Description

Technical Field

[0001] This application relates to the field of server heat dissipation technology, and more particularly to a server. Background Technology

[0002] The most common heat dissipation method in servers is air cooling. However, the existing server architecture design has poor air cooling performance, which is difficult to meet the basic heat dissipation requirements of components. Furthermore, the maturity of the heat dissipation architecture is reduced, resulting in poor stability. Utility Model Content

[0003] This application provides a server that at least solves the problem of poor heat dissipation in related technologies.

[0004] This application provides a server, including: a chassis, the chassis including a body and a cover, the body having air inlets and air outlets arranged in a front and rear manner, the cover covering the body, the cover having an air outlet; an expansion bracket, the expansion bracket having a top plate, the top plate having a through hole, the through hole communicating with the air outlet for airflow, and the through hole and the air outlet at least partially overlapping in projection.

[0005] This application provides air outlets and through holes on the top plate of the cover and the expansion bracket, respectively. This allows airflow to exit from the cover through the through holes and air outlets when passing over the expansion bracket, thus achieving sufficient heat dissipation for the components mounted on the expansion bracket. Specifically, the airflow enters the enclosure from the inlet and then flows to the expansion bracket. At this point, the airflow is divided into two parts: one part is blown out of the enclosure from the outlet, and the other part is blown out of the enclosure from the outlet. This achieves efficient heat dissipation at the expansion bracket, improves the heat dissipation effect, and enables precise distribution of airflow throughout the unit, maximizing the utilization of heat dissipation resources. The above configuration increases the structural strength of the expansion bracket by utilizing the top plate, effectively protecting the components inside. It also allows the server to form a dual-exhaust architecture with two outlets: the exhaust end and the exhaust port. Compared to traditional configurations, this allows for upward auxiliary exhaust of hot air, creating a "front window array air intake + rear window and cover plate exhaust" cooling structure. This reduces the impact of the top plate on the cooling effect of the expansion bracket, increases airflow within the chassis, and improves overall cooling performance. Attached Figure Description

[0022] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] To address the problem of poor heat dissipation in servers in related technologies, this application provides a server.

[0024] like Figures 1 to 11 The server shown includes a chassis 10 and an expansion bracket 50. The chassis 10 includes a housing 11 and a cover plate 12. The housing 11 has an air inlet and an air outlet arranged in a front-to-back manner. The cover plate 12 covers the housing 11 and has an air outlet 13. The expansion bracket 50 has a top plate 51 with a through hole 52. The through hole 52 communicates with the air outlet 13, and the through hole 52 and the air outlet 13 at least partially overlap in projection.

[0025] In this embodiment, air outlets 13 and through holes 52 are respectively provided on the cover plate 12 and the top plate 51 of the expansion bracket 50. This allows airflow to pass through the through holes 52 and air outlets 13 and exit from the cover plate 12, thereby achieving sufficient heat dissipation for the devices installed on the expansion bracket 50. Specifically, the airflow enters the housing 11 from the air inlet and then flows to the expansion bracket 50. At this point, the airflow is divided into two parts: one part is blown out of the housing 10 from the air outlet, and the other part is blown out of the housing 10 from the air outlet 13. This achieves efficient heat dissipation at the expansion bracket 50, improves the heat dissipation effect, realizes fine distribution of airflow throughout the machine, and maximizes the utilization rate of heat dissipation resources. The above-mentioned configuration increases the structural strength of the expansion bracket 50 by using the top plate 51, effectively protecting the components inside the expansion bracket 50. On the other hand, it enables the server to form a dual-airflow architecture with two air outlets, the air outlet and the air outlet 13. Compared with the traditional configuration, it can achieve upward auxiliary exhaust of hot air, making the whole machine form a heat dissipation architecture of "front window array air intake + rear window and cover plate air exhaust". This reduces the impact of the top plate 51 on the heat dissipation effect of the expansion bracket 50, increases the air flow rate and velocity inside the chassis 10, and thus improves the heat dissipation effect.

[0026] In this embodiment, when a person normally places the server, the side of the server closest to the person is considered the front end, and the side furthest from the person is considered the rear end. Figure 1 The direction is such that the lower left end is the front end and the upper right end is the rear end. In this embodiment, the air inlet is located at the front end and the air outlet at the rear end, thus forming a front-to-back airflow cooling direction. The direction perpendicular to the front-to-back direction and extending laterally is the width direction, which is also the left-right direction for personnel. In this embodiment, the projection overlap means that the projection of the through hole 52 on the cover plate 12 at least partially overlaps with the air outlet 13.

