Abstract
A heat exchanger comprises a housing containing upper and lower layers of fluid, the upper layer being less dense than the lower layer. The large and sharp density gradient at the interface between the upper and lower layer acts to prevent mixing of the two layers. A plurality of vertically oriented tubular sleeves that are closed at each end and filled with fresh water are located in the housing such that the axial ends of each tubular sleeve are in different ones of the layers. Heat added to the liquid in the lower layer is transferred to the liquid in the upper layer through the medium of the water container in the tubular sleeves.
