[0060] In addition, it should be noted that Figure 1What is shown is only one application environment provided by the present disclosure. In actual application, other application environments may also be included.

[0061] In the embodiments of this specification, the computing end 01 and the control end 02 may be directly or indirectly connected via wired or wireless communication, and this disclosure does not limit this.

[0062] Figure 2 is a flow chart showing a fan control method of a heat dissipation system according to an exemplary embodiment. Figure 2 As shown, the fan control method of the heat dissipation system includes the following:

[0063] Step S201: Obtain the current air inlet temperature value corresponding to the cooling system.

[0064] In the disclosed embodiment, the heat dissipation system includes multiple air inlets and multiple fan control units. A temperature collection unit is provided corresponding to each air inlet to collect the temperature of the corresponding air inlet, and each fan control unit is connected to multiple temperature collection units. Figure 3 is a basic block diagram of a fan control unit according to an exemplary embodiment. Figure 3 As shown, assuming that the cooling system has n air inlets, n temperature acquisition units are set to collect the temperature of each air inlet. Assuming that the cooling system has m fan control units, each fan control unit controls the rotation of one or more fans in the fan group, and each fan control unit is connected to n temperature acquisition units. Each fan control unit has a unique address, ranging from 0 to m-1. The cooling system uses an operation unit, which mounts m fan control units.

[0065] In a possible implementation of the embodiment of the present disclosure, the obtaining of the current air inlet temperature value corresponding to the heat dissipation system may include:

[0066] Step S2011: temperature data corresponding to each of the plurality of air inlets are obtained by respectively collecting temperature data from the plurality of air inlets using a plurality of temperature collecting units.

[0067] In the disclosed embodiment, each temperature acquisition unit collects the temperature at one air inlet, and the multiple temperature acquisition units collect the temperature of multiple air inlets respectively. The multiple temperature acquisition units collect the temperature of multiple air inlets at the same time according to a preset time interval, obtain the temperature data corresponding to each of the multiple air inlets, and transmit the real-time collected temperature data corresponding to each of the multiple air inlets to multiple fan control units. Optionally, the temperature acquisition unit can select a PT1000 platinum resistance temperature sensor to collect temperature. The resistance of PT1000 is different at different temperatures. Through this feature, the sampling temperature can be obtained by comparing the current resistance of PT1000 with the PT1000 graduation table.

[0068] Step S2012: Analyze and filter the temperature data corresponding to the multiple air inlets through multiple fan control units to obtain multiple candidate temperature values, including the highest air inlet temperature value filtered out by each fan control unit from the temperature data corresponding to the multiple air inlets.

[0069] In the disclosed embodiment, each fan control unit performs data analysis and data screening on the temperature data corresponding to each of the n air inlets to obtain the maximum value among the n temperature data, and determines the maximum value as the highest air inlet temperature value screened by the fan control unit. The m fan control units obtain a total of m highest air inlet temperature values, i.e., m candidate temperature values. Optionally, the fan control unit is connected to the operation unit via an RS485 serial communication protocol, and the m fan control units send the m candidate temperature values ​​to the operation unit via the RS485 serial communication protocol. Each time multiple fan control units receive the temperature data corresponding to each of the n air inlets, data analysis and data screening are performed to obtain the current m candidate temperature values.

[0070] Step S2013: Determine the maximum value among the multiple candidate temperature values ​​as the current air inlet temperature value.

[0071] In the embodiment of the present disclosure, each time the computing unit receives m candidate temperature values, it screens the m candidate temperature values ​​and determines the maximum value thereof as the current air inlet temperature value. The current air inlet temperature value is recorded as .

[0072] Based on the above, it can be known that in the embodiment of the present disclosure, by respectively collecting temperatures of multiple air inlets through multiple temperature collection units, the temperature data corresponding to each of the multiple air inlets can be obtained, making the collected data richer; by respectively analyzing and screening the temperature data corresponding to each of the multiple air inlets through multiple fan control units, the errors caused by the data analysis and screening process are reduced, and the data accuracy is improved.

