Description

Technical Field

[0001] The present disclosure relates to the technical field of power supply safety control, and particularly to a power supply temperature control system.

Background Art

[0002] In a low-temperature environment, the DC bus (DC-Link) of a high-frequency power supply cabinet faces the risk of a fault trip. This fault trip not only affects the normal operation of the equipment but may also damage the entire system, leading to unnecessary downtime and repair costs. Therefore, it has become particularly important to find an effective method to prevent such fault trips in a low-temperature environment.

[0003] Currently, power supply equipment in related technologies generally has heat dissipation fans for heat dissipation. However, the start and stop of these fans depend on manual control and often cannot be smartly adjusted based on the actual changes in the internal temperature of the power supply.

[0016] Please understand that the above general explanation and the detailed explanation below are illustrative and interpretive and do not limit this disclosure. [Brief explanation of the drawing]

[0017] The drawings herein are incorporated into and constitute part of the specification, illustrate embodiments conforming to the disclosure, and are used together with the specification to interpret the principles of the disclosure, and do not constitute an inappropriate limitation to the disclosure.

[0018] [Figure 1] This is a schematic diagram of a power supply temperature control system according to an example of application of this disclosure. [Figure 2] This is a schematic flowchart of a power supply temperature control method according to an application example of this disclosure. [Figure 3] This is a schematic diagram of a power supply temperature control device according to an example of application of this disclosure. [Figure 4] This is a schematic diagram of the configuration of an electronic device based on an example of application of this disclosure. [Modes for carrying out the invention]

[0019] The embodiments of this disclosure are described in detail below. Examples of embodiments are shown in the drawings, and the same or similar reference numerals from beginning to end represent the same or similar elements, or elements having the same or similar functions. The embodiments described below with reference to the drawings are illustrative and are intended to be interpretable as part of this disclosure, but not to be understood as limitations thereto.

[0020] In low-temperature environments, the DC bus (DC-Link) of high-frequency power supply cabinets faces the risk of failure tripping. This failure tripping not only affects the normal operation of the equipment but can also damage the entire system, leading to unnecessary downtime and repair costs. Therefore, finding effective methods to prevent failure tripping in such low-temperature environments is particularly important.

[0021] Currently, power supply devices in related technologies generally have a cooling fan installed for heat dissipation. However, the startup and stop of these fans depend on manual control and often cannot be smartly adjusted based on the actual changes in the internal temperature of the power supply. Therefore, in a low-temperature environment, these fans may not be able to effectively prevent malfunction trips due to overly low temperatures.

[0022] Regarding the problems of the above related technologies, the power supply temperature control system of the present disclosure realizes real-time monitoring and smart control of the internal temperature of the power supply by introducing a temperature sensing element and a startup and stop control unit. When the internal temperature of the power supply drops to a certain extent, the startup and stop control unit automatically turns off the cooling fan to prevent low-temperature malfunction trips caused by excessive heat dissipation. When the internal temperature of the power supply rises, the startup and stop control unit timely starts the cooling fan to ensure normal heat dissipation of the power supply. This smart control mechanism not only improves the stability and reliability of the device but also reduces the maintenance cost.

[0023] Hereinafter, in combination with the drawings, the implementation of the power supply temperature control system, method, device, electronic device, and medium according to the present disclosure will be described in detail.

[0024] FIG. 1 is a schematic diagram of a power supply temperature control system according to an embodiment of the present disclosure. As shown in FIG. 1, this system includes a power supply, a cooling fan, and a startup and stop control unit, a temperature sensing element for monitoring the internal temperature of the power supply is provided inside the power supply, the cooling fan is provided on or inside the case of the power supply and is used to dissipate heat from the power supply, the startup and stop control unit is connected to the cooling fan and the temperature sensing element and is used to control the startup and stop of the cooling fan based on the internal temperature of the power supply.

[0025] The power supply is the energy source for the entire system, supplying energy to the cooling fan and the start / stop control unit. The power supply contains one or more temperature-sensing elements (e.g., thermistors, thermocouples, or integrated temperature sensors). These temperature-sensing elements can monitor the internal temperature of the power supply in real time and convert the temperature information into electrical signals.

