Technical Field
[0001] This utility model relates to the field of chassis technology, and in particular to a 2U chassis structure with a full-height, double-width graphics card. Background Technology
[0002] With the rapid development of chip technology, mainstream graphics cards have emerged in the form of full-height, double-width graphics cards. When installing ATX, EATX, or CEB motherboards in existing 2U non-heat-resistant server configurations, full-height, double-width graphics cards cannot be installed due to the limited internal space of the chassis.
[0003] Currently, the height of the chassis can be increased by replacing it with a 3U or 4U chassis to accommodate full-height, double-width graphics cards, but this increases the overall cost of the server. Alternatively, without changing the chassis type, a PCIe adapter card can be used to specify the third PCIe slot on the motherboard, changing the graphics card's installation orientation. However, due to the wide variety of motherboards and their inconsistent PCIe slot layouts, if the specified slot is not the required size, the chassis cannot accommodate a full-height, double-width graphics card, requiring a chassis redesign. This necessitates a high degree of chassis compatibility due to the diverse motherboard types.
[0004] In summary, when using a PCIe adapter card with different types of motherboards in a 2U chassis, the motherboard slot specifications are strictly required. Otherwise, it cannot flexibly adapt to various motherboards and cannot meet the requirements for installing full-height, double-width graphics cards. Utility Model Content
[0005] The technical problem this utility model aims to solve is that when existing 2U chassis are configured with different types of motherboards, the use of PCIe adapter cards has strict requirements on the motherboard slot specifications; otherwise, it is impossible to flexibly adapt to various motherboards and it is difficult to meet the requirements for installing full-height, double-width graphics cards.
[0006] To solve the above-mentioned technical problems, this utility model provides a technical solution for a 2U chassis structure with a full-height, double-width graphics card: The 2U chassis structure with a full-height dual-width graphics card includes a chassis body, and a motherboard, fan assembly, full-height dual-width graphics card, graphics card bracket, flexible cable and flexible cable bracket disposed in the chassis body. The chassis body includes a rear panel, and the fan assembly and the rear panel are distributed at intervals along the length of the chassis body. The graphics card bracket is located on the side of the fan assembly near the rear window panel of the chassis. The motherboard and the full-height dual-width graphics card are both installed between the graphics card bracket and the rear window panel of the chassis. The graphics card bracket has ventilation holes that connect the fan assembly and the full-height dual-width graphics card. The flexible flat cable bracket is fixedly connected to the fan assembly and the rear window panel of the chassis, and the flexible flat cable bracket is distributed parallel to and spaced apart from the full-height dual-width graphics card. The flexible flat cable is installed on the flexible flat cable bracket, and the flexible flat cable is electrically connected to the PCIe slot of the motherboard and the connector of the full-height dual-width graphics card.
[0007] Furthermore, the graphics card bracket includes an air guide shroud. Along the direction away from the fan assembly, the air guide shroud has a flared opening with a smaller opening. The flared opening corresponds to the fan assembly, and the ventilation hole is located on the side of the air guide shroud away from the fan assembly.
[0008] Furthermore, the air guide shroud is provided with a first fixing hole on the side away from the fan assembly. The first fixing hole is spaced apart from the ventilation hole, and a first screw is connected between the first fixing hole and the full-height double-width graphics card.
[0009] Furthermore, the rear window panel of the chassis has a rear window slot, and the full-height dual-width graphics card has a full-height baffle on the side near the rear window panel of the chassis. The full-height baffle is inserted into the rear window slot, and the full-height baffle is fixedly connected to the rear window panel of the chassis by a second screw.
[0010] Furthermore, the air guide shroud has a first baffle on the side away from the fan assembly, the first baffle has a first hole, the graphics card bracket also includes a base, the upper part of the base has a second baffle, the second baffle has a second hole, the first baffle and the second baffle are arranged parallel to each other, and a third screw passes through the first hole and the second hole.
[0011] Furthermore, along the height direction of the chassis body, the motherboard and the full-height, double-width graphics card are spaced apart and form a heat dissipation channel. The base has a first heat dissipation hole, and the rear window panel of the chassis has a second heat dissipation hole. The second heat dissipation hole is spaced apart from the rear window slot, and the first heat dissipation hole and the second heat dissipation hole are respectively connected to the heat dissipation channel.
[0012] Furthermore, the flexible flat cable is arranged in a zigzag shape within the heat dissipation channel, and one end of the flexible flat cable is fixed to the flexible flat cable bracket and electrically connected to the plug of the full-height double-width graphics card.
[0013] Furthermore, one end of the flexible flat cable is provided with a first slot, and the other end of the flexible flat cable is provided with a first plug. The first slot is fixedly installed on the flexible flat cable bracket, and the first plug is electrically connected to the PCIe slot of the motherboard.
