The invention relates to a photo-thyristor valve body radiating with heat pipe, which comprises a thyristor unit, an optical groove unit, an adsorption capacity unit, a damping resistance unit, a feedback unit and a framework unit and is characterized in that the thyristor unit and the damping resistance unit both use the mode of the self-cooling heating dissipation; the thyristor unit comprises a plurality of photo-thyristor elements and a heat pipe radiator comprising a heat pipe, a cooling plate, and a basal plate; the photo-thyristor elements adopt the mode of the self-cooling heating dissipation of the heat pipe radiating; a heat emitting element of the damping resistance unit is an entity section material radiator. The photo-thyristor valve body has the advantages of simple structure, convenient installation, noiselessness, non-maintaining, the valve bank occupying smaller floor area, etc.
