Abstract
The utility model discloses a water-cooling radiating structure for a three-level inverter, belonging to the technical field of inverters. The water-cooling radiating structure of the three-level inverter comprises a water-cooling unit frame and three inverters and is characterized by further comprising water filling pipes, soft pipes and water-cooling plates, wherein the water filling pipes are installed inside the water-cooling unit frame and near the lower part; two water filling pipes are provided, namely a water inlet pipe and a water outlet pipe; the water-cooling plates are installed inside the inverters; three soft pipes are led out of the water inlet pipe and communicated with water inlets of the three water-cooling plates; and three soft pipes are led out of the water outlet pipe and communicated with water outlets of the three water-cooling plates. The water-cooling radiating structure of the three-level inverter has the advantages that the radiating effect is good; and the radiating problem of a large-power three-level double-feedback frequency-inverting system can be effectively solved.
Description
Technical field
The utility model relates to a kind of frequency converter product, relates in particular to a kind of three-level converter water-cooling structure, belongs to the frequency converter field.
Background technology
Frequency converter will produce certain power consumption as a kind of current transformer in running.Because use device different, control mode is different, different brands, the power consumption that frequency converter produced of different size also is not quite similar.Data shows that the power consumption of frequency converter is generally 4 ~ 5% of its capacity.Wherein inversion partly accounts for 50%, and rectification and DC loop are about 40%, and control and protective circuit are 5 ~ 15%.When device temperature reduces by 10 ℃, one times of the reliability growth of device.How to handle the heat radiation of frequency converter, reduce temperature rise, improve the reliability of device, thereby prolong the useful life of equipment.The radiating mode of frequency converter is divided into following several kinds: natural heat dissipation, forced air cooling.Frequency converter for low capacity is generally selected the natural heat dissipation mode for use, and its environment for use is answered the well-ventilated, does not have to be prone to adhere to dust and drift.The capacity of the general frequency converter of forced air cooling can be accomplished from tens to hundreds of kVA.But along with the exploitation of big-power transducer, when the frequency conversion power consumption reached a constant volume, the structure of air blast cooling can't satisfy the radiating requirements of big power consumption element technically.
Summary of the invention
To the problem that above-mentioned prior art exists, the utility model provides a kind of three-level converter water-cooling structure, has good heat dissipation effect, effectively solves the effect of high-power three level double-fed frequency conversion system heat dissipation problems.
To achieve these goals, the technical scheme of the utility model employing is: a kind of three-level converter water-cooling structure comprises the water-cooled unit framework; Three frequency converters is characterized in that, also comprise water injection pipe, flexible pipe and cooled plate; Water injection pipe is installed in the inside of water-cooled unit framework by following; Water injection pipe has two, is respectively water inlet pipe and outlet pipe, and cooled plate is installed in frequency converter inside; Water inlet pipe is drawn the water inlet that three flexible pipes are switched to three cooled plate, and outlet pipe is drawn the delivery port that three flexible pipes are switched to three cooled plate.
The below of said three frequency converters is installed a blower fan respectively.
Said cooled plate is a waterproof sealing structure.
The beneficial effect of the utility model is: good heat dissipation effect, effectively solve high-power three level double-fed frequency conversion system heat dissipation problems.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the cooled plate sketch map of the utility model;
Among the figure: 1, water-cooled unit framework, 2, frequency converter, 4, flexible pipe, 5, cooled plate, 6, water inlet pipe, 7, outlet pipe, 8, water inlet, 9, delivery port, 10, blower fan.
Embodiment
To combine accompanying drawing that the utility model is described further below.
As depicted in figs. 1 and 2, the utility model comprises 1, three frequency converter 2 of water-cooled unit framework, water injection pipe, flexible pipe 4 and cooled plate 5; Water injection pipe is installed in the inside of water-cooled unit framework 1 by following; Water injection pipe has two, is respectively water inlet pipe 6 and outlet pipe 7, and cooled plate 5 is installed in frequency converter 2 inside; Water inlet pipe 6 is drawn the water inlet 8 that three flexible pipes 4 are switched to three cooled plate 5, and outlet pipe 7 is drawn the delivery port 9 that three flexible pipes 4 are switched to three cooled plate 5; The below of three frequency converters 2 is installed a blower fan 10 respectively; Cooled plate 5 is a waterproof sealing structure.
The utility model gets into flexible pipe 4 with current through water inlet pipe 6 through the pressure of external water circulation, gets into the cooled plate 5 of frequency converter 2 inside again, and cooled plate 5 is a waterproof sealing structure, and current lower the temperature for cooled plate 5, and cooled plate 5 is lowered the temperature to frequency converter then.Current get into outlet pipe 7 again with the delivery port 9 entering flexible pipes 4 of heat through cooled plate 5, and heat is taken away.A blower fan all is set respectively below three frequency converters, can prevents frequency converter, cause the surface that condensation is arranged, whole frequency converter is caused damage because temperature descends.Owing to adopted water-cooling, can effectively solve high-power three level double-fed frequency conversion system heat dissipation problems.
