[0042] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of the technical solutions of this application, but not all of them. Based on the embodiments described in this application document, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the technical solutions of this application.

[0043] It should be noted that the term "multiple" in the embodiments of the present application refers to two or more. In addition, it should be understood that in the description of the embodiments of the present application, terms such as "first" and "second" are used only for the purpose of distinguishing descriptions and should not be understood as indicating or implying relative importance or order.

[0044] In order to make the purpose, technical solutions and advantages of this application clearer, this application will be further described in detail below with reference to the accompanying drawings.

[0045] First, the application scenarios of the embodiments of the present application are introduced.

[0046] like Figure 1 As shown, the heat dissipation control solution provided in the embodiments of the present application can be applied to an air-cooled heat dissipation system (hereinafter referred to as a heat dissipation system). The air-cooled heat dissipation system may include an electronic fan and at least one component. The at least one component may include, but is not limited to, a motor, a motor controller, a hydraulic oil radiator, and other components.

[0047] The heat dissipation system can be installed on engineering machinery equipment, vehicles, aircraft and other equipment. Engineering machinery equipment usually operates in dangerous environments, including hot and humid environments, mountainous areas, and dusty environments. In particular, electric engineering machinery equipment has strict requirements on the operating temperature of motors, batteries and motor controllers. Therefore, electric engineering machinery equipment requires a stable and reliable heat dissipation system so that each component in the electric engineering machinery equipment can operate within a suitable temperature range. Similarly, the operation of vehicles and aircraft also has high requirements for the temperature of components. It is of great significance to provide electric engineering machinery equipment, vehicles, and aircraft with a reliable heat dissipation system so that each internal component can operate within a suitable temperature range.

[0048] In the related art, when the heat dissipation system is working, the electronic fan runs at full speed, which results in low energy utilization, high energy consumption of the battery powering the electronic fan, and shortened battery life.

[0049] In view of this, the present application provides a heat dissipation control method and related equipment, which can have good heat dissipation effect and improve energy utilization.

[0050] Figure 2 According to an exemplary embodiment, a heat dissipation control method is shown, which can be applied to a heat dissipation system. The method may include the following steps:

[0051] Step S201: obtaining the current temperature of at least one component in the heat dissipation system.

[0052] In specific implementations, the cooling system may include, but is not limited to, a motor, a motor controller, a hydraulic oil radiator, and other components with operating temperature requirements. The at least one component in the cooling system in the embodiments of the present application may be part or all of the components in the cooling system. Optionally, the at least one component may include a motor, a motor controller, and a hydraulic oil radiator. The cooling system may obtain the temperature of the at least one component in real time or periodically.

[0053] Step S202: If the temperature of the at least one component meets a preset condition, obtain the current ambient temperature.

[0054] In a specific implementation, the heat dissipation system may determine whether the temperature of the at least one component meets a preset condition. If the temperature of the at least one component meets the preset condition, it may indicate that the electronic fan is currently required to operate. The heat dissipation system may obtain the current ambient temperature and perform the operation of step S203 to control the operation of the electronic fan. If the temperature of the at least one component does not meet the preset condition, it may indicate that the electronic fan is currently not required to operate. The heat dissipation system may re-execute the operations of steps S201-S203.

[0055] Optionally, the preset condition may include the temperature of any one of the at least one component being greater than or equal to a corresponding temperature threshold. For example, the at least one component may include a motor, a motor controller, or a hydraulic radiator. The preset condition may include one or more of the following: Condition 1: The temperature of the motor is greater than or equal to a first temperature threshold; Condition 2: The temperature of the motor controller is greater than or equal to a second temperature threshold; Condition 3: The temperature of the hydraulic radiator is greater than or equal to a third temperature threshold.

[0056] Step S203 : determining a duty cycle of a control signal of the electronic fan based on the current ambient temperature and a distance coefficient between each of the at least one component and the electronic fan.

[0057] In a specific implementation, the distance coefficient between each component and the electronic fan is determined based on the distance between each component and the electronic fan. The heat dissipation system can use the current ambient temperature and the distance coefficient between each of the at least one component and the electronic fan to determine the duty cycle of the electronic fan control signal. Based on this duty cycle, the electronic fan control signal is generated and controlled. In actual application scenarios, when the duty cycle of the electronic fan control signal is 1, the electronic fan is operating at full speed. By adjusting the duty cycle of the electronic fan control signal, the electronic fan speed can be adjusted.

[0058] The electronic fan rotates to provide a cooling effect for the heat dissipation system. Adjusting the operating state of the electronic fan, taking into account the distance coefficient between the at least one component and the electronic fan and the current ambient temperature, can ensure the heat dissipation effect of the heat dissipation system, reduce the power consumption of the electronic fan, and improve the energy utilization rate of the battery powering the electronic fan.

