Abstract

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

Claims

1. A triangular shaped heat exchanger comprising:

two heat exchanger coil walls attached to a heat exchanger fan at double and non-perpendicular angles with respect to the heat exchanger fan, each heat exchanger coil wall provided with at least one heat exchanger coil,

a triangular top attached to the fan and to top edges of the two heat exchanger coil walls,

a base attached to the fan and to bottom edges of the two heat exchanger coil walls so as to cooperate with the top and walls to form an internal plenum area of a triangular shaped heat exchanger,

each heat exchanger coil wall oriented at an angle of between approximately 35 and 85 degrees to the fan, and each heat exchanger coil wall tilted inward toward its associated heat exchanger coil wall at an angle of between approximately 35 and 85 degrees relative to the base,

each heat exchanger coil wall modified by shortening it so that each modified wall attaches by its front edge to a triangular shaped front plate, and

the base being modified to be trapezoidal shaped, and the triangular shaped front plate securing to the front edge of the modified trapezoidal shaped base.

2. A triangular shaped heat exchanger comprising:

two heat exchanger coil walls attached to a heat exchanger fan at double and non-perpendicular angles with respect to the heat exchanger fan, each heat exchanger coil wall provided with at least one heat exchanger coil,

a triangular top attached to the fan and to top edges of the two heat exchanger coil walls,

a base attached to the fan and to bottom edges of the two heat exchanger coil walls so as to cooperate with the top and walls to form an internal plenum area of a triangular shaped heat exchanger,

each heat exchanger coil wall modified by shortening it so that each modified wall attaches by its front edge to a triangular shaped front plate, and

the base being modified to be trapezoidal shaped, and the triangular shaped front plate securing to the front edge of the modified trapezoidal shaped base.
