Abstract
A high-power thyristor module includes a housing configured with an inner receiving space, and a thyristor unit disposed in the inner receiving space in the housing and including a mounting frame, and a plurality of high-power thyristors mounted on the mounting frame. Each thyristor has a gate. The mounting frame includes a dielectric top plate disposed on a top side of the housing, and a plurality of electrodes mounted on the top plate so that the electrodes are exposed outwardly of the housing, and coupled respectively to the gates of the thyristors. Cooling oil is contained in the inner receiving space so that the thyristors are submerged thereby.
Claims19
A high-power thyristor module comprising:
- a housing configured with an inner receiving space;
- a thyristor unit disposed in said inner receiving space in said housing, said thyristor unit including a mounting frame, and a plurality of high-power thyristors mounted on said mounting frame, each of said thyristors having a gate, said mounting frame including a dielectric top plate disposed on a top side of said housing, and a plurality of electrodes mounted on said top plate so that said electrodes are exposed outwardly of said housing, and coupled respectively to said gates of said thyristors;
- cooling oil contained in said inner receiving space so that said thyristors are submerged thereby;
- wherein said mounting frame of said thyristor unit further includes a dielectric bottom plate disposed under said top plate and spaced apart from said thyristors;
- and
- wherein said thyristor unit further includes a plurality of heat sink units each disposed fixedly on said bottom plate for dissipating heat generated by a corresponding one of said thyristors.
A high-power thyristor module comprising:
- a housing configured with an inner receiving space;
- a thyristor unit disposed in said inner receiving space in said housing, said thyristor unit including a mounting frame, and a plurality of high-power thyristors mounted on said mounting frame, each of said thyristors having a gate, said mounting frame including a dielectric top plate disposed on a top side of said housing, and a plurality of electrodes mounted on said top plate so that said electrodes are exposed outwardly of said housing, and coupled respectively to said gates of said thyristors;
- cooling oil contained in said inner receiving space so that said thyristors are submerged thereby;
- and
- a pipe disposed in said inner receiving space in said housing and having a first end extending through said housing and disposed adjacent to said top side of said housing, and a second end opposite to said first end, extending through said housing and disposed adjacent to a bottom side of said housing, said pipe being adapted to permit a heat exchanging coolant from an external coolant source to flow thereinto through said first end and to flow out of said pipe through said second end;
- wherein said pipe is helical and is attached to a looped inner surrounding surface of said housing.
