Patent DE-4333904-A1 (DE)
Title: Channel heat exchanger
Inventor: PAUL EBERHARD DIPL ING
IPC: F28D9/00
Filed: 1993-09-27
Abstract: The channel heat exchanger consists of an s-shaped continuous profiled strip which is superimposed upon itself and has an excessive trapezoidal profile. The plates are supported among one another on the profile edges. Parallel flow channels (ducts) are produced which do not require to be sealed from one another. The channel heat exchanger is distinguished by two-dimensional heat transport, double the heat exchanging area by contrast with plate heat exchangers, improved passage of heat and less use of material by contrast with finned heat exchangers. The spiral flow generated by the structuring effects a further improvement in heat exchange. The heat exchange packet can be pushed like a cassette into a pressure-resistant (pressure-proof) housing and reextracted without dismantling the connecting pipelines. The heat exchanger can be implemented in a design without seals or without any jointed connection. Because of the smooth channels, no risk of contamination occurs. Nevertheless, mechanical and hydraulic cleaning is possible during operation. It is likewise possible during operation for the flow guidance, rate of flow, heat exchanging area and thus the heat transfer to be varied. The heat exchanger can be combined in a modular fashion and can, inter alia, be used for the purpose of utilizing waste heat (winter) and space cooling (summer) by indirect evaporative cooling in conjunction with a high efficiency.