[0059] In one possible implementation, the heat dissipation system may perform the following process when determining the duty cycle of the control signal of the electronic fan based on the current ambient temperature and the distance coefficient between the at least one component and the electronic fan:

[0060] The heat dissipation system can determine the target ambient temperature influence coefficient corresponding to the current ambient temperature based on the correspondence between the preset ambient temperature and the ambient temperature influence coefficient; the heat dissipation system can determine the duty cycle of the control signal of the electronic fan based on the target ambient temperature influence coefficient, the distance coefficient between each component of the at least one component and the electronic fan, and the current temperature of each component.

[0061] During specific implementation, the heat dissipation system may store a correspondence between a preset ambient temperature and an ambient temperature influence coefficient. In some examples, the correspondence between the preset ambient temperature and the ambient temperature influence coefficient may be a preset correspondence table. The heat dissipation system may query the ambient temperature influence coefficient corresponding to the current ambient temperature by looking up the table. In other examples, the correspondence between the preset ambient temperature and the ambient temperature influence coefficient may be a preset function. The heat dissipation system may calculate the function value corresponding to the current ambient temperature, which is the ambient temperature influence coefficient corresponding to the current ambient temperature. For ease of introduction, the ambient temperature influence coefficient corresponding to the current ambient temperature is referred to as the target ambient temperature influence coefficient below.

[0062] In one possible implementation, please combine Figure 3 , Figure 3 The distance between components in the cooling system and the electronic fan is exemplified. Optionally, the distance between each of the at least one component and the electronic fan can be the linear distance between the component and the electronic fan along the X-axis. The X-axis of the electronic fan is perpendicular to the mounting surface of the electronic fan. The linear distance between a component and the electronic fan along the X-axis can be understood as the minimum distance between the component and the electronic fan along the X-axis.

[0063] It should be noted that although Figure 3 The distances between the hydraulic oil radiator, motor controller, motor and other components and the electronic fan are shown in the figure. Figure 3 The distance between the components and the electronic fan is merely illustrative and does not constitute a specific limitation on the relative positional relationships between the components, nor does it constitute a specific limitation on at least one component in the aforementioned heat dissipation system. It is understood that the at least one component in the heat dissipation system may include, but is not limited to, a hydraulic oil radiator, a motor controller, and a motor, and may also include other components, which are not specifically limited in this embodiment of the present application. The distance between the motor and the electronic fan is denoted as L1, the distance between the motor controller and the electronic fan is denoted as L2, and the distance between the hydraulic oil radiator and the electronic fan is denoted as L3.

[0064] In actual application scenarios, the positions of the components in the heat dissipation system are fixed. Therefore, the distance between each of the at least one component and the electronic fan is also fixed, and thus the distance coefficient of each of the at least one component is also fixed. The heat dissipation system may pre-store the distance coefficient of each of the at least one component.

[0065] Optionally, the greater the distance between each of the at least one component and the electronic fan, the greater the distance coefficient of the component.

[0066] The heat dissipation system may calculate a duty cycle of the control signal of the electronic fan by using the target ambient temperature influence coefficient, a distance coefficient between each of the at least one component and the electronic fan, and a current temperature of each component.

[0067] In one possible implementation, the heat dissipation system can calculate the duty cycle of the electronic fan control signal based on the relationship (referred to as the first relationship) between the pre-configured duty cycle of the electronic fan and the temperature coefficient of each component in the at least one component, and the distance coefficient of each component and the target ambient temperature influence coefficient. Optionally, the mathematical expression of the first relationship can be Wherein, α represents the target ambient temperature influence coefficient, n represents the total number of components of the at least one component, P m Characterizes the distance coefficient between the mth component and the electronic fan. m Characterizes the temperature coefficient of the mth component. Where m is a positive integer, and the value of m can range from 1 to n.

[0068] In one possible design, any one of the at least one component has a corresponding first temperature and a second temperature. The first temperature of the component represents the lowest temperature at which the electronic fan is triggered to start (and therefore run). In other words, if the current temperature of the component is greater than or equal to the first temperature, the electronic fan can be triggered to run. In actual application scenarios, the first temperature of the component is preconfigured.

[0069] The second temperature of the component represents the temperature of the component that triggers the electronic fan to operate at full speed. In other words, if the current temperature of the component is greater than or equal to the second temperature of the component, the electronic fan can be triggered to operate at full speed. In actual application scenarios, the second temperature of the component is pre-configured.

[0070] Optionally, the current temperature of any one of the components, the preset first temperature and second temperature corresponding to any one of the components, and the temperature coefficient of any one of the components satisfy the following relationship:

[0071]

[0072] Among them, T m Characterize the temperature coefficient of any component m, t sm Characterizes the current temperature of any component m, t dm Characterize the first temperature corresponding to any one component m, t jm Characterizes a second temperature corresponding to any one component m.

