Description

Technical Field

[0001] The present application relates to the field of heat dissipation technology, and in particular to a computing device. Background Art

[0002] With the development of technology, the computing performance and functions of electronic products are constantly improving. The card slots in the server usually need to be able to support a variety of PCIE card configurations of different specifications. Common specifications of PCIE cards are full-height cards and half-height cards. Since the PCIE card slot needs to be compatible with full-height cards and half-height cards, the installation space in the server is reserved for full-height cards.

[0003] PCIE cards usually rely on the directional air flow formed by the fan in the server to flow through the heat-generating components on the surface of the card to dissipate heat. Since the height of the half-height card is lower than that of the full-height card, when the half-height card is installed in the card slot, there will be a cavity between the half-height card and the installation space of the card slot. When the server is working, due to the small airflow resistance of the cavity, the air flow will flow away from the cavity between the half-height card and the card slot, resulting in a small amount of air flowing through the half-height card and poor heat dissipation effect. Summary of the invention

[0004] An embodiment of the present application provides a computing device that can automatically adjust the direction of airflow according to the specifications of an inserted PCIE card, so that most of the airflow can flow through the PCIE card, thereby improving the heat dissipation effect of the PCIE card.

[0005] The embodiment of the present application provides a computing device for plugging in a PCIE card. When the PCIE card is plugged in the computing device, the thickness direction of the PCIE card is arranged along the height direction of the computing device. The computing device includes an air guide body, an air guide baffle and an elastic member. The air guide body includes a first side plate and a second side plate. The first side plate and the second side plate are arranged at an angle. The second side plate is connected to the first side plate. The first side plate and the second side plate are used to enclose a storage space. The first side plate has a ventilation hole, and the ventilation hole is connected to the storage space. The air guide baffle includes a shielding portion, which is located in the storage space and is rotatably connected to the air guide body. The elastic member includes a first end and a second end. The first end and the second end have an elastic force that moves away from each other. The first end elastically abuts on the shielding portion, and the second end elastically abuts on the second side plate. When the height of the inserted PCIE card is greater than a set value, the PCIE card abuts against the air guide baffle so that the shielding portion exposes the ventilation hole. When the height of the inserted PCIE card is less than or equal to the set value, the shielding portion blocks the ventilation hole.

[0006] It is understandable that the air guide baffle of the air guide assembly can rotate relative to the air guide body, so that the shielding portion of the air guide assembly can cover or expose the ventilation hole. When the shielding portion covers the ventilation hole, the airflow is blocked by the shielding portion and does not flow out of the ventilation hole, so that most of the airflow can flow to the surface of the PCIE card, thereby dissipating the heat of the PCIE card. When the ventilation hole is exposed relative to the shielding portion, the airflow can flow to the PCIE card through the ventilation hole, so that most of the airflow can flow to the surface of the PCIE card, thereby dissipating the heat of the PCIE card.

[0016] In a possible embodiment, the wind guide baffle also includes a supporting portion, which is located on a side of the shielding portion facing the ventilation hole, and one end of the supporting portion is connected to the shielding portion; when the shielding portion covers the ventilation hole, the supporting portion extends through the ventilation hole; when the shielding portion is away from the ventilation hole, the supporting portion is at least partially located in the accommodating space.

[0034] For ease of understanding, the terms involved in the embodiments of the present application are first explained.

[0035] Server: A server is a type of computer. It runs faster, has a higher load, and is more expensive than an ordinary computer. The server provides computing or application services to other clients in the network. The server has high-speed CPU computing power, long-term reliable operation, strong input / output (I / O) external data throughput capacity, and better scalability; generally speaking, the server has the ability to respond to service requests, provide services, and guarantee services. As a computing device, the internal structure of the server is very complex, with CPU, hard disk, memory, system, PCIE card, etc.

[0036] PCIE card: A card based on the high-speed serial computer expansion bus standard (Peripheral Component Interconnect Express, PCIE), also known as a PCI Express card or a PCIE-based card, refers to a network adapter with a PCIE interface, which is used as an expansion card interface in motherboard-level connections. Specifically, PCIE-based expansion cards are designed to be installed in PCIE-based slots in motherboards of devices such as hosts, servers, and network switches. PCIE cards come in a variety of sizes, and half-height, half-length (HHHL) and full-height, half-length (FHHL) are usually used to describe the physical size of PCI Express cards. For example, PCIE cards include half-height cards and full-height cards.

[0037] And / or: It is just a way to describe the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0038] Multiple: refers to two or more than two.

[0039] Connection: should be understood in a broad sense. For example, "connection" can be detachable or non-detachable; it can be direct or indirect through an intermediate medium. Among them, "fixed connection" can be connected to each other and the relative position relationship remains unchanged after connection. "Rotational connection" can be connected to each other and can rotate relative to each other after connection. "Sliding connection" can be connected to each other and can slide relative to each other after connection.

[0040] One-piece molding: "One-piece molding" means that in the process of forming one of the multiple components, the component is connected to the other components, and there is no need to connect the two components together through further processing (such as bonding, welding, snap connection, screw connection).

[0041] The directional terms mentioned in the embodiments of the present application, such as "bottom", "side", "inside", "outside", etc., are only directions referring to the drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application.

[0042] The specific embodiments of the present application will be clearly described below in conjunction with the accompanying drawings.

[0043] See also Figure 1 , Figure 1 It is a schematic diagram of the structure of the computing device 1000 provided in an embodiment of the present application.

