ABSTRACT:
This invention relates to arrangement in heat exchangers, comprising a large number of heat exchange plates which, in compressed position, form throughflow passages for the heat exchange media, a first preferably stationary end wall situated on one side of the heat exchange plates and a second end wall situated on the opposite side of said plates and adapted to be displaced by clamping means towards said first end wall in order to sealingly compress the heat exchange plates, said preferably stationary end wall supporting a bar projecting therefrom and extending through recesses arranged in the heat exchange plates in order to locate said plates mutually and relative to the end walls against displacement in the plane of the plates when the clamping means are disconnected and/or the second end wall is removed, said bar having a length exceeding the distance between the end walls in the position where they compress the plates.
According to the invention the bar which is detachably fitted to the first end wall, has close to said wall a stationary abutment serving as an end stop for the plates in one direction and at its opposite end wall a means being withdrawable against spring action and serving as an end stop, said means being spaced from said first abutment exceeding the total thickness of the heat exchange plates.
