DETAILED DESCRIPTION

[0024] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0025] See also Figure 1-9 ,like Figure 1 As shown, this embodiment provides an intelligent heat dissipation system for a power cabinet, including a service end 101 and a temperature control end 103, wherein the service end 101 and the temperature control end 103 are communicatively connected via a network 102, wherein:

[0026] The server 101 is used to obtain and store the temperature monitoring data and equipment status data uploaded by the temperature control terminal 103 through the network 102. Specifically, the temperature monitoring data may include regional temperature data. The power cabinet is usually composed of multiple areas, each of which may have different temperature distributions. Therefore, it is necessary to monitor the temperature data of each area in order to accurately control the temperature control terminal 103. It may also include the temperature of the main heating components. In the power cabinet, some key electrical components may generate high heat, such as transformers. Monitoring the temperature data of these main heating components can help to detect temperature anomalies in a timely manner and take corresponding measures. It may also include temperature change trends. In addition to real-time temperature data, it is also necessary to analyze temperature change trends to predict future temperature changes and adjust the operating status of the temperature control terminal 103 in advance. It may also include temperature adjustment thresholds, which are preset upper and lower temperature thresholds. When the temperature exceeds or falls below the set threshold, the system will issue an alarm or take corresponding measures to avoid equipment damage or safety risks caused by temperature anomalies.

[0027] Specifically, the status data of the temperature control end 103 can be information about the working status of the temperature control end 103, and can include working status, recording the working status of the temperature control end 103, including on, off, standby, etc. By monitoring the working status, it can be understood whether the temperature control end 103 is working normally; it can also include fault alarm. When the temperature control end 103 fails or is abnormal, the fault information can be recorded and an alarm can be issued. By monitoring the fault alarm information, the fault situation of the temperature control end 103 can be discovered and handled in time.

[0028] The temperature control terminal 103 is used to read multiple real-time temperature data and adjust and control the heat dissipation operation in the power cabinet according to the temperature adjustment threshold; wherein, the heat dissipation control terminal includes a heat dissipation device, an intelligent control unit, and a sensor; the sensor is used to generate real-time temperature data and transmit it to the intelligent control unit; specifically, the real-time temperature data is obtained through real-time monitoring by the sensor unit, and each real-time temperature data is accompanied by a specific identifier corresponding to an area inside the power cabinet.

[0029] The intelligent control unit is configured to read the plurality of real-time temperature data, and when the real-time temperature data is higher than the temperature adjustment threshold, control the heat dissipation device to start a cooling operation for the area corresponding to the real-time temperature data; and when the real-time temperature data is lower than the temperature adjustment threshold, control the heat dissipation device to stop the cooling operation for the area corresponding to the real-time temperature data;

[0030] The intelligent control unit is further configured to generate the temperature monitoring data and the device status data according to the real-time temperature data, and transmit the data to the server 101 via the network 102 .

[0031] Specifically, the intelligent control unit can be a microcontroller, which can be a single-chip microcomputer system that integrates a central processing unit (CPU), memory (RAM, ROM, flash memory, etc.), input / output interface (GPIO, serial port, SPI, I2C, etc.), timer / counter, analog-to-digital converter (ADC), digital-to-analog converter (DAC) and other functions; the intelligent control unit can collect real-time temperature data in real time by connecting to sensors, and based on the collected data, the intelligent control unit can control and adjust the heat dissipation device to achieve the purpose of precise temperature control; the intelligent control unit can also communicate with the server 101 or other devices through various communication interfaces (such as WiFi, Ethernet, Bluetooth, etc.) to achieve remote monitoring, remote control and data transmission; the intelligent control unit can display real-time data, alarm information and operation interface to the user through a built-in user interface or by connecting to an external display device (such as an LCD screen, LED display, etc.).

[0032] It should be noted that this embodiment does not limit the heat dissipation device. Regardless of the structure and connection method, as long as the heat dissipation device can cool the power cabinet area corresponding to the real-time temperature data, it should be within the scope of protection of the present invention. Of course, a specific heat dissipation device can be designed, as shown below:

[0033] Please see further Figure 2-6 The heat dissipation device includes a main frame 1 fixedly connected to the air outlet of the power cabinet, the opposite side of the main frame 1 is fixedly connected to the slide 2, a grid 4 is provided between the slides 2 in the main frame 1, a torsion arm 18 is provided in the slide 2, and one end of the torsion arm 18 is fixedly connected to a heat absorbing plate 19, and the sensor is provided on the heat absorbing plate 19.

