For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of air water cooling converter plant, comprise frequency-converter power cabinet, frequency conversion power unit, frequency conversion cooling fan, frequency conversion power unit is positioned at the front portion of frequency-converter power cabinet, in upper and lower three layers of distribution; It is characterized in that, this converter plant adopts cooling liquid and air-cooled two kinds of radiating modes; The air water cooling radiator arranged by frequency-converter power cabinet inside and the frequency conversion cooling fan at cabinet top are dispelled the heat simultaneously; Air water cooling radiator is positioned at the rear portion of frequency-converter power cabinet, the dead astern of three layers of frequency conversion power unit; Frequency conversion cooling fan is positioned at the top of frequency-converter power cabinet, directly over air water cooling radiator; Cooling liquid is in pipe interior sealing and circulating, and air water cooling radiator is provided with cooling liquid import and is connected with outlet conduit with cooling liquid water inlet pipe road respectively with liquid outlet.
Compared with prior art, the utility model has the advantages that:
1) cooling blast bottom in and top out, flows to rationally distributed, and air stream and cooling liquid flow to approximate inverse stream, and logarithmic temperature difference is large, and cooling effectiveness is high;
2) due to air water cooling, but the system integration is inner in frequency converter cabinet body, is combined into unified entirety with frequency converter.Therefore easy for installation, be beneficial to transport.
3) circuit water route is arranged apart.Effectively can prevent the danger of high-tension electricity.There is high reliability.
4) circulating cooling, improves the heat exchange efficiency of cooling system.
5) there is not the restriction of transmission range in distributing pipe line, and volume is little.
6) adopt extraneous ventilating and cooling under Cooling water system failure condition, the equipment that do not affect runs.

Embodiment
Below in conjunction with accompanying drawing, technology contents of the present utility model is described in further detail.
See Fig. 1, Fig. 2, Fig. 3, a kind of air water cooling converter plant, comprise frequency-converter power cabinet 1, frequency conversion power unit 2, frequency conversion cooling fan 4, frequency conversion power unit 2 is positioned at the front portion of frequency-converter power cabinet 1, in upper and lower three layers of distribution; It is characterized in that, this converter plant adopts cooling liquid and air-cooled two kinds of radiating modes; The air water cooling radiator 3 arranged by frequency-converter power cabinet 1 inside and the frequency conversion cooling fan 4 at cabinet top are dispelled the heat simultaneously; Air water cooling radiator 3 is positioned at the rear portion of frequency-converter power cabinet 1, the dead astern of three layers of frequency conversion power unit 2; Frequency conversion cooling fan 4 is positioned at the top of frequency-converter power cabinet 1, directly over air water cooling radiator 3; Cooling liquid is in pipe interior sealing and circulating, and water-filled radiator is provided with cooling liquid import and liquid outlet.
This air water cooling converter plant comprises the parts such as transducer power unit 2, frequency conversion cooling fan 4, air water cooling radiator 3 and relevant water circuit system.This air water cooling converter plant utilizes cooling liquid, is dispelled the heat by air water cooling radiator 3 in cabinet and frequency-charger cabinet top blower fan 4 simultaneously.The temperature of frequency converter cabinet body inside is reduced rapidly.
Air water cooling radiator 3 is installed to frequency converter cabinet body inside by this air water cooling converter plant, and described air water cooling radiator inside is provided with fluid passage, can complete air and liquid two kinds of heat exchange modes.Air water cooling radiator 3 is positioned at the dead astern of transducer power unit 2, is combined into unified entirety with frequency converter.Wherein circuit water route is arranged apart.Easy for installation, be beneficial to transport.In this air water cooling converter plant, all devices of internal watercourses system all adopt metal or alloy material.
Seeing Fig. 4, is that the cooling channel of air water cooling converter plant flows to schematic diagram.The direction of arrow be turnover frequency-converter power cabinet 1 aeration flow to.Cold wind enters cabinet from transducer power cabinet 1 front portion, produces hot blast after being dispelled the heat by transducer power unit 2.Hot blast flows back to indoor by frequency conversion cooling fan 4 after air water cooling radiator 3 dispels the heat, then enters cabinet inside from frequency converter cabinet body 1 front portion, realizes the effect of air-out on advancing air.
The cooling liquid that temperature is lower enters air water cooling radiator 3 internal fluid passages by frequency converter outside, carries out heat exchange exchange with the hot blast of process.Flowed out air water cooling radiator 3 by the cooling liquid after heating by relevant water circuit system, cool in outside, the cooling liquid through cooling enters air water cooling radiator 3 again through water pump, cools frequency converter cabinet body recirculate air inside.
This air water cooling converter plant, utilizes cooling liquid, is dispelled the heat by air water cooling heat abstractor in cabinet and frequency-charger cabinet top blower fan simultaneously.The heat that frequency conversion power unit is discharged directly can be lowered the temperature process.Improve the heat exchange efficiency of cooling system, meet the requirement that frequency converter runs for environment.Better ensure that operating temperature environment good in Transducer Room.
