Description

Technical Field

[0001] This invention relates to the field of server heat dissipation technology, and in particular to a server heat dissipation control system and a server. Background Technology

[0002] During long-term high-load operation, the core heat-generating functional modules of the current server work continuously at high frequency, which generates a lot of waste heat. On the other hand, the internal components, fans and mechanical structures of the equipment will continuously generate regular mechanical vibrations.

[0003] Currently, most conventional servers rely on external fans for forced cooling or natural convection cooling within the chassis. External fans consume a lot of energy and generate a lot of noise during long-term operation, and the fans themselves are prone to failure due to aging, increasing equipment maintenance costs and failure rates. Natural convection cooling has extremely low heat exchange efficiency, and heat tends to accumulate inside the chassis and cannot be quickly dissipated. Core heat-generating components are in a high-temperature operating environment for a long time, which can easily lead to operational lag, reduced computing power, accelerated component aging, and severely shorten the service life. At the same time, some traditional servers rely on a single spring for rigid cushioning and shock absorption. The shock absorption mode is limited and can only weaken small, low-frequency vibrations. When faced with instantaneous impact loads during equipment operation, the shock absorption is prone to failure. Moreover, the single spring shock absorption has a fast rebound speed, which can easily cause equipment resonance, secondary bouncing, and hard impacts on components. Long-term vibration can easily cause loosening of internal wiring, poor contact of plug-ins, and displacement and damage to precision electronic components, affecting the stability and safety of server operation. Summary of the Invention

[0004] The present invention provides a server heat dissipation control system that solves the technical pain points of existing systems, such as poor buffering effect, high energy consumption, and poor compatibility between buffering and heat dissipation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: On one hand, the present invention provides a heat dissipation control system for a server, the system comprising: a host housing;

[0006] Multiple cylinders are symmetrically fixed in pairs on the inner wall of the main body housing, and pistons are movably embedded in the inner wall of each cylinder.

[0007] Multiple transmission links are fixedly mounted on one side of multiple pistons, and each of the multiple transmission links has a connecting seat fixedly mounted at one end;

[0008] Multiple support rods are hinged to the inner walls of multiple connecting seats, and the multiple support rods are in pairs, with a base hinged to one end of each pair of support rods;

[0009] A buffer plate is fixedly installed on one side of the two bases, and two heat-collecting sinks are opened on one side of the buffer plate;

[0010] The multiple pistons respectively divide the interior of the corresponding cylinder into independent front air chambers and rear air chambers, and the two air chambers are not connected to each other.

[0011] As a further improvement of the present invention: a spring is provided inside the plurality of cylinders, one end of the spring abutting against one side of the piston, and the other end of the spring being fixed to one side of the inner wall of the cylinder.

[0012] As a further improvement of the present invention: the plurality of cylinders are grouped in pairs, and the air chambers of the two groups of cylinders near the rear of the spring are connected by a first connecting pipe. A first guide pipe is installed on the outer surface of the two first connecting pipes, and the two first guide pipes are connected to an air bag through an air nozzle.

[0013] As a further improvement of the present invention: the front air chambers of the two sets of cylinders away from the spring are connected to a second connecting pipe, both of the second connecting pipes are connected to a second guide pipe, and the ends of the two second guide pipes are connected to an air collection box, forming an air exchange and conduction path between the cylinder and the air collection box.

[0014] As a further improvement of the present invention: a heat collection interlayer is provided in the middle of one side of the buffer plate, and inclined guide plates are fixedly installed inside the two heat collection troughs. Several inclined guide holes are provided on one side of the two heat collection troughs. The two heat collection troughs, together with the inclined guide plates, direct and collect heat into the heat collection interlayer.

[0015] As a further improvement of the present invention: the bottom of the heat collection jacket is connected to a connecting pipe, and a first one-way valve is installed on the outer surface of the connecting pipe. One end of the connecting pipe is installed on the top of the gas collection box. The first one-way valve only allows hot air inside the heat collection jacket to flow into the gas collection box in one direction, preventing hot air from flowing back.

[0016] As a further improvement of the present invention: the bottom of the gas collection box is connected to an exhaust pipe, and a second one-way valve is installed on the outer surface of the exhaust pipe. The second one-way valve only allows the hot gas inside the gas collection box to be discharged outward in one direction, so as to realize the directional discharge of hot gas without backflow.

