WATER-COOLED COOLER, CAPABLE OF IMPROVING COOLING EFFICIENCY BY IMPROVING A COOLANT PASSAGE, AND AN INVERTER THEREOF

摘要

PURPOSE: A water-cooled cooler and an inverter thereof are provided to uniformly distribute a coolant by forming a guide pin in the folded region of a coolant passage.;CONSTITUTION: A coolant passage(121) is formed in one side of a water-cooled cooler(120). The coolant passage includes an entrance, an exit, a first, and a third passage part. The first passage part is linearly extended from the entrance. The second passage part is curvedly extended from the first passage part. The third passage part is linearly extended from the second passage part in order to be connected to the exit. A guide pin(123) divides the second passage part into a plurality of passages. At least one cooling pin(124) is formed in the third passage part.;COPYRIGHT KIPO 2011
