Abstract
The utility model provides a high-efficiency heat exchange warm air furnace. Combustion flue gas of a combustion chamber in the furnace body flows through a longitudinal flue gas tube bundle, a smoke collecting box which is communicated with the upper end of the flue gas tube bundle, an upper transverse flue gas tube bundle and a chimney rising channel. The flue gas tube bundles which are bidirectionally arranged longitudinally and transversely effectively prolong travel distance of the combustion flue gas in the furnace and enlarge a heat exchange surface. Particularly the cold air is introduced to and flushes a combustion chamber part with concentrated and sufficient heat. The high-efficiency heat exchange warm air furnace has the following advantages: sufficient heat absorption of cold air, improved heat exchange rate, remarkably prolonged service life, small overall volume and reduced space occupation.