[0027] This embodiment uses the example of expansion card 40 mounted on expansion bracket 50 and hard disk 20 mounted on hard disk tray 70 for illustration. Correspondingly, top plate 51 is located below cover plate 12 and between cover plate 12 and expansion card 40. Of course, the devices mounted on the bracket and tray can also be adjusted as needed.

[0028] The server in this embodiment also includes a hard drive tray 70 and a fan 30. The hard drive tray 70 and fan 30 are disposed inside the chassis 10, and are arranged sequentially from the air inlet to the air outlet, with the hard drive tray 70, fan 30, and expansion bracket 50 spaced apart. By arranging the hard drive tray 70, fan 30, and expansion bracket 50 sequentially from the air inlet to the air outlet, this embodiment creates a hard drive area, a fan area, and an expansion card area inside the chassis 10. During air cooling, the airflow enters the chassis 10 from the air inlet and, driven by the fan 30, passes sequentially through the hard drive 20, fan 30, and expansion card 40, forming a three-section airflow architecture. This clear airflow path improves heat dissipation and meets the basic heat dissipation requirements of the server's core components under standard configuration. Furthermore, the architecture is mature and offers strong operational stability.

[0029] like Figure 2 As shown, the server in this embodiment also includes a motherboard, which is installed inside the chassis 10 and located on the bottom plate of the chassis 10. The motherboard is equipped with devices such as a processor and memory 110. The processor and / or memory 110 are located on the side where the fan 30 exhausts air, that is, the processor and / or memory 110 are located between the fan 30 and the expansion bracket 50, so that after the airflow passes through the fan 30, part of it acts on the processor, memory 110 and other devices, and part of the airflow passes through the expansion card 40 to dissipate heat before being blown out through the air outlet 13.

[0030] like Figures 1 to 3 As shown, in this embodiment, the enclosure 11 is used to house the hard drive 20, the fan 30, and the expansion card 40. The enclosure 11 includes two side plates and a bottom plate. The bottom plate is the bottom of the enclosure 11. The side plates are upright and connected to the bottom plate. Side plates are provided on both sides of the bottom plate parallel to the length direction, while the other opposite sides and the top are provided with openings. The opposite sides serve as the air inlet and air outlet, respectively. The cover plate 12 is placed over the opening at the top of the enclosure 10, so that when the airflow enters the enclosure 10 from the air inlet, it flows towards the air outlet under the restriction of the inner wall of the enclosure 10, realizing the airflow path that passes through the hard drive 20, the fan 30, and the expansion card 40 in sequence.

[0031] In this embodiment, the air outlet 13 is mainly located at the position of the expansion card 40. That is, the air outlet 13 cooperates with the expansion card 40 to dissipate heat from the expansion card 40. Specifically, the projection of the expansion card 40 on the plane of the cover plate 12 at least partially overlaps with the air outlet 13, thus aligning the expansion card 40 and the air outlet 13 vertically at least partially. This allows the airflow to the expansion card 40 to be divided into two parts: one part is blown out of the chassis 10 from the outlet, and the other part is blown out of the chassis 10 from the air outlet 13. This achieves efficient heat dissipation for the expansion card 40, improves the heat dissipation effect, and enables precise distribution of airflow throughout the system, maximizing the utilization of heat dissipation resources. Simultaneously, because the expansion card 40 is closer to the outlet than components such as the hard drive 20, the airflow can be fully applied to upstream devices such as the hard drive 20, only being diverted just before being blown out from the outlet to ensure airflow utilization and prevent premature airflow dissipation. Of course, in addition to setting the air outlet 13 at the expansion card 40, air outlets can also be set on the cover plate 12 at the positions corresponding to other devices, such as the positions on the cover plate 12 corresponding to the memory 110, processor and other devices.

