Abstract
An oil cooler includes a heat exchanging core 40 which includes a stack of heat exchanging plates 40. Each of the heat exchanging plates 40 includes a first set of openings 61 and 62 and a second set of openings 65, 66 and 67. The openings 65, 66 and 67 in the second set construct rows which are spaced along the width W of the plates 40. The openings between the first and second sets are alternately arranged along a direction of the width W of the plates. The openings 61 and 62 in the first set are symmetrical about a central axis X--X, while the openings 65, 66 or 67 in each row are asymmetric about the axis X--X. The stack of the plates 40 is such that the plates are alternately reversed, so that the symmetrical openings 61 and 62 are in communication with each other in the stack to created a first passageways 63 and 64 in the direction transverse to the plane of the plates 40 for the water, and so that the asymmetrical openings 65, 66 and 67 are in communication with each other in the stack to created a second passageways 68, 69 and 70 in the direction parallel to the plane of the plates. The plates 40 are provided with partitions 220 and 222 for dividing the second passageways into the groups 68, 69 and 70 for different oils.
