Description

Technical Field

[0001] This application relates to the field of heat dissipation technology for electronic devices, and in particular to a heat duct and electronic device. Background Technology

[0002] As the performance of computer CPUs (Central Processing Units) continues to improve, so too does their cooling technology. Initially, heatsinks were simply installed on the computer case for heat dissipation. However, as CPU power increased, heatsinks became insufficient, leading to the addition of fans. Fans generate airflow to remove the heat generated by the CPU. But fans also present several problems: first, the turbulent airflow they produce can hinder effective heat dissipation; second, because the motherboard itself generates heat, the air drawn in by the fan is often hot, further reducing cooling efficiency.

[0003] To address these issues, more and more computers are now using air shrouds. Air shrouds serve two main functions: first, they guide airflow, ensuring the cool air generated by the fan follows a fixed path, preventing airflow turbulence and thus improving heat dissipation efficiency; second, they draw in cooler air from outside the chassis, rather than the already heated air inside, which better lowers the CPU temperature. This design significantly improves heat dissipation, allowing stable operation even under high loads despite turbulent airflow.

[0004] However, existing air guide covers are usually installed on the fan with screws. The installation process requires tools and is cumbersome, which brings great inconvenience to users for later maintenance and upgrades. Utility Model Content

[0005] Therefore, it is necessary to provide an air guide cover and electronic equipment to address the aforementioned technical problems.

[0006] An air guide cover, comprising:

[0007] Air guide section, and

[0008] The mounting part is connected to the air guide part. The mounting part is provided with a latch. The latch includes a receiving groove and a fastening groove. The opening of the receiving groove penetrates the end wall of the mounting part away from the air guide part, and the opening of the fastening groove penetrates the circumferential groove wall of the receiving groove.

[0009] The aforementioned air guide cover features a latch on the side of the mounting section away from the air guide section. This latch engages with the heat sink of the electronic device as the air guide cover rotates around its central axis. Compared to traditional screw connections, this application allows for installation and removal of the air guide cover simply by screwing it on, eliminating the need for installation tools and individual screw tightening. This simplifies the installation process and greatly facilitates future maintenance and upgrades. Furthermore, based on the structural characteristics of existing heat sinks, the latch is designed with a receiving groove and a locking groove. No additional modifications to the heat sink structure are required; the air guide cover can be installed on the heat sink simply by creating the receiving groove and locking groove in the mounting section of the air guide cover, simplifying the structure of both the air guide cover and the heat sink.

[0010] In one embodiment, there are multiple latches, and the openings of the latching grooves of all the latches face the same direction.

[0011] With the above settings, when the air guide cover is turned clockwise or counterclockwise, each latch can engage with the corresponding connecting part, ensuring the smooth installation of the air guide cover.

[0012] In one embodiment, the opening of the fastening groove is provided with a flared section.

[0013] The above design makes it easier for the connecting part to enter the fastening groove, facilitating the assembly of the air guide cover and the heat sink.

[0014] In one embodiment, the receiving groove has a first distance between itself and the air guide portion along the axial direction of the air guide shroud, and the fastening groove has a second distance between itself and the air guide portion along the axial direction of the air guide shroud; wherein the second distance is greater than the first distance.

[0015] With the above settings, when the air guide cover is pressed down into place, the part of the receiving groove near the air guide part can avoid the head of the threaded part on the connecting part, so that when the air guide cover is screwed on, the connecting part on the outer ring body can smoothly enter the fastening groove of the air guide cover.

[0016] In one embodiment, the air guide shroud further includes a reinforcing portion disposed on the mounting portion, the reinforcing portion extending along the axial direction of the air guide shroud from one side of the mounting portion to the other side and close to the fastening groove.

[0017] By setting it as described above, the strength of the part of the mounting section with the fastening groove can be increased, the fastening groove can be prevented from failing, and the connection between the air guide cover and the heat sink can be guaranteed.

[0018] In one embodiment, the side of the mounting portion away from the air guide portion has a non-grooved portion, and the non-grooved portion has a mounting guide slope.

[0019] With the above configuration, the installation part can be inserted into the outer periphery of the outer ring body, which can guide the installation of the air guide cover and facilitate the installation of the air guide cover.

[0020] In one embodiment, the side of the air guide portion away from the mounting portion is provided with a flange, and the flange has an installation mark.

