Abstract
Description
Technical Field
[0001] This invention relates to the field of thermoelectric conversion, and more particularly to a waste heat recovery system and method for laptop computers based on the thermoelectric conversion effect. Background Technology
[0002] During high-load operation of laptops, core hardware components such as the central processing unit (CPU), graphics processing unit (GPU), and power management module continuously release a large amount of waste heat, the heat density of which increases exponentially with performance demands. Traditional cooling architectures use a physical combination of metal heat pipes, aluminum heat sinks, and centrifugal fans to simply expel heat from the chassis through unidirectional conduction and forced convection. This linear cooling mode only focuses on alleviating the pressure of instantaneous temperature rise, but ignores the energy conversion potential contained in waste heat. Under prolonged high-load scenarios, the unidirectional dissipation of heat not only accelerates the efficiency decline caused by the aging of the cooling system, but also creates a continuous energy loss loop inside the device—electrical energy is converted into computing power by the chip, and ultimately dissipates into the environment in the form of disordered heat energy. This extensive "generation-emission" thermal management logic neither attempts to build a reverse coupling link between heat energy and electrical energy, nor does it convert local high temperatures into added value that can serve the system itself. It may even form hot spots on the surface of the chassis, affecting the user experience and exposing the limitations of traditional solutions in terms of energy cycle concepts and sustainable design dimensions. Regarding the above situation, the problems are as follows:
[0003] 1. Existing cooling methods for laptops have limited heat dissipation efficiency, resulting in ineffective utilization of heat energy, exacerbating greenhouse gas emissions and thermal pollution, further increasing the environmental burden and wasting resources;
[0004] 2. If heat energy recovery is implemented, the additional hardware such as the TEG (thermoelectric conversion module) array and energy storage module used will take up internal space in the laptop, which may reduce battery capacity or sacrifice a thin and light design.
[0005] 3. Due to its size, laptops generate relatively little electrical energy from internal temperature differences, requiring intelligent charging and discharging management strategies to make effective use of it. Summary of the Invention

[0073] During high-load operation of laptops, core hardware components such as the central processing unit (CPU), graphics processing unit (GPU), and power management module continuously release a large amount of waste heat, the heat density of which increases exponentially with performance demands. Traditional cooling architectures use a physical combination of metal heat pipes, aluminum heat sinks, and centrifugal fans to simply expel heat from the chassis through unidirectional conduction and forced convection.

It may even form hot spots on the surface of the chassis, affecting the user experience and exposing the limitations of traditional solutions in terms of energy cycle concepts and sustainable design dimensions. Regarding the above situation, the problems are as follows:
[0074] 1. Existing cooling methods for laptops have limited heat dissipation efficiency, resulting in ineffective utilization of heat energy, exacerbating greenhouse gas emissions and thermal pollution, further increasing the environmental burden and wasting resources;
[0075] 2. If heat energy recovery is implemented, the additional hardware such as the TEG array and energy storage module will take up internal space in the laptop, which may reduce battery capacity or sacrifice a thin and light design.
[0076] 3. Due to its size, laptops generate relatively little electrical energy from internal temperature differences, requiring intelligent charging and discharging management strategies to make effective use of it.
[0077] To address the problems mentioned above, this invention provides a waste heat recovery system and method for laptop computers based on thermoelectric conversion effects, thereby solving the aforementioned problems.
[0078] A waste heat recovery system for laptop computers based on thermoelectric conversion effect, such as Figure 1 As shown, the feature is that it includes:
[0079] The intelligent detection module 101 is used to detect the temperature inside the laptop through multiple temperature sensors located in the high-heat area inside the laptop and feed it back to the power management chip;
[0080] In some embodiments, this module distributes miniature digital temperature sensors in high-heat-sensitive areas of the laptop, such as the CPU core packaging layer, GPU memory power supply circuit, and motherboard inductor array, to achieve synchronous acquisition and transmission of temperature data from multiple nodes. It uses a built-in noise suppression algorithm to filter the raw signal in real time and feeds back the calibrated and accurate temperature field information to the power management chip, thereby achieving a refined improvement in energy efficiency ratio while ensuring the thermal safety threshold of core components.
