Claims

[Scope of utility model registration request]

A plurality of heat exchange units each having a fin sandwiched between a pair of mail plates joined in a liquid-tight structure are stacked, and oil introduced from an introduction opening formed in each mail plate passes through the fins. In the oil cooler, the cooled oil is cooled by exchanging heat with the mail plate and is discharged from a discharge opening formed in the mail plate, at least one heat exchanger located at the outermost side of the plurality of heat exchange units. A thick veneer reinforcing plate is fixed between the pair of single mail plates to surround the entire circumference of the introduction opening, the ejection opening, or both of these openings, and the reinforcing plate is provided with the opening and the fins. An oil cooler characterized by forming a plurality of narrow grooves that communicate with each other.
