Description

Wind electric converter electric capacity heat radiating type power cell
Technical field
The utility model relates to a kind of power cell structure for wind-force generating converter, specifically is a kind of wind electric converter electric capacity heat radiating type power cell.
Background technology
In wind electric converter, the power cell part all is the structure that is independent of cabinet, and cabinet internal heat generation device and power cell part all are to finish heat exchange by recirculated water, thereby reach the purpose of heat radiation.As the core of wind electric converter, the power cell design time generally all is only the IGBT module to be cooled off, and miscellaneous part such as electric capacity, busbar are because with respect to the little and consideration of not dispelling the heat of IGBT module caloric value.
And it is actual under wind field ruuning situation, on-the-spot service conditions is complicated and changeable add the windward tower and converter structure airtight, make that the heat of IGBT module can not be taken away fully, the power cell internal calorific power builds up, inner other devices of power cell such as stack bus bar, electric capacity also can generate heat simultaneously, when accumulation of heat will influence the performance that direct current supports electric capacity to a certain degree the time, even damage device.
Summary of the invention
Technical problem to be solved in the utility model is that the wind electric converter that a kind of heat-sinking capability is strong, dependability is good electric capacity heat radiating type power cell is provided.
Wind electric converter of the present utility model includes a housing with electric capacity heat radiating type power cell, two parts before and after the housing inner chamber is divided into by a dividing plate; Membrane front face is installed cooled plate, and the IGBT module is installed on the cooled plate; The dividing plate back side is equipped with the electric capacity busbar by insulator, and the direct current thin-film capacitor is installed on the electric capacity busbar, and the direct current thin-film capacitor outside is connected with the air-cooled radiator substrate.
Described air-cooled radiator substrate back is provided with parallel radiating fin, and air-cooled radiator substrate arranged outside cover plate forms heat dissipation wind channel between air-cooled radiator substrate and the cover plate, and radiating fin vertically is arranged in heat dissipation wind channel.
The utility model has increased air-cooled radiator and the heat dissipation wind channel that the direct current thin-film capacitor is strengthened dispelling the heat on conventional power cellular construction basis, and the heat-sinking capability of power cell is improved greatly, has guaranteed the reliable and stable operation of wind power equipment.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
As shown in the figure, wind electric converter of the present utility model includes a housing 1 with electric capacity heat radiating type power cell, two parts before and after the housing inner chamber is divided into by a dividing plate 2; Membrane front face is installed cooled plate 3, and IGBT module 4 is installed on the cooled plate; The dividing plate back side is equipped with electric capacity busbar 6 by insulator 5, and direct current thin-film capacitor 7 is installed on the electric capacity busbar, and the direct current thin-film capacitor outside is connected with air-cooled radiator substrate 8.Air-cooled radiator substrate 8 back sides arrange parallel radiating fin 9, and air-cooled radiator substrate 8 arranged outside cover plates 10 form heat dissipation wind channel 11 between air-cooled radiator substrate 8 and the cover plate 10, and radiating fin 9 vertically is arranged in heat dissipation wind channel.
