Description

Technical Field

[0001] This invention relates to an energy storage cabinet, and more specifically, to a combined system of an electrical control module and a cooling module. Background Technology

[0002] The energy storage cabinet mainly consists of battery modules, high-voltage modules, energy storage converters (PCS), thermal management systems, and electrical control modules. The power storage converter (PCS) mainly consists of a DC / AC bidirectional converter and a control unit. It can control the charging and discharging process of the battery system, regulate the grid power, and obtain battery status information through a communication interface. The PCS generates a lot of heat during operation. Therefore, to ensure the safe, stable and efficient operation of the PCS, it is necessary to use an air-cooled cooling module for exhaust cooling. This makes the power storage converter (PCS) and the cooling module arranged at the front and back in the cabinet. The front of the cabinet needs to house core components such as energy storage converters and inverters. To avoid space conflicts, the empty space at the rear is used to place electrical control modules, which include components such as circuit breakers, fuses, relays, and sensors.

[0003] Therefore, in existing cabinet designs, both the cooling module and the electrical control module are located at the rear of the cabinet and are often arranged vertically adjacent to each other.

[0004] Due to the limited space behind the cabinet, especially when the back of the cabinet is placed against the wall, it is difficult to disassemble and install the electrical control module. Furthermore, due to the limited space behind the cabinet, it is difficult to install an independent cooling module to dissipate heat from the electrical control module. Therefore, existing energy storage cabinets lack a structure that simultaneously satisfies the requirements of air cooling for the electrical control module and ease of disassembly and assembly. Summary of the Invention

[0005] The purpose of this invention is to provide a combined system of an electrical control module and a cooling module. The electrical control module, which is shaped like a bamboo tube, allows for easy assembly and disassembly in the narrow space of the cabinet against the wall. Furthermore, the shared fan in the adjacent storage layer enhances the cooling and heat dissipation effect of the electrical control module.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: A combined system of an electronic control module and a cooling module includes a cabinet, the cabinet comprising a back panel and a door panel. The cabinet has two stacked storage layers, a first layer and a second layer, with energy storage application modules inserted at the front of each layer. At the rear of each layer facing the back panel are two rear storage spaces, a first rear space and a second rear space. The second rear space includes: rails fixed to both side walls; multiple loading plates connected by flexible wires, adjacent loading plates being interconnected and rotatable; each loading plate has corresponding components and wire grooves; when the loading plates are inserted into the rails sequentially, the rear loading plate is suspended during insertion; the rails have locking blocks and elastic elements that drive the locking blocks to insert into the end faces of the loading plates; the loading plates have locking holes for the locking blocks to insert; the rails have unlocking plates that disengage the locking blocks from the loading plates; the first rear space also includes a fan; and there are air vents between the first and second rear spaces.

[0008] Preferably, the loading plate is equipped with a cable tie; Wiring is secured by wire harnesses when arranged on each loading plate; For wiring located on the two loading plates, sufficient wiring slack is required to ensure that the rotation of the loading plates is not constrained by the wiring.

[0009] Preferably, the cross-section of the insert rail is U-shaped, and the two ends of the loading plate are inserted into the insert rails on both sides; The unlocking plate slides inside the insertion rail, and the unlocking plate is fixed with a lever that extends upwards out of the insertion rail; The lever drives the unlocking plate to move back and forth in the direction of the notch in the insertion rail.

[0010] Preferably, the unlocking plate has an insertion hole, the lock block slides into the insertion hole, and a retaining edge is fixed at the tail of the lock block to prevent it from sliding out of the insertion hole; under the drive of the elastic element, the lock block is inserted into the lock hole to lock the loading plate; by moving the lever, the unlocking plate squeezes the elastic element and drives the lock block to disengage from the lock hole to unlock.

[0011] Preferably, the end of the locking block facing the loading plate is inclined; when the loading plate is inserted, it abuts against the inclined surface to achieve automatic retraction of the locking block; the number of locking blocks matches the number of loading plates, and the size of the locking blocks gradually decreases from the inlet end to the end of the rail to achieve individual pairing and locking of the corresponding locking blocks and loading plates.

