PROBLEM TO BE SOLVED: To provide a heat dissipation device for a solid insulation type switch unit capable of reducing thermal resistance in a connection part between a main circuit conductor and the heat dissipation device and improving workability of mounting.SOLUTION: The present invention relates to a heat dissipation device that is mounted in a bushing conductor of a solid insulation type switch unit. The heat dissipation device comprises: a heat dissipation member including a connection part in which a bolt penetration hole is opened, and consisting of a metal material; a housing including a head part into which the bushing conductor is inserted and an insulation plug insertion part into which an insulation plug is inserted, and consisting of a solid insulator; and a bolt which fastens the heat dissipation member and the bushing conductor. In the heat dissipation device for the solid insulation type switch unit, the insulation plug insertion part and the head part are connected, and the bolt is inserted from the side of the insulation plug insertion part and disposed while penetrating the bolt penetration hole in the connection part that protrudes into the head part.SELECTED DRAWING: Figure 3
