Description
(1) technical field
The present invention relates to a kind of high-density rack server radiating system.Belong to field of computer technology.
(2) background technology
Research shows, thermal failure is one of the main failure forms that comprises the electronic equipment of computing machine.Along with the increase of temperature, the crash rate of electronic equipment is exponential increase trend, even the device that has raises 10 ℃ in environment temperature, and crash rate increases and is twice above (being referred to as 10 ℃ of rules).The chip operation increase in temperature can be brought the electron transfer in the semiconductor, thereby causes chip failure even burn.
Because the thermal environment stress that heat produces is a kind of important working stress, statistics shows that 70% electronic equipment lost efficacy relevant with too high thermal environment stress.Therefore as far as electronic equipment,, also will make the crash rate of equipment reduce a considerable value even reduce by 1 ℃.
Frame (RACK) server is the server of a kind of outward appearance according to the unified standard design, cooperates the unified use of rack.The width of rack server is 19 inches, and height is unit (1U=1.75 inch=44.5 millimeter) with U, can divide into specifications such as 1U, 2U, 3U, 4U, 5U.How efficiently to utilize the computer cabinet inner space, be the problem of academia and industrial community exploratory development always.
The design aim of rack server mainly is in order to reduce taking of server space as far as possible, particularly in the NOWs of space sensitive with need under the situation of trust server.The design of dwindling on the space to cooling system has brought limitation.
Because inside dimension is fixed, the space is narrow and small, density of components is big; Therefore the heat dissipation problem of numerous heat generating components such as the building block of 1U RACK server such as central processing unit, internal memory, Chipset, external bus controller becomes a key issue such as this type of 1U RACK server server design.
Loongson3A (a kind of homemade processor brand) is the bigger a polycaryon processor of relative single core processor power consumption.Machine box for server is intensive being positioned in the standard cabinet often, and cabinet environment ventilation effect is relatively poor.Simultaneously, the processor quantity of server system is generally many, and power consumption is bigger, and the cabinet inside space is less, makes heat flow density (unit area internal heat generation performance number) bigger, and the heat dissipation that can take also receives space constraint.These bring challenges all for the heat dissipation design of server system.
Traditional a kind of solution is to increase number of fans, rotating speed merely.Its shortcoming is: the first, and the 1U lateral length is fixed, and installable industrial products standard specification number of fans is limited; The second, more fan, bigger rotating speed cause the noise of server bigger.
Traditional a kind of solution is to dispel the heat through adding the heating radiator that has fan for the big chip of thermal value.Its shortcoming is: at cabinet hour; The vertical blast that fan on the heating radiator produces can have a negative impact to the transverse convection inside and outside the cabinet; When convection current inside and outside the cabinet is not enough; The accumulation of heat that heating radiator produces raises the temperature in the cabinet in cabinet, and the high temperature in the cabinet influences the radiating effect of heating radiator conversely again.
Traditional a kind of solution is to increase the wind scooper of artificial design to form a plurality of air channels.Its shortcoming is: itself occupies certain space wind scooper, and the cycle of custom design is longer.
Therefore; How to take all factors into consideration type servers such as 1U RACK space constraint, reduce factors such as noise, cross-ventilation effect; In certain designed in the cycle, a kind of practicality is provided, the solution of dispelling the heat has become problem demanding prompt solution in the server design efficiently.
(3) summary of the invention
1. purpose:
The purpose of this invention is to provide a kind of high-density rack server radiating system, and be example, provide its concrete device and be provided with 1U ten six road rack servers.This cooling system is based on space constraint; Overcome the defective of traditional heat-dissipating system; Can make main radiating element temperature such as CPU lower and balanced more each other, avoid the various system failures that cause by system radiating, and prolong the mean time between failures and the serviceable life of total system.
2. technical scheme:
A kind of high-density rack server radiating system of the present invention designs as follows.This cooling system is made up of aerofoil fan group, heating radiator, cabinet casing, and aerofoil fan group and heating radiator all are installed in the cabinet casing.
Said aerofoil fan group is made up of the N+M desk fan, and wherein the N desk fan is positioned at cabinet casing front end, exhausting in the cabinet casing, and the M desk fan is positioned at the cabinet box back, air draft outside the cabinet casing.The odd test air discharging and radiating is blown in the two groups of fans collocation in front and back.Wherein, N, M are at least 2 respectively.Fans can partly or entirely select for use the fan with double pressure air draft performance to form where necessary.
Said heating radiator is a parallel fins formula shape, aluminium section bar matter, settle direction along fan shaft to.4～16 of the quantity of cpu chip (like Loongson3A) heating radiator; The quantity of Chipset (like MCP68) and communication chip (like IB) heating radiator can be 2～6 respectively.Heating radiator is covered in the said chip surface, and chip heat is absorbed and is dispersed in the surrounding air.On all cpu chip heating radiators fan is not installed, fan is not installed on all Chipset and the communication chip heating radiator yet.
The boxlike casing that said cabinet casing is the galvanized steel plain sheet material, it is made up of front and back panels, upper and lower panel and left and right side panel, adopts the L shaped fixed form of picking up the ears.Wherein the front and back panels of cabinet casing, left and right side panel all have through the suitable air vent of emulation experiment proof quantity.
The length and width of upper and lower panel, gauge are respectively L1mm*W1mm*T1mm (1000＞=L1＞=900, W1=440,1.3＞=T1＞=1.1), for example 950mm*440mm*1.2mm; The length and width of front and back panels, gauge are respectively L2mm*W2mm*T2mm (L2=440, W2=44.5,1.3＞=T2＞=1.1), for example 440mm*44.5mm*1.2mm; The percentage of open area of cabinet casing front panel 19 is 40%～80%, for example 60%; Perforate is positioned at the front portion of front end fan 7; The length and width of left and right side plate, gauge are respectively L3mm*W3mm*T3mm (L3=L1, W3=44.5,1.3＞=T3＞=1.1), for example 950mm*44.5mm*1.2mm.
