Patent ID: 8397795

Claim:
A heat exchanger for use in a vehicular air conditioning apparatus having a casing including first and second passages through which air flows, and a damper mechanism for switching a flow state of the air in the passages, and first and second blowers for supplying air respectively to the interior of the casing, wherein the heat exchanger is disposed in the interior of the casing so as to straddle between the first passage and the second passage, for thereby cooling and heating the air and supplying the air, the heat exchanger comprising: a plurality of tubes through which a medium flows in the interior thereof; a first fin disposed on a first heat exchanger section, the first fin being bent in a wavy shape and having an air hole therein through which the air flows, for carrying out heat exchange on the air that flows through the first passage inside the casing; a second fin disposed on a second heat exchanger section, the second fin being bent in a wavy shape and having an air hole therein through which the air flows, for carrying out heat exchange on the air that flows through the second passage; and a partitioning member provided separately from the first and second fins and disposed between the first heat exchanger section and the second heat exchanger section, wherein the first fin and the second fin are separate and distinct from each other, wherein the partitioning member is disposed between each of the plurality of tubes and affixed to the tubes adjacent thereto so as to block the air from flowing between the first heat exchanger section and the second heat exchanger section.