[0081] The thermal management module 102 is used to dynamically adjust the system working area based on temperature sensor data using the power management chip, and to issue working instructions by selecting the area with the largest current temperature difference.
[0082] In some embodiments, this module analyzes the synchronous data stream of multiple temperature sensors in real time through a power management chip, calculates the instantaneous thermal gradient difference of each high-heat-generating unit, such as the CPU core cluster, GPU rendering engine, memory controller, etc., based on a dynamic temperature difference algorithm, and when it detects that the temperature difference value (ΔT = hot end temperature - cold end temperature) of a certain area exceeds a preset threshold, it is marked as the thermal management focus area, and the heat generation area is selected according to the size of the temperature difference.
[0083] The waste heat recovery module 103 is used to increase the temperature difference between the area and the cold end by using a thermally conductive silicone layer and micro heat dissipation fins, and to determine the target power generation unit in the area according to the working instruction, and to use the target power generation unit to convert the heat energy of the laptop computer during operation into electrical energy.
[0084] In some embodiments, this module establishes a low thermal resistance heat transfer path by tightly attaching a high thermal conductivity silicone layer to the surface of the high-heat-generating unit. Combined with microfabrication technology, an array of copper-magnesium alloy heat dissipation fins are integrated at the hot end of the thermoelectric module to forcibly expand the steady-state temperature difference gradient between the module and the cold end heat dissipation module. When the thermal management center determines that a certain area has reached the maximum effective temperature difference (ΔT_max), it activates the thin-film thermoelectric unit at the corresponding coordinate and uses the Seebeck effect to convert the directional heat flow into pulsating DC, which is then fed into the energy storage bus after multi-stage filtering and voltage regulation.
[0085] The current stabilization module 104 is used to convert the unstable low-voltage DC power output by the target power generation unit into stable electrical energy using a rectifier circuit and a DC-DC boost chip;
[0086] In some embodiments, this module performs polarity correction and initial smoothing of the bidirectional pulsating current output by the thermoelectric unit through a full-bridge rectifier circuit, and then connects to a wide input range DC-DC boost chip. The fluctuating low-voltage DC is boosted to a stable 5V output through the built-in synchronous rectification architecture. An adaptive algorithm is embedded in the boost topology to track the maximum power point in real time, and a filter network is used to eliminate switching noise. At the same time, reverse cutoff and overvoltage protection modules are integrated, and finally the purified electrical energy is injected into the energy storage device according to priority.
[0087] The intelligent energy storage control module 105 is used to use the stable electrical energy stored by the energy storage device, display the energy recovery status on the laptop, and automatically determine the usage mode of the recovered electrical energy according to user needs.
[0088] In some embodiments, this module uses a composite energy storage module, such as a lithium polymer battery and a supercapacitor connected in parallel, to receive stabilized electrical energy. It has a built-in bidirectional DC-DC controller to achieve dynamic switching of charging and discharging paths. Simultaneously, a visual interactive interface is built at the operating system layer to display the dynamic recovery power curve, energy storage capacity percentage, and cumulative energy saving time statistics in real time. The underlying strategy engine intelligently schedules the priority of recovered electrical energy use based on the user's preset mode and real-time load requirements.
[0089] The analysis and reminder module 106 is used to perform user behavior analysis based on power generation status, analyze the status of the laptop components based on temperature detection results, perform intelligent configuration of the power generation unit based on the behavior analysis results, and issue component status reminders based on the component status analysis results.