[0034] Specifically, the heat absorbing plate 19 can be made of a material with good thermal conductivity, such as copper, aluminum or copper alloy, etc. This application does not impose any specific restrictions. The heat absorbing plate 19 can also be fixed to the heating element by using thermal conductive glue, screws, clamping and welding according to different heating components; the sensor can include a temperature sensor, and each sensor has a specific mark.

[0035] The other end of the torsion arm 18 is fixedly connected to a conductive disc 3, and a fastening rod 17 is fixedly connected to the side of the conductive disc 3 close to the slide groove 2. The fastening rod 17 is clamped in the slide groove 2, and the conductive disc 3 is arranged in a close relationship with the opening of the slide groove 2. The grid plate 4 is clamped between the upper and lower corresponding conductive discs 3, and the grid plates 4 are both clamped at the joints of two adjacent conductive discs 3.

[0036] Specifically, the conductive disc 3 can be tightly fitted on both ends of the grid 4 under the clamping of the fastening rod 17 and the extrusion force of the grid 4. Since the grid 4 is arranged at the fitting position of two adjacent conductive discs 3, a grid 4 is clamped on both sides of each conductive disc 3. While improving the installation stability of the torsion arm 18, it also increases the number of grids 4 that conduct heat with the conductive disc 3, greatly improving the heat dissipation efficiency.

[0037] A positioning groove 5 is provided in the middle of the grid plate 4, and a plurality of the grid plates 4 are connected in series laterally by inserting a positioning rod 6 into the positioning groove 5. Specifically, after the plurality of grid plates 4 are connected in series laterally by means of the positioning rod 6 and the positioning groove 5, it is possible to avoid sudden displacement of one of the grid plates 4, thereby improving the stability of the heat dissipation structure.

[0038] A through rail 7 is provided inside the grid plate 4, and a circulation pipe 8 is fitted on the inner wall of the through rail 7. Specifically, both ends of the circulation pipe 8 are connected to the cooling circulation pump to form a loop. The cooling circulation pump is electrically connected to the intelligent control unit, and the intelligent control unit controls the cooling circulation pump to circulate coolant into the circulation pipe 8; optionally, the cooling circulation pump can be a centrifugal pump or an axial flow pump, and this application does not impose any specific restrictions.

[0039] The heat generated by the power components is absorbed by the heat absorbing disk 19, and the heat is transferred to the conductive disk 3 as a whole through the torsion arm 18 on the outer wall of the heat absorbing disk 19 for heat dissipation. The grid plate 4 is in contact with the outer wall of the conductive disk 3 as a whole, so that the grid plate 4 as a whole absorbs the heat transferred and absorbed by the conductive disk 3. A through rail 7 is provided inside the grid plate 4. While the grid plate 4 conducts heat out through airflow, the heat absorbed by the grid plate 4 is also conducted and absorbed by the grid plate 4 by injecting flowing coolant into the circulation pipe 8 inside the through rail 7.

[0040] It can be understood that during installation, the user can fix the main frame 1 as a whole at the air outlet inside the power cabinet, install the slide 2 and the conductive disc 3 as a whole on the inner side of the main frame 1 for clamping, clamp the grid plate 4 as a whole between the frames of the main frame 1, and press the grid plate 4 as a whole into the overall frame of the main frame 1 through the fastening rod 17 between the conductive disc 3 and the slide 2. A positioning groove 5 is provided inside the grid plate 4, and the positioning rod 6 is inserted into the positioning groove 5 inside the grid plate 4 as a whole, so that the user can arrange and assemble multiple grid plates 4. A torsion arm 18 is provided on the outer wall of the conductive disc 3, and one end of the torsion arm 18 is adjusted so that the heat absorbing plate 19 at one end of the torsion arm 18 is fixed to the power components on the inner wall of the power cabinet;

