[0002] Thermal management is a crucial technology for ensuring the proper functioning and extended lifespan of electronic equipment, machinery, and various industrial and consumer products. Excessive temperatures can degrade equipment performance, damage components, and even cause fires. Thermal management prevents overheating and ensures safe operation. Furthermore, equipment operating at suitable temperatures is more reliable, and thermal management helps reduce temperature-related failures and system outages.

[0003] With the increasing popularity of electric vehicles and high-power devices, the demand for high-power charging technology is growing. Charging modules generate heat during charging, especially under high-current fast charging conditions. Overheating can lead to derating, shutdown, or even fire. Furthermore, existing technologies suffer from limitations such as a single flow distribution method in the thermal management system, high energy consumption during fan and pump operation, and significant noise levels. Summary of the Invention

[0004] In view of this, the purpose of this application is to provide a cooling system that can improve the problems of single flow distribution method, high energy consumption and high noise during operation of fan speed and water pump speed in the prior art.

[0007] The monitoring device is electrically connected to the control valve; the monitoring device is configured to monitor the ambient temperature and the temperature parameters of the heat-loaded equipment and obtain thermal monitoring data;

[0008] The control valve is connected to the flow channel; the control valve controls its opening and closing degree based on the thermal monitoring data, so as to control the total amount of heat exchange medium in the flow channel.

[0009] In the above implementation process, the flow channel in the fluid transport unit provides a channel for the transmission of the heat exchange medium; the flow channel is connected to the heat load equipment and uses the heat exchange medium in the flow channel to exchange heat with the heat load equipment; the monitoring equipment monitors parameters such as ambient temperature and heat load equipment temperature and obtains thermal monitoring data. The monitoring equipment transmits the monitored data to the control valve through an electrical connection. The control valve automatically adjusts its opening and closing degree according to the received thermal monitoring data to control the flow rate of the heat exchange medium in the flow channel, so as to meet the needs of different heat loads.

[0010] Optionally, the fluid transport unit further includes: a fluid transport pump; the fluid transport pump is connected to the flow channel; the fluid transport pump is configured to pump a heat exchange medium within the flow channel; and the fluid transport pump controls its pumping speed based on the thermal monitoring data.

[0011] In the above process, the fluid transport pump is responsible for pumping the heat exchange medium within the flow channel, driving its circulation in the cooling system to assist in heat transfer. Based on thermal monitoring data provided by the monitoring equipment, the fluid transport pump dynamically adjusts its pumping speed to adapt to temperature changes in the heat-loaded equipment, while simultaneously optimizing heat exchange efficiency.

[0012] Optionally, the flow channel is also connected to a fluid storage unit; the fluid storage unit stores a heat exchange medium; the heat exchange medium circulates in the flow channel based on the transport of the fluid transport pump.

[0013] In the above implementation process, the flow channel is connected not only to the heat load equipment but also to the fluid storage unit, forming a complete circulation system. The fluid storage unit stores heat exchange media, such as coolant, providing the system with the necessary working fluid for heat exchange. The fluid storage unit ensures that there is always sufficient heat exchange media circulating in the system, guaranteeing continuous system operation.

[0014] Optionally, there are multiple flow channels; multiple flow channels are connected in parallel to multiple heat load modules in the heat load device; and the control valve is connected to the corresponding heat load module.

[0015] In the above implementation process, the cooling system is designed with multiple flow channels, which are connected in parallel to multiple heat load modules in the heat load equipment to achieve more uniform and efficient heat exchange. Through multiple parallel flow channels, the heat exchange medium can be evenly distributed to each heat load module, ensuring that each module receives appropriate cooling.

Conversely, when the monitoring equipment detects that the heat load module is in an inactive state, i.e., the module is not currently working and is not generating significant heat, the control valve will automatically close. This configuration of the control valve allows the system to control the flow rate of the heat exchange medium through each heat load module according to the actual heat load requirements of that module.

[0020] Optionally, the cooling system further includes: a heat dissipation unit connected to the flow channel; the heat dissipation unit is in communication with the outside; wherein, based on the connection between the heat dissipation unit and the flow channel, the heat exchange medium passes from the flow channel through the heat dissipation unit; the heat dissipation unit is configured to exchange heat with the outside through the heat exchange medium flowing through the heat dissipation unit.

[0021] In the above process, the heat dissipation unit is connected to the flow channel, the heat exchange medium flows in the flow channel, and passes through the heat dissipation unit connected to the flow channel, thereby transferring the heat absorbed from the heat load module to the heat dissipation unit. The heat dissipation unit dissipates the heat in the heat exchange medium to the external environment, thereby achieving thermal balance and stable operation of the entire system.

[0022] Optionally, the heat dissipation unit includes: a radiator and heat dissipation blades; the heat dissipation blades are mounted on one side of the radiator and are positioned towards the radiator; the heat dissipation blades are configured to adjust their rotational speed based on the thermal monitoring data.

