A plate heat exchanger has elements through which a medium flows. The elements are two thin metal plates, in at least one of which passages and opposed manifolds connecting the passages are formed by deep drawing. The plates are coated with a sealing adhesive and bonded together. The manifolds extend across the entire length of the elements and are closed at their ends by end closures inserted in the manifolds and sealed to the plates. Distributing conduits running transversely to the plates of the heat exchange elements, are connected to channels provided in the end closures so that the medium can flow from a distributing conduit through an end closure into a deeper shaped manifold and then into the passages and leave the elements in a corresponding manner. Pipes having a cross-shaped cross-section can be inserted in the end closures to serve as distributing conduits and also as tie-rods to hold the elements of the heat exchanger together. |