[0044] The computing device 1000 includes a chassis 100, a card insertion device 200, and a heat sink 300. The card insertion device 200 and the heat sink 300 are both installed inside the chassis 100. The card insertion device 200 can be used to insert a PCIE card 400. The heat sink 300 can be located on one side of the card insertion device 200. For example, the heat sink 300 can be located on the air inlet side of the card insertion device 200, or on the side of the heat sink 300 away from the air inlet side. The heat sink 300 can also be located in the middle of the card insertion device 200. The relative position of the heat sink 300 and the card insertion device 200 is not specifically limited in this application.

[0045] The heat dissipation device 300 may include a fan (not shown). When the computing device 1000 is working, the devices on the surface of the PCIE card 400 generate heat, and the fan of the heat dissipation device 300 can form a directional airflow, and the airflow is blown toward the PCIE card 400 to take away the heat generated by the heat-generating devices on the PCIE card 400, thereby achieving heat dissipation of the PCIE card 400 and avoiding the situation where the PCIE card 400 cannot work normally due to excessive temperature. Exemplarily, the heat dissipation device 300 forms a directional airflow blowing toward the printed circuit board (PCB) provided on the PCIE card 400 to dissipate heat on the PCB side of the PCIE card 400.

[0046] Among them, the computing device 1000 can be, but is not limited to, a server, a router, a switch, a supercomputer, an AI (Artificial Intelligence) device, or an in-vehicle device, etc. The following will be described by taking the computing device 1000 as a server as an example, but it should be understood that it is not limited to this. The PCIE card has a variety of sizes. For example, the PCIE card 400 may include a first card 400a and a second card 400b. The width of the first card 400a is equivalent to the width of the second card 400b, and the length of the first card 400a is less than the length of the second card 400b. The first card 400a can be a half-height card, and the second card 400b can be a full-height card. The width of the half-height card is equivalent to the width of the full-height card, and the length of the half-height card is equivalent to half the length of the full-height card.

[0047] It should be noted that Figure 1 The purpose of the embodiment is only to schematically describe the connection relationship between the chassis 100, the card insertion device 200 and the heat dissipation device 300, and it does not specifically limit the connection position, specific structure and quantity of each device. The structure illustrated in the embodiment of the present application does not constitute a specific limitation on the computing device 1000. In other embodiments of the present application, the computing device 1000 may include Figure 1 More or fewer components may be shown, or some components may be combined or separated, or the components may be arranged differently. Figure 1 The components shown may be implemented in hardware, software or a combination of software and hardware.

[0048] See also Figure 2 , Figure 2 yes Figure 1 The structural diagram of the card insertion device 200 is shown.

[0049] The card insertion device 200 includes a base 21 and an air guide assembly 22. The base 21 has an installation space 210, which can be used to insert the PCIE card 400. The air guide assembly 22 is installed in the installation space 210 of the base 21. When the PCIE card 400 is plugged into the card insertion device 200, the air guide assembly 22 is at least partially located on the air inlet side of the PCIE card 400. For ease of explanation, the length direction of the base 21 is defined as the X-axis direction, the width direction of the base 21 is defined as the Y-axis direction, and the direction perpendicular to the X-axis direction and the Y-axis direction is defined as the Z-axis direction (that is, the thickness direction of the base 21). When the PCIE card 400 is plugged into the card insertion device 200, the thickness direction of the PCIE card 400 is set along the thickness direction (Z-axis direction) of the base 21.

[0050] In one embodiment, the card insertion device 200 is installed inside the chassis 100, and the height direction (Z-axis direction) of the card insertion device 200 is arranged along the height direction of the computing device 1000. When the PCIE card 400 is plugged into the card insertion device 200, the thickness direction of the PCIE card 400 is arranged along the height direction of the computing device 1000, that is, the PCIE card 400 is inserted into the card insertion device 200 in a horizontal manner. At this time, the Z-axis direction can be understood as the height direction of the computing device 1000, that is, the height direction of the chassis 100.

[0051] See also Figure 3 , Figure 3 yes Figure 2 A partially exploded schematic diagram of the base 21 is shown.

[0052] The base 21 includes a bottom wall 211, a first side wall 212, a second side wall 213, and a cover plate 214. The bottom wall 211, the first side wall 212, the second side wall 213, and the cover plate 214 are connected to form an installation space 210 of the base 21. The installation space 210 can accommodate PCIE cards 400 of various specifications, for example, the installation space 210 can accommodate a first card 400a and / or a second card 400b.

[0053] Exemplarily, the first side wall 212 can be installed on the bottom wall 211 along the X-axis direction and fixedly connected to the bottom wall 211. The second side wall 213 can be installed on the bottom wall 211 along the Y-axis direction and fixedly connected to the bottom wall 211. One end of the first side wall 212 is fixedly connected to one end of the second side wall 213.

[0054] Exemplarily, the cover plate 214 includes a first plate portion 2141 and a second plate portion 2142, and the first plate portion 2141 can be bent relative to the second plate portion 2142. Specifically, the first plate portion 2141 of the cover plate 214 can be vertically arranged relative to the second plate portion 2142. The first plate portion 2141 and the second plate portion 2142 of the cover plate 214 are respectively fixedly connected to the base. The first plate portion 2141 of the cover plate 214 can be fixed to the second side wall 213 of the base by fasteners (e.g., screws, etc.), and the second plate portion 2142 of the cover plate 214 can be fixed to the first side wall 212 of the base by fasteners (e.g., screws, etc.).

