[0002] High-power charging equipment will produce certain performance losses during operation, and these losses mainly come from its charging module. At present, the heat dissipation methods of charging modules are mainly divided into two types: air cooling and liquid cooling, and air cooling is the current mainstream method. For high-power charging equipment that uses air cooling, an exhaust fan must be installed in the cabinet to discharge the heat generated by the charging module out of the cabinet, and to attract external low-temperature air into the cabinet by forming negative pressure, ensuring that the internal components of the charging equipment operate at a suitable working temperature.

[0003] However, there are some problems with traditional air cooling. For example, in conventional charging equipment, fans are often operated in series. When the charging equipment is started, all cooling fans are turned on at the same time and run continuously at the rated speed, which will cause greater noise pollution. When not fully loaded, the cooling air volume often far exceeds the actual demand, resulting in unnecessary energy waste. Summary of the invention

[0047] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0048] Figure 1 A flowchart of a method for controlling heat dissipation of a charging device provided in an embodiment of the present application. Figure 1 As shown, the heat dissipation control method for a charging device provided in an embodiment of the present application may include:

[0049] S101. After receiving a start command of a charging device, obtain the external environment temperature of the charging device cabinet, the actual output power and the rated output power of the charging device.

[0050] First combine Figure 2 Introduce the structure of the charging equipment cabinet. Figure 2 The schematic diagram of the structure of a charging equipment cabinet in the prior art provided in the embodiment of the present application, wherein the leftmost side is the air inlet of the charging equipment cabinet, and a sensor, such as a temperature sensor, is provided at the air inlet to detect the ambient temperature outside the charging equipment cabinet. The charging module is a charging device, such as Figure 2 As shown, the charging equipment cabinet includes multiple charging equipment. The arrows in the figure indicate the flow direction of the wind. The arrow on the left side of the charging equipment indicates the wind entering the charging equipment. The arrow on the right side of the charging equipment indicates the wind after passing through the charging equipment. At this time, the temperature is higher than the temperature of the wind entering the charging equipment. The wind after passing through the charging equipment further enters Figure 2 The multiple cooling fans on the right side of the middle, after being processed by the cooling fans, the temperature in the charging equipment cabinet is reduced. When the charging equipment starts to start, the sensor at the entrance of the charging equipment cabinet starts to detect the ambient temperature, as well as the actual output power and rated output power of the charging equipment.

[0051] S102: Obtain an output load ratio of the charging device according to the actual output power and the rated output power.

[0052] After obtaining the actual output power and rated output power of all charging modules, the output load ratio of the charging modules can be further calculated, and the output load ratio is used to find the corresponding first control strategy in a preset fan operation quantity comparison table.

[0053] S103: Determine a first control strategy according to the external environment temperature and the output load ratio.

[0054] When determining the first control strategy according to the external ambient temperature and the output load ratio, the preset fan operation quantity comparison table is searched, and the preset fan operation quantity comparison table is composed of the external ambient temperature, the output load ratio and the corresponding number of cooling fans turned on, as shown in Table 1. Table 1 is a fan operation quantity comparison table provided in an embodiment of the present application. As shown in Table 1, the table gives a comparison range of multiple ambient temperatures and a range of output load ratios. According to the actual ambient temperature obtained and the output load ratio actually calculated, the corresponding number of cooling fans turned on is obtained by searching in the table, as the first control strategy. The first control strategy is to determine the starting number of cooling fans according to the ambient temperature and the output load ratio in Table 1, and then control the opening of the cooling fans according to the starting number of cooling fans.

[0055] Table 1: Comparison table of fan operation quantity

[0056]

[0057] S104: Control the number of cooling fans in the charging equipment cabinet that are turned on according to the first control strategy.

[0058] After controlling the operation of the cooling fan in the charging equipment cabinet according to the first control strategy, the temperature around the charging module will decrease as the cooling fan works. At this time, it is necessary to further adjust the starting number of the cooling fan to achieve energy saving and environmental protection. In addition, when a large number of cooling fans are turned on, a lot of noise will be generated. Appropriately adjusting the number of cooling fans turned on according to the temperature around the charging equipment can avoid the generation of noise.

