The invention relates to a power unit structure for a wind power converter, and particularly relates to a capacitive heat-dissipation power unit for a wind power converter. The capacitive heat-dissipation power unit comprises a shell; an inner cavity of the shell is divided into a front part and a rear part through a partition board; a water cooling board is mounted on the front face of the partition board; an IGBT (Insulated Gate Bipolar Translator) module is mounted on the water cooling board; a capacitive bus bar is mounted on the back face of the partition board through insulators; direct-current thin film capacitors are mounted on the capacitive bus bar; and air-cooling radiator substrates are connected with the outer sides of the direct-current thin film capacitors. The power unit structure provided by the invention is additionally provided with air cooling radiators and cooling air ducts for enhancing a cooling effect on the direct-current thin film capacitors on the basis of the conventional power unit, so that the heat dissipation capability of the power unit is greatly improved, and the stable and reliable operation of the wind power equipment can be ensured.
Description
Technical field
The present invention relates to a kind of power cell structure for wind-force generating converter, specifically 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, power cell when design 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 heating amount.
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, so 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 affect the performance of DC support electric capacity to a certain degree the time, even damage device.
Summary of the invention
Technical problem to be solved by this invention 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 invention includes a housing with electric capacity heat radiating type power cell, and the housing inner chamber is front and back two parts by a baffle for separating; 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 capacitor bus-bar by insulator, and the direct current thin-film capacitor is installed on the capacitor bus-bar, 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 present invention 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.
