As an example, the assignment of traffic in liquid cooling system by computer fluid dynamics (English:
The mode of Computational Fluid Dynamics, referred to as: CFD) emulation determines the flow point of newly-designed liquid cooling system
With scheme.Currently, often relying on the theoretical base of technical staff during carrying out CFD emulation when designing some liquid cooling system

The equipment such as machine, tablet computer.
It is understood that above-mentioned scene is only a Sample Scenario provided in an embodiment of the present invention, the embodiment of the present invention
It is not limited to this scene.
With reference to the accompanying drawing, it is adjusted by embodiment come the flow of liquid cooling system a kind of in the present invention will be described in detail embodiment
The specific implementation of method.
Referring to fig. 2, a kind of flow diagram of the flow method of adjustment of liquid cooling system in the embodiment of the present invention is shown.It should
Method can specifically include:
Step 201, the initial interface parameter for obtaining liquid cooling system, as current interface parameter.
It is connection between liquid cooling plate it is understood that including muti-piece liquid cooling plate in liquid cooling system.Interface, which refers to, to be used for
The channel of adjacent liquid cooling plate is connected, circle can be presented in the interface of liquid cooling system.Interface parameters can refer to be connect for characterizing this
The parameter of mouth size, can specifically refer to the internal diameter of circle interface.
When there is the design requirement of liquid cooling system, since interface parameters (such as interface internal diameter) difference will affect each liquid cooling plate
Flow, so, interface parameters that can be suitable for different interface settings, to control the assignment of traffic of the liquid cooling system.
It, can be according to the experience or theory of technical staff when facing the design requirement of liquid cooling system when specific implementation
Knowledge designs an initial liquid cooling system；Then, by carrying out GTD model and fluid domain extraction etc. to the initial liquid cooling system
Processing, obtains initial interface parameter, is denoted as current interface parameter.
Wherein, initial liquid cooling system is that obtained liquid cooling system after initial designs is carried out according to design requirement, specifically can be with
It is the liquid cooling system that technical staff draws in design drawing or design software.Initial interface parameter, including but not limited to: just
The internal diameter of each interface in beginning liquid cooling system.
As an example, technical staff can input the initial liquid cooling mould of design according to design requirement in CAD model
Type, and initial liquid cooling is obtained to processing operations such as GTD model and the fluid domain extractions of the initial liquid cooling model by CAD model
The initial interface parameter of each liquid cooling plate in system；Then, by way of the project is called batch processing in CAD model,
The initial interface parameter for getting the liquid cooling system, as current interface parameter.
It, specifically can be with it should be noted that may include the liquid cooling system radiating requirements in the design requirement of liquid cooling system
It is presented as the object reference flow of each liquid cooling plate in the new liquid cooling system of design, that is, needs each liquid cooling when reaching radiating requirements
The target flow of plate distribution.
As an example, the object reference flow can be the flow-rate ratio of each liquid cooling plate demand in the liquid cooling system
Example.Such as: for the liquid cooling system including three liquid cooling plates, the heat dissipation effect reached according to required by design requirement needs this
The ratio between flow obtained after the distribution of three liquid cooling plates is 1:2:3.
As another example, the object reference flow can also be the stream of each liquid cooling plate demand in the liquid cooling system
Amount.Such as: for the liquid cooling system including three liquid cooling plates, it is assumed that the total flow of the liquid cooling system is 1.2m3/ h (cubic meter/
Hour), then, the heat dissipation effect reached according to required by design requirement needs the stream obtained after the distribution of these three liquid cooling plates
Amount is respectively as follows: 0.2m3/h、0.4m3/ h and 0.6m3/h。
Step 202, fluid mechanical emulation is carried out to the liquid cooling system according to the current interface parameter, obtains practical stream
Amount.
It is understood that fluid mechanical emulation, in particular to the ginseng inputted using fluid mechanics knowledge, simulation and analysis
The flowing of liquid, obtains the process of simulation result in the corresponding model of number.Fluid mechanical emulation specifically can emulate mould by CFD
Block is realized.
Wherein, simulation result can be the actual flow for the liquid cooling system that interface parameters is current interface parameter.The reality
When flow refers to that emulation coolant liquid is set as the liquid cooling system of current interface parameter by interface parameters, the stream of each interface generation
Amount.
It should be noted that not only need to call the design parameters such as the current interface parameter of liquid cooling model before emulation,
Also need to preset some current simulation parameters, such as: the material of pipeline, coarse journey in each liquid cooling plate in simulated environment
Degree, coefficient of friction etc..
In some possible implementations, in step 202 according to the current interface parameter to the liquid cooling system into
Row fluid mechanical emulation obtains actual flow and can specifically include referring to Fig. 3:
Step 301, the structural model of the liquid cooling system is set according to the current interface parameter and current simulation parameter.
Step 302, flow dynamics analysis and calculating are carried out to the structural model, obtains the practical stream of the structural model
Amount.
When specific implementation, the fluid mechanical emulations such as CFD emulation module tool can call liquid in the design tools such as CAD module
Current interface parameter of cooling system etc., and it is pre-set current in the fluid mechanical emulations tool such as obtain the CFD emulation module
Simulation parameter；Then, according to the current interface parameter and current simulation parameter, the structural model of the liquid cooling system is set；It connects
, flow dynamics analysis and calculating are carried out to the structural model by the fluid mechanical emulations such as CFD emulation module tool, are somebody's turn to do
The actual flow of structural model.
