Description

Technical Field

[0001] This invention relates to the field of battery thermal management technology, specifically a power supply thermal management system. Background Technology

[0002] Power management also involves thermal management, especially how the dissipation of power-related functions affects thermal design and heat accumulation. In addition, even if components and systems continue to operate within specifications, as component parameters drift, the increase in temperature will cause performance changes and system failures. Heat will also shorten component life and thus shorten mean time between failures.

[0003] Power supply thermal management is mainly used for battery thermal management, controlling battery temperature to prevent changes in battery performance, thereby increasing battery efficiency. Current battery thermal control mainly uses air cooling. If the operating environment temperature cannot be effectively controlled within a reasonable range, the internal temperature of the power supply may become too high or too low, or the internal temperature distribution may be uneven. This not only greatly affects the performance and lifespan of the power supply, but also poses significant safety hazards. When the discharge capacity increases, air cooling cannot effectively manage the thermal of the power supply, leading to excessively high local temperatures. Summary of the Invention

[0004] The purpose of this invention is to provide a power thermal management system to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a power thermal management system, comprising a battery module, a control module, and a cooling module, wherein the control module is signal-connected to the battery module, and the cooling module is signal-connected to the control module.

[0006] The control module includes a thermal management system.

[0007] Preferably, the battery module includes a protective plate, a battery, and a fan, with the battery disposed inside the protective plate and the fan mounted on one side of the protective plate.

[0008] Preferably, the thermal management system includes a voltage meter, a power meter, a current meter, and a temperature meter, which are sequentially connected to the battery signal.

[0009] Preferably, the cooling module includes a condenser plate, an input pipe, a condenser, a compressor, a connecting pipe, a water tank, a water pump, and an output pipe. The condenser plate is located on top of the battery. The input pipe flange is connected to one end of the condenser plate, the condenser flange is connected to the other end of the input pipe, the compressor is located at one end of the condenser, the connecting pipe flange is connected to one end of the condenser, the water tank flange is connected to the other end of the connecting pipe, the water pump is located on top of the water tank, and the output pipe is located at one end of the water tank. The temperature of the battery is measured by a temperature measuring device in the thermal management system, thereby controlling the water pump to start. This allows coolant to enter the condenser from the water tank through the connecting pipe. The condenser cools the coolant through the compressor, and then the coolant is input into the condenser plate through the input pipe. The bottom of the condenser plate contacts the top of the battery, absorbing the heat generated by the battery and cooling the battery. After the temperature drops, the thermal management system stops the water pump, condenser, and compressor, saving energy.

[0010] Preferably, the number of fans is four. The fans are used to obtain sufficient airflow when the flow is obstructed, or when the battery temperature is not high, the thermal management system controls the fans to start individually or separately, thereby reducing power consumption, and uses blades that can reduce noise at the optimal operating speed.

[0011] Preferably, the temperature measuring device has a temperature measurement range of -25 degrees Celsius to 105 degrees Celsius, which can cover the operating environment of conventional batteries, thereby facilitating the thermal management system to perform temperature measurement, voltage control, and current control.

[0012] Preferably, the water pump is equipped with a valve inside, and the opening and closing of the valve is controlled by the thermal management system, thereby controlling the flow rate of coolant, which facilitates the adjustment of battery temperature and energy consumption.

[0013] Preferably, the protective plate is made of aluminum shell material, and the protective plate completely surrounds the battery. The aluminum material is used to strengthen the structural strength of the battery, ensuring that the battery is not easily deformed under the action of external force. At the same time, the aluminum material has good thermal conductivity, which can dissipate some of the heat generated by the battery, making it easier to cool the battery.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. This power supply thermal management system measures the battery temperature using a temperature measuring device within the system, and then uses a condenser plate, condenser, and water pump to cool the battery, thereby ensuring stable power supply heat and stable battery output power without voltage fluctuations.

[0016] 2. This power thermal management system ensures that the battery is not easily deformed under external forces by setting a protective plate on the outside of the battery. At the same time, the aluminum material has good thermal conductivity, which can dissipate some of the heat generated by the battery, making it easier to cool the battery.

[0017] 3. This power thermal management system can control individual or separate startup to reduce power consumption. It also uses blades that can reduce noise at the optimal operating speed. When the battery temperature is not high, it can save energy by cooling. When the battery is overheated, it can combine with the condenser plate to cool the battery quickly.