[0012] Preferably, the cabinet includes a control panel, and an electric push rod controlled by the control panel is installed in the first rear space. The fan is equipped with a sealing plate; the electric push rod drives the fan to move to adjust the opening and closing size of the air vents.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Example 1: A combined system of an electronic control module and a cooling module, referring to... Figure 1 and Figure 2 A rectangular metal cabinet 1 includes a door panel 11 and a back panel 12 arranged opposite to each other. The door panel 11 can be rotated to open and close. The door panel 11 and the back panel 12 are provided with ventilation mesh 13, which is formed by laser drilling of the panel. In this design, the door panel 11 is used for air intake and the back panel 12 is used for air exhaust.

[0022] Reference Figure 2 and Figure 3 Inside cabinet 1, the upper part contains multiple energy storage units, which are battery modules. The lower part of cabinet 1 is provided with a storage layer, in which an energy storage application module is inserted from the front of the cabinet door. The energy storage application module includes a high-voltage module, an energy storage converter 31 (PCS) or a liquid chiller, etc.

[0023] There are two storage layers, namely storage layer 1 21 and storage layer 22. The storage layer is a space layer inside the cabinet 1 that is divided by a partition fixed with screws. The two ends of storage layer 1 21 and storage layer 22 face the door panel 11 and the back panel 12 respectively. The two ventilation nets 13 at the front and back of the door panel 11 and the back panel 12 allow airflow to pass through the storage layer.

[0024] The bottom shelf is the first shelf 21, and the second shelf 22 is stacked on top of the first shelf 21.

[0025] Both the first storage layer 21 and the second storage layer 22 are rectangular partitions, each with four sides, and both the front and rear ends are sealed with ventilation nets 13.

[0026] An energy storage converter 31 is inserted at the front of the first storage layer 21, and a high-voltage box is inserted at the front of the second storage layer 22.

[0027] After the energy storage converter 31 is installed on the first storage layer 21, a rear space 211 is left at its rear end. After the high-voltage box is installed, the rear end of the second storage layer 22 has a second rear space 222.

[0028] The first rear space 211 is equipped with a fan 32.

[0029] Reference Figure 3 and Figure 4 The second rear space 222 contains multiple components 41 and wire troughs 42. The components 41 include relays, air switches, circuit breakers, etc. The components 41 and wire troughs 42 are distributed and installed on the corresponding loading plates 51.

[0030] Reference Figure 2 The first rear space 211 and the second rear space 222 are separated by a plate, and the plate has vents 300, which are oval in shape.

[0031] When the fan 32 draws air to cool the first storage layer 21, the airflow in the second storage layer 22 is also accelerated by the fan 32 due to the connection effect of the air vents 300, which increases the airflow speed in the second storage layer 22 and improves the cooling effect of the second storage layer 22.

[0032] Reference Figure 4 and Figure 5 The two side walls of the No. 1 rear space 211 are welded and fixed with insert rails 6, and the cross section of the insert rails 6 is U-shaped. The loading plate 51 is inserted into the rail 6 for installation, and the components 41 and the wire groove 42 are fixed on the loading plate 51.

[0033] The loading plate 51 is a rectangular metal plate, and there are four of them in this embodiment.

[0034] Adjacent loading plates 51 are connected to each other and can rotate relative to each other. The two ends of two adjacent loading plates 51 are connected by a flexible wire 52. The four loading plates 51 are connected together in a bamboo-like structure. The flexible cord 52 can be nylon cord or metal cord, etc. In other embodiments, adjacent loading plates 51 can be hinged by a pivot. The hinge must have sufficient rotational margin to meet the requirement that the loading plate 51 hangs down around the hinge point.

[0035] Components 41 and wire slots 42 are arranged alternately on the loading plate 51. The wiring of components 41 extends out and is located in the adjacent wire slot 42, so that the wiring of components 41 on the front loading plate 51 can be concentrated in the wire slots 42 of the rear loading plate 51.

[0036] The wiring in each wire trough 42 converges at the fourth loading plate 51 below and forms an integrated wire harness 43. The integrated wire harness 43 can be fitted with a heat shrink sleeve. The integrated wire harness 43 is equipped with a plug 44 on the outside, which is of course used to connect to the socket of the cabinet 1.

[0037] Reference Figure 6 The loading plate 51 is equipped with a wire harness 53, which is a round plastic buckle with an opening for inserting wires. When wires are arranged on each loading plate 51, they are constrained by the wire harness 53, thus avoiding the wires from becoming tangled and allowing them to be bundled together with cable ties. For wires located on two loading plates 51, it is necessary to ensure that the wires have sufficient slack to allow the loading plates 51 to rotate relative to each other without being constrained by the wires. Because the wires themselves are flexible, and with a certain slack, the wires will not pull on their fixed ends when the loading plates 51 rotate relative to each other, thereby preventing the fixed ends from falling off the component 41.

