Description

Technical Field

[0001] This specification relates to the field of mechanical technology, and in particular to a circuit board assembly and a server. Background Technology

[0002] With the development of electronic technology, the number of components deployed inside an electronic device is increasing, especially in servers. Due to the requirements for computing, storage, and switching functions, data exchange between functional modules in servers needs to be achieved through cables. Furthermore, due to the need for effective heat dissipation of functional modules, air ducts are installed on the heat-generating components of the functional modules.

[0003] In current servers, in order to ensure heat dissipation and the safety of cable routing, air ducts need to support the cables. When staff need to maintain functional modules, they need to unplug the cables and remove the air ducts. Due to the cumbersome operation process, the efficiency of staff in maintaining servers is greatly reduced. Summary of the Invention

[0038] This application provides a circuit board assembly 100, such as Figure 1 As shown, it includes:

[0039] Circuit board 1, on which a heating device 10 is provided, and other devices may also be provided on the circuit board 1. A server may be provided with a variety of functional modules, such as a switching module for data exchange, a storage module for data storage, and a computing module for data processing. The heating device 10 may include a processor, an image processing unit, and a heat sink provided thereon.

[0040] Cable 2 is electrically connected to the circuit board 1. Cable 2 can include various types, such as cables that connect to the power module for power transmission, cables that connect to the computing module, switching module and storage module, etc.

[0041] An air guide shroud 3 is disposed above the circuit board 1 and forms an air duct 30. The heating device 10 is located in the air duct 30. A first cable receiving groove 31 is formed on the upper surface 3A of the air guide shroud 3.

[0042] The air guide cover 3 is detachably provided, and the detachment position P is located in the first cable receiving groove 31.

[0043] When assembling the server, the circuit board 1 can be placed in the server chassis first. Then, the detachable air guide shroud 3 can be installed on the circuit board 1 and cover the heat-generating device 10 on the circuit board 1. Then, the circuit board 1 can be connected by the cable 2 and placed into the first cable receiving slot 31.

[0044] When staff need to maintain the server, such as Figure 2 As shown, the left air guide cover 3 can be removed while the right air guide cover 3 remains, thus enabling maintenance of the components on the left circuit board 1. Similarly, the components on the right circuit board 1 can also be maintained. During maintenance, when one side of the air guide cover 3 is removed, part of the first cable receiving groove 31 on the other side of the air guide cover 3 can continue to support the cable 2.

[0045] In this way, when staff need to maintain the server, they can maintain the components on the circuit board without disassembling the cables and all the air ducts, thereby improving the server maintenance efficiency.

[0046] Optional, such as Figure 1 As shown, the air guide shroud 3 further includes:

[0047] Support parts 32 are respectively disposed on the lower surface 3B of the air guide shroud 3, extend toward the circuit board 1, and abut against the circuit board 1.

[0048] The support part 32 can be columnar, extending from the lower surface 3B of the air guide shroud 3 toward the circuit board 1, abutting against the circuit board 1, and supporting the air guide shroud 3 through the circuit board 1.

[0049] Furthermore, the support portion 32 is disposed on both sides of the separation position P.

[0050] By providing support parts 32 on both sides of the separation position P, the air guide shroud 3 can be supported separately after separation, so as to avoid the air guide shroud 3 on the other side becoming loose when one side of the air guide shroud 3 is disassembled, thus preventing the air guide shroud 3 from falling and damaging the circuit board 1.

[0051] Optionally, the air guide shroud 3, as... Figure 1 , 2 As shown, it also includes:

[0052] The mounting parts 33 are respectively formed on both sides of the air guide shroud 3 away from the first cable receiving groove 31.

[0053] In a server with a large number of cables 2, the air guide shroud 3 may bear significant pressure. Insufficient support may lead to damage to the air guide shroud 3. To improve the support of the air guide shroud 3, mounting parts 33 can be provided on both sides of the air guide shroud 3. These mounting parts 33 can hold the side panels 201A of the server 200's enclosure 201, thereby improving the support of the air guide shroud 3 and reducing the impact of cable 2 pressure on the reliability of the air guide shroud 3's support.

[0054] Furthermore, the mounting portion 33 is located on both sides near the front edge of the air guide shroud 3 and near the rear edge of the air guide shroud 3.

[0055] By attaching the hanger 33 at the front and rear ends of the air guide cover 3, the air guide cover 3 can be given stronger support, further reducing the impact of the cable 2 on the support reliability of the air guide cover 3.

[0056] Optionally, the air guide shroud 3, as... Figure 2 As shown, it also includes:

[0057] The second cable receiving groove 34 is disposed between the first cable receiving groove 31 and the two sides of the air guide shroud 3 away from the first cable receiving groove 31.

[0058] The second cable receiving groove 34 can be formed on the upper surface 3A or the lower surface 3B of the air guide shroud 3, with the interface set according to actual needs.

[0059] In such Figure 2 In the circuit board assembly 100 shown, the cable 2 can be extended along the side panel 201A of the enclosure 201 of the server 200.

[0060] Optionally, the air duct 30, such as Figure 3 As shown, it includes:

[0061] An air inlet 30B is formed in the air inlet cavity 30A near the rear end of the air guide shroud 3;

[0062] An air outlet 30C is formed at the front end of the air inlet cavity 30C near the air guide shroud 3. The air outlet cavity 30C is connected to the air inlet cavity 30A. The width of the front end of the air outlet cavity 30C near the air guide shroud 3 is greater than the width of the air inlet cavity 30A.

[0063] By varying the widths of the air inlet cavity 30A and the air outlet cavity 30C, the air velocity in the air duct 30 can be increased, thereby improving the heat dissipation efficiency inside the server through the air guide shroud 3.

[0064] Optionally, an auxiliary air inlet 35 communicating with the air outlet cavity 30C is also provided on the air guide shroud 3.

[0065] To increase the air intake of the air guide shroud 3, an auxiliary air intake 35 can be opened on the air guide shroud 3.

[0066] Optionally, the air guide shroud 3, as... Figure 3 As shown, it includes:

[0067] First cover 36;

[0068] The second cover 37 is formed separately from the first cover 36 and the second cover 37. The first cover 36 and the second cover 37 abut against each other, and the first cable receiving groove 31 is formed between the first cover 36 and the second cover 37.

[0069] The first cover 36 and the second cover 37 can be connected by a locking mechanism. Through holes can be provided on the first cover 36 and the second cover 37, and the two can be locked by inserting a locking hook into the through hole.

[0070] Of course, the locking mechanism for the first cover 36 and the second cover 37 is not limited to this.

[0071] Correspondingly, this application also provides a server 200, such as Figure 1-3 As shown, it includes:

[0072] Box 201, which can be formed by side panels 201A, bottom panel 201B and top panel; and,

[0073] The circuit board assembly 100 described above.

[0074] The technical solutions provided in the embodiments of this specification may include the following beneficial effects:

[0075] In this embodiment of the specification, an air guide is provided in the circuit board assembly. The air guide is detachably provided, and the detachable part is located in the first cable receiving groove. When the circuit board needs maintenance, a part of the air guide can be removed separately, while the other part can continue to support the cable. It is not necessary to completely remove the cable and the air guide, which improves the maintenance efficiency of the server.
