Automatic temperature control type server case

Abstract

This invention discloses an automatic temperature-controlled server chassis, specifically relating to the field of communication server equipment technology. The invention features a cooling jacket with air bladders on both sides in a deflated state. The cooling channel pulls the contact parts back under internal tension, while the telescopic part extends and opens, widening the opening of the cooling jacket for easy installation. This open structure easily covers each heat-generating module. After the cooling jacket is installed, an air pump is activated, inflating the air bladders. The air bladders gradually expand, pushing the contact parts connected to them towards the working element. The contact parts contract through the telescopic part, and the inner wall of the cooling jacket tightly adheres to the surface of the working element, forming a close contact state. This improves heat transfer efficiency and ensures that the coolant inside the jacket has good thermal conductivity and adhesion along the heat transfer path, dynamically adhering to the heat-generating surfaces of the working elements and modules, thereby improving cooling and heat transfer efficiency.

Description

Technical Field

[0001] This invention relates to the field of communication server equipment technology, specifically to an automatic temperature-controlled server chassis. Background Technology

[0002] Servers, as an important component of modern information infrastructure, are widely used in data centers, cloud computing platforms, edge computing nodes, and high-performance computing environments. With the continuous increase in computing density and hard drive capacity, the heat generated by servers is rising sharply, placing higher demands on their heat dissipation and temperature control systems. Traditional server chassis generally adopt a cooling method with fixed fan speed or manually adjustable fan speed, using a fixed number of fans and preset airflow channels for overall cooling.

[0003] The high-performance CPUs, GPUs, power supplies, hard drives, and other modules installed inside the server chassis generate a lot of heat during operation. The system cannot dynamically adjust the heat dissipation efforts based on the temperature rise of different components such as the CPU, GPU, power supply, and hard drive in real time, and cannot independently control the temperature. This leads to uneven distribution of heat dissipation resources, reduces the overall system efficiency, and causes overheating or energy waste when the load changes rapidly. Summary of the Invention

[0004] The purpose of this invention is to provide an automatically temperature-controlled server chassis to solve the problems mentioned in the background section.

[0005] The main technical problem solved by this invention is:

[0006] The inability to dynamically adjust the heat dissipation based on the temperature rise of different components inside the chassis in real time, and the inability to independently control the temperature, leads to uneven distribution of heat dissipation resources, reduces the overall system efficiency, and causes overheating or energy waste when the load changes rapidly.

[0007] This invention can be achieved through the following technical solutions:

[0008] An automatic temperature-controlled server chassis includes a chassis body, a sliding limiting unit installed on the inner wall of the chassis body, the sliding limiting unit including a load-bearing limiting seat that slides horizontally along the inner wall of the chassis body, four load-bearing limiting seats are provided, and the same mounting plate is snapped into the four load-bearing limiting seats. A power module and a storage module are installed inside the chassis body.

[0009] The power module and storage module together form the working module. The working module and the working components on the mounting plate are all fitted with water-cooled cooling jackets.

[0010] Both sides of the cooling jacket are provided with airbag components connected to an air pump via pipes. Each airbag component has a heat conduction channel connected to its inner end. The end of the heat conduction channel is connected to a contact component that contacts the working module or working element. Both ends of the contact component are provided with telescopic parts, and the contact component is located on the inner wall surface of the cooling jacket.

[0011] The cooling jacket is connected to a cooling channel at one end, and the outlet end of the cooling channel is connected to the inlet end of the heat conduction channel.

[0012] A further technical improvement of the present invention is that: the surface of the cooling channel is provided with a plurality of holes, and an electromagnet II is installed inside the cooling channel, wherein the pushing end of the electromagnet II is connected to an opening adjustment unit.

[0013] A further technical improvement of the present invention is that: the opening adjustment unit includes multiple blocking plates, a connecting plate is installed between two adjacent blocking plates, and the surface of the blocking plate is provided with a flow hole, which is arranged adjacent to the channel.

[0014] A further technical improvement of the present invention is that: the upper and lower end faces of the plurality of blocking plates are connected to a sliding plate, and the sliding plate is slidably disposed with the cooling channel.

[0015] A further technical improvement of the present invention is that: an air intake duct is provided on one side of the box, and an exhaust duct is provided on the other side of the box, and an organic cabinet door is rotatably installed on one side of the box.

[0016] A further technical improvement of the present invention is that a circulating water tank is installed on the bottom surface of the inner cavity of the box body, and the liquid inlet of the circulating water tank is connected to the liquid outlet of the cooling jacket through a return pipe.