[0017] As a further improvement of the present invention: the end of the exhaust pipe is connected to a flexible hose, which is provided through a through hole in the side wall of the main unit housing to directly discharge the high-temperature hot air inside to the outside of the equipment.

[0018] As a further improvement of the present invention: two gaskets are fixedly provided on one side of the buffer plate, and two mounting bases are fixedly provided on one side of the buffer plate, with two airbags respectively installed on the inner walls of the two mounting bases.

[0019] On the other hand, the present invention provides a server, which includes two mounting brackets and two heat-generating functional modules. The heat-generating functional modules are installed inside the mounting brackets and are equipped with the aforementioned heat dissipation control system, which synchronously completes passive heat dissipation and composite shock absorption protection through the vibration of the device itself.

[0020] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0021] This invention employs a dual composite vibration reduction mode combining spring mechanical energy storage buffering and airbag pressure damping energy dissipation. This effectively absorbs low-frequency operating vibrations and instantaneous external impact loads during server operation, slows spring rebound speed, and reduces equipment resonance, secondary bounce, and hard impacts on components. It significantly reduces vibration damage to the server's internal precision electronic components, circuits, and connectors, ensuring long-term structural stability and reliable operation. Furthermore, it eliminates the need for additional cooling motors, fans, and external power supplies, utilizing the mechanical vibrations generated by the server's own operation as the sole power source. The reciprocating motion of the piston creates a directional circulation air path with negative pressure intake and positive pressure exhaust. Combined with the heat collection sink and heat collection jacket, the high-temperature hot air inside the chassis is quickly collected and directly discharged. At the same time, room-temperature cold air is automatically introduced for heat exchange using the air pressure difference. The passive heat dissipation has extremely low energy consumption and high heat dissipation efficiency, effectively avoiding the problems of high temperature accumulation in the core heat-generating module, computing power decay, and premature aging of components. This invention integrates vibration reduction and heat dissipation into a deeply linked structure, reusing the same set of mechanical transmission structure to achieve secondary utilization of vibration energy. The heat dissipation and ventilation work are completed simultaneously during the vibration reduction process. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figure 1 - Figure 9 This invention provides a server heat dissipation control system, which includes: a host housing 1; multiple cylinders 2, symmetrically arranged in pairs on the inner wall of the host housing 1, and pistons 201 are movably embedded in the inner wall of each cylinder 2; multiple transmission rods 202, respectively fixedly arranged on one side of the multiple pistons 201, and a connecting seat 203 is fixedly arranged at one end of each transmission rod 202; multiple support rods 205, respectively hinged to the inner wall of the multiple connecting seats 203, and the multiple support rods 205 are arranged in pairs, with a base 206 hinged at one end of each pair of support rods 205; a buffer plate 207, fixedly arranged on one side of the two bases 206, and two heat-collecting grooves 3 are opened on one side of the buffer plate 207; the multiple pistons 201 respectively divide the interior of the corresponding cylinder 2 into independent front air chambers and rear air chambers, and the two air chambers are not connected to each other.

[0034] During use, the two heat-generating functional modules 102 corresponding to the server are installed inside the mounting bracket 101, with the bottom of the heat-generating functional modules 102 attached to the upper position of the corresponding buffer plate 207. During normal full-load operation, the heat-generating functional modules 102 continuously generate working heat, while the server's operating conditions continuously generate regular small mechanical vibrations. The vibration load directly and continuously acts on the surface of the buffer plate 207, driving the buffer plate 207 to make stable and regular up-and-down reciprocating motions inside the main unit housing 1. During the up-and-down movement of the buffer plate 207, a complete mechanical transmission link is formed through the base 206, support rod 205, connecting seat 203 and transmission link 202, which in turn synchronously drives each piston 201 to make precise reciprocating pushing, pulling and sliding motions inside the corresponding cylinder 2. Relying on the server's own working vibration as the only power input, without the need for additional motors, fans, electric control drives and external power supplies, it can synchronously provide a continuous and stable mechanical linkage power foundation for subsequent mechanical composite vibration reduction operations and passive forced cooling and ventilation operations, realizing integrated recovery and utilization of vibration energy, saving energy and reducing consumption.

