Description

Technical Field

[0001] This application belongs to the field of battery equipment technology, and more specifically, relates to a heat dissipation mechanism and a battery device. Background Technology

[0002] Currently, battery devices are generally required to have rapid charging and discharging capabilities, which leads to a large amount of heat being generated in the battery device. If the heat is not dissipated in time, it will not only affect the charging and discharging performance of the battery device, but also shorten its service life.

[0003] Based on the above factors, an increasing number of battery devices are equipped with heat dissipation mechanisms, such as cooling fans; cooling fans dissipate heat by blowing air onto the battery components in the battery device. However, this type of heat dissipation mechanism is limited by the airflow path, resulting in relatively low heat dissipation efficiency. Utility Model Content

[0004] The purpose of this application is to provide a heat dissipation mechanism and a battery device, which aims to solve the technical problem of low heat dissipation efficiency of heat dissipation mechanisms in related technologies.

[0005] To achieve the above objectives, according to one aspect of this application, a heat dissipation mechanism is provided for dissipating heat from a component to be cooled. The heat dissipation mechanism includes a mounting component, a heat sink, and a cooling fan. The heat sink is mounted on the mounting component and has a heat absorption end and a heat dissipation end. The heat absorption end can absorb heat from the component to be cooled by contacting it and can conduct the heat to the heat dissipation end. The cooling fan is mounted on the mounting component and can release the heat from the heat dissipation end to the surrounding environment.

[0006] When using the heat dissipation mechanism of this application to dissipate heat from a component, the component is first brought into contact with the heat-absorbing end. The heat-absorbing end absorbs the heat generated by the component and conducts it to the heat-dissipating end. The heat from the heat-dissipating end is then released to the surrounding environment by a cooling fan, thus achieving effective heat dissipation. Since the heat dissipation component in this application primarily relies on the contact between the heat-absorbing end and the component to absorb heat, rather than relying on airflow, the heat dissipation effect is no longer limited by the airflow path. Furthermore, the temperature difference between the heat-absorbing end and the heat-dissipating end is the driving force for heat transfer within the heat dissipation component. This temperature difference-driven approach helps improve heat conduction efficiency, thereby enhancing the overall heat dissipation efficiency of the heat dissipation component. In addition, the combined use of the heat dissipation component and the cooling fan can quickly release the heat from the heat-dissipating end to the surrounding environment, further enhancing the heat dissipation effect. By employing the heat dissipation component and cooling fan of this application, the heat dissipation efficiency of the heat dissipation mechanism is significantly improved, helping to better meet the heat dissipation needs of the component.

[0007] Optionally, the heat dissipation mechanism also includes a heat sink mounted on the mounting component and capable of absorbing heat from the heat dissipation end; a cooling fan mounted on the heat sink and capable of releasing the heat from the heat sink to the surrounding environment.

[0008] The heat sink and cooling fan used in this application significantly improve the heat dissipation effect at the heat dissipation end, thereby improving the heat dissipation efficiency of the heat dissipation mechanism.

[0009] Optionally, the heat dissipation mechanism also includes a heat-conducting element that is attached to and covers the heat dissipation element. The heat-absorbing end can absorb the heat of the component to be dissipated by contacting the component through the heat-conducting element. The heat sink is attached to the heat-conducting element and can absorb the heat of the heat dissipation end through the heat-conducting element.

[0010] The heat-conducting components not only help to distribute heat evenly, avoid local overheating, and improve the heat dissipation efficiency of the heat sink, but also help to indirectly increase the contact area between the component to be cooled and the heat sink and reduce the contact thermal resistance, thereby improving the heat conduction efficiency. In addition, the above design also helps to transfer heat to the heat sink and cooling fan, thereby accelerating the heat dissipation.

[0011] Optionally, the heat dissipation mechanism also includes a thermoelectric battery, which is located between the heat sink and the heat sink and has a hot end and a cold end that are arranged opposite to each other; the hot end is located on the side of the cold end closer to the heat sink, and the hot end can absorb the heat of the heat sink, while the heat sink can absorb the heat of the cold end; the thermoelectric battery is electrically connected to the cooling fan to supply power to the cooling fan.

[0012] The thermoelectric battery can convert the heat from the heat dissipation end into electrical energy, which can not only be used directly by the cooling fan to improve the heat dissipation effect of the heat dissipation end, but also improve the heat dissipation capacity of the heat dissipation component by absorbing the heat from the heat dissipation end.

