Abstract
Stacked forced refrigeration thyristor air channels relate to a thyristor heat radiation system. According to the stacked forced refrigeration thyristor air channels, included are a thyristor group formed by connected thyristors, heat radiating plates fixedly connected with the thyristors, and air-flow channels. The upper and lower bottom surfaces of the air-flow channels are respectively provided with openings communicated with the outside and the peripheries of the air-flow channels are sealed. At least two fans used for promoting the circulation of air flows are arranged above the air-flow channels. The thyristor group and the heat radiating plates are arranged inside the air-flow channels. The heat radiating plates are mounted around the thyristors. Heat radiating fins are arranged on the heat radiating plates. The root portions of the heat radiating fins are connected with the heat radiating plates. The stacked forced refrigeration thyristor air channels employ a multi-fan type design instead of a traditional single-fan type design; the air channels of the thyristors are increased; and the heat radiating efficiency is effectively improved.
