Description

Technical Field

[0001] This utility model relates to a heat dissipation device for a photovoltaic energy storage station, specifically a heat dissipation device for a photovoltaic energy storage station based on a thermal management system. Background Technology

[0002] A photovoltaic (PV) energy storage station is a power generation system that uses photovoltaic modules to convert solar energy into electrical energy and stores excess energy in energy storage batteries for release when needed. Key components in a PV energy storage station, such as photovoltaic panels, inverters, and battery packs, generate a significant amount of heat during operation; failure to dissipate this heat in a timely manner can affect the normal operation of the equipment.

[0003] Photovoltaic panels often use natural cooling and water cooling devices; battery packs often use air cooling devices; battery packs are often installed in energy storage cabinets; common air cooling devices usually include a cooling fan and a control module fixedly installed on the energy storage cabinet; the energy storage cabinet has air inlet and exhaust slots that work with the cooling fan; the control module controls the cooling fan to rotate according to the temperature inside the energy storage cabinet, thereby blowing outside air into the energy storage cabinet and exhausting it out through the exhaust slots; the air carries away heat energy during the flow of air in the energy storage cabinet, thereby achieving a cooling effect.

[0004] Common cooling fans are directional blowers. When air flows along a fixed trajectory inside the energy storage cabinet, it can only carry heat from the structures it is in contact with. Because the energy storage cabinet contains a frame for fixing the battery pack and various control components for controlling the input and output of electrical energy, the internal structure of the energy storage cabinet becomes relatively complex. These complex structures are prone to creating heat dissipation dead zones (i.e., structures that are not in contact with the flowing air). This makes it easy for localized heat to accumulate inside the energy storage cabinet, which can affect the normal operation of the equipment. Utility Model Content

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0049] Please see Figures 1-9 As an embodiment of the present utility model, the photovoltaic energy storage station heat dissipation device based on the thermal management system includes multiple sets of fixed shells 2 installed on the top and bottom of the energy storage cabinet 1.

[0050] It also includes a control module 3 and a motor 4 installed on the energy storage cabinet 1, as well as a linkage shaft 5 rotatably installed on the energy storage cabinet 1;

[0051] A main rotating shaft 6 is rotatably mounted on the fixed housing 2, and multiple sets of the main rotating shafts 6 are connected to the linkage rotating shaft 5 by belts; multiple sets of fan blades 7 are mounted on the main rotating shaft 6;

[0052] Multiple sets of swing structures are respectively arranged at the upper and lower ends of the energy storage cabinet 1; including a swing plate 10, which can swing back and forth.

[0053] In this embodiment, the control module 3 is used to detect the real-time temperature inside the energy storage cabinet 1, and can control the working state of the motor 4 according to the temperature value. The working motor 4 can drive the linkage shaft 5 to rotate through the bevel gear set.

[0054] When the linkage shaft 5 rotates, it will drive the main shaft 6 to rotate via the belt, thereby driving multiple sets of fan blades 7 to rotate synchronously. The rotating fan blades 7 blow the air outside the energy storage cabinet 1 into the energy storage cabinet 1, thereby replacing the air inside the energy storage cabinet 1 and cooling the energy storage cabinet 1 to ensure that the energy storage cabinet 1 is not affected by temperature.

[0055] Furthermore, by blowing air simultaneously from the bottom and top of the energy storage cabinet 1, heat dissipation efficiency can be improved.

[0056] When the fan blade 7 rotates, the oscillating structure will move, and multiple sets of oscillating plates 10 will oscillate back and forth. The oscillating plates 10 can continuously change the flow path of the airflow blown by the fan blade 7, which can effectively increase the contact area between the airflow and the various structures inside the energy storage cabinet 1, reduce heat dissipation dead angles, and thus further improve heat dissipation efficiency.