[0013] Optionally, the heat sink includes multiple spaced heat pipes, all of which are fixedly laid on the mounting component; and / or, the mounting component is a thermally conductive structure; and / or, the thermally conductive component is a thermally conductive film coating or a thermally conductive grease coating.

[0014] The heat pipes not only free the heat dissipation effect of the heat sink from the limitations of airflow paths, but also, the temperature difference between the heat absorption and heat dissipation ends drives heat transfer within the heat sink. This temperature difference-driven process helps improve heat conduction efficiency, thereby enhancing the overall heat dissipation efficiency of the heat sink. The thermally conductive mounting structure not only enhances the heat sink's performance, ensuring efficient heat dissipation under various operating conditions, but also helps reduce the temperature difference between the heat sink and the mounting, thus lowering thermal resistance and improving the heat sink's performance. Furthermore, this design effectively disperses heat, preventing localized overheating and improving the stability and reliability of the heat dissipation mechanism. The design of the thermally conductive component using a thermally conductive film coating or thermal grease coating reduces installation difficulty and cost while improving the heat dissipation and heat conduction efficiency of the heat sink.

[0015] According to another aspect of this application, a battery device is provided, including a battery assembly and the aforementioned heat dissipation mechanism, wherein the heat-absorbing end absorbs heat from the battery assembly by contacting the battery assembly, and the battery assembly is formed as a component to be dissipated.

[0016] When using the heat dissipation mechanism of this application to dissipate heat from a battery module, the battery module first comes into contact with the heat-absorbing end. The heat-absorbing end absorbs the heat generated by the battery module and conducts it to the heat-dissipating end. The heat from the heat-dissipating end is then released to the surrounding environment by a cooling fan, thus achieving effective heat dissipation. Since the heat dissipation component in this application primarily relies on the contact between the heat-absorbing end and the battery module to absorb the heat generated by the battery module, rather than relying on airflow, the heat dissipation effect is no longer limited by the airflow path. Furthermore, the temperature difference between the heat-absorbing end and the heat-dissipating end is the driving force for heat transfer within the heat dissipation component. This temperature difference-driven approach helps improve heat conduction efficiency, thereby enhancing the overall heat dissipation efficiency of the heat dissipation component. In addition, the combined use of the heat dissipation component and the cooling fan can quickly release the heat from the heat dissipating end to the surrounding environment, further enhancing the heat dissipation effect of the heat dissipating end. By adopting the heat dissipation component and cooling fan of this application, the heat dissipation efficiency of the heat dissipation mechanism is significantly improved, helping to better meet the heat dissipation requirements of the battery module.

[0017] Optionally, the battery device also includes a protective box with a protective space in which the battery assembly is located; the protective box has an exposed through hole communicating with the protective space, and part of the structure of the mounting component is installed into the protective space through the exposed through hole, while the cooling fan is located outside the protective space.

[0018] The protective box in the above design serves to protect the battery components; the exposed through holes allow the mounting components to be installed into the protected space; and the cooling fan is located outside the protected space, which helps to ensure the heat dissipation effect of the heat dissipation end, thereby improving the heat dissipation efficiency of the heat dissipation components.

[0019] Optionally, a first limiting member is installed within the protective space. The first limiting member has a first limiting surface located on the side of the mounting member closest to the battery assembly. The first limiting surface can prevent the battery assembly from continuing to approach the cooling fan.

[0020] The first limiting component applies resistance to the battery assembly by limiting the battery assembly to prevent it from getting closer to the cooling fan. The first limiting component plays a limiting role and ensures the stability of the battery assembly within the protected space.

[0021] Optionally, a second limiting member is installed within the protective space. The second limiting member is located on the side of the first limiting member away from the cooling fan. The second limiting member has a second limiting surface located on the side of the mounting member closer to the battery assembly. The second limiting surface can prevent the battery assembly from continuing to move away from the cooling fan.

[0022] The second limiting member applies resistance to the battery assembly by limiting the battery assembly to prevent it from moving further away from the cooling fan. The second limiting member also serves as a limiting element, and its use in conjunction with the first limiting member further ensures the stability of the battery assembly within the protected space.