[0055] The base 21 may also include an interface 215, which is located in the installation space 210. Specifically, the interface 215 is fixed to the first side wall 212 for plugging with the PCIE card 400. The number of interfaces 215 may also be one or more. When the number of interfaces 215 is multiple, the multiple interfaces 215 may be arranged at intervals along the Z-axis direction. Exemplarily, the number of interfaces 215 may be three, namely, a first interface 215a, a second interface 215b, and a third interface 215c, and the first interface 215a, the second interface 215b, and the third interface 215c are arranged at intervals along the Z-axis direction.

[0056] The second side wall 213 may have a protrusion 216. The protrusion 216 extends along the negative direction of the X-axis and is used to fix the PCIE card 400. When the PCIE card 400 is inserted into the installation space 210 of the card insertion device 200 and plugged into the interface 215 of the first side wall 212, a fastener can be passed through the protrusion 216 and the PCIE card 400 to fix the PCIE card 400. Each interface 215 corresponds to at least one protrusion 216, and at least one protrusion 216 is arranged near the first side wall 212. Exemplarily, each interface 215 corresponds to two protrusions 216, and the two protrusions 216 are respectively arranged near the two ends of the second side wall 213 along the Y-axis direction. The second side wall 213 may also have a gap 217 extending along the Y-axis direction. The number of gaps 217 may be three, corresponding to three interfaces 215 respectively. The three gaps 217 are arranged at intervals along the Z-axis direction, and divide the second side wall 213 into a first side portion 213a, a second side portion 213b, and a third side portion 213c. The two protrusions 216 corresponding to the first interface 215a can be protruded from the first side portion 213a, and can be located at both ends of the corresponding gap 217. The two protrusions 216 corresponding to the second interface 215b can be protruded from the second side portion 213b, and can be located at both ends of the corresponding gap 217. The two protrusions 216 corresponding to the third interface 215c can be protruded from the third side portion 213c, and can be located at both ends of the corresponding gap 217. When the computing device 1000 is working, the heat generated by the PCIE card 400 can be dissipated from the gap 217, and the heat will not be accumulated in the installation space 210 of the card insertion device 200, thereby affecting the performance of the PCIE card 400.

[0057] Please also read Figure 4 and Figure 5 , Figure 4 yes Figure 3 The wind guide assembly 22 is shown as a schematic diagram of the structure at different angles.

The first main board 2211, the second main board 2212, the first side plate 2213 and the second side plate 2214 are connected to enclose a receiving space 220. Exemplarily, the first side plate 2213 and the second side plate 2214 of the first main board 2211 and the second main board 2212 can be integrally formed to reduce the preparation cost of the air guide body 221. In some other embodiments, the first side plate 2213 and the second side plate 2214 of the first main board 2211 and the second main board 2212 can also be assembled to form an integrated structure, and the present application does not impose specific restrictions on this.

The first side board 2213 and the second side board 2214 are arranged at an angle. For example, the first side board 2213 and the second side board 2214 can be arranged perpendicularly. It should be understood that the definitions of parallel and perpendicular are all for the current technological level, rather than being absolutely strict definitions in the mathematical sense, and a small amount of deviation is allowed, and it is possible to be approximately parallel or approximately perpendicular. For example, the first main board 2211 and the second main board 2212 are parallel, which means that the first main board 2211 and the second main board 2212 are parallel or approximately parallel, and the angle between the first main board 2211 and the second main board 2212 can be between 0° and 10°. For example, the first side panel 2213 and the second side panel 2214 are perpendicular to the first main board 2211, which means that the first side panel 2213 and the second side panel 2214 are perpendicular or approximately perpendicular to the first main board 2211, and the angle between the first side panel 2213 and the second side panel 2214 and the first main board 2211 can be between 80° and 100°.

The number of ventilation holes 2215 can be one or more, and the number of ventilation holes 2215 corresponds to the number of interfaces 215 of the base 21. When the number of ventilation holes 2215 is multiple, the multiple ventilation holes 2215 are arranged at intervals along the Z-axis direction. Exemplarily, the number of ventilation holes 2215 can be three, namely, the first ventilation hole 2215a, the second ventilation hole 2215b and the third ventilation hole 2215c. The first ventilation hole 2215a, the second ventilation hole 2215b and the third ventilation hole 2215c. They are arranged at intervals in sequence along the Z-axis direction.

[0061] In some possible embodiments, the air guide body 221 may further include a limiting portion 2216. The limiting portion 2216 is fixedly connected to the first side plate 2213 and the second side plate 2214. In the Z-axis direction, the limiting portion 2216 is located in the accommodating space 220 and between two adjacent ventilation holes 2215. The limiting portion 2216 has a first through hole 2217, and along the Z-axis direction, the first through hole 2217 passes through the limiting portion 2216. The first through hole 2217 is located on a side of the ventilation hole 2215 close to the second side plate 2214. The first through hole 2217 may be open-loop, and the opening of the first through hole 2217 may be toward the connection between the first side plate 2213 and the second side plate 2214.

[0062] The number of the limiting parts 2216 can be two, namely a first limiting part 2216a and a second limiting part 2216b, wherein the first limiting part 2216a is located between the first ventilation hole 2215a and the second ventilation hole 2215b, and the second limiting part 2216b is located between the second ventilation hole 2215b and the third ventilation hole 2215c.

[0063] The first main board 2211 and the second main board 2212 of the air guide body 221 may respectively have a second through hole 2218. The second through hole 2218 is in communication with the accommodation space 220, and the two second through holes 2218 and the first through hole 2217 are arranged at intervals along the Z-axis direction and are coaxially arranged.

