Abstract (en)
[origin: EP0826941A2] The heat exchanger has a pipe block that comprises a number of pipes (1) which are arranged next to each other with intermediate spacings. The pipes are flat at their end areas and between those ends, rigidly held spacers (5,5a-b) are provided with a connecting channel along each cross side of the pipe block. The pipes are sealed at their ends and have a cross aperture which is connected to cross apertures of the spacers. In the space (2) formed between two adjacent pipes a pair of partition spacers (5a-b) is held and these spacers are not apertured, thus partitioning the connecting channel into two parts and separating the flow so as to form pipe block sections where more than one fluid mediums can flow.