[0021] In one embodiment, the internal profile of the air guide is flared, with the side closer to the mounting portion being larger and the side farther away from the mounting portion being smaller.

[0022] By setting it up as described above, the airflow channel can be gradually expanded, reducing turbulence and resistance during airflow, making the airflow more stable and concentrated. This design not only improves the air delivery efficiency of the heat sink, but also guides the cooling air to the motherboard more precisely, thereby improving the heat dissipation effect. In addition, the horn-shaped air guide can also reduce the noise of the fan during operation and improve the overall user experience of electronic devices.

[0023] An electronic device includes a heat sink and an air guide shroud as described in any of the above claims. The outer peripheral wall of the heat sink has a connecting portion protruding from it. The mounting portion of the air guide shroud is arranged around the outer peripheral side of the heat sink. When the air guide shroud rotates around its own central axis, the connecting portion can enter the fastening groove of the air guide shroud through the receiving groove of the air guide shroud and be fastened and locked by the air guide shroud.

[0024] The aforementioned electronic device features a latch on the side of the mounting section away from the air guide section. This latch engages with the heat sink of the electronic device as the air guide rotates around its central axis. Compared to traditional screw connections, this application allows for the installation and removal of the air guide simply by turning it on and off, eliminating the need for installation tools and individual screw turning. This simplifies the installation process and greatly facilitates future maintenance and upgrades for users. Furthermore, based on the existing structural characteristics of the heat sink, the latch is designed to include a receiving groove and a fastening groove. This eliminates the need for additional structural modifications to the heat sink. The air guide can be installed on the heat sink simply by opening the receiving groove and fastening groove in the mounting section of the air guide, simplifying the structure of both the air guide and the heat sink.

However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0034] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0035] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0039] As the performance of computer CPUs (Central Processing Units) continues to improve, so too does their cooling technology. Initially, heatsinks were simply installed on the computer case for heat dissipation. However, as CPU power increased, heatsinks became insufficient, leading to the addition of fans. Fans generate airflow to remove the heat generated by the CPU. But fans also present several problems: first, the turbulent airflow they produce can hinder effective heat dissipation; second, because the motherboard itself generates heat, the air drawn in by the fan is often hot, further reducing cooling efficiency.

[0040] To address these issues, more and more computers are now using air shrouds. Air shrouds serve two main functions: first, they guide airflow, ensuring the cool air generated by the fan follows a fixed path, preventing airflow turbulence and thus improving heat dissipation efficiency; second, they draw in cooler air from outside the chassis, rather than the already heated air inside, which better lowers the CPU temperature. This design significantly improves heat dissipation, allowing the computer to maintain stable operation even under high loads.

[0041] Existing air guide covers are generally fixed to the fan with screws and self-riveting studs. During installation, special tools, such as Phillips screwdrivers or hex screwdrivers, are required to tighten the screws; moreover, users have to tighten multiple screws one by one, making the installation process complicated and causing great inconvenience to users' later maintenance and upgrade work.

[0042] To address this issue, this application modifies the connection method between the air guide shroud and the fan. Specifically, a locking mechanism is added to the air guide shroud. When the air guide shroud is rotated, the locking mechanism engages with the fan, thus achieving a fixed connection between the air guide shroud and the fan. Compared to traditional screw connections, this application allows for the installation and removal of the air guide shroud simply by screwing it on, eliminating the need for installation tools and individual screw tightening, thus simplifying the installation process and greatly facilitating future maintenance and upgrades for users. Furthermore, based on the structural characteristics of existing heat sinks, this application further refines the structure of the locking mechanism, eliminating the need for additional modifications to the heat sink structure and simplifying its design.

[0043] One embodiment of this application provides an air guide shroud, which is applied to electronic devices. By cooperating with the heat sink of the electronic device, it can effectively and promptly dissipate the heat generated by the electronic device, ensuring its normal and stable operation. The electronic device can be a high-performance, high-power electronic device such as a computer (e.g., desktop computer, server), network device (e.g., base station equipment), industrial electronic device (e.g., industrial control computer), consumer electronic device (e.g., projector), or medical electronic device (e.g., medical imaging equipment). The structure of the air guide shroud is described below using a desktop computer host as an example. Wherein, as... Figure 1 and Figure 2 As shown, the desktop computer host includes a chassis 400, a motherboard 300, and a heat sink 200; the chassis 400 has an air vent, the motherboard 300 is located inside the chassis 400, and the heat sink 200 is located on the motherboard 300 and faces the air vent.