[0064] The air guide body 221 also has a clamping portion 2219 for connecting with the cover plate 214 of the base 21. The clamping portion 2219 is located on the side of the first main board 2211 facing away from the second main board 2212, and is fixedly connected to the first main board 2211. Along the positive direction of the Z-axis direction, the clamping portion 2219 protrudes relative to the first main board 2211. Exemplarily, the clamping portion 2219 may include a first portion 2219a and a second portion 2219b. One end of the first portion 2219a is fixedly connected to the first main board 2211, and the other end is connected to the second portion 2219b. The projection area of ​​the second portion 2219b on the XY plane is larger than the projection area of ​​the first portion 2219a.

[0065] See also Figure 6 , Figure 6 yes Figure 4 The wind guide baffle 222 of the wind guide assembly 22 is shown as a schematic structural diagram at different angles.

[0066] The wind deflector 222 includes a shielding portion 2221, a supporting portion 2222 and a rotating portion 2223. The supporting portion 2222 is located on one side of the shielding portion 2221, and one end of the supporting portion 2222 is connected to the shielding portion 2221. The rotating portion 2223 is located on one end edge of the shielding portion 2221 and is connected to the shielding portion 2221. It can be understood that the wind deflector 222 can be an integral structural member, that is, the shielding portion 2221, the supporting portion 2222 and the rotating portion 2223 are integrally formed structural members. The wind deflector 222 can also be a spliced ​​structural member. For example, the shielding portion 2221, the supporting portion 2222 and the rotating portion 2223 can be formed into an integral structural member by splicing (such as mortise and tenon technology) or fixing (such as welding, bonding and other processes).

[0067] The number of the air guide baffles 222 may be one or more, and the number of the air guide baffles 222 corresponds to the number of the ventilation holes 2215. For example, the number of the air guide baffles 222 may be three, namely, the first air guide baffle 222a, the second air guide baffle 222b, and the third air guide baffle 222c, which are arranged in sequence along the Z-axis direction and correspond to the first ventilation hole 2215a, the second ventilation hole 2215b, and the third ventilation hole 2215c, respectively. Among them, the first shielding portion 2221a of the first air guide baffle 222a can be used to cover the first ventilation hole 2215a, the second air guide baffle 222b includes the second shielding portion 2221b which can be used to cover the second ventilation hole 2215b, and the third shielding portion 2221c of the third air guide baffle 222c can be used to cover the third ventilation hole 2215c, that is, the shielding portion 2221 of each air guide baffle 222 can be used to cover the corresponding ventilation hole 2215, so that the corresponding ventilation hole 2215 is in a closed state; the ventilation hole 2215 can also be in an open state, and the ventilation hole 2215 is exposed relative to the corresponding air guide baffle 222.

[0068] Exemplarily, the shielding portion 2221 of each wind deflector 222 may be connected to two rotating portions 2223. The two rotating portions 2223 are arranged at intervals along the Z-axis direction and are coaxially arranged. In the Z-axis direction, both ends of the two rotating portions 2223 that are arranged opposite to each other protrude relative to the shielding portion 2221. A side of the shielding portion 2221 connected to the rotating portion 2223 may have a notch 2225. Both ends of the two rotating portions 2223 that are arranged opposite to each other are located in the notch 2225. Exemplarily, the rotating portion 2223 may be cylindrical, which can be understood as a shaft.

[0069] In other embodiments, the shielding portion 2221 of each wind deflector 222 may also be connected to a rotating portion 2223. In the Z-axis direction, both ends of the rotating portion 2223 protrude relative to the shielding portion 2221, and a portion of the rotating portion 2223 is located in the notch 2225 of the shielding portion 2221.

[0070] The elastic member 223 is connected to the air guide baffle 222, and the elastic member 223 includes a first end 2231 and a second end 2232, and the first end 2231 and the second end 2232 are located on the side of the shielding portion 2221 facing away from the support portion 2222. Exemplarily, the elastic member 223 can be a torsion spring. The torsion spring can be sleeved between the two rotating portions 2223 and connect the two opposite ends of the two rotating portions 2223. The torsion spring is at least partially located in the notch 2225, and the first end 2231 and the second end 2232 of the torsion spring are located on the side of the shielding portion 2221 facing away from the support portion 2222. The number of the elastic member 223 can be three, respectively connected to the first air guide baffle 222a, the second air guide baffle 222b and the third air guide baffle 222c. It can be understood that by providing the notch 2225 in the shielding portion 2221, the notch 2225 can make way for the elastic member 223, which facilitates the assembly of the elastic member 223.

[0071] The support portion 2222 of each wind deflector 222 has a first side 2226 and a second side 2227 that are disposed opposite to each other, and a third side 2228 that connects the first side 2226 and the second side 2227. The third side 2228 connects the side of the shielding portion 2221 so that the first side 2226 and the side of the shielding portion 2221 form an angle. The first side 2226 and the third side 2228 form an obtuse angle, and the first side 2226 is closer to the rotating portion 2223 than the second side 2227. Exemplarily, the support portion 2222 may be trapezoidal, the third side 2228 is a hypotenuse, the first side 2226 is a short side of the trapezoid, and the second side 2227 is a long side of the trapezoid.

[0072] Exemplarily, each wind deflector 222 may further include a supporting portion 2224. The supporting portion 2224 is located at one end of the supporting portion 2222 away from the third side edge 2228 and is fixedly connected to the supporting portion 2222. The end surface area of ​​the supporting portion 2224 facing away from the supporting portion 2222 is larger than the end surface area of ​​the supporting portion 2222 connected to the supporting portion 2224. It can be understood that the supporting portion 2224 has a larger end surface area. When the supporting portion 2224 and the supporting portion 2222 are used to abut between the shielding portion 2221 and other components in the computing device 1000, the end surface of the supporting portion 2224 contacts the other components. Since the end surface area of ​​the supporting portion 2224 is larger, it is beneficial to improve the structural stability when the supporting portion 2224 and the supporting portion 2222 abut against other components in the computing device 1000. In other embodiments, the wind deflector 222 may not include the supporting portion 2224 , and the supporting portion 2222 may be used to directly support between the shielding portion 2221 and other components in the computing device 1000 .

