Abstract: An infrared firing furnace includes a case-integrated cooling system to provide high performance cooling as the first step in the cooling process. The cooling system includes a cooling manifold integrated into, and made from, the same case material as the adjacent firing zone. As the cooling system is made from the same material as the rest of the case, it can handle being exposed to higher temperatures. The cooling system is positioned such that the plane of its outlet is at a specific clearance level relative to the product passing underneath. High pressure cooling jets of air are directed downward toward the products as they pass under the cooling manifold in order to quickly bring the temperature of the products down from the much higher firing temperature, and minimize the dwell time of the product at the higher temperature.

Abstract: Fan includes wires electrically connected to the circuit board outwardly extends from a base toward a housing along a rib connecting the base supporting a motor and the housing. The housing includes a wire-receiving section defined by a through hole extending in the housing, and a slit connecting the through hole and an outside of the housing along a direction in which the through hole extends. The wires are inserted into the wire-receiving section via the slit, and then, led outside of the housing through the wire-receiving section. A wire-holding member is then inserted into the wire-receiving section to close the slit to prevent the wires from coming out of the wire-receiving section and to restrict the movement of the wires.

Abstract: Isolation IR heat lamp module and method of firing multi-zone IR furnaces for solar cell processing comprising lamps disposed in individual parallel channels in a reflector/insulator body to provide a cooling air channel surrounding each tube; the channels are covered with IR-transmissive plate material to isolate each lamp from adjacent lamps and the process zone. Cooling air is exhausted and recycled upstream for energy conservation. Lamp spacing can be varied and power to each lamp individually controlled to provide infinite control of temperature profile in each heating zone. For a spike zone, and in combination with downstream quench control and annealing zones, steep heating and cooling curves with very short dwell (sharp) peak temperature profiles permit faster throughput due to operation of the lampsm at essentially 100% rated capacity, at a 2× or greater heating and throughput rate without compromising lamp life, while producing solar cells with improved output efficiency.
