Description

Technical Field

[0001] This application relates to the field of compressor heat dissipation control technology, and more specifically, to a heat dissipation control method and related apparatus for an air compressor. Background Technology

[0002] As the power source for core components such as the locomotive braking system and pneumatic control devices, the stable operation of the air compressor directly affects the locomotive's driving safety and operational efficiency. Heat dissipation performance is one of the key factors determining the air compressor's operational stability. During locomotive operation and stationary periods, the male and female rotors of the air compressor generate a large amount of heat through frictional compression of lubricating oil and compressed air. If this heat cannot be effectively dissipated in a timely manner, the exhaust temperature will rise, triggering the temperature protection switch and leading to malfunctions such as failure to operate the air compressor, severely impacting the locomotive's normal operation.

[0003] Currently, air compressors typically employ forced convection using both lubricating oil and cooling air. A motor-driven cooling fan forces air towards the cooler, dissipating heat from the compressed air and lubricating oil outside the unit, thus achieving cooling. However, due to environmental factors, such as high ambient temperatures, the air delivered by the cooling fan is already hot, reducing the temperature difference between the air and the cooler and significantly decreasing heat exchange efficiency. This makes it difficult to quickly remove the large amount of heat generated during operation, resulting in poor heat dissipation and increasing the risk of overheating and malfunction. Therefore, a technical solution to improve the heat dissipation efficiency of air compressors is urgently needed. Summary of the Invention

[0009] In another exemplary embodiment, after controlling the first solenoid valve according to the control switch state and the intake temperature, the method further includes: obtaining the rate of change of the intake temperature; if the rate of change of the intake temperature is lower than the preset expected cooling rate within a preset time period, then controlling the first solenoid valve to increase its opening to increase the flow rate of compressed air delivered to the air amplifier, and generating a heat dissipation alarm.

[0010] In another exemplary embodiment, after controlling the first solenoid valve according to the control switch state and the intake temperature, the method further includes: if the control switch state changes from a closed state to an open state, obtaining the current intake temperature of the air compressor; if the current intake temperature is higher than a preset safety threshold, performing delayed conduction control on the first solenoid valve until the duration of the delayed conduction control reaches a preset delay duration, or the current intake temperature is lower than the preset safety threshold.

[0011] In another exemplary embodiment, the auxiliary heat dissipation device further includes a pressure reducing valve disposed between the first solenoid valve and the air amplifier. The pressure reducing valve is used to reduce the pressure of the compressed air delivered by the air cylinder to a preset pressure before delivering it to the air amplifier.

[0012] According to one aspect of the embodiments of this application, a heat dissipation control device for an air compressor is provided. An auxiliary heat dissipation device is provided on a cooler connected to the air compressor. The auxiliary heat dissipation device includes a temperature sensor, a blower cylinder, a first solenoid valve, and an air amplifier. The auxiliary heat dissipation device is mounted on the surface of the cooler through the mounting surface of the air amplifier. The first solenoid valve is configured to controllably supply or stop supplying compressed air stored in the blower cylinder to the air amplifier. The air amplifier is used to convert the compressed air into a cooling airflow to dissipate heat from the cooler.

[0015] In the technical solution provided by the embodiments of this application, on the one hand, by setting an auxiliary heat dissipation device on the cooler connected to the air compressor, the air amplifier in the auxiliary heat dissipation device can use the Coanda effect to mix the compressed air delivered in the air cylinder with the cooling air to form a high-speed, high-capacity airflow for discharge. This can quickly remove the redundant heat generated during the operation of the air compressor, significantly reduce the exhaust temperature of the equipment, and improve the heat dissipation efficiency of the air compressor, enabling the air compressor to operate normally even in high-temperature environments.

[0018] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments identical to those described in this application. Rather, they are merely examples of apparatuses and methods identical to some aspects of this application as detailed in the appended claims.

[0019] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities can be implemented as application programs, in one or more hardware modules or integrated circuits, or in different models and / or processor devices and / or microcontroller devices.

