5), oil cooling rack 9, be for placing mineral oil and soaking the device of equipment such as server.
The course of work that realizes oil cooling system of the utility model data center equipment needed thereby is as follows:
1), use characteristics such as mineral oil insulation, heat conduction, unsuitable oxidation, non-corrosiveness, fire prevention, nontoxic, good fluidity, the server of removing all heat dissipation equipments is immersed in oil cooling rack 9 units of filling mineral oil.When server was worked, server and other equipment can generate heat, and by heat transfer effect, heat is delivered in the mineral oil, and mineral oil is circulative convection in oil cooling rack 9, made heat to be diffused into uniformly, rapidly in the mineral oil of this oil cooling rack 9;
2), behind the pump start in the oil pump group, impeller high speed rotary motion in the oil pump, mineral oil after being heated is under action of centrifugal force, by oil pipe from oil cooling rack 9 in the inflow heat exchanger 5, after deep fat carries out heat exchange, return oil cooling rack 9 through the effect of oil pump again, carry out oil and circulate;
3), after mineral oil enters heat exchanger 5, pipe in the heat exchanger 5 has enlarged heat-conducting area, by heat-conduction principle, effectively the heat in the mineral oil is delivered in the cooling water, the mineral oil after the heat radiation is got back to by oil pipe and is continued to absorb heat in oil cooling rack 9 units;
4), behind the starting mode of pump in the water pump group, impeller high speed rotary motion in the water pump, the cooling water after being heated is got back to cooling tower 1 by water pipe and is cooled off under the water pump action of centrifugal force, to be transported to after the water cooling in the heat exchanger 5 again, so carry out circulating of water;
5), cooling tower 1 is the air of drying, enters in the tower through the twitch of blower fan 13, air and water carry out evaporation in cooling tower, thus with water cooling;
6), oily temperature control is between 40-50 degree centigrade, under this environment, server and equipment thereof can operate as normal, oil pump group and water pump group generally are made up of the oil pump more than 2 and water pump, under the normal condition, oil pump in oil pump group and the water pump group and water pump all are alternations, have only an oil pump and pump working at one time, and other oil pump and water pump are in stand-by state.Can monitor and control the work of oil pump and water pump by transducer and control circuit.When water pump and oil pump break down, transducer can receive signal, and signal is passed to control circuit, thereby can mask the fault pump, the pump of enabling other carries out periodic duty, and fault message is submitted to control centre, and therefore improved the serious forgiveness of oil cooling system, make that data center can stablize, continuous operation reliably;
As shown in Figure 2, realize that this required cover oil cooling heat dissipation equipment of the utility model is equipped with a cover robot control system(RCS) equipment, the working condition of each equipment is detected, and information collected feed back to supervision and management center.Robot control system(RCS) equipment can monitor and handle automatically fault, when the checkout gear of each equipment detects when unusual, can feed back to robot control system(RCS) equipment by electronic signal, robot control system(RCS) equipment will be handled unusually automatically, and information passed to supervision and management center, if the robot control system(RCS) device processes not, then can give the alarm and give supervision and management center with feedback information, remind the staff to carry out manual handle.Because robot control system(RCS) equipment is connected with supervision and management center, can collect Long-distance Control with each equipment to the every data in the oil cooling system by supervision and management center.
The robot control system(RCS) equipment of realizing oil cooling system of the utility model data center equipment needed thereby has functions such as monitoring fault, automatic handling failure, feedback information.The handling process of its various piece is as follows:
1), oil cooling rack 9 units, temperature sensor on oil cooling rack 9 units can be used for detecting the temperature of mineral oil in turnover oil pipe and the rack, if when temperature surpasses set point, information can be passed to the robot control system(RCS) device processes, and feed back to supervision and management center.There is a level balance valve oil cooling rack 9 sides, by oil pipe the oil cooling rack 9 in the stack of cabinets are coupled together, and under atmospheric effect, can regulate the liquid level of rack mineral oil in fluid automatically, make it to keep balance;
2), oil pump, water pump group part because oil, water pump group is made up of a plurality of oil pumps and a plurality of water pump, oil pump and water pump all are alternate cycles (each pump housing is rotated after starting 10-20 days) of using separately.When the pump housing in the work broke down, flow detector can pass to this information robot control system(RCS) equipment, and robot control system(RCS) equipment is closed the fault pump by sending electronic signal, and started stand-by pump, skipped over this pump in follow-up rotating.At last result is sent to supervision and management center, remind staff's maintenance or replacing, can again the fault pump be added circulation by turns after the staff disposes;
3), heat exchanger 5, when occurring unusually, temperature sensor can pass to information robot control system(RCS) equipment and handle, and feeds back to supervision and management center;
4), cooling tower 1, when occurring unusually, proximity transducer or temperature sensor can pass to information robot control system(RCS) equipment and handle, and feed back to supervision and management center.
5), the load of system design is with reference to the most cruel environment, so under general environment (when temperature is low), the speed that heat-sinking capability can produce greater than heat, this time, frequency converter can be started working, and system is saved energy and reduce the cost.
Realize oil cooling system of the utility model data center equipment needed thereby, behind the work certain hour, will carry out care and maintenance, thus normal, the stable work of assurance equipment, and its main contents have:
1), the cleaning of filter plant in mineral oil filtration and the system;
2), the cleaning of heat exchanger 5.Because heat exchanger 5 long-time running, the purity difference of the water that is used for cooling off, and the difference of the character of processing medium own causes heat exchanger 5 foulings, the inner passage sectional area is diminished even stop up, cause heat exchanger 5 heat exchange efficiencies to reduce, thereby influence the normal operation of oil cooling system and the safety of equipment, so heat exchanger 5 should regularly clean, remove dirt, to guarantee the high efficient heat exchanging of heat exchanger 5;
3), the maintenance of water pump group, oil pump group, check water pump group, oil pump group power lead, whether have aging, broken skin, power line copper core leaks outside, and checks whether water pump vane has earth, and foreign matter etc. is blocked out water impeller or delivery port, whether sound is good when checking pump operation, if assorted crisp sound is arranged, illustrate that water pump bearing damages, and needs maintenance, refuel, change.Whether leak electricity when checking pump operation, if electric leakage please be sent maintenance department's maintenance;
4), the maintenance of cooling tower 1.It is damaged loosening to check that cooling tower 1 water main, distributive pipe, shower nozzle have or not, in time repair, fix, thoroughly remove the dirt of water distributor and shower nozzle inside, to guarantee that water pipe is unimpeded, the shower nozzle water distribution is even, cleaning down cooling tower water pond and water outlet filtering screen avoid the incrustation scale dirt to accumulate blocking pipe.
The above only is preferred implementation of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical field, all in like manner be included in the scope of patent protection of the present utility model.