[0038] When the user holds the upper loading plate 51, the lower loading plate 51 can be suspended, which reduces the possibility of the loading plate 51 colliding with the wall behind it, making it possible to remove it from the small space behind the cabinet 1.

[0039] The flexible connection loading plate 51 assembly needs to be stably installed inside the cabinet 1, and its installation structure is as follows.

[0040] The four loading plates 51 are inserted into the two side rails 6 in sequence, and the rear loading plate 51 can be suspended during the insertion process; when all four loading plates 51 are inserted into the rails 6, they can be placed stably.

[0041] However, since the loading plates 51 are connected by a soft connection, in order to ensure the stable assembly of the loading plates 51, a locking component is required to fix the loading plates 51 and the rail 6. The locking component includes a locking block 81, an elastic element 7, an unlocking plate 91, and a lock hole 54.

[0042] The flexible cable 52 connecting the loading plates 51 has a reasonable distance from the locking block 81, so that the locking block 81 will not interfere with or constrain the flexible cable 52 when it is extended.

[0043] Reference Figures 6-8 The cross-sections of the two insert rails 6 are U-shaped, and the notches of the two insert rails 6 are arranged facing each other; An unlocking plate 91 slides within the insertion rail 6; the unlocking plate 91 is a long rectangular plate. The unlocking plate 91 has an insertion hole 92, the locking block 81 is slidably inserted into the insertion hole 92, and the tail of the locking block 81 is fixed with a stop 82 to prevent it from sliding out of the insertion hole 92. An elastic element 7 is installed inside the insertion rail 6. The elastic element 7 is a spring. One end of the spring is hooked to the inner wall of the insertion rail 6, and the other end of the spring abuts against the locking block 81. Therefore, the compressed spring pushes the locking block 81 and simultaneously pushes the unlocking plate 91 to move.

[0044] The unlocking plate 91 slides within the insertion rail 6. The unlocking plate 91 is fixed with an upwardly extending lever 93. An upper hole is provided on the upper surface of the insertion rail 6, and the lever 93 extends out of the upper hole. Under the push of the spring, the blocking relationship between the lever 93 and the wall of the upper hole also restricts the unlocking plate 91 from sliding off the insertion rail 6.

[0045] The unlocking plate 91 is provided with four locking blocks 81, and the four loading plates 51 are provided with four locking holes 54. The four locking blocks 81 and the four locking holes 54 correspond one-to-one.

[0046] The working principle is as follows: the worker moves the lever 93 to retract the locking block 81, and then the loading plate 51 is inserted into the insertion rail 6 in sequence. The worker releases the lever 93, and the spring drives the locking block 81 to push out. At this time, the worker slightly slides the loading plate 51 on the insertion rail 6 to make a fine adjustment of its position, so that the locking block 81 is inserted into the lock hole 54, thereby fixing the insertion rail 6 and the loading plate 51. Of course, a limiting member 61 can also be set at the insertion end of the insertion rail 6. The limiting member 61 can be a screw. When the deepest loading plate 51 of the insertion rail 6 touches the limiting member 61, it indicates that the initial positioning of the sliding has been completed.

[0047] Of course, in other embodiments, for the two insert rails 6, it is sufficient to set a locking block 81 on one of the insert rails 6, because the locking of the insert rail 6 and the loading plate 51 on one side can also complete the fixed relationship, and the locking relationship of only one side of the insert rail 6 is convenient for workers to unlock. As for the other side of the insert rail 6, it is only used for the sliding of the loading plate 51.

[0048] Reference Figure 7 and Figure 8 The end of the locking block 81 that is inserted into the loading plate 51 is an inclined surface 83; when the loading plate 51 is inserted, it abuts against the inclined surface 83, thereby realizing the automatic retraction of the locking block 81. Since the number of locking blocks 81 matches the number of loading plates 51, the size of the locking blocks 81 gradually decreases from the inlet end to the end of the rail 6 to achieve individual pairing and locking of the corresponding locking blocks 81 and loading plates 51, and the size of the locking hole 54 of the loading plate 51 matches the corresponding locking block 81.

