Definitions
- Cooling system for liquid immersion cooling of electronic components
- the invention relates to a cooling system for liquid immersion cooling of electronic components according to the preamble of claim 1.
- Liquid immersion cooling systems such as two-phase immersion cooling systems, are an efficient cooling solution for electronic components that generate a lot of heat during operation.
- a two-phase heat transfer fluid which preferably has a low boiling point
- the heat generated by the electronic component can evaporate the surrounding liquid heat transfer fluid, thereby removing heat from the electronic component.
- a condenser device liquefies the gaseous heat transfer fluid, which is then returned to the reservoir for cooling.
- a two-phase immersion cooling system with a cooling basin is known from the publication US 10 512 192 B2.
- a condensation chamber in which the gaseous fluid produced during the cooling process is condensed, is connected to the liquid fluid in the cooling basin.
- a vapor diversion structure is arranged above the heat-generating electronic components, which are located within the cooling medium in the cooling basin. The vaporized fluid is guided into the condensation chamber for liquefaction by means of the vapor diversion structure.
- the condensation chamber is located within the cooling basin.
- a two-phase immersion cooling system with an immersion tank and a primary condenser for gaseous heat transfer fluid is known.
- the primary condenser is in thermal connection with the internal volume of the immersion tank.
- the immersion cooling system also includes a vapor management system that is connected on the flow side to the head space of the immersion tank.
- the vapor management system makes it possible to effectively manage periods of high vapor production by removing fluid vapor and other gases from the head space of the immersion tank, condensing the vapor to liquid and returning the liquid to the immersion tank.
- a cooling system for computer components is known from the document US 10 477 726 B1.
- a pressure-controlled container contains a heat-conducting, dielectric heat transfer fluid in liquid and gaseous phases, which has a boiling point of less than 80°C at atmospheric pressure.
- Computer components are arranged in the container, which are at least partially immersed in the liquid phase of the heat transfer fluid.
- the dielectric gas phase fluid evaporated by the heat generated by the computer components is condensed into dielectric liquid phase fluid by means of a condenser.
- the internal pressure in the interior of the pressure-controlled container is reduced to as low as 650 hPa.
- By controlling the pressure in the container at which the system operates the user can influence the temperature at which the dielectric fluid evaporates. This can achieve increased cooling performance.
- the operation of a computer system within a pressure-controlled vessel at an operating pressure that deviates from the ambient pressure usually requires a structural adaptation of the system as a whole.
- Container known that uses two-phase heat transfer fluid as coolant can be filled, in the liquid phase of which electronic components can be immersed.
- the container has a gas space above the surface of the liquid heat transfer fluid.
- a separate external condenser device is arranged above the container, which is configured to condense the vapor phase of the heat transfer fluid and return it as a liquid coolant to the container with the electronic components.
- the system comprises return and supply lines that are connected to both the condenser device and the container to form a heat exchange loop.
- the system also includes a collecting vessel, which is arranged on the supply line and is configured to collect the condensed, liquid heat transfer fluid before the coolant is supplied to the container. This accumulator also provides reserve cooling capacity for the cooling system.
- a cooling system for immersion cooling of electronic components with a pressure-tight tank, configured to hold heat transfer fluid in liquid form, into which the electronic equipment is immersed.
- a vapor space is present above a surface of the liquid heat transfer fluid.
- a condenser is arranged outside the pressure-tight tank, wherein the condenser has an inlet which is connected to the vapor space by a riser pipe and is configured to receive heat transfer fluid vapor.
- the condenser has a tightly sealable vapor outlet for residual gases and a condensate outlet with a condensate return line to the tank.
- the condensate return line is designed such that condensed heat transfer fluid can flow back from the condensate outlet to the tank through it. Additional condenser tubes for liquefying gaseous heat transfer fluid can also be present within the tank.
- the invention is based on the object of developing a cooling system for liquid immersion cooling of electronic components with respect to a heat exchanger device.
- the invention includes a cooling system for liquid immersion cooling of electronic components.
