<P>PROBLEM TO BE SOLVED: To provide a structure which improves the cooling performance of a heat transmission member while enabling a coolant pipeline to be securely disposed on a groove of the heat transmission member. <P>SOLUTION: A coolant cooling mechanism includes: a coolant pipeline (15) having first and second straight tube parts (16a, 16b) which are arranged parallel to each other and a curved tube part (17) connecting end parts of the first and second straight tube parts (16a, 16b) with each other; a heat transmission member (70) having a heat transmission part (70b) thermally connecting with a cooled component (63), a first groove part (72a) having an opening width into which the first straight tube part (16a) fits, and a second groove part (72b) having an opening width larger than an outer diameter of the second straight tube part (16b); and a pressing mechanism (65) respectively pressing the first straight tube part (16a) and the second straight tube part (16b) to the first groove part (72a) side and the second groove part (72b) side. <P>COPYRIGHT: (C)2013,JPO&INPIT |