[0073] Step S202: Determine a target temperature rise value and a target working environment temperature value, wherein the target temperature rise value indicates a maximum temperature rise value set for the target device, and the target working environment temperature value indicates a maximum working environment temperature value set for the target device, and the target device is a device in a device that is cooled by a cooling system.

[0074] In the embodiment of the present disclosure, the heat dissipation system is the heat dissipation system of the charging pile, and the target device is the device associated with the charging line in the charging pile. The target temperature rise value and the target working environment temperature value are specified in the standard, and the target temperature rise value and the target working environment temperature value can directly apply the specified value. The target temperature rise value is recorded as , the target working environment temperature is recorded as .

[0075] Step S203: Determine a target temperature difference between the target working environment temperature value and the current air inlet temperature value.

[0076] In the embodiment of the present disclosure, the target temperature difference between the target working environment temperature value and the current air inlet temperature value can be calculated by the following formula (1):

[0077] (1)

[0078] In formula (1), is the target temperature difference, is the target working environment temperature value, The current air inlet temperature.

[0079] Step S204: when the target temperature difference is greater than zero, a fan speed threshold corresponding to the cooling system is determined based on the relationship between the target temperature difference and the target temperature rise value, where the fan speed threshold represents the maximum speed of the fan of the current cooling system.

[0080] In an optional embodiment, determining a fan speed threshold corresponding to the heat dissipation system based on the magnitude relationship between the target temperature difference and the target temperature rise value may include:

[0081] Step S2041: when the target temperature difference is not greater than the target temperature rise value, the fan speed threshold is calculated according to the current air inlet temperature value, the target temperature rise value, the target working environment temperature value and the maximum speed of the fan.

[0082] In the embodiment of the present disclosure, the target temperature difference is not greater than the target temperature rise value, that is, In this case, the fan speed threshold can be adjusted linearly. The fan speed threshold is calculated based on the current air inlet temperature, target temperature rise, target operating environment temperature, and the rated maximum speed of the fan, including:

[0083] The difference between the target temperature rise value and the target working environment temperature value is added to the current air inlet temperature value to obtain a first parameter; the ratio of the first parameter to the target temperature rise value is determined as a second parameter; the second parameter is multiplied by the rated maximum speed to obtain a fan speed threshold.

[0084] In the embodiment of the present disclosure, the above calculation process can be calculated by the following formula (2):

[0085] (2)

[0086] In formula (2), is the fan speed threshold, is the target temperature rise value, is the target working environment temperature value, is the current air inlet temperature value, is the rated maximum speed.

[0087] Based on the above, it can be known that in the embodiment of the present disclosure, the ratio of the first parameter obtained by adding the difference between the target temperature rise value and the target working environment temperature value and the current air inlet temperature value to the target temperature rise value is determined as the second parameter, and the second parameter is multiplied by the rated maximum speed to obtain the fan speed threshold. The speed threshold that matches the operating condition of the fan with the current equipment can be determined based on the target temperature rise value, the target working environment temperature value and the current air inlet temperature value.

[0088] Step S2042: when the target temperature difference is greater than the target temperature rise value, the fan speed threshold is determined to be zero.

[0089] In the disclosed embodiment, the target temperature difference is greater than the target temperature rise value, that is, In the case of .

[0090] Based on the above, it can be known that in the embodiment of the present disclosure, by calculating the fan speed threshold based on the current air inlet temperature value, the target temperature rise value, the target working environment temperature value and the maximum speed of the fan when the target temperature difference is not greater than the target temperature rise value, the speed threshold of the fan that matches the working condition of the current device can be determined; by determining the fan speed threshold to be zero when the target temperature difference is greater than the target temperature rise value, the fan speed threshold can be set to zero when the current heat dissipation demand is low, and the heat dissipation by the fan can be stopped, thereby avoiding unnecessary power consumption of the cooling system.

[0091] Step S205: Control the fan speed based on the fan speed threshold.

