Description

Technical Field

[0001] This utility model relates to the field of heat dissipation structure technology, specifically to a modular heat dissipation substrate structure for a new energy control cabinet. Background Technology

[0002] With the rapid development of new energy technologies, the power density of new energy control cabinets such as photovoltaic inverters and energy storage converters is constantly increasing. The heat generated by internal electrical components (such as IGBTs, capacitors, inductors, etc.) during operation is also increasing, which puts forward strict requirements on the heat dissipation function of new energy control cabinets.

[0003] Traditional heat dissipation methods (such as natural convection and fixed ventilation holes) are no longer sufficient to meet the heat dissipation requirements of high-power devices, leading to the following problems:

[0004] First, static heat dissipation structures cannot dynamically adjust the airflow according to temperature changes, which can easily cause component performance to degrade or be damaged at high temperatures.

[0005] Secondly, open ventilation holes are prone to letting in dust, insects, or foreign objects, which can affect the lifespan of components inside the cabinet.

[0006] Third, most of them are one-piece designs, which require the whole unit to be replaced when damaged, making repairs inconvenient. Utility Model Content

[0007] To address the aforementioned problems, this utility model discloses a modular heat dissipation substrate structure for a new energy control cabinet.

[0008] The technical solution of this utility model is: a modular heat dissipation substrate structure for a new energy control cabinet, including a cabinet with an installation port on the side wall, wherein a heat dissipation substrate is snapped into the installation port;

[0009] The heat dissipation substrate includes a mounting plate that is fastened to the mounting opening, an adjustable heat dissipation plate connected to the outer wall of the mounting plate, and an outer heat dissipation plate connected to the adjustable heat dissipation plate and having multiple heat dissipation holes on its side wall.

[0010] The adjustable heat sink includes an adjustable mounting frame with closed structures at both the top and bottom, multiple adjustable plates respectively located on the front and rear sides of the adjustable mounting frame, and miniature rotating gears located on each of the adjustable plates. The upper and lower ends of each adjustable plate are rotatably connected to the inner wall of the adjustable mounting frame. The miniature rotating gears located in the same horizontal direction are meshed and connected by a chain, and one of the miniature rotating gears is driven by a servo motor.

[0011] Furthermore, a cooling fan is installed inside the adjustment mounting frame, and protective nets are provided on the front and rear sides of the mounting plate and the outer heat dissipation plate, respectively.

[0012] Note: When dissipating heat inside the cabinet, the cooling fan, based on the specific heat dissipation structure of the heat dissipation base plate, can accelerate the outflow of heat from the cabinet and improve heat dissipation efficiency. At the same time, protective nets are provided on the front and rear sides of the mounting plate and the external heat dissipation plate. The purpose is to protect the outer walls of each adjustment plate and prevent external debris or flying insects from accidentally entering the cabinet through the space between two adjacent adjustment plates when the adjustment plates are parallel to each other, thus ensuring the long-term stable operation of the components inside the cabinet.

[0013] Furthermore, each of the adjustment plates is provided with a mounting frame at both the front and rear edges, and the side wall of the mounting frame is provided with a mounting insertion groove, in which an elastic protective strip is installed.

[0014] Note: When each adjusting plate rotates, the elastic protective strip can buffer the impact force between two adjacent adjusting plates, reducing their wear rate. At the same time, the elastic protective strip can be detached and installed through the mounting frame, which facilitates the replacement of the elastic protective strip and ensures the service life of the entire structure.

[0015] Furthermore, the adjustable heat sink plate is engaged with the adjustable mounting frame, and the adjustable mounting frame is engaged with the mounting buckle plate.

[0016] Note: By limiting the interlocking between the heat sink and the mounting frame, as well as between the mounting frame and the mounting clip, it is easy to quickly separate or modularly assemble, improving work efficiency.

[0017] Furthermore, a temperature sensor is installed on the inner wall of the cabinet, and the temperature sensor is connected to an external controller. The servo motor is also connected to an external controller.

[0018] Description: The internal temperature of the cabinet is detected in real time by a temperature sensor, and the detected data is transmitted to an external controller. The external controller controls the rotation of a servo motor, which in turn drives a connected miniature rotating gear. Other miniature rotating gears rotate synchronously under the linkage of a chain, thereby automatically adjusting the distance between the various heat dissipation plates. At the same time, it works in conjunction with the heat dissipation holes to improve heat dissipation efficiency.

[0019] The beneficial effects of this utility model are:

[0020] The modular heat dissipation base plate structure of this utility model for new energy control cabinets allows for adjustment of the heat dissipation method according to the internal temperature of the cabinet. Initial heat dissipation is achieved through natural convection via the external heat dissipation plate, requiring no additional energy consumption. When the internal temperature of the cabinet rises, secondary heat dissipation is achieved through forced convection via the cooling fan and by adjusting the expansion of the heat dissipation plate to increase the ventilation surface. The heat dissipation intensity is adjusted in real time according to temperature changes to avoid energy waste caused by excessive heat dissipation. This design is particularly suitable for the intermittent high-load operation characteristics of new energy control cabinets. The mounting plate, the adjustable heat dissipation plate, and the external heat dissipation plate adopt a snap-fit ​​design, supporting quick assembly and disassembly, facilitating maintenance or replacement of individual components, and reducing operation and maintenance costs.

Detailed Implementation

[0028] Example 1: As Figure 1 As shown, a modular heat dissipation substrate structure for a new energy control cabinet includes a cabinet 1 with an installation port 10 on the side wall, and a heat dissipation substrate 2 is snapped into the installation port 10.

