| 摘要 |
The invention relates to a cooling jacket (100) for cooling a heat-generating element (300) through transmitting heat generated therein into a liquid coolant flowing inside thereof, which is mounted within an electronic apparatus; it comprises a base portion (110), having a heat-transfer surface (111) to be in contact with a surface of the heat-generating element (300), and a plural number of wall portions (113), each being defined to extend into a direction perpendicular to the heat-transfer surface (111), thereby defining flow passages (114) for the liquid coolant between the wall portions (113), and a cover portion (120), being attached to the base portion (110) surrounding the periphery thereof, thereby defining a flow passage (114) for guiding the liquid coolant into the base portion (110), wherein the base portion (110) builds up sector-like shaped flow passages (114) and a summit portion (112) at the central portion of the base portion (110), and has a configuration being thermally isotropic to the heat-generating element (300) to be in contact therewith. |