[0017] The circulating water tank is provided with a cooling chamber 1 and a cooling chamber 2 in sequence, and the cooling chamber 1 and the cooling chamber 2 are connected by an exchange channel.

[0018] One side of the second cooling chamber is connected to the inlet of the cooling channel through the outlet of its internal water pump, and the outlet of the cooling jacket is connected to the first cooling chamber.

[0019] A solenoid valve is embedded in the exchange channel.

[0020] A further technical improvement of the present invention is that: the front end of the bearing limiting seat is open and the rear end is closed, the upper surface of the bearing limiting seat is provided with a sliding cavity, and a limiting member is provided inside the sliding cavity for lifting and lowering;

[0021] The inner wall of the housing is equipped with a linear guide rail, which is slidably connected to the load-bearing limiting seat.

[0022] A further technical improvement of the present invention is that: the limiting member includes an electromagnet, wherein the armature inside the electromagnet is connected to a fitting clamping block that slides within the sliding cavity via a connecting rod;

[0023] The upper surface of the fitting clamp is inclined, and one side of the fitting clamp is provided with a fitting part that blocks the mounting plate.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. By setting a cooling jacket, the airbags on both sides are in a deflated state. The cooling channel pulls the contact parts back by internal tension, and the telescopic part is in an extended and open state. The opening of the cooling jacket is enlarged, making it easy to put on the cooling jacket. This open structure can easily cover each heating module and is compatible with different specifications of working elements or working modules on the market. After the cooling jacket is installed, the air pump starts and inflates the airbags. The airbags gradually expand and push the contact parts connected to them toward the working element. The contact parts contract through the telescopic part, and the inner wall of the cooling jacket is in close contact with the surface of the working element, forming a tight contact state. This improves the heat transfer efficiency and ensures that the coolant inside the jacket has a good thermal conductivity surface fit in the heat transfer path. The cooling medium completes heat exchange between the contact parts and the heating elements, dynamically fitting the heating surface of the working elements and working modules. This avoids the problem of uneven local cooling caused by poor contact in traditional air cooling and improves the cooling heat transfer efficiency.

[0026] 2. By setting up an opening adjustment unit, the system monitors the temperature control information of the corresponding working element or module in real time and sends a temperature control signal. The temperature control signal triggers the electromagnet corresponding to that area. The electromagnet drives the sliding plate connected to its push end to slide along the longitudinal direction of the cooling channel. The sliding plate, in conjunction with multiple blocking plates, causes the position of the flow holes on two adjacent blocking plates to move. The flow holes, which were originally misaligned with the cooling channel channels, are aligned, switching the outlet path of the coolant or cooling gas from a semi-closed state to an open state. When the channel and the flow hole are aligned, the open area of ​​the cooling channel in that area expands. More cooling medium flows into the target cooling jacket. At the same time, the tight fit inside the jacket caused by the expansion of the airbag enhances the heat exchange efficiency between the contact parts and the working elements, ensuring that the high-temperature area receives rapid, directional, and locally enhanced cooling compensation. After the temperature drops to the preset safe range, the system controls the electromagnet to de-energize, and the sliding plate resets under the action of the preset elastic element, causing the flow hole to re-misalign with the channel, reducing the flow rate, supplying cooling on demand, avoiding energy waste and over-cooling, enhancing the system's temperature control accuracy and energy efficiency ratio, achieving rapid response to thermal loads at specific locations, and preventing the accumulation of local hot spots in the system.

[0027] 3. During the insertion process, the load-bearing limiting seat slides horizontally to the front of the housing, and the four ends of the mounting plate slide along the corresponding load-bearing limiting seat. The fitting clamp automatically moves out of position under the pressure of the inclined surface inside the sliding cavity. The fitting part of the fitting clamp forms a pressing limit with the side wall of the mounting plate. Then, the load-bearing limiting seat is slid to the depth of the housing cavity, avoiding insertion operations in narrow spaces deep inside the housing, reducing the difficulty of operation and improving assembly efficiency.

Detailed Implementation

[0036] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0037] Please see Figures 1-6As shown, the present invention provides an automatic temperature-controlled server chassis, including a chassis 1. A sliding limiting unit is installed on the inner wall of the chassis 1. The sliding limiting unit includes a load limiting seat 5 that slides horizontally along the inner wall of the chassis 1. Four load limiting seats 5 are provided. The same mounting plate 14 is snapped into the four load limiting seats 5. A power module and a storage module are installed inside the chassis 1.

