Description
Technical field
The present invention relates to large-scale three-phase convertor equipment, particularly a kind of great power conversion circuit plant capacity module group.
Background technology
High power contravariant system of the prior art such as China Patent No. is the air-cooled power inverter power cabinet with large of a kind of high radiator structure disclosed in the patent of invention of 200710029765.8; comprise cabinet and the power cell being arranged on cabinet inner chamber; the relative both sides of cabinet are provided with shutter, and the top of cabinet is provided with air exhauster; Power cell is spot distribution or strip distribution at the inner chamber of cabinet, makes to form gap between power cell, and the heat dissipation wind channel of these gaps and power cell forms air channel at the inner chamber of cabinet, and the inlet scoop of air exhauster is just to air channel.
And for example China Patent No. is the heat pipe type power module of high-efficient wind power frequency converter disclosed in the patent of invention of 200910075267.6, comprise substrate, substrate rear portion is fixed with heat-pipe radiator, the bottom of heat-pipe radiator is provided with hair-dryer, top is provided with air inducing pipeline, is provided with air exhauster in air inducing pipeline; It is in running, the heat that power device sends is transmitted on heat-pipe radiator by substrate, bottom heat-pipe radiator hair-dryer effect under, heat is dispersed in air inducing pipeline, afterwards in air inducing pipeline air exhauster effect under, heat is extracted into rapidly frequency-charger cabinet external body.
Above-mentioned two kinds of power cabinets are generally formed by multiple power model is stacked, each power model realizes A, B, the unsteady flow of C tri-phase places, and often comprise several IGBT, 1 piece of stack bus bar, 1 module radiator and some electric capacity, in such systems, the unsteady flow of ABC tri-phase places will be exported by same stack bus bar, the thermal losses that unsteady flow produces will by same heat sink radiates, therefore, each power model adopts same air duct radiation, therefore, this kind of air-cooled form fetch is generally longitudinally and longer, and the air exhauster that power is larger need be adopted, thus energy consumption is larger.
Also has a kind of power model group, its three power models are also longitudinally be arranged on same stack bus bar, and when power requirement needs two groups of power model groups time, the IGBT assembly of these two groups of power model groups is oppositely arranged, and side is between the two provided with cooling fan, this blower fan dispels the heat to two groups of power model groups simultaneously, and this kind of radiating mode is that laterally fetch is shorter, but owing to being dispel the heat to two groups of power models simultaneously, therefore, the power requirement of blower fan is higher, and energy consumption is larger.
In prior art, because three power models all concentrate on a block stack bus bar, the calorie source close together of three power models, and cooled by same radiator and air channel, therefore, need the cooling fan of higher-wattage; The present invention is due to three separate settings of power model, therefore, true heat gain value is about less than 1/3 of prior art total amount, and each power model is provided with air channel and cooling fan, thus adopt the gross power of cooling fan much less than of the prior art.
As preferably of the present invention, each power model comprises the IGBT assembly being positioned at corresponding stack bus bar top, the capacitance component being positioned at stack bus bar bottom.
In lengthwise position, in prior art, capacitance component is generally all arranged at cabinet top, because heat all can to external radiation, particularly upwards radiation, therefore, particularly the IGBT assembly of below also can have larger thermal radiation impact to capacitance component, and therefore, capacitance component heat radiation of the prior art is poor; The present invention due to each power model be independent setting, the heat radiation impact between the power model of therefore out of phase is less, and due to the above-mentioned distribution form of capacitance component and IGBT assembly, make capacitance component be subject to IGBT assembly thermal-radiating affect less.
As preferably of the present invention, IGBT assembly and the capacitance component of described each power model are positioned at the same side of corresponding stack bus bar.
Above-mentioned setting of the present invention, be then conducive to making the volume of power model group more compact, is conducive to the volume reducing power model group.
As preferably of the present invention, described three power models laterally distribute side by side; Each power model also comprises for the radiator to IGBT assembly radiating; Wherein the radiator of a pair adjacent power module distributes in opposite directions.
Above-mentioned setting, two adjacent power modules that radiator is distributed in opposite directions can use one group of blower fan to dispel the heat simultaneously, and two radiators in opposite directions just in time form one for air-cooled air channel; When unsteady flow power needs two groups of power model groups, although the present invention needs three groups of blower fans to dispel the heat, and though prior art only needs two groups of blower fans, but because in prior art, one group of blower fan needs to dispel the heat to three power models simultaneously simultaneously, so its required heat radiation total amount is about of the present invention 150%, simultaneously because stack bus bar area used in the prior art is about 3 times of the present invention, so the air-cooled stroke of prior art is about 2 times of the present invention; Therefore, compared to existing technology, the present invention has higher radiating efficiency, and the fan power is simultaneously less, and radiation energy consumption is lower, and meanwhile, the working temperature being more conducive to reducing IGBT assembly is compared to existing technology lower.
As preferably of the present invention, this kind of great power conversion circuit plant capacity module group also comprises the module carrier be fixedly connected with radiator, and described IGBT assembly is fixed on radiator.
Above-mentioned setting, makes IGBT assembly, the weight of radiator is all born by module carrier; The weight of IGBT assembly is not born by stack bus bar, thus reduces the heavy burden of stack bus bar, in Long-Time Service, avoids the deformation of stack bus bar, thus improves the useful life of stack bus bar.
As preferably of the present invention, this kind of great power conversion circuit plant capacity module group also comprise be fixed on module carrier bottom and capacitance bracket for being fixedly connected with capacitance component.
Above-mentioned setting, is made the weight of capacitance component be married again on module carrier by capacitance bracket, instead of is born by stack bus bar, thus reduce the heavy burden of stack bus bar further, in Long-Time Service, avoid the deformation of stack bus bar further, thus improve the useful life of stack bus bar.
In sum, the present invention has following beneficial effect:
1, three power models independently arrange and concentrate on the longitudinal form arranged of one piece of stack bus bar, carrying of being more convenient for, assembling compared with three power models in prior art, are particularly convenient to maintenance and maintenance;
2, the power of the blower fan of heat radiation required for the present invention is lower, therefore, is conducive to the unsteady flow power improving power model group;
3, the power of the blower fan of heat radiation required for the present invention is lower, and therefore, the noise of blower fan is also less;
4, the present invention has good radiating effect, thus is conducive to the working temperature reducing IGBT assembly, and then is conducive to improving inversion efficiency;
5, compact conformation of the present invention, volume is little, is conducive to improving space availability ratio.
Summary of the invention