[0073] Please also read Figures 4 to 6The wind guide baffle 222 is rotatably connected to the wind guide body 221, and the shielding portion 2221 of each wind guide baffle 222 corresponds to each ventilation hole 2215 one by one. The rotating portion 2223 is inserted into the wind guide body 221 and can rotate relative to the wind guide body 221. Exemplarily, at least part of the wind guide baffle 222 can be located in the accommodating space 220 of the wind guide body 221. One end of the rotating portion 2223 of the wind guide baffle 222 protruding from the shielding portion 2221 can be inserted into the first through hole 2217 or the second through hole 2218 of the wind guide body 221, and can rotate relative to the first through hole 2217 or the second through hole 2218. The shielding portion 2221 of each wind guide baffle 222 rotates relative to the corresponding ventilation hole 2215 to shield or avoid the corresponding ventilation hole 2215. The shielding portion 2221 is arranged at an angle with the first side plate 2213 of the wind guide body 221. Exemplarily, the angle between the shielding portion 2221 and the first side plate 2213 may range from 30° to 90°, for example, may be 45°, 60°, 75°, 90°, etc.

[0074] When the wind guide baffle 222 is connected to the wind guide body 221, along the Z-axis direction, the shielding portion 2221 of the first wind guide baffle 222a is located between the second main board 2212 and the first limiting portion 2216a, and one rotating portion 2223 of the first wind guide baffle 222a is inserted in the first through hole 2217, and the other rotating portion 2223 is inserted in the second through hole 2218; the second wind guide baffle 222b is located between the first limiting portion 2216a and the second limiting portion 2216b, and the two rotating portions 2223 of the second wind guide baffle 222b are both inserted in the first through hole 2217; the third wind guide baffle 222c is located between the second limiting portion 2216b and the first main board 2211, and one rotating portion 2223 of the third wind guide baffle 222c is inserted in the first through hole 2217, and the other rotating portion 2223 is inserted in the second through hole 2218. It can be understood that when the rotating portion 2223 of the air guide baffle 222 is inserted into the first through hole 2217 or the second through hole 2218 of the air guide body 221, the first main board 2211, the second main board 2212 and the limiting portion 2216 of the air guide body 221 can limit the movement of the air guide baffle 222 in the Z-axis direction. Exemplarily, the first end 2231 and the second end 2232 of each elastic member 223 are both located on the side of the shielding portion 2221 of the air guide baffle 222 facing away from the ventilation hole 2215 of the air guide body 221.

[0075] When the vent 2215 is in a closed state, the elastic member 223 is in a compressed state, and the first end 2231 and the second end 2232 of the elastic member 223 have an elastic force that moves away from each other. The first end 2231 of each elastic member 223 elastically abuts against the shielding portion 2221 of the corresponding wind guide baffle 222, and the second end 2232 elastically abuts against the position on the second side plate 2214 of the wind guide body 221 that is opposite to the shielding portion 2221. The elastic force of the second side plate elastic member 223 has a force from the second side plate 2214 toward the first side plate 2213 on the shielding portion 2221, so that the shielding portion 2221 can be abutted against the first side plate 2213 of the wind guide body 221 and cover the corresponding vent 2215. At this time, the support portion 2222 of the wind guide baffle 222 extends out of the accommodating space 220 of the wind guide body 221 through the vent 2215. The shielding portion 2221 can rotate toward the second side plate 2214 to expose the ventilation hole 2215 and squeeze the first end 2231 toward the second end 2232. At this time, the supporting portion 2222 of the air guide baffle 222 at least partially extends into the accommodating space 220 of the air guide body 221 through the ventilation hole 2215.

[0076] It can be understood that the elastic member 223 is in a compressed state, the first end 2231 of the elastic member 223 elastically abuts against the shielding portion 2221 of the air guide baffle 222, and the second end 2232 of the elastic member 223 elastically abuts against the second side plate 2214 of the air guide body 221, so that the shielding portion 2221 can continue to cover the corresponding ventilation hole 2215, and when the computing device 1000 is being transported, the air guide baffle 222 will not rotate relative to the air guide body 221; even under the blowing of the internal directional airflow of the computing device 1000, the air guide baffle 222 will not shake, thereby avoiding interference or collision between the air guide baffle 222 and other components in the computing device 1000, thereby affecting the normal use of the computing device 1000.

[0077] In other embodiments, the elastic member 223 may also be other elastic structural members that can hold the shielding portion 2221 between the first side plates 2213 of the air guide body 221 .

[0078] See also Figure 7 , Figure 7 yes Figure 3 An application scenario diagram of the card insertion device 200 is shown.

[0079] The air guide assembly 22 is located in the installation space 210 of the base 21 and is snap-fitted with the base 21. Exemplarily, the first plate portion 2141 of the cover plate 214 of the base 21 has a groove 2143. The groove 2143 has an opening 2144 at the edge of the first plate portion 2141 of the cover plate 214 away from the second plate portion 2142. A slide groove 2145 is provided in the groove 2143, and the slide groove 2145 is connected to the opening 2144 of the groove 2143, and the slide groove 2145 can penetrate the first plate portion 2141 of the cover plate 214 in the Z-axis direction. The first part 2219a of the snap-fitting part 2219 of the air guide assembly 22 can slide into the slide groove 2145 through the opening 2144, and the second part 2219b of the snap-fitting part 2219 can be located in the groove 2143. It can be understood that the slide groove 2145 can limit the movement of the air guide assembly 22 relative to the base 21 in the X-axis direction, and the second part 2219b of the clamping portion 2219 and the first main board 2211 of the air guide assembly 22 can limit the movement of the air guide assembly 22 relative to the base 21 in the Z-axis direction.

