ABSTRACT:
A cooler for engine lubricant oil is formed by a stack of heat exchanger modules each defining therein a first space for engine cooling water. A second space is defined between each adjacent pair of modules. The first spaces in respective modules are communicated with each other by water inlets and outlets. The second spaces are communicated with each other by openings. One of the outermost modules is sealingly connected to a part of a lubricant circuit of the engine while the other outermost module is sealingly connected with an oil filter so that hot lubricant oil from the engine flows through the second spaces in the stack of modules into the oil filter in heat exchange relationship with engine cooling water flowing through the first spaces in respective modules. The oil filter is communicated with another part of lubricant circuit for the recirculation of cleaned oil back into the engine.