[0032] In this embodiment, a power supply is also located at the rear end inside the chassis 10, near the air outlet. The power supply and the expansion card 40 are arranged horizontally and perpendicular to the front-to-back direction. The expansion card 40 is offset relative to the central axis of the chassis 10 in the front-to-back direction, so that the air outlet 13 corresponding to the expansion card 40 is also offset to ensure compatibility between the air outlet 13 and the expansion card 40. Of course, when the expansion card 40 is located in other positions, the position of the air outlet 13 can be adjusted accordingly to match the position of the expansion card 40. The offset setting mentioned in this embodiment refers to the asymmetrical setting of the expansion card 40 relative to the central axis, which can be offset to one side of the central axis.

[0033] like Figure 4 As shown, the expansion bracket 50 is mounted on the inner wall of the chassis 10, and the expansion card 40 is mounted on the expansion bracket 50, thus enabling the expansion bracket 50 to act as an intermediate component, achieving the purpose of installing and fixing the expansion card 40 inside the chassis 10. In this embodiment, the expansion bracket 50 adopts a frame structure, which is connected to the chassis 10 externally, and at least a portion of the expansion bracket 50 is located between the expansion card 40 and the cover plate 12, thereby achieving both the installation and protection of the expansion card 40.

[0034] Based on the above form, in this embodiment, the through hole 52 and the air outlet 13 are at least partially projected and aligned axially. In this embodiment, the air outlet 13 and the through hole 52 are preferably aligned vertically. The expansion card 40 is directly below the through hole 52. In this way, when the airflow passes through the expansion card 40, it can flow upward and pass through the through hole 52 to reach the air outlet 13, and then be blown out from the air outlet 13. This ensures the effect of upward auxiliary airflow and avoids the setting of the expansion bracket 50 from obstructing the upward airflow.

[0035] Optionally, the number of expansion brackets 50 and expansion cards 40 can be set as needed, either one or more. When multiple expansion brackets 50 are provided, it is preferable that each expansion bracket 50 has at least one through hole 52, so that each expansion bracket 50 can receive upward airflow for heat dissipation. Correspondingly, the number of air outlets 13 can also be set as needed, either one or more. When there is one air outlet 13, it can be a long strip-shaped opening with a relatively long length, preferably long enough to cover all through holes 52, so that it can communicate and cooperate with multiple through holes 52. When multiple air outlets 13 are provided, they can be connected one-to-one with each through hole 52, or one air outlet 13 can be connected to multiple through holes 52, or multiple air outlets 13 can be connected to one through hole 52, or both of the above methods can be set simultaneously. Regardless of the settings, as long as the air outlet 13 and the through hole 52 can cooperate with each other so that the airflow can be smoothly blown out of the air outlet 13 through the through hole 52, it is acceptable.

[0036] Preferably, in this embodiment, the air outlet 13 is offset relative to the central axis extending forward and backward from the chassis 10. This allows the air outlet 13 to be offset on the cover plate 12, thereby increasing the exhaust cross-sectional area of ​​the area where the expansion card 40 is located, reducing hot air retention at the high-power expansion card 40. This effectively alleviates heat accumulation in the expansion card area compared to a traditional closed cover design, improving the heat dissipation limit under high-density configurations. Furthermore, this configuration only optimizes the opening design of the cover plate 12 and the expansion bracket 50, without altering the core layout of the entire machine or the assembly logic of existing components. It eliminates the need for remolding core structural components, keeping expansion and modification costs controllable and allowing for rapid optimization based on the original factory model. In addition, the expanded structure is fully compatible with all existing components such as the hard drive tray 70 and fan 30, requiring no replacement parts and directly adapting to the original configuration, demonstrating strong adaptability.

[0037] In this embodiment, a positioning post is provided on the inner wall of the chassis 10. Correspondingly, the expansion bracket 50 has a positioning hole. The positioning post and the positioning hole can be inserted and positioned together, so that when the expansion bracket 50 is installed, the expansion bracket 50 can be positioned at a specific position inside the chassis 10 through the cooperation between the positioning post and the positioning hole, thereby ensuring the accuracy of the installation position of the expansion bracket 50 and ensuring that the through hole 52 on the expansion bracket 50 can be aligned and fitted with the air outlet 13. Moreover, this method allows the expansion bracket 50 to be installed without screws, and can be directly installed by inserting it into the positioning post and the positioning hole, realizing tool-free installation and reducing the difficulty and complexity of installation.

