A modular infrared heating device having an outer casing which encloses a heating chamber wherein one or more infrared lamps are vertically positioned. The heating device also includes an intake channel which communicates with an opening in the outer casing and with the heating chamber. At least one heat exchanging plate is positioned within the heating chamber adjacent to the infrared lamps such that it is capable of being heated thereby and defines an air discharge channel with a wall of the casing and. This plate has a plurality of open-ended tubular conduits mounted onto it. Each of these conduits is constructed to have a hollow inner channel and is mounted onto the heat exchanging plate such that its hollow inner channel is aligned with a corresponding opening in the plate. The conduits extend into the discharge channel transversely of the direction of flow therein and are curved to present end portions extending parallel to the direction of flow in the discharge channel to induce air flow through the conduits. The heating device is also equipped with a fan which facilitates the circulation of air through the heater. Air moving through the heater passes over the infrared lamps, over both sides of the heat exchanging plate, and through and around the tubular conduits such that it is capable of absorbing heat from these components of the device.
