Description

Technical Field

[0001] The present invention relates to the field of computer technology, and more specifically to a military portable ruggedized phase change immersion liquid cooling all-in-one machine. Background Art

[0002] The development trend of informatization and intelligence of military equipment has put forward higher performance requirements for computers. Without breakthroughs in chip manufacturing processes, the heat generation power and heat flux density of domestic chips have further increased, forcing the heat dissipation capacity of domestic military computing equipment to reach a higher level. However, traditional air cooling technology has been stretched thin in the face of high heat flux density scenarios, and the heat dissipation intensity has reached its limit. Therefore, there is an urgent need to introduce a new heat dissipation method in the military ruggedized field. Summary of the Invention

[0003] The technical task of the present invention is to address the above deficiencies by providing a military portable ruggedized phase change immersion liquid cooling all-in-one machine, which can solve the problems of poor heat dissipation capacity of traditional air-cooled ruggedized computers and the adaptability and portability of conventional immersion liquid cooling in ruggedized scenarios in the military ruggedized field and conventional spaces.

[0004] The technical solution adopted by the present invention to solve its technical problems is as follows:

[0005] A military portable ruggedized phase change immersion liquid cooling all-in-one machine includes a display screen, a keyboard, an integrated chassis, a phase change circulation system, a liquid surface damping device, a liquid storage chamber, a gas storage chamber, an air cooling circulation system, and an automatic monitoring system;

[0006] Among them, the liquid surface damping device includes a plurality of impedance plates for left and right separation, a gas distribution plate with an inclined top, and a crossbeam for support and fixation; the impedance plates and the gas distribution plate divide the liquid cooling chassis into a plurality of uniformly sized units. When the chassis vibrates, since the liquid surface is divided into small units, the liquid surface can elastically contract and expand within a limited range, thereby reducing the impact of liquid surface vibration on the main board components.

[0007] Liquid level balance holes are uniformly distributed on the impedance plates to ensure that the liquid level height of the entire chassis is consistent;

[0008] The gas distribution plate is provided with air outlet holes and air caps. When the temperature of the heat generating components on the main board gradually rises and heats the coolant to the boiling point temperature, high-temperature gas is generated by the vaporization of the coolant on the surface of the heat generating components. When the gas leaves the liquid surface and rises, it reaches the manifold condenser through the air outlet holes on the gas distribution plate for condensation; the condensed coolant drips on the gas distribution plate, and the air caps are used to prevent the liquid from directly dripping and flowing through the air holes to avoid blocking the air holes.

[0009] Furthermore, the impedance plate is a rubber impedance plate. The impedance plate made of rubber effectively protects and buffers the chassis on the premise of minimizing the weight of the chassis, enabling the chassis to have the ability to resist vibration and shock and adaptability to complex scenarios.

[0010] Furthermore, the branch pipelines of the manifold condenser adopt integral low-finned tubes.

[0011] The coolant condensed on the surface of the fin is affected by the surface tension on the fin peaks, and its thickness is thinned and contracted into the gap between two fins. The integrally arranged low-finned tubes arranged obliquely use the action of gravity to gather the condensed coolant together and drip downward.

[0012] The fins of the integral low-finned tubes timely drain the condensed liquid generated on the surface while thinning the liquid film thickness, strengthening film condensation.

[0013] Furthermore, the manifold condenser is located in the upper space of the integrated chassis, and includes an intermediate pipeline, low-finned tubes on both sides, return pipelines on both sides, and a main return pipeline.

[0014] The intermediate pipeline is a liquid inlet pipeline. The low-temperature cooling working medium is evenly distributed to the low-finned tubes on both sides after passing through the intermediate pipeline, absorbs heat and then converges to the return pipelines on both sides. The return pipelines on both sides converge the cooled working medium after heat absorption into the main return pipeline and send it into the air-cooled radiator on the right side of the chassis.

[0015] The intermediate pipeline and the return pipelines on both sides are connected by integrally arranged low-finned tubes arranged obliquely; a tube-fin cross-flow heat exchanger with 1 shell pass and 2 tube passes is adopted in the air-cooled radiator on the right side. The fan is located on the main panel side of the chassis and blows in a blowing form. The overall flow mode of the coolant in the pipeline is U-shaped; the cooled coolant is pumped into the intermediate liquid inlet pipeline through a circulation pump.

