[0002] At present, for the air duct structure with replaceable air outlet, since the volute tongue is rotatably arranged in the volute, there is a gap between the outer surface of the volute tongue and the inner surface of the volute case. When the volute tongue blocks an air outlet, The gas will flow out from another air outlet through the gap between the volute tongue and the volute. The above structure destroys the integrity of the air duct, air leakage and condensation, and affects heat transfer.
In addition, because the volute needs to rotate, when the volute tongue blocks any air outlet, the inner surface of the volute tongue and the inner surface of the volute are not a smooth transition, which will inevitably destroy the integrity of the air duct and also affect heat transfer

Embodiment Construction
[0022] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0023] see figure 1 and figure 2 , the air duct structure of this embodiment includes a volute 10 , a volute tongue 20 , a first sealing device 30 and a second sealing device 40 . The volute 10 has a first air outlet 11 and a second air outlet 12 . The volute tongue 20 is located inside the volute 10 , and the volute tongue 20 has a first shielding state for shielding the first air outlet 11 and a second shielding state for shielding the second air outlet 12 . The first sealing device 30 includes a first sealing member 31 and a first driving member 32 that drives the first sealing member 31 to move, and the first sealing member 31 has a first sealing state that blocks the gap between the vo...

The invention provides an air duct structure and a heat exchanger with the same. The air duct structure comprises a volute, a volute tongue, a first sealing device and a second sealing device, wherein the volute is provided with a first air outlet and a second air outlet; the volute tongue is positioned in the volute and has a first shielding state and a second shielding state; the first sealing device comprises a first sealing element, and the first sealing element has a first plugging state capable of shielding a clearance between the volute tongue and the volute and a first avoiding state capable of avoiding the volute tongue; when the volute tongue is in the first shielding state, the first sealing element is in the first plugging state; the second sealing device comprises a second sealing element, and the second sealing element has a second plugging state and a second avoiding state; when the volute tongue is in the second shielding state, the second sealing element is in the second plugging state. By virtue of the technical scheme, air leakage can be avoided.
Description
technical field [0001] The invention relates to the technical field of air outlet devices, in particular to an air duct structure and a heat exchanger having the same. Background technique [0002] At present, for the air duct structure with replaceable air outlet, since the volute tongue is rotatably arranged in the volute, there is a gap between the outer surface of the volute tongue and the inner surface of the volute case. When the volute tongue blocks an air outlet, The gas will flow out from another air outlet through the gap between the volute tongue and the volute. The above-mentioned structure destroys the integrity of the air duct, causes air leakage and condensation, and affects heat exchange. In addition, because the volute needs to rotate, when the volute tongue blocks any air outlet, the inner surface of the volute tongue and the inner surface of the volute are not a smooth transition, which will inevitably destroy the integrity of the air duct and also affect ...
