Description

Technical Field

[0001] The present application relates to the field of heat exchange and cooling of a test machine, and in particular to an intelligent heat exchange system, a vehicle and a switching control method thereof. Background Art

[0002] The heat exchange and cooling of the test machine mainly rely on the heat exchanger and the corresponding cooling system. The heat exchanger is a key device for realizing heat transfer between different media. It transfers the heat of the high-temperature fluid to the low-temperature fluid through heat conduction and convection, realizes heat recovery and reuse, and thus improves energy utilization efficiency. In refrigeration equipment, such as water-cooled chillers, heat exchangers are used to absorb and discharge heat to maintain the normal operation of the system. At the same time, according to the cooling requirements, the cooling system can adopt direct liquid cooling, indirect liquid cooling, natural liquid cooling or forced liquid cooling to achieve efficient heat transfer and cooling effects. In summary, the heat exchange and cooling process of the test machine is inseparable from the synergy of the heat exchanger and the cooling system, which together ensure the efficient and stable operation of the test machine.

[0003] In the related technology, the traditional heat exchange system mainly uses the heat exchanger as the carrier, and uses cooling water to cool the test machine. The industry usually selects the heat exchanger based on the maximum heat dissipation, and then considers the design margin, and often selects a larger heat exchanger. Because the influence of the cooling water temperature was not considered when the heat exchanger system was designed, the developed heat exchange system is prone to "overheating in summer and overcooling in winter" during use. This means that in summer, the cooling water temperature is relatively high, and a large-flow heat exchanger can meet the heat dissipation requirements of the test machine; in winter, the cooling water temperature is lower. If the heat exchanger continues to be used, the test machine will not be able to work normally due to overcooling. Summary of the invention

[0004] The present application provides an intelligent heat exchange system, a vehicle and a switching control method thereof, which can realize automatic switching of the heat exchanger according to the cooling water temperature, enhance the system's adaptability to different ambient temperatures, ensure the stable operation of the test machine throughout the year, and effectively solve the problem of "overheating in summer and overcooling in winter" that the test machine is prone to in traditional heat exchange systems.

[0040] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0041] The embodiments of the present application provide an intelligent heat exchange system, a vehicle and a switching control method thereof, which can realize automatic switching of the heat exchanger according to the cooling water temperature, enhance the system's adaptability to different ambient temperatures, ensure the stable operation of the test machine throughout the year, and effectively solve the problem of "overheating in summer and overcooling in winter" that the test machine is prone to in traditional heat exchange systems.

[0042] First, as Figure 1As shown, an embodiment of the present application provides an intelligent heat exchange system, which includes: a cooling water supply system 1, wherein the cooling water supply system 1 is equipped with a temperature sensor 2, and a pipeline 3 is connected in series between the output end and the input end of the cooling water supply system 1, and the pipeline 3 is equipped with a heat exchanger 4 and a valve 5; a pipeline 2 6, wherein the pipeline 2 6 is connected in parallel with the pipeline 1 3, and the pipeline 2 6 is equipped with a heat exchanger 2 7 and a valve 2 8, and the heat exchange capacity of the heat exchanger 2 7 is less than the heat exchange capacity of the heat exchanger 1 4; a controller, wherein the controller is signal-connected with the cooling water supply system 1, the valve 1 5 and the valve 2 8; the controller is used to open the valve 1 5 and close the valve 2 8 when the temperature value of the cooling water before the operation monitored by the temperature sensor 2 is greater than the preset temperature value, or control the closing of the valve 1 5 and the opening of the valve 2 8 when the temperature value of the cooling water before the operation monitored by the temperature sensor 2 is less than or equal to the preset temperature value.

[0043] In this embodiment, the temperature sensor 2 installed in the cooling water supply system 1 monitors the temperature of the cooling water in real time. The temperature sensor 2 transmits the monitored temperature value to the controller in real time. Pipeline 1 3 and pipeline 2 6 are connected in parallel, and are respectively equipped with heat exchangers with different heat exchange capacities. The heat exchange capacity of heat exchanger 1 4 is relatively strong and is suitable for high temperature environments (such as summer). The heat exchange capacity of heat exchanger 2 7 is relatively weak and is suitable for low temperature environments (such as winter). The controller compares the temperature value fed back by the temperature sensor 2 with the preset temperature value. When the temperature value is higher than the preset temperature value (such as summer), the controller sends a signal to open valve 1 5 and close valve 2 8, so that the cooling water passes through pipeline 1 3 and heat exchanger 1 4 to adapt to heat exchange. When the temperature value is lower than or equal to the preset temperature value, the controller sends a signal to close valve 1 5 and open valve 2 8, so that the cooling water passes through pipeline 2 6 and heat exchanger 2 7 to adapt to heat exchange to prevent the sample machine from being overcooled. Through intelligent control and dual-pipeline design, the system can automatically adjust the heat exchange efficiency according to the ambient temperature to ensure that the sample machine can be maintained within a suitable operating temperature range in different seasons throughout the year. It avoids the problem of "overheating in summer and overcooling in winter" caused by traditional heat exchange systems that do not consider the influence of cooling water temperature. It improves the stability and energy efficiency of the system and reduces unnecessary energy waste.

