Abstract

Ein Rohrwärmetauscher weist wenigstens zwei konzentrisch ineinander angeordnete Rohre (1, 2, 3, 4) auf, wobei zwischen diesen Rohren (1, 2, 3, 4) wenigstens ein schraubenförmiger Kanal (5, 6, 7) angeordnet ist, welcher von der Außenwand (9) des inneren Rohres (2, 3, 4) und der Innenwand (8) des äußeren Rohres (1, 2, 3) begrenzt wird. Der Kanal (5, 6, 7) wird weiters von einem Draht (12) begrenzt, der schraubenförmig zwischen den beiden Rohren (1, 2, 3, 4) angeordnet und zwischen diesen beiden Rohren (1, 2, 3, 4) festgeklemmt ist. Durch dieses Klemmen wird automatisch die erforderliche Dichtigkeit geschaffen, wobei das Klemmen auf einfache Weise durch das Verschieben der beiden Rohre gegeneinander bewirkt werden kann.

A tube heat exchanger has at least two tubes (1, 2, 3, 4) arranged concentrically with one another, wherein between these tubes (1, 2, 3, 4) at least one helical channel (5, 6, 7) is arranged, which differs from the one Outer wall (9) of the inner tube (2, 3, 4) and the inner wall (8) of the outer tube (1, 2, 3) is limited. The channel (5, 6, 7) is further bounded by a wire (12) arranged helically between the two tubes (1, 2, 3, 4) and clamped between these two tubes (1, 2, 3, 4) is. By this clamping the required tightness is automatically created, the terminals can be effected in a simple manner by moving the two tubes against each other.
