Abstract
A heat exchanger for the exchange of heat between two media (Ma, Mb), each of which flows through a respective one of two chambers (A, B) mutually separated by a medium-impervious partition wall (5) made of thermal conductive material. The interior of each of the flow chambers, or at least of one flow chamber, is divided into a large number of medium-flow passages, which are connected in parallel with respect to the flow of medium passing therethrough. The flow passages (13, and 17) have a substantially rectangular cross-section having a flow area which is so adapted in respect of the medium flowing therethrough that the flow in the passages is substantially laminar throughout the whole length of the passages, without a central turbulent zone. The passage walls defining the flow passages comprise a highly thermal-conductive material and are formed integrally with, or in good heat-conducting contact with the partition wall (5) located between the two flow chambers (A, B). The width (s) of the flow passages parallel with the partition wall is at most 1.5 mm and preferably less than 1.00 mm. The height (h) of the flow passages, and therewith the passage walls, at right angles to the p…
