Description
Technical Field
[0001] The present invention relates to the field of amplifiers, and particularly to a heat dissipation control method and control system for a microwave power amplifier. Background Art
[0002] In modern wireless communication systems, as a key component, the performance of a microwave power amplifier is directly related to the coverage range, signal quality, and system stability of the communication system. With the rapid development of communication technologies, the operating frequency and output power of microwave power amplifiers are continuously increasing, which leads to a sharp increase in the heat generated during their operation. Excessive temperature will not only reduce the efficiency of the power amplifier, shorten its service life, but also may cause signal distortion and affect the communication quality. Therefore, effectively controlling the heat dissipation of microwave power amplifiers has become an important issue for improving the performance and reliability of communication systems.
[0003] Traditional heat dissipation control methods for microwave power amplifiers mainly rely on the combination of passive heat dissipation (such as heat sinks, fans, etc.) and active heat dissipation (such as liquid cooling systems) technologies. However, these methods often lack intelligence and self - adaptability and are difficult to dynamically adjust the heat dissipation strategy according to the actual working state of the power amplifier. Especially in complex and changing communication environments, the load, operating frequency, and output power of microwave power amplifiers change frequently, and fixed heat dissipation strategies often cannot meet the actual needs, resulting in poor heat dissipation effects or energy waste.
[0004] In addition, traditional heat dissipation control methods usually ignore the internal relationship between the performance loss of microwave power amplifiers and the heat dissipation effect, and do not make full use of the performance parameters of the power amplifier (such as transmit power, power consumption, temperature, etc.) to optimize the heat dissipation strategy. This not only limits the accuracy and efficiency of heat dissipation control, but also may cause the power amplifier to be in a non - optimal working state for a long time, affecting its long - term stability and reliability.

[0056] As Figure 2 shown, a heat dissipation control system for a microwave power amplifier applies the heat dissipation control method for a microwave power amplifier, and includes a terminal test server, a data processing module, a communication module, a test module, a data acquisition module, an alarm module, and a display module;
[0057] The communication module, the test module, the data acquisition module, the alarm module, and the display module are respectively connected to the data processing module; the terminal test server is communicatively connected to the communication module.
[0058] As Figure 3 shown, the data acquisition module includes a power consumption data acquisition module and a temperature data acquisition module; the power consumption data acquisition module and the temperature data acquisition module are respectively connected to the data processing module.
[0059] Specifically, the method for controlling the heat dissipation of the microwave power amplifier of the present invention specifically includes the following steps:
[0060] Step 1: The terminal test server generates a test control container and connects it to the test module. The test module first conducts a comprehensive test on the microwave power amplifier. By collecting the power consumption data and temperature data at different transmission powers, a relationship curve between the transmission power and the power consumption of the microwave power amplifier and a relationship curve between the transmission power and the temperature of the microwave power amplifier are established. This step is the basis for subsequent analysis, ensuring the accuracy and reliability of the data. At the same time, the test module also conducts a preliminary test on the heat dissipation module of the microwave power amplifier to evaluate its heat dissipation performance and prepare for the subsequent measurement and compensation of the performance attenuation.
[0061] Step 2: According to the relationship between the initial power consumption and the transmission power of the microwave power amplifier obtained in Step 1, calculate the performance loss of the microwave power amplifier. The specific method is that for each transmission power point, calculate the difference between the current power consumption of the microwave power amplifier and the initial power consumption (i.e., the power consumption when the performance has not been lost), and compare it with the initial power consumption to obtain the performance loss percentage. If the performance loss is greater than the set performance loss threshold (such as 5%), an alarm message is sent to prompt the user to perform maintenance or replacement; otherwise, proceed to Step 3.
[0062] Step 3: Analyze the relationship between the transmission power and the temperature of the microwave power amplifier, and compare it with the relationship between the standard transmission power and the temperature of the microwave power amplifier (i.e., the relationship when the performance has not been lost) to obtain the temperature difference of the microwave power amplifier at different transmission powers. According to these temperature differences and the heat dissipation performance of the heat dissipation module (including the fan speed if it is fan heat dissipation, or the coolant flow rate if it is liquid cooling, etc.), calculate the corrected heat dissipation power, that is, the additional heat dissipation power required to make up for the performance loss. Then, add the corrected heat dissipation power to the standard heat dissipation power corresponding to the transmission power to obtain the corrected heat dissipation power corresponding to the transmission power, and evaluate the heat dissipation performance of the microwave power amplifier at different transmission powers, and proceed to Step 5.