[0023] In the above implementation process, the heat dissipation unit consists of a radiator and cooling fins (usually referring to a fan), working together to improve the heat dissipation efficiency of the heat exchange medium. The cooling fins are mounted on one side of the radiator, typically to effectively direct or pass air towards the radiator, enhancing heat dissipation. The cooling fins are positioned facing the radiator to ensure optimized airflow and improve heat dissipation efficiency. When the temperature of the heat-loaded module rises, the speed of the cooling fins increases to enhance heat dissipation; when the temperature decreases, the speed decreases to save energy. Adjusting the speed of the cooling fins also helps balance noise levels and heat dissipation performance to meet the requirements of different environments. The operation of the heat dissipation unit relies on an intelligent control system that automatically adjusts based on real-time data, improving operational convenience and system reliability.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of the embodiments of this application.

[0032] Please see Figure 1 , Figure 1 This is a simplified schematic diagram of a cooling system provided in an embodiment of this application.

[0033] The cooling system includes a fluid transport unit, a control valve 200, and a monitoring device 300. The fluid transport unit includes a flow channel 100, which is configured to provide a channel for the transmission of the heat exchange medium. The flow channel 100 is connected to the heat load device 400 and performs heat exchange on the heat load device 400 based on the heat exchange medium therein. The monitoring device 300 is electrically connected to the control valve 200. The monitoring device 300 is configured to monitor parameters such as ambient temperature and the temperature of the heat load device 400 and obtain thermal monitoring data. The control valve 200 is connected to the flow channel 100. Based on the thermal monitoring data, the control valve 200 controls its opening and closing degree to control the total amount of heat exchange medium in the flow channel 100.

[0034] In the above implementation process, the flow channel 100 in the fluid transport unit provides a channel for the transmission of the heat exchange medium; the flow channel 100 is connected to the heat load device 400, and heat exchange is carried out between the heat exchange medium in the flow channel 100 and the heat load device 400; the monitoring device 300 monitors parameters such as ambient temperature and the temperature of the heat load device 400, and obtains thermal monitoring data. The monitoring device 300 transmits the monitored data to the control valve 200 through an electrical connection (which may be wired or wireless). The control valve 200 automatically adjusts its opening and closing degree according to the received thermal monitoring data to control the flow rate of the heat exchange medium in the flow channel 100, so as to meet the needs of different heat loads.

[0035] Optionally, when the monitoring device 300 detects that the heat load module 410 is in a called state, the control valve 200 is opened to the intermediate opening degree; if the monitoring device 300 detects that the heat load module 410 is in an uncalled state, the control valve 200 is closed.

[0036] Optionally, the heat load device 400 can be any device requiring cooling, such as: power electronic equipment like frequency converters, inverters, power converters, etc.; computers and servers; batteries and motors of electric vehicles, energy converters of hybrid power systems, etc. Optionally, the flow channel 100 can be designed as a parallel flow channel 100 to increase the flow rate and heat exchange area of ​​the heat exchange medium and improve cooling efficiency; the material and surface treatment of the flow channel 100 can resist the chemical corrosion of specific cooling media; the flow channel 100 is designed to withstand high-temperature cooling media and is suitable for high-temperature working environments.

[0037] Preferably, the flow channel 100 can also be connected to a filter, which is disposed in the cooling circuit. The filter contains filter media, such as metal mesh, filter paper, microporous filter membrane, etc., which can intercept solid particles and impurities in the cooling media to protect the system from contamination and clogging.

[0038] The control valve 200 is configured to open when the monitoring device 300 detects that the heat load module 410 is in an activated state, and to close when the monitoring device 300 detects that the heat load module 410 is in an unactivated state.

[0039] In the above implementation process, when the monitoring device 300 detects that the heat load module 410 is in an activated state, i.e., the module is working and generating heat, the control valve 200 will automatically open. Conversely, when the monitoring device 300 detects that the heat load module 410 is in an inactive state, i.e., the module is not currently working and is not generating significant heat, the control valve 200 will automatically close. This configuration of the control valve 200 allows the system to control the flow rate of the heat exchange medium through each heat load module 410 according to the actual heat load requirements of that module. This configuration helps improve the efficiency of the entire cooling system, and heat exchange resources can be more rationally allocated to the modules that need them.

[0040] Please see Figure 2 , Figure 2 A schematic diagram of the cooling system provided in the embodiments of this application.

[0041] The fluid transport unit also includes: a fluid transport pump 110; the fluid transport pump 110 is connected to the flow channel 100; the fluid transport pump 110 is configured to transport the heat exchange medium within the pumping flow channel 100; and the fluid transport pump 110 controls its pumping speed based on thermal monitoring data.

