Description

Technical Field

[0001] This utility model relates to the field of air-cooled heat dissipation technology, and in particular to an active heat dissipation structure for power devices. Background Technology

[0002] A GPU (Graphics Processing Unit) is a coprocessor used for processing images and graphics calculations, widely used in personal computers, workstations, and some mobile devices (such as smartphones and tablets). Currently, the mainstream GPU card cooling solutions fall into two categories: One type features an active fan and heatsink, known as an air-cooled active GPU card. When inserted into a device, this type of GPU card does not rely entirely on the device for airflow cooling; the airflow generated by the GPU's built-in fan is sufficient for its cooling needs. The other type of GPU card only has a heatsink without a fan; this type is called an air-cooled passive GPU card. When inserted into a device, the device must provide the necessary airflow to remove the heat generated by the GPU during operation.

[0003] Currently, air-cooled active cooling GPU cards can be installed and used in various types of devices, such as servers, workstations, and edge computing devices, because they do not rely on the device to provide airflow to meet their cooling needs. In contrast, air-cooled passive cooling GPU cards rely on the device to provide a large airflow to meet their cooling needs during operation. However, the airflow generated by the internal fans of typical workstations and edge computing devices is relatively low and cannot meet the cooling requirements of high-power, high-performance GPU cards. Therefore, high-power, high-performance GPU cards are currently mainly used in high-performance server devices, which have fans with high fan speed and strong airflow to meet the cooling requirements of high-power, high-performance GPU cards during operation.

[0004] However, high-power, high-performance air-cooled passive GPU cards are subject to certain limitations when used in various conventional computer devices, and this application aims to improve upon this limitation. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of the aforementioned background technology by providing a solution for actively cooling high-power, high-performance air-cooled passive GPU cards, which can also be adapted to other similar power devices.

[0006] To achieve the above objectives, this utility model provides an active heat dissipation structure for power devices, including an active fan compartment and an axial fan;

[0007] The first and second ends of the active fan compartment are connected to each other. The axial fan is arranged at the first end of the active fan compartment. The power device is detachably connected to the second end of the active fan compartment by mounting screws.

[0008] The active fan compartment includes a middle frame, an upper plate, and a lower plate. The upper plate and the lower plate are detachably connected to the middle frame by mounting screws. A fan opening is provided on the first end face of the middle frame, and the fan opening corresponds to the size of the axial fan. The second end face of the middle frame is open.

[0009] Furthermore, the number of axial fans installed in the active fan compartment is two or more.

[0010] Furthermore, the active fan compartment is configured to be thicker at the first end and thinner at the second end, so that the air flowing out of the active fan compartment is accelerated.

[0011] Furthermore, the lower plate is configured as a flat plate, the upper plate is configured as a folded plate, and the shape of the contact position between the middle frame and the upper plate is configured accordingly.

[0012] Furthermore, the middle frame is provided with multiple folded edges, which are divided into two groups located at the upper and lower parts of the middle frame. The folded edges are provided with screw holes, and the upper plate and the lower plate are also provided with corresponding screw holes.

[0013] Furthermore, the screw holes of the folded edge are configured as serrated holes, and the screw holes of the upper plate and the lower plate are configured as countersunk holes.

[0014] Furthermore, the upper plate has multiple slots, including a fan cable outlet slot and a power device cable outlet slot. The fan cable outlet slot is used to lead out the connecting wire of the axial fan, and the power device cable outlet slot is used to lead out the connecting wire of the power device.

[0015] The above-mentioned solution of this utility model has the following beneficial effects:

[0016] The active heat dissipation structure for power devices provided by this utility model is equipped with an active fan chamber and an axial fan. It can be easily connected to power devices, such as GPU cards. At the same time, it can also be easily connected to the corresponding interface inside the device to power and control the axial fan in the active fan chamber, so that the axial fan rotates and generates airflow through the power device, which quickly removes the heat generated by the power device, achieving the purpose of active and efficient heat dissipation. The structure is relatively compact and can usually be installed smoothly inside the device when combined with power devices, ensuring the normal operation of high-power, high-performance power devices and improving overall reliability.

[0017] Other beneficial effects of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0027] To make the technical problems, solutions, and advantages of this utility model clearer, a detailed description will be provided below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a locking connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] like Figures 1-4 As shown, this embodiment of the present invention provides an active cooling structure for power devices. The power device used is a GPU card 10, but other functional devices of similar size and cooling requirements can also be applied. The active cooling structure includes an active fan chamber 20 and an axial fan 30 disposed inside the active fan chamber 20. The first and second ends of the active fan chamber 20 are connected, the axial fan 30 is located at the first end of the active fan chamber 20, and the GPU card 10 is connected to the second end of the active fan chamber 20. Therefore, when the axial fan 30 rotates, it allows external air to enter the active fan chamber 20 and then exit from the second end of the active fan chamber 20, thereby directly forming an airflow through the GPU card 10, quickly carrying away the heat generated by the GPU card 10, achieving efficient cooling, especially suitable for high-power, high-performance passively cooled air-cooled GPU cards 10.