[0080] In one embodiment, the second mainboard 2212 of the air guide assembly 22 may be supported on the bottom wall 211 of the base 21. On the one hand, it is beneficial to improve the stability of the connection between the air guide assembly 22 and the base 21; on the other hand, there may be no gap between the air guide assembly 22 and the base 21 in the Z-axis direction, and the airflow used for heat dissipation in the computing device 1000 will not flow out from the gap between the air guide assembly 22 and the base 21, reducing the loss of airflow, thereby facilitating more airflow for heat dissipation of the PCIE card 400 and improving heat dissipation efficiency.

[0081] In other embodiments, the card insertion device 200 can also fix the air guide assembly 22 to the base 21 by fasteners (e.g., screws, etc.). For example, the fasteners can pass through the cover plate 214 of the base 21 and the air guide body 221 of the air guide assembly 22, or the fasteners can pass through the bottom wall 211 of the base 21 and the air guide body 221 of the air guide assembly 22 to fix the connection between the air guide assembly 22 and the base 21.

[0082] The air guide assembly 22 is installed in the installation space 210 of the base 21 and is arranged near the air inlet side of the base 21 of the card insertion device 200. It can be understood that the heat dissipation device 300 can be located on the air inlet side of the air guide assembly 22 of the card insertion device 200. The installation space 210 of the base 21 is located at a part of the air guide assembly 22 away from the air inlet side to form a card slot 2101. Specifically, the first side plate 2213 of the air guide assembly 22 is opposite to and spaced from the second side wall 213 of the base 21. Along the X-axis direction, the space between the first side plate 2213 and the second side wall 213 of the air guide body 221 of the air guide assembly 22 can accommodate the insertion of a PCIE card 400, and the space extends along the Y-axis direction to form a plurality of card slots 2101 of the card insertion device 200, and the plurality of card slots 2101 are used to plug in a plurality of PCIE cards 400. Among them, the first card slot 2101a is between the first side portion 213a and the first ventilation hole 2215a, and the first interface 215a is located in the first card slot 2101a; the second card slot 2101b is between the second side portion 213b and the second ventilation hole 2215b, and the second interface 215b is located in the second card slot 2101b; the third card slot 2101c is between the third side portion 213c and the third ventilation hole 2215c, and the third interface 215c is located in the third card slot 2101c.

[0083] It can be understood that the length of the first card 400a (i.e., the half-height card) is equivalent to half of the length of the card slot 2101 in the Y-axis direction, and the width of the first card 400a (i.e., the half-height card) is equivalent to the length of the card slot 2101 in the X-axis direction. The length of the second card 400b is equivalent to the length of the card slot 2101 in the Y-axis direction, and the width of the second card 400b is equivalent to the length of the card slot 2101 in the X-axis direction. The air guide component 22 is spaced apart from the first side wall 212 of the base 21. Specifically, when the PCIE card 400 is plugged into the interface 215 of the base 21, in the Y-axis direction, the air guide component 22 can be arranged opposite to the protruding portion of the second card 400b relative to the first card 400a.

[0084] It can be understood that in this embodiment, the height direction (Z-axis direction) of the card insertion device 200 is set along the height direction (i.e., the gravity direction) of the computing device 1000, that is, the plurality of ventilation holes 2215 are arranged at intervals along the height direction (i.e., the gravity direction) of the computing device 1000. At this time, the rotation direction of the shielding portion 2221 is perpendicular to the gravity direction, and the shielding portion 2221 cannot continue to cover the corresponding ventilation holes 2215 under the action of gravity. In the embodiment of the present application, an elastic member 223 is provided, and the first end 2231 of the elastic member 223 elastically abuts against the shielding portion 2221 of the air guide baffle 222, and the second end 2232 of the elastic member 223 elastically abuts against the second side plate 2214 of the air guide body 221, so that the shielding portion 2221 can continuously cover the corresponding ventilation hole 2215 under the action of the elastic force of the elastic member 223, and the air guide baffle 222 will not rotate relative to the air guide body 221 during the transportation of the computing device 1000; even under the blowing of the internal directional airflow of the computing device 1000, the air guide baffle 222 will not shake, thereby preventing the air guide baffle 222 from interfering with or colliding with other components in the computing device 1000 and affecting the normal use of the computing device 1000. On the other hand, even if the height direction (Z-axis direction) of the card insertion device 200 is arranged perpendicularly to the height direction (i.e., the gravity direction) of the computing device 1000, when the thickness direction of the PCIE card 400 is arranged perpendicularly to the height direction of the computing device 1000, that is, when the PCIE card 400 is inserted into the card insertion device 200 in a vertical manner, the embodiment of the present application can also enable the shielding portion 2221 to cover the corresponding ventilation hole 2215 more continuously and stably under the action of the elastic force of the elastic member 223 by setting the elastic member 223.

[0085] See also Figure 7 and Figure 8 , Figure 8 yes Figure 7 The PCIE card 400 is located in the card slot 2101 of the base 21 and is plugged into the interface 215 of the base 21 . Figure 7 The PCIE cards 400 inserted in the illustrated card insertion device 200 are all first cards 400a, that is, the first card slot 2101a, the second card slot 2101b, and the third card slot 2101c are all inserted with half-height cards.

