Fig. 1 is the relational structure signal of the two-way cooling system and control system in electrical control cabinet of the present invention
Figure.
Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained all other without making creative work
Embodiment shall fall within the protection scope of the present invention.
The advantages of to make technical solution of the present invention, is clearer, and 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 include：Convey the pipeline 1 of coolant；Radiator 2, both ends are respectively connected to the two of pipeline 1
End forms a circulation loop, and radiator 2 makes to carry out the heat that heat exchange absorbs coolant between coolant and extraneous air
It sheds；First pump 3 and the second pump 4, being arranged in pipeline makes coolant be flowed in pipeline, and the first pump 3 and the
The direction of two pumps, 4 conveying coolant is opposite, and the first pump 3 and the second pump 4 work alternatively；Control system is additionally provided in cabinet
System, including：Control unit 5,3 and second pump 4 of the pump of radiator 2, first are connected to control unit 5；Detection unit 6 connects
Control unit 5 is connected to, detection unit 6 detects the open/close states of the electric device inside electrical control cabinet, and open/close states are passed
Send to control unit 5, control unit 5 according to the open/close states of the electric device received come control the pump of radiator 2, first 3 or
The keying of the pump of person second 4, wherein, every a predetermined time, the control of control unit 5 first pump 3 and the second pump 4 carry out alternately work
Make；Temperature sensor 7 is arranged on the inside of cabinet and is connected with control unit 5, for monitoring the 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 others can play the liquid of cooling effect, not do herein specific
Restriction.
Wherein, the value of predetermined time and the first predetermined temperature does not do specific restriction herein, can according to actual conditions into
The specific setting of row.Such as first pump and second pump the work alternate predetermined time could be provided as 1 hour, can also set
For half an hour.Also the first predetermined temperature could be provided as 10 degrees Celsius, may be set to be 12 degrees Celsius, this will see electricity
The temperature value that specific electric device inside gas switch board can be born.
Two-way cooling system is that there are two circulation loop, first circulation loops for coolant in pipeline and radiator in fact
For：First pump, pipeline, radiator and the first pump；Second circulation loop be：Second pump, pipeline, radiator and second
Pump.Since the direction that the first pump in two circulation loops and the second pump convey coolant is opposite, so making in cabinet
Electric device can be cooled in time, ensure that cabinet is cooled equilibrium, can if single only with a kind of circulation loop
The effect that a part of electric device can be caused to be cooled is bad, so using two-way cooling system, also improves electric in cabinet
The job stability of device of air.Control system is additionally provided in cabinet, the setting of control system realizes entire electrical control cabinet
Automation, when the electric device in cabinet is started to work, cooling system also begins to work, do not need to go again individually to go again
It is operated.The setting of temperature sensor ensure that the temperature in electrical control cabinet is maintained in a predetermined temperature range, will not
Electric device is damaged due to temperature is excessively high.
Specifically, the pipeline of conveying coolant is arranged on the two side and rear wall inside cabinet, wherein, convey coolant
Pipeline and cabinet be structure as a whole, the electric device in pipeline and cabinet is isolation, conveys the pipeline of coolant in S shapes,
In order to improve cooling effect, the pipeline for making conveying coolant that can be as possible is longer；Conveying coolant duct duct wall be in
Undaform or equidistant male-type are so that the pipeline of conveying coolant increases with the area of cabinet interior contact.Wherein, this
The setting of a pipeline is mostly big with the area of cabinet interior contact as far as possible, but also to consider the installation position of electric device in cabinet
It puts.Since pipeline and cabinet setting are structure as a whole, in order to which cabinet is made to seem that volume is unlikely to very big, this pipeline is as far as possible
It is set as partially flat.
Specifically, radiator is arranged on the top or bottom of cabinet, the top or bottom of cabinet are specifically located at,
Here specific restriction is not done.
Further, control unit is according to the first pump of temperature value control received or the flow velocity of the second pump, if temperature
When value is between the second predetermined temperature and the first predetermined temperature, control unit makes the first pump or the second flow velocity pumped increase to one
Predetermined speed, wherein, the second predetermined temperature is less than the first predetermined temperature.The purpose for setting this temperature range is, when in cabinet
Temperature close to the first predetermined temperature when, increase the speed of this coolant flow, improve cooling efficiency.Second predetermined temperature value
Specific restriction is not done herein yet.
Further, it conveys and a mouth for entrance or the discharge of coolant is provided on the pipeline of coolant；Also
Including liquid level sensor, it is arranged on inside the pipeline of conveying coolant, for detecting the liquid level of conveying coolant duct, and will
The level value detected is sent to control unit, and control unit is judged according to the level value received in the pipeline of conveying coolant
Coolant whether fill up pipeline.The setting of this opening and liquid level sensor is convenient for changing the coolant in cabinet, coolant
Using after a period of time, possible cooling effect is just less good or since coolant much time using also can be slow
It is slow to reduce.
Specifically, further including cabinet door, the cell-phone number of a coded lock, coded lock and administrator is provided between cabinet door and cabinet
Association, to coded lock input administrator cell-phone number, mobile phone from coded lock to administrator transmission randomly generate coded lock it is close
Code.There is electro-insulating rubber pad between being set between cabinet door and cabinet, be closing when cabinet door is closed, inside cabinet.
Although the embodiments of the present invention have been disclosed as above, but its be not restricted in specification and embodiment it is listed
With it can be fully applied to various fields suitable for the present invention, for those skilled in the art, can be easily
Realize other modification, therefore without departing from the general concept defined in the claims and the equivalent scope, it is of the invention and unlimited
