Description

Technical fields: This invention relates to the field of computer peripherals technology, and in particular to a liquid cooling control method, system, computer-readable storage medium, and computer program for an external bracket-type electronic device. Background technology: With the continuous advancement of semiconductor technology, the performance of portable or compact electronic devices, represented by high-performance laptops and mobile workstations, is becoming increasingly powerful. As a result, the power consumption and heat generation of their core processing units (such as CPUs and GPUs) are also rising sharply. The limited space inside these devices poses a huge challenge to heat dissipation design.

[0001] Currently, there are several mainstream heat dissipation solutions on the market: The first type is the traditional air-cooled heat sink bracket, which enhances air convection by adding an external centrifugal fan. However, due to the low heat capacity of air, its heat dissipation efficiency improvement is limited. Under high load conditions, the centrifugal fan needs to rotate at high speed to achieve the heat dissipation target, resulting in unbearable noise. The second type is the external liquid cooling solution, which utilizes the high specific heat capacity of liquids and generally has a much higher heat dissipation efficiency than air cooling. However, most existing liquid cooling solutions of this type have problems such as complex installation process, need to modify the device itself, and poor portability. More importantly, its control strategy is usually relatively simple, mostly manual gear adjustment or on / off control based on a single temperature threshold, which cannot accurately match the dynamically changing heat dissipation needs of the device and is difficult to achieve an ideal balance between performance, power consumption, and noise. The third type is a hybrid heat dissipation system that combines air cooling and liquid cooling. However, existing solutions are often just a simple superposition of the two heat dissipation methods, lacking deep integration and coordinated control, resulting in an unreasonable system layout and failing to fundamentally solve the technical problem of intelligent adaptation to different application scenarios. Summary of the Invention: The main objective of this invention is to provide an external bracket-type electronic device liquid cooling system and control method, aiming to solve the technical problems of the prior art, such as simple heat sink control strategies, inability to coordinate and balance heat dissipation performance and noise, and insufficient intelligence.

[0002] To achieve the above objectives, the present invention provides a control method for an external bracket-type electronic device liquid cooling system, comprising: A temperature-flow dual closed-loop coordinated control strategy is adopted, which includes: obtaining the coolant inlet temperature and coolant outlet temperature of the liquid cooling circuit that is in fluid communication with the electronic equipment through a feedback control loop; Calculate the real-time temperature difference ΔT based on the coolant inlet temperature and coolant outlet temperature; Based on the deviation between the real-time temperature difference ΔT and the preset target temperature difference ΔTtarget, the operating power of the water pump in the liquid cooling circuit is adjusted through the feedback control loop; In addition, the surface temperature of the electronic device's housing is obtained through a feedforward control loop; The speed of at least one centrifugal fan is adjusted via a feedforward control loop based on the surface temperature of the housing.

Each set of heat dissipation units includes a centrifugal fan and a finned heat exchanger. The centrifugal fan is configured to draw in air from the bottom of the support body and blow the air towards the finned heat exchanger before discharging it from the side.

Compared with the prior art, the present invention has the following beneficial effects: 1. Achieving a balance between performance and user experience through collaborative control: This invention constructs a dual-loop collaborative control system that combines temperature difference feedback and surface temperature feedforward; the feedback loop precisely adjusts the water pump, which can efficiently transfer core heat and help ensure the release of equipment performance; the feedforward control loop quickly responds to changes in surface temperature, which can predictively adjust the centrifugal fan, thereby actively managing noise; the two work together to a certain extent to solve the technical problem of balancing performance and noise in traditional solutions.

[0017] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below through specific embodiments and related drawings.

Detailed implementation method: The technical solutions of the present invention will now be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention.

[0023] This invention provides an external bracket-type electronic device liquid cooling system and a corresponding control method.

[0024] In one specific embodiment, the system is physically manifested as an external support frame; its hardware configuration can be found in [link to relevant documentation]. Figures 1-3 The system includes a support body 1 made of high-strength aluminum alloy, two sets of heat dissipation units symmetrically arranged on the left and right sides of the support body 1, a liquid cooling center 3 integrated in the middle of the support body 1, a set of sensors, and a control module 10.