[0044] like Figures 3 to 5 As shown, the air guide shroud 100 includes an air guide section 110 and a mounting section 120. The air guide section 110, as the air guide component of the air guide shroud 100, is generally cylindrical and has a first opening and a second opening. The first opening is close to the heat sink 200, and the second opening is away from the heat sink 200 and directly opposite the air outlet of the chassis 400. The shape of the first opening can be appropriately set according to the outer contour shape of the heat sink 200; for example, the outer contour of the heat sink 200 is as follows: Figure 2 If the shape is cylindrical, then the first opening is circular. The second opening can be a polygonal opening (e.g., a quadrilateral hole). Compared to a circular opening, a polygonal opening can increase the airflow area and improve the airflow efficiency of the heat sink 200.

[0045] In one embodiment, such as Figure 4 As shown, the internal contour of the air guide 110 is funnel-shaped, with the side closer to the mounting portion 120 being larger and the side farther away from the mounting portion 120 being smaller. The diameter of the first opening of the air guide 110 is smaller than the diameter of the second opening. By designing the internal contour of the air guide 110 as a funnel, the airflow channel can be gradually widened, reducing turbulence and resistance during airflow, making the airflow more stable and concentrated. This design not only improves the air delivery efficiency of the heat sink 200 but also guides the cooling air more precisely to the motherboard 300, thereby improving the heat dissipation effect. Furthermore, the funnel-shaped air guide 110 can also reduce the noise of the fan 220 during operation, improving the overall user experience of the electronic device 10.

[0046] The mounting part 120, as a mounting component of the air guide shroud 100, mainly serves to fix the air guide shroud 100 to the heat sink 200. For example... Figures 3 to 5As shown, the mounting part 120 is connected to the air guide part 110. A latch 121 is provided on the side of the mounting part 120 away from the air guide part 110. When the air guide cover 100 rotates around its own central axis M, the latch 121 can be engaged with the heat sink 200. During installation, rotating the air guide cover 100 will engage the latch 121 with the fan 220, thereby achieving a fixed connection between the air guide cover 100 and the fan 220.

[0047] As can be seen, the air guide cover 100 provided in this application embodiment has a latch 121 on the side of the mounting part 120 away from the air guide part 110. The latch 121 can be engaged with the heat sink 200 of the electronic device 10 when the air guide cover 100 rotates around its own central axis M. Compared with the traditional screw connection, this application can realize the installation and removal of the air guide cover 100 by simply turning the air guide cover 100. There is no need to use installation tools or turn screws one by one, which simplifies the installation steps and brings great convenience to the user's later maintenance and upgrade work.

[0048] Heat sink 200 is usually like Figure 2 As shown, the device includes a hollow base 210, a fan 220, and an outer ring 230. The hollow base 210 is mounted above the motherboard 300 and directly opposite the CPU mounting area of ​​the motherboard 300. The fan 220 is rotatably mounted on the hollow base 210, and the outer ring 230 surrounds the outer periphery of the fan 220. The outer periphery of the outer ring 230 has a protruding connecting portion 231, which is fixedly connected to the self-riveting stud 211 on the hollow base 210 via a threaded component 232 (e.g., a screw). Based on the structural characteristics of the heat sink 200, this application further defines the structure of the air guide shroud 100, specifically, as follows... Figure 4 and Figure 5 As shown, the latch 121 includes a latching groove 1211 and a receiving groove 1212. The opening of the receiving groove 1212 penetrates the end wall of the mounting portion 120 away from the air guide portion 110, and the opening of the latching groove 1211 penetrates the circumferential groove wall of the receiving groove 1212. When installing the air guide cover 100, first place the air guide cover 100 above the heat sink 200 and position the receiving groove 1212 of the air guide cover 100 facing the connecting portion 231 of the outer ring body 230; then as follows... Figure 7 As shown, press the air guide cover 100 downwards until the upper wall of the receiving groove 1212 (i.e., the groove wall of the receiving groove 1212 near the air guide portion 110) contacts the upper surface of the connecting portion 231 (i.e., the wall surface of the connecting portion 231 away from the main board 300) or the threaded part 232 on the connecting portion 231; finally, as shown Figure 8 As shown, rotate the air guide cover 100 clockwise or counterclockwise until the connecting part 231 is inserted into the fastening groove 1211 and locked in place. This completes the assembly of the air guide cover 100 onto the heat sink 200 (see Figure 1211). Figure 9 ).in, Figure 7 The dashed arrow in the image indicates the pressing direction of the air guide shroud 100. Figure 8 The dashed arrows in the diagram represent the rotation direction of the air guide shroud 100. This air guide shroud 100 structure requires no additional modifications to the structure of the heat sink 200. Installation of the air guide shroud 100 on the heat sink 200 is achieved simply by providing a receiving groove 1212 and a fastening groove 1211 in the mounting portion 120 of the air guide shroud 100, thus simplifying the structure of both the air guide shroud 100 and the heat sink 200.