[0073] The heat dissipation system may calculate a temperature coefficient for each component of the at least one component based on the first temperature and the second temperature corresponding to each component and the current temperature of each component. The heat dissipation system may calculate a duty cycle of a control signal for the electronic fan based on a distance coefficient between each component of the at least one component and the electronic fan, the temperature coefficient of each component, and a target ambient temperature influence coefficient.

[0074] Figure 4 According to an exemplary embodiment, a heat dissipation control method is shown, which can be applied to a heat dissipation system and executed by a heat dissipation system controller. The method may include the following steps:

[0075] Step S401: obtaining the current temperature of at least one component in the heat dissipation system.

[0076] In a specific implementation, in this embodiment of the present application, at least one component of the heat dissipation system includes a motor, a motor controller, and a hydraulic oil radiator. In step S401, the heat dissipation system controller may obtain the current temperature of the motor, the current temperature of the motor controller, and the current temperature of the hydraulic oil radiator. The heat dissipation system controller may obtain the current temperature of each of the at least one component using a temperature detection circuit or a temperature sensor.

[0077] Step S402, determining whether the electronic fan needs to be turned on, if so, executing step S403 next, if not, executing step S401 next.

[0078] The heat dissipation system controller can determine whether to turn on the electronic fan according to the temperature of each component in the at least one component. Turning on the electronic fan in this application also means starting the electronic fan, that is, making the electronic fan run.

[0079] The heat dissipation system controller can determine whether the temperature of each component of at least one component meets the preset conditions to determine whether the electronic fan needs to be turned on. The preset conditions may include:

[0080] Condition 1: The temperature of the motor is greater than or equal to the first temperature threshold;

[0081] Condition 2: The temperature of the motor controller is greater than or equal to the second temperature threshold;

[0082] Condition 3: The temperature of the hydraulic oil radiator is greater than or equal to a third temperature threshold.

[0083] If the current temperature of the motor is greater than or equal to a first temperature threshold, i.e., condition 1 is satisfied, the cooling system controller may determine that the temperature of the at least one component satisfies a preset condition. Similarly, if the temperature of the motor controller is greater than or equal to a second temperature threshold, i.e., condition 2 is satisfied, the cooling system controller may determine that the temperature of the at least one component satisfies a preset condition. Similarly, if the temperature of the hydraulic oil radiator is greater than or equal to a third temperature threshold, i.e., condition 3 is satisfied, the cooling system controller may determine that the temperature of the at least one component satisfies a preset condition.

[0084] Conversely, if the current temperature of the motor is less than the first temperature threshold, the current temperature of the motor controller is less than the second temperature threshold, and the current temperature of the hydraulic oil radiator is less than the third temperature threshold, the cooling system controller may determine that the temperature of the at least one component does not meet the preset condition, indicating that it is not necessary to turn on the electronic fan, and then execute step S401 to re-acquire the current temperature of the at least one component in the cooling system.

[0085] Optionally, the first temperature threshold may be 70°C, the second temperature threshold may be 50°C, and the third temperature threshold may be 55°C.

[0086] If the heat dissipation system controller determines that the temperature of the at least one component meets the preset condition, it may determine that the electronic fan needs to be turned on, and the next step is to execute step S403.

[0087] Step S403: Acquire the current ambient temperature.

[0088] The heat dissipation system may include a temperature sensor for collecting ambient temperature. The heat dissipation system controller may receive the ambient temperature collected by the temperature sensor. Alternatively, the heat dissipation system controller may control the temperature sensor to collect the ambient temperature.

[0089] Step S404 : determining a duty cycle of a control signal of the electronic fan based on the current ambient temperature, the distance coefficient of each component in the at least one component, and the current temperature.

[0090] In a specific implementation, the heat dissipation system controller determines the ambient temperature influence coefficient corresponding to the current ambient temperature, ie, the target ambient temperature influence coefficient α, by looking up a table or other means. The heat dissipation system controller may calculate the temperature coefficient of each component in at least one component.

[0091] For example, the cooling system controller may calculate the temperature coefficient of the motor based on the current temperature of the motor, the first temperature corresponding to the motor, and the second temperature corresponding to the motor. The temperature coefficient of the motor and the current temperature of the motor, the first temperature corresponding to the motor, and the second temperature corresponding to the motor may conform to the following relationship: Among them, T1 represents the temperature coefficient of the motor, t s1 Represents the current temperature of the motor, t d1 Characterize the first temperature corresponding to the motor, t j1 Characterizes the second temperature corresponding to the motor.