[0035] Please see Figure 1 - Figure 9 In one embodiment, multiple cylinders 2 are provided with springs 204 inside. One end of the spring 204 abuts against one side of the piston 201, and the other end of the spring 204 is fixed to one side of the inner wall of the cylinder 2. The spring 204 serves as the primary buffer core and is mainly used to bear the hard vibration impact transmitted by the buffer plate 207. During the reciprocating sliding process of the piston 201, the spring 204 is continuously compressed and rebounded. The elastic deformation of the spring 204 absorbs most of the low-frequency vibration and working impact, effectively weakening the hard collision caused by rigid transmission, reducing the amplitude of the operating foundation vibration, ensuring the stable operation of the electronic components inside the server, and avoiding problems such as loosening of components, poor contact, and shortened service life caused by long-term vibration.

[0036] Please see Figure 1 - Figure 9In one embodiment, multiple cylinders 2 are grouped in pairs. The rear air chambers of the two groups of cylinders 2 near the spring 204 are connected by a first connecting pipe 209. A first guide pipe 210 is installed on the outer surface of each of the two first connecting pipes 209. Each of the two first guide pipes 210 is connected to an air bladder 212 through an air nozzle 211. The rear air chamber is specifically used as a shock-absorbing air pressure damping air passage. When the piston 201 is pressed down during the compression stroke, the volume of the rear air chamber decreases and the air pressure increases. The high-pressure gas passes through the first connecting pipe 209, the first guide pipe 210, and the air nozzle 212. 11 is pressed into the airbag 212, causing the airbag 212 to inflate and expand to form a flexible air pressure buffer damping, which, together with the spring 204, offsets the instantaneous impact load. When the piston 201 rebounds to its reset stroke, the volume of the rear air chamber increases, forming a negative pressure, which draws the gas inside the airbag 212 back. The airbag 212 then retracts and releases pressure, effectively slowing down the rapid rebound speed of the spring 204. From a structural principle perspective, this prevents the resonance, secondary bounce, and reciprocating shaking problems that are prone to occur with single spring shock absorption, and achieves a composite shock absorption and protection effect that combines mechanical spring buffering with air pressure damping.

[0037] Please see Figure 1 - Figure 9 In one embodiment, the front air chambers of the two sets of cylinders 2 away from the spring 204 are connected to a second connecting pipe 304. Both second connecting pipes 304 are connected to a second guide pipe 305. The ends of the two second guide pipes 305 are connected to a gas collection box 306, forming an air exchange conduction path between the cylinders 2 and the gas collection box 306. The front air chamber is used specifically as a working air path for heat dissipation and air exchange. The two second connecting pipes 304 are responsible for synchronizing the air pressure of the left and right cylinders 2, ensuring that the piston exchange action on both sides is consistent and the air pressure is balanced. The two second guide pipes 305 are symmetrically installed on both sides of the gas collection box 306 to conduct the negative pressure suction and positive pressure exhaust generated by the front air chamber, providing a stable air path channel for hot air extraction and collection and directional exhaust, ensuring that the heat dissipation airflow circulation is uniform and smooth, and there will be no situation of insufficient air pressure on one side of the air path or poor air extraction and exhaust.

[0038] Please see Figure 1 - Figure 9In one embodiment, a heat-collecting interlayer 302 is provided in the middle of one side of the buffer plate 207. An inclined guide plate 301 is fixedly installed inside each of the two heat-collecting sinks 3. Several inclined guide holes 303 are provided on one side of each of the two heat-collecting sinks 3. The two heat-collecting sinks 3, together with the inclined guide plates 301, direct and collect heat into the heat-collecting interlayer 302. The heat-collecting sinks 3 adopt a semi-enclosed tank structure design, which can effectively enclose and gather the working heat emitted downward by the heating function module 102, block the disorderly diffusion of heat inside the main unit housing 1, and avoid excessive overall temperature rise inside the chassis. With the inclined guiding effect of the inclined guide plate 301 and the unidirectional guiding effect of the inclined guide holes 303, the mixed hot air flow is directed and collected, and all of it is concentrated into the heat-collecting interlayer 302 to form a high-temperature accumulation area, avoiding inefficient heat dissipation and providing a stable heat source collection basis for subsequent centralized exhaust and heat dissipation.

[0039] Please see Figure 1 - Figure 9 In one embodiment, the bottom of the heat collection jacket 302 is connected to a connecting pipe 307. A first one-way valve 308 is installed on the outer surface of the connecting pipe 307. One end of the connecting pipe 307 is installed on the top of the gas collection box 306. The first one-way valve 308 only allows hot air inside the heat collection jacket 302 to flow into the gas collection box 306 in one direction to prevent hot air backflow. When the piston 201 is pulled back to form a negative pressure suction stage, the negative pressure suction opens the first one-way valve 308 and forces the high-temperature hot air inside the heat collection jacket 302 into the gas collection box 306 for temporary storage and collection. When the piston 201 is pushed forward to exhaust the gas, the first one-way valve 308 automatically closes to lock the air and prevents hot air from flowing back into the heat collection sink 3, ensuring that the airflow can only flow forward in one direction.

