Block-in-shell heat exchanger

Abstract

A block in shell type heat exchanger having a jacket surrounding a jacket space to receive first medium. The jacket space accommodates a plate and block heat exchanger with first and second heat exchange passages. A first collector and a second collector connect to the second heat exchange passages for introduction and withdrawal of the second medium. A pipe extends from the second collector and exits the jacket space through an opening in the jacket to withdraw the second medium. The first collector has an inlet stub situated perpendicular to the extension of the first collector. The second medium can be introduced through the inlet stub into the first collector. A third collector is arranged in the jacket space and connects with the inlet stub and has the form of a hollow sphere or a hollow half-sphere.
