LIQUID-COOLED-TYPE COOLING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a liquid-cooled-type cooling device capable of securely preventing positional shift of a fin when the cooling device is manufactured.

SOLUTION: The liquid-cooled-type cooling device 1 includes a casing 2 which has a cooling-liquid inlet 11 formed at a rear end portion and a cooling-liquid outlet 12 formed at a front end portion. The fin 17 for forming a plurality of flow channels 18 is disposed within the casing 2 to be located between the cooling-liquid inlet 11 and the cooling-liquid outlet 12. A portion of the interior of the casing 2 located rearward of the fin 17 serves as an inlet header section 21, and a portion of the interior of the casing located frontward of the fin 17 serves as an outlet header section 22. A rear side surface within the inlet header section 21 is skewed toward the fin 17 in a direction from the right side toward the left side. A positioning vertical surface 23 extending straight along the left-right direction and positioning the rear end portion of the fin 17 is provided to the lower portion of a left end portion of the rear side surface within the inlet header section 21. The rear end portion of the fin is brought into contact with the positioning vertical surface 23.