[0086] In the Y-axis direction, the card slot 2101 includes a first space 2102 and a second space 2103 . Figure 8The first space 2102 and the second space 2103 are schematically distinguished by a dotted line. The first space 2102 of the card slot 2101 is connected to the second space 2103. The first space 2102 is located on the side of the second space 2103 close to the first side wall 212 of the base 21. The first card 400a occupies the first space 2102 of the card slot 2101, while the second space 2103 of the card slot 2101 is not occupied. Under the action of the elastic force of the elastic member 223, the shielding portion 2221 of the air guide assembly 22 covers the ventilation hole 2215, and the supporting portion 2222 extends out of the accommodating space 220 of the air guide body 221 through the ventilation hole 2215 and extends into the second space 2103 of the card slot 2101. It can be understood that the supporting portion 2222 can be used to support the shielding portion 2221 to keep the shielding portion 2221 away from the ventilation hole 2215. It can be understood that when the height of the inserted PCIE card 400 is less than or equal to the set value (half the length of the card slot 2101 in the Y-axis direction), the PCIE card 400 occupies the first space 2102, and the shielding portion 2221 shields the ventilation hole 2215. At this time, the ventilation hole 2215 is in a closed state. When the airflow is blown toward the card insertion device 200, the airflow is blocked by the shielding portion 2221 and does not flow out of the ventilation hole 2215, so that most of the airflow can flow to the surface of the first card 400a, thereby dissipating the heat of the first card 400a.

[0087] Taking the first card slot 2101a as an example, when the first card 400a is plugged into the first interface 215a of the base 21, in the Y-axis direction, the first card 400a only occupies the first space 2102 of the first card slot 2101a of the base 21, and the first ventilation hole 2215a is connected to the second space 2103 of the first card slot 2101a of the base 21. The supporting portion 2222 of the first air guide baffle 222a extends into the second space 2103 of the first card slot 2101a not occupied by the first card 400a through the first ventilation hole 2215a, and the first shielding portion 2221a covers the first ventilation hole 2215a.

[0088] It can be understood that when the first card 400a is inserted into the card slot 2101 of the base 21 along the Y-axis direction, the first card 400a will first contact the supporting portion 2224 of the air guide assembly 22. When the first card 400a continues to be pushed and the external force is greater than the elastic force of the elastic member 223, the air guide baffle 222 will further compress the elastic member 223 under the push of the first card 400a and rotate relative to the air guide body 221. Under the action of external force, the shielding portion 2221 rotates from the first side plate 2213 to the second side plate 2214; then the first card 400a continues to be pushed until the first card 400a is plugged into the interface 215, and the first card 400a is offset from the ventilation hole 2215 in the Y-axis direction. The first card 400a is no longer in contact with the supporting portion 2224 of the air guide assembly 22, and under the action of the elastic force of the elastic member 223, the shielding portion 2221 rotates relative to the air guide body 221 along the second side plate 2214 of the air guide body 221 toward the first side plate 2213 of the air guide body 221, thereby covering the ventilation hole 2215.

[0089] It is understandable that when the PCIE card 400 inserted in the computing device 1000 is the first card 400a, in the Y-axis direction, the first card 400a only occupies the first space 2102 of the card slot 2101. When the airflow is blown toward the card insertion device 200, since the airflow resistance of the second space 2103 not occupied by the first card 400a is small, the airflow will flow out from the second space 2103 of the card slot 2101, thereby reducing the air volume flowing through the first card 400a and causing the first card 400a to have a poor heat dissipation effect. However, the present application sets an air guide assembly 22 between the heat dissipation device 300 and the first card 400a, and the shielding portion 2221 of the air guide assembly 22 can cover the ventilation hole 2215. In this way, when the heat dissipation device blows the air flow toward the card insertion device 200, the air flow flowing into the air guide component 22 will be blocked by the shielding portion 2221, and the air flow will not flow out from the second space 2103 of the card slot 2101 through the ventilation hole 2215. Most of the air flow can flow through the surface of the first card 400a, thereby improving the heat dissipation effect of the first card 400a.

[0090] See also Fig. 9 and Fig.10 , Fig. 9 yes Figure 3 Another application scenario diagram of the card insertion device 200 is shown. Fig.10 yes Fig. 9 The illustrated schematic diagram is a partial cross-section of the card insertion device 200 at line BB.

[0091] Fig. 9 The PCIE cards 400 inserted in the illustrated card insertion device 200 are all second cards 400b, that is, the first card slot 2101a, the second card slot 2101b, and the third card slot 2101c are all inserted with full-height cards.

[0092] In the Y-axis direction, the second card 400b occupies the card slot 2101 and contacts the abutting portion 2224 of the air guide assembly 22. The supporting portion 2222 and the abutting portion 2224 abut between the second card 400b and the shielding portion 2221 and extend into the accommodating space 220 of the air guide body 221, so that the shielding portion 2221 no longer covers the ventilation hole 2215, that is, the ventilation hole 2215 is in an open state. The second card 400b can be exposed relative to the ventilation hole 2215. It can be understood that when the height of the inserted PCIE card 400 is greater than the set value (half the length of the card slot 2101 in the Y-axis direction), the PCIE card 400 occupies the first space 2102 and the second space 2103 ( Fig. 9 The first space 2102 and the second space 2103 are schematically distinguished by dotted lines in the figure, and the PCIE card 400 abuts against the air guide baffle 222, so that the shielding portion 2221 exposes the ventilation hole 2215. When the airflow is blown toward the card insertion device 200, the airflow flows toward the second card 400b through the ventilation hole 2215, so that most of the airflow can flow toward the surface of the second card 400b, thereby dissipating the heat of the second card 400b.