[0038] The power module and the storage module together form the working module. The working module and the working components on the mounting plate 14 are all fitted with cooling jackets 19 for water cooling.

[0039] The cooling jacket 19 has airbag components 15 connected to the air pump via pipes on both sides of its interior. Each airbag component 15 has a heat conduction channel 16 connected to its inner end. The end of the heat conduction channel 16 is connected to a contact component 17 that contacts the working module or working element. Both ends of the contact component 17 have telescopic parts 18, and the contact component 17 is located on the inner wall surface of the cooling jacket 19.

[0040] Cooling jacket 19 is connected to a cooling channel 20 at one end. The outlet end of the cooling channel 20 is connected to the inlet end of the heat conduction channel 16 to circulate and deliver coolant into the cooling jacket 19.

[0041] During use, the load-bearing limiting seat 5 slides horizontally to the front end position inside the housing 1 to facilitate the installation of the mounting plate 14. When positioning the mounting plate 14, the four end faces of the mounting plate 14 are inserted by the load-bearing limiting seat 5 and locked in the end position. Then, the load-bearing limiting seat 5 slides horizontally close to the end of the inner cavity of the housing 1.

[0042] The power module (power supply) and storage module (hard disk) in the housing 1 are installed in their respective positions. The mounting plate 14 is equipped with working components such as CPU and GPU. Cooling jackets 19 of different shapes are fitted to the outside of the working components and working modules.

[0043] In the initial state, the airbag components 15 on both sides are in a deflated state. The heat conduction channel 16 pulls the contact component 17 back by internal tension, that is, it is squeezed and moved away from the component. At this time, the telescopic part 18 is in an extended and open state. That is, the cooling jacket 19 automatically unfolds to form an opening during installation, which improves the convenience of on-site assembly. At this time, the opening of the cooling jacket 19 is enlarged, which makes it easier to put the cooling jacket 19 on. Through this opening structure, each heat-generating module can be easily covered, which is compatible with different specifications of CPUs, GPUs and working modules on the market, enhancing equipment compatibility. When disassembling, the airbag component 15 deflates and automatically returns to its original shape, without affecting the layout and space planning of the chassis.

[0044] After the cooling jacket 19 is installed, the air pump is started to inflate the airbag 15. The airbag 15 gradually expands, pushing the contact 17 connected to it to squeeze and move towards the working element. The contact 17 contracts through the telescopic part 18, and the inner wall of the cooling jacket 19 is in close contact with the surface of the working element, thereby improving the heat transfer efficiency and ensuring that the coolant inside the jacket has good thermal conductivity and fit on the heat transfer path. The cooling medium completes heat exchange between the contact 17 and the heating element.

[0045] The internal cooling channel 20 provides circulating coolant, which passes through the heat conduction channel 16 to the contact element 17 in sequence, and heat exchange is completed at the contact surface.

[0046] By using the airbag components 15 on both sides to push the contact components 17 to dynamically fit the heating surface of the working element and the working module, the problem of uneven local cooling caused by poor contact in traditional air cooling is avoided, thereby improving the cooling and heat transfer efficiency.

[0047] It adopts a water-cooled and air pressure-regulated fanless forced convection structure to reduce system operating noise and improve energy efficiency ratio under precise heat dissipation control.

[0048] See Figure 6 As shown, the surface of the cooling channel 20 is provided with several holes 23, and an electromagnet 21 is installed inside the cooling channel 20. The pushing end of the electromagnet 21 is connected to an opening adjustment unit.

[0049] The opening adjustment unit includes multiple blocking plates 24, and a connecting plate 26 is installed between two adjacent blocking plates 24. The surface of the blocking plate 24 is provided with a flow hole 25, and the flow hole 25 is arranged adjacent to the channel 23.

[0050] Multiple blocking plates 24 have a sliding plate 22 connected to their upper and lower end faces. The sliding plate 22 is slidably disposed with the cooling channel 20.

[0051] An air intake duct 2 is provided on one side of the enclosure 1, and an exhaust duct 3 is provided on the other side of the enclosure 1. A cabinet door is installed on one side of the enclosure 1. The exhaust duct 3 and the air intake duct 2 assist the natural convection inside the enclosure to further balance the heat distribution.

[0052] Temperature sensors are installed on all working elements and working modules. The system continuously monitors heat distribution through the temperature sensors installed on each working element.

[0053] When the system detects an abnormally high temperature in a certain area inside the server chassis (such as an increase in the thermal load of the GPU or power module), i.e. the temperature value exceeds the set threshold, the system determines that the area needs to be cooled more effectively and sends a temperature control signal to the system.