[0016] Furthermore, the air cap is a spherical air cap one-third above the air hole.

[0017] The gas distribution plate is arranged with a higher middle and lower sides on both sides. This arrangement is used to accelerate the discharge of the dripping condensate to the liquid levels on both sides, thereby forming two non-interfering gas paths and liquid paths, improving the stability of the phase change cycle.

[0018] Furthermore, a liquid storage chamber and a gas storage chamber are respectively arranged at the upper and lower parts on the left side of the integrated chassis. A bellows and a vacuum switch are arranged in the gas storage chamber; the right side of the chassis is an air-cooled heat dissipation chamber.

[0019] Furthermore, a keyboard and a touchpad are arranged on the top of the integrated chassis. The surface of the middle chassis where the keyboard and the touchpad are located is flush with the upper surfaces of the chassis on both sides.

[0020] The display screen is connected to the all-in-one chassis by a hinge. Five magnetic attractions are evenly arranged above and on both sides of the display screen, so that the display screen is closely attached to the all-in-one chassis box in the closed state;

[0021] A portable handle is provided in the middle of the all-in-one chassis, and a window is provided at the lower part. The internal liquid level height and the circulating operation condition can be observed through the window.

[0022] Furthermore, a liquid level monitoring system is provided inside the all-in-one chassis. The liquid level monitoring system is used to open the automatic liquid replenishing device when the liquid level is lower than the safety threshold. The coolant flows out from the liquid storage chamber and is automatically replenished into the chassis. When the liquid level reaches the safety value, the liquid replenishment stops;

[0023] The liquid level monitoring system monitors the boiling point inside the chassis and the inlet liquid temperature of the circulating pump. When the boiling point temperature and the inlet liquid temperature of the circulating pump are too high, the rotational speeds of the circulating pump and the fan in the air-cooled circulation system increase from 50% of the rated operating speed to the rated operating speed.

[0024] Furthermore, a sensor for monitoring the internal pressure is also provided inside the all-in-one chassis. When the pressure is too high, the vacuum switch is turned on, and the gas inside the chassis enters the bellows of the gas storage chamber to maintain pressure balance.

[0025] Furthermore, the process of the all-in-one machine for cooling is as follows:

[0026] The heating elements immersed in the coolant in the all-in-one chassis heat up. When the temperature of the coolant rises to the saturation temperature at the corresponding pressure, the coolant vaporizes and evaporates. The vaporized coolant reaches the surface of the integral low-finned tubes of the manifold condenser through the air outlet holes in the gas distribution plate and condenses into a liquid; ribs for thinning the liquid film layer are evenly distributed on the integral low-finned tubes. The condensed coolant drips downward while converging to the gas distribution plate. A spherical air cap is provided above the air outlet hole. The condensed coolant does not pass through the air outlet hole but converges along the upper surface of the gas distribution plate into the lower liquid area;

[0027] In the manifold condenser, the low-temperature cooling working medium is pumped to the main inlet pipe by the circulating pump, evenly distributed into the integral low-finned tubes by the main inlet pipe, and the cooled working medium after absorbing heat converges into the main return pipe and enters the air-cooled radiator to be cooled;

[0028] A liquid level detection system is provided inside the chassis. When the internal phase-change coolant is lower than the safety threshold, the automatic liquid replenishing function can be turned on; a temperature detection system is provided at the inlet of the circulating pump to monitor the inlet liquid temperature of the pump in real time and write it into the BMC management information. The PWM speed regulation mechanism is integrated into the system to perform secondary regulation on the circulating pump and the fan according to the system operation condition; pressure monitoring points are provided inside the chassis. When the internal pressure of the chassis exceeds the safety threshold, the bellows vacuum valve is opened to relieve pressure.

[0029] Compared with the prior art, the military portable reinforced phase change immersion liquid cooling all-in-one machine of the present invention has the following beneficial effects:

[0030] 1. It has reinforced environmental adaptability. A liquid surface damping device is arranged inside the chassis. The impedance plates arranged on the left and right can effectively weaken the impact of liquid surface vibration on the main board devices, and the gas distribution plate can inhibit the up and down movement of the liquid surface and enhance the stability of the liquid surface.