[0042] In the above process, the fluid transport pump 110 is responsible for pumping the heat exchange medium within the flow channel 100, driving it to circulate in the cooling system to assist in heat transfer. Based on the thermal monitoring data provided by the monitoring equipment 300, the fluid transport pump 110 dynamically adjusts its pumping speed to adapt to temperature changes in the heat-loaded equipment 400, while simultaneously optimizing heat exchange efficiency.

[0043] In one embodiment of this application, it is assumed that the total number of heat load modules is M0, and M0 > 1. The number of modules called is denoted by M, where high load is M > M1, medium load is M1 ≥ M ≥ M2, and low load is M < M2; the ambient temperature is assumed to be Temp, where high temperature is Temp > Temp1, normal temperature is Temp1 ≥ Temp ≥ Temp2, and low temperature is Temp < Temp2; the temperature of the called modules is denoted by T, where high temperature is T > T1, medium temperature is T1 ≥ T ≥ T2, and low temperature is T < T2. The pumping speed is denoted by n, corresponding to different numbers of called heat load modules, the temperatures of the called heat load modules, and the ambient temperature, with ranges of n0, n1, n2, ..., n27.

[0044] Optionally, the fluid transport pump 110 can be designed with multi-stage pumping capability to adapt to different system pressure and flow requirements. The fluid transport pump 110 can change its pumping speed according to the temperature of the heat exchange medium or the number of heat load modules 410 called.

[0045] The flow channel 100 is also connected to a fluid storage unit 120; the fluid storage unit 120 stores a heat exchange medium; the heat exchange medium circulates in the flow channel 100 based on the transport of the fluid transport pump 110.

[0046] In the above implementation process, the flow channel 100 is not only connected to the heat load device 400, but also to the fluid storage unit 120, forming a complete circulation system. The fluid storage unit 120 stores heat exchange media, such as coolant, to provide the system with the necessary heat exchange working fluid. The fluid storage unit 120 ensures that there is always enough heat exchange media circulating in the system, guaranteeing continuous operation of the system.

[0047] Optionally, the fluid storage unit 120 may be equipped with a pressure relief device to prevent pressure buildup due to temperature changes or other reasons; the fluid storage unit 120 may integrate a flow regulating device to allow control of the flow rate of the heat exchange medium between the storage unit and the flow channel 100. The system can select different types of heat exchange media, such as water-glycol mixtures, mineral oils, or other special liquids, to suit specific temperature ranges or chemical environments.

[0048] There are multiple flow channels 100; multiple flow channels 100 are connected in parallel to multiple heat load modules 410 in the heat load device 400; and control valves 200 are connected to the corresponding heat load modules 410. A heat exchanger is provided inside the heat load module 410; the heat exchanger is connected to the flow channel 100 and is used for heat exchange with the heat exchange medium.

[0049] In the above implementation process, the cooling system is designed with multiple flow channels 100, which are connected in parallel to multiple heat load modules 410 in the heat load device 400 to achieve more uniform and efficient heat exchange. Through the multiple parallel flow channels 100, the heat exchange medium can be evenly distributed to each heat load module 410, ensuring that each module receives appropriate cooling. Each heat load module 410 is connected to a control valve 200, allowing independent control of the cooling requirements of each module. The system can dynamically adjust the opening and closing degree of each control valve 200 according to the specific heat load of each heat load module 410 to adapt to different cooling needs. The heat load module 410 integrates a heat exchanger, enabling it to directly exchange heat with the heat exchange medium in the flow channels 100, while ensuring that heat is effectively transferred from the heat load module 410 to the medium.

[0050] Optionally, the heat exchanger may employ an optimized flow channel 100 design, such as a microchannel or finned structure, to improve heat exchange efficiency. The control valve 200 is configured to open when the monitoring device 300 detects that the heat load module 410 is in an activated state, and to close when the monitoring device 300 detects that the heat load module 410 is in an inactive state.

[0051] In the above implementation process, when the monitoring device 300 detects that the heat load module 410 is in an activated state, i.e., the module is working and generating heat or current is flowing through it, the control valve 200 will automatically open. Conversely, when the monitoring device 300 detects that the heat load module 410 is in an inactive state, i.e., the module is not currently working and is not generating significant heat or current is flowing through it, the control valve 200 will automatically close. This configuration of the control valve 200 allows the system to control the flow rate of the heat exchange medium through each heat load module 410 according to the actual heat load requirements of that module. This configuration helps improve the efficiency of the entire cooling system, and heat exchange resources can be more rationally allocated to the modules that need them.

[0052] Optionally, the control valve 200 can be designed to adjust the opening ratio, rather than just being fully open or fully closed, to achieve flow control.