[0020] The flowcharts shown in the accompanying drawings are merely illustrative and do not necessarily include all content and operations / steps, nor do they necessarily have to be performed in the described order. For example, some operations / steps can be broken down, while others can be combined or partially combined; therefore, the actual execution order may change depending on the specific circumstances.

[0021] It should be noted that "multiple" as mentioned in this application refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0022] First and foremost, it's important to understand that the air compressor is the core pneumatic power source for electric locomotives. Its primary function is to compress atmospheric air to produce high-pressure compressed air that meets the requirements of pneumatic components such as the locomotive's braking system, pantograph lifting device, and door control mechanism. This provides stable power for critical operations like service braking, parking braking, and auxiliary equipment driving. In short, the operational reliability of the air compressor directly determines the driving safety and operational efficiency of the electric locomotive.

[0023] In the operation of electric locomotives, the air compressor needs to work continuously or intermittently to maintain stable pressure in the air circuit system. Its core internal components are male and female rotors. Driven by a motor, these rotors mesh and rotate at high speed, compressing the air entering the locomotive housing. During this process, friction between the rotor and the air, violent collisions of air molecules, and friction between the rotor and the lubricating oil all generate a significant amount of heat. Simultaneously, the mechanical compartment of an electric locomotive is relatively enclosed, especially in high-temperature environments during summer or in long tunnel operations, where the ambient temperature can rise to around 70°C, further exacerbating the heat dissipation pressure on the air compressor. If this heat cannot be effectively dissipated in time, it will cause a sharp increase in the compressor's exhaust temperature, triggering the temperature protection switch and resulting in a "failure to operate" malfunction, directly affecting the normal operation of the locomotive.

[0024] Currently, air compressors typically use two methods—lubricating oil and cooling air—to force convection. A motor drives a cooling fan to force air towards the cooler, causing the heat from the compressed air and lubricating oil to flow outside the unit, thus achieving the purpose of cooling the compressed air and lubricating oil.

[0025] For example, such as Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of the main circuit structure of a lubricating oil system, illustrating an exemplary embodiment of this application. Figure 2 This is a schematic diagram of the auxiliary circuit structure of a lubricating oil system shown in an exemplary embodiment of this application. The lubricating oil system includes an oil-gas chamber 10, a temperature control valve 20, an oil filter 30, an oil cooler 40, an oil separator 50, an oil return pipe 60, and a machine body 70.

[0026] like Figure 1As shown, in the main circuit of the lubricating oil system, the lubricating oil is forced out from the bottom of the oil-gas chamber 10 and then passes through the temperature control valve 20. The temperature control valve 20 is configured to close the passage to the oil cooler 40 when the lubricating oil temperature is less than 77°C, so that the lubricating oil returns directly to the machine body 70 after exiting the oil filter 30. When the lubricating oil temperature is greater than or equal to 77°C, the lubricating oil needs to be cooled to maintain its lubrication and cooling performance. At this time, the temperature control valve 20 will open the passage to the oil cooler 40 and close or reduce the short-circuit passage directly returning to the machine body 70. The lubricating oil will then flow through the oil cooler 40 to cool down before entering the machine body 70. The filtered and cooled lubricating oil is sprayed into the machine body 70 to lubricate the high-speed rotating male and female rotors, seal the gap between the rotors, and absorb the heat generated during compression.

[0027] like Figure 2 As shown, in the auxiliary circuit of the lubricating oil system, the lubricating oil is forced out from the bottom of the oil-gas chamber 10 and mixed with compressed air to form a high-pressure oil-gas mixture. Then it enters the oil-fine separator 50, where the oil droplets in the oil-gas mixture are condensed into larger oil droplets and separated. The separated clean compressed air is sent to the air consumption point from the top outlet. The lubricating oil intercepted by the filter element of the oil-fine separator 50 returns to the machine body 70 through the oil return pipe 60 and rejoins the main circuit circulation.