[0059] Based on this, in another embodiment of the present application, when the cooling fan in the charging equipment cabinet operates for a first preset period of time according to the first control strategy, there is another control strategy. Figure 3 Make an introduction, Figure 3 A flowchart of another method for controlling heat dissipation of a charging device provided in an embodiment of the present application, combined with Figure 3 As shown, another charging device heat dissipation control method provided in an embodiment of the present application may include:

[0060] S301. After the cooling fan in the charging equipment cabinet operates for a first preset time period according to the first control strategy, the inlet temperature of the cooling fan is obtained.

[0061] To ensure that the charging device and the cooling fan have reached a relatively stable state, after the cooling fan in the charging device cabinet operates for a first preset time period according to a preset first control strategy, the inlet temperature of the current cooling fan is obtained through a temperature sensor arranged at the air inlet of the cooling fan, and this sensor can monitor and record temperature data in real time or at regular intervals. The first preset time period can be 2 minutes or 3 minutes, which is set by those skilled in the art according to the actual situation and is not limited herein.

[0062] S302. Compare the inlet temperature with a preset temperature threshold to obtain a second control strategy.

[0063] After obtaining the inlet temperature, in order to prevent the cooling fan from starting and stopping frequently due to small temperature fluctuations, a temperature hysteresis is set in the embodiment of the present application. This means that when the temperature approaches a certain preset threshold, the system will not immediately change the operating state of the fan, but will wait for the temperature to further change beyond this hysteresis value before making a decision.

[0064] The preset temperature thresholds include a first temperature threshold t1, a second temperature threshold t2, and a third temperature threshold t3. The second control strategy includes:

[0065] Do not start the fan: When the inlet temperature value is not higher than t1, it indicates that the current heat dissipation condition is good and there is no need to start the fan for additional heat dissipation.

[0066] Start one fan: When the inlet temperature is between t1 and t2 (i.e., t1 < t < t2), the system determines that one fan needs to be started to enhance the heat dissipation effect. Start two fans: When the inlet temperature further rises to between t2 and t3 (i.e., t2 < t < t3), the system decides to start two fans to cope with higher heat dissipation requirements. Start three fans: When the temperature exceeds t3, it indicates that the heat dissipation requirement is extremely high, and the system will start all three fans to ensure the normal operation of the device.

[0067] In actual operation, the system will continuously monitor the temperature at the air inlet of the cooling fan and adjust the number and state of the fans in real time according to the above strategy. This dynamic adjustment helps to keep the device within the optimal operating temperature range, while avoiding unnecessary energy consumption and fan wear.

[0068] The following is an example to illustrate the above second control strategy with specific values:

[0069] t1 is set to 30 °C (when the inlet temperature of the cabinet exhaust fan is not higher than this value, the fan does not start);

[0070] t2 is set to 40 °C (when the inlet temperature of the cabinet exhaust fan is between t1 and t2, start 1 fan);

[0071] Set t3 to 50°C (when the inlet temperature of the cabinet exhaust fan is between t2 and t3, start 2 fans; when the temperature is higher than t3, start 3 fans);

[0072] Temperature hysteresis ΔT: Set to 3°C (to prevent the fans from starting and stopping frequently. When the temperature change is less than this value, the number of fans remains unchanged).

[0073] The current inlet temperature T of the cooling fan is 28°C. Since T <= t1 (30°C), no fans are started. When the temperature gradually rises to T = 32°C, at this time, t1 < T < t2 (30°C < 32°C < 40°C), which meets the condition for starting 1 fan. However, due to the temperature hysteresis ΔT (3°C), it is necessary to ensure that the temperature change exceeds this value before adjusting the number of fans. Therefore, the number of fans turned on is not increased. Suppose the temperature continues to rise to T = 34°C (exceeding t1 + ΔT = 33°C), at this time, start 1 fan.

