Heat exchangers utilizing flat surfaced passages to contact, contain and utilize fluidized small solid particles is provided. Top and bottom woven wire mesh or perforated sheet corrugated with rounded or flat-sided ridges are attached to respective top and bottom sides of said passage to increase its surface and to prevent said small solid particles from exiting said heat exchanger. A variety of shapes of the small solid particles are provided to further enhance the heat transfer rate. More energy efficient systems of all kinds will result from the use of these smaller heat exchangers.