[0044] For example, the ambient temperature is usually between 0℃ and 40℃ throughout the year, and the interval of 10℃ can be divided into: 10℃, 20℃, 30℃, 40℃. 10℃ and 20℃ are defined as winter environment, and the average temperature value of winter environment is 15℃; 30℃ and 40℃ are defined as summer environment, and the average temperature value of summer environment is 35℃, and the cooling water temperature is measured in real time. Here, the preset temperature value is defined as 20℃. When the cooling water temperature is lower than 20℃, it is executed according to pipeline 26 and heat exchanger 27; when the cooling water temperature is higher than 20℃, it is executed according to pipeline 13 and heat exchanger 14.

[0045] In combination with the first aspect, in one embodiment, the pipeline 1 3 is installed with valve 3 9 and valve 4 10, and the valve 1 5 and valve 2 8 are both located between the valve 3 9 and the valve 4 10; the intelligent heat exchange system includes: a cleaning device 11, the input and output ends of the cleaning device 11 are connected between the valve 3 9 and the valve 4 10, and are connected in parallel with the pipeline 1 3 and the pipeline 2 6; the controller is signal-connected to the valve 3 9 and the valve 4 10; the controller is used to control the closing of the valve 3 9 and the valve 4 10, and the opening of the valve 1 5 and the valve 2 8 when the cleaning device 11 needs to work.

[0046] In this embodiment, valve three 9 and valve four 10 are added to pipeline one 3, and the input and output ends of the cleaning device 11 are connected between valve three 9 and valve four 10, forming a cleaning loop in parallel with pipeline one 3 and pipeline two 6. When the cleaning device 11 needs to work (for example, the heat exchanger is cleaned regularly to maintain its heat exchange efficiency), the controller sends a signal to close valve three 9 and valve four 10 to cut off the flow of cooling water in pipeline one 3. At the same time, the controller opens valve one 5 and valve two 8, so that the cleaning device 11 can clean heat exchanger one 4 and heat exchanger two 7 through pipeline one 3 and pipeline two 6. During the cleaning process, the cleaning device 11 contains a cleaning agent or a high-pressure water flow, etc., which is used to remove dirt and sediment on the surface of the heat exchanger, thereby restoring its heat exchange performance. By adding a cleaning device 11 and corresponding valve control logic, the intelligent heat exchange system can not only automatically adjust the heat exchange efficiency according to the ambient temperature, but also clean the heat exchanger regularly to ensure that it maintains efficient heat exchange performance for a long time. This helps to extend the service life of the heat exchanger and reduce the loss of heat exchange efficiency and energy waste caused by dirt deposition. The automatic control of the cleaning function also improves the maintenance convenience and operational reliability of the system.

[0047] In combination with the first aspect, in one embodiment, the cleaning device 11 includes: a cleaning pipeline 1101, the input end and the output end of the cleaning pipeline 1101 are connected between the valve three 9 and the valve four 10, and are connected in parallel with the pipeline one 3 and the pipeline two 6; a water tank 1102, a water pump 1103 and a metering unit 1104, the water tank 1102, the water pump 1103 and the metering unit 1104 are connected in sequence and installed on the cleaning pipeline 1101; a valve five 1105 and a valve six 1106, the valve five 1105 and the valve six 1106 are installed on the cleaning pipeline 1101, and the water tank 1102, the water pump 1103 and the metering unit 1104 are located between the valve five 1105 and the valve six 1106.

