Background technology
Along with developing rapidly of power electronic technology, frequency converter, with its remarkable performance and advantage, is widely used in recent years and promotes in every profession and trade.Although frequency converter is one speed regulating device very efficiently, but be in operation, still there is the loss of 2%-4% left and right, these losses all become heat, and particularly mining frequency converter, in order to ensure the safety of down-hole, mining frequency converter is all contained in explosion-proof housing, the heat producing is difficult to distribute more, how these heats is brought out smoothly from frequency converter explosion-proof casing, is a very important problem in mine-used frequency-converter design.
Following several mode is mainly taked in the heat radiation of current mine-used frequency-converter: a kind of mode that adopts housing natural heat dissipation or simple wind-cooling heat dissipating, this mode is too original, radiating rate is slower, radiating effect is also difficult to reach instructions for use, in order to protect mine-used frequency-converter not damaged, just need to shut down heat radiation, make the mine-used frequency-converter cannot long time continuous working, and then affect other work of down-hole; Another kind is to adopt the underground water on ore deposit to carry out cooling to mine-used frequency-converter, allow these underground water flow into the cooling water channel of frequency conversion housing, heat is taken away, then go out mine along row of conduits, these underground water are rich in mineral matter, can corrode the cooling water channel of frequency converter shell, have a strong impact on the useful life of frequency converter, cause the waste of water simultaneously.
Utility model content
The utility model is for the radiating mode of above-mentioned mine-used frequency-converter, and radiating rate is slow, and radiating effect is poor; make equipment downtime, cannot continuous operation, underground water corrosion frequency converter; affect the frequency converter life-span, cause the problems such as water resource waste, designed a kind of cooling device of new explosion-isolating mine frequency converter.
The cooling device of explosion-isolating mine frequency converter of the present utility model, comprise sky water interchanger and the water storage box that cooling fluid is housed, water storage box is connected with the water inlet that the cooling water channel of frequency converter explosion-proof casing arranges by input pipe, the delivery port that the cooling water channel of frequency converter explosion-proof casing arranges is connected with empty water interchanger by efferent duct, empty water interchanger is connected with water storage box by return duct again, on input pipe, be provided with water pump, break valve and meter, meter can detect inner pipe water pressure, water temperature and water level, meter is electrically connected with water pump, the housing of both sides hollow out before and after empty water interchanger comprises, both sides, front and back in housing are separately installed with copper pipe radiator and cool breeze are blowed to the radiator fan of copper pipe radiator, copper pipe radiator comprises that copper pipe and interval are arranged on the some metal blades on copper pipe, return duct and efferent duct are all communicated with the copper pipe of copper pipe radiator, cooling water in water storage box is pure water.
Preferably, the water inlet of described copper pipe radiator copper pipe setting is positioned at top, delivery port is positioned at bottom, and copper pipe is snakelike from top to bottom arranges, and efferent duct is connected with the water inlet of copper pipe, and return duct is connected with the delivery port of copper pipe.
The beneficial effects of the utility model are: the cooling device of explosion-isolating mine frequency converter utilizes cistern, empty water interchanger and pipeline to form liquid circulation; the heat of the frequency converter absorbing in cooling water is delivered in air by empty water interchanger; and leave mine by the ventilating system of down-hole; can more effective faster the heat in frequency converter explosion-proof casing be taken out of; make the temperature constant of frequency converter; need not allow frequency converter shut down, it can be worked long hours, ensure underground work efficiency.Cooling device is the cooling water circulation of a sealing, the amount that cooling water uses is certain, and can not reduce after long-time use, need not augment cooling water, can not cause the waste of cooling water, cooling water adopts pure water, high purity, impurity is few, can not corrode the explosion-proof casing of frequency converter, has ensured the useful life of frequency converter.The copper pipe of copper pipe radiator is snakelike and arranges, increase area of dissipation, and cooling fluid upper entering and lower leaving, making in copper pipe the heat of cooling fluid be distributed as temperature from top to bottom reduces gradually, allow hotter ECL in top, prevent the hot air rising that hotter cooling fluid gives out, and then affect the dissipation of heat of superposed cooling fluid, ensured radiating effect.

The overall structure figure of the cooling device that accompanying drawing 1 is explosion-isolating mine frequency converter;
Accompanying drawing 2 is the structure chart of empty water interchanger;
The structure chart that accompanying drawing 3 is copper pipe radiator.
Embodiment
The cooling device of explosion-isolating mine frequency converter of the present utility model, as shown in Figures 1 to 3, comprise sky water interchanger 1 and the water storage box 2 that cooling fluid is housed, water storage box 2 is connected with the water inlet 4 that the cooling water channel of frequency converter arranges by input pipe 3, the delivery port 5 that the cooling water channel of frequency converter arranges is connected with empty water interchanger 1 by efferent duct 6, and empty water interchanger 1 is connected with water storage box 2 by return duct 7 again.
On input pipe 3, be provided with water pump 8, break valve 9 and meter 10, meter 10 can detect inner pipe water pressure, water temperature and water level.
The housing 11 of both sides hollow out before and after empty water interchanger 1 comprises, both sides, front and back in housing 11 are separately installed with copper pipe radiator 12 and cool breeze are blowed to the radiator fan 13 of copper pipe radiator 12, copper pipe radiator 12 comprises that copper pipe 14 and interval are arranged on the some metal blades 15 on copper pipe 14, return duct 7 and efferent duct 6 are all communicated with the copper pipe 14 of copper pipe radiator 12, and the cooling water in water storage box 2 is pure water.
The water inlet 16 that copper pipe radiator 12 copper pipes 14 arrange is positioned at top, delivery port 17 is positioned at bottom, and copper pipe 14 is snakelike arranging from top to bottom, and efferent duct 6 is connected with the water inlet 16 of copper pipe 14, and return duct 7 is connected with the delivery port 17 of copper pipe 14.