[0090] In some embodiments, this module tracks user usage patterns in real time through a thermoelectric conversion efficiency matrix and builds a behavioral feature library. It simultaneously integrates multi-dimensional temperature sensing data streams, such as chip temperature, PCB board temperature rise rate, and heat dissipation module gradient temperature difference, to perform coupled analysis of hardware aging coefficient and instantaneous thermal stress. When it is identified that the user is continuously in a high power generation demand scenario, the activation topology of the thermoelectric unit array is dynamically reconstructed, and the module with the optimal Seebeck coefficient is prioritized to the heat flux density peak area. When the temperature is abnormal, the status of the laptop components is analyzed and an alert is issued.
[0091] The working principle of the above technical solution is as follows: Multiple temperature sensors installed in the high-heat area inside the laptop detect the internal temperature of the laptop and feed it back to the power management chip. Based on the temperature sensor data, the system's working area is dynamically adjusted. The area with the largest current temperature difference is selected and a working command is issued to increase the temperature difference between this area and the cold end. The target power generation unit converts the heat energy of the laptop during operation into electrical energy. The unstable low-voltage DC power output is converted into stable electrical energy using a rectifier circuit and a DC-DC boost chip. Stable electrical energy is stored using an energy storage device. The energy recovery status is displayed on the laptop, and the method of using the recovered energy is automatically determined according to user needs. User behavior analysis is performed based on the power generation status. The status of the laptop components is analyzed based on the temperature detection results. The power generation unit is intelligently configured based on the behavior analysis results. The component status reminder is issued based on the component status analysis results.
[0092] The beneficial effects of the above technical solution are as follows: Multiple temperature sensors detect the internal temperature of the laptop and feed it back to the power management chip, reducing the number of temperature sensors while improving detection efficiency; dynamically adjusting the system's working area based on temperature sensor data enhances system intelligence and reduces heat waste; increasing the temperature difference between the heat-generating and cold-generating areas, and using a target power generation unit to convert the laptop's heat energy into electrical energy, effectively improves heating efficiency; converting unstable low-voltage DC output into stable electrical energy improves system safety; using an energy storage device to store stable electrical energy, displaying the energy recovery status on the laptop, and automatically determining the usage method of the recovered energy based on user needs enhances system intelligence; performing user behavior analysis and laptop component status analysis, intelligently configuring the power generation unit, and issuing component status reminders based on component status analysis results improves system usability and security, making the system more intelligent.

[0095] In some embodiments, this embodiment locates high-temperature areas using a thermal imager or existing heat dissipation design documents, and identifies key heat-generating components such as CPU, GPU, power module, SSD, and battery. Combined with the device structure, space is reserved for sensor installation to avoid interfering with the original heat dissipation system, such as fans and heat pipes.

Based on the preset temperature control strategy and dynamic threshold analysis, it accurately locates the local overheating area and updates it to the system temperature control center simultaneously.
[0099] The beneficial effects of the above technical solution are as follows: Using a temperature detection device to detect the heat generation of multiple components during laptop operation, identifying the heat-generating components and high-temperature locations of the laptop, and determining the location of temperature sensors based on these high-temperature locations, improves detection efficiency. Using multiple temperature sensors to detect the internal temperature of the laptop during operation generates multiple temperature detection signals from different locations, which are then fed back to the power management chip, improving data accuracy and real-time performance. The power management chip analyzes the temperature detection signals to determine the internal temperature distribution of the laptop during operation, facilitating targeted selection of power generation areas and improving system efficiency.
[0100] In one embodiment, the thermal management module includes:

[0104] The judgment submodule is used to determine the high heat generation area with the largest heat output inside the laptop in real time based on the temperature difference, and to determine whether the power generation efficiency of the high heat generation area is greater than the current energy consumption of the entire waste heat recovery system. If so, the high heat generation area is determined as the system working area and a power generation command is issued.