[0040] Please see Figure 1 - Figure 9 In one embodiment, the bottom of the gas collection box 306 is connected to an exhaust pipe 309. A second one-way valve 310 is installed on the outer surface of the exhaust pipe 309. The second one-way valve 310 only allows the hot gas inside the gas collection box 306 to be discharged outward in one direction, so as to realize the directional discharge of hot gas without backflow. When the piston 201 pushes forward to compress and generate positive pressure exhaust, the gas pressure inside the gas collection box 306 increases and opens the second one-way valve 310, pushing the collected high-temperature hot gas outward in a unified manner. During the negative pressure intake stage, the second one-way valve 310 automatically closes to prevent outside air from flowing back into the gas collection box 306. The two one-way valves cooperate in both directions to lock the air and control the flow, ensuring that the intake and exhaust strokes do not interfere with each other.

[0041] Please see Figure 1 - Figure 9In one embodiment, the end of the exhaust pipe 309 is connected to a flexible hose 311. The flexible hose 311 is provided through a through hole 312 opened in the side wall of the main unit housing 1 to directly discharge the high-temperature hot air inside to the outside of the equipment. The flexible hose 311 is flexible and can adapt to the internal vibration and structural displacement of the main unit housing 1, so as to directly lead the high-temperature hot air out of the equipment and avoid the hot air from flowing back into the chassis, thereby further improving the overall heat dissipation and cooling effect. It is worth noting that both the first guide pipe 210 and the second guide pipe 305 are flexible.

[0042] Please see Figure 1 - Figure 9 Figure 1 Figure 9 Figure 1 Figure 9 In one embodiment, two gaskets 208 are fixedly provided on one side of the buffer plate 207, and two mounting bases 213 are fixedly provided on one side of the buffer plate 207. Two airbags 212 are respectively installed on the inner walls of the two mounting bases 213. The gaskets 208 are used for buffer protection, noise reduction and vibration damping, to avoid the abnormal noise and wear caused by hard friction and collision between the heating function module 102 and the buffer plate 207. The mounting bases 213 are used to fix and limit the airbags 212, to prevent the airbags 212 from shifting, falling off and deforming during inflation and deflation, to ensure the stable operation of the airbags 212 during long-term repeated inflation and deflation, and to extend the service life of the overall shock absorption structure.

[0043] A server includes two mounting brackets 101 and two heat dissipation modules 102. The heat dissipation modules 102 are installed inside the mounting brackets 101 and are equipped with the aforementioned heat dissipation control system, which synchronously completes passive heat dissipation and composite shock absorption protection through the vibration of the device itself.

[0044] Working principle: During use, two heating function modules 102 are inserted into the two mounting brackets 101. At this time, the two heating function modules 102 are located on the upper side of the buffer plate 207. The two heating function modules 102 are the main working components during the operation of the server. During operation, they continuously generate working heat and generate regular mechanical vibrations. The vibration force directly acts on the buffer plate 207, causing the buffer plate 207 to move up and down regularly inside the host housing 1. During the downward pressing of the buffer plate 207, the force is transmitted to the two bases 206. The four support rods 205 are connected to the corresponding bases 206 in pairs. One end of the four support rods 205 is respectively hinged to the inner wall of the connecting seat 203. Then, when the buffer plate 207 moves up and down, the transmission connecting rod 202 drives the four pistons 201 to perform reciprocating pushing and sliding movements inside the corresponding cylinders 2, providing the overall mechanical power source for subsequent composite shock absorption and passive heat dissipation and ventilation.