[0025] In a specific, non-limiting example, each heat dissipation unit includes a 92mm centrifugal fan 4 and a combined aluminum fin and copper microchannel heat exchanger 2 with a total heat dissipation area of ​​approximately 0.15 m². This symmetrical layout not only makes the structure more stable but also optimizes heat dissipation efficiency. The centrifugal fan 4 is designed to draw in cooler ambient air from the bottom of the bracket. After the air blows over the fins of the heat exchanger 2 and carries away the heat, it is exhausted from the side of the system. This airflow design, compared to traditional rearward or upward exhaust, effectively avoids hot air recirculation and direct airflow to the user, helping to reduce perceptible noise at the user's location.

[0026] The liquid cooling center 3 includes a 300mL storage tank 7, a 12V water pump 5 with a maximum flow rate of 2.5L / min, and an electric shut-off valve 11; the system is connected to the liquid cooling interface of the laptop computer via a quick-connect bidirectional water stop connector 6, enabling tool-free quick installation.

[0027] The control module 10 is the control core of the entire system, and its hardware core is a 32-bit ARM Cortex-M4 microcontroller (MCU). This module implements PD protocol (e.g., 20V / 5A) power supply and USB HID data communication through a USB-C interface, and also integrates a Bluetooth 5.0 module for wireless communication with mobile devices such as mobile phones.

[0028] The system's sensor suite forms the data foundation for intelligent control and includes: an NTC temperature sensor installed on the inlet and outlet pipes of the liquid cooling circuit to acquire the coolant inlet temperature (Tin) and outlet temperature (Tout); an infrared temperature sensor installed on the support body 1, facing the heat-generating core area of ​​the electronic device, to acquire the surface temperature (Tsurf) of the electronic device's casing in a non-contact manner; a Hall effect flow sensor 12 installed on the main pipe of the liquid cooling circuit; and a resistive leakage sensor 13 located at the lowest point of the bottom surface inside the support body 1.

[0029] The core of this embodiment lies in the collaborative intelligent control method executed by the control module 10; this method fully embodies the core concept of the present invention, including the collaborative operation of a feedback control loop and a feedforward control loop; specifically, the method includes: A temperature-flow dual closed-loop coordinated control strategy is adopted. The strategy includes the following steps: First, the control module 10 acquires the coolant inlet temperature (Tin) and coolant outlet temperature (Tout) of the liquid cooling circuit fluidly connected to the electronic equipment via an NTC temperature sensor. Next, the MCU calculates the real-time temperature difference (ΔT = Tout - Tin) based on these two temperature values. Then, based on the deviation between this real-time temperature difference (ΔT) and a preset target temperature difference (ΔTtarget), a feedback control loop adjusts the operating power of the water pump 5 in the liquid cooling circuit. This feedback loop aims to precisely control the core heat dissipation capacity of the system.

[0030] Simultaneously, the method also includes acquiring the housing surface temperature (Tsurf) of the electronic device using an infrared temperature sensor via a feedforward control loop. Finally, based on the acquired housing surface temperature (Tsurf), the speed of at least one centrifugal fan 4 is adjusted via a feedforward control loop. This feedforward loop is designed to proactively address thermal shocks and manage noise actively.

[0031] It is worth noting that the control module 10 regulates the power of the water pump 5 and the centrifugal fan 4 by outputting a pulse width modulation (PWM) signal with a frequency of 25kHz. Choosing 25kHz, a frequency higher than the upper limit of human hearing, effectively avoids electromagnetic noise that may be generated during speed adjustment, providing hardware-level assurance for the system's quiet operation.