[0028] Traditionally, the cooling system of an air compressor typically consists of components such as a centrifugal fan, an oil cooler, and an aftercooler. (Combined with...) Figure 3 As shown, Figure 3 This is a schematic diagram of the structure of a centrifugal fan in a cooling system, as illustrated in an exemplary embodiment of this application. Figure 3 The centrifugal fan includes a motor 31, an impeller 32, an air guide 33, a connecting flange 34, a main unit 35, a coupling 36, a volute 37, and an air guide shroud 38. The motor 31 drives the impeller 32 to rotate. At this time, the air between the blades is thrown at high speed towards the edge by centrifugal force, forming a low-pressure zone in the center of the impeller. This continuously draws in external air through the air guide 33. The centrifugal fan is mounted on the main unit 35 via the connecting flange 34. The coupling 36 connects the motor shaft and the main unit shaft, transmitting the motor's rotational power to the main unit 35. The volute 37 is also the fan housing. The spiral structure of the volute effectively gathers the high-speed airflow generated by the impeller 32, achieving deceleration and pressurization of the airflow, and guiding the gas towards the air guide shroud 38 for directional discharge. This ensures the gas is evenly blown over the cooling fins of the oil cooler and aftercooler, simultaneously cooling the compressed air and lubricating oil.

[0029] However, in traditional technologies, due to external environmental factors, such as excessively high ambient temperatures, the air delivered by the cooling fan is already at a high temperature, reducing the temperature difference between the air and the cooler. This significantly decreases heat exchange efficiency, making it difficult to quickly dissipate the large amount of heat generated during equipment operation, resulting in poor heat dissipation and posing a risk of equipment failure due to overheating. Therefore, there is an urgent need for a technical solution that can improve the heat dissipation efficiency of air compressors.

[0030] Based on this, this application proposes a heat dissipation control method and device for air compressors, electronic equipment, and storage medium to solve the problem of poor heat dissipation efficiency of air compressors.

[0031] To facilitate understanding of the heat dissipation control method for the air compressor provided in the embodiments of this application, the following is combined with... Figure 1 The illustrated implementation environment describes a scenario for heat dissipation control of an air compressor. The heat dissipation control method for an air compressor provided in this application embodiment can be applied to scenarios such as... Figure 4 In the illustrated implementation environment, the environment includes a terminal 410 and an auxiliary heat dissipation device 420. The terminal 410 and the auxiliary heat dissipation device 420 can communicate via a network, which can be a wired or wireless network. Therefore, the terminal 410 and the auxiliary heat dissipation device 420 can be directly or indirectly connected via wired or wireless communication. For example, the terminal 410 can be indirectly connected to the auxiliary heat dissipation device 420 via a wireless access point, or the terminal 410 can be directly connected to the auxiliary heat dissipation device 420 via the Internet; this application does not impose any limitations on this.

[0032] Among them, the terminal 410 may be, but is not limited to, mobile phones, tablets, wearable devices (such as watches, bracelets, smart helmets, etc.), in-vehicle devices, smart home devices, augmented reality (AR) / virtual reality (VR) devices, laptops, ultra-mobile personal computers (UMPCs), netbooks, personal digital assistants (PDAs), etc.

[0033] The auxiliary heat dissipation device 420 is used to dissipate heat from the air compressor in order to improve the heat dissipation efficiency of the air compressor.

[0034] In some embodiments, combined with Figure 5 As shown, Figure 5 This is a schematic diagram of the structure of an auxiliary heat dissipation device shown in an exemplary embodiment of this application. Figure 5In this system, the auxiliary heat dissipation device includes a temperature sensor 510, a cylinder 530, a first solenoid valve 540, and an air amplifier 560. The auxiliary heat dissipation device is mounted on the surface of the cooler via the mounting surface of the air amplifier 560. The temperature sensor 510 is located at the air compressor's intake throat to collect the compressor's suction temperature. The first solenoid valve 540 is configured to controllably supply or stop supplying compressed air stored in the cylinder 530 to the air amplifier 560. The air amplifier 560 converts the compressed air into a cooling airflow to dissipate heat from the cooler. In this way, the air amplifier 560 utilizes the Coanda effect to mix the compressed air supplied in the cylinder with the cooling air, forming a high-speed, high-capacity airflow that is discharged. This quickly removes excess heat generated during the operation of the air compressor, significantly reducing the equipment's exhaust temperature and improving the air compressor's heat dissipation efficiency, enabling the air compressor to operate normally even in high-temperature environments.