[0093] Taking the first card slot 2101a as an example, when the second card 400b is plugged into the first interface 215a of the base 21, in the Y-axis direction, the second card 400b occupies the first card slot 2101a of the base 21, the second card 400b is exposed relative to the first ventilation hole 2215a, and contacts the supporting portion 2224 of the air guide component 22, the supporting portion 2222 and the supporting portion 2224 are supported between the second card 400b and the shielding portion 2221, and extend into the accommodating space 220 of the air guide body 221, and the first ventilation hole 2215a is exposed relative to the first shielding portion 2221a.

[0094] The shielding portion 2221 may be disposed at an angle θ with the first side plate 2213 of the air guide body 221. Exemplarily, the angle θ may range from 30° to 90°, for example, the angle θ may be 45°, 60°, 75°, 90°, etc.

[0095] When the second card 400b is inserted into the card slot 2101 of the base 21 along the Y-axis direction, the second card 400b first contacts the abutting portion 2224 of the air guide assembly 22, and continues to push the second card 400b. When the external force is greater than the elastic force of the elastic member 223, the air guide baffle 222 will further compress the elastic member 223 under the push of the second card 400b, and rotate relative to the air guide body 221. Under the action of the external force, the shielding portion 2221 rotates from the first side plate 2213 to the second side plate 2214, and no longer covers the ventilation hole 2215. When the airflow is blown toward the card insertion device 200, the airflow flowing into the air guide assembly 22 can flow to the surface of the second card 400b through the ventilation hole 2215, so that the second card 400b can be cooled.

[0096] After the second card 400b is pulled out from the base 21, the shielding portion 2221 of the air guide assembly 22 rotates relative to the air guide body 221 along the second side plate 2214 of the air guide body 221 toward the first side plate 2213 of the air guide body 221 under the elastic force of the elastic member 223, until it abuts against the first side plate 2213 of the air guide body 221 to cover the ventilation hole 2215. It can be understood that when the second card 400b is inserted into the card insertion device 200 provided in this embodiment, the ventilation hole 2215 can be automatically opened so that air can flow to the second card 400b through the ventilation hole 2215, and after the second card 400b is pulled out, the ventilation hole 2215 can be automatically closed.

[0097] In one embodiment, the card insertion device 200 can be used to simultaneously insert the first card 400a and the second card 400b. For example, the first card slot 2101a of the card insertion device 200 can be used to insert the first card 400a, and the second card slot 2101b can be used to insert the second card 400b. At this time, the shielding portion 2221 of the first air guide baffle 222a covers the first ventilation hole 2215a under the elastic force of the elastic member 223, that is, the first ventilation hole 2215a is in a closed state. When the airflow is blown toward the card insertion device 200, most of the airflow can flow through the surface of the first card 400a, and the heat dissipation effect of the first card 400a is better. The shielding portion 2221 of the second air guide baffle 222b no longer covers the second ventilation hole 2215b under the support of the support portion 2222, and the second ventilation hole 2215b is exposed relative to the shielding portion 2221 of the second air guide baffle 222b, that is, the second ventilation hole 2215b is in an open state. When the airflow is blown toward the card insertion device 200, the airflow can flow toward the second card 400b through the second ventilation hole 2215b, and the heat dissipation effect of the second card 400b is better.

[0098] See also Fig.11 , Fig.11 yes Figure 3 A schematic structural diagram of another air guide assembly 22 is shown.

[0099] The wind guide assembly 22 includes a wind guide body 221 and a wind guide baffle 222. The structure and arrangement of the wind guide body 221 and the wind guide baffle 222 and the connection between the wind guide body 221 and the wind guide baffle 222 can refer to the relevant description of the wind guide body 221 and the wind guide baffle 222 in any of the above embodiments, and will not be described in detail here. The difference of this embodiment is that the wind guide assembly 22 of this embodiment does not include the elastic member 223.

[0100] The included angle between the shielding portion 2221 of the air guide baffle 222 and the first side plate 2213 of the air guide body 221 is an acute angle, for example, the included angle may be 30°, 45°, 60°, etc. The shielding portion 2221 may rotate relative to the air guide body 221 under the action of airflow and / or gravity to cover the ventilation hole 2215.

[0101] For example, the air guide baffle 222 may be a light, thin plate-shaped structure. In this way, the air guide baffle 222 may rotate relative to the air guide body 221 under the drive of the directional air flow, and the shielding portion 2221 of the air guide baffle 222 may cover the corresponding ventilation hole 2215, and under the pressure of the directional air flow, the corresponding ventilation hole 2215 may be continuously covered, so that the corresponding ventilation hole 2215 is in a continuously closed state.

[0102] When the card insertion device 200 is not plugged into the PCIE card 400 or is plugged into the first card 400a, the shielding portion 2221 of the air guide baffle 222 can cover the corresponding ventilation hole 2215 under the action of the directional air flow, so that most of the air flow can flow through the surface of the first card 400a, and the heat dissipation effect of the first card 400a is better. When the card insertion device 200 is plugged into the second card 400b, the second card 400b can resist the air guide baffle 222, so that the ventilation hole 2215 can be exposed relative to the corresponding shielding portion 2221, and the air flow can flow to the surface of the second card 400b through the ventilation hole 2215, and the heat dissipation effect of the second card 400b is better.