[0038] like Figure 5 and Figure 6 As shown, in this embodiment, in order to ensure the stability of the connection between the expansion bracket 50 and the expansion card 40, the server also includes a limiting member 60. The expansion bracket 50 has a mounting slot for installing the expansion card 40, thereby enabling the expansion card 40 to be installed on the expansion bracket 50. The limiting member 60 and the expansion bracket 50 form a movable connection. The limiting member 60 is used to block or prevent the removal of the expansion card 40 installed on the expansion bracket 50. The limiting member 60 has a locked position and an unlocked position. When the limiting member 60 is in the locked position, it prevents the expansion card 40 from being removed from the expansion bracket 50. This keeps the expansion card 40 locked on the expansion bracket 50, improving the firmness of the fit between the expansion card 40 and the expansion bracket 50 and preventing the expansion card 40 from accidentally falling off. When it is necessary to remove the expansion card 40, the limiting member 60 switches to the unlocked position. At this time, the limiting member 60 exits the removal path of the expansion card 40, thus preventing the removal of the expansion card 40 and allowing it to be removed smoothly. The above method can achieve tool-free installation and removal of the expansion card 40, with higher efficiency, and is suitable for the operational needs of routine data center maintenance scenarios.

[0039] Preferably, in this embodiment, the mounting slot and the limiting member 60 are disposed on opposite sides of the expansion bracket 50. More specifically, in this embodiment, the limiting member 60 is disposed at the tail of the expansion bracket 50, so that when the expansion card 40 is installed in place, one end of the expansion card 40 is limited by the mounting slot, and the other end is limited by the limiting member 60, thereby ensuring that both sides of the expansion card 40 can be stably limited.

[0040] In this embodiment, the limiting member 60 is rotatably connected to the tail of the expansion bracket 50. The limiting member 60 includes a base 62 and a limiting arm 61. The base 62 is the main body of the limiting member 60 and is rotatably connected to the expansion bracket 50. The limiting arm 61 is connected to the base 62 and extends downward. Limiting arms 61 can be provided on both sides of the base 62, so that the limiting member 60 forms a U-shaped structure with the opening facing downward. When the expansion card 40 is installed on the expansion bracket 50 through the limiting member 60, the limiting member 60 can rotate downward. At this time, the limiting arm 61 extends between the side of the expansion bracket 50 and the expansion card 40, so that the expansion card 40 and the expansion bracket 50 form an interference fit with the limiting arm 61, thereby realizing the limiting function of the limiting member 60. Of course, the specific structural form of the limiting member 60 is not limited to the setting method described in this embodiment, and other limiting methods such as snap-fit ​​limiting can also be used.

[0041] The limiting member 60 in this embodiment also has an operating end, which can be connected to the top of the base 62. The operating end can be in the form of a plate, a handle, or other structures. Its function is to allow personnel to operate it, so that personnel can use the operating end to drive the limiting member 60 to rotate, thereby changing the limiting member 60 between the locked position and the unlocked position.

[0042] Optionally, the server also includes conductive foam for making contact with the expansion card 40 mounted on the expansion bracket 50 and for grounding. Specifically, the conductive foam can be located at the limiting arm 61. When the limiting arm 60 limits the expansion card 40, the conductive foam is in close contact with the metal fixing piece of the expansion card 40, thereby making contact and achieving the effect of grounding through the conductive foam.

[0043] like Figure 7 As shown, in this embodiment, the hard drive tray 70 and the chassis 10 adopt a sliding and detachable structure. Specifically, the hard drive tray 70 and the inner wall of the chassis 10 have a guide rail structure. The guide rail structure is located on the inner wall at the front end of the chassis 10 and can extend in the front-back direction, so that the hard drive tray 70 can be installed in the chassis 10 through the guide rail structure and can be detachably connected to the chassis 10 through the guide rail structure, thereby realizing the quick installation and removal of the hard drive 20.

[0044] like Figure 8As shown, to ensure that airflow can smoothly enter the chassis 10 from the air inlet, this embodiment provides a through-flow airflow channel 71 on the side of the hard drive tray 70 facing the air inlet, that is, at the front end of the hard drive tray 70. The size and position of the airflow channel 71 can be adjusted as needed. In this embodiment, it is preferable to provide airflow channels 71 in a relatively large area in the middle of the hard drive tray 70. The size of the airflow channel 71 can be relatively large without affecting the structural strength of the hard drive tray 70. A single airflow channel 71 can be set in the range of 6mm×20mm to 8mm×25mm. The total area of ​​the airflow channel 71 accounts for 45%-60% of the total area of ​​the front end of the hard drive tray 70, thereby ensuring that airflow can smoothly enter the chassis 10 for heat dissipation through the airflow channel 71 and ensure the heat dissipation effect.

