Description

Technical Field

[0001] This utility model belongs to the field of computer-related technology, specifically relating to a server chassis with waste heat recovery function. Background Technology

[0002] In today's rapidly developing information technology landscape, servers, as core devices for data storage and processing, are increasingly widely used. Servers generate a significant amount of heat during operation; if this heat is not dissipated effectively and promptly, it will severely impact server performance and lifespan. Traditional server chassis cooling methods often have numerous shortcomings.

[0003] On the one hand, traditional air intake designs result in limited air intake volume and a small intake range. When hot air is expelled from inside the chassis, fresh air cannot quickly enter the chassis from multiple locations and over a large area, leading to poor air circulation and difficulty in rapidly dissipating the heat generated by the server. This results in excessively high internal temperatures, affecting the server's stability and performance. On the other hand, traditional chassis have relatively weak protective measures. In real-world usage scenarios, server chassis may be subjected to various accidental collisions or frictions. The lack of effective protective structures can easily lead to damage to the chassis and internal equipment, increasing maintenance costs and equipment downtime. Utility Model Content

When hot air is discharged, it is difficult for fresh air to enter the chassis quickly and in a large area and from multiple locations, resulting in poor air circulation, excessive chassis temperature, and affecting server stability and performance. At the same time, the protective measures are relatively weak. In the face of accidental collisions or friction, the chassis and internal equipment are easily damaged due to the lack of effective protective structure, resulting in increased maintenance costs and longer downtime.

[0008] Preferably, the large-area air intake and protection device further includes a locking sleeve and an anti-detachment pin. The rear ends of the long strip-shaped U-shaped protective sleeve A and the long strip-shaped U-shaped protective sleeve B are both provided with locking sleeves. The locking sleeve has a pin hole vertically inside, and an anti-detachment pin is inserted into the pin hole. The anti-detachment pin blocks the rear end of the long strip-shaped U-shaped air intake sleeve.

[0009] Preferably, each of the four corners of the bottom of the chassis body is provided with a mounting foot, and the bottom of each mounting foot is affixed with a rubber anti-slip pad. A power button is provided at the front of the chassis panel near the upper right corner, and a restart button is provided to the left of the power button.

[0014] This invention incorporates a novel large-area air intake and protection device on the front and left / right sides of the server chassis. Multiple such devices are installed. As multiple cooling fans inside the top of the chassis exhaust hot air, fresh air simultaneously enters the chassis through these large-area air intake and protection devices, creating a smooth airflow channel. This significantly improves air circulation within the chassis. Compared to traditional intake methods, this large-area, multi-position intake design significantly increases the air intake volume, more quickly removing heat generated inside the chassis and effectively reducing the internal temperature. This provides a more reliable environment for stable server operation. Furthermore, the large-area air intake and protection device not only provides air intake but also plays a crucial protective role.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides, for example Figure 1-5The server chassis shown includes a chassis body 3 and a chassis panel 1 located at the front of the chassis body 3. A data connection backplane 8 is located at the rear of the chassis body 3. A rectangular replacement and maintenance window is located inside the right end of the chassis body 3, and a replacement and maintenance protective plate 7 is installed in the rectangular replacement and maintenance window. The replacement and maintenance protective plate 7 is fixed to the chassis body 3 with screws near its four corners. Each of the four corners of the bottom of the chassis body 3 is provided with mounting feet, and rubber anti-slip pads are affixed to the bottom of the mounting feet. A power button 5 is located near the upper right corner of the front of the chassis panel 1. A restart button 4 is located to the left of the power button 5. Both the restart button 4 and the power button 5 are physical push-button buttons. The top center of the chassis body 3 and the interior of its front and rear sides are also provided with... The system includes multiple circular heat dissipation windows 9, each housing a cooling fan 10. Each cooling fan 10 has a waste heat recovery mechanism 6 attached to its top. Multiple large-area air intake and protection devices 2 are equidistantly connected to the left and right ends of the chassis body 3 and the front end of the chassis panel 1, arranged equidistantly from bottom to top. While hot air is expelled, these devices maintain air circulation within the chassis. Fresh air enters the chassis body 3 through these devices, replenishing the space created by the expelled hot air, forming a complete air circulation system. This ensures the temperature inside the chassis remains within a reasonable range, guaranteeing stable server operation.

