ABSTRACT:
Air temperature regulating apparatus for a vehicle including a unit case having an air-intake chamber, an air-intake window, a mixing chamber, and a heat exchanger mounted between the air-intake chamber and the mixing chamber. A side air exit, and a bottom air exit are provided in the mixing chamber. The heat exchanger includes plural air-heating passages with plural heat-radiating fins mounted in alternating ones of the passages and a damper slideably mounted in front of the exchanger variably adjustable to change an opening area of the passages. The exchanger can be formed of a flattened empty pipe having both ends remaining round with the pipe being bent in a zig-zag shape with the flattened portions extending horizontally. The heat-radiating fins in one portion of the exchanger can have a larger surface area than those mounted in an opposite portion. In the alternative, the relative heights of the air-heating passages can be changed from one end portion of the exchanger to another end portion of the exchanger.
