Patent ID: 8720529

Claim:
A heat exchanger for use in a vehicular air conditioning apparatus, the heat exchanger comprising: a first surface and a second surface disposed in parallel to each other, the heat exchanger heating or cooling air by passing air through the first surface and then the second surface or vise versa; a plurality of first and second tubes through which a medium flows in the interior of the plurality of the first and second tubes, the plurality of first tubes forming the first surface, and the plurality of second tubes forming the second surface, wherein the heat exchanger comprises a plurality of gaps between the plurality of first tubes and the plurality of second tubes; a first heat exchanger section, a boundary portion, and a second heat exchanger section arranged in this order in a direction parallel to directions of the plurality of the first and second tubes, the boundary portion extending in a direction perpendicular to a direction in which the plurality of first and second tubes extend; a plurality of first fins disposed on the first heat exchanger section and a plurality of second fins disposed on the second heat exchanger section, the plurality of the first and second fins being bent in a wavy shape between the plurality of the first and second tubes and having air holes in the plurality of the first and second fins through which the air flows, wherein no fins are disposed in the boundary portion; and a partition member, which is formed in the boundary portion between the plurality of the first and second tubes and at the plurality of the gaps between the plurality of the first tubes and the plurality of the second tubes, wherein the partition member is made of a liquid deposited synthetic resin or rubber that hardens into the partition member and in contact with the plurality of the first and second tubes, end surfaces of the plurality of the first fins at the boundary portion, and end surfaces of the plurality of the second fins at the boundary portion, the end surfaces of the plurality of the first and second fins being perpendicular to a direction in which the plurality of the first and second tubes extend, such that the partition member blocks the air from flowing between the first heat exchanger section and the second heat exchanger section.
