ABSTRACT:
This disclosure is directed to a heat exchanger which includes a coil through which a heat exchange medium, such as Freon, is circulated between an inlet and an outlet, the coil defining an interior chamber having a lower chamber portion, means for generating a flame, such as a natural gas burner at a lower end portion of the coil whereby heat is introduced into the interior chamber and rises upwardly therein such that the same might be absorbed by the heat exchange medium for subsequent utilization, a pair of baffle plates disposed within the interior chamber in generally upwardly opening diverging relationship for directing heat generally outwardly toward the coil for substantially total absorption thereof by the heat exchanger medium, and a fan for drawing a limited amount of air from the exterior of the coil to create a negative pressure for assuring air flow from the interior chamber to the exterior thereof through the coil.
