FIELD: heat engineering.
SUBSTANCE: invention can be used in heating devices. In a heating device with convection chambers, including a coil with convection plates installed on it, while the convection plates have grooves in the shape of the coil, the first convection plates tightly cover the surface areas of the coil and, due to their shape, form the central convection chambers, the subsequent convection plates tightly cover sections of the surface of the first plates and, due to their shape, form side convection chambers; inlet and outlet channels for air are provided in the convection chambers.
EFFECT: increase in the manufacturability of the assembly and the efficiency of convective heat transfer.
