GPU high density spends computer room liquid cooling: GPU high density spends design of system of computer room liquid cooling and pipeline to optimize
Wait for flying development of the technology as artificial intelligence, big data, GPU computation demand increases increasingly. In numerous technology domain, GPU high density spends a computer room to become crucial infrastructure. To satisfy high-powered computation requirement, emerge as the times require of technology of computer room liquid cooling. The article will spend design of system of computer room liquid cooling and pipeline to optimize around GPU high density spread out development to discuss.
One, overview of system of liquid cooling of computer room of GPU high density
System of liquid cooling of computer room of GPU high density is the cooling means of a kind of efficient, environmental protection, take away the quantity of heat that GPU produces through circular cooling fluid, the constant temperature that realizes a computer room, low a confusion of voices moves. Compare traditional wind cold system, liquid cooling system has the following advantage:
1.Cooling efficiency is tall: The cooling efficiency outclass of liquid cooling system wind cold system, can satisfy GPU high density to spend the demand with hot to coming loose computer room.
2.Moving stability: Liquid cooling system suffers environmental temperature the influence is minor, can assure the stability of computer room temperature.
3.Reduce specific power consumption: Liquid cooling system is designed through optimizing pipeline, reduce specific power consumption, raise energy utilization rate.
4.Reduce noise: The noise when liquid cooling system moves is inferior, provide a quiet working environment for the computer room.
2, design of system of liquid cooling of computer room of GPU high density
1.Cooling fluid choice: Choosing appropriate cooling fluid is the key that liquid cooling system designs. Cooling fluid should have the good heat conduction performance, chemical stability, character such as biology consistence. Current, commonly used cooling fluid has glycol, third 2 alcohol.
2.Cooling fluid circulatory system: Mix according to computer room dimensions medicinal powder hot demand, design sound cooling fluid circulatory system. Circulatory system includes the facility such as cooling pump, cooling tower, conduit.
3.Pipeline design: Pipeline designs the core link that is design of liquid cooling system. Pipeline design should follow the following principle:
(1) pipeline distribution is equitable, shorten as far as possible distance of cooling fluid flow.
(2) pipeline diameter moderate, avoid meticulous or too thick.
(3) pipeline material has sex of good corrosion resistance, compression.
4.Cooling module designs: Cooling module is the main component of liquid cooling system, its design should satisfy the following requirement:
(1) cooling efficiency is tall, can take away the quantity of heat that GPU produces quickly.
(2) the structure is compact, facilitating installation and maintenance.
(3) have come loose goodly hot property.
3, pipeline is optimized
1.Pipeline layout optimizes: Put according to computer room layout and equipment, layout of sound program pipeline, reduce pipeline length and curve a frequency, improve efficiency of cooling fluid flow.
2.Conduit material optimizes: Choose right conduit stuff, wait like stainless steel, copper, raise the corrosion resistance of conduit and compression sex.
3.Pipeline link optimizes: Use solder, the reliable join means such as threaded coupling, surely truly connective sealing and stability.
4.Conduit accessory optimizes: Choose efficient and energy-saving conduit accessory, wait like valve, filter, raise a system to run efficiency and reliability.
4, summary
GPU high density spends design of system of computer room liquid cooling and pipeline to optimize is the key that stability of safeguard computer room runs. Pass layout of circulatory system of reasonable design cooling fluid, pipeline and conduit data, can improve cooling efficiency, reduce specific power consumption, reduce noise, provide a comfortable, efficient work environment for the user. In future, as ceaseless progress of the technology, liquid cooling system will spend computer room domain to produce mainer and mainer effect in GPU high density.