[0026] Cooling fans are crucial components for lowering power supply temperatures. They are typically mounted on or inside the power supply case and rotate to generate airflow, thereby removing heat generated within the power supply. The design, size, and rotation speed of cooling fans can be determined based on the power supply's power, operating environment, and heat dissipation requirements.

[0027] The start / stop control unit is the smart core of the power supply temperature control system. It receives temperature signals from the temperature sensing element and controls the start and stop of the cooling fan based on a preset temperature threshold.

[0028] When the internal temperature of the power supply exceeds a set first preset temperature threshold, the start-stop control unit activates the cooling fan to improve heat dissipation and lower the power supply temperature. When the internal temperature of the power supply is below the first preset temperature threshold, the start-stop control unit stops the fan to save energy and reduce noise.

[0029] The start / stop control unit can also achieve more precise temperature control by adjusting the rotation speed of the cooling fan based on changes in the internal temperature of the power supply.

[0030] Specifically, in this disclosure, the power supply generates heat during operation, and a temperature-sensing element monitors the power supply temperature changes caused by this heat in real time. When the power supply temperature reaches or exceeds a set first preset temperature threshold, the start-stop control unit triggers the activation of a cooling fan to remove heat and lower the temperature through airflow. When the power supply temperature is below the set first preset temperature threshold, the start-stop control unit stops the cooling fan to avoid unnecessary energy consumption and noise. This ensures that the power supply operates within a safe temperature range, extends its service life, and protects connected electronic equipment from overheating damage.

[0031] In some embodiments, the temperature-sensing element is a thermistor or thermocouple, used to convert a temperature signal corresponding to the internal temperature of the power supply into an electrical signal and transmit it to a start / stop control unit.

[0032] A temperature-sensing element converts the internal temperature of a power supply into an electrical signal, which is then transmitted to a comparator in a start / stop control unit for comparison. For example, the resistance of a thermistor changes in response to temperature changes, and this change can be converted into an electrical signal. A thermocouple measures temperature using the electromotive force generated by a temperature gradient between two different metals, and converts this electromotive force into an electrical signal.

[0033] In some embodiments, the start / stop control unit includes a comparator for controlling the start and stop of the cooling fan based on the comparison result, by comparing the temperature detected by a temperature sensing element with a first preset temperature threshold.

[0034] The comparator plays the role of comparing the internal temperature of the power supply detected by the temperature-sensing element with a preset first temperature threshold.

[0035] A temperature-sensing element (e.g., a thermistor or thermocouple) detects the internal temperature of the power supply and converts it into an electrical signal, which is then transmitted to a comparator. The comparator compares this electrical signal (representing the current internal temperature of the power supply) with a preset first temperature threshold. If the current internal temperature of the power supply is higher than the first temperature threshold, the comparator outputs a signal instructing the start / stop control unit to activate the cooling fan and lower the internal temperature of the power supply. If the current internal temperature of the power supply is below the first temperature threshold, the comparator either does not output a signal to activate the fan, or outputs a signal instructing the fan to remain stopped.

[0036] In some embodiments, the start / stop control unit further includes a delay module for obtaining the internal temperature of the power supply after the cooling fan has stopped, by a preset delay time.

[0037] The delay module provides a preset delay time, during which the internal temperature of the power supply is re-detected.

[0038] After the cooling fan stops operating based on the comparator's instructions, the delay module begins measuring time. Even if the internal temperature of the power supply rises before the delay time ends, the fan will not start immediately. After the delay time ends, the temperature sensor re-detects the internal temperature of the power supply and sends this new temperature signal to the comparator for a new comparison. The purpose is to prevent the cooling fan from frequently starting and stopping due to small temperature fluctuations, thereby extending the fan's lifespan and reducing energy loss.

[0039] In some embodiments, the system further includes a smart adjustment module connected to a start / stop control unit and a cooling fan, which adjusts the rotation speed of the cooling fan when it detects that the internal temperature of the power supply is above a second preset temperature threshold.

[0040] The smart adjustment module is connected to the start / stop control unit and the cooling fan, and can dynamically adjust the rotation speed of the cooling fan when it detects that the internal temperature of the power supply is above a second preset temperature threshold.