[0045] like Figure 8 As shown, in this embodiment, the hard drive tray 70 includes a tray portion 72, a handle portion 73, and a locking member 74. The tray portion 72 is the main part of the hard drive tray 70, used to install and support the hard drive 20 and connect with the chassis 10. In this embodiment, the tray portion 72 adopts a three-section bent structure, forming a U-shaped structure with an opening facing backwards. Its opposite sides connect to the guide rail structure, thereby achieving a sliding connection with the chassis 10. The hard drive 20 is installed in the area in the middle of the U-shaped structure. The handle portion 73 is located at one end of the tray portion 72, more specifically at the front end. The handle portion 73 allows for operation by personnel; by pulling the handle portion 73, the hard drive tray 70 can be slid back and forth, enabling the installation and removal of the hard drive tray 70 and the hard drive 20 on it. Since the handle portion 73 is located at the front end, both the handle portion 73 and the front end of the tray portion 72 are provided with airflow channels 71. The handle 73 and the bracket 72 can be connected in a closable manner. Specifically, one end of the handle 73 can be rotatably connected to the bracket 72, while the other end can be opened or closed, thus exposing or concealing the hard drive 20. A locking element 74 is connected to the handle 73 and is located at the closable end of the handle 73. This allows the handle 73 to be locked or unlocked with the bracket 72 via the locking element 74. The locking element 74 restricts the insertion and removal of the hard drive bracket 70, effectively preventing maintenance personnel from accidentally inserting or removing the core data hard drive 20, reducing the probability of business interruption and data loss due to misoperation, and providing basic physical protection for the server's core data.

[0046] In this embodiment, the locking member 74 is rotatably mounted on the handle portion 73, so that the locking member 74 and the handle portion 73 are integrated together. The locking member 74 does not need to be removed; it can be unlocked and locked simply by rotating it. This prevents the component from being accidentally lost due to removal and also facilitates the unlocking and locking operation.

[0047] like Figure 9 and Figure 10 As shown, in this embodiment, one end of the locking member 74 is located at the rear side of the handle portion 73, and the other end is located at the front side of the handle portion 73. The end located at the front side of the handle portion 73 can be provided with a cross-shaped groove, a straight groove, a hand-tightening stud, or other structural forms to facilitate operation by hand or with tools. The end located at the rear side of the handle portion 73 has a locking end 75. Correspondingly, the bracket portion 72 has a locking hole 76. The locking end 75 has a non-circular structure or an eccentric structure. For example, the locking end 75 can be set as an eccentric cam or a straight protrusion. The structure of the locking hole 76 cooperates with the locking end 75. In this way, when the locking member 74 is locked, the locking member 74 rotates to a specific angle, so that the locking end 75 is misaligned with the locking hole 76, and the locking end 75 cannot extend into the rear side of the locking hole 76. A limiting fit is formed between the locking end 75 and the front surface of the locking hole 76 away from the handle 73, thereby preventing the locking end 75 from extending into the rear side of the locking hole 76 and preventing the handle 73 from rotating, thus achieving the locking between the handle 73 and the bracket 72. When unlocking, the operator rotates the locking member 74 by a predetermined angle so that the locking end 75 and the locking hole 76 are aligned front and back. At this time, the locking end 75 can pass through the locking hole 76, thereby allowing the handle 73 to rotate and release the lock between it and the bracket 72.

[0048] Optionally, components may or may not be provided between the fan 30 and the chassis 10 as needed. In one embodiment not shown, the server also includes a fan frame, on which the fan 30 is mounted. The fan frame is mounted on the chassis 10, thereby allowing the fan 30 to be mounted inside the chassis 10 through the fan frame, so that the fan 30 can stably provide power to the airflow of the entire machine and ensure the directional flow of airflow throughout the machine.