[0105] In some embodiments, this embodiment uses a thermal gradient tracking algorithm to analyze multi-node temperature difference data streams in real time, dynamically lock the peak region of instantaneous heat flux density, such as the CPU core or GPU memory power supply area under overclocking conditions, and evaluate the theoretical power generation of this region based on the Seebeck coefficient matrix and thermoelectric conversion efficiency model; at the same time, it calculates the energy consumption of the waste heat recovery system itself, including boost chip loss, heat dissipation boost power consumption and standby power consumption of the control unit. If the net energy gain threshold is exceeded, the region is marked as an effective working area through the priority arbitration engine, and adaptive voltage regulation is performed to maximize output, while the thermoelectric units in the low ΔT region are turned off to reduce losses;
[0106] The instruction generation submodule is used to obtain multiple micro thermoelectric power generation units existing in the determined system working area, identify the multiple micro thermoelectric power generation units as target power generation units, and issue corresponding dynamic power generation instructions.

If so, it designates the high-heat-generating area as the system's working area and issues a power generation command. The system only starts working when the power generation efficiency exceeds the system's energy consumption, reducing resource waste and component wear; it acquires multiple micro-thermal power generation units within the identified system working area, designates these units as target power generation units, and issues corresponding dynamic power generation commands, improving the system's intelligence.
[0108] In one embodiment, the waste heat recovery module includes:

[0110] In some embodiments, this embodiment establishes a low thermal resistance heat transfer channel by tightly attaching a high thermal conductivity medium layer to the surface of the high heat generation element, efficiently transferring the chip waste heat to the hot end of the thermoelectric unit array. At the same time, a micro heat dissipation structure is deployed at the cold end to enhance the environmental heat exchange capacity. The temperature difference gradient between the hot and cold ends is maximized through the synergistic effect of forced convection and radiation.

The power management chip continuously monitors the internal resistance change, output current ripple, and cold-end heat dissipation status of the power generation unit and dynamically executes control mode switching. When the input voltage is stable and the load demand is constant, it switches to constant voltage mode to maintain the bus voltage. If it detects that the input source fluctuates violently or the energy storage unit is close to full capacity, it switches to constant current mode to limit the peak current.

[0127] Energy storage submodule, used to recover electrical energy by connecting batteries and energy storage capacitors in parallel;
[0128] The power management submodule is used to set up multi-source charging and discharging through the power management chip. When the recovered power is greater than the current load demand of the equipment that needs to be powered, it is first stored in the energy storage device. When it is insufficient, it is first used to supply power to the equipment that needs to be powered.
[0129] In some embodiments, a multi-source energy routing hub is constructed through a power management chip to monitor the input power of waste heat recovery energy, main battery and external adapter and system load demand in real time. When the instantaneous power of the recovered energy exceeds the total load demand, the surplus energy is injected into the supercapacitor-lithium battery hybrid energy storage bus through a bidirectional DC-DC controller, and a trickle optimization algorithm is enabled to extend the life of the energy storage unit. If the recovered power is insufficient to support the current load, it seamlessly switches to the main battery or external power supply to make up the gap. At the same time, the power supply path is intelligently allocated based on the load type, and reverse cut-off and overcharge protection circuits are integrated in the charging and discharging link.
[0130] The visualization submodule is used to update the energy storage device's power level in real time on the laptop's display page via a system plugin;
[0131] In some embodiments, a dynamic energy information prompt module is built in the right side of the taskbar or the floating window on the desktop through a lightweight plug-in architecture that is deeply integrated into the operating system. By polling the energy storage bus charge data of the power management chip in real time, a dynamic charge and discharge rate curve is drawn using a rendering engine. The click interaction layer is embedded synchronously, and users can bring up the secondary panel to view the historical recovered energy distribution heat map, instantaneous power generation and energy saving contribution statistics. When a sudden change in energy storage capacity is detected (such as instantaneous high current charge and discharge), a smooth animation transition and abnormal status flashing prompt are triggered.
[0132] The automatic control submodule is used to dynamically adjust the laptop components that need to use recycled energy based on the user's usage behavior of the laptop.