[0029] The heat dissipation substrate 2 includes a mounting plate 20 that is fastened to the mounting opening 10, an adjustable heat dissipation plate 21 connected to the outer wall of the mounting plate 20, and an outer heat dissipation plate 22 connected to the adjustable heat dissipation plate 21 and having nine heat dissipation holes 220 on its side wall.

[0030] like Figure 2 , 3 As shown in Figure 4, the adjustable heat sink 21 includes an adjustable mounting frame 210 with closed structures at both the top and bottom, 14 adjustable plates 211 respectively located on the front and rear sides of the adjustable mounting frame 210, and micro rotating gears 212 on each adjustable plate 211. The top and bottom ends of each adjustable plate 211 are rotatably connected to the inner wall of the adjustable mounting frame 210. The micro rotating gears 212 located in the same horizontal direction are connected by a chain 23, and one of the micro rotating gears 212 is driven by a servo motor 213. The micro rotating gears 212, the chain 23 and the servo motor 213 all adopt existing technologies. For example, the micro rotating gears 212 can be planetary gear reducers of model ZPN62-24-40-30S, the chain 23 can be a gear chain, and the servo motor 213 can be a servo motor of model 1025N5M04-115-12.0.

[0031] A cooling fan 11 is installed inside the adjustable mounting frame 210. Protective nets 24 are provided on the front and rear sides of the mounting plate 20 and the outer heat dissipation plate 22. When the cabinet 1 is cooled, the cooling fan 11 can accelerate the heat out of the cabinet 1 and improve the heat dissipation efficiency based on the specific heat dissipation structure of the heat dissipation base plate 2. At the same time, the protective nets 24 are provided on the front and rear sides of the mounting plate 20 and the outer heat dissipation plate 22 to protect the outer wall of each adjusting plate 211 and prevent external debris or flying insects from accidentally entering the cabinet 1 through the space of two adjacent adjusting plates 211 when the adjusting plates 211 are parallel to each other, so as to ensure the long-term stable operation of the components inside the cabinet 1. The cooling fan 11 adopts existing technology, such as the cooling fan of model 115X-1700.

[0032] like Figure 5 , 6 As shown, each adjusting plate 211 has a mounting frame 214 on both the front and rear sides. The side wall of the mounting frame 214 has a mounting insertion groove 215. An elastic protective strip 216 is installed in the mounting insertion groove 215. When each adjusting plate 211 rotates, the elastic protective strip 216 can buffer the impact force between two adjacent adjusting plates 211 and reduce their wear rate. At the same time, the elastic protective strip 216 can be detached and installed through the mounting frame 214, which facilitates the replacement of the elastic protective strip 216 and ensures the service life of the entire structure. The elastic protective strip 216 is made of soft silicone material in the prior art.

[0033] The heat sink 21 is snapped together with the adjustment mounting frame 210 and the adjustment mounting frame 210 is snapped together with the mounting buckle 20. By limiting the snapping together between the heat sink 21 and the adjustment mounting frame 210 and the adjustment mounting frame 210 and the mounting buckle 20, it is convenient to quickly separate or modularly assemble, thereby improving work efficiency. The snapping method can be mortise and tenon or snap-fit ​​connection.

[0034] A temperature sensor 12 is installed on the inner wall of the cabinet 1. The temperature sensor 12 is connected to an external controller, and the servo motor 213 is also connected to the external controller. The temperature sensor 12 detects the internal temperature of the cabinet 1 in real time and transmits the detected data to the external controller. The external controller controls the rotation of the servo motor 213, which drives the connected miniature rotating gear 212 to rotate. The other miniature rotating gears 212 also rotate synchronously under the linkage of the chain 23, thereby achieving the purpose of automatically adjusting the distance between the various heat dissipation plates 21. At the same time, it works with the heat dissipation holes 220 to dissipate heat and improve the heat dissipation efficiency. The temperature sensor 12 and the external controller both adopt existing technologies. For example, the temperature sensor 12 can be a DS18B20 temperature sensor, and the external controller is an Allen-Bradley CompactLogix 5380 series PLC. It is common knowledge in the field that the external controller controls the operation of the servo motor 213 based on the temperature measured by the temperature sensor 12. The principle and process will not be described in further detail here.

[0035] The heat dissipation principle of the modular heat dissipation substrate structure of the new energy control cabinet in this embodiment includes the following steps:

[0036] S1. Under normal circumstances, the heat generated by the operation of the electrical components in cabinet 1 is dissipated through the mounting port 10 and the heat dissipation hole 220.

[0037] S2. The internal temperature of the cabinet 1 is detected in real time by the temperature sensor 12 and the detection data is transmitted to the external controller. When the internal temperature of the cabinet 1 exceeds 55°C, the external controller controls the cooling fan 11 to start. The operation of the cooling fan 11 accelerates the dissipation of heat inside the cooling fan 11. At the same time, the external controller controls each servo motor 213 to rotate in the forward direction. The servo motor 213 drives the connected micro rotating gear 212 to rotate. The other micro rotating gears 212 also rotate synchronously under the linkage of the chain 23. At this time, each adjustment plate 211 rotates to the same level. The space between two adjacent adjustment plates 211 can accelerate heat dissipation.

[0038] S3. When the temperature sensor 12 detects that the internal temperature of the cabinet 1 is lower than 30°C, it transmits the detection data to the external controller. The external controller then controls the cooling fan 11 to shut down and controls each servo motor 213 to rotate in reverse. This causes the servo motor 213 to drive the connected micro rotating gear 212 to rotate, and the other micro rotating gears 212 also rotate synchronously under the linkage of the chain 23 until the adjustment plates 211 abut against each other, at which point the servo motor 213 is turned off.
