the normal operation of the flywheel energy storage device, electrical energy is stored in the flywheel system. When the flywheel energy storage device enters the shutdown condition, the discharge resistor 1 starts to work, and the discharge resistor 1 instantly releases the electrical energy stored in the device and converts it into heat energy. The heat generated by the discharge resistor 1 is first transferred to the insulating ceramic shell 4 through the copper connecting piece 31 in close contact with it. The heat is transferred to the thermal bridge 5 connected to it through the insulating ceramic shell 4. The multiple phase change heat pipes 21 inside the thermal bridge 5 act to reduce the heat and transfer it to the end of the outdoor thermal bridge 5. When in the heat dissipation mode, the heat is transferred to the three-way ball valve 6 through the thermal bridge 5, and then sent to the heat dissipation pipe 41 through the bellows compensator 42. The heat is transferred to the heat dissipation tower 2 through the heat dissipation pipe 41. The air inlet 51 at the bottom of the heat dissipation tower 2 draws in cold air, and the nickel-based metal plate 53 inside quickly absorbs and conducts heat to the air. The hot air is The air rises under the chimney effect and is discharged from the top air outlet 52. When there is heat demand outside and waste heat recovery is required, the electric telescopic rod 102 is started to provide power for the pushing plate 74. The pushing plate 74 drives the two contact plates 101 and the ratchet plate 72 fixed thereto to move. The linear motion of the contact plate 101 pushes the contact ring 83 to slide along the three-way ball valve 6 through the curved surface. The contact ring 83 drives multiple contact rods 82 to slide in the fixed ring 81, so that the flange 43 connected to one end of the contact rod 82 is separated from the three-way ball valve 6. The linear motion of the ratchet plate 72 is converted into a unidirectional rotation of the ratchet gear 71, which in turn drives the three-way ball valve 6 to rotate, changing the channel direction of the three-way ball valve 6. The heat is transferred to the heat exchange pipe 61 through the three-way ball valve 6. The heat exchange pipe 61 obtains the waste heat and transfers the heat to the medium flowing in the circulation pipe 62. The circulation pump 63 provides power for the flow of the medium in the circulation pipe 62, thereby achieving the recovery and reuse of the waste heat.