As an example, in order to coolant liquid can fast and efficiently can be emulated during fluid mechanical emulation
The effect for flowing through liquid cooling system can also include: between step 301 and step 302
Step 303, grid dividing is carried out to the structural model, the structural model after being divided.
So, it is also possible to carry out flow dynamics analysis and calculating to the structural model after division in step 302, is tied
The actual flow of structure model.
It is understood that being imitated to improve the fluid mechanical emulations such as CFD emulation module tool to the emulation of liquid cooling system
Rate can generally carry out the processing such as simple GTD model and fluid domain extraction to the structural model of the liquid cooling system of setting, still,
The structural model that above-mentioned treatment process will lead to emulation excessively idealizes, and deviates actual structural model, that is, increase emulation and
Actual deviation causes the meaning of emulation to be had a greatly reduced quality.Based on this, the setting liquid cooling system of step 301 in the embodiment of the present invention
Current simulation parameter based on structural model can be the practical stream obtained according to preset experimental result and last emulation
The simulation parameter that the simulation parameter that difference between amount uses when emulating to the last time obtains after being modified.
Wherein it is possible to experimental stand corresponding with liquid cooling system is established, the calibration for current simulation parameter.Such as Fig. 4 institute
Show, is the schematic diagram of an experimental stand, including liquid cooling plate 401, pipeline 402, connector 403, flowmeter 404, pressure gauge
405, water pump 406 and expansion tank 407 etc..Specific calibration process may include: to be placed in the interface on experimental stand currently
At interface parameters, and by laboratory facilities test the experimental stand set experimental result, in particular to each interface
Empirical flow；Then, compare the experimental result and the last time emulates obtained actual flow, obtain difference between the two；
Then, the simulation parameter used when being emulated using the difference to the last time is modified, and revised simulation parameter is denoted as
Current simulation parameter；Finally, current simulation parameter is set in the fluid mechanical emulations tool such as CFD emulation module, to provide
Data basis has been accomplished fluently in the emulation for approaching reality as far as possible.
Step 203, judge whether object reference flow and the actual flow match, if matching, thens follow the steps
204, otherwise, execute step 205.
It is understood that actual flow and object reference flow matches, indicate the corresponding liquid cooling system of current interface parameter
System meets design requirement, can be used as the foundation for producing practical liquid cooling system；Actual flow and object reference flow are not
Matching indicates that the corresponding liquid cooling system of current interface parameter does not meet design requirement also, needs further to adjust the liquid cooling system
Interface parameters so that according to interface parameters adjusted be arranged liquid cooling system more approach design requirement.
As an example, judge whether the object reference flow and the actual flow match in step 203, have
Body, which can be, judges whether the difference between the object reference flow and the actual flow is less than preset flow threshold.
Wherein, preset flow threshold refers to pre-set for determining that object reference flow and actual flow match
Object reference flow and actual flow between the maximum different value that allows.When the actual flow and the object reference flow
Between difference be less than preset flow threshold, then it represents that object reference flow and actual flow mismatch；Otherwise, work as actual flow
Difference between the object reference flow is not less than the preset flow threshold, then it represents that object reference flow and practical stream
Amount mismatches.
Step 204, using the current interface parameter as target interface parameter.
When specific implementation, when actual flow and object reference flow match, the corresponding liquid of current interface parameter is indicated
Cooling system meets design requirement, can export using the current interface parameter as target interface parameter as design result, and
In this, as the foundation for producing practical liquid cooling system.
Step 205, the current interface parameter is adjusted using the object reference flow and the actual flow, according to tune
Interface parameters after whole updates the current interface parameter, returns and executes above-mentioned steps 202.
When specific implementation, when actual flow and object reference flow mismatch, the corresponding liquid of current interface parameter is indicated
Cooling system does not meet design requirement also, needs further to adjust the interface parameters of the liquid cooling system, so that being connect according to adjusted
The liquid cooling system of mouth parameter setting more approaches design requirement.
It is understood that in order to make current interface parameter adjusted applied to the actual flow after fluid mechanical emulation
Object reference flow can be approached, then, need with object reference flow and actual flow for according to current interface parameter into
Row adjustment.
In one example, the mode for adjusting current interface parameter can specifically include: calculate the target ginseng of input
Examine the difference between flow and actual flow；The current interface parameter is adjusted according to the difference, so that adjustment
Current interface parameter afterwards carries out the obtained actual flow of fluid mechanical emulation and approaches the object reference flow.
When specific implementation, above-mentioned current interface parameter can be adjusted by genetic algorithm, specifically: target is joined
It examines flow, actual flow and current interface parameter to be input in preset trained genetic algorithm, output adjustment strategy,
Such as: 20 percent is tuned up, obtains current interface parameter adjusted according to adjustable strategies, alternatively, directly after output adjustment
Current interface parameter.
It is understood that give current interface parameter feedback adjusted to design tool such as CAD module, it then, should
The data for including current interface parameter are imported into the fluid mechanical emulations tool such as CFD emulation module by design tool again, are held