[0054] The temperature control signal triggers the electromagnet 21 corresponding to the area. The electromagnet 21 drives the sliding plate 22 connected to its push end to slide along the longitudinal direction of the cooling channel 20. The sliding plate 22 is linked with multiple blocking plates 24, causing the position of the flow holes 25 on two adjacent blocking plates 24 to move. The flow holes 25 that were originally misaligned with the channel 23 are aligned, so that the outlet path of the coolant is switched from a semi-closed state to an open state. When the channel 23 is aligned with the flow holes 25, the open area of ​​the cooling channel 20 in this area is expanded, and more cooling medium flows into the target cooling jacket 19. At the same time, the tight fit inside the jacket caused by the expansion of the airbag 15 enhances the heat exchange efficiency between the contact 17 and the working element, ensuring that the high temperature area receives rapid, directional, and locally enhanced cooling compensation.

[0055] Once the temperature drops to the preset safe range, the system controls the electromagnet 21 to de-energize, and the sliding plate 22 resets under the action of the preset elastic element, causing the flow hole 25 to re-align with the channel 23, reducing the flow rate, providing cooling on demand, avoiding energy waste and over-cooling, enhancing the system's temperature control accuracy and energy efficiency ratio, achieving rapid response to thermal loads at specific locations, and preventing the accumulation of local hot spots in the system.

[0056] See Figure 1 and Figure 4 As shown, a circulating water tank 4 is installed on the bottom surface of the inner cavity of the box 1. The inlet end of the circulating water tank 4 is connected to the outlet end of the cooling jacket 19 through a return pipe.

[0057] The circulating water tank 4 is provided with a cooling chamber 1 9 and a cooling chamber 2 10 in sequence. A connecting exchange channel 11 is provided between the cooling chamber 1 9 and the cooling chamber 2 10. One side of the cooling chamber 2 10 is connected to the inlet of the cooling channel 20 through the outlet of its internal water pump. The outlet of the cooling jacket 19 is connected to the cooling chamber 1 9.

[0058] A solenoid valve is embedded in the exchange channel 11;

[0059] After the cooling jacket 19 absorbs the heat of the corresponding working element or working module during operation, its outlet end introduces the heated coolant into the cooling chamber 9 of the circulating water tank 4 through the return pipe. The cooling chamber 9 serves as the initial collection chamber for the heated liquid, accommodating all the return liquid from the cooling jacket 19.

[0060] Coolant enters cooling chamber 10 from cooling chamber 1-9 via exchange channel 11 located between the chambers. The system controls the opening degree of the solenoid valve according to the water temperature to adjust the flow rate between the two chambers, thereby controlling the residence time and cooling efficiency of the coolant. When the return fluid temperature is high, the solenoid valve opening time is extended to accelerate the flow. When the temperature is moderate, the solenoid valve operates at a throttling rate to increase the heat dissipation time of cooling chamber 1-9. After completing one cycle, the coolant returns to cooling chamber 1-9 via the outlet of cooling jacket 19. The entire system forms a dynamic closed-loop cooling path and achieves differentiated cooling control for different heat source areas with the help of temperature control sensors and electromagnetic flow control devices.

[0061] See Figure 2 and Figure 3 As shown, the front end of the bearing limiting seat 5 is open and the rear end is closed, forming a stop structure on the tail end of the mounting plate 14 to prevent excessive pushing. The upper surface of the bearing limiting seat 5 is provided with a sliding cavity 13, and the sliding cavity 13 is provided with a limiting component that moves up and down.

[0062] Linear guide rail 7 is installed on the inner wall of housing 1, and the linear guide rail 7 is slidably connected to the load-bearing limiting seat 5.

[0063] The limiting component includes an electromagnet 12, and the armature inside the electromagnet 12 is connected to a fitting clamp 6 that slides within the sliding cavity 13 via a connecting rod.

[0064] The upper surface of the clamping block 6 is inclined, and one side of the clamping block 6 is provided with a clamping part 8 that blocks the mounting plate 14.

[0065] The load-bearing limiting seat 5 is slid horizontally to the front side of the housing 1, and then the mounting plate 14 with the CPU and GPU installed is inserted through the front end of the opening of the load-bearing limiting seat 5. The four ends of the mounting plate 14 slide and push in along the corresponding interior of the load-bearing limiting seat 5.

