Description
Technical field
The utility model relates to server cabinet cooling system, particularly relates to the server cabinet cooling system that between a kind of row, air-conditioning and liquid cooling apparatus combine.
Background technology
Along with the develop rapidly of information industry, people's computation machine equipment gets more and more, and requires also more and more higher to the operational speed of a computer.Therefore increasing large-scale calculations machine room is built and is come into operation, number of applications and the arithmetic speed of server increase considerably, its power consumption and heat dissipation capacity also in continuous increase, the demand of machine room heat dissipation equipment is increased thereupon.Using the machine room of traditional approach cooling, huge owing to running power consumption, namely the operating cost of 1 ~ 3 year reaches equipment purchasing cost.Therefore, the energy saving of heat dissipation system for computer room is more and more subject to the extensive concern of manufacturer and user.
Tradition cooling method reduces machine room air themperature, and then make Cryogenic air enter server, with thermal component forced-convection heat transfer, and heat when takeaway service device runs.Due to air ratio thermal capacitance and forced-convection heat transfer coefficients comparison low, air themperature can only be dropped to enough low guarantee heat radiation, according to the recommendation of GB, machine room air temperature should remain on about 24 DEG C.So, air conditioner in machine room needs the low-temperature receiver manufacturing very low temperature to cool air, and general machine room adopts compressor refrigeration system whole year operation, produces cryogenic freezing liquid or the low-temperature refrigerant of about 7 ~ 10 DEG C; In addition, air-conditioning also needs configuration Fan Regulation machine room air current composition, and configuration heating, damping device keep the constant temperature and humidity of machine room.According to statistics, under this mode, air conditioning energy consumption accounts for 35% ~ 45% of machine room total energy consumption, and wherein 60% ~ 70% electricity is consumed by compressor.Also outdoor cold source comprises outdoor new wind, cold liquid system cools naturally to have part air-conditioner set make use of, this way is mainly through reducing the running time of compressor, reach energy-conservation object, the power consumption of miscellaneous part can't reduce, and during summer high temperature, still need compressor cooling, power consumption when adopting air-conditioning naturally to cool is still larger; In addition, adopt the cooling of air conditioning mode, air-conditioning equipment more complicated, needs various mechanical device and rotating machinery, and initial cost is large, safeguards cumbersome.
During actual motion, the main heat sink parts in server are central processor CPU, and its heat dissipation capacity accounts for 80% of the total heat dissipation capacity of server, from a structural point, for the design of specific aim heat radiation provides the foundation condition.Temperature when CPU runs, generally between 60 ~ 80 DEG C, if adopt the mode that liquid directly cools, only needs the fluid temperature of 35 ~ 50 DEG C, just can meet CPU radiating requirements.This temperature is all annual all higher than the wet-bulb temperature of natural environment in overwhelming majority area.Therefore can pass through natural heat-conducting, produce the liquid of 35 ~ 50 DEG C the whole year, realize CPU natural heat dissipation.The heat radiation of miscellaneous part in server, is realized by the air conditioning of air-conditioning between row.By the processing mode of air-conditioning between liquid cooling+row, the safe and reliable operation of calculator room equipment can be ensured, nature refrigeration can be made full use of again, greatly reduce machine room heat radiation power consumption, save machine room operating cost, in addition, liquid cooling system only needs to play conveying fluid matasomatism, without the need to plant equipment such as refrigeration, heating, humidification, air-supplies, unit failure rate is low, safeguards simple.
Along with the high speed development of information industry, the arithmetic speed of CPU is constantly doubled, the heat of CPU also continues to increase, in the near future, only that air cooled mode will be difficult to meet the radiating requirements of server, only have liquid conductive mode could discharge enough heats, in view of this, the purpose of this utility model is to provide a kind of novel reliably energy-efficient server room cooling system.
Application number be 201010141693.8 Chinese patent " noise-free energy-saving server " a kind of noise-free energy-saving server is provided, comprise: 1) adopt heat pipe to substitute traditional fan forced convection mode in conjunction with liquid cooling mode and solve processor heat dissipation problem, eliminate fan noise; 2) DDR3 internal memory low in energy consumption is used to reduce noise; 3) hard disk uses solid state hard disc, eliminates hard disk noise; 4) fan-free efficient power is used to be system power supply; Concrete steps are as follows: adopt heat pipe to dispel the heat in conjunction with liquid cooling mode, heat pipe one end is connected with processor, the other end is connected with liquid pipe in heat exchanger, according to heat pipe height heat transfer system performance, the heat that processor produces is passed to the liquid pipe in heat exchanger, cold liquid flows in liquid pipe, heat pipe and liquid Guan Zhongleng liquid carry out heat exchange, cold liquid is heated, hydrothermal solution is discharged from heat exchanger, hydrothermal solution inputs cold liquid pool after chiller refrigeration, so circulates again, solve the heat dissipation problem of processor with this, liquid flow through liquid pump to support.This patent is based on heat pipe heat radiation, and main heat is absorbed by heat pipe, and then carries out heat exchange with the mode of liquid cooling and heat pipe, can only the partial heat of takeaway service device, and remaining waste heat there is no any measure to process.In addition, this patent still needs the refrigerating plant of refrigerant system to realize the cooling of hydrothermal solution, cannot realize naturally cooling completely, and energy saving and economy are all difficult to the lifting realizing matter.
The Chinese patent " a kind of container type data system " of application number 201220109057.1 relates to a kind of container type data system, comprise casing, be provided with for completing the rack that data calculate and the refrigerating system comprising at least one in the ranks air-conditioning in casing, rack is arranged in a row, and in the ranks air-conditioning is arranged between rack; The cold air channel being convenient to cold air circulation and the hot-air channel being convenient to the hot-air circulation produced when rack works is respectively arranged with at the Qianmen of rack and back door; In the ranks air-conditioning front end is towards cold air channel, and in the ranks air-conditioning rear end is towards hot-air channel.In the ranks air-conditioning and rack be side by side for this patent, cold wind from cold air channel air-supply after by hot-air channel return air, this is the design feature of air-conditioning in the ranks, and this patent only provides the refrigerating system of the rack arranged with row, how to arrange refrigerating system when not providing the many rows of rack to arrange.
