AIR GUIDE STRUCTURE OF GAS HEATER

摘要

PURPOSE: Air guide structure of a gas heater is provided to improve the heat exchange efficiency of a gas heater and to prevent the loss of heat through a case by making the exterior air concentrically flow toward a heat exchanger. CONSTITUTION: A case includes a part chamber, a hot air flow path and an exterior air suction chamber defined by vertical and horizontal dividing plates. A gas heater includes a burner in the part chamber, a guide fan, first and second heat exchanger in the hot air flow path, and a convection fan in the exterior air suction chamber. An exterior guide structure(30) is placed in the hot air flow path.