[0053] The cooling system also includes: a heat dissipation unit connected to the flow channel 100; the heat dissipation unit is connected to the outside; wherein, based on the connection between the heat dissipation unit and the flow channel 100, the heat exchange medium passes from the flow channel 100 through the heat dissipation unit; the heat dissipation unit is configured to exchange heat with the outside through the heat exchange medium flowing through the heat dissipation unit.

[0054] In the above implementation process, the heat dissipation unit is connected to the flow channel 100, and the heat exchange medium flows in the flow channel 100. The heat absorbed from the heat load module 410 is transferred to the heat dissipation unit, which then dissipates the heat from the heat exchange medium to the external environment, achieving thermal balance and stable operation of the entire system. The heat dissipation unit includes a radiator 500 and heat dissipation blades 510. The heat dissipation blades 510 are installed on one side of the radiator 500 and face towards the radiator 500. The heat dissipation blades 510 are configured to adjust their rotational speed based on thermal monitoring data.

[0055] In the above implementation process, the heat dissipation unit consists of a radiator 500 and heat dissipation blades 510 (typically referring to a fan), which work together to improve the heat dissipation efficiency of the heat exchange medium. The heat dissipation blades 510 are mounted on one side of the radiator 500, typically to effectively blow air towards or through the radiator 500 to enhance heat dissipation. The heat dissipation blades 510 are positioned facing the radiator 500 to ensure that airflow is optimized for the radiator 500, improving heat dissipation efficiency. When the temperature of the heat load module 410 rises, the rotation speed of the heat dissipation blades 510 increases to improve heat dissipation capacity; when the temperature decreases, the rotation speed decreases to save energy. Adjusting the rotation speed of the heat dissipation blades 510 also helps balance noise levels and heat dissipation performance to meet the requirements of use in different environments. The operation of the heat dissipation unit relies on an intelligent control system, which automatically adjusts based on real-time data, improving the convenience of operation and the reliability of the system.

[0056] Optionally, the heat dissipation unit may be equipped with a variable speed fan that adjusts the fan speed according to the temperature of the heat exchange medium or the number of heat load modules 410 called, in order to optimize heat dissipation efficiency.

[0057] In one embodiment of this application, it is assumed that the total number of heat load modules is M0, and M0 > 1. The number of modules called is represented by M, where high load is M > M1, medium load is M1 ≥ M ≥ M2, and low load is M < M2; the ambient temperature is assumed to be Temp, where high temperature is Temp > Temp1, normal temperature is Temp1 ≥ Temp ≥ Temp2, and low temperature is Temp < Temp2; the temperature of the called modules is represented by T, where high temperature is T > T1, medium temperature is T1 ≥ T ≥ T2, and low temperature is T < T2. Corresponding to different numbers of called heat load modules, the temperatures of the called heat load modules, and the ambient temperature, the fan speed is represented by N, with ranges of N0, N1, N2, ..., N27.

[0058] This application also provides a charging system, which includes a charging device and a cooling system; the cooling system is connected to the charging device; the cooling system is configured to dissipate heat from the charging device.

[0059] Please see Figure 3, Figure 3 This is a schematic diagram of a specific embodiment of the charging system provided in this application.

[0060] The thermal load module 410 is a charging module 411 used to charge the device to be charged. The control valve 200 is a solenoid valve 211 used to control whether the heat exchange medium (referring to the cooling medium) circuit is open. The monitoring device 300 is used to detect: ambient temperature, module operating status, and retrieve thermal monitoring data such as module temperature.

[0061] The fluid transport pump 110, fluid storage unit 120, radiator 500, and heat load device 400 are connected via flow channel 100. The heat load device 400 has multiple parallel charging modules 411, and each charging module 411 has a corresponding solenoid valve 211 at its heat exchanger inlet. When a charging module 411 is in the activated state, the corresponding solenoid valve 211 opens, and the heat exchange medium (cooling medium) circuit of that module is open. When a charging module 411 is in the standby / not activated state, the corresponding solenoid valve 211 closes, and the heat exchange medium circuit of that module is blocked. The flow channel 100 in the fluid transport unit is responsible for transporting the heat exchange medium (such as coolant) from the heat load device 400 to the radiator unit and back to the heat load device 400, forming a closed loop. The rotational speed of the fluid transport pump 110 varies with the number of solenoid valves 211 that are open; the more solenoid valves are open, the faster the rotational speed, and vice versa. The rotational speed of the heat dissipation blade 510 varies with the ambient temperature, the number of solenoid valves 211 that are open, and the temperature of the calling module. When the ambient temperature is high, the number of solenoid valves 211 that are open is greater, and the temperature of the calling module is higher, the rotational speed of the heat dissipation blade 510 is higher, and vice versa.

[0062] In the above implementation process, the cooling system is configured to dissipate heat from the charging device, effectively absorbing and removing the heat generated during charging. The efficient heat dissipation function of the charging system ensures that the device maintains a suitable temperature during charging, enhancing charging safety and improving system efficiency.