[0032] In a preferred embodiment, the centrifugal fan adjustment strategy in the feedforward control loop is further refined. This strategy includes setting a first temperature threshold (e.g., 40°C) and a second temperature threshold (e.g., 50°C). When the measured Tsurf is below the first temperature threshold, it indicates a low equipment load. In this case, the speed of the centrifugal fan 4 is set to a lower first preset speed (e.g., 30% of the rated speed) to prioritize quiet operation. When Tsurf is not lower than the first temperature threshold but lower than the second temperature threshold, it indicates a moderate equipment load. In this case, the speed of the centrifugal fan 4 is increased accordingly based on the increment of Tsurf relative to the first temperature threshold. For example, a linear increase strategy can be used, such as Rfan = 30% + (Tsurf - 40) * 4%, to achieve a smooth transition and avoid sudden noise changes. When Tsurf is not lower than the second temperature threshold, it indicates a high or full load condition. In this case, the speed of the centrifugal fan 4 is set to the maximum speed (100%) to provide the strongest air-cooled auxiliary heat dissipation capability.

[0033] In another preferred embodiment, the feedback control loop employs an adaptive proportional-integral-derivative (PID) control algorithm. Its "adaptive" characteristic is reflected in the fact that the algorithm dynamically adjusts the proportional coefficient (kp) in the PID controller based on the real-time temperature difference (ΔT). Specifically, kp is positively correlated with the magnitude of ΔT. For example, this can be achieved using the formula kp = base_kp * (1 + ΔT * adaptive_factor). The technical advantage of this design is that when the equipment load increases sharply, causing ΔT to increase rapidly, the system can automatically increase the kp value, making the pump power response faster and stronger, thereby quickly suppressing the temperature rise; while when the load is stable or decreasing, the kp value is decreased, making the system adjustment smoother and avoiding overshoot and oscillation.

[0034] To meet diverse user needs, the method of this invention also supports multi-mode operation. Users can select modes via a Bluetooth-connected mobile app or a USB-connected PC software. These modes include: a silent mode, in which the preset target temperature difference (ΔTtarget) is set to a relatively high first target value (e.g., 7°C), meaning the system allows for a slightly larger temperature difference in exchange for lower energy consumption and noise; and a performance mode, in which the preset target temperature difference (ΔTtarget) is set to a relatively low second target value (e.g., 3°C), which is greater than the first target value. In performance mode, the system operates with extremely high sensitivity, ensuring that heat is dissipated as quickly as possible, thereby supporting the device's peak performance output for extended periods.

[0035] Furthermore, to improve product reliability under different environments, the method of this invention also incorporates a low-temperature protection operation strategy. This method includes: when the coolant inlet temperature (Tin) is detected by a temperature sensor to be below a preset low-temperature threshold (e.g., 5°C), the control module 10 controls the water pump 5 to operate in a preset intermittent mode (e.g., running for 2 seconds, then stopping for 8 seconds). This approach aims to maintain a weak flow of coolant with extremely low energy consumption, effectively preventing problems such as icing or reduced flowability in the pipes due to liquid stasis in cold environments.

[0036] This invention also provides a complete safety protection mechanism. The method includes: continuously monitoring the operating status of the liquid cooling circuit through the flow sensor 12 and / or the leakage sensor 13; triggering the safety protection mechanism when a preset abnormal state is detected. Specifically, when the control module 10 detects that the flow rate is consistently below 0.2 L / min for more than 3 seconds, or detects that the resistance value of the leakage sensor is below 100 kΩ, it will determine it as an abnormal state. At this time, the control module 10 will immediately trigger the safety protection mechanism, executing a series of linked operations, including: controlling the electric shut-off valve 11 to close, stopping the water pump 5, illuminating the red LED warning light, and sending alarm information to the user equipment through the communication interface.