[0048] In this embodiment, the cleaning device 11 mainly includes a cleaning pipeline 1101, a water storage tank 1102, a water pump 1103, a metering unit 1104, a valve five 1105 and a valve six 1106. The input end and the output end of the cleaning pipeline 1101 are connected between the valve three 9 and the valve four 10, and are connected in parallel with the pipeline one 3 and the pipeline two 6 to form a cleaning loop. The water storage tank 1102 is used to store water or cleaning agents required for cleaning. The water pump 1103 is responsible for pumping the water or cleaning agents in the water storage tank 1102 into the cleaning pipeline 1101. The metering unit 1104 is used to measure and control the flow of the cleaning fluid to ensure the accuracy and effectiveness of the cleaning process. The valve five 1105 and the valve six 1106 are installed on the cleaning pipeline 1101 to control the flow direction and flow state of the cleaning fluid. When the cleaning device 11 needs to work, the controller sends a signal to close the valve three 9 and the valve four 10 to cut off the flow of cooling water in the pipeline one 3. At the same time, the controller opens valve five 1105 and valve six 1106, so that the cleaning fluid can clean the heat exchanger one 4 and the heat exchanger two 7 through the cleaning pipeline 1101. The water pump 1103 starts to pump the water or cleaning agent in the water tank 1102 into the cleaning pipeline 1101, and controls the flow rate through the metering unit 1104. The cleaning fluid circulates in the cleaning pipeline 1101 to clean the heat exchanger and remove dirt and sediment. It can ensure that the heat exchanger maintains efficient heat exchange performance for a long time. The combined use of the water tank 1102, the water pump 1103 and the metering unit 1104 makes the cleaning process more controllable and reliable, reducing waste and unnecessary energy consumption in the cleaning process.

[0049] In combination with the first aspect, in one embodiment, the intelligent heat exchange system includes: pressure sensor 1 and pressure sensor 2, wherein the pressure sensor 1 and the pressure sensor 2 are installed on the pipeline 1 3, and the heat exchanger 1 4 is located between the pressure sensor 1 and the pressure sensor 2; the controller is used to control the cleaning device 11 to work, close the valve 3 9 and the valve 4 10, and open the valve 1 5 and the valve 2 8 when the pressure difference between the pressure sensor 1 and the pressure sensor 2 is greater than the preset pressure difference, and the measured value of the operating temperature of the tested sample is greater than the preset target temperature.

[0050] In this embodiment, pressure sensor 1 and pressure sensor 2 are installed on pipeline 1 3 to monitor pressure changes. Heat exchanger 1 4 is located between the two pressure sensors and is responsible for heat exchange. The controller performs control according to the data of the pressure sensor and the temperature sensor (monitoring the operating temperature of the tested sample). When the pressure difference between pressure sensors 1 and 2 and the operating temperature of the tested sample exceed the preset value, it means that the pipeline of the heat exchange system is blocked and the operation is abnormal and needs to be cleaned. The controller starts the cleaning device 11, closes valve 3 9 and valve 4 10 at the same time, opens valve 1 5 and valve 2 8, and cleans pipeline 1 3 and pipeline 2 6 at the same time. The efficient and stable operation of the intelligent heat exchange system is ensured, and the optimized management of the heat exchange process is achieved by precisely controlling the coordinated work of each component.

[0051] In combination with the first aspect, in one embodiment, the intelligent heat exchange system includes: pressure sensor three and pressure sensor four, the pressure sensor three and the pressure sensor four are installed on the pipeline two 6, and the heat exchanger two 7 is located between the pressure sensor three and the pressure sensor four, and the controller is used to control the cleaning device 11 to work, control the valve three 9 and the valve four 10 to close, and control the valve one 5 and the valve two 8 to open when the pressure difference between the pressure sensor three and the pressure sensor four is greater than the preset pressure difference and the measured value of the operating temperature of the tested sample is greater than the preset target temperature.

[0052] In this embodiment, the specific working principle refers to pressure sensor 1 and pressure sensor 2 to detect and judge the blockage of pipeline 2 6. If it is determined that there is blockage, the cleaning device 11 is started to flush and clean pipeline 1 3 and pipeline 2 6.

[0053] In a second aspect, an embodiment of the present application provides a vehicle, which includes an intelligent heat exchange system as described in some of the above embodiments.

[0054] In a third aspect, the embodiments of the present application provide a switching control method of the intelligent heat exchange system as described in some of the above embodiments, which comprises the following steps:

[0055] S100: Real-time acquisition of the temperature value of the cooling water collected by the temperature sensor 2 before the cooling water supply system 1 works;

[0056] S200: If it is determined that the temperature value of the cooling water monitored by the temperature sensor 2 is greater than the preset temperature value, then control is performed to open valve 1 5 and close valve 2 8 to make the heat exchanger 1 4 work; if it is determined that the temperature value of the cooling water monitored by the temperature sensor 2 is less than or equal to the preset temperature value, then control is performed to close valve 1 5 and open valve 2 8 to make the heat exchanger 2 7 work.