[0057] As a further embodiment of this utility model, the swing structure further includes a swing shaft 8 rotatably mounted on the energy storage cabinet 1; a connecting rod 21 is mounted on the swing shaft 8; a sliding column 2101 is mounted on the end of the connecting rod 21; an mounting plate 9 is mounted on the energy storage cabinet 1; multiple sets of swing plates 10 are rotatably mounted on the mounting plate 9; a slider 1001 is mounted on the swing plate 10; a sliding plate 11 is provided on the mounting plate 9; the sliding plate 11 has a first sliding groove 1101 that slides and engages with the sliding column 2101 and multiple sets of second sliding grooves 1102 that slide and engage with the slider 1001; the swing shaft 8 and the main shaft 6 are connected by a belt.

[0058] In this embodiment, when the main shaft 6 rotates, it drives the swing shaft 8 to rotate via a belt, thereby driving the connecting rod 21 to rotate, which in turn drives the slide column 2101 to rotate synchronously. During this process, the slide column 2101 slides in the first slide groove 1101, and by pressing against the groove wall of the first slide groove 1101, it can drive the slide plate 11 to slide back and forth.

[0059] When the slide plate 11 slides, it will cause the second slide groove 1102 to move synchronously. During this process, the slider 1001 will slide in the second slide groove 1102, and under the squeezing action of the groove wall of the second slide groove 1102, the slider 1001 will drive the swing plate 10 to rotate.

[0060] The reciprocating oscillating plate 10 can continuously change the airflow path blown by the fan blade 7, effectively increasing the contact area between the airflow and various structures inside the energy storage cabinet 1, reducing heat dissipation dead angles, and thus further improving heat dissipation efficiency.

[0061] As a further embodiment of this utility model, a support block 12 is installed on the mounting plate 9; a plurality of rollers 1201 that are rotatably mounted on the support block 12 are engaged with the sliding plate 11.

[0062] In this embodiment, the sliding plate 11 engages with the roller 1201 during its reciprocating movement. This rolling engagement reduces frictional loss between the sliding plate 11 and the support block 12, and effectively reduces noise and vibration generated by the movement of the sliding plate 11, thereby minimizing the impact on various components within the energy storage cabinet 1.

[0063] As a further embodiment of this utility model, an air intake plate 201 is installed on the fixed shell 2; multiple sets of air intake grooves 202 are provided on the air intake plate 201; a fixed column 19 is installed on the air intake plate 201; a rotating disk 18 is rotatably installed on the air intake plate 201; multiple sets of mating grooves 1801 that cooperate with the air intake grooves 202 are provided on the rotating disk 18.

[0064] In this embodiment, rotating the rotating disk 18 causes the mating groove 1801 to rotate, thereby changing the conduction area between the mating groove 1801 and the air inlet groove 202, thereby controlling the amount of outside air entering.

[0065] The control module 3 can control the rotation speed of the fan blade 7 according to the temperature value inside the energy storage cabinet 1 (higher temperature, faster rotation; lower temperature, slower rotation), thereby reducing energy loss. It should be noted that this is existing technology. When the fan blade 7 rotates, it can drive the rotating disk 18 to rotate, thereby changing the conduction area, and the rotation angle of the rotating disk 18 is directly proportional to the rotation speed of the fan blade 7. That is, when the temperature of the energy storage cabinet 1 is low, the rotation speed of the fan blade 7 is low, the conduction area of ​​the air intake slot 202 is small, and the amount of air entering per unit time is relatively low. At this time, the heat dissipation needs can be met, and the problem of external dust entering the energy storage cabinet 1 and contaminating or even damaging internal components due to the excessive conduction area of ​​the air intake slot 202 can be avoided. When the temperature of the energy storage cabinet 1 is high, the rotation speed of the fan blade 7 is fast, the conduction area of ​​the air intake slot 202 is large, and the amount of air entering per unit time is relatively large. At this time, the problem of rapid cooling and heat dissipation can be met, and the noise generated by airflow can be reduced.