[0023] Optionally, the battery assembly is connected to the first limiting member via a first fastener; and / or, the battery assembly is connected to the second limiting member via a second fastener; and / or, an aerosol fire extinguishing component is installed in the protected space; and / or, the protected space has an installation opening, and a sealing cover capable of sealing the installation opening is detachably installed on the protective box, with an insulating sheet installed on the surface of the sealing cover near the battery assembly.

[0024] The first fastener enhances the stability of the battery assembly within the protected space. The second fastener, used in conjunction with the first, further strengthens this stability. The aerosol fire extinguishing component provides rapid and effective fire suppression, significantly improving the safety of the battery device. The sealing cap and mounting opening used in this application facilitate maintenance and replacement of the battery assembly within the protected space, improving the convenience of maintenance and replacement operations. The insulating sheet further enhances the safety of the battery device.

[0025] The beneficial effects of the heat dissipation mechanism and battery device provided in this application are as follows: When using the heat dissipation mechanism of this application to dissipate heat from a component to be cooled, the component to be cooled is first brought into contact with the heat-absorbing end. The heat-absorbing end absorbs the heat generated by the component to be cooled and conducts the heat to the heat-dissipating end. The heat from the heat-dissipating end is released to the surrounding environment through a cooling fan, thereby achieving effective heat dissipation. Since the heat dissipation component in this application mainly relies on the contact between the heat-absorbing end and the component to be cooled to absorb the heat generated by the component to be cooled, rather than relying on airflow, the heat dissipation effect of the heat dissipation component is no longer limited by the airflow path. At the same time, the temperature difference between the heat-absorbing end and the heat-dissipating end is the driving force for heat transfer in the heat dissipation component. This temperature difference-driven approach helps to improve the heat conduction efficiency, thereby helping to improve the overall heat dissipation efficiency of the heat dissipation component. In addition, the combined use of the heat dissipation component and the cooling fan can quickly release the heat from the heat dissipating end to the surrounding environment, which helps to further enhance the heat dissipation effect of the heat dissipating end. By adopting the heat dissipation component and the cooling fan in this application, the heat dissipation efficiency of the heat dissipation mechanism is significantly improved, which helps to better meet the heat dissipation needs of the component to be cooled.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0048] As described in the background section, current battery devices generally require rapid charging and discharging capabilities, which leads to the generation of a large amount of heat. If this heat is not dissipated in time, it will not only affect the charging and discharging performance of the battery device but also shorten its lifespan. Based on these factors, more and more battery devices are equipped with heat dissipation mechanisms, such as cooling fans. Cooling fans dissipate heat by blowing air onto the battery components within the device. However, such heat dissipation mechanisms are limited by the airflow path, resulting in relatively low heat dissipation efficiency.

[0049] Reference Figures 1 to 3 To address the aforementioned problems, according to one aspect of this application, an embodiment of this application provides a heat dissipation mechanism for dissipating heat from a component 200 to be cooled. The heat dissipation mechanism 100 includes a mounting member 110, a heat sink 120, and a cooling fan 130. The heat sink 120 is mounted on the mounting member 110 and has a heat absorption end and a heat dissipation end. The heat absorption end can absorb heat from the component 200 by contacting it and can conduct the heat to the heat dissipation end. The cooling fan 130 is mounted on the mounting member 110 and can release the heat from the heat dissipation end to the surrounding environment.

[0050] In this embodiment, the heat dissipation mechanism 100 is used in a battery device to dissipate heat from the battery assembly, which is formed as a component to be dissipated 200. In other embodiments, the heat dissipation mechanism 100 can also dissipate heat from other components that need to be dissipated, which are also formed as components to be dissipated 200. The mounting member 110 is a mounting plate; the heat dissipation member 120 can be a heat dissipation member with a heat absorption end and a heat dissipation end, such as a semiconductor cooling chip or a heat pipe; the contact between the component to be dissipated 200 and the heat absorption end can be direct contact or indirect contact, and the component to be dissipated 200 can be placed on the heat absorption end for direct or indirect contact with the heat absorption end.

