Abstract: An air circulation system configured to mount within a B-pillar, C-pillar, other pillar, or interior trim or cross trims through an air channel of a vehicle. The air circulation system includes a scroll within the pillar, which defines an inlet configured to receive inlet air from a vehicle cabin at the pillar. A fan within the pillar is configured to circulate the inlet air within the scroll. An elongated throat extending from the scroll is configured to receive forced air from the scroll. The throat defines a length and an outlet extending along the length, wherein the outlet delivers the forced air into the vehicle cabin from the pillar in an air stream. The outlet is configured such that the forced air delivered from the outlet creates a Coand? effect that attracts air in the vehicle cabin to move in the direction of the air stream.

Abstract: A heat exchanger includes a core including a plurality of tubes and a plurality of air passages, an air inlet portion in fluid communication with the air passages, and an air outlet portion in fluid communication with the air passages. The tubes and the air passages are alternately arranged to be parallel with each other. The core extends along a core plane defined by the tubes and the air passages. The core is disposed such that the core plane is parallel to a vehicle horizontal plane. Outside air flows through the air passages in a first direction. Thermal medium flows through the tubes in a second direction opposite to the first direction. The air inlet portion is open at a front side of the vehicle or a lateral side of the vehicle. The air outlet portion is open at the front side of the vehicle or the lateral side of the vehicle.