[0074] When the temperature continues to rise to T = 43°C, at this time, t2 < T < t3 (40°C < 43°C < 50°C), which meets the condition for starting 2 fans. But it is also necessary to ensure that the temperature change exceeds the temperature hysteresis ΔT. Suppose the temperature continues to rise to T = 44°C (exceeding t2 + the temperature change amount relative to when starting 1 fan, that is, considering the change from 34°C to 44°C, which meets the condition), at this time, start the 2nd fan. After 2 fans are running, the temperature continues to rise to T = 52°C, at this time, T > t3 (52°C > 50°C), which meets the condition for starting all 3 fans. Since the temperature change has significantly exceeded the temperature hysteresis ΔT (from 44°C to 52°C), the 3rd fan is started.

[0075] Suppose after 3 fans have been running for some time, the temperature starts to drop to T = 49°C. At this time, although the temperature is already lower than t3 (50°C), due to the temperature hysteresis ΔT, the number of fans is not immediately reduced. Wait until the temperature continues to drop to T = 47°C (lower than t3 - ΔT = 47°C), then turn off 1 fan (which fan to turn off specifically can be determined according to the actual situation or strategy. Here, assume the earliest started fan is turned off). Suppose the temperature continues to drop to T = 39°C. At this time, t2 < T < t3 (but it is already lower than the temperature threshold when starting 2 fans before), but due to the existence of the temperature hysteresis, the 2nd fan is not immediately turned off. Wait until the temperature continues to drop to T = 37°C (lower than t2 - ΔT = 37°C), then turn off the 2nd fan. When the temperature drops to T = 29°C (close to but slightly higher than t1, considering the temperature hysteresis, it will not actually trigger the fan to start), keep all fans turned off. When the temperature further drops to T <= t1 (30°C), since it is already within the temperature range where the fans do not start, no operation is required.

[0076] S303: Adjust the number of cooling fans turned on according to the second control strategy.

[0077] According to the second control strategy determined in the previous step, the system will adjust the number of cooling fans turned on, thereby better controlling the temperature inside the charging equipment cabinet by increasing or decreasing the number of fans.

[0078] In an implementation of the embodiment of the present application, before adjusting the number of cooling fans turned on according to the second control strategy, the method further includes:

[0079] It is determined whether the operation time after the last adjustment of the number of fans turned on is greater than the second preset operation time period. If so, the number of fans turned on is adjusted again according to the preset second control strategy.

[0080] Before adjusting the number of cooling fans to be turned on according to the second control strategy, it is necessary to check how much time has passed since the last adjustment. This time will be compared with a preset "second preset operating time period", which can generally be set to 3 minutes, or other time, which is randomly set by technical personnel in this field according to actual conditions. If the operating time since the last adjustment exceeds this preset value, the system will adjust the number of cooling fans to be turned on again according to the currently available second control strategy (based on the previous temperature comparison results). This step is to ensure that the operating status of the cooling fan can adapt to the changing environmental conditions and equipment loads, so as to maintain the best cooling effect.

[0081] The above two embodiments introduce the heat dissipation control method of the charging device, including the cases where the heat dissipation fan is not turned on, partially turned on, and fully turned on. When the heat dissipation fan is not fully turned on, it will cause uneven negative pressure at the rear of the charging device. In order to better discharge the hot air, in one implementation of the embodiment of the present application, an adjustable air guide structure is provided between the air outlet of the charging device and the heat dissipation fan. When the number of the heat dissipation fans changes, the opening angle of the air guide structure changes to make the negative pressure at the rear of the charging device more uniform. Figure 4 As shown, Figure 4 The schematic diagram of the structure of a charging equipment cabinet with an adjustable wind guide structure provided in the embodiment of the present application is as follows: when the cooling fan is partially turned on, the opening angle of the wind guide structure is adjusted according to the number and order of fans turned on; when all fans are fully started, the wind guide structure returns to the initial opening angle. Figure 5 and Figure 6 As shown, Figure 5 This is a structural diagram of a charging equipment cabinet corresponding to the operation of the charging equipment provided in the embodiment of the present application. Figure 6 For Figure 5Schematic diagram of the corresponding air guiding structure angle adjustment.

