A heat exchanger is disclosed comprising a plurality of spaced apart parallel plates having a plurality of apertures therein, a plurality of hollow frusto-conically shaped cone members having a larger base end and a smaller opposite end with the cone members being inserted in the apertures of the plate and being of such relative size to be tightly embraced by the peripheries of the apertures, the opposite ends of the cones in each of the plates being tightly nested and stacked in the base ends of the cones in the next adjacent plate, and means for fixedly securing the plates in parallel relation to bind the cone members in stacked relation.