[0035] In some other embodiments, the auxiliary heat dissipation device further includes a second solenoid valve 520, one end of which is connected to the air cylinder 530 and the other end of which is connected to the air intake pipe of the air compressor. The second solenoid valve 520 is used to controllably replenish or stop replenishing compressed air to the air cylinder 530.

[0036] In other embodiments, the auxiliary cooling device further includes a pressure reducing valve 550, which is disposed between the first solenoid valve 540 and the air amplifier 560. The pressure reducing valve 550 is used to reduce the pressure of the compressed air delivered by the air cylinder 530 to a preset pressure before delivering it to the air amplifier 560. For example, the preset pressure may be in the range of 500 to 700 kPa.

[0037] In some embodiments, the air amplifier employs an annular nozzle, which is the primary location for pressure loss and can form a stable jet. For example, the width of the annular nozzle ranges from 0.05 to 0.1 mm. In this embodiment, the width of the annular nozzle in the air amplifier can be 0.06 mm. Furthermore, the sidewall inclination angle of the air amplifier is 10°, and the flow cross-sectional area of ​​the air amplifier is 80.07 mm². 2 The air amplifier has a mass flow rate of 0.095 kg / s and a cylinder volume of 200 L. Furthermore, to ensure the jet adhesion effect, a 16 mm diameter stainless steel pipe is selected as the connecting pipeline in this embodiment. Also, since the cooling effect of the air amplifier is not linearly positively correlated with the supply air pressure, the cooling effect becomes more pronounced as the supply air pressure increases, even at lower supply pressures. The optimal supply air pressure range for the air amplifier is 500–700 kPa. In this embodiment, the supply air pressure is 500 kPa, meaning the preset pressure of the pressure reducing valve 550 is 500 kPa.

[0038] The heat dissipation control method for an air compressor provided in the embodiments of this application will be described in detail below.

[0039] Please continue reading. Figure 6 , Figure 6 This is a flowchart illustrating a heat dissipation control method for an air compressor, as shown in an exemplary embodiment of this application. This method can be applied to... Figure 4 The implementation environment shown can be, for example, by Figure 4 The method can be executed by the terminal 410 or the auxiliary heat dissipation device 420 in the illustrated implementation environment, or by the terminal 410 and the auxiliary heat dissipation device 420 together; this is not a limitation. Of course, this method can also be applied to other implementation environments and executed by the terminal or the high-temperature reactor in other implementation environments, or by the terminal or the high-temperature reactor in other implementation environments together; this embodiment does not limit this as well.

[0040] like Figure 6 As shown, in an exemplary embodiment, an auxiliary heat dissipation device is provided on the cooler connected to the air compressor. The auxiliary heat dissipation device includes a temperature sensor, a blower cylinder, a first solenoid valve, and an air amplifier. The auxiliary heat dissipation device is mounted on the surface of the cooler through the mounting surface of the air amplifier. The first solenoid valve is configured to controllably supply or stop supplying compressed air stored in the blower cylinder to the air amplifier. The air amplifier is used to convert the compressed air into a cooling airflow to dissipate heat from the cooler. The heat dissipation control method of the air compressor includes at least steps S610 to S620, which are described in detail below: Step S610: Obtain the control switch status of the air compressor and the intake temperature of the air compressor through the temperature sensor.

[0041] It is important to understand that the heat dissipation efficiency of an air compressor is related to whether it is running and its operating load. If the air compressor is in a stopped state, i.e., the control switch is in the off position, there is no additional heat generated, and therefore no need to activate auxiliary cooling. Similarly, if the air compressor is running, i.e., the control switch is in the closed position, heat dissipation can be achieved solely through the cooler, and no auxiliary cooling is needed. Furthermore, the air compressor's intake temperature directly reflects the degree of heat accumulation on the intake side. When the intake temperature is too high, relying solely on the cooler for heat dissipation can easily lead to poor air compressor heat dissipation efficiency, resulting in increased compressor exhaust temperature, accelerated lubricant aging, seal damage, and reduced equipment lifespan. Therefore, in this embodiment, by collecting the air compressor's control switch status, the auxiliary cooling device can be precisely controlled based on the air compressor's operating status, avoiding ineffective heat dissipation during non-operational states. Furthermore, by collecting the air compressor's intake temperature, the temperature change trend during operation can be captured, thereby accurately matching heat dissipation requirements and avoiding overheating or underheating. This provides multi-dimensional decision-making basis for subsequent precise control of the auxiliary cooling device, avoiding control misjudgments caused by a single parameter.