[0066] During the insertion process, since the electromagnet 12 is de-energized, the internal armature does not push, and the connecting rod-driven clamping block 6 is in the sinking return state. At this time, the clamping block 6 automatically makes way along the inclined surface in the sliding cavity 13 to provide space for the insertion of the mounting plate 14.

[0067] The mounting plate 14 continues to slide backward until its four edge faces are in contact with the rear closed stop structure of the bearing limiting seat 5, at which point the initial positioning of the mounting plate 14 is completed.

[0068] The control system energizes and resets the electromagnet 12, and the armature drives the connecting rod to push the clamping block 6 upward, so that the clamping part 8 of the clamping block 6 forms a pressing limit with the side wall of the mounting plate 14, thereby realizing the anti-vibration limit and stable installation of the mounting plate 14 during server operation.

[0069] When disassembling and repairing the mounting plate 14, the system controls the electromagnet 12 to be energized again and reversed, causing the clamping block 6 to descend back into position in the sliding cavity 13, releasing the lateral restriction on the mounting plate 14, and allowing the user to smoothly pull out the mounting plate 14 from the front end.

[0070] In use, this invention features a cooling jacket 19. With the airbags 15 on both sides in a deflated state, the heat conduction channel 16 pulls the contact piece 17 back under internal tension, causing the telescopic part 18 to extend and open. This enlarges the opening of the cooling jacket 19, facilitating its installation. This open structure easily covers various heating modules, adapting to different specifications of working elements or modules available on the market. After installing the cooling jacket 19, the air pump starts, inflating the airbags 15. The airbags 15 gradually expand, pushing... The contact 17 connected to it is pressed and moved towards the working element. The contact 17 is contracted through the telescopic part 18. The inner wall of the cooling jacket 19 is in close contact with the surface of the working element, thereby improving the heat transfer efficiency and ensuring that the coolant inside the jacket has good thermal conductivity on the heat transfer path. The cooling medium completes heat exchange between the contact 17 and the heating element, dynamically fitting the heating surface of the working element and the working module, avoiding the problem of uneven local cooling caused by poor contact in traditional air cooling, and improving the cooling heat transfer efficiency.

[0071] By setting up an opening adjustment unit, the system monitors the temperature control information of the corresponding working element or module in real time and sends a temperature control signal. The temperature control signal triggers the electromagnet 21 corresponding to that area. The electromagnet 21 drives the sliding plate 22 connected to its pushing end to slide along the longitudinal direction of the cooling channel 20. The sliding plate 22 is linked with multiple blocking plates 24, causing the position of the flow holes 25 on two adjacent blocking plates 24 to move. The flow holes 25, which were originally misaligned with the channel 23, are aligned, and the coolant outlet path is switched from a semi-closed state to an open state. When the channel 23 and the flow hole 25 are aligned, the open area of ​​the cooling channel 20 in that area is expanded. More cooling medium flows into the target cooling jacket 19. At the same time, the tight fit inside the jacket caused by the expansion of the airbag 15 enhances the heat exchange efficiency between the contact 17 and the working element, ensuring that the high-temperature area receives rapid, directional, and locally enhanced cooling compensation. After the temperature drops to the preset safe range, the system controls the electromagnet 21 to be de-energized, and the sliding plate 22 is reset under the action of the preset elastic element, so that the flow hole 25 is repositioned with the channel 23, reducing the flow rate, supplying cooling on demand, avoiding energy waste and over-cooling, enhancing the system temperature control accuracy and energy efficiency ratio, realizing rapid response to heat load at specific locations, and preventing the accumulation of local hot spots in the system.

[0072] During insertion, the bearing limiting seat 5 slides horizontally to the front of the housing 1, and the four ends of the mounting plate 14 slide and advance along the corresponding interior of the bearing limiting seat 5. The fitting clamp 6 automatically yields under the pressure of the inclined surface inside the sliding cavity 13, providing space for the insertion of the mounting plate 14. The mounting plate 14 continues to slide backward until its four edge end faces respectively fit and contact the rear end closed stop structure of the bearing limiting seat 5. At this time, the initial positioning of the mounting plate 14 is completed. The control system energizes and resets the electromagnet 12, and the armature drives the connecting rod to push the fitting clamp 6 upward, so that the fitting part 8 of the fitting clamp 6 forms a pressing limit with the side wall of the mounting plate 14, thereby realizing the anti-vibration limit and stable installation of the mounting plate 14 during server operation. Then, the bearing limiting seat 5 is slid deep into the interior cavity of the housing 1 to avoid insertion operations in narrow spaces deep in the housing 1, reduce the difficulty of operation, and improve assembly efficiency.
