    Abstract: An apparatus includes a lubricating oil tank storing a lubricating oil. An oil separator separates the lubricating oil from a working fluid discharged from an expander of a waste heat recovery system. A lubricating oil return conduit is connected between the oil separator and the lubricating oil tank. A working fluid return conduit is connected between the lubricating oil tank and the oil separator. A vaporizer unit is installed in the lubricating oil tank to vaporize a liquefied working fluid mixed with the separated lubricating oil in the lubricating oil tank.

    Abstract: A heat exchanger for a vehicle includes: a housing having an interior space; a header installed at one end of the housing and having a first fluid inlet manifold; a second fluid inlet manifold; and a second fluid outlet manifold; and a heat exchange core installed in the interior of the housing and having a plurality of core elements spaced apart from each other. The plurality of core elements are coupled to the header, and a plurality of first fluid passage, through which the first fluid passes, is respectively formed between the adjacent core elements. Each of the core elements has a second fluid passage, through which the second fluid flows, an inlet of the second fluid passage communicates with the second fluid inlet manifold, and an outlet of the second fluid passage communicates with the second fluid outlet manifold.
