Detailed Description
To further explain the technical means and effects of the present invention adopted to achieve the predetermined object, the following detailed description of the embodiments, structures, features and effects according to the present invention will be made with reference to the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "an embodiment" refers to not necessarily the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
Example 1
As shown in fig. 1 and 2, the present embodiment provides an air duct assembly for use in an air conditioning apparatus, wherein the air duct assembly includes an air duct structure 2, and the air duct structure 2 is used for forming an air duct in the air conditioning apparatus. Wherein the air duct structure 2 comprises a first layer 21 and a second layer 23, which are arranged on top of each other. And, a first hollow cavity 22 for thermal insulation is formed between the first layer 21 and the second layer 23 of the air duct structure 2. Wherein the first layer 21 of the air duct structure 2 serves as an outer wall of the air duct. The second layer 23 of the air duct structure 2 serves as an inner wall of the air duct.
The air duct structure 2 in the embodiment and the following embodiments is mainly used for being installed on an air conditioning device to form an air duct so that cold air cooled by an evaporator passes through the air duct.
The air duct assembly provided by this embodiment is configured as a hollow cavity for thermal insulation between the air duct inner wall and the air duct outer wall of the air duct structural member 2 (because the hollow cavity is air or close to vacuum, the internal airflow thereof hardly flows, and the thermal conductivity coefficient thereof is low, so that it has thermal insulation performance), thereby realizing effective thermal insulation between the air duct inner wall and the air duct outer wall of the air duct structural member 2. In the refrigeration process of the air conditioning equipment, condensation water drops are not easy to form on the outer wall of the air duct (the first layer of the air duct structural member 2), and the condensation problem is effectively solved.

The air duct assembly provided by the embodiment further sets a hollow cavity layer capable of insulating heat and preserving heat between the inner wall and the outer wall of the water pan body 3 in the air duct assembly so as to realize effective heat insulation between the inner wall and the outer wall of the water pan. When air conditioning equipment refrigerates, cold wind and comdenstion water make the temperature of water collector inner wall reduce when the inner wall of water collector body flows through, nevertheless because the thermal-insulated heat retaining effect of second cavity, the water collector outer wall is difficult to form the condensation water droplet, has further effectively solved wind channel subassembly and air conditioning equipment's condensation problem.

Based on the same temperature condition, the air in the hollow part has a heat conductivity coefficient close to that of the heat insulation foam, and has a similar heat insulation effect. Different thicknesses are set according to the temperature difference between the air outlet temperature of the air duct and the dew point temperature of condensation. In this embodiment, the thicknesses of the first layer, the second layer and the first hollow cavity of the air duct structural member are designed as follows: the thickness of the first layer of the air duct structural member is 1; the thickness of the second layer of the air duct structural member is 3; the thickness of the first hollow cavity is 2; wherein, 1mm is less than or equal to 1mm and less than or equal to 6 mm; 1 is not less than 2 and not more than 151; 0.51 is less than or equal to 3 is less than or equal to 1.21.
