Abstract
The utility model discloses a high-power converter cooling system, which comprises an equipment cabinet body, an air blower, a heat exchanger, and equipment heating bodies, wherein the equipment heating bodies comprise a power module, a direct current bus fuse, an input reactor and an output reactor; the power module is arranged below the air blower; and the power module has no upper and lower boards, and the power module per se serves as an air duct. The high-power converter cooling system has the advantages that the whole cabinet body is sealed totally, such that dust and salt mist outside can be prevented from influencing the inner part of the converter equipment; the power module adopts independent package design, the inner components are mounted on the inner cooling board, most loss generated by the components are taken away by cooling liquid, the inlet and the outlet of the cooling board are located outside the module package, and power failure inside the module due to leakage of the pipeline can be prevented.
Description
Technical field
The utility model 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 then becomes a technical bottleneck thereupon.
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 efficient 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 the current transformer impact, especially in dust storm and the larger zone of salt fog, forced air cooling is brought the materials such as dust and salt fog into current transformer inside by inner air and outer air exchange meeting, thereby the current transformer internal components is exerted an influence, produce corrosion etc. such as the insulation to the current transformer internal components.If employing forces its heat dissipation pipeline of current transformer of liquid cooling to leak, may cause the device interior short circuit, cause damage.
The utility model content
The utility model provides a kind of effective cooling system to meet the demands with the temperature rise that guarantees current transformer, guarantees afterwards the working life of current transformer.
The technical solution of the utility model: a kind of high-power converter cooling system, comprise the equipment cabinet, blower fan, heat exchanger, equipment heating body, described heater comprises power model, the 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 the air channel.
Described power model adopts the individual packages design, and the power model internal components is installed in inner cold drawing, and most of heat of its generation is taken away by cooling fluid, and fraction is taken away by the air channel is distinguished and admirable.
Described blower fan, dc bus fuse, input reactance device, out put reactor, heat exchanger, power model are suitable.
Described equipment cabinet sealing is adopted air-cooled and the liquid cooling mode is dispelled 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.
The utility model advantage: whole cabinet complete closed prevents that extraneous dust, salt fog are on the impact of current transformer device interior; Power rate module adopts the individual packages design, and device is installed on the inner cold drawing in it, 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 the module package, can avoid causing the inner outage of power model because pipeline is revealed.The utility model 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 be recycled air cooling, airborne heat is taken away by the cooling fluid of the heat exchanger of power model bottom, the simultaneously leakage of air-water heat exchanger cooling fluid can not affect the normal operation of other electrified bodies in the cabinet, and the air themperature that guarantees simultaneously to enter module is lower than the temperature of rack cavity.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is front view of the present utility model.
Among the 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
Such 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 the air channel.Such as Fig. 2, the quantity of power model is 3, and blower fan quantity is 2.Power model 2 adopts the individual packages design, its internal components is installed on the inner cold drawing, the water inlet of cold drawing is positioned at outside the power module package, most of loss that power model produces is taken away by cooling fluid, then sub-fraction loss meeting is taken to outside the cabinet by air-water heat exchanger by distinguished and admirable the taking away in the air channel.
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 that forms 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 the cabinet is put and can be designed according to actual needs.
Described equipment cabinet seals to prevent that dust and salt fog are on the impact of device interior, it adopts air-cooled and the liquid cooling mode is dispelled 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.