[0049] Regarding the dimensions of the receiving groove 1212, namely its dimensions along the axial direction of the air guide shroud 100 and its dimensions along the circumferential direction of the air guide shroud 100, they can be set according to specific circumstances, as long as they can accommodate the connecting parts 231 on the heat sink 200 (e.g., Figure 2 The air guide cover 100 can be installed normally by avoiding the connecting part 231 on the outer ring 230, the self-riveting stud 211 on the hollow base 210 for connecting with the outer ring 230, and the mounting post 212 and self-locking screw 213 on the hollow base 210 for connecting with the main board 300.

[0050] The accommodating groove 1212 has a first distance between itself and the air guide portion 110 along the axial direction of the air guide cover 100, and the engaging groove 1211 has a second distance between itself and the air guide portion 110 along the axial direction of the air guide cover 100, wherein the second distance is greater than the first distance. With this configuration, when the air guide cover 100 is pressed down into place, the portion of the accommodating groove 1212 near the air guide portion 110 can avoid the head of the threaded part 232 on the connecting part 231, so that when the air guide cover 100 is screwed on, the connecting part 231 on the outer ring 230 can smoothly enter the engaging groove 1211 of the air guide cover 100. It can be understood that when the air guide cover 100 is pressed down, once the air guide cover 100 contacts the threaded part 232 on the connecting part 231, it is considered that the air guide cover 100 is pressed down into place. Of course, in some other embodiments, if the connecting part 231 is provided with a countersunk hole for accommodating the head of the threaded part 232 on the connecting part 231, then the groove wall of the accommodating groove 1212 near the air guide part 110 and the groove wall of the fastening groove 1211 near the air guide part 110 can be flush.

[0051] The fastening groove 1211 penetrates the sidewall of the mounting portion 120, both near and away from the central axis M of the air guide shroud 100. Furthermore, the width of the fastening groove 1211 along the axial direction of the air guide shroud 100 is equal to or slightly smaller than the thickness of the connecting portion 231 along the axial direction of the air guide shroud 100. This dimensional relationship between the fastening groove 1211 and the connecting portion 231 ensures a secure connection between the air guide shroud 100 and the heat sink 200. Wherein, as... Figure 6As shown, the opening of the fastening groove 1211 is provided with a flared section 1211a. The flared section 1211a makes it easier for the connecting part 231 to enter the fastening groove 1211, facilitating the assembly of the air guide shroud 100 and the heat sink 200. The diameter of the flared section 1211a gradually decreases along the direction from the opening to the bottom of the fastening groove 1211.

[0052] When the connecting portion 231 of the outer ring 230 extends into the fastening groove 1211, the fastening groove 1211 will be squeezed by the connecting portion 231, causing deformation of the part of the mounting portion 120 with the fastening groove 1211, which may lead to the risk of the mounting portion 120 breaking. Therefore, if... Figure 5 As shown, the air guide shroud 100 also includes a reinforcing portion 130 provided on the mounting portion 120. The reinforcing portion 130 extends along the axial direction of the air guide shroud 100 from one side of the mounting portion 120 to the other side and is close to the fastening groove 1211. The provision of the reinforcing portion 130 can increase the strength of the portion of the mounting portion 120 with the fastening groove 1211, prevent the fastening groove 1211 from failing, and ensure the firmness of the connection between the air guide shroud 100 and the heat sink 200.

[0053] The number of reinforcing parts 130 is the same as that of the fastening grooves 1211, and the two correspond one-to-one. The reinforcing parts 130 can be integrally formed with the air guide cover 100 by casting, injection molding or other methods.

[0054] like Figure 5 As shown, a wire passage 123 is also provided on the side of the mounting part 120 away from the air guide part 110, through which the wires of the heat sink 200 pass.