[0051] When using the heat dissipation mechanism 100 of this application to dissipate heat from the component 200, the component 200 is first brought into contact with the heat-absorbing end. The heat-absorbing end absorbs the heat generated by the component 200 and conducts it to the heat-dissipating end. The heat from the heat-dissipating end is then released to the surrounding environment through the cooling fan 130, thereby achieving effective heat dissipation. Since the heat sink 120 in this application primarily relies on the contact between the heat-absorbing end and the component 200 to absorb the heat generated by the component 200, rather than relying on airflow, the heat dissipation effect of the heat sink 120 is no longer limited by the airflow path. Furthermore, the temperature difference between the heat-absorbing end and the heat-dissipating end is the driving force for heat transfer in the heat sink 120. This temperature difference helps improve heat conduction efficiency, thereby improving the overall heat dissipation efficiency of the heat sink 120. In addition, the combined use of the heat sink 120 and the cooling fan 130 can quickly release the heat from the heat sink to the surrounding environment, further enhancing the heat dissipation effect of the heat sink. By adopting the heat sink 120 and cooling fan 130 in this application, the heat dissipation efficiency of the heat dissipation mechanism 100 is significantly improved, which helps to better meet the heat dissipation needs of the component 200 to be cooled.

[0052] Reference Figures 1 to 3 In one embodiment, the heat dissipation mechanism 100 further includes a heat sink 140, which is mounted on the mounting member 110 and is capable of absorbing heat from the heat dissipation end; a cooling fan 130 is mounted on the heat sink 140 and is capable of releasing the heat on the heat sink 140 to the surrounding environment.

[0053] In this embodiment, the heat sink 140 is shaped as a plane, fin, columnar, plate, or tower. To improve heat dissipation efficiency, the heat sink 140 covers the heat dissipation end and can be in contact with it. The cooling fan 130 is fixedly mounted on the heat sink 140 via a connecting plate and connecting screws, and is located on one side of the mounting member 110. The heat sink 140 and cooling fan 130 used in this application significantly improve the heat dissipation effect at the heat dissipation end, thereby improving the heat dissipation efficiency of the heat dissipation mechanism 100.

[0054] Reference Figures 1 to 4 In one embodiment, the heat dissipation mechanism 100 further includes a heat-conducting element 150, which is attached to and covers the heat dissipation element 120. The heat-absorbing end can contact the heat-dissipating component 200 through the heat-conducting element 150 to absorb the heat of the heat-dissipating component 200. The heat sink 140 is attached to the heat-conducting element 150 and can absorb the heat of the heat dissipation end through the heat-conducting element 150.

[0055] In this embodiment, the heat-conducting element 150 may be a heat-conducting sheet or heat-conducting pad made of heat-conducting material; the component to be dissipated 200 is placed on the heat-conducting element 150 and directly contacts the heat-conducting element 150, thereby indirectly contacting the heat-absorbing end; the heat sink 140 is mounted on the surface of the heat-conducting element 150 away from the mounting member 110.

[0056] When using the heat dissipation mechanism 100 of this application to dissipate heat from the component 200 to be cooled, the component 200 is first brought into contact with the heat-conducting element 150. The heat-conducting element 150 conducts heat to the heat-absorbing end, which absorbs the heat and conducts it to the heat-dissipating end. The heat-dissipating end then conducts the heat to the heat sink 140 through the heat-conducting element 150 and releases it to the surrounding environment through the cooling fan 130, thereby achieving effective heat dissipation. The heat-conducting element 150 not only helps to distribute heat evenly, avoid local overheating, and improve the heat dissipation efficiency of the heat sink 120, but also indirectly increases the contact area between the component 200 to be cooled and the heat sink 120 and reduces the contact thermal resistance, thereby improving the heat conduction efficiency. In addition, the above design also helps to transfer heat to the heat sink 140 and the cooling fan 130, thereby accelerating the heat dissipation.

[0057] Reference Figures 1 to 4 In one embodiment, the heat dissipation mechanism 100 further includes a thermoelectric battery 160, which is located between the heat sink 120 and the heat sink 140, and has a hot end and a cold end disposed opposite to each other; the hot end is located on the side of the cold end closer to the heat sink 120, and the hot end can absorb the heat of the heat sink 140, which can absorb the heat of the cold end; the thermoelectric battery 160 is electrically connected to the cooling fan 130 to supply power to the cooling fan 130.

[0058] In this embodiment, when there is no thermally conductive element 150 between the heat sink 120 and the heat sink 140, the hot end directly contacts and adheres to the heat sink end; when there is a thermally conductive element 150 between the heat sink 120 and the heat sink 140, the hot end contacts and adheres to the heat sink end through the thermally conductive element 150; the heat sink 140 covers the cold end and adheres to it. The thermoelectric battery 160 can convert the heat from the heat sink end into electrical energy, which can not only be directly used by the cooling fan 130 to improve the heat dissipation effect of the heat sink end, but also enhance the heat dissipation capacity of the heat sink 120 by absorbing the heat from the heat sink end.

