PURPOSE:To prevent water leakage due to the dissolution of a hose nipple and a short-circuit accident resulting from the water leakage by electrically insulating a conductive section and a water flow section in a water-cooled fin for a semiconductor element by an insulating tube. CONSTITUTION:Water-cooled fins 2, 3 consists of insulating tubes 15 as water flow sections for the fins 2, 3 and water-cooled blocks 16 as conductive sections for the fins 2, 3. The insulating tubes 15 and the blocks 16 are joined by adhesives having excellent thermal conductivity. Consequently, DC voltage is applied between the fins 2, 3 by a semiconductor element 1, but potential difference is not generated between the fins 2, 3. Accordingly, the leakage of water due to the dissolution of hose nipples 4, 5 and a short-circuit accident resulting from said leakage are prevented. |