[0042] In some embodiments, the control switch state of the air compressor includes a closed state and an open state. For example, the control switch of the air compressor may be a toggle switch, which is a dedicated switching device for controlling the operating state of the air compressor. The control switch state may be the position of the toggle switch, which may include the closed position, the high-pressure pump position, and the stop position.

[0043] The "closed" position refers to the air compressor's control switch being in the closed state. However, the air compressor automatically starts and stops based on the pressure setting. For example, when the system pressure is lower than the set lower limit (e.g., 750 kPa), the toggle switch automatically closes and the compressor starts working; when the pressure reaches the set upper limit (e.g., 900 ± 20 kPa), the toggle switch automatically opens and the compressor stops running.

[0044] "Forced pump position" also refers to the air compressor's control switch being closed, but at this time the air compressor is not limited by pressure and is forced to work continuously.

[0045] The stop position refers to the air compressor's control switch being in the off state.

[0046] In some embodiments, a temperature sensor may be located at the air intake throat of the air compressor to collect the air intake temperature of the air compressor.

[0047] Step S620: Control the first solenoid valve according to the control switch status and the intake temperature.

[0048] In this embodiment, the first solenoid valve is controlled by controlling both the switch state and the intake temperature. This enables on-demand control of the auxiliary cooling device to dissipate heat, avoiding the problem of poor heat dissipation efficiency of the air compressor due to miscontrol of a single parameter. At the same time, controlling both the switch state and the intake temperature allows for precise control of the start-up timing of the auxiliary cooling device, ensuring that the intake temperature remains stable within a safe range. This prevents performance degradation and failure risks of the air compressor due to heat accumulation, and extends the overall service life of the equipment.

[0049] In some embodiments, combined with Figure 7 As shown, Figure 7 yes Figure 6 The flowchart of step S620 in the illustrated embodiment is a method for controlling the first solenoid valve according to the control switch state and the intake temperature in an exemplary embodiment; it includes at least steps S710 to S720, which are described in detail below: In step S710, if the control switch is in the closed state and the intake temperature is higher than the preset temperature threshold, the first solenoid valve is turned on to deliver the compressed air stored in the air cylinder to the air amplifier.

[0050] In this embodiment, when the air compressor is running (i.e., the control switch is closed) and the intake temperature exceeds the limit, it is considered that relying solely on the original cooling system (i.e., the cooler) of the air compressor is insufficient to meet the heat dissipation requirements, resulting in poor heat dissipation efficiency. Activating the auxiliary cooling device at this time allows for precise control of the auxiliary cooling device, avoiding unnecessary energy consumption. Simultaneously, after the compressed air stored in the air cylinder is delivered to the air amplifier, the air amplifier can rapidly generate cooling airflow using the Coanda effect, thereby improving heat dissipation efficiency, suppressing continuous temperature increases, and preventing problems such as excessive exhaust temperature, lubricating oil aging, and seal damage caused by heat accumulation in the air compressor.

[0051] In some embodiments, the preset temperature threshold can be 68°C.

[0052] In step S720, if the control switch is in the off state, or the intake temperature is less than the preset temperature threshold, the first solenoid valve is controlled to open to stop the delivery of compressed air stored in the air cylinder to the air amplifier.

[0053] In this embodiment, when the air compressor is in a stopped state (i.e., the control switch is in an open state), or when the intake temperature is not exceeded, the first solenoid valve is promptly disconnected to stop the delivery of compressed air. This avoids the ineffective consumption of compressed air in the air cylinder, reduces the energy consumption for air replenishment in the air compressor, and lowers the overall operating cost. Furthermore, by disconnecting the first solenoid valve at a timed interval, secondary problems such as lubricating oil emulsification caused by excessive heat dissipation leading to exhaust temperatures below the pressure dew point temperature can be prevented.

