Provided is a stacked oil cooler comprising: a tube unit; an inflow flange; and an outflow flange, wherein the tube unit includes a top plate, a bottom plate, and a tube member which is arranged between the top plate and the bottom plate, forms a passage therein so that a first heat exchange medium flows through the passage, and performs heat exchange between the first heat exchange medium and an external second heat exchange medium. The tube member includes: at least one first tube member which includes a first plate and a second plate arranged on a lower side of the first plate and mutually molten and coupled with the first plate to form a passage; and a second tube member which is arranged on the bottom plate, has a structure same as that of the first plate, and has a third plate and a fourth plate mutually molten and coupled by vertically facing each other. Therefore, the stacked oil cooler can increase workability and productivity by simplifying types of components and improving assembling properties and increase reliability of a product by improving heat radiation and pressure resistance. |
