摘要： In a manufacturing method of a heat exchanger including a core portion (11) having a plurality of tubes (13) and a plurality of radiation fins (14) connected to surfaces of the tubes, and a tank portion (12) communicating with the tubes, a preheating step, a brazing step, a gradual cooling step and a cooling step are performed in this order. In the preheating step, temperature of the tank portion having a large heat capacity is increased earlier than that of the core portion having a small heat capacity. Therefore, the temperature of the tank portion is rapidly increased, and the temperature of the core portion is obediently increased in accordance with the temperature increase of the tank portion.

摘要： PROBLEM TO BE SOLVED: To provide a direct fire gas burner furnace capable of maintaining a furnace interior at a set temperature while reducing exhaust heat loss, saving energy, and reducing a CO
2 exhaust amount.
SOLUTION: In the direct fire gas burner furnace, an object 13 to be heated is directly heated by combustion gas, and the combustion gas is exhausted out of the furnace. An exhaust amount of the combustion gas in the furnace is controlled by controlling a burning capacity of a gas burner 2 on the basis of an in-furnace temperature detected by a temperature sensor 3 in the furnace, and controlling a rotational frequency of an exhaust fan 8 on the basis of the burning capacity. Consequently, combustion gas of an amount appropriating an amount of the combustion gas introduced into the furnace can be exhausted out of the furnace, and suction of outside air of an ordinary temperature into the furnace can be prevented.