[0063] Step 4: The testing module further conducts a detailed test on the heat dissipation module of the microwave power amplifier. By comparing the heat dissipation performance under the standard heat dissipation power and the current heat dissipation power, the performance attenuation of the heat dissipation module is calculated. This data reflects the degree of decline in the heat dissipation capacity of the heat dissipation module due to factors such as aging and wear. Subsequently, the performance attenuation is sent to the calibration module. The calibration module compensates the heat dissipation module according to the relationship between the initial heat dissipation power and the heat dissipation performance of the heat dissipation module, that is, adjusts the corresponding relationship between the heat dissipation power and the heat dissipation performance to offset the influence of performance attenuation, and obtains the relationship between the compensated heat dissipation power and the heat dissipation performance, then enters Step 5.
[0064] Step 5: Based on the results of Step 3 and Step 4, for each transmit power point, the corresponding compensated heat dissipation power is matched in the relationship between the compensated heat dissipation power and the heat dissipation performance according to the heat dissipation performance of the microwave power amplifier (the heat dissipation requirement considering performance loss). In this way, the compensated heat dissipation power corresponding to the heat dissipation performance at different transmit powers is obtained, which together with the corresponding transmit power constitutes the heat dissipation strategy of the power amplifier. This strategy ensures that the microwave power amplifier can obtain just the right heat dissipation support under different working conditions.
[0065] Step 6: Finally, according to the heat dissipation strategy of the power amplifier, the working state of the heat dissipation module (such as fan speed, coolant flow, etc.) is adjusted in real time through the control system to precisely dissipate heat from the power amplifier. At the same time, the system can continuously monitor the working state and heat dissipation effect of the microwave power amplifier, and automatically adjust the heat dissipation strategy when necessary to achieve closed-loop control and ensure the effectiveness and stability of heat dissipation control.
[0066] The specific implementation method for the testing module to test the microwave power amplifier:
[0067] The testing module collects the power consumption and temperature data of the microwave power amplifier at different transmit powers through a data acquisition module (including a power consumption data acquisition module and a temperature data acquisition module). The power consumption data acquisition module measures the input power and output power of the power amplifier using a high-precision power meter and calculates the power consumption; the temperature data acquisition module directly measures the working temperature of the power amplifier through a temperature sensor.
[0068] The specific implementation method for the testing module to test the heat dissipation module of the microwave power amplifier:
[0069] The performance attenuation test of the heat dissipation module is mainly based on the change in heat dissipation efficiency. During the test, a series of standard heat dissipation power values are first set, and the temperature of the microwave power amplifier that the heat dissipation module can maintain at these powers is measured. Then, it is compared with the actual heat dissipation performance during operation, and the performance attenuation of the heat dissipation module is obtained by calculating the difference in the required heat dissipation power under the same heat dissipation effect.
[0070] The specific implementation method for obtaining the performance loss of the microwave power amplifier based on the relationship between the initial power consumption and the transmission power of the microwave power amplifier:
[0071] The calculation of performance loss adopts the relative value comparison method. For each transmission power point, calculate the difference between the current power consumption and the initial power consumption (usually measured when the power amplifier leaves the factory or when its performance is optimal), and divide this difference by the initial power consumption to obtain the performance loss percentage. This method can intuitively reflect the degree of degradation of the power amplifier's performance over time.
[0072] The specific implementation method for obtaining the corrected heat dissipation power based on the temperature difference:
[0073] The relationship between the standard transmission power and the temperature of the microwave power amplifier is determined through experiments or data provided by the manufacturer, representing the operating temperature characteristics of the power amplifier under ideal conditions. In actual applications, by comparing the current operating temperature with the standard temperature, the temperature difference is obtained. Then, according to the heat dissipation performance of the heat dissipation module, calculate the additional heat dissipation power required to eliminate this temperature difference, that is, the corrected heat dissipation power.
