Abstract
An airflow baffle for controlling airflow through a heating, ventilation, and air conditioning (HVAC) system. The airflow baffle includes a main body, an upstream side of the main body, and a downstream side of the main body. A plurality of holes are defined by the main body, and extend through the main body between the upstream side and the downstream side. The plurality of holes include holes of various different diameters spaced apart at various different intervals to provide uniform airflow through the baffle.
Claims19
An airflow baffle for controlling airflow through a heating, ventilation, and air conditioning (HVAC) system, the airflow baffle comprising:
- a main body;
- an upstream side of the main body;
- a downstream side of the main body;
- and
- a plurality of holes defined by the main body and extending through the main body between the upstream side and the downstream side, the plurality of holes including holes of various different diameters spaced apart at various different intervals to provide uniform airflow through the baffle;
- wherein the baffle is arranged in the HVAC system downstream of a blower of the HVAC system.
An airflow baffle for controlling airflow through a heating, ventilation, and air conditioning (HVAC) system, the airflow baffle comprising:
- a main body;
- an upstream side of the main body;
- a downstream side of the main body;
- a plurality of holes defined by the main body and extending through the main body between the upstream side and the downstream side;
- and
- a plurality of guide vanes extending from the main body to divide the plurality of holes into different groups, guide airflow through the plurality of holes, and break down incoming air vortexes;
- wherein the baffle is arranged in the HVAC system downstream of a blower of the HVAC system.
A heating, ventilation, and air conditioning (HVAC) system comprising:
- an airflow blower;
- an HVAC case including a heater core;
- and
- an airflow baffle in an airflow path through the HVAC system, the airflow baffle including:
- a main body;
- an upstream side of the main body;
- a downstream side of the main body;
- and
- a plurality of holes defined by the main body and extending through the main body between the upstream side and the downstream side;
- and
- a plurality of guide vanes extending from the upstream side of the main body to divide the plurality of holes into different groups, guide airflow through the plurality of holes, and break down incoming air vortexes;
- wherein:
- amongst the different groups the plurality of holes have different diameters to provide uniform airflow through the baffle;
- amongst the different groups the plurality of holes are spaced apart differently to provide uniform airflow through the baffle;
- and
- within each group the plurality of holes have a common diameter and are evenly spaced apart.
