Description
Technical field
This utility model relates to data center machine room cooling system technical field, particularly relates to a kind of for backwater double loop cooling recirculation system.
Background technology
Along with being continuously increased of IDC computer room of internet data center high density rack, the integrated level of equipment is more and more higher, disposal ability also strengthens gradually, the caloric value making equipment within machine cabinet is also increasing, traditional air-cooled data center module, room air is cooled down by compressing kind of refrigeration cycle by it by precision air conditioner again, send in machine room by raised flooring, this pattern has been unsatisfactory for the refrigeration demand of modern machine room high density rack, occurs in that the problems such as hot-spot, power consumption are big, air conditioner in machine room energy consumption is too high, noise is big.Especially Large-Scale Interconnected network data center, its pyrotoxin is the server being placed in rack, and air enters rack via rack front portion, and the blower fan that high temperature air is carried by server after server heats is blown out by rack back door, enters machine room spatial environments.If the heat dissipation problem of machine room solves bad, will the safe operation of very serious threat calculator room equipment.
For the shortcoming of tradition air cooling system, the advantage of liquid cooling recirculation system is more prominent.Existing liquid cooling recirculation system supply channel adopts one-way fluid path, and pipeline adopts coating steel pipe, adopts solder technology to connect between described pipeline pipe fitting, and inner-outer circulation refrigerating medium all adopts municipal administration water.After such liquid cooling recirculation system ran for 1 year continuously, it may occur that serious inner loop pipeline blocking.Finding the serious corrosion of pipeline and fouling, blocking heat pipe water-cooled module and water distribution flexible pipe in engineering unloading process, demolition and maintenance are quite inconvenient, and system stability is poor, and reliability is not high.
Application number be 201010033887.6 Chinese patent " a kind of cooling machine cabinet method and device " provide a kind of cabinet heat dissipation device, including: rack, top is provided with hot-blast outlet, and bottom is provided with cold air inlet；Blowing unit, is carried by rack bottom from bottom to top by the cold wind inputted by cold air inlet；Liquid cooling unit, cools down the hot-air discharged by hot-blast outlet, and is input in rack by cold air inlet.Although vertically refrigeration and water-cooling pattern are organically combined by this patent, but energy consumption is big, maintenance inconvenience, it is impossible to be applied to the server radiating of large-scale machine room.
Utility model content
In view of this, the purpose of this utility model is in that to overcome the deficiencies in the prior art, it is provided that a kind of confession backwater double loop cooling recirculation system meeting modernization machine room high density rack refrigeration demand, the problem solving machine room hot-spot, maintenance difficult.
In order to solve above-mentioned technical problem, this utility model adopts following scheme to realize:
A kind of for backwater double loop cooling recirculation system, including including the internal circulation system of cooled unit and including the external circulating system of cooling unit, described internal circulation system and external circulating system connect the heat exchange realizing both by intermediate heat crosspoint, and described internal circulation system and external circulating system adopt loop design to make the refrigerating medium can two-way flow in pipeline.
Refrigerating medium in internal circulation system is transported to cooled unit and realizes accurate heat exchange, the shortcoming solving machine room hot-spot.Internal circulation system and external circulating system carry out heat exchange and make external circulating system take away the heat of internal circulation system, refrigerating medium flows respectively in internal circulation system and external circulating system, owing to internal circulation system and external circulating system there will be fault unavoidably after long-play, refrigeration system on conventional art, just can keep in repair after shutting down, and this utility model innovatively adopts loop design make the refrigerating medium can two-way flow in the loop, when needing repairing, by changing the flow direction of refrigerating medium, that is to say that refrigerating medium does not walk out of order pipeline, therefore problematic pipeline is keeped in repair by maintainer under non-stop-machine premise.Described cooled unit can be the rack in machine room or other parts, and described cooling unit is cooling tower or other heat-exchanger rig；Described intermediate heat crosspoint is plate type heat exchanger or other heat-exchanger rig.
Described internal circulation system also includes internal recycle for water loops and internal recycle backwater loop, cooled unit supplies water loops and internal recycle backwater loop to be connected with internal recycle respectively and realizes heat exchange, described internal recycle is provided with valve to control the trend of refrigerating medium for water loops and internal recycle backwater loop, described internal recycle is provided with at least one internal recycle water supply arm for water loops and is connected with intermediate heat crosspoint, described internal recycle backwater loop is provided with at least one internal recycle return branch and is connected with intermediate heat crosspoint, refrigerating medium is arranged into internal recycle water supply arm after entering intermediate heat crosspoint heat exchange from internal recycle return branch again.
So that refrigeration system is more for ease of maintenance process and run for a long time, it is provided with internal recycle for water loops and internal recycle backwater loop, refrigerating medium enters cooled unit from internal recycle for water loops and carries out heat exchange, then internal recycle backwater loop is exited into from cooled unit, the refrigerating medium of internal recycle backwater loop enters intermediate heat crosspoint by internal recycle return branch and carries out heat exchange, rear outflow intermediate heat crosspoint enters internal recycle for water loops by internal recycle water supply arm, so realizes the circulation of refrigerating medium.Loop is provided with corresponding valve; such as valve is set between junction point and junction point that rack connects for water loops with internal recycle; between junction point and junction point that internal recycle water supply arm connects for water loops with internal recycle, valve etc. is set; certain section of pipeline in the future after breaking down, can pass through to close the valve at this section of pipeline two ends, it is achieved refrigerating medium flows from other direction; supply water, backwater works on; do not need shutdown to keep in repair, greatly reduce maintenance difficulty, strengthen system stability.The concrete setting of valve, in order that the flow direction that when pipeline breaks down, can realize refrigerating medium by adjusting the keying of valve changes, is not construed as limiting by the setting of valve here.
The quantity of described intermediate heat crosspoint, internal recycle water supply arm and internal recycle return branch is consistent.
Being arranged to quantity consistent, this is a kind of preferred mode, it is therefore intended that more efficient heat exchange and prevent multiple failure problems.Reason is in that, an internal recycle water supply arm and an internal recycle return branch are connected with an intermediate heat crosspoint, then refrigerating medium enters back into internal recycle water supply arm after entering intermediate heat crosspoint from internal recycle return branch.If the quantity of three is inconsistent, such as the quantity of internal recycle water supply arm and internal recycle return branch is respectively two, intermediate heat crosspoint is one, then two adjust the entrance of the public intermediate heat crosspoint of internal recycle return branch, article two, the outlet of an internal recycle water supply arm also public intermediate heat crosspoint, so, the refrigerating medium flow of intermediate heat transfer unit is greatly increased, increase the weight of its load so that heat exchange efficiency reduces.Such design simultaneously can realize the using and the reserved, increases the redundant ability of system.