[0074] The specific implementation method for the calibration module to compensate the heat dissipation module:
[0075] The calibration module corrects the original relationship between the heat dissipation power and the heat dissipation performance according to the performance attenuation amount of the heat dissipation module. The specific approach is to, on the basis of the original relationship curve, adjust the heat dissipation power value upward according to the proportion of the performance attenuation amount to ensure that the heat dissipation module can provide sufficient heat dissipation capacity under the same heat dissipation performance requirements.
[0076] The heat dissipation control system of the microwave power amplifier of the present invention includes a terminal test server, a data processing module, a communication module, a test module, a data acquisition module (including a power consumption data acquisition module and a temperature data acquisition module), an alarm module, and a display module. Among them, the communication module is responsible for data transmission between the terminal test server and the local system; the test module is responsible for executing specific test tasks; the data acquisition module is responsible for collecting the operating parameters of the microwave power amplifier and the heat dissipation module; the data processing module is responsible for data processing, analysis, and strategy generation; the alarm module issues an alarm when detecting an abnormal situation; the display module is used to display the test results and heat dissipation strategies. Embodiment
[0077] The microwave power amplifier used in a certain communication base station needs heat dissipation control to ensure its stable operation at different transmission powers.
[0078] Specific steps:
[0079] Step 1: The terminal test server generates a test control container and connects it to the test module in the base station. The test module conducts a comprehensive test on the microwave power amplifier through the data acquisition module (including the power consumption data acquisition module and the temperature data acquisition module). The power consumption data acquisition module measures the input power and output power of the power amplifier at multiple transmit power points (such as 10W, 20W, 30W, etc.) using a high-precision power meter, and calculates the corresponding power consumption. The temperature data acquisition module measures the operating temperature at these transmit powers through temperature sensors installed on the power amplifier.
[0080] Based on these data, the relationship curves of transmit power vs. power consumption and transmit power vs. temperature of the microwave power amplifier are established.
[0081] Meanwhile, a preliminary test is conducted on the heat dissipation module (assumed to be fan heat dissipation), and the heat dissipation effects at different fan speeds are recorded.
[0082] Step 2: The data processing module calculates the percentage of performance loss at each transmit power point based on the power consumption data obtained in Step 1. For example, at a transmit power of 20W, the current power consumption is 3% higher than the initial power consumption, which is lower than the set performance loss threshold of 5%, so no alarm message is sent.
[0083] Step 3: Analyze the relationship between transmit power and temperature and compare it with the standard relationship. It is found that at a transmit power of 30W, the actual operating temperature of the microwave power amplifier is 5°C higher than the standard temperature. According to the heat dissipation performance of the fan heat dissipation module (the relationship between fan speed and heat dissipation effect), the additional heat dissipation power required to make up for this 5°C temperature difference, that is, the corrected heat dissipation power, is calculated. The corrected heat dissipation power is obtained by adding the corrected heat dissipation power to the standard heat dissipation power at 30W transmit power.
[0084] Step 4: The test module conducts a detailed test on the fan heat dissipation module and finds that due to fan aging, its heat dissipation efficiency has decreased by 10%. The calibration module corrects the original relationship between heat dissipation power and heat dissipation performance based on this performance attenuation amount, and increases the heat dissipation power value required for the same heat dissipation effect.
[0085] Step 5: For each transmit power point, according to the heat dissipation performance of the microwave power amplifier (the requirements after considering performance loss and heat dissipation module attenuation), the corresponding compensated heat dissipation power is matched in the relationship between compensated heat dissipation power and heat dissipation performance. A heat dissipation strategy for the power amplifier is formed. For example, at a transmit power of 30W, the fan needs to operate at a specific speed to ensure the heat dissipation effect.
[0086] Step 6: The control system adjusts the fan speed in real time according to the heat dissipation strategy to precisely dissipate heat from the microwave power amplifier. The system continuously monitors the operating status and heat dissipation effect of the power amplifier and automatically adjusts the fan speed when necessary to ensure the effectiveness and stability of heat dissipation control.
