Abstract
An apparatus for a heating, ventilating and air conditioning system may include an outer shell and a honeycomb structure. The outer shell may define an interior volume having an inlet and an outlet providing an airflow path therethrough. The honeycomb structure may be attached to the outer shell and disposed in the airflow path. The honeycomb structure may include a plurality of polygonal apertures extending substantially in a direction of the airflow. The honeycomb structure may deflect sound waves away from a predetermined area.
Claims19
An apparatus for a heating, ventilating and air conditioning system comprising:
- an outer shell defining an interior volume having an inlet and an outlet providing an airflow path therethrough;
- and
- a honeycomb structure attached to the outer shell and disposed in the airflow path, the honeycomb structure including a plurality of polygonal apertures extending substantially in a direction of the airflow,
- wherein the honeycomb structure deflects sound waves away from a predetermined area.
A heating, cooling and ventilation system comprising:
- a fan in fluid communication with at least one of one of a first air inlet and a second air inlet;
- a shell at least partially defining an airflow path between the fan and the at least one of the first air inlet and the second air inlet;
- and
- a honeycomb structure disposed on the shell, the honeycomb structure including a plurality of polygonal apertures allowing air to flow therethrough and direct sound waves away from a predetermined area.
A vehicle heating, cooling and ventilation system comprising:
- a fan in fluid communication with a first air inlet and a second air inlet;
- a motor that drives the fan;
- and
- a case at least partially defining an airflow path between the fan and the first and second air inlets, the case including a door and a honeycomb structure, the door being selectively movable to allow and prevent fluid communication between the fan and the first air inlet and between the fan and the second air inlet,
- wherein the honeycomb structure includes a plurality of hexagonal apertures adapted to direct sound waves away from a predetermined area.
The vehicle heating cooling and ventilation system of claim 18, wherein each of the plurality of hexagonal apertures has a width between hexagonal faces of between 7 millimeters to 10 millimeters and a depth of about 12 mm.