[0092] Similarly, the cooling system controller can calculate the temperature coefficient of the motor controller based on the current temperature of the motor controller, the first temperature corresponding to the motor controller, and the second temperature. The temperature coefficient of the motor controller and the current temperature of the motor, the first temperature corresponding to the motor controller, and the second temperature can conform to the following relationship: Among them, T2 represents the temperature coefficient of the motor controller, t s2 Represents the current temperature of the motor controller, t d2 Characterize the first temperature corresponding to the motor controller, t j2 Characterizes a second temperature corresponding to the motor controller.

[0093] Similarly, the cooling system controller can calculate the temperature coefficient of the hydraulic oil radiator based on the current temperature of the hydraulic oil radiator, the first temperature and the second temperature corresponding to the hydraulic oil radiator. The temperature coefficient of the hydraulic oil radiator and the current temperature of the hydraulic oil radiator, the first temperature and the second temperature corresponding to the hydraulic oil radiator can conform to the following relationship: Among them, T3 represents the temperature coefficient of the hydraulic oil radiator, t s3 Represents the current temperature of the hydraulic oil radiator, t d3 Characterize the first temperature corresponding to the hydraulic oil radiator, t j3 Characterizes the second temperature corresponding to the hydraulic oil radiator.

[0094] Please combine Figure 3 The distance between the motor and the electronic fan is denoted as L1, and the motor's distance coefficient P1 is related to distance L1. The distance between the motor controller and the electronic fan is denoted as L2, and the motor controller's distance coefficient P2 is related to distance L2. The distance between the hydraulic oil radiator and the electronic fan is denoted as L3, and the hydraulic oil radiator's distance coefficient is related to distance L3.

[0095] The cooling system controller can calculate the duty cycle of the electronic fan control signal based on the pre-stored motor distance coefficient P1, motor controller distance coefficient P2, hydraulic oil radiator distance coefficient P3, motor temperature coefficient T1, motor controller temperature coefficient T2, hydraulic oil radiator temperature coefficient T3 and target ambient temperature influence coefficient α. For example, the duty cycle of the electronic fan control signal is

[0096] It should be noted that the cooling system controller can obtain the duty cycle of the electronic fan control signal through one or more calculation processes, and this application does not impose too many restrictions on this. Optionally, the temperature coefficient of each component in at least one component can be used as an intermediate calculation quantity.

[0097] Based on the same technical concept, the embodiment of the present application provides a controller such as Figure 5 As shown, the controller may include a processor 501 and a memory 502, and the processor 501 and the memory 502 are connected via a bus 503. The processor 501 may be connected to the electronic fan controller and send a duty cycle signal to the electronic fan controller, so that the electronic fan controller generates a control signal for the electronic fan according to the duty cycle represented by the received duty cycle signal.

[0098] The memory 502 stores a computer program, and the processor 501 performs the following operations according to the computer program:

[0099] Obtaining a current temperature of at least one component in the cooling system;

[0100] If the temperature of the at least one component meets a preset condition, obtaining the current ambient temperature;

[0101] The duty cycle of the control signal of the electronic fan is determined based on the current ambient temperature and a distance coefficient of each component of the at least one component, wherein the distance coefficient of each component is determined based on the distance between each component and the electronic fan.

[0102] In one possible implementation, when the processor 501 performs the operation of determining the duty cycle of the control signal of the electronic fan based on the current ambient temperature and the distance coefficient between the at least one component and the electronic fan, the processor 501 specifically performs the following operations:

[0103] Determining a target ambient temperature influence coefficient corresponding to the current ambient temperature based on a correspondence between a preset ambient temperature and an ambient temperature influence coefficient;

[0104] A duty cycle of a control signal of the electronic fan is determined based on the target ambient temperature influence coefficient, a distance coefficient between each of the at least one component and the electronic fan, and a current temperature of each component.

[0105] In one possible implementation, when the processor 501 performs the operation of determining the duty cycle of the control signal of the electronic fan based on the target ambient temperature influence coefficient, the distance coefficient between each of the at least one component and the electronic fan, and the current temperature of each component, the processor 501 specifically performs the following operations:

[0106] For any one of the at least one component, based on the current temperature of the any one component, determining a temperature coefficient corresponding to each component; and using a product of the target ambient temperature influence coefficient, a distance coefficient between the any one component and the electronic fan, and the temperature coefficient corresponding to the any one component as a duty cycle parameter corresponding to the any one component;

[0107] The duty cycle of the control signal of the electronic fan is determined according to the duty cycle parameters corresponding to the components.

[0108] In a possible implementation, when the processor 501 performs the operation of determining the temperature coefficient corresponding to each component based on the current temperature of any one component, the processor 501 specifically performs the following:
