[0026] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0027] In order to solve the problems mentioned in the background technology, according to one aspect of the embodiments of the present application, an embodiment of a graphics card heat dissipation method is provided.

[0028] like Figure 1 As shown, the above graphics card heat dissipation method can be applied to Figure 1 In the hardware environment shown, the system architecture 100 of the hardware environment includes a terminal device 101 and a server 103. The server 103 is connected to the terminal 101 via a network and can be used to provide services to the terminal or a client installed on the terminal. A database 105 can be set on the server or independently of the server to provide data storage services for the server 103. The network can include various connection types, such as wired or wireless communication links or fiber optic cables.

[0029] It should be noted that the graphics card cooling method provided in the embodiment of the present application is generally performed by a server and / or terminal device, and accordingly, the graphics card cooling device is generally provided in the server / terminal device. Figure 1 The number of terminal devices, networks and servers in the embodiment is merely illustrative. Any number of terminal devices, networks and servers may be provided as required.

[0030] Take the example of the graphics card cooling method based on air conditioning being executed by the server. Figure 2 As shown, the graphics card heat dissipation method is applied to a heat dissipation system, the heat dissipation system includes a graphics card and an air conditioner, a connecting channel is provided between the graphics card and the air conditioner, and a heat dissipation medium is provided in the connecting channel. The method includes the following steps:

[0031] Step S202: dissipate heat from the graphics card using the heat dissipation medium in the connection channel.

[0032] In this embodiment, the connection channel is a physical and data dual-dimensional interactive bridge between the air conditioner and the graphics card, which can transmit the operating temperature data of the graphics card in real time, realize the efficient coupling of the graphics card heat and the air conditioner cooling capacity, and thus realize heat exchange.

[0033] The physical layer of the connection channel exports the heat of the graphics card to the heat exchange end of the air conditioner; the data layer establishes a real-time communication link between the graphics card and the air conditioner controller.

[0034] Specifically, when the graphics card needs to be cooled, the heat dissipation medium in the connection channel can be used to dissipate heat for the graphics card, thereby ensuring that the graphics card quickly returns to normal temperature and providing users with a better user experience.

[0035] Step S204: When it is detected that the heat dissipation medium does not meet the heat dissipation requirement of the graphics card, the air conditioner is used to dissipate heat for the graphics card.

[0036] In some embodiments, the cooling effect of the heat dissipation medium is monitored in real time. If the heat dissipation medium is found to be unable to effectively meet the cooling needs of the graphics card, i.e., the graphics card temperature is still too high or is showing a trend of further increase, the air conditioner is activated to provide additional cooling for the graphics card. The air conditioner can enhance the cooling capacity of the graphics card by adjusting cooling parameters, such as lowering the outlet temperature and increasing the air volume, to ensure that the graphics card remains within the appropriate temperature range under various operating conditions.

[0037] It is understandable that traditional cooling methods usually directly control the operating status of the cooling equipment based on the temperature of the graphics card, such as fan speed and water pump power. Air cooling relies on fan rotation to accelerate air flow to remove heat, water cooling dissipates heat through liquid circulation, and passive cooling relies on the natural heat dissipation of the heat sink. As a result, these methods are difficult to quickly balance the temperature when the graphics card load changes and heat is generated rapidly. In addition, in traditional air cooling, the fan often maintains a certain speed and continues to run, consuming electricity even when the graphics card is in a low-load, low-heat state; the same is true for the water pump of the water cooling system. However, the present application uses phase change materials to absorb heat when the graphics card is under low load and generates less heat. At this time, there is no need to start energy-consuming equipment such as the compressor, effectively avoiding the energy consumption of traditional cooling methods when it is not necessary, reducing overall energy consumption and achieving energy saving.

[0038] In this embodiment, the heat dissipation medium absorbs the graphics card's heat. This allows for the rapid generation of heat due to changes in graphics card load, effectively smoothing temperature fluctuations by leveraging its temperature-remaining constant during phase transitions. During sudden high-load conditions, the heat dissipation medium absorbs significant amounts of heat and melts, preventing a sharp rise in graphics card temperature. This maintains a stable operating temperature and mitigates the impact of excessive temperature fluctuations on the performance and lifespan of the graphics card.

[0039] Through steps S202 to S204, the present application is different from traditional air cooling, water cooling and passive cooling methods. Instead, it adopts a graphics card cooling method of heat dissipation medium + air conditioning. When the graphics card temperature is not high and the heat dissipation demand is low, the graphics card can be cooled by the heat dissipation medium. When the heat dissipation medium does not meet the heat dissipation demand of the graphics card, the air conditioner is added to cool the graphics card. The temperature control advantages of air conditioning technology can be used to improve the heat dissipation effect of the graphics card and the flexibility of heat dissipation control.

[0040] In an optional embodiment, the heat dissipation medium includes a phase change material.

[0041] In some embodiments, the heat dissipation medium is a material capable of transferring heat. Phase change material (PCM) can be selected as the material. Preferably, a waxy PCM can be selected as the medium for transferring heat within the connecting channel. This heat dissipation medium absorbs heat and melts in its solid state, solidifies upon cooling, and maintains a constant temperature throughout the material's phase change. Therefore, it can act as a refrigerant to absorb the heat generated by the graphics card during operation, dissipating heat from the graphics card, smoothing temperature fluctuations, and preventing sudden temperature increases. Furthermore, when the graphics card's temperature just exceeds a preset threshold, passive heat dissipation from the PCM is prioritized, eliminating the need for power consumption. The compressor is activated only when the PCM's heat dissipation capacity is insufficient, reducing inefficient energy consumption.

[0042] In an optional embodiment, when it is detected that the heat dissipation medium does not meet the heat dissipation requirement of the graphics card, using the air conditioner to dissipate heat for the graphics card specifically includes:

[0043] Obtaining the actual temperature of the graphics card;

[0044] When the actual temperature is greater than a preset temperature threshold, the air conditioner is turned on to perform heat exchange with the phase change material to dissipate heat from the graphics card.

[0045] In some embodiments, a preset temperature threshold provides a clear boundary for the graphics card's safe operating temperature range. This threshold can be set based on the graphics card's operating temperature tolerance or optimal operating temperature, fully accounting for hardware differences between different graphics cards and improving the adaptability and reliability of the cooling device for different graphics card cooling scenarios. When the actual temperature exceeds this threshold, it indicates that the current wax phase change material can no longer meet the cooling requirements, and the air conditioner is activated to intervene.

[0046] In some optional examples, users can dynamically adjust the preset temperature threshold according to the usage scenario. For example, the preset temperature threshold can be adjusted to 75°C in a gaming scenario and to 55°C in an office scenario, which can be used to balance heat dissipation efficiency and energy consumption.

[0047] In this embodiment, the heat dissipation method is dynamically adjusted according to the actual heating situation of the graphics card, that is, the heat dissipation medium and the air conditioning heat dissipation, thereby avoiding blind heat dissipation or insufficient heat dissipation, and improving the targetedness and effectiveness of heat dissipation; the threshold-based control strategy can respond to the heat dissipation needs of the graphics card in a timely manner, ensuring that the graphics card will not be in a high temperature state for a long time, effectively protecting the graphics card hardware and extending its service life.

[0048] In an optional embodiment, before turning on the air conditioner to perform heat exchange with the phase change material, the method further includes:

[0049] When the actual temperature is greater than the preset temperature threshold, obtaining a phase change value of the phase change material;

[0050] When the phase change value reaches a preset phase change threshold, the step of turning on the air conditioner to perform heat exchange with the phase change material is performed.

[0051] In this embodiment, the phase change value of the phase change material can reflect how much heat the phase change material absorbs at this time, thereby determining whether the heat absorption limit of the phase change material has been reached or whether the phase change material can no longer meet the heat dissipation requirements.

[0052] In this embodiment, the preset phase change threshold indicates the maximum heat absorption limit of the phase change material or whether the phase change material can no longer meet heat dissipation requirements. The phase change threshold can be quantified using a viscometer and set by the user. If the user does not set a threshold, the compressor is activated based on the heat absorption limit of the heat dissipation medium.

[0053] In some embodiments, phase-change materials have the characteristic of absorbing large amounts of heat during phase changes while maintaining a relatively stable temperature. By exchanging heat with the phase-change material, the air conditioner can quickly remove the heat absorbed by the graphics card, enhancing the cooling effect. Compared to directly cooling the graphics card, using the phase-change material as an intermediate medium can more evenly and stably control the graphics card's temperature, reducing the impact of temperature fluctuations on graphics card performance. This cooling method also has certain energy-saving benefits, as the air conditioner is only activated for additional cooling when the actual graphics card temperature exceeds a threshold. This avoids frequent activation and prolonged operation of the air conditioner, thus ensuring effective cooling while reducing energy consumption.

[0054] In this embodiment, by measuring the phase change value of the phase change material, the need for air conditioning and cooling can be accurately determined based on this value. This compensates for the lag inherent in single temperature monitoring. For example, if the graphics card temperature is within the specified range but the phase change material is no longer able to absorb heat, the compressor can be activated in advance, avoiding frequent starts and stops. Furthermore, determining whether to activate air conditioning and cooling based on the phase change value can prevent the graphics card temperature from running out of control due to the complete melting of the phase change material due to heat absorption.

[0055] In an optional embodiment, turning on the air conditioner to perform heat exchange with the phase change material specifically includes:

[0056] determining an operating strategy for the air conditioner;

[0057] When the operation strategy is a heat dissipation priority strategy, controlling the compressor of the air conditioner to start so as to perform heat exchange on the phase change material;

[0058] When the operating strategy is an energy-saving priority strategy, the actual temperature is monitored to be greater than the preset temperature threshold, and the duration of the phase change value reaching the preset phase change threshold is monitored. When the duration reaches the preset duration threshold, the compressor of the air conditioner is controlled to turn on to perform heat exchange on the phase change material.

[0059] In this embodiment, the preset duration threshold can represent the air conditioner compressor startup buffer time. Due to the diverse operating conditions of graphics cards, sometimes the graphics card's temperature only rises within a certain period of time, or the graphics card's operating temperature fluctuates significantly over a period of time. In these cases, directly starting and stopping the compressor based on the graphics card's real-time operating temperature would significantly increase energy consumption and reduce the compressor's lifespan. Therefore, before starting the air conditioner to cool the graphics card, the user can still select the air conditioner's operating strategy.

[0060] In some embodiments, the preset time threshold is positively correlated with the viscosity of the phase change material, that is, the phase change value. The preset time threshold is set. During this time, the working temperature of the graphics card is absorbed and stored by the phase change material. After the phase change material stores a certain amount of heat, it is taken away by the external air conditioner, thereby significantly reducing the adverse effects caused by changes in the working temperature of the graphics card.

[0061] It should be noted that the judgment condition for starting the compressor is not limited to the optimal heat absorption value of the phase change material. The configuration of the optimal heat absorption value of the phase change material is to avoid the user not setting it as needed, but needing to use it to correctly judge whether to start the compressor and let the compressor work to dissipate heat. The optimal heat absorption value is only to ensure that the heat dissipation effect and energy saving can reach the best balance point. Users can choose different phase change thresholds of phase change materials to determine the operation strategy of the air conditioner.

[0062] Specifically, when the operating strategy prioritizes heat dissipation, the air conditioner is immediately turned on to perform heat exchange with the wax phase change material, thereby achieving secondary heat dissipation for the graphics card. When the operating strategy prioritizes energy conservation, the actual temperature of the graphics card is continuously monitored, compared with a preset temperature threshold, and the phase change value of the phase change material is simultaneously monitored. When the actual temperature exceeds the preset temperature threshold and the phase change value reaches the preset phase change threshold duration, and the duration reaches the preset duration threshold, the air conditioner's compressor is controlled to turn on to perform heat exchange with the phase change material, thereby achieving secondary heat dissipation for the graphics card.

[0063] In this embodiment, users can select the most appropriate cooling method based on their specific circumstances. For example, in scenarios where computer performance requirements are high and graphics card performance degradation due to heat dissipation is undesirable, a cooling priority strategy can be selected to ensure timely and effective cooling of the graphics card, maintaining high performance. In energy-sensitive scenarios, an energy-saving priority strategy can minimize air conditioning operation time and energy consumption while ensuring graphics card safety. When using the cooling priority strategy, once the actual graphics card temperature exceeds a preset temperature threshold and the phase change value reaches the preset phase change threshold, the air conditioner is immediately turned on to perform heat exchange on the wax phase change material. This can quickly force cooling of the graphics card, effectively preventing the graphics card from operating at high temperatures for extended periods, and minimizing the impact of high temperatures on the performance and lifespan of the graphics card. This ensures stable graphics card operation, avoids issues such as lag and freezes caused by overheating, and provides users with a smooth user experience.

[0064] Furthermore, in the energy-saving priority strategy, the actual temperature and phase change value are monitored to determine the duration of time they reach the corresponding threshold. Only when the duration reaches the preset duration threshold will the air conditioner be turned on for heat exchange. This can avoid the air conditioner from being frequently turned on due to short-term temperature fluctuations, reducing unnecessary energy consumption. This method takes into account the needs of graphics card heat dissipation and energy saving to a certain extent. This method allows the graphics card to be at a relatively high temperature but still within a safe range for a certain period of time. The decision to turn on the air conditioner is made by judging the continuous high temperature situation. This not only ensures that the graphics card will not be damaged due to long-term high temperature, but also effectively reduces the operating frequency of the air conditioner, achieving the purpose of energy saving.

[0065] Among them, such as Figure 3 As shown, using air conditioning to dissipate heat for graphics cards involves four steps: Compression: The compressor compresses the low-pressure gas refrigerant into high-pressure gas, raising its temperature; Condensation: The high-pressure, high-temperature refrigerant enters the condenser, where it gradually cools and becomes liquid through heat exchange with the outside air; Expansion: The liquid refrigerant passes through the expansion valve, reducing its pressure to a low-temperature, low-pressure liquid. Evaporation: The low-temperature, low-pressure refrigerant enters the evaporator, absorbs heat from the room, and turns into a gas, thereby lowering the indoor temperature. This cycle continues. By connecting the heat-absorbing evaporator to the graphics card, the air conditioner's temperature control target shifts from the room to the graphics card, effectively cooling the graphics card through air conditioning.

[0066] In some embodiments, before turning on the air conditioner to perform heat exchange with the phase change material, targeted operations can also be performed according to the standby state of the air conditioner to ensure that the cooling system can dissipate heat from the graphics card in a timely and effective manner. When the air conditioner is in operation, the working state of the compressor is adjusted, and the speed of the compressor and other parameters are accurately adjusted according to the current actual temperature and cooling requirements of the graphics card. For example, if the temperature of the graphics card is high, the speed of the compressor is increased to enhance the cooling capacity, quickly reduce the temperature of the graphics card, and ensure that the graphics card runs stably in a high-performance state; if the temperature is relatively low, the speed of the compressor is appropriately reduced to meet the cooling requirements while avoiding energy waste caused by excessive cooling. When the air conditioner is in standby mode, the compressor is controlled to start in time, and the secondary cooling process is quickly started to prevent the performance of the graphics card from degrading or malfunctioning due to long-term high temperature, thereby maintaining the stability of the graphics card performance.

[0067] It should be noted that determining whether the air conditioner is in standby mode is to avoid the situation where the user does not select the air conditioner's operating strategy after the phase change value reaches the preset phase change threshold. At this time, the compressor will be in the on state. Then, when the user is in the on state, he selects the energy-saving priority strategy. If the phase change value reaches the duration of the preset phase change threshold at this time, and the duration reaches the preset duration threshold, the compressor will be started. However, since the compressor is already in the on state at this time, it will be turned on again when the duration reaches the preset duration threshold. This will cause the compressor to misjudge and shut down in order to restart. Therefore, in order to avoid the above-mentioned frequent starting and stopping of the compressor, it is possible to first determine whether the air conditioner is in standby mode before turning on the compressor to further reduce energy consumption.

[0068] In some embodiments, the user can dynamically adjust the preset time threshold according to the usage scenario, for example, high-load gaming and low-load office work, to balance the heat dissipation effect and energy consumption.

[0069] In some embodiments, as Figure 4 As shown, it is determined whether the actual temperature of the graphics card exceeds the preset temperature threshold. If it does not exceed the preset temperature threshold, or when the viscosity value of the heat dissipation medium, that is, the phase change value, does not exceed the preset phase change threshold, or when the duration reaches the preset duration threshold, the air conditioner is put into standby mode to avoid invalid startup of the compressor and achieve energy saving.

[0070] In this embodiment, the air conditioner's operating strategy is determined by comprehensively considering the actual graphics card temperature and the phase change value of the wax phase change material, making heat dissipation control more flexible and precise. Two strategies, heat dissipation priority and energy conservation priority, are provided to better balance heat dissipation and energy consumption, tailored to different usage scenarios and user needs.

[0071] In an optional embodiment, before determining whether the phase change value reaches the preset phase change threshold, the method further includes determining the preset phase change threshold in the following manner:

[0072] Acquire first historical operation data of the air conditioner in the heat dissipation priority strategy and second historical operation data of the air conditioner in the energy saving priority strategy;

[0073] Drawing a phase change value-temperature change curve based on the first historical operation data, and drawing a phase change value-energy consumption change curve based on the second historical operation data;

[0074] Determining an intersection point of the phase change value-temperature change curve and the phase change value-energy consumption change curve;

[0075] The target phase change value corresponding to the intersection is determined as the optimal heat dissipation starting point as the preset phase change threshold.

[0076] In some embodiments, the first historical operating data and the second historical operating data of the air conditioner under the heat dissipation priority strategy and the energy saving priority strategy are obtained respectively, and then the actual operating conditions of the air conditioner under different strategies are obtained, including key indicators such as phase change value, temperature, and energy consumption, providing a data basis for subsequent analysis and decision-making.

[0077] In some embodiments, a phase change value-temperature curve, plotted based on the first historical operating data, can intuitively demonstrate the relationship between the phase change value of the wax phase change material and the graphics card temperature under a heat dissipation-first strategy. A phase change value-energy consumption curve, plotted based on the second historical operating data, reflects the relationship between the phase change value and air conditioning energy consumption under an energy conservation-first strategy. By plotting these two curves, complex data can be visualized for easier analysis and comparison.

[0078] Furthermore, the intersection of the phase change value-temperature curve and the phase change value-energy consumption curve represents a unique phase change value, representing a balance between heat dissipation and energy consumption. This intersection takes into account both the graphics card's cooling requirements and the air conditioner's energy consumption. Therefore, determining the target phase change value corresponding to this intersection as the optimal cooling start point ensures effective heat dissipation for the graphics card while minimizing air conditioner energy consumption.

[0079] Specifically, when the actual temperature of the graphics card is detected to be greater than a preset temperature threshold and the phase change value reaches the optimal heat dissipation starting point, the air conditioner is turned on to exchange heat with the phase change material. This can meet the graphics card's heat dissipation needs while optimizing the air conditioner's operating time and avoiding unnecessary energy waste.

