APPARATUS FOR RECOVERING HEAT ENERGY AND CONTACT-FREE ELECTRONIC CIGARETTE HEATER WITH AIR HEATING WITH SAID APPARATUS Russian patent published in 2023 - IPC A24F40/46 

FIELD: heating.

SUBSTANCE: group of inventions relates to an apparatus for recovering heat energy and a contact-free electronic cigarette heater with air heating with said apparatus. Apparatus for recovering heat energy includes a body of an aluminium oxide ceramic tube, forming an empty cavity configured to accommodate a heating element; a first cellular porous channel is located in the side wall of the body of the aluminium oxide ceramic tube, and the first cellular porous channel divides the body of the aluminium oxide ceramic tube into an outer wall and an inner wall. In the apparatus for recovering heat energy according to the invention, the side wall of the body of the aluminium oxide ceramic tube has a unique cellular porous structure; when the heating element placed in the formed empty cavity sinters the smoking product, the heat not acting on the smoking product is transferred to the body of the aluminium oxide ceramic tube.

EFFECT: since highly pure aluminium oxide ceramics with a relatively high heat conductivity coefficient are used for the body, part of the body of the aluminium oxide ceramic tube will be heated faster and further heat the air in the porous channel; when inhaling, the channel can recover heat and conserve energy.