[0031] 2. The manifold condenser can increase the condensation area. The integral low-finned tube structure of the branch pipeline can further thin the condensate film under the action of surface tension. The existence of a certain inclination angle will promote the discharge of the condensate and strengthen the condensation heat transfer; the inclined gas distribution plate will divert the dripping condensate to the liquid surface, forming non-interfering gas and liquid paths.

[0032] 3. It has an automatic monitoring and feedback mechanism to monitor the liquid level height and has the function of automatically replenishing liquid when the liquid level is low; it monitors the air pressure and has the ability to automatically reduce the pressure when the internal pressure exceeds the safety threshold; it monitors the internal temperature and the inlet liquid temperature to solve the problem of heat accumulation caused by the sudden increase in power at wide temperatures.

[0038] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0039] Compared with the civilian fields where phase change immersion liquid cooling is currently used, the military reinforced environment must not only ensure that the heat generated by high power consumption is dissipated in time, but also consider the requirements of vibration and shock resistance, adaptability to complex scenarios and portability.

[0040] The embodiment of the present invention provides a military portable reinforced phase change immersion liquid cooling integrated machine, referring to Figures 1 - 3 As shown, it includes a display screen 4, a keyboard 5, a chassis 1, a phase change circulation system, a liquid surface vibration reduction device, a liquid storage chamber 12, an air storage chamber 13, an air cooling circulation system and an automatic monitoring system.

[0041] Among them, the liquid level vibration reduction device includes a plurality of rubber impedance plates 16 for left and right separation, a gas distribution plate 17 inclined at the top, and a crossbeam 162 for support and fixation. The rubber impedance plates 16 and the gas distribution plates 17 divide the liquid-cooled chassis into a plurality of units of uniform size. When the chassis vibrates, the liquid surface is divided into small units, so that the liquid surface can be elastically contracted and stretched within a limited range, thereby effectively reducing the impact of the liquid surface vibration on the mainboard components. There are evenly distributed interconnected liquid level balance holes 161 on the rubber impedance plate 16 to ensure that the liquid level height of the entire chassis is consistent. The rubber wave-blocking plate effectively protects and cushions the chassis while reducing the weight of the chassis as much as possible, so that the chassis has the ability to resist vibration and shock and adapt to complex scenarios.

[0042] The gas distribution plate 17 is provided with an air outlet 171 and a spherical gas cap 172. When the temperature of the heating element on the main board gradually rises and the coolant is heated to the boiling point, the coolant on the surface of the heating element vaporizes to generate high-temperature gas. When the gas leaves the liquid surface and rises, it passes through the air outlet 171 on the gas distribution plate to reach the manifold condenser 14 for condensation. The branch pipeline of the manifold condenser 14 adopts an integral low-fin tube. Since the coolant condensed on the surface of the fin is subjected to the surface tension on the fin peak, its thickness is reduced and shrunk to the gap between the two fins, and the inclined integral low-fin tube uses the action of gravity to gather the condensed coolant together and drip downward; the fins of the integral low-fin tube thin the thickness of the liquid film and discharge the condensed liquid generated on the surface in time to strengthen the film condensation. The dripping condensed coolant falls on the gas distribution plate 17, and the spherical gas cap 172 one-third above the pore is designed to prevent the liquid from directly dripping and flowing through the pore to avoid blocking the pore. The arrangement of the gas distribution plate with a high middle and low sides will accelerate the discharge of dripping condensate to the liquid surfaces on both sides, thereby forming two gas and liquid paths that do not interfere with each other, improving the stability of the phase change cycle.

[0043] The manifold condenser 14 is located in the upper space of the integrated chassis 1, and includes a middle pipeline, low-fin tubes on both sides, return pipelines on both sides, and a main return pipeline.

[0044] The middle pipeline is the main liquid inlet pipeline 141. After passing through the middle pipeline, the low-temperature cooling working fluid is evenly distributed to the overall low-finned tubes 142 on both sides. After absorbing heat, it converges to the return pipelines on both sides, and the return pipelines on both sides converge the cooled working fluid after heat absorption into the main return pipeline 143 and send it into the air-cooled radiator on the right side of the chassis 1.