[0055] See you again Figure 2 The outer peripheral wall of the outer ring 230 is typically provided with multiple connecting portions 231, so that the outer ring 230 can be fixedly connected to the hollow base 210 by multiple threaded parts 232, thereby ensuring the connection strength of the outer ring 230 on the hollow base 210. In one embodiment, for example... Figure 5 As shown, multiple latches 121 are provided, and the openings of the latching grooves 1211 of all latches 121 face the same direction. By setting the openings of all latching grooves 1211 to face the same direction, when the air guide cover 100 is turned clockwise or counterclockwise, the latching groove 1211 of each latch 121 can engage with the corresponding connecting part 231, ensuring the smooth installation of the air guide cover 100. The number of latches 121 can be equal to or less than the number of connecting parts 231.

[0056] like Figure 7 As shown, the mounting part 120 can be annular and surround the outer periphery of the outer ring 230. This allows the first opening of the air guide part 110 to connect with the air outlet of the heat sink 200, enabling the airflow generated by the heat sink 200 to flow smoothly into the air guide part 110, thus facilitating heat dissipation of the equipment. For example, Figure 5 As shown, the side of the mounting part 120 away from the air guide part 110 has a non-grooved portion, and the non-grooved portion has a mounting guide slope 122. The mounting guide slope 122 facilitates the insertion of the mounting part 120 into the outer periphery of the outer ring body 230, and can guide the installation of the air guide cover 100, thus facilitating the installation of the air guide cover 100.

[0057] After the air guide cover 100 is pressed down into place, it needs to be screwed on in the preset direction so that the locking buckle 121 of the air guide cover 100 can be engaged with the connecting part 231 on the heat sink 200. To instruct the user to install the air guide cover 100 correctly, as follows: Figure 4 As shown, in one embodiment, the side of the air guide portion 110 away from the mounting portion 120 is provided with a flange 111, and the flange 111 has an installation mark 1111. The installation mark 1111 can instruct the user to rotate the air guide cover 100 in a preset direction (e.g., counterclockwise or clockwise) so that the air guide cover 100 is installed in place.

[0058] Regarding the number of installation markers 1111, there can be one, used solely to indicate the direction of installing the air guide shroud 100; or there can be two, with one indicating the direction of installing the air guide shroud 100 and the other indicating the direction of removing the air guide shroud 100; or both can be used to indicate the direction of installing the air guide shroud 100. Alternatively, there can be three or more installation markers 1111.

[0059] On the other hand, one embodiment of this application also provides an electronic device 10, such as... Figure 1 and Figure 2 As shown, the device includes a heat sink 200 and an air guide shroud 100 as described in any of the above-mentioned items. The outer peripheral wall of the heat sink 200 is provided with a connecting portion 231. The mounting portion 120 of the air guide shroud 100 is arranged around the outer peripheral side of the heat sink 200. When the air guide shroud 100 rotates around its own central axis M, the connecting portion 231 can enter the fastening groove 1211 of the air guide shroud 100 through the receiving groove 1212 of the air guide shroud 100 and be fastened and locked by the air guide shroud 100.

[0060] The electronic device 10 may include high-performance, high-power electronic devices such as computers (e.g., desktop computers, servers), network devices (e.g., base station equipment), industrial electronic devices (e.g., industrial control computers), consumer electronic devices (e.g., projectors), and medical electronic devices (e.g., medical imaging equipment).

[0061] The electronic device 10 provided in this application embodiment has a latch 121 on the side of the mounting portion 120 of the air guide 100 away from the air guide portion 110. The latch 121 can engage with the heat sink 200 of the electronic device 10 when the air guide 100 rotates around its own central axis M. Compared with the traditional screw connection, this application can realize the installation and removal of the air guide 100 by simply turning the air guide 100, without the need for installation tools or screwing in screws one by one, thus simplifying the installation process. This greatly facilitates the user's later maintenance and upgrade work. In addition, based on the structural characteristics of existing heat sinks, this application sets the latch 121 to include a receiving groove 1212 and a fastening groove 1211. There is no need to make additional improvements to the structure of the heat sink 200. The installation of the air guide 100 on the heat sink 200 can be achieved simply by opening the receiving groove 1212 and the fastening groove 1211 in the mounting part 120 of the air guide 100, which simplifies the structure of the air guide 100 and the heat sink 200.
