Rolling door guide area heating method and system

A method for heating a door guide area comprising:

• channeling heated air in a first direction in a first conduit;
• channeling the heated air in a second direction different than the first direction in a second conduit;
• providing the heated air to the first and second conduits from a heater fluidly connected to the first conduit;
• providing fluid communication between the first and second conduits through a first opening;
• providing fluid communication between the first and second conduits through a second opening, wherein the first and second openings are formed in a wall separating the first conduit from the second conduit and the first and second openings allow the heated air provided by the heater to circulate through the first and second conduits;
• channeling the heated air from the first conduit back to the heater after the heated air has moved through the first and second conduits;
• drawing the heated air into the heater from the first conduit;
• and
• transferring heat with a heat transfer wall defining part of the second conduit from the heated air in the second conduit to a chamber outside of the second conduit;
• wherein two side supports are connected to the heat transfer wall, the side supports opposing each other to form, with the heat transfer wall, three sides of the chamber.

A system for heating a door guide area comprising:

• a first conduit for channeling heated air in a first direction;
• a second conduit for channeling the heated air in a second direction opposite the first direction;
• a heater fluidly connected to the first conduit and configured to provide the heated air to the first and second conduits;
• a first opening providing fluid communication between the first and second conduits;
• a second opening providing fluid communication between the first and second conduits, wherein the first and second openings allow the heated air provided by the heater to circulate through the first and second conduits;
• a heat transfer wall defining part of the second conduit, the heat transfer wall configured to transfer heat from the heated air in the second conduit to a chamber outside of the second conduit that is defined, in part, by the heat transfer wall;
• heat transfer fins for collecting heat from the heated air in the second conduit, the heat transfer fins being attached to the heat transfer wall and extending into the second conduit;
• and
• two side supports connected to the heat transfer wall, the side supports opposing each other to form, with the heat transfer wall, three sides of the chamber for guiding and encompassing an edge of a side portion of a roll-up door when the roll-up door is closing and when the roll-up door is in a closed position, wherein the two side supports are constructed from a thermally insulating material;
• wherein there are no heat transfer fins present in the chamber outside of the second conduit that is defined in part by the heat transfer wall.
