Compared with the prior art, the two sides and the bottom of each external furnace in the hydrogen tunnel furnace are connected with the air supply device through the pipelines, and the hydrogen can be distributed in the external furnace more fully due to the small density of the hydrogen, so that a fire curtain can be formed at the mouth of the external furnace fully, external air is effectively isolated from entering the furnace, no fire curtain with flame at the bottom of the external furnace can be generated, the influence on the atmosphere in the furnace due to the air entering the furnace is avoided, and the sintering quality of ceramic circuit elements is reduced. Meanwhile, the gate is connected with the external furnace through the connecting component, compared with the traditional direct welding, the deformation of the joint of the gate and the external furnace is smaller, the flatness of the gate is effectively guaranteed, the gate has better sealing performance when being closed, the situation that the hydrogen in the external furnace leaks from the periphery to form a flame is avoided, and the hydrogen tunnel furnace has better atmosphere.