[0054] In other embodiments, Figure 8 yes Figure 6 Step S620 in the illustrated embodiment is a flowchart of a method for controlling the first solenoid valve based on the control switch state and the intake temperature in another exemplary embodiment; it includes at least steps S810 to S840, which are described in detail below: Step S810: Obtain the ambient temperature of the air compressor.

[0055] Step S820: Adjust the preset temperature threshold according to the ambient temperature to obtain a dynamic temperature threshold.

[0056] It is important to understand that using only a fixed temperature threshold for judgment under different ambient temperatures will affect the heat dissipation efficiency of the air compressor. For example, in high-temperature environments (such as ambient temperatures exceeding 65°C), the heat dissipation demand of the air compressor increases, and the activation temperature threshold of the auxiliary heat dissipation device (i.e., the preset temperature threshold) can be lowered for early intervention. Conversely, in low-temperature environments (such as ambient temperatures below 10°C), the heat dissipation demand of the air compressor is lower, and the threshold can be raised to avoid unnecessary activation of the auxiliary heat dissipation device, thereby saving compressed air stored in the air cylinder and reducing the overall operating cost of the machine. Therefore, in this embodiment, the preset temperature threshold can be adjusted according to the environment to obtain a more suitable dynamic temperature threshold.

[0057] In step S830, if the control switch is in the closed state and the intake temperature is higher than the dynamic temperature threshold, the first solenoid valve is turned on to deliver the compressed air stored in the air cylinder to the air amplifier.

[0058] In step S840, if the control switch is not in a closed state, or the intake temperature is less than the dynamic preset temperature threshold, the first solenoid valve is opened to stop the delivery of compressed air stored in the air cylinder to the air amplifier.

[0059] In this embodiment, by dynamically adjusting the fixed preset temperature threshold based on the ambient temperature, the control of the auxiliary heat dissipation device can be made more accurate, thereby further improving the heat dissipation efficiency of the air compressor.

[0060] In some embodiments, combined with Figure 9 As shown, Figure 9 This application illustrates another exemplary embodiment of a heat dissipation control method for an air compressor. Figure 6 Based on the auxiliary heat dissipation device of the illustrated embodiment, the auxiliary heat dissipation device further includes a second solenoid valve. One end of the second solenoid valve is connected to the air cylinder, and the other end of the second solenoid valve is connected to the air intake pipe of the air compressor. The heat dissipation control method of the air compressor further includes at least steps S910 to S930, which are described in detail below: Step S910: Perform real-time pressure detection on the compressed air stored in the air cylinder to obtain the pressure detection result.

[0061] It is understandable that the air cylinder, as a compressed air storage component in the auxiliary cooling system, may experience a natural pressure drop even when the auxiliary cooling system is not activated, due to minor leaks in the seals or changes in ambient temperature (thermal expansion and contraction). When the auxiliary cooling system is activated, the release of compressed air directly causes a rapid pressure drop. Without real-time monitoring, the pressure status of the air cylinder cannot be determined, potentially leading to problems where the auxiliary cooling system fails to achieve the expected cooling effect after activation. Therefore, it is necessary to perform real-time pressure monitoring of the compressed air stored in the air cylinder to facilitate subsequent replenishment based on the pressure monitoring results.

[0062] In some embodiments, a pressure sensor can be installed inside the air cylinder to collect the current pressure of the air cylinder and use the current pressure of the air cylinder as the pressure detection result.

[0063] For example, the current pressure of the air cylinder can be continuously collected a preset number of times. The collected data is then preprocessed to remove outliers, and the remaining data is averaged to obtain the pressure detection result. For instance, during the preprocessing to remove outliers, if the difference between two consecutive data points exceeds a preset range, the current data is removed as an outlier. This improves the accuracy of the pressure detection results.

