Abstract:
1. A heat exchanger comprising: a main heat exchange housing in a rectangular form, a first side of the main heat exchange housing being at least partially integral with a connection mast; a cooling air inlet line and a hot air inlet line, wherein the hot air inlet line extends perpendicularly through the cooling air inlet line to form a heat pre-exchanger upstream of the main heat exchange housing, and wherein the hot air inlet line extends through a pyramid portion of the connection mast upstream of the heat pre-exchanger; a heat pre-exchanger cooling air outlet line extending to a cooling air inlet of the main heat exchange housing, the cooling air inlet of the main heat exchange housing positioned on the first side of the main heat exchange housing; and a heat pre-exchanger hot air outlet line extending to a hot air inlet of the main heat exchange housing, the hot air inlet of the main heat exchange housing positioned on a second side of the main heat exchange housing perpendicular to the first side such that hot airflow from the hot air inlet of the main heat exchange housing and cooling airflow from the cooling air inlet of the main heat exchange housing cross at approximately a right angle within the main heat exchange housing.