[0045] Four pistons 201 reciprocate inside the cylinder 2 while compressing the corresponding springs 204. The basic mechanical buffering is achieved by the repeated compression and rebound of the springs 204. The two first connecting pipes 209 are respectively connected to the air chambers where the springs 204 are located in the two cylinders 2. The reciprocating motion of the pistons 201 inside the cylinder 2 generates air pressure changes. The air pressure is delivered to the two air bags 212 through the first connecting pipes 209 and the air nozzles 211, realizing the periodic inflation and deflation of the air bags 212. When the pistons 201 are pressed down, the air bags 212 inflate and form flexible air pressure damping buffers. Together with the mechanical compression of the four springs 204, they offset the hard impact. When the pistons 201 rebound and reset, a negative pressure is formed inside the cylinder 2, which draws the gas back from the air bags 212. The air bags 212 retract synchronously to release pressure, delaying the rebound speed of the springs 204 and avoiding resonance and secondary bouncing and collision of the equipment. The whole system forms a composite shock absorption and protection effect that combines mechanical spring buffering and air pressure air bag damping.

[0046] While the equipment operates with vibration damping, it simultaneously performs passive heat dissipation. Two heat-gathering troughs 3 are provided on the upper side of the buffer plate 207 corresponding to the position of the heating function module 102. The heat generated by the heating function module 102 sinks downward and adheres to the internal space of the heat-gathering trough 3. The heat-gathering trough 3 forms a semi-enclosed heat-gathering area through its enclosed structure, preventing the heat from spreading widely into the main housing 1. Combined with the inclined guide plate 301, the mixed hot air is directionally gathered and guided. All the high-temperature hot air after heat exchange flows through the inclined guide hole 303 and converges into the interior of the central heat-collecting jacket 302. Utilizing the unidirectional flow of the inclined channel and the enclosed temperature-locking structure of the trough, all the heat generated during operation is concentrated and collected in the interior of the heat-collecting jacket 302 to form a high-temperature accumulation area, avoiding disorderly heat dissipation and inefficient heat dissipation.

[0047] During the reciprocating sliding process of piston 201, alternating negative pressure for intake and positive pressure for exhaust are generated, achieving directional circulation of heat dissipation airflow. When piston 201 retracts during its backward stroke, it moves back towards the rear of cylinder 2, increasing the volume of the front air chamber inside cylinder 2. This reduces the internal air pressure and automatically creates a negative pressure vacuum. This negative pressure is simultaneously transmitted through the second connecting pipe 304 and the second guide pipe 305 to the inside of the gas collecting box 306, creating a negative pressure suction state inside the gas collecting box 306. Under the action of the negative pressure difference, the first one-way valve 308 automatically opens, thereby continuously and forcibly drawing the high-temperature hot air that has accumulated inside the heat collecting jacket 302 into the gas collecting box 306 for temporary storage via the connecting pipe 307, completing the collection and storage of hot air. When piston 201 pushes forward during the compression and exhaust stroke, the first one-way valve 308 automatically closes to prevent the hot air from flowing back. The hot air, pressurized inside the gas collection box 306, is discharged outward through the exhaust pipe 309. A second one-way valve 310 is installed on the outer surface of the exhaust pipe 309. The second one-way valve 310 only allows the hot air to flow outward in one direction. The hot air is finally discharged directly to the outside of the equipment through the through hole 312 on one side of the main unit housing 1 via the hose 311. Whenever the hot air is drawn away by negative pressure and discharged outward, the air pressure inside the heat collection tank 3 and the heat collection jacket 302 decreases accordingly, forming a pressure difference state where the internal air pressure is lower than the external atmospheric pressure. Under the action of atmospheric pressure, the ambient temperature cold air outside the equipment will be automatically pressed into the heat collection tank 3, continuously contacting and absorbing heat at the bottom of the heating function module 102. Without the need for an additional fan power drive, the cold air can be continuously and automatically replenished for circulation and heat dissipation. By relying on the vibration linkage of the equipment itself, the server can achieve stable composite vibration reduction and efficient passive heat dissipation and cooling.

[0048] Furthermore, to verify the feasibility, operational rationality, and practical application effect of the passive heat dissipation composite vibration reduction structure of this application, this application combines the normal full-load operation conditions of the server and conducts theoretical quantitative verification through three parts: theoretical derivation of mechanical motion airflow conversion, thermal resistance model analysis of heat accumulation and airflow circulation, and derivation of composite vibration reduction mechanical model.

