<p>An oil cooler is provided to improve cooling efficiency by narrowing a cross section of a cooling flow path. An oil inlet port(120) is formed in one side of an external pipe(110). An oil outlet port(130) is formed in a position adjacent to the oil inlet port. An internal pipe(115) is inserted inside the external pipe. A plurality of cooling pins is positioned in an oil moving path which is a space between the external pipe and the internal pipe. A partition(140) forms a first oil moving path(117) and a second oil moving path(118). An oil communicating path(145) is formed in the other end part of the partition.</p> |