[0049] The locking block 81 at the front end of the insertion rail 6 is large, while the locking hole 54 of the first inserted loading plate 51 is small. Therefore, after the loading plate 51 is inserted, only the locking block 81 and the locking hole 54 at the matching position can lock together. The advantage of this design is that when the loading plate 51 is inserted into the insertion rail 6, the user does not need to push the lever 93 aside, because the force generated by the collision between the inclined surface 83 of the locking block 81 and the loading plate 51 will push the locking block 81 aside, which also makes the installation of the loading plate 51 more convenient.

[0050] Reference Figure 9 and Figure 10 The working process is explained as follows: the back of the energy storage cabinet is close to the wall, with a gap of only 40cm. When the worker needs to take out the loading plate 51 assembly, each loading plate 51 is taken out and hung downwards. In this way, the loading plate 51 assembly will not come into contact with the wall due to downward deformation, which effectively solves the problem of the loading plate 51 assembly and the wall blocking each other.

[0051] Therefore, in this design, for the two rear spaces, the first rear space 211 in the lower part is equipped with a fan 32. The fan 32 is used to cool the first rear space 211. The number of fans 32 can be 2, 3, 4 or 6, etc. The upper rear space 222 is used to place modular components 41, which makes it easier for workers to install the components 41 as a whole by disassembling and assembling them. The bamboo-slip-like connection method allows the loading plates 51 to be reshaped, making it easier to take out the loading plates 51 and assemble them in a narrow wall space. The airflow between the first rear space 211 and the second rear space 222 through the vent 300 improves the air-cooling effect of the second rear space 222, making up for the lack of sufficient space to install an independent exhaust device after the second rear space 222 has installed components 41.

[0052] Example 2, a combined system of an electronic control module and a cooling module, differs from the rest of Example 1 in that, referring to... Figure 11 and Figure 12 The inner wall of the first rear space 211 is welded with a baffle 500. The baffle 500 is a rectangular ring-shaped frame. Therefore, the baffle 500 has a hollowed-out frame hole in the middle to form a frame hole for airflow. The front and rear ends of the housing of the energy storage converter 31 are provided with ventilation mesh, so the airflow can pass through the energy storage converter 31 and flow in the first storage layer 21.

[0053] The baffle 500 acts as a partition, and the inner end of the energy storage converter 31 abuts against the baffle 500 to limit the depth of the energy storage converter 31 within the first storage layer 21, thereby achieving the purpose of inserting and positioning the energy storage converter 31.

[0054] The fan 32 is installed at the left end of the first rear space 211. Four guide rails 400 are welded and fixed to the baffle 500. One end of the four guide rails 400 is vertically welded to the side of the baffle 500, and the other end of the four guide rails 400 is fixed to the end frame. The end frame is fixed at the left end of the first rear space 211, and the fan 32 can move freely within the end frame.

[0055] There are two fans 32, and the two fans 32 are fixed to the outer frame by screws.

[0056] A sliding hole is made on the outer frame, and the guide rail 400 is inserted into the sliding hole, so the outer frame together with the fan 32 slides on the guide rail 400; A sealing plate 201 is fixed to the outer frame of the fan 32 by screws; The sealing plate 201 is a right-angled plate. One side of the sealing plate 201 is fixed to the outer frame of the fan 32, and the other side of the sealing plate 201 is arranged facing the top of the first storage layer 21.

[0057] The two panel bends of the sealing plate 201 are equipped with reinforcing ribs to increase the structural strength of the bends.

[0058] The sealing plate 201 moves back and forth to control the opening and closing size of the air vent 300.

[0059] At station number one, sealing plate 201 blocks vent 300, reducing the downward airflow of vent 300.

[0060] The sealing plate 201 moves back and forth to control the opening and closing size of the vent 300.

[0061] Above the first rear space 211 is the second storage layer 22, so the vent 300 connects the first rear space 211 and the second rear space 222.

[0062] Reference Figure 14When the fan 32 draws air into the first storage layer 21, the air vent 300 is closed by 90%, which mainly accelerates the air flow in the first storage layer 21 and improves the air cooling effect of the first storage layer 21.

[0063] Reference Figures 12-14 With the vents open, some airflow flows through the upper vents 300, thus significantly improving the air-cooling effect of the fan 32 pairs and the second rear space 222 pairs.

[0064] When the room temperature is high, such as 25 degrees Celsius or higher, the heat dissipation of the energy storage converter 31 is large. The fan 32 should provide high-flow air cooling for the energy storage converter 31 on the first storage layer 21. Maintaining the normal operation of the energy storage converter 31 is the priority. Therefore, at this time, the sealing plate 201 is moved to the first work station.