[0031] At the same time, such as Figures 5-7As shown, in this embodiment, the active fan chamber 20 includes a middle frame 21, an upper plate 22, and a lower plate 23. The upper plate 22 and lower plate 23 are detachably connected to the middle frame 21 via mounting screws 40, thus partially enclosing the upper and lower surfaces of the active fan chamber 20. Simultaneously, the middle frame 21 itself can partially enclose the side surfaces of the active fan chamber 20. A fan opening 24 is provided on the first end face of the middle frame 21, corresponding to the size of the axial fan 30, to ensure smooth airflow from the axial fan 30's suction end. The second end face of the middle frame 21 is open, allowing air inside the active fan chamber 20 to flow out and form an airflow passing through the GPU card 10. Therefore, the middle frame 21 itself is approximately n-shaped, for example... Figure 5 As shown.

[0032] In a preferred embodiment, the active fan compartment 20 is equipped with two axial fans 30, and correspondingly, two fan vents 24 are opened on the first end face of the middle frame 21, so as to further enhance the airflow intensity through the two axial fans 30, thereby improving the heat dissipation efficiency. Of course, a certain number of axial fans 30 can be set according to the size of the active fan compartment 20 and the first end face of the middle frame 21 to ensure that the axial fans 30 are arranged compactly but do not interfere with each other.

[0033] In a preferred embodiment, the active fan compartment 20 is configured with a thicker first end (greater distance between the upper plate 22 and the lower plate 23) and a thinner second end (smaller distance between the upper plate 22 and the lower plate 23). This increases the volume of the first end of the active fan compartment 20, facilitating the placement of the axial fan, while the reduced volume of the second end accelerates the airflow as it exits the active fan compartment 20, increasing the airflow rate through the GPU card 10 and further improving heat dissipation efficiency. The lower plate 23 of the active fan compartment 20 remains flat, while the upper plate 22 is folded with a sloping surface. The contact shape between the middle frame 21 and the upper plate 22 is also correspondingly configured, resulting in a final assembled active fan compartment 20 with a thicker first end and a thinner second end.

[0034] As previously described, the upper plate 22 and lower plate 23 are detachably connected to the middle frame 21 via corresponding mounting screws 40, facilitating the assembly, disassembly, and replacement of components in the entire active cooling structure. The middle frame 21 has multiple flanges 25, located in two groups at the top and bottom of the frame, each flange having screw holes. Correspondingly, the upper plate 22 and lower plate 23 also have screw holes. When the upper plate 22 and lower plate 23 are aligned with the middle frame 21, the screw holes are also aligned, allowing the upper plate 22 and lower plate 23 to be securely connected to the middle frame 21 via mounting screws 40, forming a stable active fan housing 20. For example, considering the middle frame 21 to be n-shaped, with one flange 25 at each of the three flange positions, the upper plate 22 and lower plate 23 are each fixed to the middle frame 21 via three mounting screws 40. Of course, in other embodiments, other numbers of folded edges 25 can be arranged according to the specific form of the middle frame 21, as long as the overall stability of the active fan compartment 20 can be ensured.

[0035] In one specific embodiment, the screw holes on the folded edge 25 of the middle frame 21 are countersunk holes 26, for example, tapping M3 threads, while the screw holes on the upper plate 22 and lower plate 23 are countersunk holes 27, so that the screw heads are submerged in the surface of the upper plate 22 or lower plate 23 after the mounting screws 40 are installed, further improving compactness. At the same time, it will not protrude and scratch other components inside the equipment when installed inside the equipment.

[0036] In addition, several screw holes (at least two) are added at the second end of the upper plate 22, which are also countersunk holes 27, for connecting to corresponding power devices. For example, a threaded hole is provided at one end of the GPU card 10, so the upper plate 22 can be connected to the GPU card 10 by installing screws 40, thereby making the entire active cooling structure firmly connected to the GPU card 10. The airflow direction delivered by the active fan chamber 20 corresponds to the GPU card 10, that is, it is parallel to the heat sink fin channel 11 of the GPU card 10, so that it enters the heat sink fin channel 11. After passing through the heat sink fin channel 11, the airflow flows out from the other end of the GPU card 10, thereby removing the heat generated by the GPU card 10 during operation and achieving the cooling effect.

[0037] In this embodiment, the upper plate 22 also has multiple slots, including a fan cable outlet slot 28 and a power device cable outlet slot 29. Obviously, the fan cable outlet slot 28 needs to be located closer to the first end of the active fan compartment 20 so that the connecting cable of the axial fan 30 can be smoothly led out and connected to the device's interface (e.g., an interface on the motherboard) to power and control the axial fan 30. For the power device, when its connecting cable is on this side, it can be led out through the power device cable outlet slot 29 and connected to the device's interface; of course, if the connecting cable is on the other side, it does not need to be led out through the power device cable outlet slot 29.

[0038] As described above, the active heat dissipation structure for power devices provided in this embodiment can actually be regarded as an accessory component of a power device. It can be easily connected to power devices, such as the GPU card 10, and can also be easily connected to corresponding interfaces inside the device to power and control the axial fan 30 in the active fan compartment 20, causing the axial fan 30 to rotate and generate airflow through the power device, quickly removing the heat generated by the power device, thus achieving active and efficient heat dissipation. The structure is relatively compact and can usually be smoothly installed inside the device when combined with the power device, ensuring the normal operation of high-power, high-performance power devices and improving overall reliability.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
