TRIANGULAR SHAPED HEAT EXCHANGER

摘要

A more efficient heat exchanger [10] with walls [12] of heat exchanger coils [14] oriented at compound angles [Angles A and B] with respect to its associated heat exchanger fan [18]. The bottom edge [20] of each heat exchanger coil wall [12] is oriented at an angle [Angle A] of between approximately 35 and 85 degrees to the fan [18], and each heat exchanger coil [14] is tilted inward at an angle [Angle B] of between approximately 35 and 85 degrees relative to a plane [22] connecting the two bottom edges [20] of the heat exchanger coil wall [12]. One or multiple coils [14] can be provided in each heat exchanger coil wall [12] and an optional top heat exchanger coil [14T] can be added to the top [24] of the heat exchanger [10]. The front [30] of the heat exchanger [10], which is normally pointed for forced draft units, is replaced with a triangular shaped plate [38] and a modified trapezoidal shaped base [22"] for induced draft units [10"].