[0023] like Figure 1 and Figure 4 As shown, the waste heat recovery mechanism 6 consists of a circular heat dissipation window 9, a heat dissipation fan 10, a waste heat collection cover 11, a fixing flange 12, a waste heat exhaust fan box 13, and a waste heat exhaust external interface 14. The waste heat collection cover 11 is provided with a fixing flange 12 at the bottom of its outer side. The fixing flange 12 is fixed to the top outer wall of the chassis body 3 by multiple screws. The waste heat collection cover 11 is fitted over the top of multiple heat dissipation fans 10. The hot air exhausted by multiple heat dissipation fans 10 is collected in the waste heat collection cover 11. During the operation of the server, a large amount of heat is generated, and the internal temperature of the chassis body 3 rises. The heat dissipation fans 10 in the multiple circular heat dissipation windows 9 provided at the top center of the chassis body 3 and on its front and rear sides start to work, transporting the hot air inside the chassis upward. This hot air is collected by the waste heat collection cover 11. The waste heat collection cover 11 is fixed to the top outer wall of the chassis body 3 by screws through the fixing flange 12, tightly fitted over the top of multiple heat dissipation fans 10, ensuring that the hot air does not leak, and achieving efficient collection of the hot air generated inside the chassis.

[0024] like Figure 1 and Figure 4As shown, a waste heat exhaust fan box 13 is provided at the middle section of the top of the waste heat collection hood 11. The air inlet of the waste heat exhaust fan box 13 is inserted into the inside of the top of the waste heat collection hood 11, and the air inlet of the waste heat exhaust fan box 13 is connected to the inside of the waste heat collection hood 11. A waste heat exhaust port 14 is provided at the rear end of the waste heat exhaust fan box 13. The cooling fan 10 delivers hot air from inside the chassis body 3 into the waste heat collection hood 11. The waste heat exhaust fan box 13 exhausts the hot air collected in the waste heat collection hood 11 through the waste heat exhaust port 14 through its internal exhaust fan. The waste heat exhaust port 14 can be connected to... The external waste heat reuse pipeline is directly connected. The waste heat exhaust fan box 13 set in the middle section of the top of the waste heat collection hood 11 plays a key role. The air inlet of the waste heat exhaust fan box 13 is connected to the inside of the waste heat collection hood 11. After the exhaust fan inside is started, the hot air collected in the waste heat collection hood 11 is discharged through the waste heat exhaust external interface 14 at the rear end. The waste heat exhaust external interface 14 can be directly connected to the external waste heat reuse pipeline, so that the collected hot air can be transported to the external system for reuse, such as for preheating other equipment or space heating, thus realizing the function of waste heat recovery.

