Heat exchanger baffle assembly with horizontal gap

A heating, ventilation, and/or air conditioning (HVAC) system comprising:

• an evaporator coil;
• a furnace in airflow communication with the evaporator coil, the furnace comprising:
• a furnace heat exchanger;
• a baffle assembly disposed adjacent to the furnace heat exchanger, the baffle assembly comprising at least one horizontal gap;
• and
• a fan in airflow communication with the furnace heat exchanger and the evaporator coil,
• wherein the baffle assembly comprises a first side and a second side, and further wherein the first side or both the first side and the second side comprise a first section and a second section, the at least one horizontal gap disposed between the first section and the second section,
• wherein the first section of the first side comprises a first leg and a second leg, a first angle defined between the first leg and the second leg having a value between 130° and 160°,
• wherein the second section of the first side consists essentially of a first leg, wherein the first leg of the second section of the first side comprises an end which is free,
• wherein the first leg of the first section of the first side and the first leg of the second section of the first side are approximately planar, and
• wherein the second section of the second side comprises a first leg, and the first section of the second side and the first leg of the second section of the second side are approximately parallel.
