Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than the embodiment of whole.It is based on
Embodiment in the present invention, it is all other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
To make the advantage of technical solution of the present invention clearer, the present invention is made specifically with reference to the accompanying drawings and examples
It is bright.
As shown in figure 1, electrical control cabinet provided in an embodiment of the present invention includes：Cabinet, is internally provided with two-way in cabinet
Cooling system, two-way cooling system includes：The pipeline 1 of conveying coolant；Radiator 2, its two ends are respectively connecting to the two of pipeline 1
End constitutes a closed circuit, and radiator 2 makes to carry out the heat that heat exchange absorbs coolant between coolant and extraneous air
Shed；First pump 3 and the second pump 4, are arranged at making coolant be flowed in pipeline in pipeline, and the first pump 3 and
The direction of the conveying coolant of two pump 4 is contrary, the first pump 3 and the alternation of the second pump 4；Control system is additionally provided with cabinet
System, it includes：Control unit 5, radiator 2, the first pump 3 and the second pump 4 are connected to control unit 5；Detector unit 6, its company
Control unit 5, the open/close states of the electric device inside the detection electrical control cabinet of detector unit 6 are connected to, and open/close states are passed
Deliver to control unit 5, control unit 5 controlled according to the open/close states of the electric device for receiving radiator 2, the first pump 3 or
The keying of the second pump of person 4, wherein, every a scheduled time, control unit 5 controls the first pump 3 and the second pump 4 and carries out alternately work
Make；Temperature sensor 7, it is arranged on the inside of cabinet and is connected with control unit 5, for monitoring temperature and handle inside cabinet
Temperature value sends control unit 5 to, if the temperature inside cabinet is more than one first predetermined temperature, needs to change the cooling in pipeline
Liquid.
Wherein, coolant can be with water, or and other liquid that can play cooling effect, do not do here concrete
Restriction.
Wherein, the value of the scheduled time and the first predetermined temperature does not do here specific restriction, can be entered according to actual conditions
Row is specific to be arranged.The work alternate scheduled time of such as the first pump and the second pump could be arranged to 1 hour, it is also possible to arrange
For half an hour.Also the first predetermined temperature, could be arranged to 10 degrees Celsius, it is also possible to be set to 12 degrees Celsius, and this will see electricity
The temperature value that specific electric device inside gas switch board can bear.
Two-way cooling system is in fact that the coolant in pipeline and radiator has two closed circuits, first closed circuit
For：First pump, pipeline, radiator and the first pump；Second closed circuit be：Second pump, pipeline, radiator and second
Pump.Because the direction of the first pump in two closed circuits and the second pump conveying coolant is contrary, so making in cabinet
Electric device can be cooled in time, it is ensured that the cooled equilibrium of cabinet, if single only with a kind of closed circuit, can
The cooled effect of a part of electric device can be caused bad, so using two-way cooling system, also improving electricity in cabinet
The job stability of device of air.Control system is additionally provided with cabinet, the setting of control system realizes whole electrical control cabinet

The area of the setting of individual pipeline many and cabinet interior contact as far as possible is big, but also to consider the installation position of electric device in cabinet
Put.It is structure as a whole because pipeline and cabinet are arranged, in order that cabinet seems that volume is unlikely to very big, this pipeline is as far as possible
It is set to partially flat.
Specifically, radiator is arranged on the top or bottom of cabinet, is specifically located at the top or bottom of cabinet,
Here specific restriction is not done.
Further, control unit controls the flow velocity of the first pump or the second pump according to the temperature value for receiving, if temperature
When value is between the second predetermined temperature and the first predetermined temperature, control unit makes the first pump or the flow velocity of the second pump increase to one
Predetermined speed, wherein, the second predetermined temperature is less than the first predetermined temperature.Arranging the purpose of this temperature range is, when in cabinet
Temperature close first predetermined temperature when, increase the speed of this coolant flow, improve cooling effectiveness.Second predetermined temperature value
Specific restriction is not done here yet.
Further, the mouth of entrance or the discharge for being used for coolant is provided with the pipeline for conveying coolant；Also
Including liquid level sensor, it is arranged on inside the pipeline of conveying coolant, for the liquid level of detection conveying coolant duct, and will
The level value for detecting is sent to control unit, and control unit judges in the pipeline of conveying coolant according to the level value for receiving
Coolant whether fill up pipeline.The setting of this opening and liquid level sensor is convenient for changing the coolant in cabinet, coolant
After after a while, possible cooling effect is just less good, or because coolant is for a long time using also can be slow
It is slow to reduce.
Specifically, also including cabinet door, the cell-phone number of a coded lock, coded lock and keeper is provided between cabinet door and cabinet
Association, to coded lock be input into keeper cell-phone number, mobile phone from coded lock to keeper send randomly generate coded lock it is close
Code.There is electro-insulating rubber pad between arranging between cabinet door and cabinet, be closing inside cabinet when cabinet door is closed.
Although embodiment of the present invention is disclosed as above, it is not restricted to listed in specification and embodiment
With, it can be applied to completely various suitable the field of the invention, for those skilled in the art, can be easily
Other modification is realized, therefore under the universal limited without departing substantially from claim and equivalency range, the present invention is not limited