[0041] When the temperature sensor detects that the internal temperature of the power supply has risen and reached or exceeded a second preset temperature threshold (this threshold may be lower than the first preset temperature threshold to respond to the temperature rise early, or higher than the first preset temperature threshold to rapidly lower the temperature when the internal temperature of the power supply is too high), the smart adjustment module receives a corresponding signal. Based on a preset algorithm or policy, it then determines the current rotation speed of the cooling fan and sends a control signal to the cooling fan via the start / stop control unit to adjust its rotation speed. By intelligently adjusting the fan speed, the smart adjustment module ensures that the power supply is effectively cooled, reduces energy loss and noise, and improves the overall efficiency of the system.

[0042] In some embodiments, the system further includes an ambient noise sensor connected to a start / stop control unit and a cooling fan, which monitors ambient noise, feeds back noise data to the start / stop control unit, and causes the start / stop control unit to adjust the rotation speed of the cooling fan based on the noise data.

[0043] The ambient noise sensor is used to monitor ambient noise and feed the noise data back to the start / stop control unit. The ambient noise sensor can detect the noise level at its location in real time and convert this data into electrical signals to transmit to the start / stop control unit. Based on the received noise data, the start / stop control unit comprehensively determines whether it is necessary to adjust the fan speed to reduce noise, taking into account information such as the current internal temperature of the power supply and the fan speed. By monitoring ambient noise and adjusting the fan speed accordingly, the heat dissipation requirements are met while reducing noise interference from the surrounding environment.

[0044] In some embodiments, the system further includes a fan health monitoring module connected to a cooling fan and a start / stop control unit, which monitors the operating parameters of the cooling fan and issues fan alert signals based on the operating parameters.

[0045] The fan health monitoring module is connected to the cooling fan and the start / stop control unit, and is used to monitor the operating parameters of the cooling fan and issue fan alert signals based on these parameters. Specifically, the fan health monitoring module can acquire important operating parameters such as the cooling fan's rotation speed, current, and voltage in real time, and can analyze and monitor these parameters in real time. If abnormal or out-of-range parameters are detected, the fan health monitoring module immediately issues an alert signal to the start / stop control unit, drawing the attention of system administrators to inspect or replace the fan. This enables real-time monitoring of the fan's operating status and issuance of alert signals, allowing for timely detection and handling of fan failures, preventing power supply overheating and damage due to fan malfunctions, and improving system reliability and stability.

[0046] In some embodiments, the system further includes a temperature warning module connected to a start / stop control unit and a temperature sensing element, which monitors the temperature status of the power supply and issues an alarm if the temperature is abnormal.

[0047] The temperature warning module is connected to the start / stop control unit and the thermosensing element, and monitors the temperature status of the power supply and the operation status of the cooling fan, issuing an alarm if the temperature is abnormal. Specifically, the temperature warning module continuously receives real-time internal temperature data of the power supply from the thermosensing element and compares it with a preset temperature threshold. If the temperature exceeds the safe range temperature, the temperature warning module immediately triggers the alarm mechanism and notifies system administrators and relevant personnel through methods such as acoustic-optical alarms, text messages, and email. In this way, the temperature warning module ensures that system administrators are the first to know about power supply temperature abnormalities or fan failures by issuing alarms in a timely manner, thereby enabling prompt action and preventing serious consequences such as equipment damage or fire caused by excessively high temperatures.

[0048] In some embodiments, the start-stop control unit further includes a memory module for storing the internal temperature of the power supply under different operating environments.

[0049] The memory module in the start-stop control unit is used to store internal power supply temperature data under different operating environments, thereby obtaining a temperature curve corresponding to the power supply. This allows operators to obtain information on the power supply's temperature changes, optimize the heat dissipation policy, and improve system stability and reliability. The memory module may employ non-volatile memory to ensure that data is not lost when the power is turned off or the system fails.

[0050] In some embodiments, the system further includes a fault detection module for monitoring the operating status of the start / stop control unit, the cooling fan, and the temperature sensing element, and for activating a self-protection mechanism and issuing a fault alert if it detects a failure in any one of the start / stop control unit, the cooling fan, or the temperature sensing element.