[0049] Specifically, the theoretical derivation of mechanical motion and airflow conversion: In the preferred embodiment of this application, when the server is operating under high load or the internal fan is rotating at high speed, the heat dissipation module 102 continuously generates a frequency 50Hz, amplitude The buffer plate 207 exhibits a regular mechanical vibration of 0.5 mm. Its reciprocating motion is linked to the support rod 205 via a transmission link 202, synchronously transmitting power to drive the piston 201. Through the geometric transmission relationship of the linkage mechanism, the buffer plate 207 generates an amplitude. During the reciprocating motion, the piston 201 forms a theoretically effective reciprocating stroke inside the cylinder 2. It satisfies the calculation formula:

[0050]

[0051] in, For the effective reciprocating stroke of piston 201 inside cylinder 2, The amplitude generated by the buffer plate 207 The transmission ratio coefficient of the linkage mechanism is given by the following values: The value is 2, corresponding to the actual effective reciprocating stroke of piston 201. ;

[0052] Set the inner diameter of cylinder 2 The theoretical exhaust volume calculation formula for a single piston 201 in a single reciprocating stroke is:

[0053]

[0054] This device is equipped with four pistons 201 that work in a coordinated and synchronous manner. The movement frequency of the pistons 201 is synchronized with the vibration frequency of the equipment. The theoretical total air exchange volume of the system per minute is calculated using the following formula:

[0055]

[0056] Substituting the above structural parameters into the quantitative calculation, it can be seen that this device can continuously produce a stable circulating airflow simply by relying on the vibration of the equipment itself, without the need for additional motors, fans, or external power drives. The mechanical energy of mechanical vibration is directly converted into the kinetic energy of fluid flow, forming a directional, continuous, passive air exchange and heat dissipation cycle inside the equipment.

[0057] Specifically, the thermal resistance model analysis of heat accumulation and airflow circulation: To verify the heat exchange and cooling effect of the combined heat dissipation structure of the heat accumulation sink 3 and the heat collection jacket 302, this application introduces a thermodynamic thermal resistance model to conduct theoretical comparative analysis. The total heat generation power of the heat-generating functional module 102 and the total thermal resistance of heat dissipation to the outside are... Thermal resistance due to structural conduction Thermal resistance to heat transfer with air convection The composition satisfies the superposition relationship of thermal resistance:

[0058]

[0059] Traditional server enclosures rely solely on natural convection for cooling, resulting in low airflow velocity and low convective heat transfer coefficient. The size is relatively small, resulting in a large overall convective thermal resistance. This application utilizes the reciprocating suction action of piston 201 to create a directional forced heat transfer airflow within the heat-collecting sink 3. Based on Newton's law of cooling and heat transfer, the convective heat transfer thermal resistance satisfies...

[0060]

[0061] In conjunction with the inclined airflow guide plate 301, the forced airflow is directed to the core heating area at the bottom of the heating function module 102, effectively increasing the effective heat exchange area. Increase local airflow velocity and convective heat transfer coefficient This significantly reduces the system's convective heat transfer thermal resistance from a thermodynamic perspective.

[0062] Specifically, the mechanical model derivation of the shock absorption and buffering: The shock absorption system of this device is simplified into a shock absorption mechanical model coupled with spring mechanical energy storage and air pressure damping energy dissipation. When the equipment operates under vibration or external impact generates downward pressure, the shock absorption structure buffers and unloads the force in two stages.

[0063] The first stage is the mechanical buffering stage: the buffer plate 207 presses down on the linkage base 206 to compress the spring 204, and the spring 204 generates a linear elastic restoring force. ,satisfy

[0064]

[0065] in, The spring constant is... The spring is compressed and displaced in real time, and the energy stored by the elastic deformation of the spring is used to offset the server's normal low-frequency vibration and the hard impact load of the foundation.

[0066] The second stage is the pneumatic damping buffer stage: the piston 201 compresses synchronously with the vibration, forcing the gas in the cylinder 2's internal air chamber into the airbag 212. The airbag 212 inflates and expands, generating a nonlinear pneumatic damping force, which synchronously shares the impact load. When the piston 201 rebounds and resets to form a negative pressure for air extraction, the airbag 212 slowly contracts and releases pressure, generating a reverse hysteresis damping resistance, which effectively slows down the rebound speed of the spring 204 and avoids the resonance and secondary bounce problems that are prone to occur with single spring shock absorption.

[0067] In summary, through the theoretical derivation, thermal resistance model analysis, and mechanical model derivation of the above-mentioned mechanical motion and air volume conversion, the passive heat dissipation composite vibration reduction integrated structure of this application is adapted to the normal vibration frequency and amplitude working conditions of the server, stably generates effective heat dissipation circulation airflow, continuously reduces the working temperature of the core heat-generating components, and effectively attenuates the vibration amplitude of the equipment, without requiring additional power drive and electronic control.
