The water/wind cooling system has the advantages of effectively avoiding the dewing of cooling buses and elements due to big difference between the water temperature and the temperature in the rectifying cabinet and preventing short circuits in the rectifying device.
Description
Affiliated technical field
The utility model relates to rectifier water-air cooling system, particularly relates to the water-air cooling system with anti-dewing function, and it is used to prevent because the big temperature difference makes cooling bus and element dewfall.
Background technology
Power-supply rectifying device in the electrolytic aluminium factory commutation system particularly type of cooling of high-power rectifying device mainly contains two kinds: a kind of is to adopt water-water heat exchange cooler, be to use pure water between cooler and the fairing as cooling medium, the negative water of cooling is the cooling water that is provided by the pump station of recirculation water of concentrating, this recirculated cooling water cools off pure water by the plate type heat exchanger in water-water cooler, the advantage of this kind cooling system is that the low-temperature cooling water of cooling cools off by the cooling medium of plate type heat exchanger to fairing, cooling is with water at low temperature not directly the water-cooled bus and the components and parts of contact electrification, shortcoming is, it is that a pump station of recirculation water is a plurality of Rectification Power Factor coolings by localized ducting that water is paid in cooling, in case circulation cooling pumping plant or central water supply pipeline fault are cut off the water supply, will cause whole commutation system to have a power failure.Another kind is, each fairing adopts independently one group of water-air-cooling device, advantage is that each Rectification Power Factor is provided with independently cooling system, the pump station of recirculation water and the aqueduct of concentrated special use have been saved, the cooling device fault only influences a Rectification Power Factor, do not influence the operation of other Rectification Power Factor, can not cause the power failure of complete series, shortcoming is that water-wind heat exchanger is installed in outdoor, cooling medium directly is cooled, if handle dewfall on bad water-cooled bus that very easily causes water temperature to cross to hang down in fairing and the element, cause the cabinet internal short-circuit, particularly for the bigger cold district of indoor/outdoor temperature-difference.
The utility model content
The technical problem that the utility model solves provides a kind of water-air cooling system with anti-dewing function, be used for solving and be installed in outdoor when water-wind heat-exchange system, cooling medium directly is cooled, when indoor/outdoor temperature-difference is big, cause water temperature to cross to hang down dewfall on water-cooled bus in fairing and the element, prevent to cause the fairing internal short-circuit.
In order to solve the problems of the technologies described above, the utility model is achieved in that the water-air cooling system with anti-dewing function, it comprises inner loop pipeline, the heat exchanger that is connected with inner loop pipeline and moisture trap and rectifier cabinet, it is characterized in that on the inlet pipeline of rectifier cabinet, being provided with the load water intaking valve, the load back-water valve (BWV) is set on the water return pipeline of rectifier cabinet, on the inlet pipeline of rectifier cabinet and the pipeline between the water return pipeline, the closed cycle stop valve is set, electric heater unit is installed on inner loop pipeline.
Described electric heater unit is a resistive heating device.
The gas pressure relief valve is installed on the described moisture trap.
Described gas pressure relief valve is installed in the rear portion of moisture trap.
Advantage of the present utility model and innovative point are as follows:
The utility model reaches water temperature by inner loop when unit has a power failure long or send electricity for the first time or when being higher than indoor temperature (being advisable with 25～30 ℃), close electric heater unit and closed cycle stop valve then, open load back-water valve (BWV) and load water intaking valve, carry out the work cool cycles, effectively avoid excessive temperature differentials in water temperature and the rectifier cabinet and caused cooling off bus and element dewfall, prevented to cause the fairing internal short-circuit.

Specific implementation method
Below in conjunction with accompanying drawing the utility model is described in further details, but protection domain of the present utility model is not limit by embodiment.
As shown in Figure 1, it is as follows to the utlity model has the structure of water-air cooling system of anti-dewing function: it comprises inner loop pipeline 11; The heat exchanger 1 that is connected with inner loop pipeline 11, moisture trap 2, deionizer 3 and water circulating pump 5; And rectifier cabinet 7.Wherein on the inlet pipeline of rectifier cabinet 7, establish a load water intaking valve 9, establish a load back-water valve (BWV) 8 on the water return pipeline of rectifier cabinet 7, on the inlet pipeline of rectifier cabinet 7 and the pipeline between the water return pipeline, a closed cycle stop valve 10 is set, one electric heater unit 6 is installed on inner loop pipeline 11, electric heater unit 6 can adopt resistive heating device, as long as it can heat recirculated water, a gas pressure relief valve 4 is installed at rear portion at moisture trap 2, and gas pressure relief valve 4 is used to solve recirculated water and contacts the problem that water quality is degenerated with air.
Operation principle of the present utility model is as follows: by inner loop water temperature is reached when unit has a power failure long or send electricity for the first time or when being higher than indoor temperature (being advisable with 25～30 ℃), close electric heater unit 6 and closed cycle stop valve 10 then, open load back-water valve (BWV) 8 and load water intaking valve 9, carry out the work cool cycles, dewfall to avoid water temperature and indoor (in the rectifier cabinet) excessive temperature differentials.
