Abstract
A heat exchanger of annular cross-section and having outer and inner concentric walls has arranged within its annular space a plurality of tubes each of the same involute form. The tubes may be arranged in layers within the space and in one embodiment a fluidized bed of particulate material can be supported within the space with the tubes immersed within the bed. The tubes constitute a fluid path through the space for heat exchange as a fluid, in use, passes therethrough.
