Abstract
A heat-dissipating system of a large-power converter comprises an equipment cabinet body, blower fans, a heat exchanger and an equipment heating body. The equipment heating body comprises power modules, a DC bus fuse wire, an input reactor and an output reactor. The power modules are arranged under the blower fans; and each power module is provided with an upper plate and a lower plate, and the power module itself serves as an air channel. The advantages of the heat-dissipating system are that the whole cabinet body is fully closed, thereby preventing external dusts and salt mists from internally influencing a converter device; the power modules are independently packaged, internal devices of the power modules are arranged on a cooling plates, so that the majority of loss generated by the devices is taken away by cooling liquid; and the inlet and the outlet of the cooling plate are positioned outside the power module package, thereby avoiding module internal power off due to pipeline leakage.
Description
Technical field
The present invention relates to a kind of cooling system, in particular for the cooling system of high-power converter.
Technical background
Along with the development of wind electric converter technology, the power grade of wind electric converter is more and more higher.High power level and high power density become the trend of current transformer development, and the heat dissipation problem of current transformer becomes a technical bottleneck thereupon.
At present heat radiation major way: natural heat dissipation, forced air cooling and force liquid cooling etc.The current transformer of natural heat dissipation is because the efficiency of natural heat dissipation is low, thereby causes current transformer bulky, and cost is larger.The current transformer of forced air cooling adopts the heat radiation of inner air and outer air exchanged form, thereby the quality of surrounding air is larger on current transformer impact, especially in dust storm and the larger region of salt fog, forced air cooling is brought the material such as dust and salt fog into current transformer inside by inner air and outer air exchange meeting, thereby current transformer internal components is exerted an influence, as the insulation to current transformer internal components produces corrosion etc.If employing forces its heat dissipation pipeline of current transformer of liquid cooling to leak, may cause device interior short circuit, cause damage.
Summary of the invention
The invention provides a kind of effective cooling system and meet the demands with the temperature rise that guarantees current transformer, guarantee afterwards the working life of current transformer.
Technical scheme of the present invention: a kind of high-power converter cooling system, comprise equipment cabinet, blower fan, heat exchanger, equipment heating body, described heater comprises power model, DC bus fuse, input reactance device and out put reactor, described power model is arranged on the below of blower fan, described power model does not have upper and lower plates, and itself is as air channel.
Described power model adopts individual packages design, and power model internal components is arranged on inner cold drawing, and most of heat of its generation is taken away by cooling fluid, and fraction is taken away by air channel is distinguished and admirable.
Described blower fan, DC bus fuse, input reactance device, out put reactor, heat exchanger, power model are suitable.
The sealing of described equipment cabinet, adopts air-cooled and liquid cooling mode to dispel the heat, and the blower fan that is positioned at power model top makes inner cabinet air circulation, and the heat of power model is taken away by the cooling fluid of the heat exchanger of its below.
Described blower fan quantity is 2, and power model quantity is 3.
Advantage of the present invention: whole cabinet seals completely, prevents extraneous dust, the impact of salt fog on current transformer device interior; Power rate module adopts individual packages design, and in it, device is arranged on inner cold drawing, and most of loss that device produces is taken away by cooling fluid, and the import and export of cold drawing are positioned at outside module package, can avoid causing the inner power-off of power model because pipeline is revealed.The present invention adopts method air-cooled and that liquid cooling combines, the centrifugal blower that is positioned at module top makes inner cabinet air circulation, power model device to be recycled air cooling, airborne heat is taken away by the cooling fluid of the heat exchanger of power model bottom, the leakage of air-water heat exchanger cooling fluid simultaneously can not affect the normal work of other electrified bodies in cabinet, guarantees to enter the air themperature of module lower than the temperature of rack cavity simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is front view of the present invention.
In figure, the 1st, blower fan, the 2nd, power model, the 3rd, heat exchanger, the 4th, equipment cabinet, the 5th, DC bus fuse, the 6th, input reactance device, the 7th, out put reactor.
Embodiment
As Fig. 1, a kind of high-power converter cooling system comprises equipment cabinet 4, blower fan 1, heat exchanger 3, equipment heating body, described heater comprises power model 2, DC bus fuse 5, input reactance device 6 and out put reactor 7, wherein power model 2 is arranged on the below of blower fan 1, and power model 2 does not have upper and lower plates, and itself is as air channel.As Fig. 2, the quantity of power model is 3, and blower fan quantity is 2.Power model 2 adopts individual packages design, its internal components is arranged on inner cold drawing, the water inlet of cold drawing is positioned at outside power module package, most of loss that power model produces is taken away by cooling fluid, sub-fraction loss meeting, by distinguished and admirable the taking away in air channel, is then taken to outside cabinet by air-water heat exchanger.
Described blower fan, DC bus fuse, input reactance device, out put reactor, heat exchanger, power model are suitable, thereby the path of the air circulation process forming is: blower fan 1-DC bus fuse 5-input reactance device 6-out put reactor 7-heat exchanger 3-power model 2.Certainly, the arrangement of the device in cabinet is put and can be designed according to actual needs.
Described equipment cabinet seals to prevent dust and the impact of salt fog on device interior, it adopts air-cooled and liquid cooling mode to dispel the heat, the blower fan that is positioned at power model top makes inner cabinet air circulation, and the heat of power model is taken away by the cooling fluid of the heat exchanger of its below.
