Description

[0002] With the large-scale access of renewable energy and the rapid development of smart grid technology, energy storage systems play a key role in power peak shaving, emergency power supply and microgrid operation. The coordinated scheduling of multiple types of energy storage devices (such as battery energy storage, supercapacitors, flywheel energy storage, etc.) requires higher thermal stability for management devices. Due to the difference and intermittent characteristics of the heat generated by different energy storage units during charging and discharging, traditional cooling schemes often use fixed air ducts or uniform cooling layouts, which are difficult to achieve dynamic and precise temperature control, leading to increased risk of local overheating and seriously affecting equipment life and system safety.

[0003] In the prior art, the cooling system of the energy storage management device is designed with a single fan and evenly distributed cooling holes, with fixed air supply direction and limited coverage. When the local temperature of a circuit board increases due to sudden load changes, the traditional cooling structure cannot quickly adjust the air supply path, and multiple redundant fans often need to be started for global cooling, causing energy waste and noise accumulation. In addition, although some schemes use zoned temperature control to control the temperature of each region with independent fans, they have problems such as large equipment size and airflow interference.

[0029] EMBODIMENT

[0030] REFERENCE Figures 1-4 For one embodiment of the present application, a coordination management device for various energy storage scheduling is provided, comprising:

[0031] The adjustable air supply unit 100 comprises a shell 101, the inside of the shell 101 is provided with a cross-shaped metal partition plate 102, the cross-shaped metal partition plate 102 divides the inside of the shell 101 into four independent heat dissipation areas, a central air cavity 103 is arranged at the intersection of the cross-shaped metal partition plate 102, a central air inlet 104 is arranged at the top of the shell 101 and communicates with the central air cavity 103, four partitioned air outlet pipes 105 are arranged around the central air cavity 103, the air outlet ends of the four partitioned air outlet pipes 105 extend into the four independent heat dissipation areas respectively, an axial flow fan 106 is arranged in the central air cavity 103, the bottom of the axial flow fan 106 is fixedly connected with a mounting flange 107, the bottom of the mounting flange 107 is rotatably connected with the bottom of the inner wall of the central air cavity 103, and the adjustable air supply unit 100 further comprises a driving assembly for driving the axial flow fan 106 to rotate.

[0032] The driving assembly comprises a stepping motor 108 and a driving gear 109 mounted on the output end of the stepping motor 108, a driven gear ring 110 is sleeved on the outer edge of the mounting flange 107, the driven gear ring 110 is engaged with the driving gear 109, the stepping motor 108 is fixedly installed on the top of the shell 101, the driving gear 109 is rotatably installed in the central air cavity 103, and the output end of the stepping motor 108 penetrates through the top wall of the shell 101 and extends into the central air cavity 103.

[0033] Four air outlets 111 are arranged on the shell 101, and the positions of the four air outlets 111 correspond to the four heat dissipation areas one by one.

[0034] A guide vane 112 is arranged in the partitioned air outlet pipe 105, one end of the guide vane 112 is fixedly connected with a rotating shaft 113, the rotating shaft 113 is fixedly connected to the bottom end of the inner side wall of the partitioned air outlet pipe 105, an electromagnet 114 is fixedly connected to the bottom end of the guide vane 112 in the partitioned air outlet pipe 105, a limiting protrusion 115 is fixedly connected in the partitioned air outlet pipe 105, and the limiting protrusion 115 is used for limiting the maximum rotation angle of the guide vane 112 to 90°.

[0035] A dustproof filter screen 116 is embedded in the central air inlet 104, and a one-way flap 117 is arranged at the air outlet of the partitioned air outlet pipe 105, the one-way flap 117 is hingedly connected to the air outlet of the air outlet pipe and is opened only when the air flows outward. The one-way flap is hingedly connected to the air outlet of the partitioned air outlet pipe, and is made of light alloy, which can be rotated to open under the pressure of the air flow, and is automatically closed due to gravity when the air flow stops, thereby effectively preventing the backflow of external air.

[0036] The control unit 200 comprises a temperature sensor 201 attached to the circuit board of each heat dissipation area and an MCU controller 202, and the temperature sensor 201 is electrically connected with the MCU controller.

[0037] MCU controller 202 is electrically connected with the stepper motor 108 and the electromagnet 114. When the temperature sensor 201 of a certain heat dissipation area detects a value exceeding the set threshold, the MCU controller 202 sends a power-on signal to the electromagnet 114 of the corresponding partition and sends a driving signal to the stepper motor 108, so that the axial flow fan 106 rotates to the direction of the heat dissipation area.

[0038] Workflow

[0039] Temperature monitoring phase:

[0040] Temperature sensors 201 are attached to the circuit boards of the four independent heat dissipation areas. Each sensor collects real-time temperature data of the corresponding area and transmits the data to the MCU controller 202 through electrical signals.

[0041] The MCU controller 202 has a pre-set temperature threshold (e.g. 60°C). When the temperature sensor 201 of a certain heat dissipation area (take area A as an example) detects a value exceeding the threshold, the directional heat dissipation control logic is triggered.

[0042] Directional air supply starts:

[0043] The MCU controller 202 sends a power-on instruction to the electromagnet 114 in the partition exhaust pipe 105 except for area A.

[0044] The electromagnet 114 generates a magnetic force after being powered on, attracting the bottom end of the flow guide plate 112 to move towards the electromagnet 114, causing the flow guide plate 112 to rotate around the rotating shaft 113. After rotating 90°, the flow guide plate 112 is blocked and fixed by the limiting protrusion 115 inside the partition exhaust pipe 105, sealing the partition exhaust pipe 105, while the unpowered partition exhaust pipe 105 is in a ventilation state.

[0045] At the same time, the MCU controller 202 sends a pulse driving signal to the stepper motor 108, and the output end of the stepper motor 108 drives the driving gear 109 to rotate, driving the driven gear ring 110 connected to the outer edge of the mounting flange 107 through gear meshing, causing the axial flow fan 106 and the mounting flange 107 to rotate around the bottom of the central air chamber 103, until the outlet direction of the axial flow fan 106 aligns with the inlet of the partition exhaust pipe 105 of area A.

[0046] Air distribution and heat dissipation:

[0047] The axial flow fan 106 starts, and external cold air is sucked into the central air chamber 103 through the central air inlet 104 (filtered by the dust filter 116). The cold air is pressurized by the axial flow fan 106 and flows at high speed along the open flow guide channel in the partition exhaust pipe 105 of area A, directly delivering to the surface of the circuit board in area A for forced convection heat dissipation.

[0048] The cold air current is forced to radiate the circuit board of the area A, and is discharged through the exhaust port 111 on the side of the shell 101; in this process, the one-way flap 117 at the outlet of the partitioned exhaust pipe 105 rotates to open under the air pressure of the hinge, ensuring that the air current flows outward in one direction; when the air current stops, the one-way flap 117 is automatically closed due to gravity.

[0049] Reset and cycle control:

[0050] When the temperature of the area A drops below the threshold value, the MCU controller 202 cuts off the power supply of the electromagnet 114, the flow guide piece 112 is reset to open and close, and the step motor 108 drives the fan to return to the initial angle (or waits for the next high-temperature area instruction).

[0051] If multiple areas are simultaneously overheated, the MCU controller 202 sequentially schedules the fan rotation and opens the corresponding flow guide piece 112 according to the priority (such as temperature from high to low).

[0052] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application. They should be included in the scope of the claims of the present application.
