Research on the isobaric evaporative cooling system of power thyristor

This paper discusses with the application field of power thyristor. Power thyristor will produce a great quantity of heat, and the standard of its rated current is temperature. With the increase of the current capacity, it demands more efficient cooling systems. Therefore, the study of cooling is a matter of great significance. Evaporative cooling is a high efficient and cleaning cooling method. In the airtight cooling system, the inner pressure increases with the increase of the heat load. When the environmental temperature is high, the inner pressure may be 0.3 MPa, and it is much dangerous. For this reason, an isobaric evaporative cooling system is put forward.