In order to leave air vent in the position that is positioned at front and back panel on the wind path, the power switch of cabinet casing front end adopts the card extender design that is independent of mainboard, places the preceding left end of cabinet casing, comprises 4 groups of SRs, 4 groups of power knobs, 4 groups of LED lights; Medial axis is avoided in the exit position of cabinet cabinet rear panel, and the rear panel interface comprises 4 USB, 4 RJ45,2 IB chip interfaces.
The cabinet casing adopts the L shaped mode of picking up the ears to fix, and does not use guide rail, and its objective is increases cabinet box house space, to increase the mainboard width, reduces heat flow density.
In order to make wind path unobstructed, cpu chip is arranged in mainboard central authorities in two separate ranks.The same column cpu chip vertically is positioned on the straight line.Internal memory branch multiple row places the mainboard both sides, and same column vertically linearly.Chipset (like MCP68) and communication chip (like IB) are on the gap path between cpu chip and the memory bar.Cabinet casing upper and lower panel, in save as the wind-guiding pipeline that the cpu chip heating radiator has formed a relative closure; The high blast that the aerofoil fan group produces can better be kept in the wind-guiding pipeline; The heat of heater members such as processor is discharged the cabinet casing, overcome length effect to a certain extent.
Processor is the more serious parts that generate heat, and it can be operated under the higher temperature simultaneously, and a lot of miscellaneous part belongs to temperature sensitive parts, and like clock circuit, temperature variation causes frequency drift easily.If there is not the air channel of isolation relatively; Whole cabinet casing is in a warm area; The heat that processor produces can cause that temperature is whole in the cabinet casing raises, though processor can be under this temperature operate as normal, some other equipment such as clock also may not operate as normal.The air channel has produced two different warm areas after separating, and has reduced the influence of high heat resource equipments such as processor to other equipment.
Processor is as one of high heat resource equipment, and its heat radiation is the emphasis of considering in this cooling system design.Because the restriction of the crosswise fixed in 1U rack server space laterally can only be put 2 processors at most side by side.When putting, the temperature that is placed on the inlet air of accepting near the processor of air inlet fan one end is lower, blast is bigger, and the processor of back, because the temperature of the inlet air of accepting is higher, blast is less, radiating effect receives obvious influence.This is the altitude temperature difference effect that the length factor in air channel causes.The result of this altitude temperature difference effect is exactly that different processor parts are because the difference of present position has different crash rates and life cycle.The present invention uses two methods to weaken this influence:
(1) except the perforate of cabinet casing front and back panel, also increases the left and right side perforate of cabinet casing.For the parts such as processor away from air inlet fan one end, but the outside cold wind slave box body side with ambient temperature blows to these parts.Should consider fan type selecting, longitudinal air flow and factors such as crossflow, interface exit position by the simulation means compromise, confirm percentage of open area, the position of opening of front and back panel and left side plate perforate.Left side plate is being of a size of perforate on the zone of 120*30mm respectively; Percentage of open area is 50%～70%; Near being centered close to some main source of heat release of mainboard and being positioned at 2/3～3/4 place of whole wind path length of opening area is for example near the motherboard power supply module and be in the zone of transition of 1-12 cpu chip and 13-16 cpu chip.
(2) parts such as processor away from air inlet fan one end use larger-size heating radiator, compensate the negative effect that altitude temperature difference effect brings through bigger area of dissipation, thereby make the radiating effect basically identical of parts such as the processor acquisition that is in diverse location.To the chip of same kind, be designed to X1mm*Y1mm*Z1mm (the wide * of long * is high) near the heating radiator physical dimension of air inlet, be designed to X2mm*Y2mm*Z2mm (the wide * height of long *) away from the heating radiator physical dimension of air inlet.1.33X1＞=X2＞=1.25X1 wherein, Y2=X2,1.33Z1＞=Z2＞=1.25Z1
In order to shorten cabinet length as far as possible, reduce length effect among the present invention, the mainboard profile is designed to be " recessed " font, fan is placed at mainboard depression position, and external interfaces such as USB are placed at outstanding position.
In order to reduce cabinet casing inside conductor practicing thrift cabinet box house space, and make wind path unimpeded among the present invention, two identical mainboards in the cabinet casing adopt the mother daughter board connector modes interconnected.
Adopt CF (Compact Flash) card to replace hard disk among the present invention, practiced thrift cabinet box house space, and helped wind path unimpeded.
Cooling system of the present invention can be used for ten six road servers of 1U.The 1U server is as the strongest a kind of standard rack server of space constraint, and its cooling system can be used for 2U and the above server of 2U.To more than 1U and be less than ten six tunnel server, way of realization of the present invention is consistent, realizes that effect is superior at present 1U ten six road servers of practical implementation theoretically.
3. advantage and effect:
A kind of high-density rack server radiating system of the present invention; With the prior art ratio; Its advantage is: (with 1U ten six road rack servers is example to have successfully managed the heat density problem of high density server; In the space of 1U, held the AC-DC power supply of 16 cpu chips, 32 DDR2 memory bars, 4 IB chips, 4 MCP68 chips and 1 1200W); The radiating equipment that adopts need not special; Do not need complicated heat dissipation technologys such as water-cooled, hot pipe technique; The mainboard symmetric design requirement of cooling system design compliance with system greatly reduces overall system design complexity and fabrication cycle and cost, has good promotion prospect.
