Abstract
An electric heater includes an electric heating coil that extends above the sidewalls of an air flow channel. The coil is formed in sections that extend transversely to the channel and are spaced by the width of a coil section to allow two heaters to be arranged face to face for shipping. This arrangement is very efficient because one of the heaters provides protection to the coil of the other of the heaters to reduce packaging costs.
Claims6
A heater comprising a channel formed by opposed sidewalls and a bottom wall for directing air flow in a first direction and an electric heater element comprising a coil extending across said channel in a second direction transverse to said first direction for heating air flowing in said channel, wherein at least a portion of said electric heater element extends above said sidewalls, a distance that the heater extends above the sidewalls is only sufficient to allow two of said heaters to be packed together in face-to-face relationship with the coils of both heaters nested together.
