摘要： Poor heat exchange in a heat exchanger between a flue gas passing through the heat exchanger and air being forced through the heat exchanger can be improved in a heat exchanger and combustor (30) for exchanging heat between a forced air stream and a flue gas generated by a plurality of spaced, parallel burners (44) with a construction including spaced, upper and lower headers (32, 34), a plurality of tubes (50), one for each burner (44) extending in parallel between and mounted to the headers (32, 34). Each tube (50) has a first section (56) of enlarged cross section adapted to serve as a combustor for fuel to generate the flue gas and a narrowed, second section (70) for exchanging heat between the flue gas and the forced air stream. Each second section includes generally flat, parallel spaced walls (58, 60) with each of the walls (58, 60) having dimples (74) therein which are directed toward the other of the walls (58. 60) into substantially contacting or almost contacting relationship therewith.

摘要： The heat exchange assembly for unit heaters and like apparatus for the treatment of hot air is of the type comprising a heat exchanger formed of flues and air tubes and a combustion chamber. The inventive caracteristics thereof are the following:

the flues (17) have, in cross-section, the shape of a trapezoid with the small base placed at the bottom;
the air tubes (15) are arranged side by side in such a manner as to form therebetween a flue (17);
the lower portion (19) of the air tubes forms the roof of the combustion chamber (9);
the flues (17) have in cross-section the shape of a trapezoid with the small base placed at the top;
the side walls (21) of the air tubes (15) are provided with impressions (18) for avoiding a laminar flow of the flue gas and imparting thereto the necessary turbulence.

摘要： A hot-air furnace has a long-flame burner (12) for combusting gas or liquid fuel with a combustion chamber (13) connected to the burner (12) and having its length ( l ) and width (w₁) in relationship of w₁ l . A heat exchanger (15) is located above the combustion chamber (13) and has internally a gas flow guide plate (14) which guides combustion gas flow (31) discharged from the combustion chamber (13) to the heat exchanger (15). The heat exchanger (15) has a width (w₂) and length ( l ) in the relationship of w₂ l . An exhaust port (16) for exhausting the combustion gas flow (31) is located at the front or rear of, right or left-hand side of or on the top side above said heat exchanger (15). A casing (10) has a drum (11) integrally connecting the combustion chamber (13) and the heat exchanger (15), an air flow guide and directing plate (23) which covers the drum (11), a radiant heat absorber plate (22) outside the combustion chamber (13), and a blower (19) above or below the drum (11). A discharge port (20) is mounted in such a manner that the direction of discharging air flow (32) corresponds to the up or down position of the blower (19).
