Description

The server radiating system that liquid cooling apparatus and auxiliary radiating device combine
Technical field
The utility model relates to server cabinet cooling system, particularly relates to the server radiating system of a kind of liquid cooling apparatus and auxiliary radiating device combination.
Background technology
Along with the continuous increase of IDC computer room of internet data center high density rack, the integrated level of equipment is more and more higher, and disposal ability also increases gradually, but the power consumption of equipment also increases thereupon, causes the caloric value of equipment within machine cabinet more.According to statistics, in current domestic large-scale IDC machine room, equipment cabinet server caloric value is large, and is that annual 8760h runs substantially, for not adopting the machine room of new wind, the whole year all needs cooling, causes air conditioning energy consumption huge, and its air conditioning energy consumption accounts for 40% ~ 50% of the overall energy consumption of data center module.
Traditional data machine room air supply mode has the modes such as the air-supply of base plate air channel, the air-supply of cold and hot channel separation and the refrigeration air-supply of full room, this pattern has not met the refrigeration demand of modernization machine room high density rack, has occurred the problems such as local overheating, power consumption are large, air conditioner in machine room energy consumption is too high, noise is large.Simultaneously precise machine room air conditioner needs repeatedly humidification, dehumidifying running or supporting Special dehumidifier carry out machine room air humidity, dew point controls, and to guarantee that device interior condensation does not occur, causes that computer-room air conditioning system refrigerating efficiency reduces, energy consumption increases.If the heat dissipation problem of machine room solves bad, will the safe operation of serious threat calculator room equipment.Therefore, how when meeting equipment use requirement, the energy consumption effectively reducing air-conditioning system in machine room is the major issue that air conditioner industry and data center module operation industry face.
Consider from Energy Angle, have at present directly to adopt and outdoor air is introduced the indoor scheme for machine room cooling, its advantage is that refrigerating efficiency is high, initial cost is low, energy consumption is low, but shortcoming is after introducing outdoor cold air, make room air cleanliness factor, humidity be difficult to ensure, bring potential safety hazard, later stage operation maintenance amount is larger.Also have in addition and adopt gas gas honeycomb heat exchanger, by heat pipe hot-air and outdoor cold air indirect heat exchange, thus reduce temperature in machine room; Its advantage does not introduce outdoor air, and do not affect cleanliness factor and the humidity of the air in machine room, shortcoming is that initial cost is relatively high, and heat exchanger structure more complicated, easily blocks, and needs periodic cleaning, and maintenance workload is large.
And along with the development of server technology, the server application of high-power, high heat generation density is more and more, and be irreversible development trend, the maximum operate power of the single rack of current part industry user reaches about 10 ~ 15kW, but due to the limitation of cooling air mode radiating efficiency, make the application of high-power server also be difficult to break through more than 15kW/ rack.
Liquid-cooling heat radiation is the most efficient, the state-of-the-art heat sink conception that developed recently gets up, its principle is that liquid heat transferring medium is directly passed into the server internal with liquid cooling function, main heater element--the heat that chip (CPU) produces is taken away (accounting for 70 ~ 80% of whole server caloric value), adopt liquid-cooling heat radiation scheme, unit rack power even can be made in theory to break through more than 50kW/.But current this heat sink conception exists only in Scientific Research in University Laboratory and only a few enterprises is studied among a small circle, and fail formed applied generalization application, one of very important reason, because the server of this employing liquid-cooling heat radiation, its rack needs built-in liquid cooling water distribution system, this just needs to carry out special Custom Design to liquid cooling server cabinet, and rack manufacturer is generally standardized production, present stage does not grasp the key technology that liquid cooling water distribution system designs yet, the enclosure product of built-in liquid cooling water distribution system cannot be provided for liquid cooling server user is supporting, the particularly upgrading of old machine room, if want to change liquid-cooling heat radiation scheme into, the rack of built-in liquid cooling water distribution system all will be replaced with to whole server cabinet, that improvement project amount and cost are all very high, the development greatly having limited to liquid-cooling heat radiation technology is popularized.In addition, liquid cooling heat radiation system can only take away the server caloric value of 70 ~ 80%, but still have the caloric requirement auxiliary refrigeration device of 20 ~ 30% to bear, for the high-density applications of this Single Cabinet power of liquid cooling server up to more than 50kW, each rack needs the heat (20 ~ 30% of gross power) of auxiliary refrigeration device process 10 ~ more than 15kW, if auxiliary refrigeration device still adopts traditional wind-cooling heat dissipating mode, very easily there is the hot localised points problem of rack, affect the component life of server, this is also that the cold server of higher density fluid applies the problem that can not ignore.
The application number Chinese patent that to be 201010261284.1 patent names be " server cabinet and liquid cooling heat radiation system thereof " discloses a kind of server cabinet, comprise shell, be located at the server in described shell and liquid cooling heat radiation system, the heat-conducting plate near described server is provided with in described shell, described liquid cooling heat radiation system comprises is located at refrigerator outside described shell and by described heat-conducting plate and the hot linked pipeline of refrigerator, the heat produced during described server work forms hot-fluid in described shell, described hot-fluid cools at heat-conducting plate place, described pipeline extends outside described shell, and be connected with the opposite end of described refrigerator respectively, heat exchange is carried out so that described heat-conducting plate is passed to refrigerator from the heat that server absorbs.Although this patent is also adopt liquid-cooling heat radiation, the heat of server can not be taken away by liquid cooling heat radiation system completely, therefore has the problems such as hot localised points, life-span be short.
The application number Chinese patent that to be 201210545675.5 patent names be " a kind of server cabinet cooling system " discloses a kind of server cabinet cooling system, comprise the liquid cooling case being placed in server cabinet inside, water-filled radiator in server cabinet, air radiator in cabinet, first liquid reserve tank and outdoor external condensation system, liquid cooling case comprises the finned heat exchanger be integrated in a case, plate heat exchanger and the first water pump, plate heat exchanger hot water side, first water pump, in first liquid reserve tank and server cabinet, water-filled radiator connects into the first circulation circuit by pipeline, external condensation system, air radiator in cabinet, finned heat exchanger and plate heat exchanger cold water side connect into the second circulation circuit by pipeline.This patent adopts the second circulation circuit to take away the heat of the first circulation circuit, but the radiator of the first circulation circuit carries out heat conduction to whole server cabinet inner air, there is no and directly carry out heat conduction for server heater chip, this causes, and this patent radiating efficiency is low, weak effect, in addition, first circulation circuit is provided with the first water pump, generate heat during the first water pump operation more, need to arrange heat exchanger specially to transmit the heat that the first water pump operation gathers, this causes burden to system undoubtedly, thus reduces the radiating efficiency of system further.