[0064] In step S920, if the pressure detection result is lower than the preset pressure threshold, the second solenoid valve is controlled to open to replenish the air cylinder with compressed air.

[0065] In this embodiment, when the pressure is lower than a preset threshold, the second solenoid valve is immediately activated, and compressed air is replenished in real time through the air compressor intake throat to ensure that the air amplifier always receives sufficient air pressure. This prevents the auxiliary heat dissipation device from failing due to a continuous drop in cylinder pressure. Furthermore, by using the compressed air from the air compressor itself to replenish the cylinder, no additional air replenishment equipment is required, simplifying the system structure and reducing heat dissipation costs. At the same time, the air replenishment logic is strongly linked to the compressor's operating status (stable compressed air in the intake throat) to ensure a reliable air replenishment source.

[0066] In step S930, if the pressure detection result is greater than or equal to the preset pressure threshold, the second solenoid valve is controlled to disconnect to stop the supply of compressed air to the air cylinder.

[0067] In this embodiment, the second solenoid valve is immediately disconnected after the pressure reaches the preset threshold to stop the air supply. This can prevent the air compressor from generating additional load due to continuous air supply to the air cylinder, reduce the overall energy consumption, and at the same time prevent the air cylinder pressure from being too high, thus preventing safety hazards such as damage to the air cylinder seals, pipeline leakage, or even rupture due to pressure overload.

[0068] It should be noted that the steps in this embodiment are consistent with the corresponding steps in the foregoing embodiments. Therefore, for a detailed description of these steps, please refer to the description in the foregoing embodiments. This embodiment will not repeat them here.

[0069] In some embodiments, combined with Figure 10 As shown, Figure 10 This is another exemplary embodiment of the present application illustrating a heat dissipation control method for an air compressor. Figure 6 After step S620 in the illustrated embodiment, the air compressor heat dissipation control method further includes at least steps S1010 to S1020, which are described in detail below: Step S1010: Obtain the rate of change of inhalation temperature.

[0070] In this embodiment, since the intake temperature directly reflects the degree of heat accumulation on the intake side, its rate of change is strongly correlated with the heat exchange efficiency of the cooler, the ambient temperature, and the compressor load. If the cooler's heat dissipation is insufficient, the intake temperature will show a slow cooling or heating trend before the exhaust temperature. Therefore, the rate of change of the intake temperature can be obtained to accurately identify the heat dissipation effect of the air compressor.

[0071] For example, if the ambient temperature is 70°C, the air compressor is operating at high load, and the intake air temperature rises to 50°C, with a preset temperature threshold of 49°C, then the first solenoid valve is activated (e.g., initially at 50% opening), and the auxiliary cooling device is started to dissipate heat. The intake air temperature is collected every preset time interval (e.g., 10 seconds) by a temperature sensor in the auxiliary cooling device, and a preset set of data (e.g., 3 sets) is continuously collected. First set of data: t1=0s, T1=50℃; Second set of data: t2=10s, T2=49.2℃; The third set of data: t3 = 20s, T3 = 48.7℃; The rate of change of the intake temperature is obtained by calculating ΔT / Δt = (T2 - T0) / (t2 - t0) = (48.7 - 50) / 20 = -0.065℃ / s = -3.9℃ / min (the negative sign indicates cooling). Here, ΔT / Δt represents the rate of change of the intake temperature. In this way, by continuously collecting temperature data and calculating the rate of change, the heat dissipation effect can be understood in real time, providing a quantitative basis for whether to adjust the opening of the first solenoid valve.

[0072] In step S1020, if the rate of change of the intake temperature is lower than the preset expected cooling rate within a preset time period, the first solenoid valve is controlled to increase its opening to increase the flow of compressed air delivered to the air amplifier and a heat dissipation alarm is generated.

[0073] In this embodiment, by increasing the opening of the first solenoid valve, the compressed air flow rate is increased, thereby improving the ejector ratio and cooling airflow intensity of the air amplifier. This compensates for the original insufficient heat dissipation effect, prevents the intake temperature from continuously rising, and thus improves heat dissipation efficiency. Furthermore, by generating a heat dissipation alarm, maintenance personnel can be alerted to investigate potential problems (such as scale buildup in the cooler, blockage of the air amplifier nozzle, or insufficient air cylinder pressure), preventing minor faults from escalating into equipment downtime and improving the operational reliability of the air compressor.