[0057] In this embodiment, the temperature sensor 2 installed in the cooling water supply system 1 monitors the temperature of the cooling water in real time. The temperature sensor 2 transmits the monitored temperature value to the controller in real time. Pipeline 1 3 and pipeline 2 6 are connected in parallel, and are respectively equipped with heat exchangers with different heat exchange capacities. The heat exchange capacity of heat exchanger 1 4 is relatively strong and is suitable for high temperature environments (such as summer). The heat exchange capacity of heat exchanger 2 7 is relatively weak and is suitable for low temperature environments (such as winter). The controller compares the temperature value fed back by the temperature sensor 2 with the preset temperature value. When the temperature value is higher than the preset temperature value (such as summer), the controller sends a signal to open valve 1 5 and close valve 2 8, so that the cooling water passes through pipeline 1 3 and heat exchanger 1 4 to adapt to heat exchange. When the temperature value is lower than or equal to the preset temperature value, the controller sends a signal to close valve 1 5 and open valve 2 8, so that the cooling water passes through pipeline 2 6 and heat exchanger 2 7 to adapt to heat exchange to prevent the sample machine from being overcooled. Through intelligent control and dual-pipeline design, the system can automatically adjust the heat exchange efficiency according to the ambient temperature to ensure that the sample machine can be maintained within a suitable operating temperature range in different seasons throughout the year. It avoids the problem of "overheating in summer and overcooling in winter" caused by traditional heat exchange systems that do not consider the influence of cooling water temperature. It improves the stability and energy efficiency of the system and reduces unnecessary energy waste.

[0058] Further, in one embodiment, after S200, the following steps are included:

[0059] S300: If the pressure difference before and after the monitored heat exchanger 4 is greater than the preset pressure difference, and the measured value of the operating temperature of the tested sample is greater than the preset target temperature, the cleaning device 11 is controlled to work, and the valve three 9 and the valve four 10 are closed.

[0060] In this embodiment, pressure sensors are arranged before and after the heat exchanger 4 to monitor the pressure difference before and after it in real time. At the same time, the actual measured value of the operating temperature of the tested sample is obtained and compared with the preset target temperature value. When the pressure difference before and after the heat exchanger exceeds the preset value, and the actual measured value of the operating temperature of the tested sample is higher than the target temperature value, the controller sends a signal to control the cleaning device 11 to start working, and at the same time closes the valves related to the cleaning device (such as valve three 9 and valve four 10) to ensure the effective implementation of the cleaning process and the safety of the system. By cleaning the heat exchanger regularly or on demand, the dirt and blockage inside it are removed to maintain its efficient heat exchange performance. Avoid abnormal system pressure and decreased heat exchange efficiency caused by blockage of the heat exchanger, thereby improving the overall stability of the system. Ensuring that the heat exchanger always works in the best condition helps to optimize the energy efficiency of the entire cooling water supply system. Regular cleaning of the heat exchanger can reduce its wear and corrosion, thereby extending its service life.

[0061] Further, in one embodiment, after S200, the following steps are included:

[0062] S400: If the pressure difference before and after the monitored heat exchanger 2 7 is greater than the preset pressure difference, and the measured value of the operating temperature of the tested sample is greater than the preset target temperature, the cleaning device 11 is controlled to work and the valve 3 9 and the valve 4 10 are closed.

[0063] In this embodiment, pressure sensors are arranged before and after the heat exchanger 2 7 to monitor the pressure difference before and after it in real time. At the same time, the actual measured value of the operating temperature of the tested sample is obtained and compared with the preset target temperature value. When the pressure difference before and after the heat exchanger exceeds the preset value, and the actual measured value of the operating temperature of the tested sample is higher than the target temperature value, the controller sends a signal to control the cleaning device 11 to start working, and at the same time closes the valves related to the cleaning device (such as valve three 9 and valve four 10) to ensure the effective implementation of the cleaning process and the safety of the system. By cleaning the heat exchanger regularly or on demand, the dirt and blockage inside it are removed to maintain its efficient heat exchange performance. Avoid abnormal system pressure and decreased heat exchange efficiency caused by blockage of the heat exchanger, thereby improving the overall stability of the system. Ensuring that the heat exchanger always works in the best condition helps to optimize the energy efficiency of the entire cooling water supply system. Regular cleaning of the heat exchanger can reduce its wear and corrosion, thereby extending its service life.

[0064] Further, in one embodiment, after S200, the following steps are included:

[0065] S500: If the pressure difference before and after the monitored heat exchanger 2 7 is less than the preset pressure difference, and the measured value of the operating temperature of the tested sample is greater than the preset target temperature, then the cooling water flow supply insufficient warning of the cooling water supply system 1 is triggered.

[0066] In this embodiment, the pressure difference before and after the heat exchanger 2 7 is less than the preset value, and the actual temperature value of the prototype exceeds the standard. The cooling water supply system 1 is warned of insufficient cooling water flow. Step S500 is an important part of the heat exchanger monitoring system, ensuring that when the pressure difference is abnormally low and the temperature of the prototype is too high, a warning of insufficient cooling water supply can be issued in time. This helps to ensure the stable operation of the system and avoid equipment damage or performance degradation due to insufficient cooling. Through this step, potential cooling system problems can be discovered and dealt with in a timely manner to ensure the safety and reliability of the entire system.