[0045] The main liquid inlet pipeline 141 is connected to the return pipelines on both sides by using the integrally formed low-finned tubes 142 arranged obliquely; in the air-cooled radiator on the right side, a tube-fin cross-flow heat exchanger with 1 shell side pass and 2 tube side passes is used, and the fan is located on the main panel side of the chassis and blows in the form of blowing. The overall flow mode of the coolant in the pipeline is U-shaped; the cooled coolant is pumped into the main liquid inlet pipeline 141 through a circulation pump.

[0046] A keyboard 5 and a touchpad 3 are arranged on the top of the chassis 1, and the surface of the middle chassis where the keyboard 5 and the touchpad 3 are located is flush with the upper surfaces of the two side chassis.

[0047] A liquid storage chamber 12 and a gas storage chamber 13 are respectively arranged at the upper and lower parts on the left side of the chassis 1, and a bellows and a vacuum switch are arranged in the gas storage chamber 13; the right side of the chassis is an air-cooled heat dissipation chamber 6.

[0048] The display screen 4 is connected to the chassis 1 through a hinge, and five magnetic absorptions are evenly arranged above and on both sides of the display screen 4, so that the display screen is closely attached to the chassis body in the closed state.

[0049] A portable handle is arranged in the middle of the chassis 1, and a window 11 is arranged at the lower part, and the internal liquid level height and the circulating operation condition can be observed through the window 11.

[0050] A liquid level monitoring system is arranged in the chassis. The liquid level monitoring system is used to open the automatic liquid filling device when the liquid level is lower than the safety threshold, and the coolant flows out from the liquid storage chamber 12 and is automatically filled into the chassis. When the liquid level reaches the safety value, the liquid filling stops. The liquid level monitoring system monitors the boiling point inside the chassis and the inlet temperature of the circulation pump. When the boiling point temperature and the inlet temperature of the circulation pump are too high, the rotation speeds of the circulation pump and the fan in the air-cooled circulation system increase from 50% of the rated working speed to the rated working speed. In addition, a sensor for monitoring the internal pressure is arranged inside the chassis. When the pressure is too high, the vacuum switch is opened, and the gas inside the chassis enters the bellows of the gas storage chamber 13 to maintain pressure balance.

[0051] The process of realizing temperature reduction by this military portable ruggedized phase change immersion liquid cooling all-in-one machine is as follows:

[0052] In the chassis 1, the heating elements immersed in the coolant heat up. When the temperature of the coolant rises to the saturation temperature at the corresponding pressure, the coolant vaporizes and evaporates. The vaporized coolant reaches the surface of the integral low-finned tube 142 through the air holes 171 in the gas distribution plate 17 and condenses into a liquid. The integral low-finned tube 142 is evenly distributed with fins 1421 for thinning the liquid film layer. The condensed coolant drips downward while converging to the gas distribution plate 17. Since a spherical air cap 172 is provided above the air hole 171, the condensed coolant does not pass through the air hole 171 but converges along the upper surface of the gas distribution plate 17 into the lower liquid area.

[0053] In the manifold condenser 14, the low-temperature cooling working medium is pumped by a circulation pump to the main inlet pipe 141, and is evenly distributed into the integral low-finned tube 142 by the main inlet pipe 141. The cooling working medium after absorbing heat converges into the main return pipe 143 and enters the air-cooled radiator 6 to be cooled down.

[0054] A liquid level detection system is provided inside the chassis. When the internal phase-change coolant is lower than the safety threshold, the automatic liquid replenishment function can be activated; a temperature detection system is provided at the inlet of the circulation pump to monitor the inlet liquid temperature of the pump in real time and write it into the BMC management information. The PWM speed regulation mechanism is integrated into the system to perform secondary regulation on the circulation pump and the fan according to the system operation status; pressure monitoring points are provided inside the chassis. When the internal pressure of the chassis exceeds the safety threshold, the bellows vacuum valve opens to relieve pressure. The specific process is as Figure 4 shown.

[0055] Through the above specific implementation manners, those skilled in the art of the said technical field can easily implement the present invention. However, it should be understood that the present invention is not limited to the above specific implementation manners. Based on the disclosed implementation manners, those skilled in the art of the said technical field can arbitrarily combine different technical features to thus implement different technical solutions.

[0056] Except for the technical features described in the specification, the rest are known technologies to those skilled in the art.