[0066] As a further embodiment of this utility model, a centrifugal disc 13 is installed on the main rotating shaft 6; multiple centrifugal blocks 14 are slidably fitted on the centrifugal disc 13; a telescopic sleeve 1401 is installed on the centrifugal block 14; a movable sleeve 15 is sleeved on the main rotating shaft 6; and a telescopic column 1501 that slidably fits with the telescopic sleeve 1401 is installed on the movable sleeve 15.

[0067] As a further embodiment of this utility model, a contact sleeve 16 that cooperates with the movable sleeve 15 is slidably installed on the fixed column 19; a groove 1601 is provided on the contact sleeve 16; a rotating sleeve 17 is installed on the rotating disk 18; and a protruding column 1701 that slides and engages with the groove 1601 is installed on the rotating sleeve 17.

[0068] In this embodiment, when the main rotating shaft 6 rotates, it will drive the centrifugal disk 13 to rotate synchronously, thereby driving the centrifugal block 14 to rotate. Under the action of centrifugal force, the centrifugal block 14 will slide on the centrifugal disk 13 and gradually move away from the main rotating shaft 6. The sliding distance is proportional to the rotational speed of the main rotating shaft 6.

[0069] When the centrifuge block 14 slides, it will drive the movable sleeve 15 to gradually move away from the centrifuge plate 13 through the telescopic column 1501 and the telescopic sleeve 1401. During this process, the telescopic column 1501 will slide outward inside the telescopic sleeve 1401. The distance that the movable sleeve 15 moves is proportional to the distance that the centrifuge block 14 slides.

[0070] When the movable sleeve 15 moves, it will press against the contact sleeve 16, thereby driving the contact sleeve 16 to move synchronously, which in turn drives the inclined groove 1601 to move synchronously. During this process, the protruding column 1701 will slide in the inclined groove 1601. Through the pressure of the groove wall of the inclined groove 1601 on the protruding column 1701, the rotating sleeve 17 can be driven to rotate, thereby driving the rotating disk 18 to rotate, which in turn drives the mating groove 1801 to rotate. The rotation angle of the mating groove 1801 is proportional to the distance that the movable sleeve 15 moves.

[0071] When the temperature of the energy storage cabinet 1 is low, the fan blade 7 rotates at a low speed, the conduction area of ​​the air intake slot 202 is small, and the amount of air entering per unit time is relatively low. This satisfies the heat dissipation requirements while preventing external dust from entering the energy storage cabinet 1 and contaminating or even damaging internal components due to an excessively large conduction area of ​​the air intake slot 202. Conversely, when the temperature of the energy storage cabinet 1 is high, the fan blade 7 rotates at a high speed, the conduction area of ​​the air intake slot 202 is large, and the amount of air entering per unit time is relatively large. This satisfies the need for rapid cooling and heat dissipation while also reducing the noise generated by airflow.

[0072] As a further embodiment of this utility model, a return spring 20 is wrapped around the fixed column 19; the two ends of the return spring 20 respectively abut against the abutting sleeve 16 and the air intake plate 201.

[0073] In this embodiment, when the contact sleeve 16 slides on the fixed column 19 under the compression of the movable sleeve 15, it compresses the return spring 20; the compression of the return spring 20 is proportional to the distance the movable sleeve 15 moves. When the control module 3 controls the main rotating shaft 6 to reduce its speed, the elastic force of the return spring 20 will drive the contact sleeve 16 and the movable sleeve 15 to move towards the centrifugal disk 13, thereby driving the rotating disk 18 to rotate in the opposite direction to reduce the conduction area of ​​the air inlet slot 202; and it can also drive the centrifugal block 14 to slide on the centrifugal disk 13 towards the main rotating shaft 6; during this process, the telescopic column 1501 will slide inward within the telescopic sleeve 1401 to complete the reset. The return spring 20 can drive the device to reset, thereby improving the stability of the device.

[0074] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
