Description

Data center module without oily centrifugal cooling system
Technical field
The present invention relates to a kind of data center module without oily centrifugal cooling system, it is a kind of cooling system for data center module.
Background technology
Progress along with science and technology, various computer application is also increasingly extensive, and such as servomechanism or data switching exchane, but computer is when running, computer can produce a work high temperature, and this work high temperature can make computer overheating, damages and produce, for fear of computer overheating, so can be with computer installation in a data center module, the cooling system of data center module is to reduce this work high temperature, so that the computer normal operation, so this cooling system has suitable importance.
Please cooperate with reference to shown in Figure 1, a kind of cooling system of data center module, it has a cooling tower 10, a cooler 11(Chiller) and the interior air heat exchanger 12 of a machine room.
Cooling tower 10 is to couple cooler 11 with pipeline, and cooler 11 is to couple air heat exchanger 12 in the machine room with pipeline.
As shown in Figure 1, an air 13 from data center module flows into air heat exchanger 12 in the machine room, and after heat exchange, and make it form a cooling-air 14, to offer data center module.
Absorb this from the cooling water of air heat exchanger 12 in the machine room of the heat of the air 13 of data center module, then flow in the cooler 11, and after heat exchange, again flow back to air heat exchanger 12 in the machine room, to carry out heat exchange with air 13 from data center module.
The heat of the cooling water of air heat exchanger 12 in then in cooler 11, absorbing from machine room from the water of cooling tower 10, and getting back in the cooling tower 10, and after carrying out heat exchange with an extraneous air 15, flow back to again in the cooler 11.
The above, it is the cooling water circulation for a typical data center module, but has various electronic equipments in the factor data machine room, but the problem of pipeline leakage might occur cooling water circulation, if in the data center module generation pipeline leakage is arranged, it certainly will cause suitable danger and loss.
Because the problem of above-mentioned pipeline leakage, the data center module of part is the design of using the secondary working fluid, this secondary working fluid is non conducting fluid, if produce the problem that pipeline leakage is arranged, it can not cause the problem of short circuit, but cooling system need to be filled the secondary working fluid constantly, and increase the secondary working fluid pump with once/quantity of secondary heat exchanger.
For reducing the power consumption of cooling system, adopt more efficient cooling system just to become an important problem, if adopt for example refrigerant direct circulation system, can save the water pump electricity consumption, but once/temperature difference that second heat exchanges easily causes the decrease in efficiency of cooling system, and the increase of cost.
Comprehensively above-mentioned, existing cooling system has following shortcoming:
One, pipeline leakage produces electronic equipment and threatens.
Two, the water pump of cooling water circulation needs power consumption.
Three, the cooling water of cooling water circulation easily and produce the temperature ladder between the air heat exchanger, and so that the decrease in efficiency of cooling system.
If four use the refrigerant cooling system of lubricating oil, lubricating oil may enter air heat exchanger, and can't leave air heat exchanger, and then causes the mistake oil of compressor to damage.
If the refrigerant cooling system of five non lubricant oils, it is to cross thermal control with the refrigerant that each other coolant expansion apparatus of evaporimeter carries out evaporator outlet, and so this system complexity is quite high, in case control unsuccessfully, forms easily the situation of hydraulic compression.
Six, the refrigerant cooling system of lubricating oil or the refrigerant cooling system of non lubricant oil are arranged, all adopt now the hot biography formula of radiating fin and level evaporimeter, hot transfer efficiency is poor, and refrigerant is large through the pressure loss of heat exchanger.
Summary of the invention
The object of the invention is to, provide a kind of data center module without oily centrifugal cooling system, the mistake oil that can solve existing pipeline leakage, power consumption, decrease in efficiency and compressor is damaged and is simplified the refrigerant control of supplying with a plurality of evaporimeters and can solve the problem that existing hot transfer efficiency is poor and the pressure loss is large.
In an embodiment, the invention provides a kind of data center module without oily centrifugal cooling system, it has a liquid-gas separator; At least one condenser, it couples this liquid-gas separator; One refrigerant expansion valve, it is located between this condenser and this liquid-gas separator; One driving governor, it is electrically connected this refrigerant expansion valve; One LS, its be located at one can sensing liquid refrigerants liquid level the position, this LS is electrically connected this driving governor; One without oily centrifugal compressor, and it couples respectively this condenser and this liquid-gas separator; And at least one evaporimeter, it uprightly is located in this data center module, and this evaporimeter couples this liquid-gas separator.