[0025] like Figure 1 and Figure 5As shown, the large-area air intake and protection device 2 includes a long strip-shaped U-shaped protective sleeve A15, a panel protective strip 16, a long strip-shaped U-shaped protective sleeve B17, an air intake strip hole 18, and a long strip-shaped loop-shaped air intake sleeve 20. Long strip-shaped loop-shaped air intake sleeves 20 are inserted and fixed inside the left end of the chassis body 3 and inside the replacement and maintenance protective plate 7. Both long strip-shaped loop-shaped air intake sleeves 20 are arranged longitudinally front and rear. Long strip-shaped U-shaped protective sleeves A15 are respectively fitted onto the outside of the two long strip-shaped loop-shaped air intake sleeves 20. Along with the elongated U-shaped protective sleeve B17, the elongated U-shaped protective sleeve A15 is located at the left end of the chassis body 3, and the elongated U-shaped protective sleeve B17 is located at the right end of the replacement and maintenance protective plate 7. The front ends of the elongated U-shaped protective sleeve A15 and the elongated U-shaped protective sleeve B17 are connected by a panel protective strip 16, which is attached to the front end of the chassis panel 1. The interior of the left end of the elongated U-shaped protective sleeve A15 and the interior of the right end of the elongated U-shaped protective sleeve B17 are densely covered with air intake holes 18. The two sets of air intake holes 18 are located on the left and right sides of the two elongated U-shaped air intake sleeves 20, respectively. The elongated U-shaped protective sleeves A15 and B17 are respectively fitted onto the outside of the longitudinally arranged elongated U-shaped air intake sleeves 20, and a panel protective strip 16 is connected to the front end of both of them. The panel protective strip 16 is attached to the front end of the chassis panel 1. The left end of the elongated U-shaped protective sleeve A15 and the right end of the elongated U-shaped protective sleeve B17 are densely covered with air intake holes. The two sets of air intake holes 18 are located on the left and right sides of the two elongated loop-shaped air intake sleeves 20, respectively. When the cooling fan 10 at the top of the chassis body 3 exhausts the hot air inside the chassis, a negative pressure is formed inside the chassis. Under the action of the pressure difference, the fresh air outside enters the elongated loop-shaped air intake sleeves 20 through the air intake holes 18, and then enters the interior of the chassis body 3, providing a large area and multiple air intake channels for the chassis to meet the amount of fresh air required for heat dissipation inside the chassis.

[0026] like Figure 1 and Figure 5 As shown, both the elongated U-shaped protective sleeve A15 and the elongated U-shaped protective sleeve B17 can slide back and forth on the outside of the elongated U-shaped air intake sleeve 20. When the panel protective strip 16 is attached to the front outer wall of the chassis panel 1, the rear ends of the elongated U-shaped protective sleeve A15 and the elongated U-shaped protective sleeve B17 are flush with the rear end of the elongated U-shaped air intake sleeve 20. The elongated U-shaped protective sleeve A15, the panel protective strip 16, the elongated U-shaped protective sleeve B17, and the elongated U-shaped air intake sleeve 20 are all made of aluminum alloy. Aluminum alloy has high strength and a certain degree of toughness. During the daily use of the server chassis, the elongated U-shaped protective sleeve A15, the panel protective strip 16, the elongated U-shaped protective sleeve B17, and the elongated U-shaped air intake sleeve 20 together constitute a protective structure that can withstand a certain degree of external collision and friction, prevent the chassis from being physically damaged, and play a good protective role for the server equipment inside the chassis.

[0027] like Figure 1 and Figure 5 As shown, the large-area air intake and protection device 2 also includes a locking sleeve 19 and an anti-detachment pin 21. Locking sleeves 19 are provided at the rear ends of both the elongated U-shaped protective sleeves A15 and B17. A pin hole is vertically provided inside the locking sleeve 19, and an anti-detachment pin 21 is inserted into the pin hole. The anti-detachment pin 21 blocks the rear end of the elongated U-shaped air intake sleeve 20. Both the elongated U-shaped protective sleeves A15 and B17 can slide back and forth on the outside of the elongated U-shaped air intake sleeve 20. This design mainly aims to… The advantage lies in its ease of disassembly and assembly. When the internal components of the server chassis need to be replaced or repaired, the anti-detachment pin 21 can be pulled out from the pin hole of the locking sleeve 19 first. Then, the long strip U-shaped protective sleeve A15 and the long strip U-shaped protective sleeve B17 can be slid out along the long strip U-shaped air intake sleeve 20. Then, the panel protective strip 16 can be removed. At this time, the protective plate 7 can be removed, replaced, and repaired. The internal components of the server chassis can be replaced and repaired in a timely manner. After the repair is completed, the large-area air intake and protection device 2 can be reinstalled by reversing the operation.