[0092] In an optional embodiment, the above calculation process may be completed by a computing unit, and the computing unit feeds back the calculated fan speed threshold to m fan control units, and the fan control unit controls the fan speed based on the fan speed threshold. The control process includes:

[0093] When the rotation speed of the fan exceeds the fan rotation speed threshold, the rotation speed of the fan is controlled to be reduced to not exceed the fan rotation speed threshold.

[0094] In the disclosed embodiment, when controlling the speed of the fan, the fan speed threshold does not represent the speed to which the current fan should be adjusted, but means that the speed of the current fan should not exceed the speed value corresponding to the fan speed threshold. The heat dissipation of the heat dissipation system is proportional to the speed of the fan. According to the current state of the device reflected by the current air inlet temperature value, the target temperature rise value, and the target working environment temperature value, the fan speed does not exceed the fan speed threshold to meet the heat dissipation requirements of the current device. If the fan speed is higher than the fan speed threshold, unnecessary heat dissipation power consumption and noise will be caused. Therefore, when the fan speed does not exceed the fan speed threshold, the method disclosed in this embodiment does not affect the basic speed regulation logic of the fan. When the fan speed exceeds the fan speed threshold, the fan speed is controlled to be reduced to not exceed the fan speed threshold.

[0095] Based on the above, it can be known that in the embodiment of the present disclosure, by controlling the fan speed to reduce to not more than the fan speed threshold when the fan speed exceeds the fan speed threshold, the fan speed can be matched with the current operating condition of the device, thereby avoiding unnecessary fan power consumption and noise caused by excessively high fan speed.

[0096] In an optional embodiment, if Figure 4 As shown, the method also includes:

[0097] Step S401: when the target temperature difference is not greater than zero, the rated maximum rotation speed of the fan is determined as the fan rotation speed threshold.

[0098] In the embodiment of the present disclosure, the target temperature difference is not greater than zero, that is, In the case of the fan speed threshold, it indicates that the current device needs to dissipate heat as quickly as possible, so the rated maximum speed of the fan is determined as the fan speed threshold to increase the fan speed adjustment range.

[0099] Step S402: Control the fan speed not to exceed a fan speed threshold.

[0100] In the disclosed embodiment, since the device needs to dissipate a large amount of heat, the fan speed can be adjusted to a fan speed threshold, that is, a rated maximum speed, to achieve rapid heat dissipation.

[0101] Based on the above, it can be seen that in the embodiment of the present disclosure, by determining the rated maximum speed of the fan as the fan speed threshold when the target temperature difference is not greater than zero, the speed adjustment range of the fan can be increased, so that the cooling system can promptly remove the generated heat through a higher wind speed.

[0102] In a specific embodiment, the implementation process of the present disclosure is as follows Figure 5 As shown, when the charging pile starts charging, the temperature acquisition unit collects the temperatures of n air inlets, selects the highest temperature value as the current air inlet temperature value K1, and combines the input target temperature rise value K2 and the target working environment temperature value K3 to determine the current state of the charging pile. When the difference between the target working environment temperature value K3 and the current air inlet temperature value K1 is greater than 0, determine whether the difference is greater than the target temperature rise value K2. When the difference is greater than the target temperature rise value K2, the fan speed threshold (maximum fan speed) is determined to be 0. When the difference is not greater than the target temperature rise value K2, the fan speed threshold is linearly adjusted according to the current air inlet temperature value K1, the target temperature rise value K2, the target working environment temperature value K3 and the rated maximum speed M, that is, the maximum speed is linearly adjusted. The linear adjustment method is based on the above formula (2) Obtained. When the difference between the target working environment temperature value K3 and the current air inlet temperature value K1 is not greater than 0, the fan speed threshold (maximum fan speed) is determined as the rated maximum speed, that is, full speed. Subsequently, the fan speed is controlled not to exceed the fan speed threshold according to the fan speed threshold. During the charging process of the charging pile, the above process is repeated at regular intervals until the charging pile stops charging.