[0059] Reference Figure 2 In one embodiment, the heat sink 120 includes a plurality of spaced heat pipes, all of which are fixedly laid on the mounting component 110.

[0060] In this embodiment, a heat pipe is a highly efficient heat transfer device. Its basic structure includes a sealed tube filled with a working fluid (such as water or ammonia), creating a vacuum or low-pressure environment inside. The working principle of the heat pipe is as follows: when the first end of the heat pipe is heated by a heat source, the internal working fluid evaporates and becomes a gas; the vapor moves through the pipe to the second end of the heat pipe; upon reaching the second end, the vapor releases heat and condenses into a liquid; the condensed liquid returns to the first end of the heat pipe through gravity or capillary action, completing the cycle. As can be seen, the first end of the heat pipe is the heat absorption end, and the second end is the heat dissipation end; simultaneously, the heat dissipation end is located on the side of the heat absorption end closer to the cooling fan 130.

[0061] Furthermore, the heat pipes are flat tubes; the mounting component 110 has a mounting surface 111, and the heat-conducting component 150 fits and covers the mounting surface 111; the mounting surface 111 has multiple mounting slots, the number of which is the same as the number of heat pipes, and multiple heat pipes are respectively set one-to-one with multiple mounting slots to be installed in the corresponding mounting slots; the surface of the heat pipe away from the bottom of the mounting slot is flush with the mounting surface 111. The heat pipes not only make the heat dissipation effect of the heat sink 120 no longer limited by the air flow path, but also the temperature difference between the heat absorption end and the heat dissipation end is the driving force for heat transfer in the heat sink 120. This temperature difference driving helps to improve the heat conduction efficiency, thereby helping to improve the overall heat dissipation efficiency of the heat sink 120. In other embodiments, the heat pipes can also be directly fixed and laid on the mounting surface 111, so as to be protruding. In addition, in other embodiments, the heat sink 120 can also be a semiconductor cooling chip, with the heat absorption end corresponding to the mounting surface 111, and the heat dissipation end corresponding to the surface on the mounting component 110 that is opposite to the mounting surface 111.

[0062] Reference Figures 1 to 4 In one embodiment, the mounting member 110 is a thermally conductive structure. In this embodiment, the mounting member 110 is made of an aluminum or copper plate with high thermal conductivity. This design not only helps enhance the working effect of the heat sink 120, ensuring efficient heat dissipation under different operating conditions, but also helps reduce the temperature difference between the heat sink 120 and the mounting member 110, thereby reducing thermal resistance and improving the performance of the heat sink 120. Furthermore, this design effectively disperses heat, avoids localized overheating, and improves the stability and reliability of the heat dissipation mechanism 100.

[0063] Reference Figures 1 to 4In one embodiment, the heat-conducting element 150 is a thermally conductive film coating or a thermally conductive grease coating. In this embodiment, the thermally conductive film coating or thermally conductive grease coating is fixedly applied to the mounting surface 111 and covers the mounting surface 111. The above design reduces the installation difficulty and cost while improving the heat dissipation efficiency and heat conduction efficiency of the heat sink 120.

[0064] Reference Figures 1 to 8 According to another aspect of this application, embodiments of this application also provide a battery device, including a battery assembly and the aforementioned heat dissipation mechanism 100, wherein the heat-absorbing end absorbs heat from the battery assembly by contacting the battery assembly, and the battery assembly is formed as a heat dissipation component 200.

[0065] In the embodiments of this application, the battery assembly includes multiple battery packs arranged at intervals; at the same time, the contact method between the battery assembly and the heat-absorbing end can be direct contact or indirect contact, and the battery assembly can be placed on the heat-absorbing end to make direct or indirect contact with the heat-absorbing end.