[0082] The opening angle θ of the air guiding structure adjusts the air flow direction according to the number of operating fans. When t < t1, the fan is not started, and the opening angle θ of the air guiding structure is 90°. When t1 < t < t2, when one fan is started, the opening angle θ of the air guiding structure is 45°. When t2 < t < t3, when two fans are started, the opening angle θ of the air guiding structure is 70°. When t3 < t, when all three fans are started, the opening angle θ of the air guiding structure is 90°. Figure 5 A heat dissipation fan is turned on in the leftmost charging equipment cabinet. At this time, the corresponding opening angle θ of the air guiding structure is as Figure 6 shown in (a) of Figure 5 , θ = 45°; Figure 6 Two heat dissipation fans are turned on in the middle charging equipment cabinet. At this time, the corresponding opening angle θ of the air guiding structure is as Figure 5 shown in (b) of Figure 6 , θ = 70°;

[0083] Figure 5 and Figure 6 When the heat dissipation fans are turned on as shown in the figure, they are turned on from top to bottom in sequence. Similarly, the heat dissipation fans can also be turned on in sequence from bottom to top, as shown in Figure 7 and Figure 8 shown. Figure 7 This is another schematic diagram of the structure of the charging equipment cabinet corresponding to the operation of the charging equipment provided in the embodiment of the present application. Figure 8 is Figure 7 the corresponding schematic diagram of the air guiding structure angle adjustment.

[0084] If the fans are turned on in sequence from top to bottom:

[0085] When t < t1, the fan is not started, and the opening angle θ of the air guiding structure is 90°.

[0086] When t1 < t < t2, when one fan is started, the opening angle θ of the air guiding structure is 125°.

[0087] When t2 < t < t3, when two fans are started, the opening angle θ of the air guiding structure is 160°.

[0088] When t3 < t, when all three fans are started, the opening angle θ of the air guiding structure is 90°. Figure 7 In the left charging equipment cabinet, the lowermost heat dissipation fan is turned on first. At this time, the corresponding opening angle θ of the air guiding structure is as Figure 8 shown in (a) of Figure 7The middle charging equipment cabinet opens the cooling fans at the bottom and the middle. At this time, the corresponding air guide structure opening angle θ is as follows: Figure 8 As shown in (b), the opening angle of the air guide structure is θ = 160°; Figure 7 In the charging equipment cabinet on the right, three cooling fans are turned on. At this time, the corresponding air guide structure is opened at an angle θ as shown in the figure below. Figure 8 As shown in (c), the opening angle of the air guide structure is θ=90°; when the fan is turned on, the opening angle of the air guide structure is θ=90°.

[0089] The above embodiment of the present application provides a method for controlling the heat dissipation of a charging device. First, by calculating the output load ratio, the method can reflect the working intensity of the charging device in real time, thereby avoiding the problem of excessive or insufficient heat dissipation caused by the inability to accurately perceive the device load in the traditional heat dissipation method. Secondly, the first control strategy is formulated in combination with the external ambient temperature and the output load ratio. The method can flexibly respond to the heat dissipation requirements under different environmental conditions. When the ambient temperature is low and the device load is light, by reducing the number of cooling fans turned on, not only the energy consumption is reduced, but also the noise pollution is effectively reduced, and the user experience is improved. When the ambient temperature is high or the device load is heavy, it can ensure that enough fans are turned on to maintain the reasonable stability of the internal temperature of the charging device and ensure the safe and reliable operation of the equipment. In addition, the method also realizes the optimal configuration of heat dissipation resources, avoiding the waste of resources caused by the operation of all fans at rated speed in the traditional heat dissipation method. By accurately controlling the number of cooling fans turned on, the method improves energy utilization efficiency and reduces operating costs while ensuring the heat dissipation effect. Finally, by setting the air guide structure, the pressure at the rear end of the charging device can be guaranteed to be consistent, thereby optimizing the pressure distribution in the cabinet, improving the ventilation uniformity of each charging module in the cabinet and the reliability of the overall equipment.