[0051] The fault detection module monitors the operating status of the start / stop control unit, cooling fan, and temperature sensing element, and is used to activate a self-protection mechanism and issue a warning about the fault when a fault is detected.

[0052] Specifically, the fault detection module determines whether a component is operating normally by detecting the electrical parameters (e.g., voltage, current), operating status (e.g., fan speed, temperature sensor output signal), and communication status of each component in real time. If an abnormality is detected, the module immediately activates a self-protection mechanism, such as turning off the faulty component and switching to a backup power supply, to prevent the fault from spreading or leading to more serious consequences. The fault detection module also issues a warning about the fault via a display, indicator light, or remote communication, notifying system administrators to inspect the system. By performing real-time monitoring and fault detection, the fault detection module ensures a rapid response when the system fails, protecting the safety of equipment and personnel, and reducing downtime and repair costs.

[0053] As described above, this system includes a power supply, a cooling fan, and a start / stop control unit. The power supply is equipped with a temperature-sensing element to monitor its internal temperature, the cooling fan is mounted on or inside the power supply case and used to dissipate heat from the power supply, and the start / stop control unit is connected to the cooling fan and temperature-sensing element and is used to control the start and stop of the cooling fan based on the internal temperature of the power supply. Real-time monitoring of the internal temperature of the power supply and smart control of the start and stop of the cooling fan accurately control the power supply temperature, avoid failure trips due to excessively low power supply temperatures, improve equipment stability and reliability, and reduce maintenance costs.

[0054] Figure 2 is a schematic flowchart of a power supply temperature control method according to an embodiment of the present disclosure. As shown in Figure 2, the method includes the following steps.

[0055] Step 101 is to obtain the internal temperature of the power supply.

[0056] In embodiments of the present disclosure, the internal temperature of a power supply can be collected in real time using a temperature-sensing element, this temperature signal can be converted into an electrical signal, and this electrical signal can then be transmitted to a start / stop control unit.

[0057] Step 102 controls the starting and stopping of the cooling fan based on the internal temperature of the power supply, thereby regulating the internal temperature of the power supply.

[0058] In embodiments of the present disclosure, the start-stop control unit compares the internal temperature of the power supply with a preset first temperature threshold based on an internal comparator. If the current internal temperature of the power supply is higher than the first temperature threshold, the comparator outputs a signal instructing the start-stop control unit to start the cooling fan and lower the internal temperature of the power supply. If the current internal temperature of the power supply is below the first temperature threshold, the comparator either does not output a fan start signal or outputs a signal instructing the cooling fan to remain stopped.

[0059] After controlling the cooling fan to a stopped state, the disclosure can reacquire the internal temperature of the power supply at a preset delay time and control the cooling fan.

[0060] Furthermore, this application allows for the acquisition of the internal temperature of the power supply when controlling the cooling fan to the activated state, and dynamically adjusting the rotation speed of the cooling fan if the internal temperature of the power supply is above a second preset temperature threshold. This disclosure also allows for the acquisition of noise data corresponding to the ambient environment, and the adjustment of the fan rotation speed based on the noise data and the internal temperature of the power supply.

[0061] Furthermore, while the cooling fan is operating, the disclosure can acquire the operating parameters of the cooling fan and send a fan alert signal to the fan based on the operating parameters. The disclosure can also monitor the temperature state of the power supply and the operating status of the cooling fan, and issue an alarm if the temperature state of the power supply or the operating status of the cooling fan is abnormal. The disclosure can also acquire the operating status of the start / stop control unit, the cooling fan, and the temperature sensing element, and based on the operating status, protect itself or issue a malfunction warning and notify the system administrator to inspect it. In addition, the disclosure stores the internal temperature of the power supply acquired each time and constructs a power supply temperature change curve using the stored internal temperature of the power supply.

[0062] In summary, the power supply temperature control method according to the embodiment of this disclosure acquires the internal temperature of the power supply, controls the starting and stopping of the cooling fan based on the internal temperature of the power supply, and adjusts the internal temperature of the power supply. Through real-time monitoring of the internal temperature of the power supply and smart control of the starting and stopping of the cooling fan, the power supply temperature is accurately controlled, avoiding failure trips due to excessively low power supply temperatures, improving the stability and reliability of the equipment, and reducing maintenance costs.