[0014] Furthermore, along the width direction of the chassis body, the first slot is connected to the connector of the full-height dual-width graphics card; along the height direction of the chassis body, the first connector is connected to the PCIe slot of the motherboard.
[0015] Compared with existing technologies, the 2U chassis structure with a full-height, double-width graphics card of this utility model has the following advantages: This 2U chassis structure with a full-height, double-width graphics card adopts a design consisting of a chassis body, motherboard, fan assembly, full-height, double-width graphics card, graphics card bracket, flexible cable, and flexible cable bracket. The motherboard and full-height, double-width graphics card are both installed between the graphics card bracket and the rear panel of the chassis. The ventilation holes of the graphics card bracket connect the fan assembly and the full-height, double-width graphics card, providing a reliable support structure for the graphics card and ensuring its positional stability in a horizontal position. By centrally arranging the motherboard and full-height, double-width graphics card near the rear panel of the chassis, the ventilation hole design of the graphics card bracket allows the airflow generated by the fan assembly to directly and efficiently pass over the full-height, double-width graphics card, achieving optimal space utilization and heat dissipation efficiency.
[0016] The flexible flat cable bracket is fixedly connected to the fan assembly and the rear panel of the chassis. It is arranged parallel to and spaced apart from the full-height, double-width graphics card. The flexible flat cable is mounted on the bracket and can be freely bent and folded, allowing for adaptation to various motherboards by adjusting its routing path. The bracket provides a standardized and repeatable installation method for the flexible flat cable, ensuring it always stays on a preset safe path. This avoids damage caused by careless handling during manual cabling and prevents excessive bending, shaking, or scratches from other components.
[0017] The flexible flat cable connects to the motherboard's PCIe slot and the connector of the full-height dual-width graphics card, ensuring stable and reliable signal transmission between the motherboard and the full-height dual-width graphics card. It is precisely because of the flexible electrical connection function of the flat cable that the 2U chassis is no longer strictly dependent on a specific motherboard specification. It can flexibly adapt to the PCIe slot positions of different motherboards, while reliably installing graphics cards and providing good heat dissipation for full-height dual-width graphics cards, thus improving the compatibility and versatility of the 2U chassis.

[0023] like Figures 1 to 4As shown, an embodiment of the present invention provides a 2U chassis structure with a full-height dual-width graphics card, including a chassis body 1, and a motherboard 2, a fan assembly 3, a full-height dual-width graphics card 4, a graphics card bracket 5, a flexible cable 6, and a flexible cable bracket 7 disposed within the chassis body 1. The chassis body 1 includes a rear window panel 10, and the fan assembly 3 and the rear window panel 10 are spaced apart along the length of the chassis body 1.
[0024] The graphics card bracket 5 is located on the side of the fan assembly 3 near the rear window panel 10 of the chassis. The motherboard 2 and the full-height dual-width graphics card 4 are both installed between the graphics card bracket 5 and the rear window panel 10 of the chassis. The graphics card bracket 5 has ventilation holes 50, which connect the fan assembly 3 and the full-height dual-width graphics card 4. The flexible cable bracket 7 is fixedly connected to the fan assembly 3 and the rear window panel 10 of the chassis. The flexible cable bracket 7 and the full-height dual-width graphics card 4 are distributed parallel to each other. The flexible cable 6 is installed on the flexible cable bracket 7 and is electrically connected to the PCIe slot 20 of the motherboard 2 and the plug of the full-height dual-width graphics card 4, respectively.
[0025] This 2U chassis with a full-height, dual-width graphics card features a chassis body (1), motherboard (2), fan assembly (3), full-height, dual-width graphics card (4), graphics card bracket (5), flexible cable (6), and flexible cable bracket (7). The motherboard (2) and full-height, dual-width graphics card (4) are both mounted between the graphics card bracket (5) and the rear panel (10). The ventilation holes (50) of the graphics card bracket (5) connect the fan assembly (3) and the full-height, dual-width graphics card (4), providing a reliable support structure and ensuring its positional stability in a horizontal configuration. By centrally arranging the motherboard (2) and full-height, dual-width graphics card (4) near the rear panel (10), the ventilation holes (50) of the graphics card bracket (5) allow the airflow generated by the fan assembly (3) to directly and efficiently pass over the full-height, dual-width graphics card (4), optimizing space utilization and heat dissipation efficiency.
[0026] The flexible flat cable bracket 7 is fixedly connected to the fan assembly 3 and the rear window panel 10 of the chassis. The bracket 7 is arranged parallel to and spaced apart from the full-height, double-width graphics card 4. The flexible flat cable 6 is installed on the bracket 7. The flexible flat cable 6 can be freely bent and folded, and its routing path can be adjusted to adapt to various motherboards 2. The bracket 7 provides a standardized and repeatable installation method for the flexible flat cable 6, ensuring it always stays on a preset safe path, avoiding damage caused by careless handling during manual wiring, and preventing excessive bending, shaking, or scratches from other components.
