ABSTRACT:
A heat exchanger has a heat-exchange plate having an edge and formed with a lurality of parallel spaced-apart longitudinal passages opening at the edge and with a plurality of transversely throughgoing plate holes at the edge between the passages. A manifold pipe formed with a row of manifold holes all opening in the same direction and spaced apart the same as the passages at the edge can be fitted to the plate with the plate edge over the row of manifold holes so that each of the passages is aligned longitudinally with a respective one of the manifold holes. A pair of L-section guides fixed on the pipe flank the row of manifold holes and define a gap corresponding to the shape of the plate at the edge. These guides are formed between the manifold holes with laterally throughgoing guide holes transversely alignable with the plate holes when the edge is fitted over the row of manifold holes. A plurality of holders can be engaged transversely through the aligned guide and plate holes for securing the plate to the manifold pipe for fluid flow between the passages and the interior of the pipe. A row of O-ring seals overlies the row of manifold holes to form tight joints where each manifold hole joins a plate hole.
