Abstract
An airflow deflector including a plurality of spaced apart ribs each extending in a longitudinal direction between a first end and a second end thereof that is generally perpendicular to an airflow stream to be deflected by the airflow deflector such that the plurality of spaced apart ribs induce recirculations of the airflow stream between neighboring ones of the plurality of spaced apart ribs to increase air pressure at an entrance to areas defined between neighboring ribs and restrict the airflow from flowing past the plurality of spaced apart ribs.
Claims16
An airflow deflector comprising:
- a plurality of spaced apart ribs each extending in a longitudinal direction between a first end and a second end thereof that is generally perpendicular to an airflow stream to be deflected by the airflow deflector such that the plurality of spaced apart ribs induce recirculations of the airflow stream between neighboring ones of the plurality of spaced apart ribs to increase air pressure at an entrance to areas defined between neighboring ribs and restrict the airflow from flowing past the plurality of spaced apart ribs;
- wherein a first one of the plurality of spaced apart ribs includes a transverse portion extending transverse to the longitudinal direction;
- and
- wherein the plurality of ribs are included with an HVAC system, the first one of the plurality of ribs is furthest from a base of the HVAC system.
An HVAC system for a motor vehicle comprising:
- an evaporator;
- a heater;
- and
- a plurality of spaced-apart deflector ribs between the evaporator and the heater, the deflector ribs configured to direct airflow away from the heater;
- wherein a first deflector rib of the plurality of deflector ribs includes a first portion and a second portion that is transverse to the first portion;
- wherein the first deflector rib is furthest from a base of the HVAC system;
- and
- wherein the first deflector rib is closest to the heater.
An HVAC system for a motor vehicle comprising:
- an evaporator;
- a heater;
- and
- a plurality of spaced-apart deflector ribs between the evaporator and the heater that extend in a direction generally perpendicular to airflow to be deflected;
- wherein a first one of the deflector ribs includes an elongated portion extending between the heater and the evaporator, and a transverse portion extending perpendicular to the elongated portion, the transverse portion is at an end of the elongated portion proximate to the evaporator;
- wherein the first one of the plurality of ribs is furthest from a base of the HVAC system;
- wherein the first one of the plurality of ribs is closest to the heater;
- and
- wherein the first one of the plurality of ribs is furthest form the evaporator.
