Abstract

A heater assembly includes a housing which both channels air flowing around a heating element and provides support structure for the elements holding the heating element. In one embodiment, a lower U-shaped channel has recesses in opposed sidewalls to engage down-turned ends of holding elements. A second U-shaped channel is attached to form a hollow duct open at opposite ends. In a second embodiment, a U-shaped channel is made of flexible material so that the spacing between opposed sidewalls may be varied. A holding element is secured between the sidewalls by separating the sidewalls to allow insertion of the holding means.
