Embodiment 1
[0058] Examples of the above-mentioned brazing furnace will be described with reference to the drawings. The brazing furnace 1 of this example is configured to be used for brazing an object to be processed 100 made of an aluminum material. Such as figure 1 As shown, the brazing furnace 1 has: a brazing chamber 2, which is equipped with a heating device 21 for heating the object 100 to the brazing temperature; an inert gas supply device 3, which supplies inert gas to the brazing chamber 2; and a dehumidifier 4. It is interposed between the inert gas supply device 3 and the brazing chamber 2 to dehumidify the inert gas.
[0059] The brazing furnace 1 of this example is configured so that the object 100 to be processed can be placed in or taken out from the furnace through an inlet and outlet provided in the brazing chamber 2 . An openable and closable front door 11 is provided at the entrance and exit of the brazing chamber 2 . The inert gas supply device 3 and the dehumidifi...
Embodiment 2
[0076] This example is an example of a two-chamber type brazing furnace 102 including a brazing chamber 2 and a preheating chamber 5 connected to the brazing chamber 2 . In addition, unless otherwise specified, among the symbols used in the present and subsequent embodiments, the same symbols as those used in the existing embodiments represent the same constituent elements and the like as in the existing embodiments. components, etc.
[0077] Such as figure 2 As shown, the brazing furnace 102 of this example has: a brazing chamber 2; a preheating chamber 5, which is provided with a preheating device 51 for preheating the object 100 to be lower than the brazing temperature, and is connected with the brazing chamber 2 are connected; the pump 52 for preheating, which depressurizes the interior of the preheating chamber 5; .
[0078] The brazing furnace 102 is configured such that the object to be processed 100 can be placed in or taken out from the furnace through an inlet an...
Embodiment 3
[0091] This example is an example of a three-chamber brazing furnace 103 including a preheating chamber 5 , a brazing chamber 2 , and a cooling chamber 6 . Such as image 3 As shown, in the brazing furnace 103 of this example, the preheating chamber 5, the brazing chamber 2 and the cooling chamber 6 are connected in sequence. An inlet for disposing the object 100 to be processed in the furnace is provided in the preheating chamber 5 . A front door 11 is provided at the entrance so as to be openable and closable. Between the preheating chamber 5 and the brazing chamber 2 is provided an openable and closable intermediate door 12 , and between the brazing chamber 2 and the cooling chamber 6 is provided an openable and closable rear door 13 .
[0092] The cooling chamber 6 has an endless belt type conveying device 61 for conveying the processed object 100 . In addition, cooling chamber 6 is provided with an outlet for taking out processed object 100 out of the furnace. An exit...
