Abstract
A lockable, mechanically secure coupling is provided for heat exchanger tubes which are connected together by end plates into superimposed layers (A or B) to form hydraulic connections between the extremities of two tubes (1) using tubular elbows (3). Each tubular elbow (3) has a coupling member (5) connected to the extremities thereof by welding, brazing or glueing to form a coupling flange. The subassembly comprising an elbow with its coupling member (5) is received in a countersunk recess (10) in the external face of the end plate and is mechanically locked by pairs of straight pins (13) which extend into spaced parallel bores (12) or (15), disposed orthogonally to the axis (XX) of the tubes (1), each pin (13) being received in an external semicircular groove (9) of the coupling member (5). The invention provides a tight, mechanically sound joint for the hydraulic connections between tubular heat exchangers used in thermoelectric devices employed as heat pumps or as electrical generators.