[0065] When the room temperature is low, such as less than 25 degrees Celsius, the heat dissipation pressure of the energy storage converter 31 is small. The fan 32 can assist other storage layer units in heat dissipation, improve the ability of adjacent components of the energy storage cabinet to coordinate cooling, and increase the overall cooling capacity.

[0066] In the above structure, the movement of the fan 32 lacks a power source. An electric push rod 202 is installed in the first storage layer 21. The electric push rod 202 is located on one side of the fan 32. The movement of the fan 32 will not interfere with the electric push rod 202. The main body of the electric actuator 202 is fixed to the bottom of the first rear space 211 by screws; The rod of the electric push rod 202 is fixed to the outer frame of the fan 32, so the extension and retraction of the electric push rod 202 drives the fan 32 to move back and forth on the guide rail 400.

[0067] The working principle is: referencing Figures 13-15 The arrows in the diagram indicate the direction of the main airflow.

[0068] The user sets a threshold temperature, such as room temperature 25 degrees Celsius. A temperature display is installed on the outside of cabinet 1, and the temperature display is connected to a temperature detector. The temperature detector is located in the first rear space 211.

[0069] When the user observes that the actual temperature is greater than or equal to the temperature threshold, the user operates the control board 101. The control board 101 sends a signal to the electric push rod 202. The electric push rod 202 drives the fan 32 to move to the first work station. At the first work station, the sealing plate 201 blocks 90% of the air hole 300, and the fan 32 provides air cooling for the large airflow in the first rear space 211. When the user observes that the actual temperature is lower than the temperature threshold, the electric push rod 202 drives the fan 32 to move to the second work station. At the second work station, the fan 32 can assist other storage layer units in heat dissipation, improve the ability of adjacent components of the energy storage cabinet to coordinate cooling, and increase the overall cooling capacity.

[0070] Example 3, a combined system of an electronic control module and a cooling module, differs from Example 2 in that, referring to... Figure 12 The control board 101 is electrically connected to a temperature sensor 102, which is located in the first shelf layer 21. The temperature threshold range corresponds to the opening degree of an independent vent 300. As the temperature increases, the opening degree of the vent 300 in the temperature threshold range gradually decreases. When the temperature sensor 102 detects that the temperature is within the temperature threshold range, the vent 300 opens according to the corresponding opening degree.

[0071] The control board 101 has 9 temperature threshold ranges: [0-t1), [t1-t2), [t2-t3), [t3-t4), [t4-t5), ... [t8-90). t1 is 10 degrees; t2 is 20 degrees; t3 is 30 degrees; t4 is 40 degrees; t5 is 50 degrees; t6 is 60 degrees; t7 is 70 degrees; t8 is 80 degrees; Temperature sensor 102 detects the actual temperature, which falls within a specified temperature threshold range. Each temperature threshold range corresponds to an independent vent 300 opening / closing degree value. Control board 101 receives the signal of the opening / closing degree value. When the temperature sensor 102 detects a temperature less than 0, the room temperature is low. The energy storage converter 31 itself has good heat exchange performance. The vent 300 can be fully opened to increase the overall heat dissipation performance of the upper and lower spaces. Temperature sensor 102 detects temperature values ​​within [0-t1), and vent 300 is 90% open. Temperature sensor 102 detects temperature values ​​within [t1-t2), and vent 300 is 80% open. Temperature sensor 102 detects temperature values ​​within [t2-t3), and vent 300 is 70% open. Temperature sensor 102 detects temperature values ​​in the range [t3-t4), and vent 300 is open to 60%. Temperature sensor 102 detects temperature values ​​within [t4-t5), vent 300 is open 50%; Temperature sensor 102 detects temperature values ​​in the range of [t5-t6), and vent 300 is open to 40%. Temperature sensor 102 detects temperature values ​​in the range [t6-t7), and vent 300 is open by 30%. Temperature sensor 102 detects temperature values ​​in the range of [t7-t8), and vent 300 is open by 20%. Temperature sensor 102 detects temperature values ​​within [t8-90], vent 300 is open by 10%; When the temperature sensor 102 detects a temperature greater than or equal to 90 degrees Celsius, a fire may be about to occur. The vent 300 is completely closed to achieve isolation. If a fire subsequently occurs, the closure of the vent can delay the spread of the fire.