[0066] When using the heat dissipation mechanism 100 of this application to dissipate heat from the battery module, the battery module first comes into contact with the heat-absorbing end. The heat-absorbing end absorbs the heat generated by the battery module and conducts it to the heat-dissipating end. The heat from the heat-dissipating end is then released to the surrounding environment through the cooling fan 130, thereby achieving effective heat dissipation. Since the heat dissipation component 120 in this application primarily relies on the contact between the heat-absorbing end and the battery module to absorb the heat generated by the battery module, rather than relying on airflow, the heat dissipation effect of the heat dissipation component 120 is no longer limited by the airflow path. Simultaneously, the temperature difference between the heat-absorbing end and the heat-dissipating end is the driving force for heat transfer in the heat dissipation component 120. This temperature difference-driven approach helps improve heat conduction efficiency, thereby improving the overall heat dissipation efficiency of the heat dissipation component 120. Furthermore, the combined use of the heat dissipation component 120 and the cooling fan 130 can quickly release the heat from the heat dissipating end to the surrounding environment, further enhancing the heat dissipation effect of the heat dissipating end. By employing the heat dissipation component 120 and the cooling fan 130 of this application, the heat dissipation efficiency of the heat dissipation mechanism 100 is significantly improved, helping to better meet the heat dissipation requirements of the battery module.

[0067] Reference Figure 1 as well as Figures 5 to 8 In one embodiment, the battery device further includes a protective box 300, which has a protective space 310, and the battery assembly is located inside the protective space 310. The protective box 300 is provided with an exposed through hole communicating with the protective space 310. Part of the structure of the mounting member 110 is installed into the protective space 310 through the exposed through hole, and the cooling fan 130 is located outside the protective space 310.

[0068] The protective box 300 in the above design serves to protect the battery assembly; the exposed through hole allows the mounting component 110 to be installed into the protective space 310; and the cooling fan 130 is located outside the protective space 310, which helps to ensure the heat dissipation effect of the heat dissipation end, thereby improving the heat dissipation efficiency of the heat dissipation component 120.

[0069] Reference Figure 1 , Figure 8 as well as Figure 9 In one embodiment, a first limiting member 400 is installed in the protective space 310. The first limiting member 400 has a first limiting surface 410 located on the side of the mounting member 110 near the battery assembly. The first limiting surface 410 can prevent the battery assembly from continuing to approach the cooling fan 130.

[0070] In this embodiment, the first limiting member 400 is a limiting strip or a limiting plate, which can be fixedly installed in the protective space 310 by connecting screws or welding. Simultaneously, to allow part of the mounting member 110 to pass through the first limiting member 400 and continue extending into the protective space 310, the first limiting member 400 is provided with a through hole for the mounting member 110 to pass through. The first limiting member 400 applies resistance to the battery assembly through the first limiting surface 410, preventing the battery assembly from further approaching the cooling fan 130. The first limiting member 400 thus serves a limiting function, ensuring the stability of the battery assembly within the protective space 310.

[0071] Reference Figure 8 and Figure 10 In one embodiment, a second limiting member 500 is installed in the protective space 310. The second limiting member 500 is located on the side of the first limiting member 400 away from the cooling fan 130. The second limiting member 500 has a second limiting surface 510, which is located on the side of the mounting member 110 close to the battery assembly. The second limiting surface 510 can prevent the battery assembly from moving further away from the cooling fan 130.

[0078] In summary, implementing the heat dissipation mechanism and battery device provided in this embodiment has at least the following beneficial technical effects: When using the heat dissipation mechanism 100 of this application to dissipate heat from the component 200 to be dissipated, the component 200 to be dissipated is first brought into contact with the heat-absorbing end. The heat-absorbing end absorbs the heat generated by the component 200 to be dissipated and conducts the heat to the heat dissipation end. The heat from the heat dissipation end is released to the surrounding environment through the cooling fan 130, thereby achieving effective heat dissipation. Since the heat dissipation component 120 in this application mainly relies on the contact between the heat-absorbing end and the component 200 to absorb the heat generated by the component 200 to be dissipated, rather than relying on airflow, the heat dissipation effect of the heat dissipation component 120 is no longer limited by the airflow path. At the same time, the temperature difference between the heat-absorbing end and the heat dissipation end is the driving force for heat transfer in the heat dissipation component 120. This temperature difference drive helps to improve the heat conduction efficiency, thereby helping to improve the overall heat dissipation efficiency of the heat dissipation component 120. In addition, the combined use of the heat dissipation component 120 and the cooling fan 130 can quickly release the heat from the heat dissipation end to the surrounding environment, which helps to further enhance the heat dissipation effect of the heat dissipation end. By adopting the heat sink 120 and cooling fan 130 in this application, the heat dissipation efficiency of the heat dissipation mechanism 100 is significantly improved, which helps to better meet the heat dissipation needs of the component 200 to be cooled.

[0079] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
