Abstract
A heat exchange device is disclosed herein to be used in conjunction with a standard fireplace. The heat exchange device is made from a continuous tube fabricated into loops that surround the burning fuel. The ambient room air, introduced through an opening for air entry into the tube, is blown through the internal lumen of the tube fabricated into loops, the external surfaces of which are in direct contact with burning fuel and flame. The air passing through the internal lumen of the tube fabricated into loops is heated to a high temperature by the burning fuel and flame.
Claims15
A forced-air heat-exchanger apparatus for a fireplace promoting heating of room air via placement substantially within a fireplace;
- said apparatus comprising:
- a) a continuous tube having at least two ends, an extralumenal surface covering the entire external surface of the tube, and an intralumenal surface covering the entire internal surface of the tube, the continuous tube substantially coiled in a form of approximate spirals or approximate polygons of several turns,
- b) an internal lumen or bore of the tube extending continuously from one of the two ends of said continuous tube to the other end of the continuous tube to accommodate movement and heating of said room air,
- c) an air-entry opening at one of the two end of said continuous tube for entry of the room air into said internal lumen or bore of the tube and the air-entry opening positioned substantially outside the fireplace,
- d) an air-exit opening at the other end of said continuous tube for discharge of heated room air out of said internal lumen into the room and the air-exit opening positioned substantially outside the fireplace, and
- e) an air-blower means attached to said air-entry opening or air-exit opening for forced movement of the room air into the air-entry opening, through the continuous internal lumen, and out the air-exit opening into the room.
A forced-air heat-exchanger apparatus for a fireplace promoting heating of room air via placement substantially within a fireplace;
- said apparatus comprising:
- a) a continuous tube having an open end and a closed end, the continuous tube substantially coiled in a form of approximate spirals or approximate polygons of several turns,
- b) two internal lumens separated by a wall within the tube extending substantially from the open end of the tube to the closed end of the continuous tube,
- c) one or more communicating aperture means between the two internal lumens, said aperture means placed adjacent to the closed end of the tube for flow of air from one of the two internal lumens to the other internal lumen,
- d) an air-entry opening at the open end of said continuous tube for entry of the room air into one of the two internal lumens of the tube and the air-entry opening positioned substantially outside the fireplace,
- e) an air-exit opening at the open end of said continuous tube for discharge of heated room air out of the second internal lumen into the room and the air-exit opening positioned substantially outside the fireplace, and
- f) an air-blower means attached to said air-entry opening or air-exit opening for facilitating movement of the room air into the air-entry opening, through one of the two internal lumen, through the communicating aperture means, through the second internal lumen, and out the air-exit opening into the room.