- the cooling system comprises:
- a container which can be filled with a two-phase heat transfer fluid in the liquid phase of which electronic components can be immersed, the container having a gas space above the surface of the liquid heat transfer fluid,
- the condenser unit is in contact with the gas space of the container by means of at least one fluid inlet opening for the mass exchange of gaseous medium to the condenser unit or liquid medium from the condenser unit and the condenser unit has an outlet via which a residual gas phase can be discharged.
- the condenser unit has a tube bundle with heat exchanger tubes running parallel to one another in the axial direction in an enclosing housing downstream of the at least one fluid inlet opening in the flow direction, whereby a flow channel is formed in the housing. Furthermore, the tube bundle is arranged in the housing in such a way that gaseous medium flows in the flow channel along the axial direction of the heat exchanger tubes.
- the invention is based on the idea that the housing of the condenser unit with an internal tube bundle made of straight heat exchanger tubes running parallel to one another forms a kind of elongated cooling section in which gaseous heat transfer fluid originating from the container is cooled and liquefied.
- the heat transfer fluid condensed on the heat exchanger tubes drips onto the housing base, which preferably has a sufficient inclination from the horizontal in the direction of the fluid outlet opening so that the liquid heat transfer fluid flows back into the container through the fluid outlet opening.
- the condensation process constantly reduces the amount of gaseous heat transfer fluid so that a negative pressure is created in the housing of the condenser unit compared to the container. This means that gaseous heat transfer fluid constantly flows from the gas space of the container into the housing of the condenser unit through at least one fluid inlet opening.
- the system therefore regulates itself independently depending on the pressure and the heat transfer area.
- a condenser unit can also be individually designed in multiple versions, each at different positions inside or outside the container, depending on the cooling requirements.
- the particular advantage of the solution according to the invention is the particularly long cooling section formed by heat exchanger tubes, along which the gaseous fluid is forcibly guided inside an elongated housing.
- the container can be designed to be pressure-tight.
- the container can advantageously be designed as a pressure vessel that can be operated with a negative pressure and/or positive pressure. By controlling the pressure in the container at which the cooling system operates, an increased cooling capacity can be achieved.
- the heat exchanger device in the gas space preferably consists of at least one tube bundle formed from several heat exchanger tubes arranged parallel to one another.
- a tube bundle can have several heat exchanger tubes arranged parallel to one another with two end tube plates.
- the heat exchanger tubes are preferably finned tubes, which are made from smooth tubes and have been subjected to a forming process. They are particularly suitable as components in highly efficient, compact and extremely stable heat exchangers with a high heat transfer coefficient.
- the tube surfaces are optimized for the specific heat transfer requirements of the application. With a large selection of materials, which include copper, copper alloys, steels, titanium or titanium alloys, it is ensured that suitable material is available for different needs for the respective requirements, especially in terms of durability and formability.
- the two-phase heat transfer fluid also known as the refrigerant, is the external fluid in the container, in whose liquid part the electronic components are immersed.
- the internal fluid in the heat exchanger tubes is usually a single-phase heat transfer medium, for example process water, glycol or a thermal oil.
- a two-phase medium can also be used here in conjunction with a refrigeration circuit.
- the electronic components are arranged in a suitable manner in a bath of liquid heat transfer fluid, which is cooled by evaporation of the liquid fluid. In this way, the proportion of non-condensable gases can be effectively removed from the system before or during commissioning.
- the computing components and immersion cooling devices as well as the associated power supplies, network connections, wiring connections and the like can be arranged in the container, which has an internal pressure that differs from the ambient pressure during operation.
- the vessel is maintained during operation at up to 200 hPa less than ambient atmospheric pressure, which helps to lower the boiling point of the two-phase heat transfer fluid and thereby reduce the operating temperature of the computer chips and other components.
- the pressure-controlled vessel may be designed for an even lower pressure of up to 500 hPa below ambient pressure.
- Embodiments of the cooling system according to the invention comprise a container for dielectric cooling fluid, a heat exchanger device and a condenser unit for condensing the dielectric fluid from the gaseous phase to a liquid.
- the condenser unit located outside or inside the container is intended to condense the remainder of the gaseous heat transfer fluid, which also contains certain amounts of air and water vapor, into liquid heat transfer fluid to the greatest possible extent.
- the remaining heat transfer fluid is almost completely condensed from the gaseous phase, so that essentially only air and water vapor remain as the residual gas phase.