[0074] For example, if the preset desired cooling rate is -5℃ / min, the preset time period is 20s, the initial opening of the first solenoid valve is 50%, and the air supply flow rate is 0.095kg / s, and the calculated rate of change of the intake temperature is -3.9℃ / min, which is lower than the desired cooling rate, then the opening of the first solenoid valve is increased from 50% to 80%, the compressed air flow rate is increased from 0.095kg / s to 0.15kg / s, and the total cooling air mass flow rate of the air amplifier is increased from 1.995kg / s to 3.15kg / s (with the ejector ratio maintained at 1:20). Simultaneously, the control system displays an alarm message "Poor heat dissipation" on the terminal display interface and sounds a buzzer. The alarm information is synchronously uploaded to the database, and parameters such as the alarm time, current intake temperature, and valve opening are recorded for maintenance personnel to view.

[0075] In some embodiments, taking a preset type (e.g., TSA-2.4A type) of air compressor as an example, the mass flow rate of cooling air drawn into its cooling system is 0.76 kg / s. Numerical simulation analysis shows that under the action of the centrifugal fan, the cooling air temperature will decrease by about 15°C. Under an ambient temperature of 30°C, based on the fitting formula of the experimental data of the air compressor's exhaust temperature, an empirical formula can be derived for an ambient temperature of 70°C: Exhaust temperature = -0.9t 2 +14.01t+84.28; where t represents the working time of the air compressor, so it can be estimated that the exhaust temperature after 3 minutes of operation is 118.21℃. At this time, the temperature protection switch has reached the action value of 120±4℃, which will control the air compressor to shut down.

[0076] The air amplifier in the auxiliary cooling device of this application embodiment has an air supply pressure of 500 kPa and an ejection ratio of over 1:20, meaning that each unit of air supplied can eject more than 20 times the amount of ambient air. Therefore, when the air supply flow rate is 0.095 kg / s, the total mass flow rate of the air amplifier during operation is greater than 0.095 × 21 = 1.995 kg / s, and the ratio of this mass flow rate to the mass flow rate drawn into the cooling system is greater than 2.63. Based on the derivation of the ideal gas law, mass flow rate and temperature are negatively correlated. The auxiliary cooling device in this application embodiment can reduce the exhaust temperature of the air compressor by 6-8°C, or even higher, making the exhaust temperature lower than the operating value of the temperature protection switch (120 ± 4°C). This ensures normal operation in high-temperature environments (e.g., ambient temperature of 70°C), enabling safe operation of the locomotive and reducing the loss of lubricating oil with compressed air, thus preventing oil contamination of subsequent braking components. Meanwhile, the higher the ambient temperature at which the air compressor operates, the greater the motor power required for its male and female rotors to perform work. The auxiliary heat dissipation device in this embodiment can reduce the exhaust temperature of the compressed air, thereby promoting the lubricating oil temperature to quickly reach a stable equilibrium state, which can improve its working efficiency and thus reduce motor energy consumption.

[0077] In other embodiments, after controlling the first solenoid valve according to the control switch state and the intake temperature, if the control switch state changes from closed to open, the current intake temperature of the air compressor is obtained; if the current intake temperature is higher than a preset safety threshold, the first solenoid valve is subjected to delayed conduction control until the duration of the delayed conduction control reaches the preset delay duration, or the current intake temperature is lower than the preset safety threshold.

[0078] It is understandable that after the air compressor stops, a lot of heat may still accumulate inside (especially in the compression chamber and cooler). If all heat dissipation is stopped immediately, heat accumulation may occur, accelerating the aging of lubricating oil or causing thermal damage to components. In this embodiment, by providing a controllable delayed heat dissipation after shutdown, it is possible to ensure that the temperature of critical components is safely reduced to a low level before completely stopping heat dissipation, which helps to extend the equipment life and ensure the safety of the next startup.