[0080] In this embodiment, by obtaining the optimal cooling start point, heat dissipation efficiency is improved while also conserving energy, thereby enhancing the efficiency and cost-effectiveness of the entire cooling device. Analysis and decision-making based on historical data enables the cooling device to automatically adjust its operating strategy based on actual conditions to accommodate varying operating environments and graphics card loads, providing a more precise and efficient cooling solution. Compared to fixed cooling start conditions, the optimal cooling start point can be dynamically adjusted based on actual operating data, significantly improving the intelligence, adaptability, and reliability of the cooling device.

[0081] In an optional embodiment, a viscometer and a temperature-sensing package are provided in the connecting channel; obtaining the actual temperature of the graphics card includes: detecting the actual temperature of the graphics card using the temperature-sensing package; obtaining the phase change value of the phase change material includes: detecting the viscosity value of the phase change material using the viscometer, and the phase change value includes the viscosity value.

[0082] Combine Figure 3 and Figure 5As shown, in this embodiment, the graphics card and air conditioner are connected via a connecting channel, and the air conditioner is controlled by a controller. The air conditioner utilizes a micro-compressor and simplified hardware. The condenser, expansion valve, and evaporator within the air conditioner work in tandem with the micro-compressor, reducing the air conditioner's size. By directly connecting the air conditioner's evaporator to the graphics card to form a connecting channel, and filling the channel with a waxy phase-change material, a heat transfer path from graphics card to phase-change material to evaporator is established. This shifts the air conditioner's temperature control focus from the "indoor space" to the "graphics card," creating a cooling system for the graphics card. This addresses the issue of excessive bulk in traditional air conditioners, achieves hardware miniaturization, meets the spatial limitations of graphics card cooling, and enables precise targeting of cooling targets. Leveraging the efficient temperature control advantages of air conditioning technology, this significantly improves graphics card cooling efficiency.

[0083] In some embodiments, when the temperature sensor monitors the graphics card's real-time operating temperature in the connection channel, the data is transmitted to the controller via the processor in real time. This data is then quickly compared with a preset temperature threshold to determine whether the graphics card requires cooling. This allows the air conditioner to be controlled and the wax phase change material to respond promptly to the graphics card's cooling needs. Because the graphics card is directly connected to the air conditioner's evaporator, there's no need for a separate cooling component like a compressor or condenser, achieving an integrated "graphics card-air conditioner" cooling architecture.

[0084] In this embodiment, a temperature sensor package in the connection channel collects real-time temperature data from the graphics card core, replacing the indirect temperature measurement of traditional graphics card built-in sensors. This allows direct monitoring of the heat source and reduces temperature errors. By comparing the real-time temperature with a preset threshold, the graphics card's cooling requirements are accurately determined, and the most appropriate cooling method is provided based on these requirements, improving the graphics card's cooling efficiency.

[0085] In some embodiments, the above viscosity values can be measured by a rotational viscometer, for example, a rotational viscometer. The rotational viscometer is a cone-plate viscometer, which mainly includes a flat plate and a cone plate. The motor drives the flat plate to rotate at a constant speed through a speed change gear, and relies on capillary action to keep the sample to be measured between the two plates, and drives the cone plate to rotate by the friction between the sample molecules (i.e., the viscosity of the material). In the internal structure of the cone-plate viscometer, under the action of the torsion spring in the torque detector, the cone plate stops rotating after rotating a certain angle. At this time, the viscosity can be expressed by the torque applied by the torsion spring. A variable capacitor is provided in the torque detector, and its movable plate rotates with the cone plate, so that the viscosity is expressed by the change in the capacitance value.

[0086] It should be noted that the rotational viscometer can be replaced with other types of viscometers. After replacement, since the measurement principle is based on the fluidity of phase change materials, the system structure may need to reserve space for the material to flow or be designed into a flowable structure, which increases the complexity and instability of the system, but the overall effect can still be maintained.
