Abstract
An evaporator comprises a plurality of plate assemblies, each consisting of four plates put together with a predetermined distance defined between adjacent plates. In each plate assembly, between the two opposed inner plates, a space into which a liquid to be evaporated is introduced is defined by gaskets extending between and around the outer peripheries of the inner plates. Further, the inner plates and the two outer plates disposed outside the inner plates cooperate with gaskets extending between and around the outer peripheries of the plates to define two evaporating spaces therebetween which are disposed on opposite sides of the central liquid introducing space. The inner plates are each formed with a number of apertures establishing communication between the introducing space and evaporating spaces. Further, the outer plates in each plate assembly cooperate with the outer plates in adjacent plate assemblies to define heat transmitting spaces into which a heating medium is introduced.