[0018] 4. This power thermal management system controls the opening and closing of valves. The valves are located inside the water pump, and the flow rate of the water pump is controlled by the valves, thereby controlling the flow rate of the coolant, which facilitates the adjustment of the battery temperature and the control of energy consumption.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figure 1-3 The present invention provides a technical solution: a power thermal management system, including a battery module, a control module and a cooling module, wherein the control module is signal-connected to the battery module and the cooling module is signal-connected to the control module.

[0025] The control module includes the thermal management system 4.

[0026] The battery module includes a protective plate 1, a battery 2, and fans 3. The battery 2 is located inside the protective plate 1, and the fans 3 are installed on one side of the protective plate 1. There are four fans 3. When the airflow is obstructed, the fans 3 are activated to obtain sufficient airflow. Alternatively, when the battery 2 temperature is not high, the thermal management system 4 controls the fans 3 to start individually or separately, thereby reducing power consumption. The fans 3 also use blades that can reduce noise at the optimal operating speed. The protective plate 1 is made of aluminum and completely surrounds the battery 2. The aluminum material is used to strengthen the structural strength of the battery 2, ensuring that the battery 2 is not easily deformed under external forces. At the same time, the aluminum material has good thermal conductivity, which can dissipate some of the heat generated by the battery 2, facilitating the cooling of the battery 2.

[0027] The thermal management system 4 includes a voltage meter, a charge meter, a current meter, and a temperature meter. These meters are sequentially connected to the battery 2. The temperature meter's measurement range is from -25 degrees Celsius to 105 degrees Celsius, encompassing the typical operating environment of the battery 2. This facilitates temperature measurement, voltage control, and current control by the thermal management system 4. The voltage meter is a 24-channel inspection unit. Its main function is to perform real-time online inspection of the voltage of each individual battery in the series-connected battery 2, and intelligently analyze the battery 2's operating status. Based on different upper and lower limits and average deviations set by the user, it automatically judges and outputs warnings, thereby enabling timely detection of faulty batteries, ensuring the safe operation of the power supply, and improving the system's reliability and automation. The current meter is a module that measures the internal resistance of the battery 2 based on individual cells using a small DC discharge method. It can measure the individual cell current, internal resistance, and terminal temperature of the individual battery 2 to achieve balanced charging and discharging functions for the battery 2.

[0028] The cooling module includes a condenser plate 5, an input pipe 6, a condenser 7, a compressor 8, a connecting pipe 9, a water tank 10, a water pump 11, and an output pipe 12. The condenser plate 5 is located on top of the battery 2. The input pipe 6 is flanged and connected to one end of the condenser plate 5. The condenser 7 is flanged and connected to the other end of the input pipe 6. The compressor 8 is located at one end of the condenser 7. The connecting pipe 9 is flanged and connected to one end of the condenser 7. The water tank 10 is flanged and connected to the other end of the connecting pipe 9. The water pump 11 is located on top of the water tank 10. The output pipe 12 is located at one end of the water tank 10. The temperature of the battery 2 is measured by a temperature measuring device in the thermal management system 4, which controls the start of the water pump 11. The coolant flows from the water tank 10 into the condenser 7 through the connecting pipe 9. The condenser 7 cools the coolant through the compressor 8, and then the coolant is fed into the condenser plate 5 through the input pipe 6. The bottom of the condenser plate 5 contacts the top of the battery 2, absorbing the heat generated by the battery 2 and cooling the battery 2. After the temperature drops, the thermal management system 4 stops the water pump 11, the condenser 7, and the compressor 8 to save energy. The water pump 11 has a valve inside, and the thermal management system 4 controls the opening and closing of the valve to control the flow of coolant, thereby facilitating the adjustment of the battery 2's temperature and controlling energy consumption.

[0029] When in use, the temperature of battery 2 is measured by the temperature measuring device in the thermal management system 4. If the temperature is too high, the thermal management system 4 controls the water pump 11 to start, so that the coolant enters the condenser 7 from the water tank 10 through the connecting pipe 9. The condenser 7 cools the coolant through the compressor 8, and then the coolant is introduced into the condenser plate 5 through the input pipe 6. The bottom of the condenser plate 5 contacts the top of battery 2, and the heat generated by battery 2 is absorbed by the condenser plate 5 to cool battery 2. When the temperature is normal, the thermal management system 4 controls the fan 3 to start to obtain sufficient airflow, or if the temperature of battery 2 is not high, the thermal management system 4 controls the fan 3 to start individually or separately to ventilate and cool battery 2. The voltage measuring device, the power measuring device, and the current measuring device measure the usage status of battery 2 during use, and display the power status of battery 2 on the external display screen, so that the operator can understand the status of battery 2 in real time.