[0049] In this embodiment, the fan 30 does not have a fan frame on its outer side; instead, it is directly mounted to the inner wall of the chassis 10, thus forming a frameless fan unit. Specifically, as follows... Figure 11As shown, one of the fan 30 and the inner wall of the chassis 10 has mounting holes, and the other of the fan 30 and the inner wall of the chassis 10 has mounting posts 14. Taking the example of mounting holes on the outer side of the fan 30 and mounting posts 14 on the inner wall of the chassis 10, the mounting holes are located diagonally opposite the fan 30. Preferably, there are multiple mounting holes and mounting posts 14, which correspond one-to-one. In this way, when installing the fan 30, the fan 30 can be positioned and installed in the chassis 10 through the mounting posts 14 and mounting holes, thereby realizing the positioning and installation of the fan 30. Due to the frameless design, the space occupied by the traditional fan frame and cage bracket is saved, and a larger diameter and higher airflow fan unit can be selected in the same installation area, significantly improving heat dissipation capacity and airflow utilization.

[0050] like Figure 11 As shown, optionally, the specific number of fans 30 can be set as needed, either one or more. To ensure heat dissipation, taking the setting of multiple fans 30 as an example, at least some of the fans 30 are arranged along the width direction of the chassis 10. The server in this embodiment also includes an isolator 90. The isolator 90 can be made of foam or other structures. Isolators 90 can be set between the fans 30 and between the fans 30 and the inner wall of the chassis 10. On the one hand, the isolator 90 can fill and seal the gaps between the fans 30 and between the fans 30 and the inner wall of the chassis 10, thereby preventing airflow from flowing through the gaps on the outside of the fans 30, so that the airflow flows through the fans 30 as much as possible, preventing hot air backflow and airflow leakage, and ensuring heat dissipation. On the other hand, the isolator 90 can also fix and limit the installation of the fans 30, so that the position of the fans 30 is stable after installation. Moreover, the isolator 90 can also play a shockproof role, avoiding vibration from affecting the fans 30.

[0051] like Figure 2 As shown, the server in this embodiment also includes an air guide shroud 100. The air guide shroud 100 has an air guiding channel and is disposed at the outlet of the fan 30 facing the air outlet, that is, the air guide shroud 100 covers the rear end of the fan 30. This allows the airflow blown out by the fan 30 to be guided by the air guide shroud 100 and concentrated on the core heat-generating components such as the processor and memory 110, ensuring the overall heat dissipation effect of the server. Preferably, the gap between the air guide shroud 100 and the side wall of the chassis 10 is ≤1mm, thereby forming a sealed core airflow guiding channel.

[0052] The server in this embodiment can adopt a single-layer structure or a multi-layer structure. When using a multi-layer structure, multiple chassis 10 can be set up, stacked vertically. Each chassis 10 can house components such as a motherboard, hard drive 20, memory 110, processor, power supply, and expansion card 40. The server in this embodiment forms a universal architecture, with a mature component supply chain, controllable mass production costs, and can flexibly adapt to different expansion needs, possessing strong versatility.

[0053] It should be noted that "multiple" in the above embodiments refers to at least two.

[0054] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0055] In this embodiment, air outlets 13 and through holes 52 are respectively provided on the cover plate 12 and the top plate 51 of the expansion bracket 50. This allows airflow to pass through the through holes 52 and air outlets 13 and exit from the cover plate 12, thereby achieving sufficient heat dissipation for the devices installed on the expansion bracket 50. Specifically, the airflow enters the housing 11 from the air inlet and then flows to the expansion bracket 50. At this point, the airflow is divided into two parts: one part is blown out of the housing 10 from the air outlet, and the other part is blown out of the housing 10 from the air outlet 13. This achieves efficient heat dissipation at the expansion bracket 50, improves the heat dissipation effect, realizes fine distribution of airflow throughout the machine, and maximizes the utilization rate of heat dissipation resources. The above-mentioned configuration increases the structural strength of the expansion bracket 50 by using the top plate 51, effectively protecting the components inside the expansion bracket 50. On the other hand, it enables the server to form a dual-airflow architecture with two air outlets, the air outlet and the air outlet 13. Compared with the traditional configuration, it can achieve upward auxiliary exhaust of hot air, making the whole machine form a heat dissipation architecture of "front window array air intake + rear window and cover plate air exhaust". This reduces the impact of the top plate 51 on the heat dissipation effect of the expansion bracket 50, increases the air flow rate and velocity inside the chassis 10, and thus improves the heat dissipation effect.
