Abstract
An evaporator has main passages placed in a heat-exchange relationship, an arrangement for forming a pool of the liquid to be evaporated so that it flows through at least a first of the main passages, and a device for introducing a refrigerant into at least a second of the main passages so that evaporation of the liquid is ensured. The or each first main passage possesses, in the free section transverse to the direction of flow of the liquid to be evaporated, at least one continuous free-flow region sufficiently extended to allow the liquid to get round a deposit of impurities, or, the main passages being bounded by vertical plates having a substantially similar contour and being parallel and spaced apart so as to form the flat main passages, at least one first main passage is either narrower than the corrugation nor an auxiliary passage, or contains one or more closed auxiliary passages which extend over most of the length of the heat exchanger body parallel to the direction of flow of the liquid to be evaporated, the walls of the auxiliary passage(s) touching the plates defining the main passage.