[0037] The following are specific embodiments of the present invention in different application scenarios: Example 1: Esports event live streaming scenario In this scenario, a gaming laptop equipped with an Intel i9-14900HX processor and an NVIDIA RTX4090 graphics card was used for high-quality game streaming, with the CPU power consumption consistently at 140W. To ensure no frequency throttling and smooth streaming throughout the game, the user set the liquid cooling system to "performance mode" via PC software. At this time, the system's preset target temperature difference ΔTtarget was set to 3℃. During high-load gaming, the CPU and GPU generated enormous heat, causing the coolant outlet temperature Tout to rise rapidly, resulting in an increase in the real-time temperature difference ΔT. The adaptive PID controller detected this drastic change in ΔT and immediately increased the proportional coefficient kp, driving the water pump to operate at near full power to quickly dissipate core heat. Simultaneously, the laptop's bottom case temperature Tsurf rapidly exceeded 50℃, prompting the feedforward control loop to increase the centrifugal fan speed to 100% for powerful auxiliary cooling. Ultimately, the laptop's core temperature was stabilized within a safe range without any frequency reduction. Furthermore, thanks to the bottom-suction and side-exhaust design, the measured noise level in the audience area was below 35dB, far superior to the performance of traditional air-cooled radiators under these conditions.

[0038] Example 2: Library Reading Room Usage Scenarios In this scenario, users are using laptops for document processing and web browsing in the library, making them extremely sensitive to noise. The user sets the liquid cooling system to "silent mode" via a mobile app. At this time, the system's preset target temperature difference ΔTtarget is set to a relatively high 7°C. Under light load, the laptop generates little heat, and the real-time temperature difference ΔT remains below 7°C, with the water pump operating at extremely low power. Simultaneously, the bottom case temperature Tsurf remains stable below 40°C, and the centrifugal fan speed is locked at the lowest preset value of 30%. The entire system operates extremely quietly, with measured operating noise below 32dB(A), almost inaudible, perfectly blending into the quiet environment of the library. Even when occasional high-definition video playback temporarily increases the load, the system smoothly and slightly increases the power of the water pump and centrifugal fan, avoiding sudden changes in noise.

[0039] Example 3: AI Deep Learning Training Scenario In this scenario, a mobile workstation was used for prolonged GPU-intensive AI model training. Located in an office, its original air-cooling system generated up to 60dB of continuous noise during training, severely impacting the work environment. After connecting this liquid cooling system, the system automatically recognized the prolonged high load and operated stably. Thanks to the high efficiency of liquid cooling, most of the heat was dissipated through liquid circulation, and the centrifugal fan only needed to operate at low to medium speeds to maintain a stable overall temperature. Ultimately, the workstation's operating noise was successfully controlled below 40dB, significantly improving the engineer's working environment while ensuring the GPU could continuously operate at full load, thus improving training efficiency.

[0040] Example 4: Mobile Computing Scenario for Field Geological Exploration In this scenario, a ruggedized laptop is installed inside an exploration vehicle for real-time processing and modeling of geological data. The ambient temperature inside the vehicle can reach as high as 40°C, and air conditioning cannot be installed. This liquid cooling system, through its highly efficient heat dissipation capabilities, ensures that the laptop can still output high performance in high-temperature environments, avoiding the risk of crashing due to overheating associated with traditional air-cooled solutions. Its side exhaust design effectively prevents dust from being blown directly towards the operators or equipment air intakes. When the vehicle is parked at night and the ambient temperature drops below 5°C, the system's low-temperature protection mechanism is activated. The water pump operates in an intermittent mode, running for 2 seconds and stopping for 8 seconds, consuming extremely low power and effectively preventing the coolant from freezing in the pipes, ensuring that the equipment can start normally the next day.

[0041] Those skilled in the art will understand that the present invention also provides a computer-readable storage medium, such as the Flash memory inside the control module 10, which stores a computer program that, when executed by a processor, can implement the above-described method embodiments.

[0042] Similarly, the present invention also provides a computer program product comprising computer program instructions that, when executed by a processor, enable the implementation of the above-described method embodiments.

[0043] Finally, it should be noted that the embodiments of the present invention are not limited to laptops, but can also be widely applied to other portable or compact electronic devices that require enhanced external heat dissipation, such as mobile workstations, all-in-one computers, and high-performance mini-PCs.