[0027] The flexible flat cable 6 is electrically connected to the PCIe slot 20 of the motherboard 2 and the connector of the full-height dual-width graphics card 4, ensuring stable and reliable signal transmission between the motherboard 2 and the full-height dual-width graphics card 4. It is precisely because the flexible flat cable 6 has a flexible electrical connection function that the 2U chassis no longer strictly depends on the specific specifications of the motherboard 2, and can flexibly adapt to the position of the PCIe slot 20 of different motherboards 2. At the same time, it can reliably install graphics cards and provide good heat dissipation for the full-height dual-width graphics card 4, thus improving the compatibility and versatility of the 2U chassis.
[0028] In this embodiment, the graphics card bracket 5 includes an air guide shroud 51. Along the direction away from the fan assembly 3, the air guide shroud 51 has a flared opening with a smaller opening, which corresponds to the fan assembly 3. The ventilation holes 50 are located on the side of the air guide shroud 51 away from the fan assembly 3. Through the flared opening design of the air guide shroud 51, the air intake of the fan assembly 3 can be increased, thereby improving the heat dissipation efficiency of the full-height, double-width graphics card 4.
[0029] Specifically, the side of the air guide shroud 51 away from the fan assembly 3 is provided with a first fixing hole 510. The first fixing hole 510 is spaced apart from the ventilation hole 50, and a first screw connects the first fixing hole 510 to the full-height dual-width graphics card 4. One end of the full-height dual-width graphics card 4 is fixed to the first fixing hole 510 of the air guide shroud 51 by the first screw, and the other end of the full-height dual-width graphics card 4 is fixed to the rear window panel 10 of the chassis, thereby ensuring the installation stability of the full-height dual-width graphics card 4 inside the chassis body 1.
[0030] As a further preferred solution, the rear window panel 10 of the chassis has a rear window slot 101. The full-height dual-width graphics card 4 has a full-height baffle 41 on the side near the rear window panel 10 of the chassis. The full-height baffle 41 is inserted into the rear window slot 101 and is fixedly connected to the rear window panel 10 of the chassis by a second screw. The other end of the full-height dual-width graphics card 4 adopts a plug-in + screw fixing method to ensure the structural matching degree between the full-height dual-width graphics card 4 and the chassis body 1.
[0031] The air guide shroud 51 has a first baffle 511 on the side away from the fan assembly 3, and the first baffle 511 has a first hole 512. The graphics card bracket 5 also includes a base 52, and the upper part of the base 52 has a second baffle 521, and the second baffle 521 has a second hole 522. The first baffle 511 and the second baffle 521 are arranged parallel to each other, and a third screw passes through the first hole 512 and the second hole 522. The base 52 is first fixed to the bottom plate of the chassis body 1, and then the air guide shroud 51 is installed on the base 52 using the third screw, thus achieving the purpose of integral installation of the graphics card bracket 5 inside the chassis body 1.
[0032] It should be noted that, along the height of the chassis body 1, the motherboard 2 and the full-height dual-width graphics card 4 are spaced apart and form a heat dissipation channel. The base 52 has a first heat dissipation hole 523, and the rear window panel 10 of the chassis has a second heat dissipation hole 102. The second heat dissipation hole 102 is arranged alternately with the rear window slot 101. The first heat dissipation hole 523 and the second heat dissipation hole 102 are respectively connected to the heat dissipation channel. The heat dissipation channel is directly connected to the full-height dual-width graphics card 4. The first heat dissipation hole 523 and the second heat dissipation hole 102 increase the air intake area and the air exhaust area, thereby improving the heat dissipation efficiency of the full-height dual-width graphics card 4.
[0033] In this embodiment, the flexible flat cable 6 is arranged in a zigzag shape within the heat dissipation channel. One end of the flexible flat cable 6 is fixed to the flexible flat cable bracket 7 and electrically connected to the connector of the full-height, double-width graphics card 4. Specifically, one end of the flexible flat cable 6 has a first slot 61, and the other end of the flexible flat cable 6 has a first connector 62. The first slot 61 is fixedly installed on the flexible flat cable bracket 7, and the first connector 62 is electrically connected to the PCIe slot 20 of the motherboard 2.
[0034] As a further preferred embodiment, along the width direction of the chassis body 1, the first slot 61 is connected to the connector of the full-height dual-width graphics card 4; along the height direction of the chassis body 1, the first connector 62 is connected to the PCIe slot 20 of the motherboard 2. This maximizes the use of the space in the width direction of the chassis body 1, facilitating the connection between the first slot 61 of the flexible cable 6 and the connector of the full-height dual-width graphics card 4.
[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
