Abstract

A frame plate (11) for a plate heat exchanger has two ports (12, 13), to which there are connected two tubes provided with annular flanges (16, 17). The ports (12, 13) are situated so close to each other that there is no room for the flanges (16, 17) of the two tubes to be arranged side by side. The problem is solved, according to the invention, by arranging at least one port (12), between the frame plate (11) and the annular tube flange (16), at least one removable spacing member (14) surrounding a communication channel between the port (12) and the interior of the tube, the tube flange (16), further, being connected with the frame plate (11) by means (18) separate from the spacing member (14) in a manner such that the latter is clamped between the frame plate (11) and the tube flange (16).
