Abstract
In a plate heat exchanger (1) comprising a package (3) of heat transfer plates (2) arranged between two frame plates at least one of the frame plates (6) is provided with connection pipes (9) for one or two heat exchange fluids. The connection pipes (9) are provided with internal linings (10), which are permanently connected round the ports (4) to an outer heat transfer plate (14) of the package (3) of heat transfer plates (2). Each lining (10) is arranged with room (12) for radial movement inside its connection pipe (9) and provided with at least one bellows (11) adapted--upon relative displacement between the one frame plate (6) and the outer heat transfer plate (14) in a direction across the connection pipe (9)--to facilitate bending of the lining (10). Thereby, a very compact plate heat exchanger (1) can be obtained.
