This disclosure is directed to a liquid cooling device, and in particular to a liquid cooling device capable of contacting a heat source through multiple directions.


Description of Related Art

The related-art batteries for an electric vehicle are electrically connected by a conductive copper bar, and a large amount of heat is accumulated at the conductive copper bar when the battery is discharged. A related-art method for heat dissipation is installing a water-cooling plate on the conductive copper busbar to remove the heat so as to maintain the copper bar at a normal operating temperature. According to the related-art art, two metal sheets or forgings disposed upper and lower are brazed with each other to form the water-cooling plate having a closed chamber therein. A fluid is circulated through a flow path defined in the closed chamber so that heat generated by the copper bar is removed by the fluid. However, the related-art water-cooling plate should be disposed parallelly to the conductive copper bar, and therefore the arrangements are limited.


In view of the above drawbacks, the inventor proposes this disclosure based on his expert knowledge and elaborate researches in order to solve the problems of related art.