[0133] The beneficial effects of the above technical solution are as follows: using batteries and energy storage capacitors in parallel for energy recovery improves energy recovery efficiency; the power management chip enables multi-source charging and discharging settings, prioritizing the storage of energy when the recovered energy exceeds the load demand of the current power-requiring equipment, and prioritizing power supply to the equipment when it is insufficient, thus improving system usability and lifespan; the energy storage device's power level is updated in real time on the laptop's display page via a system plugin; and the laptop components that require the use of recovered energy are dynamically adjusted based on the user's usage behavior, allowing for real-time interaction with the user and enhancing the user experience.

[0136] Based on the power generation curve, user scenarios are classified. Based on the amount of power generation, the scenarios are divided into standby mode, low load mode, and high load mode. User behavior profiles are constructed based on local power generation data. Based on the user behavior profiles, lightweight Markov chains are used to predict possible usage scenarios in the next stage.
[0137] In some embodiments, the standby mode, low load mode, and high load mode are respectively: Standby mode: near zero power generation, temperature maintained within +5°C; Low load mode: low power generation (<2W), medium-low frequency temperature fluctuation (40-60°C); High load mode: high power generation demand (>8W), GPU / CPU temperature surges synchronously (>75°C); Local power generation data includes charging frequency, duration, power generation efficiency, etc.; A Markov chain is a set of discrete random variables with Markov properties, possessing irreducibility, recurrence, periodicity, and ergodicity;
[0138] Based on the predicted usage scenario, high-temperature areas are matched, and the power generation units within the high-temperature areas are dynamically switched to high-priority power generation units. The power supply mode is automatically matched according to the load of the user's usage scenario.
[0139] In some embodiments, the automatic load matching power supply mode based on the user's usage scenario is to automatically adjust the power generation unit and efficiency based on the user's behavior; for example, when the user enters game mode, the entire TEG array is activated and the efficiency of the boost chip is improved, sacrificing quietness for power generation.
[0140] Obtain the temperature change curve for each high-heat area, and perform data analysis on the temperature change curve;
[0141] Based on the data analysis results, the health of the components in each high-heat area is assessed. The difference between the historical and current temperatures under the same usage load is compared. If the difference exceeds a preset threshold, the component in that area is determined to have poor health. A component health reminder is then sent to the corresponding component through the laptop display port.
[0142] In some embodiments, this embodiment mainly uses the following methods: heat dissipation efficiency calculation: comparing the historical and current temperature differences under the same load; battery aging detection: combining the charging efficiency (charging time / capacity growth) detection of the battery by the power generation module to determine the health of the components;
[0143] Based on the data analysis results, anomaly analysis is performed on the real-time temperature of the high-heat area. When the real-time temperature shows a sustained high temperature or a temperature jump, the corresponding high-heat area is identified as an abnormal area. The abnormal area component is obtained, and a component abnormality alert is issued through the laptop display port.
[0144] Based on the component health assessment results and the anomaly analysis results, behavior optimization suggestions are generated.
[0145] In some embodiments, the component status alert design incorporates a real-time notification mechanism. When an anomaly is detected, the system notifies the user via a notification or indicator light and provides suggested actions.
[0146] The beneficial effects of the above technical solution are as follows: It acquires the operating status of the power generation unit, records the power generation curve, classifies user scenarios based on the power generation curve, constructs user behavior profiles based on local power generation data, predicts possible usage scenarios in the next stage, matches high-temperature areas according to predicted usage scenarios, dynamically switches power generation units within high-temperature areas to high-priority power generation units, improves system response speed and power generation efficiency through priority adjustment, and enhances practicality. It automatically matches the power supply mode according to the load of the user's usage scenario, acquires the temperature change curve of the high-heat area, performs data analysis, assesses the component health of components in the high-heat area based on the data analysis results, sends component health reminders to corresponding components through the laptop display port, performs anomaly analysis on the real-time temperature of the high-heat area based on the data analysis results, identifies abnormal components, sends component anomaly reminders through the laptop display port, improving the system's safety factor, and generates behavior optimization suggestions based on the component health assessment results and anomaly analysis results, improving the system's intelligence and practicality.