- the aim of the Separation of liquid heat transfer fluid involves keeping the water vapor in the gas phase by means of a suitable cooling capacity of the system. This residual gas mixture is discharged from the cooling system via an outlet of the condenser unit.
- means may be provided for holding computer components and distributing power from the power system to the devices and components located within the container. It will be appreciated that a variety of specialized connections may be used to operate a computer system within a container, for example, held at a vacuum. Some embodiments of the system of the invention may use a series of fiber optic interfaces to provide connectivity within the container and to distribute the fibers to the various holding devices to the electronic components. Some embodiments of the container may include monitoring sensors for safe operation. These sensors may include temperature sensors, fluid level sensors, pressure sensors, position sensors, electrical sensors and/or cameras to ensure and automate the operation of the system.
- These systems may, for example, include pressure sensors inside the pressure-controlled vessel that monitor the pressure to ensure that there are no significant leaks.
- gas sensors located on the outside of the pressure-controlled vessel may detect the presence of any dielectric vapor escaping from the pressure-controlled vessel.
- the cooling system can advantageously comprise a control device which is designed to control the operation of the fluid circulation, for example as Function to regulate the temperature of the two-phase heat transfer fluid and the pressure conditions in the vessel.
- the flow channel can vary in its passage cross-section for the fluid in the direction of flow. This measure is intended to concentrate the flow of the heat transfer fluid on the heat exchanger tubes running parallel to one another in the axial direction and prevent backflow.
- the flow channel can advantageously have a large number of chambers that are connected by connecting channels with a smaller passage cross-section. This leads to the gaseous heat transfer fluid being guided from chamber to chamber until liquefaction occurs. In this way, the residence time in the respective chambers is increased and the flow is controlled via the pressure gradient that occurs at the narrow points.
- the tube bundle with the heat exchanger tubes can be guided through the chambers and through the connecting channels in the flow channel. This measure is also intended to concentrate the flow of the heat transfer fluid on the heat exchanger tubes running parallel to one another in the axial direction and prevent backflow.
- guide structures for the gaseous fluid can be arranged.
- the steam is thus forced to flow along the heat exchanger surface of the tube bundle towards the outlet in order to condense as much coolant as possible.
- the condenser unit can be arranged inside or outside the container.
- the condenser unit is an independent module which only needs to be connected to the gas space of the vessel in any suitable manner for mass transfer of the fluid.
- a condenser unit arranged inside the container can be arranged above or next to the heat exchanger device in the gas space of the container.
- a gaseous fluid phase which is already enriched with residual gases, such as air components or water vapor, and is available for further condensation.
- a collecting container can be arranged downstream of the outlet of the condenser unit, through which the residual gas phase can be discharged. This container also ensures that no air from the environment can enter the cooling system.
- the container can be an expandable elastic balloon or a bellows with a variable volume.
- a drying unit for separating water vapor from the gas phase can be arranged between the outlet and the collecting container.
- the pressure level in the entire cooling system often changes when the load changes. If necessary, outside air or residual gas can be introduced into the cooling system via the collecting container via the drying unit to equalize the pressure.
- Silica gel which binds water vapor, is suitable for such drying units.
- a vacuum pump can be arranged downstream of the outlet, via which the residual gas phase can be discharged.
- the residual gas phase consisting of water vapor and air at the outlet can also have a negative pressure compared to the environment, since a vacuum pump always ensures that the residual gas flows outwards.
- the heat exchanger device and the condenser unit can have a common supply unit for a first single-phase heat transfer medium for cooling. Both units are thus at a uniform temperature level, which is suitable for the separation process of the heat exchanger fluid.
- the condenser unit can have a second supply unit for a second single-phase heat transfer medium for cooling. An independent, different temperature level can then be set in the condenser unit for further effective separation of the individual phase components.
- the condenser unit can be designed so that it can be operated for cooling at a lower temperature of the single-phase heat transfer medium than the heat exchanger device.
- pressure and temperature conditions are selected that are not below the dew point of the water portion in order to be able to keep the water vapor in the residual gas phase and to be able to discharge it.
- the condenser unit can be used optimally in this pressure-temperature range.
