Abstract (en)

[origin: EP0437825A2] Provided in a heat exchanger for the purpose of connecting the tubes (2) to the tube plate (1) are separate connecting elements (3) whose sleeve connections (7) engage friction-tight in the widened end of the tube (2), and whose flanges (5) are connected to the tube plate (1) in a liquid-tight and gas-tight fashion. <??>As a result, the production of the individual parts is rendered more favourable, as is also the assembly, the properties of the tube connections are improved, and it is possible to use arbitrary tube shapes and material combinations. <IMAGE>