[0147] In one embodiment, the system further includes an extension module for user-defined system functions and for performance verification of the system based on user requirements.
[0148] Obtain the adjustable system parameter types and determine the adjustment range of the safety parameters for each system parameter type;
[0149] In some embodiments, the system configurable parameter space, including voltage regulation slope, temperature control threshold, fan curve base point, etc., is traversed through the hardware abstraction layer. Combined with calibration values, thermodynamic simulation boundaries and measured aging coefficients, a multi-dimensional parameter safety domain model is established to dynamically define the legal adjustment range of each parameter in the time domain, spatial domain and operating conditions.
[0150] A system function customization page is generated based on the adjustable system parameter type and the safety parameter adjustment range. The system function customization page has multiple adjustable system parameters and is equipped with on / off and adjustment range options.
[0151] In some embodiments, the adjustable parameter metadata provided by the hardware abstraction layer is parsed by the dynamic rendering engine to generate a tree-structured hierarchical visual configuration interface. The top level is divided by functional domains, such as power consumption strategy, temperature control logic, and recycling intensity. The secondary menu displays parameter items in a card layout, such as voltage offset, fan start-up temperature, and thermoelectric unit activation threshold. Each parameter item is embedded with a dynamic range slider and a mode switch for automatic / manual operation. User configuration schemes can be saved as multiple preset modes.
[0152] Create a custom page that allows users to create multiple configuration files, each of which stores a different combination of system parameters;
[0153] Based on the system parameters adjusted by the user, predict the system behavior after the parameter adjustment, display the changing trend of key indicators, automatically identify contradictory parameter adjustments, and prompt the user to optimize the logic;
[0154] In some embodiments, when the user adjusts system parameters, such as fan speed offset, this embodiment dynamically calculates the quantitative relationship between power consumption, temperature, and noise, and generates visual feedback such as three-dimensional heat map, energy efficiency curve, and noise spectrum. When conflicting logic is detected, such as the parallel selection of "maximize performance" and "force silent mode", the conflicting items are automatically highlighted in red and optimization suggestions are pushed. At the same time, multiple feasible solutions are pre-simulated using the gradient descent method, and the core indicators under different configurations, such as the predicted trends of battery life change rate, peak temperature, and regenerative power, are displayed in a dynamic comparison view.
[0155] When a user confirms the parameter adjustment, the adjusted parameter is set as the confirmed value of the target parameter, and the user-defined system function is applied.
[0156] After applying the user-defined system function, the old and new configurations are applied alternately within a safe range to obtain real-time data of the system, record key data differences, and use the built-in algorithm to calculate the performance improvement range.
[0157] In some embodiments, this embodiment applies new and old configurations alternately within a safe range, such as running each for 15 minutes, records key data differences, and performs statistical significance analysis: a local t-test algorithm is used to determine whether the performance improvement exceeds the error range, and the performance improvement range is determined based on the error range;
[0158] The performance improvement range is compared with user needs to determine whether the user needs are met. If the user needs are not met, system parameters that can be optimized are identified, the parameters are optimized, and a performance optimization reminder is sent to the user through the custom page.
[0159] In some embodiments, this embodiment tracks the deviation between user-preset performance optimization goals, such as battery life extension rate, and actual system indicators in real time. When a key indicator is detected to have failed to reach the expected threshold, parameter space traversal analysis is automatically initiated to filter out adjustable variables strongly correlated with the target, such as thermoelectric unit activation density. Combined with historical parameter tuning data and hardware health status assessment, a progressive optimization scheme is generated. A dynamic pop-up prompt is triggered on a custom page to display the adjustable range of the current bottleneck parameter, the expected gain curve, and the potential risk level. A "one-click trial run" function is embedded to allow users to verify the adjustment effect in a simulation environment, while retaining the manual fine-tuning entry.