[0041] During the operation of this system, when the power components inside the power cabinet generate heat during operation, the heat dissipation device will first absorb the heat generated by the power components through the heat-absorbing disk 19. At the same time, the sensor also collects and generates real-time temperature data containing specific identification, and transfers the heat to the conductive disk 3 as a whole through the torsion arm 18 on one side of the heat-absorbing disk 19 for heat dissipation. The grid plate 4 is in contact with the outer wall of the conductive disk 3 as a whole, so that the grid plate 4 absorbs the heat transferred and absorbed by the conductive disk 3 as a whole. Since the main frame 1 is arranged at the air outlet of the power cabinet, the air flow circulating here will pass through the grid plate 4 and take away a large amount of heat. The technical solution of the present application connects all the power components in various areas inside the power cabinet to the grid plate 4 through thermal conduction through the torsion arm 18, which can achieve overall balanced cooling of the power components inside the power cabinet, which is conducive to better controlling the operating temperature of the power components within a reasonable range.

[0042] At the same time, the intelligent control unit continuously obtains the real-time temperature data collected and generated by the sensor. When the real-time temperature data obtained by the intelligent control unit is higher than the temperature adjustment threshold, it means that the power components corresponding to the specific identifiers of the real-time temperature data in the power cabinet have generated a large amount of heat, and then these large amounts of heat will eventually be conducted to two adjacent grid plates 4 through the torsional branch pipe. At this time, the intelligent control unit can control the start of the liquid cooling circulation pump corresponding to the specific identifier according to the specific identifier in the real-time temperature data, and the coolant can start to circulate on the two grid plates 4 to pre-cool the grid plates 4 in advance. The above technical solution achieves rapid and accurate cooling of the main heat-generating power components in the power cabinet, avoiding the situation where individual main heating units are in an overheated state for a long time due to their limited impact on the overall temperature of the power cabinet due to their small number and are not easy to be detected, and thus individual main heating units are in an overheated state for a long time and are easily damaged.

[0043] Further, please also refer to Figure 9 As shown in the figure, the outer wall of the torsion arm 18 is spirally wound with a first reinforcing rib 20, and the outer wall of the first reinforcing rib 20 is fixedly connected with a second reinforcing rib 21. Specifically, since the layout of power components inside the power cabinet is often more complicated, the position of the torsion arm 18 needs to be adjusted accordingly. During the adjustment process, the torsion arm 18 may not be able to be stably shaped. Therefore, a first reinforcing rib 20 is provided on the outer wall of the torsion arm 18. After the torsion arm 18 is adjusted to a corresponding angle as a whole, the torsion arm 18 is fixed by the first reinforcing rib 20 and the second reinforcing rib 21, so that the adjusted angle of the torsion arm 18 is fixed.

[0044] Further, please also refer to Figure 7-8 As shown in the figure, the portion of the circulation pipe 8 located outside the grid plate 4 is also provided with a first ring 9, a second ring 10 is provided below the first ring 9, and a third ring 11 is provided between the first ring 9 and the second ring 10, and the interiors of the first ring 9, the second ring 10 and the third ring 11 are all connected to the circulation pipe 8.

[0045] Specifically, the number of the first ring 9, the second ring 10 and the third ring 11 is two groups, and the two groups of the first ring 9, the second ring 10 and the third ring 11 are arranged in an axisymmetric state with respect to the vertical central axis of the flow tube 8.

[0046] The outer wall of the first collar 9 is fixedly connected to a first branch pipe 12, the outer wall of the second collar 10 is fixedly connected to a second branch pipe 13, the outer wall of the third collar 11 is fixedly connected to a third branch pipe 14, and the third branch pipe 14 is interconnected with the interiors of the first branch pipe 12 and the second branch pipe 13. It can be understood that through the above arrangement, the heat dissipation area of ​​the circulation pipe 8 on the outer side of the grid plate 4 is greatly increased, and more heat can be taken away by air convection.

[0047] Furthermore, the outer wall of the circulation tube 8 is provided with a heat dissipation copper ring 15, and the heat dissipation copper ring 15 is arranged on the outer wall of the grid 4, the outer wall of the heat dissipation copper ring 15 is provided with a connecting copper ring 16, and the connecting copper ring 16 is sleeved on the outer wall of the circulation tube 8. Specifically, the heat dissipation copper ring 15 and the connecting copper ring 16 are provided on the outer wall of the circulation tube 8 to assist the first ring 9, the second ring 10 and the third ring 11 in the overall heat dissipation of the circulation tube 8.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
