The water cooling device adopts a water cooling heat radiation mode, and can realize automatic operation (over-temperature automatic water replenishing). The water cooling device can realize recycling of cooling water, simultaneously output of four paths of cooling water, automatic cold water replenishing in case of over temperature of the cooling water in the device, and direct water supply for cooling under exceptional circumstances.
Description
Technical field
The utility model relates to mine anti-explosion frequency converter water cooling plant, is mainly used in the cooling of explosion-proof frequency converter under the coal mine.
Background technology
Along with the development of power electronic technology, power electronic equipment is to high-power, densification, lightweight development.The heat increase that is produced in the unit volume is very fast, and effectively area of dissipation but reduces relatively, because the reliability and the temperature of components and parts are inversely proportional to; Rate of breakdown raises and the exponent function relation growth with the components and parts temperature; Thermal accumlation can destroy components and parts, and heat fluctuation can cause solder joint loosening, therefore answers strict controlling parts temperature; Thereby need reliable heat dissipation technology, especially even more important for electrical apparatus for explosive atmospheres.
The water cooling heat dissipation method, ubiquity condensation phenomenon for guaranteeing the insulating properties of water-filled radiator, need prevent that condensation from appearring in radiator now.At present a lot of producers adopt the cooled plate inwall to smear antifogging coating, all can not tackle the problem at its root.
The utility model content
The purpose of the utility model is to the serious phenomenon of generating heat of explosion-proof frequency converter under the coal mine a kind of water cooling plant with favorable cooling effect to be provided.
The technical scheme of the utility model is: a kind of mine explosion-suppression frequency converter water cooling plant; Join through inlet channel and outlet conduit and mine flameproof and intrinsic safety type AC converter; Described water cooling plant set inside has water pump; Water pump joins with dividing the water box through ball valve, divides the water box to join through inlet channel and frequency converter, the water return outlet of frequency converter through outlet conduit and the water cooling plant formation loop that joins; Described water cooling plant is provided with direct-furnish water lines and water pipe.
Preferably: described direct-furnish water lines comprises with the direct-furnish waterpipe that divides the water box to join and is arranged at filter, the ball valve on the direct-furnish waterpipe.
Preferably: described water pipe comprises the moisturizing pipeline, and the moisturizing pipeline is provided with ball valve, and the water cooling plant set inside has temperature sensor, and temperature sensor and frequency converter join, the state of Frequency Converter Control ball valve.
The beneficial effect of the utility model is: this cooling device utilizes water cooling method, can realize automation mechanized operation: the excess temperature automatic water supplement.Can realize:
1. cooling water recycles;
2. four road cooling waters are exported simultaneously;

Embodiment
Embodiment below in conjunction with description of drawings the utility model:
A kind of mine explosion-suppression frequency converter water cooling plant; Join through inlet channel 1 and outlet conduit 2 and mine flameproof and intrinsic safety type AC converter 3; Described water cooling plant 9 set inside have water pump P; Water pump P is joined with dividing water box 4 through ball valve Q1, divides water box 4 to join through inlet channel 1 and frequency converter 3, and the water return outlet 5 of frequency converter 3 through outlet conduit 2 and water cooling plant joins and form the loop; Described water cooling plant is provided with direct-furnish water lines and water pipe.Described direct-furnish water lines comprises with the direct-furnish waterpipe 6 that divides water box 4 to join and is arranged at filter 8, the ball valve Q2 on the direct-furnish waterpipe 6, electrical ball valve M.Described water pipe comprises moisturizing pipeline 7, and moisturizing pipeline 7 is provided with ball valve Q3, and the water cooling plant set inside has temperature sensor t, and temperature sensor t and frequency converter 3 join, the state of frequency converter 3 control ball valves.
Water supply can be divided into dual mode:
(1) water cooling plant water, water pump is supplied with frequency converter 3 with the cooling water in the water cooling plant through ball valve Q1, branch water box 4, inlet channel 1, and the delivery port by frequency converter 3 flows back to through outlet conduit 2, cooling device water return outlet 5 again, forms circulating water cooling system.This kind mode should be noted that: the distance between a. water cooling plant 9 and the frequency converter 3 does not surpass the lift of water pump P; B. ball valve Q1 must open, close simultaneously ball valve Q2; C. cooling waters are not enough in the cooling device 9, or water temperature opens ball valve Q3 when too high, carry out moisturizing (temperature can be changed water after surpassing set point automatically, so generally speaking, ball valve Q3 need remain on open mode) through electrical ball valve M.
(2) open electrical ball valve M,, frequency converter 3 is carried out the direct-furnish water cooling through direct-furnish waterpipe 6.This kind mode should be noted that: open ball valve Q2, close ball valve Q1 and ball valve Q3 simultaneously.This kind mode also can be used when the water pump fault.
The above embodiment that lifts only uses to conveniently illustrating the utility model, and at the said technical scheme category of the utility model, the person of ordinary skill in the field does various simple deformation and modification, all should be included in the above claim.
Claims (3)
1. mine explosion-suppression frequency converter water cooling plant; Join through inlet channel and outlet conduit and mine flameproof and intrinsic safety type AC converter; It is characterized in that: described water cooling plant set inside has water pump; Water pump joins with dividing the water box through ball valve, divides the water box to join through inlet channel and frequency converter, the water return outlet of frequency converter through outlet conduit and the water cooling plant formation loop that joins; Described water cooling plant is provided with direct-furnish water lines and water pipe.
2. mine explosion-suppression frequency converter water cooling plant as claimed in claim 1 is characterized in that: described direct-furnish water lines comprises with the direct-furnish waterpipe that divides the water box to join and is arranged at filter, the ball valve on the direct-furnish waterpipe.
