  • Air heater with angled PTC heaters producing diverging heated airflow
    Patent number: 5513296
    Abstract: A positive temperature coefficient (PTC) heater includes a housing, a fan mounted within the housing, a pair of positive temperature coefficient (PTC) heater assemblies disposed in the housing, and a plenum mounted in the housing. The housing includes a front portion and a rear portion connected together to define a front, a rear, a left side and a right side, the front and rear each having at least one opening. The fan is arranged to produce a flow of air from the rear of the housing to the front. The pair of positive temperature coefficient (PTC) heater assemblies are disposed in side by side relationship and angled relative to each other, each at an angle of approximately 7.5 degrees from normal, so as to produce a diverging column of heated air. The plenum mounted in the housing directs the air flow produced by the fan through each of the PTC heater assemblies.
