Einrichtung zur Kühlung einer druckkontaktierten Thyristor-Scheibenzelle

摘要

A cooling arrangement for dissipating the heat produced by a power thyristor disc includes a pair of metallic press blocks having a good heat conduction characteristic and which have their end faces clamped into pressure contact with opposite faces of the disc. Heat pipes filled with a vaporizable liquid are secured at the sides of the press blocks and these function to effect transfer of the heat from the blocks to the liquid causing it to vaporize and travel longitudinally in the direction away from the blocks. The heat in the vaporized liquid is removed by condensation on the pipe wall and transferred to the surrounding atmosphere by cooling fins located on the outer wall surface of the pipes. The condensate is then returned to the heating zones at the ends of the pipes for recycling by means of a metallic capillary structure lining the inner wall surface of the pipes.
